how to run cloudTask in localhost java11 standard gcp - google-cloud-platform

I have google app engine project taht i finish upgrade from java 8 to java 11.
I also upgraded TaskQueque to cloudTask and every working but how i can run cloudTask on localHost?
this is my old code
Queue queue = QueueFactory.getDefaultQueue();
TaskOptions taskOptions = TaskOptions.Builder.withUrl("/" + backgroundTaskParams.getUrl());
taskOptions.retryOptions(RetryOptions.Builder.withTaskRetryLimit(backgroundTaskParams.getRetryLimit()));
taskOptions.countdownMillis(backgroundTaskParams.getStartDelay());
Map<String, String> params = backgroundTaskParams.getParams();
if(params != null){
for (String key : params.keySet()) {
taskOptions.param(key, params.get(key));
}
}
TaskHandle taskHandle = queue.add(taskOptions);
is not working on java 11 standard gcp
so I upgrade to this code
try (CloudTasksClient client = CloudTasksClient.create()) {
RetryConfig retyConfig = RetryConfig.builder()
.setMaxRetries(backgroundTaskParams.getRetryLimit())
.build();
String queueName = QueueName.of(EMF.getProjectId(), "us-central1", "default").toString();
String payload = Utilities.buildUrlParams(backgroundTaskParams.getParams());
long startTime = (ApplicationServicesManager.getInstance().getTimeManager().getCurrentTime() + backgroundTaskParams.getStartDelay()) / 1000;
Task.Builder taskBuilder = Task.newBuilder();
taskBuilder.setAppEngineHttpRequest(
AppEngineHttpRequest.newBuilder()
.setRelativeUri("/" + backgroundTaskParams.getUrl())
.setHttpMethod(HttpMethod.POST)
.setBody(ByteString.copyFrom(payload, Charset.defaultCharset()))
.build());
taskBuilder.setScheduleTime(
Timestamp.newBuilder()
.setSeconds(startTime));
taskBuilder.setDispatchCount(1);
Task task = taskBuilder.build();
Task taskResponse = client.createTask(queueName, task);
}
//
catch (Exception e) {
NotificationsManager.sendLogException(e);
}
the new code working fine in production server but when I run in localhost
the code create task in production server so i cannot debugging and is not good :)
so how I can to start task in localHost
thank you

Google Application Credentials set and not found

I have an Amazon EC2 with Linux Instance set up and running for my Java Web Application to consume REST requests. The problem is that I am trying to use Google Cloud Vision in this application to recognize violence/nudity in users pictures.
Accessing the EC2 in my Terminal, I set the GOOGLE_APPLICATION_CREDENTIALS by the following command, which I found in the documentation:
export GOOGLE_APPLICATION_CREDENTIALS=<my_json_path.json>
Here comes my first problem: When I restart my server, and ran 'echo $GOOGLE_APPLICATION_CREDENTIALS' the variable is gone. Ok, I set it to the bash_profile and bashrc and now it is ok.
But, when I ran my application, consuming the above code, to get the adult and violence status of my picture, I got the following error:
java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.
My code is the following:
Controller:
if(SafeSearchDetection.isSafe(user.getId())) {
if(UserDB.updateUserProfile(user)==false){
throw new SQLException("Failed to Update");
}
} else {
throw new IOException("Explicit Content");
}
SafeSearchDetection.isSafe(int idUser):
String path = IMAGES_PATH + idUser + ".jpg";
try {
mAdultMedicalViolence = detectSafeSearch(path);
if(mAdultMedicalViolence.get(0) > 3)
return false;
else if(mAdultMedicalViolence.get(1) > 3)
return false;
else if(mAdultMedicalViolence.get(2) > 3)
return false;
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return true;
detectSafeSearch(String path):
List<AnnotateImageRequest> requests = new ArrayList<AnnotateImageRequest>();
ArrayList<Integer> adultMedicalViolence = new ArrayList<Integer>();
ByteString imgBytes = ByteString.readFrom(new FileInputStream(path));
Image img = Image.newBuilder().setContent(imgBytes).build();
Feature feat = Feature.newBuilder().setType(Type.SAFE_SEARCH_DETECTION).build();
AnnotateImageRequest request = AnnotateImageRequest.newBuilder().addFeatures(feat).setImage(img).build();
requests.add(request);
ImageAnnotatorClient client = ImageAnnotatorClient.create();
BatchAnnotateImagesResponse response = client.batchAnnotateImages(requests);
List<AnnotateImageResponse> responses = response.getResponsesList();
for (AnnotateImageResponse res : responses) {
if (res.hasError()) {
System.out.println("Error: "+res.getError().getMessage()+"\n");
return null;
}
SafeSearchAnnotation annotation = res.getSafeSearchAnnotation();
adultMedicalViolence.add(annotation.getAdultValue());
adultMedicalViolence.add(annotation.getMedicalValue());
adultMedicalViolence.add(annotation.getViolenceValue());
}
for(int content : adultMedicalViolence)
System.out.println(content + "\n");
return adultMedicalViolence;
My REST application was built above a Tomcat8. After no success running the command:
System.getenv("GOOGLE_APPLICATION_CREDENTIALS")
I realize that my problem was in the Environment Variables to Tomcat installation. To correct this, I just created a new file setenv.sh in my /bin with the content:
GOOGLE_APPLICATION_CREDENTIALS=<my_json_path.json>
And it worked!

