I am trying to send a string to the EventHub and I have written this code:
private static void sendPOST(ValueChangeMessage valueChangeMessage) throws IOException {
try {
// final String namespaceName = ""; //sericebusnamespacename
// final String eventHubName = "";
// final String sasKeyName = "";
// final String sasKey = "";
// ConnectionStringBuilder connStr = new ConnectionStringBuilder(namespaceName, eventHubName, sasKeyName, sasKey);
byte[] payloadBytes = valueChangeMessage.data.get().toString().getBytes(StandardCharsets.UTF_8);
EventData sendEvent = new EventData(payloadBytes);
EventHubClient ehClient = EventHubClient.createFromConnectionStringSync(connStr.toString());
ehClient.sendSync(sendEvent);
}
catch (ServiceBusException ex) {
Logger.getLogger(CatChannel.class.getName()).log(Level.SEVERE, null, ex);
}
}
But whenever I try to run the project from netbeans , it
gives the error below:
error: cannot access Message
sendEvent = new EventData(payloadBytes);
class file for org.apache.qpid.proton.message.Message not found
Can anyone tell me what can be the possible issue??
I got the fix for this..........actually the issue was with the proxies of the system.....it wasnt able to download the jars from maven.....So i manually included the dependencies in my project

Firstly I had a problem with the antiJARLocking attribute that was showing an error in the console:
WARNING [http-nio-8084-exec-69] org.apache.catalina.startup.SetContextPropertiesRule.begin [SetContextPropertiesRule] {Context} Setting property 'antiJARLocking' to 'true' did not find a matching property.
But I commented this part and it does not appear anymore.
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/DivulgueAqui"/>
<!-- antiJARLocking="true" -->
Then got a bug with the netbeans monitor
Showing this error:
The request can not be recorded most likely because the NetBeans HTTP Monitor module is disabled.
But in my last tests to get this error and put here for you this did not happen!
When I'm trying to run the web service it returns me code 500.
The information is arriving in the method and insert but when it arrives in the dao.insert (u);
The service stops working
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Path("usuario/inserir")
public String insertUsuario(String json){
UsuarioDao dao = new UsuarioDao();
Usuario u = new Usuario();
JSONObject jsonObject = null;
JSONParser parser = new JSONParser();
String nome;
String email;
String senha;
try {
jsonObject = (JSONObject) parser.parse(json);
nome = (String) jsonObject.get("nome");
email = (String)jsonObject.get("email");
senha = (String) jsonObject.get("senha");
u.setNome(nome);
u.setEmail(email);
u.setSenha(senha);
dao.inserir(u);
} catch (ParseException ex) {
System.out.println("WS.webService.insertUsuario()" + ex);
Logger.getLogger(webService.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
My question is. How do I solve this problem?
We have some code that downloads a bunch of S3 files to a local directory. The list of files to retrieve is from a query we run. It only lists files that actually exist in our S3 bucket.
As we loop to retrieve these files, about 10% of them return a 404 error as if the file doesn't exist. I log out the name/location of that file, so I can go to S3 and check, and sure enough every single one of the IS ON S3 in the location we went looking for it.
Why does S3 throw a 404 when the file exists?
Here is the Groovy code of the script.
class RetrieveS3FilesFromCSVLoader implements Loader {
private static String missingFilesFile = "00-MISSED_FILES.csv"
private static String csvFileName = "/csv/s3file2.csv"
private static String saveFilesToLocation = "/tmp/retrieve/"
public static final char SEPARATOR = ','
#Autowired
DocumentFileService documentFileService
private void readWithCommaSeparatorSQL() {
int counter = 0
String fileName
String fileLocation
File missedFiles = new File(saveFilesToLocation + missingFilesFile)
PrintWriter writer = new PrintWriter(missedFiles)
File fileCSV = new File(getClass().getResource(csvFileName).toURI())
fileCSV.splitEachLine(SEPARATOR as String) { nextLine ->
//if (counter < 15) {
if (nextLine != null && (nextLine[0] != 'FileLocation')) {
counter++
try {
//Remove 0, only if client number start with "0".
