Is it possible to call asynchronous Web Service using Adaptive WS model?

[Former Member]

Hello,

I was trying to call asynchronous web service and after execution exception has arised

java.lang.NullPointerException

at com.sap.tc.webdynpro.model.webservice.model.WSGenericModelClassExecutable.fillOutputParametersToMc(WSGenericModelClassExecutable.java:281)

at com.sap.tc.webdynpro.model.webservice.model.WSGenericModelClassExecutable.execute(WSGenericModelClassExecutable.java:93)

at com.sap.tc.webdynpro.model.webservice.gci.WSTypedModelClassExecutable.execute(WSTypedModelClassExecutable.java:46)

at at.gov.bmf.demo.comp.employee.EmployeeDemo.ok(EmployeeDemo.java:242)

at at.gov.bmf.demo.comp.employee.wdp.InternalEmployeeDemo.ok(InternalEmployeeDemo.java:285)

I have NWDS 7.0.

How can I set model, to avoid binding web service response to model?

Thanks.

Web Services can be used not only for integration among applications, data, and services, but they can also support an asynchronous communication model.

Sorry,

but rather I would like to know how to consume asynchronous Web Service in Web DynPro.

I just ran into this issue, same exact problem.

The quick and dirty workaround I did, after trying out several other things to make sure I didn't do anything wrong to cause this problem, was to just catch the nullpointer, and then go along my merry way.

try{

query.execute();

}

catch(NullPointerException e){

//we get a worthless error here from Webdynpro, so we just ignore it. Not pretty. But unavoidable

}

If someone else has any other solution, I would love to hear them.

This is on NW7.0 SP15
