XI AF API call failed. Module exception: Java Mapping

[nabendu_sen]

Hi Experts,

I have faced a typical error for one of my interface. The Scenario is SOAP to SOAP and we are performing SOAP Lookup before sending the data to Target web service. We are using one Java Mapping 'FileIns_lookupLoad.java --- com/fi/' and performing the SOAP Lookup from within the code. In the Lookup Communication channel we are using 'Axis' as message protocol and passing couple of values through Module Key parameters. We have same ESR and ID objects in Development, Quality and Production (as per Version ID and History).

Now the problem is Lookup is failing only in Development but Quality and Production is working fine. I have replaced Quality CC URL with the development WSDL URL, but that worked fine. That means Development Web Service is good. We are getting the below error in Dev:

<SAP:Stack>StreamTransformationException triggered by application mapping program com/fi/FileIns_lookupLoad; Look Up Failed</SAP:Stack>

I have already checked with Basis and as per them JDK and Java versions are identical in Dev, QAS and Prod. It seems something is wrong with 'XI AF API' which we are calling from the channel. If we totally ignore Lookup process and send direct data, it is working fine. Target CC is also using Axis.

Sequence in CC: afreq ->xireq ->wssec2 ->xires ->afres

For any more information please let me know.

Thanks,

Hi Nabendu,

were you able to solve this problem? We are facing the same on PI 7.11 SP4 in our landscape.

Best regards,

Markus

Hi Markus,

What I can remember that was some issue with the Axis Adapter deployed in PI. So we redeployed and it got resolved.

Thanks,

Nabendu.

[markus_schalk]

Hi Nabendu,

thanks a lot for your response. We couldn't solve it so far, but we'll try to redeploy the Axis Adapter then.

Again, thank for your help!

Hi Markus,

Did you fix this issue?

[markus_schalk]

Dear Jaime,

redeployment solved our problem. Hope this helps you as well!

Tanks for you Replay Markus,

Just to be sure, what kind of deploy did you use, the this one 

or the XI 3RD PARTY SCA?

Hi,

I have same issue when I am trying do a soap lookup from message mapping. We needed to use SOAP-AXIS adapter (WSSE enabled service)to do a webservice call and get a lookup values.

When I run the receiver lookup channels with a dummy interface it works,but when same payload been request been called through lookup UDF ,I am getting the same error like the original poster.

Webservice call works good with SOAP UI tool too with the same payload I am sending in Lookup UDF and dummy interface using lookup channel as receiver channel.

we already deployed Apache frame work libraries ,all in mandatory components and 2 (xmlsec-1.4.2.jar,wss4j-1.5.4.jar) from optional components.

Please let me know,how you guys able to resolve the issue or first of does SOAP AXIS support lookups with regular SOAP lookup API?we are on 7.50 AEX SP00.

Dear Jaime,

we used SAP Note 1028961 - How to prepare axisproviderlib.sda for Adapter Framework

and also used SAPXI3RDPARTY.SCA to build the SDA.

Hi Experts,

Any help would be really appreciated.

Thanks,

Hi Nabendu,

Is the java coding same in dev,quality,acceptance and production? If they are same, well, then except java version mismatch, I cannot think of anything else.

In case you have a different code in development then look at the parts where you might be converting from bytes to String and vice-versa. This conversion sometimes throws StreamTransformationException.

Hi Anupam,

The Java Mapping code is same in Dev , QAS and Prod. Also the versions of the JAR is same.

Please find the code below.

Hi Nabendu,

The code you have pasted in forum is not complete or not being displayed properly. Still I have a doubt look at this line

trace.addInfo(lookUpRequest); 

lookUpRequest object has not been initialised. I could not find its declaration also.

Secondly I think you need to debug the code i.e. add more trace and try statements to get the values, or get values for some variables by running in production or quality.

For example

try { 
channel = LookupService.getChannel(inParamBusService, inParamChannel);
 trace.addInfo(channel.toString()); 
}
catch(Exception e)
{
      //get the exact error in trace
        trace.addInfo(e.getMessage());
     // in development assign values you received from production, this you get from trace and hardcode it in development
    // channel= value received from production using LookupService.getChannel(inParamBusService, inParamChannel);
}

You need to do this for all lines important for connection, so that you know exact cause of error.

Only with debugging you can try to know exact cause.

Hope this helps.

regards

Anupam
