Webservice Model Execution error :Weddynpro JAVA

[Former Member]

Hi All,

I have developed a weddynpro Application which invokes one webservice from DB based on certain Action.

All the necessary model connections are established and was able to execute the Webservice initially.

Atleat now, we are facing the following exception while trying to execute the Model from UI. Still it works good in WS Navigator.

Exception :

Connection IO Exception. Check nested exception for details. (Parameter set failure. The runtime was not able to set some parameter value. See nested exception for details.).
[EXCEPTION]

One of the fields datatype maintained in Model service is Big Integer. But the Model Reference in Component Controller shows Decimal.

Already undeployed the DCs and re-deployed it. But still no luck. Kindly give your suggestion.

Hi All,

The problem is with one of the Fields Data type change at Service Level.

Reverting the changes back to the String Field type resolved this issue.

Thanks all for your replies.

Hi,

This seems the problem with the empty value you are passing in one of the input parameter of the Web Service.

Pass 0 in the Decimal input field and check. This must resolve your issue.

Check this thread it resembles the same problem which you are getting.

Web service call error due to misformed answer

You might be getting this error due to some problem in the out put of the webservice.

Check wether any parameter that is returning in the output of the webservice is null or empty.

Hope this is helpful !!!

As Jun and Sharath have said, the easiest and probably quickest solution is to restart your runtime system.  SAP managed to resolve caching of metadata issues with RFC models but WS still have this problem.

At least if you restart the system you will know for sure whether it is a caching issue (the problem will have gone away) or something else (you still have the problem, and need more investigation.)

Try the option suggested by Jun.

It seems like the classic case of mis-match in the metadata in your local server and actual web service.
