response web service return null

carlosrp — Wed, 25 Feb 2015 13:40:40 GMT

Hi, I have tried to create a Hello world with activities where you consume a web service, took a week doing this and finally today I could consume the web service but the value that returned was null and I don't know why.This example is very short, you will not take much time to help meI don't speak

According to your WSDL file I think you have a method like that in your WS:
<java>
@WebResult
String sayHi(@WebParam String name);
</java>
You have 2 options to solve it:
Option1:
just use @WebResult with a specific name for your result and adjust the bpmn20.xml file to have the correct mapping.
<java>
@WebResult(name="niceName")
String sayHi(@WebParam String name);
</java>

Option2: Adjust your bpmn20.xml file to map correctly to the jaxb-xjc generated property.
<code>
    <itemDefinition id="_return" structureRef="string" />
…

       <dataOutputAssociation>
                <sourceRef>_return</sourceRef>
                <targetRef>greet</targetRef>
       </dataOutputAssociation>
</code>

The problems come from the fact that "return" is a keyword in java and because of that a safe property "_return" is generated by JAXB-XJC Schema-to-Java compiler.
for details see: jaxb-xjc:2.1.7 library : com.sun.tools.xjc.model.CPropertyInfo.java line:122

your solution is correct, now works correctly, thank you very much, now my unit tests run fine, but i am having trouble importing my process in ActivitiExplorer, I am using activiti 5.17.0 and i added the library activiti-cxf-5.17.0.jar in the activiti-explorer \ WEB-INF \ lib directory, and does not work. Can you help me?

Do you have any errors in the log ?
please provide some more details and a more detailed way to reproduce it (step by step)

Re: response web service return null

carlosrp — Mon, 23 Mar 2015 15:22:57 GMT

When I try to deploy my process in Activiti-Explorer, it displays the following error log:
{I think it's a dependency problem, but do not know what .jar add}

Re: response web service return null

carlosrp — Mon, 23 Mar 2015 15:33:10 GMT

Sorry, I forgot to mention that i tried to deploy my process in ActivitiExplorer after copy "activiti-cxf-5.17.0.jar" in "activiti-explorer \ WEB-INF \ lib"

Re: response web service return null

vasile_dirla — Mon, 23 Mar 2015 21:55:46 GMT

As you can see in your log:
"Caused by: java.lang.ClassNotFoundException: com.sun.tools.xjc.api.ErrorListener"
so you need that class into your class loader.
this class could be found in: jaxb-xjc-2.1.7.jar (so you have to be sure is part of your class path)
but pay attention.. it's possible after you'll add this jar into your class path to need some other jars. (read your stacktrace and then you'll see what is necessary to do)

Re: response web service return null

carlosrp — Tue, 24 Mar 2015 13:14:34 GMT

I added the jaxb-impl-2.1.7.jar and jaxb-xjc-2.1.7.jar in "activiti-explorer\WEB-INF\lib\"and i have now the following error:
{

Re: response web service return null

trademak — Thu, 26 Mar 2015 07:57:24 GMT

If you look at our activiti-cxf module you can see all the dependencies listed there.
The error message is again obvious as you are missing the wsdl4j JAR.

Best regards,

Re: response web service return null

Im guessing something is wrong with the process. Don't you see any logging about the process parsing failing before that?

Re: response web service return null

carlosrp — Tue, 31 Mar 2015 13:25:49 GMT

You are correct jbarrez, I have the following log, which seems a dependency problem, but I added all dependencies of cxf-module.
These are all added dependencies:
