Inbound Async Java Proxy

I am using an Inbound Async Java Proxy to send via socket three strings, via SXMB_MONI and RWB->MM->MDT I can see message was successfully delivered to JP System that for me is the XI J2EE engine, the JP is not sending anything (the logic is very simple) much worse I hardcoded the strings that is to supose to send and still nothing happens, I think the JPR is not calling the EJB, this is the body of my ejb-jar.xml, I have doubts on the values of the local, home, remote... tags

Synchronous-Asynchronous Interface with Java Proxy

Hi Gurus!!
I have an Interface which begins on SAP with a call to an asynchronous ABAP Proxy . Xi sends the message to Java Proxy Server. This Java Proxy Server calls to a Java Proxy Client that sends the response to SAP through XI. This response is taken on SAP on ABAP Proxy Inbound.
These arquitechture is a requirement, because the time between the request and the response could be 30 minutes and the user shouldn't be waiting the response synchronously.
Is there any way to the user could manage the response in the same "thread" that he opened in the request?
I hope have been clear enough.
Thanks and regards,
Manuel Míguez.

The only possibility I could think of is using correlation. There also you have the limitation of java proxy as it does not support adapter modules. Could you use SOAP for your scenario?
JMS receiver could use inherent properties to define correlations. But as your case is non-JMS, you have to define it manually. Say, if your receiver system is X, then the request from XI to system X should carry its message ID information. While X created the response message, it should use this message ID as the correlation ID for the response message. This could be achieved using an adapter module.
I guess you were not looking for such a complex solution.

Problem with Java Proxy and Socket Connection

Hi Gurus!!
I have developed a Java Proxy that connects via socket with a Server Socket application. This Server Socket application accepts more than one connection at the same time.
When I connect the first time from my Java Proxy, the connection is correctly established. When the first connection opened, if a try a second connection, this is not established.
I use "new Socket(SocketServer,SocketPort);" to open the connection.
I think that all time the Java Proxy is trying to open the same connection, and this is a problem.
Is there a way to indicate to the server that is a new connection and that the existing connections remain?
Anybody could help me, please?
Thanks and regards,
Manuel Míguez.

Hi ,
select XMLTOOLKIT option in Operation mapping and execute it.
I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

RFC lookup with java proxy class, how do I use "fromXml()"?

Hi,
I'm trying to do an RFC lookup in XI using java proxy classes (SAP Enterprise Connector).
The XMLPayload comes from a java proxy class which has been converted to xml using a method called
.fromXml() for this. I just don't know how to use and I can't find any documentation for it.
Would very much appreciate if someone could provide me with an example of how to use this class

Porblem with Java Proxy EJB deploy to XI through NWDI

Situation - I have a web app in Server A (WAS7), it needs to call a java proxy in Server B (XI WAS7). I want to deploy the Java Proxy EJB into the landscape using NWDI. To do this I created an external library with public parts that contains the required jars to build the java proxies. These are aii_msg_runtime.jar, aii_proxy_xirt.jar, and aii_utilxi_misc.jar. The EJB module used part is mapped to the library's public parts. Everything builds fine and the deployment was successful into XI.
Problem - When my web application makes a remote call to the java proxy in XI, NoClassDefFoundError occurs. The first jar that it complain about was aii_util_cimaccess.jar. I included this jar into the library and redeployed. Called the java proxy again, and got another NoClassDefFoundError exception. Now it wanted the lrcclient.jar. I included that into the library and redeployed. Now it wanted another jar. The issue is that all these jars are in the XI server and I shouldn't have to add them as part of the library. Is there a SCA out there that contains these jars, or did I just forget to mark a checkbox somewhere when creating the EJB so that it would reference the XI jars without me adding them to the library?
Note - This architecture works fine without having to add the jars above, if I deploy the Java Proxy EJB from my workspace to XI through the SDM process available through NWDS. This only breaks when I deploy through NWDI.
Thank you in advance.

Send JDBC Data with Java Proxy

Hello,
I Have generated a Java Proxy. And the Data Source is a JDBC Table like:
VALUE01--VALUE02--VALUE03
ROW1-Test1----Test1----Test1
ROW2-Test2----Test2----Test2
Now i can set the Datatypes in XI Proxy with
TYPE.setVALUE01("Test1");
TYPE.setVALUE02("Test1");
TYPE.setVALUE03("Test1");
so i can send a XML like
<TYPE>
<VALUE01>Test</VALUE01>
<VALUE02>Test</VALUE02>
<VALUE03>Test</VALUE03>
</TYPE>
My Problem is to send a XML Data like
<TYPE>
<VALUE01>Test1</VALUE01>
<VALUE02>Test1</VALUE02>
<VALUE03>Test1</VALUE03>
</TYPE>
<TYPE>
<VALUE01>Test2</VALUE01>
<VALUE02>Test2</VALUE02>
<VALUE03>Test2</VALUE03>
</TYPE>
How can is send more than one item throw XI Proxi?
Any Idea or Documentation?