Call a python code from WCF

I need to make a python code available as WCF for another application to access it. The python code was build by the data science team and have no ability to change it. I tried running the program as a process shell but it gives 'System.InvalidOperationException' exception.
I created the same program as C# console application and it works fine. The question is
a. Is this the right way to go about making python code available to another application (REST API is not an option).
b. What is the issue with my code.
public string ClassifyText(string value)
{
string textoutput = "";
string exeFileName = HttpContext.Current.Server.MapPath("~/python.exe");
string argName = HttpContext.Current.Server.MapPath("~/predictionscript.py");
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = exeFileName;
start.Arguments = argName;
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
using (Process process = Process.Start(start))
{
using (StreamReader reader = process.StandardOutput)
{
string result = reader.ReadToEnd();
textoutput = result;
}
}
return textoutput;
}

How to count the invocation of Webservices deployed on Glassfish 3.1

How to count the invocation of Webservices deployed on Glassfish 3.1?
Actually I can get what I want at console commands? as following
asadmin get -m "server.applications.hello-jaxws2*" server.applications.hello-jaxws2.2.server.Hello.requestcount-count = 14
But I want to know if there is a way of getting the invocation count of web services programatically?
As an example using Glassfish 3.1.2. and a Web service named "NewWebService" here is a code extract that retrieves the number of requests for that Web service.
public static void showRequestCount(MBeanServerConnection mbs) throws Exception {
ObjectName on = new ObjectName("amx:pp=/mon/server-mon[server],type=servlet-instance-mon,name=WebApplication1/server/NewWebService");
final Set<ObjectInstance> mBeans = mbs.queryMBeans(on, null);
for (ObjectInstance mbean : mBeans) {
System.out.println("mbean: " + mbean);
final MBeanInfo info = mbs.getMBeanInfo(on);
final MBeanAttributeInfo[] attributes = info.getAttributes();
for (int i = 0; i < attributes.length; i++) {
MBeanAttributeInfo mBeanAttributeInfo = attributes[i];
if (mBeanAttributeInfo.getName().equals("requestcount")) {
final Object attribute = mbs.getAttribute(on, mBeanAttributeInfo.getName());
CompositeDataSupport cds = (CompositeDataSupport) attribute;
final Object requestCount = cds.get("count");
System.out.println("Object name: " + on.getKeyProperty("name"));
System.out.println("Request count: " + requestCount);
}
}
}
}
The result is:
mbean: servlet-instance-mon[amx:pp=/mon/server-mon[server],type=servlet-instance-mon,name=WebApplication1/server/NewWebService]
Object name: WebApplication1/server/NewWebService
Request count: 18
Please note that the ObjectName of the MBean and/or its attributes may vary depending on your Glassfish version.

Why does SQL Server CLR procedure hang in GetResponse() call to web service

Environment: C#, .Net 3.5, Sql Server 2005
I have a method that works in a stand-alone C# console application project. It creates an XMLElement from data in the database and uses a private method to send it to a web service on our local network. When run from VS in this test project, it runs in < 5 seconds.
I copied the class into a CLR project, built it, and installed it in SQL Server (WITH PERMISSION_SET = EXTERNAL_ACCESS). The only difference is the SqlContext.Pipe.Send() calls that I added for debugging.
I am testing it by using an EXECUTE command one stored procedure (in the CLR) from an SSMS query window. It never returns. When I stop execution of the call after a minute, the last thing displayed is "Calling GetResponse() using http://servername:53694/odata.svc/Customers/". Any ideas as to why the GetResponse() call doesn't return when executing within SQL Server?
private static string SendPost(XElement entry, SqlString url, SqlString entityName)
{
// Send the HTTP request
string serviceURL = url.ToString() + entityName.ToString() + "/";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(serviceURL);
request.Method = "POST";
request.Accept = "application/atom+xml,application/xml";
request.ContentType = "application/atom+xml";
request.Timeout = 20000;
request.Proxy = null;
using (var writer = XmlWriter.Create(request.GetRequestStream()))
{
entry.WriteTo(writer);
}
try
{
SqlContext.Pipe.Send("Calling GetResponse() using " + request.RequestUri);
WebResponse response = request.GetResponse();
SqlContext.Pipe.Send("Back from GetResponse()");
/*
string feedData = string.Empty;
Stream stream = response.GetResponseStream();
using (StreamReader streamReader = new StreamReader(stream))
{
feedData = streamReader.ReadToEnd();
}
*/
HttpStatusCode StatusCode = ((HttpWebResponse)response).StatusCode;
response.Close();
if (StatusCode == HttpStatusCode.Created /* 201 */ )
{
return "Created # Location= " + response.Headers["Location"];
}
return "Creation failed; StatusCode=" + StatusCode.ToString();
}
catch (WebException ex)
{
return ex.Message.ToString();
}
finally
{
if (request != null)
request.Abort();
}
}
The problem turned out to be the creation of the request content from the XML. The original:
using (var writer = XmlWriter.Create(request.GetRequestStream()))
{
entry.WriteTo(writer);
}
The working replacement:
using (Stream requestStream = request.GetRequestStream())
{
using (var writer = XmlWriter.Create(requestStream))
{
entry.WriteTo(writer);
}
}
You need to dispose the WebResponse. Otherwise, after a few calls it goes to timeout.
You are asking for trouble doing this in the CLR. And you say you are calling this from a trigger? This belongs in the application tier.
Stuff like this is why when the CLR functionality came out, DBAs were very concerned about how it would be misused.

