How to solve NoSuchMethodError when i'm calling webservice from workflow?

Hello,

i'm trying upload file through webservice client but i m getting this error:

I suspect that there is conflict between org.apache.commons.schema.XmlSchema that is include in alfresco-repository:5.1.e.jar and org.apache.ws.xmlschema.xmlschema-core which i'm using in my webservice client.

Could you give me some advices how to solve this problem. If i run the client it works. but if i call client from workflow service task, i'm getting NoSuchMethodError.

Thank you so much for any help.

Hi ,

Apparently there's a conflict of library versions and some method cannot be found in the classpath. Are you able to make sure that you're using the same version of the library in your client?

Thanks,

Hi ‌

Thank you for your answer, yep i'm sure the versions from client are the same. Last time i ve tried to use activiti-cxf 5.20.0 instead of just org.apache.cxf but i still get the same error. Any ideas what may cause the conflict?

Thank you

HI ,

I would need to reproduce this in a very simple unit test to answer you. Would you mind describing your implementation scenario/use case? The best is you can send over a unit test.

Thanks,

Thong

Hi Thong Huynh‌

It's very simple use case. I'm trying to call webservice from workflow. There is one userTask and one serviceTask in workflow. Service task is calling java class where is implemented call to our webservice. When I'm trying call webservice from some main class just like a java class its work. When i try to call ws from service Task i get this error. I try to solve it just localy with embedded tomcat server from alfresco-sdk-parent. Alfresco version is 5.1.e, activiti-cxf version 5.19.0.1 and org.apache.httpcomponents.httpcore version 4.4.5, those are external libraries i'm using.

Is it enough to test it for you?

Thank you for your answer

Hi Thong Huynh,

Sorry I wasn't specific. Our webservice works, if im try it in browser or if i'm calling ws from console with client. But in alfresco context it does not work. There is problem with javax.xml.ws.Service class. In our ws classloader takes it from default jdk but in alfresco context it takes this class from geronimo-jaxws_2.1_spec-1.0.jar

Thank you for any advices.

alfresco context

Are you referring to Alfresco ECM or Alfresco BPM (Activiti) ?

Thanks

Hi ‌

I'm reffering to Alfresco BPM (Activiti)

Thanks

Hi Jakub Rautner ,

I'm a bit confused. You said it works fine for you so I thought you were able to call web service successfully in Activiti context.

There's nothing I can do to help you unless you can share a unit test that demonstrates this issue. In your unit test, it needs to demonstrate how web service is called and the fact that geronimo-jaxws_2.1_spec-1.0.jar is being used.

I believe it is a basic programming task to solve library conflict issue like this. This issue seems not a problem with Activiti but rather a problem with how you implement your web service call in your process.

Hope I make sense,

Thanks,

Thong Huynh
