Hi I got EXCEPTION_DURING_EXECUTE in RWB->Message Monitoring

[Former Member]

Hi

I am doing a Java Server Proxy scenario. I have given all the parameteres like Sender service, sender namespace,Receiver service,...and

QoS:Exactly Once in Order in RWB->Message Monitoring and i got status: System Error

<b>I have tested in IR->meassage mapping->Test.....tested successfully here.</b>

I have generated java Proxies->Inbound synchronous message interface, and created a EJB and Enterprise modules added EJB module to Enetrprise module, generated ear file---deployed and resgitsred.

<b>In HTTP Client program i got 200 as status code, but in SXMB_MONI and RWB->Message monitoring i got

"EXCEPTION_DURING_EXECUTE"</b>

Ganesh,

<i>RWB->Message Monitoring and i got status: System Error</i>

In RWB, select the message with radio button, select versions button and in the next screen, display MDT for the message version for which there is an error. From this is u will be able to know at which stage of the pipe-line the message is stopped.

<b><i>IR->meassage mapping->Test.....tested successfully here</i></b>

Put the <b>trace level</b> to <b>all</b> and see when the execute method is called.

Hope this helps.

Hi,

>> //Instantiate the response Data type class

>> FoldernameDT_Type instance= new FoldernameDT_Type(); instance.setName(filesavailable);

return instance;

You have to return instance object where you have set the files available list. Try this and check the payload value in SXMB_Moni.

Since you have used same message type for both proxy request and proxy response, its not clear to locate the error.

If u r able to get the file list in the payload, then error should be with Response message mapping.

Hi,

<i>System Error</i>

Check in SMQ2 transaction and check is there any queue is there in this status. If so , check what is the error.

Check this blog-

/people/sap.user72/blog/2005/11/29/xi-how-to-re-process-failed-xi-messages-automatically

Check this Note -871959. This may be useful

<i>In HTTP Client program i got 200 as status code</i>

In SM59 (RFC destinations of Type G) it is success status.

<i>

"EXCEPTION_DURING_EXECUTE</i>

This may be because of your java proxy is unable to read the xml message given from XI.Check is it correct format etc

Hi

I got this in SXMB_MONI->Monitor for processed XML messages->Q.status->Payloads

This is the error i got in top window:

Hi Ganesh,

looks like a mapping error, test your mapping in IR with the payload from SXMB_MONI. You can refer michal's weblog for the same.

Ganesh,

2 points to be noted,

<i>Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XML Declaration not allowed here.(:main:, row:1, col:46</i>

And, in the final payload, you have

<i><?xml version="1.0" encoding="UTF-8" ?>

<?xml version="1.0" encoding="UTF-8" ?></i>

<b>You need to have this declaration occuring only once.</b> Just write this to your Output Stream once ( write it in the START DOCUMENT() if you are using a SAX parser)

Hi

I am not parsing any thing. My source msg conatins foldername and the target should should display file list.

I referred this blog:

/people/rashmi.ramalingam2/blog/2005/06/25/an-illustration-of-java-server-proxy

This is my java file for getting the foldername and

listing the files as response:

==========================

import java.io.File;

public class FolderMI_PortTypeImpl extends com.sap.aii.proxy.xiruntime.core.AbstractProxy

implements FolderMI_PortType {

public jps.FoldernameDT_Type folderMI(jps.FoldernameDT_Type foldernameMT) throws com.sap.aii.proxy.xiruntime.core.SystemFaultException,

com.sap.aii.proxy.xiruntime.core.ApplicationFaultException{

String filesavailable = new String();

String temp = foldernameMT.getName();

File files = new File(temp);

File filelist[] = files.listFiles();

for(int i = 0;i<filelist.length;i++)

{

filesavailable = filesavailable" , " filelist<i>.getName()+"";

}

//Instantiate the response Data type class

FoldernameDT_Type instance= new FoldernameDT_Type(); instance.setName(filesavailable);

return foldernameMT;

}

}

===============

Can you please give me some blogs with simple implementation of Java Server Proxy(end-to-end solution)

Thanks a lot!

Hi

These are for Java Client Proxies. I want for Java Server Proxies.
