[resolved] tWebservice - nullpointer exception

Anonymous — Wed, 15 May 2013 08:47:47 GMT

I'm trying to add a category via webservice to virtuemart.
I receive the following error:
Exception in component tWebService_1
java.lang.NullPointerException
at org.apache.cxf.common.util.Compiler.useJava6Compiler(Compiler.java:190)
at org.apache.cxf.common.util.Compiler.compileFiles(Compiler.java:144)
at org.apache.cxf.common.util.Compiler.compileFiles(Compiler.java:139)
I'm not able to debug this error (or I don't know how).

My job looks like the following pictures:
any ideas?
Thank you!
Regards,
Robert

Hi,
Is there any compile error in "Code" field? From the error info, it seems that the setting of tWebservice component is not correct.
Best regards

Hi Sabrina,
Thank you very much for your answer!
Can you help me - what did you mean with: "compile error in "Code" field"
What can I do?
thx!

Hi.
We usually open the code tab and see if there has compile error. If the job has compile error, you are always required to fix the error before executing the job. The compile error in code tab can point where and what the error is.
See my screenshot

thank you for your explanation!
No there are no errors. It seems to be fine.
I tried to switch to tWebserviceInput - this works (disadvantage is I have to define all columns or I get a nillable exception)

Trying to investigate a little bit, the error seems to come from
ServiceInvokerHelper.invoke() line 235
=>Client client = getClient(serviceName, portName);
=>
protected Client createClient(QName service, QName port) {
// bug 8674
Client client = dynamicClientFactory.createClient(serviceDiscoveryHelper.getLocalWsdlUri(), service, Thread
.currentThread().getContextClassLoader(), port, bindingFiles);
// end
HTTPConduit conduit = (HTTPConduit) client.getConduit();
if (configuration != null) {
configuration.configureHttpConduit(conduit);
}
return client;
}
any other ideas?
Thank you!
regards,
robert

For everybody - I found it!
https://jira.talendforge.org/browse/TDI-25565 (Talend DI / TDI-25565)
The tWebservice components requires a JDK to work. Please select a JDK java.exe in the Preferences/Talend/Java interpreter in the studio.

Does it work with java7?
I am running Windows 7/b4bit, and the java interpreter is set as C:\Program Files\Java\jre7\bin\java.exe, and I am still getting the NullPointer exception

Hi,
For win7/64 bit, you'd better use java 6. Is it working in java 6 for your case?

Using JDK1.6 gets rid of the NullPointer exception.
Now I have the following exception when trying to use tWebService to call a HTTPS web service developed with Microsoft WCF with user/password authentication.
Thanks

Can it not work with jre6 ??

Hi sansri,
You'd better install compatible JDK instead of JRE only which will probably cause compile error when execute job.

Damn! I've just lost a lot of time troubleshooting this issue...
Sabrina, can you please add this information to the installation manual ("Please select a JDK java.exe in the Preferences/Talend/Java interpreter in the studio")?

In my opinion, its weired behavior - use a JRE instead of installed JDK (by default).
It's easier for user to just forget to select appropriate Java variant and waste a lot of time - trying to understand "what's wrong with a (for example) tWebService's configuration which he (she) just made...", while the trouble is not in a component configuration at all.

Sabrina, can you please add a feature request for JDK auto-detection, or detection of all available JRE/JDK instances and asking user which of them the talend should use?