Using a java proxy with XI to execute a Script located in external server

HI
I have recived help from here about this. But i don´t know how to work with java proxy. Is someone there who can help me in it.
Many thanks in advance.
Noelia

Hi Noelia,
You can have 2 types of Java proxies viz. client(putting data into xi pipeline) & server (xi pipeline sends request to these proxies.)
From system point of view, the requirements vary in case of these two. for server proxies you can have a webas java business system and associated technical system in sld.in case of client proxies, refer SAP note #809420.
The basic difference between ABAP proxies and Java proxies is ABAP proxies reside on the perticular application system(CRM or R/3) but java proxies reside on SAP Web AS J2EE stack of your XI server.
Just search SDN pointers on Java proxy developement and you will get good pointers. There is one How-to guide on service marketplace by the name "HowToWorkWithJavaProxies.pdf".
Regarding your dev environment, you can always make use of NWDS, you need to be very much familier with EJB concepts and deployment. Check help.sap.com for more details.

Java Proxy Exception

Hi all,
We are implementing a Inbound syncronous java proxy in our scenario. We were able to create and deploy the EJB successfully in the J2EE engine. The adpater configuration is also working fine. When we fire the message we are getting an exception in RWB saying
<b>Delivery of the message to the application using connection JPR failed, due to: com.sap.aii.af.ra.ms.api.RecoverableException: Exception in method onMessage.: com.sap.engine.services.ejb.exceptions.BaseEJBException: Exception in method onMessage.. Setting message to status failed.</b>
I'm unable to understand the error. Can somebody tell me what this exception means?
Regards
Arvind

Satish,
Thanks for the reply. My biggest confusion here is if the control is actually going to the proxy class.
>>>Delivery of the message to the application using connection JPR failed>>>
When it says delivery of message failed what does it mean , is the message not reaching the proxy class or is it becuase the proxy class is not able to send the message to atrget URL which is the logic which I have implemented in the class.

Arvind

Java proxy in PI7.1.....

Hi All,
I am having a requirement where i have to develop JAVA proxy in PI 7.1 and for this I am using NWDS 7.1 but the main concern is that i am very new to JAVA proxies. Even though i refer SDN but the blogs and forums mentioned are related to XI3.0/PI7.0.
I would be very pleased if anybody clear some of my doubts:
1) Do we require WAS in order to install J2ee based non central adapter engine?If yes how to install it.
2) How to configure client and server proxies in PI 7.1 using NWDS 7.1?
3) How to deploy and test java proxies?
Thanks In Advance.

Hi,
You can install the Java proxy runtime on the SAP J2EE Engine Release 6.40 SP5 or higher.
The messaging system that the Java proxy runtime uses to send messages to the Integration Server must also be installed on the J2EE server.
To send messages from a J2EE application, the application must be programmed against beans that encapsulate all details about the Java runtime. The following classes are generated:
u2022 Proxy classes that send or receive messages using the Java proxy runtime.
u2022 Bean classes as an outer shell that conform to the J2EE standard. The beans call the proxy classes for communication.
The classes must be deployed on the J2EE server together with their J2EE application
see this link for the example scenario https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f272165e-0401-0010-b4a1-e7eb8903501d

Generating Java Proxy

I am having some problems generating a particular java proxy... I've developed several
others without trouble...I suspect the issue is in the imported WSDL.
I have imported an existing WSDL into the "External Definitions" section of
Interface Objects in the Integration Builder ...no problems and the
"Messages" tab properly shows one message. I also checked the rendered
WSDL text on the "WSDL" tab and all looks fine. Note that this WSDL comes from a working web service that is running on a JBoss Applicatino server.
Next I create a Message Interface using this imported WSDL to define my
"Input" message - since this is Async, there is no corresponding "Response"
message - all this goes fine.
Finally, I right mouse click on the Message Interface to generate the Proxy
and at the last step after selecting the MI I get the following message from SAP:
Unable to generate proxies Construct <part type ="....">

According to this document
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/2089f29b-b10a-2a10-5297-e258df0c1bfc
the syntax
<wsdl:part name="GenerateStatements_getStatementInfo" type="GenerateStatements_getStatementInfo" />
is not supported for java proxies.
Unfortunately, u will have to edit the wsdl for working with java proxy.

EJB Module creation in case of Java proxy

Hello
This question might look irrelevant in this forum but its required when we are dealing with Java proxy. I generated Java proxies of my interface which creates around 8 java classes and which supports EJB 2.0 specifications.
In Netweaver Developer Studio (NWDS) I tried to create a EJB Module project and imported these classes into that.Also I manually modified ejb-jar.xml to include the references of Home and Remote Interfaces and bean class.The problem is its not allowing me to create ejb jar of it (the option Built EJB Archive is disabled when right clicked on EJB Module Project).
Waiting for your reply.
Regards
Rajeev

Same thing I solved by closing NWDS, restarting cluster, open NWDS.
You assigned your bean to ejb-jar.xml?
If you have any errors in task list then the option is also disabled.