fileLocation = nextLine[0].trim()
byte[] fileBytes = documentFileService.getFile(fileLocation)
if (fileBytes != null) {
fileName = fileLocation.substring(fileLocation.indexOf("/") + 1, fileLocation.length())
File file = new File(saveFilesToLocation + fileName)
file.withOutputStream {
it.write fileBytes
}
println "$counter) Wrote file ${fileLocation} to ${saveFilesToLocation + fileLocation}"
} else {
println "$counter) UNABLE TO RETRIEVE FILE ELSE: $fileLocation"
writer.println(fileLocation)
}
} catch (Exception e) {
println "$counter) UNABLE TO RETRIEVE FILE: $fileLocation"
println(e.getMessage())
writer.println(fileLocation)
}
} else {
counter++;
}
//}
}
writer.close()
}
Here is the code for getFile(fileLocation) and client creation.
public byte[] getFile(String filename) throws IOException {
AmazonS3Client s3Client = connectToAmazonS3Service();
S3Object object = s3Client.getObject(S3_BUCKET_NAME, filename);
if(object == null) {
return null;
}
byte[] fileAsArray = IOUtils.toByteArray(object.getObjectContent());
object.close();
return fileAsArray;
}
/**
* Connects to Amazon S3
*
* #return instance of AmazonS3Client
*/
private AmazonS3Client connectToAmazonS3Service() {
AWSCredentials credentials;
try {
credentials = new BasicAWSCredentials(S3_ACCESS_KEY_ID, S3_SECRET_ACCESS_KEY);
} catch (Exception e) {
throw new AmazonClientException(
"Cannot load the credentials from the credential profiles file. " +
"Please make sure that your credentials file is at the correct " +
"location (~/.aws/credentials), and is in valid format.",
e);
}
AmazonS3Client s3 = new AmazonS3Client(credentials);
Region usWest2 = Region.getRegion(Regions.US_EAST_1);
s3.setRegion(usWest2);
return s3;
}
The code above works for 90% of the files in the list passed to the script, but we know with fact that all 100% of the files exist in S3 and with the location String we are passing.
I am just an idiot. Thought it had the production AWS credentials in the properties file. Instead it was development credentials. So I had the wrong credentials.
I'm trying to create Internal Accounts programmaticaly by using proc metadata.
The code section below creates person with External Login.
put"<Person Name=%str(%')&&PersonName&i.%str(%')>";
put"<Logins>";
put"<Login Name=%str(%')Login.&&PersonName&i.%str(%') Password=%str(%')&&word&i.%str(%')/>";
put"</Logins>";
put"</Person>";
To create ExternalLogin we can set attribute Password, and in SAS Metadata it will be encrypted automaticaly.
But to create InternalLogin type of object it is necessary to make the hash value of the password and the salt. I know that the standard sas002 encryption method, but in the case of using proc pwencode how to obtain the value of salt?
Is it possible create InternalLogin by using SAS Base?
Thanx.
So on. I found an article that can tell us how to create Stored Process for this problem. My answer is addition to the article.
The approach is base on execute java methods from sas programm.
1. Prerare setPasswd.java class
I've modified class from article. Separate code to connect to metadata server and create InternalLogin
import java.rmi.RemoteException;
import com.sas.metadata.remote.AssociationList;
import com.sas.metadata.remote.CMetadata;
import com.sas.metadata.remote.Person;
import com.sas.metadata.remote.MdException;
import com.sas.metadata.remote.MdFactory;
import com.sas.metadata.remote.MdFactoryImpl;
import com.sas.metadata.remote.MdOMIUtil;
import com.sas.metadata.remote.MdOMRConnection;
import com.sas.metadata.remote.MdObjectStore;
import com.sas.metadata.remote.MetadataObjects;
import com.sas.metadata.remote.PrimaryType;
import com.sas.metadata.remote.Tree;
import com.sas.meta.SASOMI.ISecurity_1_1;
import com.sas.iom.SASIOMDefs.VariableArray2dOfStringHolder;
public class setPasswd {
String serverName = null;
String serverPort = null;
String serverUser = null;
String serverPass = null;
MdOMRConnection connection = null;
MdFactoryImpl _factory = null;
ISecurity_1_1 iSecurity = null;
MdObjectStore objectStore = null;
Person person = null;
public int connectToMetadata(String name, String port, String user, String pass){
try {
serverName = name;
serverPort = port;
serverUser = user;
serverPass = pass;
_factory = new MdFactoryImpl(false);
connection = _factory.getConnection();
connection.makeOMRConnection(serverName, serverPort, serverUser, serverPass);
iSecurity = connection.MakeISecurityConnection();
return 0;
}catch(Exception e){
return 1;
}
}
public setPasswd(){};
public int changePasswd(String IdentityName, String IdentityPassword) {
try
{
//
// This block obtains the person metadata ID that is needed to change the password
//
// Defines the GetIdentityInfo 'ReturnUnrestrictedSource' option.
