I have written an ASP.NET web service.
It looks like this:
WebServices.logic pLogic = new WebServices.logic();
WebServices.manager[] pManager = new PowerManager[1];
pManager[0] = new PowerManager();
pManager[0].CustomerId = "sjsjshd";
pManager[0].state = pLogic.getState("sasj");
return pManager[0];
The pManager class looks like this:
public string _CustomerId;
public int PowerStatus;
public List<ArrayList> _Power;
public string CustomerId
{
get
{
return _CustomerId;
}
set
{
_CustomerId = value;
}
}
public List<ArrayList> Power
{
get
{
return _Power;
}
set
{
_Power = value;
}
}
When I run it, I get a repetition of the results, like so:
<p>
<_CustomerId>sjsjshd</_CustomerId>
<pStatus>0</PowerStatus>
−
<_p>
−
<ArrayOfAnyType>
<anyType xsi:type="xsd:int">1</anyType>
</ArrayOfAnyType>
<ArrayOfAnyType/>
</_p>
<CustomerId>sjsjshd</CustomerId>
−
<p>
−
<ArrayOfAnyType>
<anyType xsi:type="xsd:int">1</anyType>
</ArrayOfAnyType>
<ArrayOfAnyType/>
</p>
</pManager>
However, there is no duplicate values stored (Eg. I store client name in a collection, but only once - count of 1). There are no duplicates stored when I call getState(). This method returns a collection and it contains one value, but the results in XML has a repetition of this.
How comes the results appear to repeat themselves? When running the system, I only get one error.
Thanks
OK, looks like your XML serialization is giving you all the public members of your PowerManager class. Based on the naming convention of starting with an underscore, those members should be private, like this:
private string _CustomerId;
private List<ArrayList> _Power;
You also state "When running the system, I only get one error." What error are you getting?

I have a tsv file which has fixed rows but each row is mapped to different Java Class.
For example.
recordType recordValue1
recordType recordValue1 recordValue2
for First row I have follofing class:
public class FirstRow implements ItsvRecord {
#Parsed(index = 0)
private String recordType;
#Parsed(index = 1)
private String recordValue1;
public FirstRow() {
}
}
and for second row I have:
public class SecondRow implements ItsvRecord {
#Parsed(index = 0)
private String recordType;
#Parsed(index = 1)
private String recordValue1;
public SecondRow() {
}
}
I want to parse the TSV file directly to the respective objects but I am falling short of ideas.
Use an InputValueSwitch. This will match a value in a particular column of each row to determine what RowProcessor to use. Example:
Create two (or more) processors for each type of record you need to process:
final BeanListProcessor<FirstRow> firstProcessor = new BeanListProcessor<FirstRow>(FirstRow.class);
final BeanListProcessor<SecondRow> secondProcessor = new BeanListProcessor<SecondRow>(SecondRow.class);
Create an InputValueSwitch:
//0 means that the first column of each row has a value that
//identifies what is the type of record you are dealing with
InputValueSwitch valueSwitch = new InputValueSwitch(0);
//assigns the first processor to rows whose first column contain the 'firstRowType' value
valueSwitch.addSwitchForValue("firstRowType", firstProcessor);
//assigns the second processor to rows whose first column contain the 'secondRowType' value
valueSwitch.addSwitchForValue("secondRowType", secondProcessor);
Parse as usual:
TsvParserSettings settings = new TsvParserSettings(); //configure...
// your row processor is the switch
settings.setProcessor(valueSwitch);
TsvParser parser = new TsvParser(settings);
Reader input = new StringReader(""+
"firstRowType\trecordValue1\n" +
"secondRowType\trecordValue1\trecordValue2");
parser.parse(input);
Get the parsed objects from your processors:
List<FirstRow> firstTypeObjects = firstProcessor.getBeans();
List<SecondRow> secondTypeObjects = secondProcessor.getBeans();
The output will be*:
[FirstRow{recordType='firstRowType', recordValue1='recordValue1'}]
[SecondRow{recordType='secondRowType', recordValue1='recordValue1', recordValue2='recordValue2'}]
Assuming you have a sane toString() implemented in your classes
If you want to manage associations among the objects that are parsed:
If your FirstRow should contain the elements parsed for records of type SecondRow, simply override the rowProcessorSwitched method:
InputValueSwitch valueSwitch = new InputValueSwitch(0) {
#Override
public void rowProcessorSwitched(RowProcessor from, RowProcessor to) {
if (from == secondProcessor) {
List<FirstRow> firstRows = firstProcessor.getBeans();
FirstRow mostRecentRow = firstRows.get(firstRows.size() - 1);
mostRecentRow.addRowsOfOtherType(secondProcessor.getBeans());
secondProcessor.getBeans().clear();
}
}
};
The above assumes your FirstRow class has a addRowsOfOtherType method that takes a list of SecondRow as parameter.
