Exception when running aync java server proxy scenario.....

[Former Member]

Hi All,

I have created one async Java Server Proxy Scenario in PI7.1 using NWDS7.1. I have successfully completed the below mentioned steps:

1) Created and deployed my java proxy EAR file on non central adapter engine.

2) Successfully registered my server proxy interface using the followng URL:

http://yyyy:51000/ProxyServer/register?ns=xxx&interface=SI_Proxy_IA&bean=localejbs/JavaProxy2&method...

where Jndi- name is: JavaProxy2

But when i am seeing the audit log (under RWB->message monitoing) i am getting some exception and my message status turns into the SystemError . The exception is like this:

Delivering the message to the application using connection JPR failed, dueto:com.sap.engine.interfaces.messaging.api.exception

.MessagingException: Error processing inbound message. Exception: Cannot locate proxy bean localejbs/JavaProxy2.

I have looked almost all the post related to this exception but can't able to figure out the problem.

So, request you all to help me.

Thanks

Amit

Hi Amit,

Try this:

Register in

http://yyyy:51000/ProxyServer/register?ns=xxx&interface=SI_Proxy_IA&bean=JavaProxy3&method=sIProxyIA

don't use local ejbs as it is in decentral adapter engine

Check the document

http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/7d4db211-0d01-0010-1e8e-9b07fc2113ab&override...

http://help.sap.com/saphelp_nwpi711/helpdata/en/a4/d5b3b0b16843b3867c0245d9847ae5/frameset.htm

There it is specified

http://<Host>:<Port>/ProxyServer/register?ns=<Namespace>&interface=<MessageInterface>&bean=<JNDI_Name>&method=<MethodName>

Hi Suraj,

I have already tried this and registered my java server proxy interface after removing prefix(localejbs):

http://yyyy:51000/ProxyServer/register?ns=xxxx&interface=SI_Proxy_IA&bean=JavaProxy3&method=sIProxyI...

But still same exception is coming.

Delivering the message to the application using connection JPR failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error processing inbound message. Exception: Cannot locate proxy bean JavaProxy3.

Thanks

Hi Amit,

>>Created and deployed my java proxy EAR file on non central adapter engine.

In XI adapter the Adapter Engine should point to de-central adapter engine. Try this

Hi Amit,

You are calling a java proxy through PI right? So you might have used XI communication channel for this in the agreement. There in the communication channel, there is a option to specify the Adapter Engine, by default this is always Integration Server, but in your case proxy is on a decentral adapter so you need to change this to the FQDN of the decentral adapter (it should come in the drop down)

Hi Suraj,

As recommended, i was trying to change the Adapter Eninge from Integration Server to the FQDN of the decentral adapter( af.pae.isvsappisb) but it is not coming under that drop down. The strange thing is that for all other adapter types like SOAP,JDBC, FILE etc the Adapter Engine is haing two entries like:

1) Intergration Server'

2) af.pae.isvsappisb

but when i am trying to select XI as my adapter type then Adapter Engine contains only Integration Server.

Please suggest some solution.

Thanks

Hi Suraj,

I think that the XI communication channel which i am using for my java server proxy is fine becoz after selecting XI as my adapter type then Adapter Engine contains Integration Server(by default) there i used to write the port number(in this case it is the port number of non central adapter engine where my proxy beans are deployed) as shown below:

Adapter type: XI

Adapter Engine: Integration Server.

Addressing type: URL address

Target Host: YYYY

Service number: 51000( port number pointing towards the non central adapter engine installed)

And also the message log which is coming under MDT is like this after running the scenario:

2009-10-29 11:55:01 Information The message was successfully received by the messaging system. Protocol: XI URL: http://YYYY:51000/MessagingSystem/receive/JPR/XI Credential (User): XXXX