final String[][] options ={{"ReturnUnrestrictedSource",""}};
// Defines a stringholder for the info output parameter.
VariableArray2dOfStringHolder info = new VariableArray2dOfStringHolder();
// Issues the GetInfo method for the provided iSecurity connection user.
iSecurity.GetInfo("GetIdentityInfo","Person:"+IdentityName, options, info);
String[][] returnArray = info.value;
String personMetaID = new String();
for (int i=0; i< returnArray.length; i++ )
{
System.out.println(returnArray[i][0] + "=" + returnArray[i][1]);
if (returnArray[i][0].compareTo("IdentityObjectID") == 0) {
personMetaID = returnArray[i][1];
}
}
objectStore = _factory.createObjectStore();
person = (Person) _factory.createComplexMetadataObject(objectStore, IdentityName, MetadataObjects.PERSON, personMetaID);
iSecurity.SetInternalPassword(IdentityName, IdentityPassword);
person.updateMetadataAll();
System.out.println("Password has been changed.");
return 0; // success
}
catch (MdException e)
{
Throwable t = e.getCause();
if (t != null)
{
String ErrorType = e.getSASMessageSeverity();
String ErrorMsg = e.getSASMessage();
if (ErrorType == null)
{
// If there is no SAS server message, write a Java/CORBA message.
}
else
{
// If there is a message from the server:
System.out.println(ErrorType + ": " + ErrorMsg);
}
if (t instanceof org.omg.CORBA.COMM_FAILURE)
{
// If there is an invalid port number or host name:
System.out.println(e.getLocalizedMessage());
}
else if (t instanceof org.omg.CORBA.NO_PERMISSION)
{
// If there is an invalid user ID or password:
System.out.println(e.getLocalizedMessage());
}
}
else
{
// If we cannot find a nested exception, get message and print.
System.out.println(e.getLocalizedMessage());
}
// If there is an error, print the entire stack trace.
e.printStackTrace();
}
catch (RemoteException e)
{
// Unknown exception.
e.printStackTrace();
}
catch (Exception e)
{
// Unknown exception.
e.printStackTrace();
}
System.out.println("Failure: Password has NOT been changed.");
return 1; // failure
}
}
2. Resolve depends
Pay attention to imports in class. To enable execute the code below necessary set CLASSPATH enironment variable.
On linux you can add the next command in %SASConfig%/Lev1/level_env_usermods.sh:
export CLASSPATH=$CLASSPATH:%pathToJar%
On Windows you can add/change environment variable by Advanced system settings
So where should you search jar files? They are in folder:
%SASHome%/SASVersionedJarRepository/eclipse/plugins/
Which files i should include in path?
I've include all that used in OMI(Open Metadata Interface).Also I've added log4j.jar (not working without this jar. Your promts will be helpful):
sas.oma.joma.jar
sas.oma.joma.rmt.jar
sas.oma.omi.jar
sas.svc.connection.jar
sas.core.jar
sas.entities.jar
sas.security.sspi.jar
log4j.jar
setPasswd.jar (YOUR JAR FROM THE NEXT STEP!)
Choose files from nearest release. Example:
Here I'm set file from v940m3f (fix release).
Other ways is here.