And that's it!
You can even mix and match other types of RowProcessor. There's another example here that demonstrates this.
Hope this helps.
Is there a way of dynamically building a cypher query using spring data neo4j?
I have a cypher query that filters my entities similar to this one:
#Query("MATCH (n:Product) WHERE n.name IN {0} return n")
findProductsWithNames(List<String> names);
#Query("MATCH (n:Product) return n")
findProductsWithNames();
When the names list is empty or null i just want to return all products. Therefore my service impl. checks the names array and calls the correct repository method. The given example is looks clean but it really gets ugly once the cypher statements are more complex and the code starts to repeat itself.
You can create your own dynamic Cypher queries and use Neo4jOperations to execute them. Here is it an example (with a query different from your OP) that I think can ilustrate how to do that:
#Autowired
Neo4jOperations template;
public User findBySocialUser(String providerId, String providerUserId) {
String query = "MATCH (n:SocialUser{providerId:{providerId}, providerUserId:{providerUserId}})<-[:HAS]-(user) RETURN user";
final Map<String, Object> paramsMap = ImmutableMap.<String, Object>builder().
put("providerId", providerId).
put("providerUserId", providerUserId).
build();
Map<String, Object> result = template.query(query, paramsMap).singleOrNull();
return (result == null) ? null : (User) template.getDefaultConverter().convert(result.get("user"), User.class);
}
Hope it helps
Handling paging is also possible this way:
#Test
#SuppressWarnings("unchecked")
public void testQueryBuilding() {
String query = "MATCH (n:Product) return n";
Result<Map<String, Object>> result = neo4jTemplate.query(query, Collections.emptyMap());
for (Map<String, Object> r : result.slice(1, 3)) {
Product product = (Product) neo4jTemplate.getDefaultConverter().convert(r.get("n"), Product.class);
System.out.println(product.getUuid());
}
}
I have created a class and published it as web service. I have created a web method like this:
public void addNewRow(MyObject cob) {
MyAppModule myAppModule = new MyAppModule();
try {
ViewObjectImpl vo = myAppModule.getMyVewObject1();
================> vo object is now null
Row r = vo.createRow();
r.setAttribute("Param1", cob.getParam1());
r.setAttribute("Param2", cob.getParam2());
vo.executeQuery();
getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
}
}
As I have written in code, myAppModule.getMyVewObject1() returns a null object. I do not understand why! As far as I know AppModule has to initialize the object by itself when I call "getMyVewObject1()" but maybe I am wrong, or maybe this is not the way it should be for web methods. Has anyone ever faced this issue? Any help would be very appreciated.
You can check nice tutorial: Building and Using Web Services with JDeveloper
It gives you general idea about how you should build your webservices with ADF.
Another approach is when you need to call existing Application Module from some bean that doesn't have needed environment (servlet, etc), then you can initialize it like this:
String appModuleName = "org.my.package.name.model.AppModule";
String appModuleConfig = "AppModuleLocal";
ApplicationModule am = Configuration.createRootApplicationModule(appModuleName, appModuleConfig);
Don't forget to release it:
Configuration.releaseRootApplicationModule(am, true);
And why you shouldn't really do it like this.
And even more...
Better aproach is to get access to binding layer and do call from there.
Here is a nice article.
