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.

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.

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

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.

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?

Entity EJB deployment on Oracle through JDeveloper 3.2

I have a project which is using Oracle 9iAS as the for the web server. There were intial plans to use the 8i database within the 9iAS machine as the place where the EJBs would be stored. There was a comment from the Oracle support people that the EJBs would be better off stored on the backend. We are trying to do the same.
We have experienced mainly two problems
1) While trying to deploy the container managed beans through JDeveloper, just after creating the deployment profile, an error ORA - 00904 comes up. (no columns). Then there is a prompt to install BC4J. On doing that the error comes up again and while it goes further, it says 'Exhausted ResultSet'. But the BMP entity beans are working OK.
2) We had a bug report from the Oracle people on entity bean support through JDeveloper on non-NT machines. But we have been trying to deploy beans on the Solaris DB using JDeveloper and we keep getting 'peer socket disconnected errors'. I'll try the workaround which was suggestesd by the Oracle people to solve the problem and get back on this.
I don't know how Oracle will measure up to the performance when EJBs are running. But the problems mentioned above would have to be solved first.
Can anyone help out?
Thanks in advance.
Aby Philip

I can't resist a comment here. Oracle folks seem to always recommend putting the EJBs in back-end database. How many real-world enterprise-scale applications (i.e., one's that would need EJBs at all) have a non-shared back-end database? And in those cases, who in their right mind would accept running application code in the back-end database? I guess Oracle just hasn't really bought in to the concept of multi-tiered applications. The whole reason for separating the business logic tier from the EIS tier is to insulate the EIS services from the demands of the business logic code.
So from that perspective, I would highly recommend running an 8.1.7 instance in your middle tier to house your EJBs. Then you can hook up to your EIS tier either with database links, or (for better performance) by caching data in the EJB database from the EIS tier.
As for your specific issues, I can't help with the first. On issue 2, I am installing the 8.1.7.1 patch set today and I'll let you know if it fixes the JDeveloper --> Solaris deployment problem.

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.

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.

Java Proxy Client !!

Hi Guys,
I need clarification in regards with " JAVA CLIENT PROXY"
Questions
1) Well for sender (client proxy -- JAVA) what is the CC configuration ? Do we need Sender Agreement?
2) After i have used the ZIP file in the NWDS and deployed in the JAVA J2EE Server of XI , how to call this ??
3) What kind of code should i use to invoke the proxy ? kindly elobrate this with some links as am new to JAVA development?
4) Any walkthrough of the entire process would be helpful>
kind:ly share u r thoughts on "JAVA CLIENT PROXY"
Than

Venkat
Pls. go through the PDF " How to Work with JAVA Proxy " which will give lot of insight what all requirements & configuration you need to develop Proxy scenario.
Also go through the document named " Creating First J2EE Application using Dev Studio ".
All of your questions will be answered by these 2 docs.

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

the syntax

is not supported for java proxies.
Unfortunately, u will have to edit the wsdl for working with java proxy.

So how else ,I went through some earlier Posts but it dint help
Please advice as to how one can implement MS ACPI using java or is
it a Wild Goose Chase .I am totally clueless
Also,
can i have some name of Crypto providers (for Java)
i have already implemented bouncy castle
Thanks

The algorithms are the same whether you use MS or BouncyCastle, etc.

What I did to solve this problem was to
create a simple RMI remote object that
resides outside the database JVM and that
serves as a proxy EJB client for your java
stored procedure. The stored procedure can
invoke a method on the remote RMI object
which then looks up the EJBean's home
interface and invokes the relevant method on
the bean's remote interface, and relays any
return values back to the java stored
procedure.
Hope this helps,
Avi.