3. Compile setPasswd.jar
I'm tried use internal javac.exe into SAS, but it's not worked properly. So ou need to download JDK to compile jars. I've create Bat-file:
"C:\Program Files\Java\jdk1.8.0_121\bin\javac.exe" -source 1.7 -target 1.7 setPasswd.java
"C:\Program Files\Java\jdk1.8.0_121\bin\jar" -cf setPasswd.jar setPasswd.class
Paramethers -source and -target will helpful if your version of JDK is upper, that usses in SAS. Version of "sas"-java you can see by:
PROC javainfo all;
run;
Search the next string in log:
java.vm.specification.version = 1.7
4. Finally. SAS Base call
Now we can call Java code by this method (All methods available here):
data test;
dcl javaobj j ("setPasswd");
j.callIntMethod("connectToMetadata", "%SERVER%", "%PORT%", "%ADMIN%", "%{SAS002}HASHPASSORPASS%", rc1);
j.callIntMethod("changePasswd", "testPassLogin", "pass1", rc2);
j.delete();
run;
In log:
UserClass=Normal
AuthenticatedUserid=Unknown
IdentityName=testPass
IdentityType=Person
IdentityObjectID=A56RQPC2.AP00000I
Password has been changed.
Now time to test. Create new user with no passwords.
Execute code:
data test;
dcl javaobj j ("setPasswd");
j.callIntMethod("connectToMetadata", "&server.", "&port.", "&adm", "&pass", rc1);
j.callIntMethod("changePasswd", "TestUserForStack", "Overflow", rc2);
j.delete();
run;
Now our user has InternalLogin object.
Thanx.
Searched quite a bit. The problem with these errors is that while the text might appear the same, the problem is always different.
My service takes ONE string value and returns a string response. Here is my code:
private class UploadStats extends AsyncTask<String, Void, String>
{
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://192.168.1.101/rss/RSS_Service.asmx?WSDL";
private static final String INSERTURLACTION = "http://192.168.1.101/rss/RSS_Service.asmx/InsertURL";
private static final String INSERTURLMETHOD = "InsertURL";
#Override
protected String doInBackground(String... url)
{
String status = "";
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
INSERTURLMETHOD);
request.addProperty("url", "www.yahoo.com");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
try
{
httpTransport.call(INSERTURLACTION, envelope);
SoapObject response = (SoapObject) envelope.bodyIn;
status = response.getProperty(0).toString();
}
catch (Exception exception)
{
Log.d("Error", exception.toString());
}
if(status.equals("1"))
{
Log.d("InsertURL", "New URL Inserterd");
}
else if(status.equals("0"))
{
Log.d("InsertURL", "URL Exists. Count incremented");
}
else
{
Log.d("InsertURL", "Err... No");
}
return status;
}
}
I get the error:
java.lang.classcastexception org.ksoap2.SoapFault
What am I doing wrong? If any more details are needed, I can add them.
The error was related to the webservice.
An incorrect namespace on the service side can cause this error (as can a lot of other problems).
Best way to check is to run the webservice on the local machine (where the service is hosted).
We've created a custom webservice in Umbraco to add (async) files and upload them. After upload the service is called with node and file-information to add a new node to the content tree.
At first our main problem was that the service was running outside of the Umbraco context, giving strange errors with get_currentuser.
Now, we inherit the umbraco BaseWebService from the umbraco.webservices dll and we've set all acces information in the settings file; we authenticatie before doing anything else using (correct and ugly-hardcoded) administrator.
When we now execute the webservice (from the browser or anything else) we get:
at umbraco.DataLayer.SqlHelper`1.ExecuteReader(String commandText, IParameter[] parameters)
at umbraco.cms.businesslogic.CMSNode.setupNode()
at umbraco.cms.businesslogic.web.Document.setupNode()
at umbraco.cms.businesslogic.CMSNode..ctor(Int32 Id)
at umbraco.cms.businesslogic.Content..ctor(Int32 id)
at umbraco.cms.businesslogic.web.Document..ctor(Int32 id)
at FileUpload.AddDocument(String ProjectID, String NodeID, String FileName)*
Where AddDocument is our method. The node (filename w/o extension) does not exist in the tree (not anywhere, it's a new filename/node). We've cleared the recycle bin, so it's not in there either.
Are we missing something vital, does anyone has a solution?

We've rewritten the whole procedure (dumped all code and restart) and we've got it working now.
I think we've been messing around with the old code so much in trying to get it to work we were missing some key issues, because it functions.
Thanks for thinking along anyway!