Per Our PM : If you don't use it in the context of an ADF application then the following code should be used (sample code is from a project I am involved in). Note the release of the AM at the end of the request
#WebService(serviceName = "LightViewerSoapService")
public class LightViewerSoapService {
private final String amDef = " oracle.demo.lightbox.model.viewer.soap.services.LightBoxViewerService";
private final String config = "LightBoxViewerServiceLocal";
LightBoxViewerServiceImpl service;
public LightViewerSoapService() {
super();
}
#WebMethod
public List<Presentations> getAllUserPresentations(#WebParam(name = "userId") Long userId){
ArrayList<Presentations> al = new ArrayList<Presentations>();
service = (LightBoxViewerServiceImpl)getApplicationModule(amDef,config);
ViewObject vo = service.findViewObject("UserOwnedPresentations");
VariableValueManager vm = vo.ensureVariableManager();
vm.setVariableValue("userIdVariable", userId.toString());
vo.applyViewCriteria(vo.getViewCriteriaManager().getViewCriteria("byUserIdViewCriteria"));
Row rw = vo.first();
if(rw != null){
Presentations p = createPresentationFromRow(rw);
al.add(p);
while(vo.hasNext()){
rw = vo.next();
p = createPresentationFromRow(rw);
al.add(p);
}
}
releaseAm((ApplicationModule)service);
return al;
}

I have insert some node into Neo4j DB.And I want to select some node from database and cast it to specific class.
Here are some code about the problem:
class Service {
Neo4jTemplate neo4jTemplate
#Transactional
def find() {
def id1 = 11
//Knowledge k = neo4jTemplate.findOne(1, Knowledge)
Result result = neo4jTemplate.query("start n=node(11) return ID(n),n.name,n.age;", null)
//how to cast the result to User class
println "the tpye of result called User is "+ result.to(User.class).is(cn.edu.bnuz.itc.bok.sub2.User.class)
}
}
The detail about node like :
+-------------------------------------------------------------------------+
| Node[11]{career:"programmer",name:"kelvin",age:35,introduce:"lazy doy"} |
+-------------------------------------------------------------------------+
#NodeEntity
class User {
#GraphId
Long id;
String name;
int age;
}
I just want get the node's id, name, age from db and put it into a User class.
But it failed many time with many method.
Here I have encounter a problem which is :How can I cast the result to my target class? I have try many method to cast but fail finally.Thank you for you attention.
Return the user node from the query and call the to method of the returned Result with the desired class as argument:
Result result = neo4jTemplate.query("start n=node(11) return n", null);
for(User u : result.to(User.class)) {
doSomethingWith(u);
}
You may want to consider using repositories that support cypher queries like:
public interface UserRepository extends GraphRepository<User> {
#Query("start n=node(11) return n")
Iterable<User> getUser11();
}
Currently, I'm using Conversion Studio to bring in a CSV file and store the contents in an AX table. This part is working. I have a block defined and the fields are correctly mapped.
The CSV file contains several comments columns, such as Comments-1, Comments-2, etc. There are a fixed number of these. The public comments are labeled as Comments-1...5, and the private comments are labeled as Private-Comment-1...5.
The desired result would be to bring the data into the AX table (as is currently working) and either concatenate the comment fields or store them as separate comments into the DocuRef table as internal or external notes.
Would it not require just setting up a new block in the Conversion Studio project that I already have setup? Can you point me to a resource that maybe shows a similar procedure or how to do this?
Thanks in advance!
After chasing the rabbit down the deepest of rabbit holes, I discovered that the easiest way to do this is like so:
Override the onEntityCommit method of your Document Handler (that extends AppDataDocumentHandler), like so:
AppEntityAction onEntityCommit(AppDocumentBlock documentBlock, AppBlock fromBlock, AppEntity toEntity)
{
AppEntityAction ret;
int64 recId; // Should point to the record currently being imported into CMCTRS
;
ret = super(documentBlock, fromBlock, toEntity);
recId = toEntity.getRecord().recId;
// Do whatever you need to do with the recId now
return ret;
}
Here is my method to insert the notes, in case you need that too:
private static boolean insertNote(RefTableId _tableId, int64 _docuRefId, str _note, str _name, boolean _isPublic)
{
DocuRef docuRef;
boolean insertResult = false;
;
if (_docuRefId)
{
try
{
docuRef.clear();
ttsbegin;
docuRef.RefCompanyId = curext();
docuRef.RefTableId = _tableId;
docuRef.RefRecId = _docuRefId;
docuRef.TypeId = 'Note';
docuRef.Name = _name;
docuRef.Notes = _note;
docuRef.Restriction = (_isPublic) ? DocuRestriction::External : DocuRestriction::Internal;
docuRef.insert();
ttscommit;
insertResult = true;
}
catch
{
ttsabort;
error("Could not insert " + ((_isPublic) ? "public" : "private") + " comment:\n\n\t\"" + _note + "\"");
}
}
return insertResult;
}
