tWebservice: Nullpointer exception

[Anonymous]

Hi all,

the problem described here https://community.talend.com/t5/Design-and-Development/resolved-tWebservice-nullpointer-exception/td... is not solved for me at all. I'm still getting a nullpointer exception when I try to run the talend example job for the tWebservice component.

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)

Like suggested in previous posts, I switched to Java JDK 6 (u45) with no improvements (same error). I'm using talend open studio 6.4.0 on Windows 10.

Could you please help!

Kind regards

Okay, this is how I configured ther tWebservice component:

Overall Job and Java config:

And again the error log:

Exception in component tWebService_1
java.lang.NullPointerException
	at org.apache.cxf.common.util.Compiler.useJava6Compiler(Compiler.java:187)
	at org.apache.cxf.common.util.Compiler.compileFiles(Compiler.java:141)
	at org.apache.cxf.common.util.Compiler.compileFiles(Compiler.java:136)
	at org.apache.cxf.endpoint.dynamic.DynamicClientFactory.compileJavaSrc(DynamicClientFactory.java:611)
	at org.apache.cxf.endpoint.dynamic.DynamicClientFactory.createClient(DynamicClientFactory.java:370)
...

Like you can see in screenshots above I switched back to JDK 1.8.0_131.

So, what is the matter with tWebService? Any ideas?

BTW: When you mark the tWebservice component and press F1 you can see the help page with an example related to that component. I tried the example step by step in talend di (Commercial Version!) and facing the same error. How can that be? talend please fix that bug!

Hi TalendDIUser

I have tested the scenario Getting country names trhrough a web service in the component document and it works. Below is my JRE configuration in preferences page.

As I suggested, have a try to copy the jar file tools.jar from <jdk installation dir>/lib to <jre installation dir>/lib, let me know if it works.

So everybody: Just copy the tools.jar file from jdk to jre lib folder like shong suggested!