WMI Remote connection

I have an issue regarding WMI connection through asp.net from Computer A (windows 2003 server) to Computer B (Windows XP)..
The error is as follows:
RPC server is unavailable..
There are a few steps that you must take in order to successfully leverage WMI connectivity. The basics are you must allow remote management on the target box of course. If you can’t RDP into it, chances are, you can’t remote manage anything else. This can also include Windows firewall issues too. Make sure your request can even get in at all.
Next, start simple. Can you even poll for the running processes on that box? Try to output all the running processes on the target box with System.Diagnostics.Process currentProcess = System.Diagnostics.Process.GetProcesses("machine-name"). If you can at least get some information on the box then the RPC message you are getting has to do with incorrect arguments being passed in, perhaps?
Anyways, I recently wrote a web application that allowed the users to find a server on the LAN and kill a target process there or start a new one. I did it in C# so the code snippet below is just what I used. It's not the best but its working in production right now:
public static class RemoteProcessAccess
{
public static void KillProcessByProcessID(string NameOfServer, string DomainName, string LogIn, string Password, int processID)
{
//#1 The vars for this static method
#region /// <variables> ...
string userName;
string password;
string machineName;
string myDomain;
Hashtable hs = new Hashtable();
ManagementScope mScope;
ConnectionOptions cnOptions;
ManagementObjectSearcher objSearcher;
ManagementOperationObserver opsObserver;
ManagementClass manageClass;
DirectoryEntry entry;
DirectorySearcher searcher;
DirectorySearcher userSearcher;
#endregion
//#2 Set the basics sent into the method
machineName = NameOfServer;
myDomain = DomainName;
userName = LogIn;
password = Password;
cnOptions = new ConnectionOptions();
cnOptions.Impersonation = ImpersonationLevel.Impersonate;
cnOptions.EnablePrivileges = true;
cnOptions.Username = myDomain + "\\" + userName;
cnOptions.Password = password;
mScope = new ManagementScope(#"\\" + machineName + #"\ROOT\CIMV2", cnOptions);
//#3 Begin Connection to Remote Box
mScope.Connect();
objSearcher = new ManagementObjectSearcher(String.Format("Select * from Win32_Process Where ProcessID = {0}", processID));
opsObserver = new ManagementOperationObserver();
objSearcher.Scope = mScope;
string[] sep = { "\n", "\t" };
//#4 Loop through
foreach (ManagementObject obj in objSearcher.Get())
{
string caption = obj.GetText(TextFormat.Mof);
string[] split = caption.Split(sep, StringSplitOptions.RemoveEmptyEntries);
// Iterate through the splitter
for (int i = 0; i < split.Length; i++)
{
if (split[i].Split('=').Length > 1)
{
string[] procDetails = split[i].Split('=');
procDetails[1] = procDetails[1].Replace(#"""", "");
procDetails[1] = procDetails[1].Replace(';', ' ');
switch (procDetails[0].Trim().ToLower())
{
//You could look for any of the properties here and do something else,
case "processid":
int tmpProc = Convert.ToInt32(procDetails[1].ToString());
//if the process id equals the one passed in....
//(this is redundant since we should have limited the return
//by the query where above, but we're paranoid here
if (tmpProc.Equals(processID))
{
obj.InvokeMethod(opsObserver, "Terminate", null);
}
break;
}//end process ID switch...
}//end our if statement...
}//end our for loop...
}//end our for each loop...
}//end static method
}
Look at KB875605 ("How to troubleshoot WMI-related issues in Windows XP SP2")
You could enable the RPC server on any target machine by running this on the target's command prompt:
[/code]
netsh firewall set service RemoteAdmin
[/code]
Worked for me at least. :)
Try to use wmic command line to get information from the remote computer, also you can install the code of Services+ and try to connect and debug your connection to the server, most likely it is firewall problem or RPC services is down or disabled.
