I need very simple and clear steps as to what i should do as far as Java proxy is concerned.Steps to do in NWDS,.
Also am new to Proxies..... What about the Java code.....I don know Java....
Can i find relevant code and screen shots with both client and server Java proxies.
Scenarios with screen shots if possible.
Please post as soon as possible.....

Hi
NWDS
NWDS - NetWeaver Developer Studio - editor, etc used by the developer to code. Developers way to interact with the infrastructure.
NWDS is just a development environment with all robust development tools.
It can run j2ee,j2se and sap applications also.
It is an interface to access NWDI services and applications.
SAP NetWeaver Developer Studio (NWDS) for more details follow : http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/frameset.htm

JAVA PROXIES
You can generate Java proxies for J2EE applications on the SAP Web AS. Proxy generation generates J2EE beans and proxy classes for this purpose. The generated beans satisfy the EJB 2.0 standard.
Java proxy generation is part of the Integration Builder and has the following functions:
·        Create an archive (as a Jar or Zip file) by using one or more message interfaces from the same software component version. The archive contains bean and proxy classes.
·        Open existing archives to regenerate proxies. Proxy generation knows the original message interfaces for which proxy objects are contained in the archive.
Selecting Message Interfaces
You can call Java proxy generation from the design maintenance screen of the Integration Builder in the following ways:
·        From the main menu, choose Tools ® Java Proxy Generation.
·        From the context menu, choose Java Proxy Generation... for message interfaces in the navigation tree.
The latter method has the advantage that the selected message interface and the corresponding software component version can be copied directly. You can only generate proxy classes for message interfaces and not for sub objects of message interfaces.

How to install JAVA API client files :: Using JAVA Proxy & NWDS

Hi
I am going to integrate the SAP with one "AB" System which is providing Java API to integrate with their client ( which in turn will connect with AB System ). So AB System is providing JAR files & property files, in order to instantiate objects & call those APIs.
Now I am going to write the JAVA code in NWDS which is installed on my Laptop so I am sure I need to give this jar files under ::
Project -> Properties and then Java Build Path -> Libraries.
Choose Add External JARs
But where do I need to add property files.
Also do I need to install the same files on XI Server too & do I need to install the "AB" System Client also on XI Server or it can be installed some place else too.
Regards
- Lalit -

Lalit,
>But where do I need to add property files
How are you going to access the properties file? Are you going to use Java IO to read the file or are you dgoing to bundle the property file as a resource and use the getResource() . If you are going to use Java IO then you will have to hard code the property file path in your code and make sure that your Proxy can read the property file.
If your property file is going to vary across environments, I woudl suggest this approach. Make sure that the property file path will be same in all environments and it will work fine and make sure that your proxy will have OS level IO access as well.
Another option would be to have the property file bundled as a respurce, but, making changes to the file in this case will be an issue!
>Also do I need to install the same files on XI Server too & do I need to install the "AB" System Client also on XI Server or it can be installed some place else too.
When you create the EAR file for your Java Proxy, remove all XI .jar files and just make sure that the Client JAR is available in the EAR file. You need not install the Client JAR file anywhere as long as the jar file is a part of the EAR!

Help - how to create java proxy (sender) in NWDS 7.1

Hi,
I am trying to develop a java proxy as sender to send message from WAS to PI.
I am using NWDS 7.1. Let me explain what I have done so far,
1. Received proxy classes from PI
2. Created a EJB Project, imported the proxy classes into EJB project
3. created a EJB bean, local interface in the EJB project and exposed as webservice
4. added the ejb to an ear
5. added reference to the following jar files (external library)
tcaiiproxy_rt_api.jar
com.sap.aii.af.sdk.jar
com.sap.aii.utilxi.server.jar
com.sap.aii.utilxi.core.jar
com.sap.aii.proxy.svc_api.jar
6. able to build and deploy the application
7. able to open the webservice in wsnavigator
Error encountered:
"Server Exception: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sap/aii/proxy/xiruntime/core/AbstractType "
Questions:
1. Which method I should execute / call among all the proxy classes from local bean class to send message to PI?
2. Is it mandatory to add refernces to the application.xml, ejb-jar.xml and other xmls ?
3. How can I test / monitor the message being sent to PI interface?
Thanks and best regards,
Arun prabhu S

plz cross chk the references under application-j2eeengine.xml and ejb-jar.xml
http://wiki.sdn.sap.com/wiki/display/Java/JavaProxyChangesinPI7.1fromPI7.0
u can chk tis article also:

JAVA Proxy :: Exception in ejb-jar.xml in NWDS

Hi All
I am getting exception while Importing (Inbound) JAVA Proxy ZIP file in NWDS, ejb-jar.xml shows the red cross & when I double click on it got following error -->
The content of element type "ejb-jar" is incomplete, it must match "(description?,display-name?,small-icon?,large-icon?,enterprise-beans,relationships?,assembly-descriptor?,ejb-client-jar?)".
I already add the following JAR files in class-path -->
aii_proxy_xirt.jar
aii_msg_runtime.jar
aii_utilxi_misc.jar
guidgenerator.jar
One different thing I also notice is that after adding these JAR files in classpath I am not getting my Inbound Interface BEAN under EJB candidates.
Also nothing is visible under ejbModule usually it shows 4 JAVA files & one template file.
As a solution I tried searching in google & forum for above exception, most threads suggest to add the Beans to xml files but I am not getting my interface Bean under EJB candidates.
I also tried reloading all the external JAR files again from System but still same issue.
Also within the same NWDS one another version of EJB is working fine but I worked on it 6months back, I tried copy its contents to ejb-jar.xml source code but then also nothing happens.
I am using NWDS Version: 7.0.10
Can you pls. suggest & let me know what further information I can provide from my side which can help you to investigate it.
Regards
Lalit

hi,
Your are using server java proxy.
You can use some other jar files apart from what you are using,.
ejb20.jar
exception.jar
sapj2eeclient.jar
and after importing your zip file (create a ejb project first ,then add the zar files and then click on the ejbModule and then import your zip file ) close and open your project.
Do not directly click on ejb-jar.xml.Click on ejbModule and import the .zip file.
then save your .template file in ejbModule as a .java project.
then there should not be any error.
you can refer

Error while running java proxy in PI 7.1

Hi All,
I had created a java proxy using nwds 7.1. This java proxy is called by XI channel and its synchronous.
WHen i run my scenario in PI i am getting a error "Error while sending message: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error processing inbound message. Exception: No remote bean found for reference of class $Proxy2919
Kindly help me finding what can be the issue.
Regards,
Rajesh

Go to the JNDI Browser (Nwa -> Problem Management), and check if the proxy was deployed correctly with the exact name "Proxy2919".
Also, check the OSS note below.

Java proxy client logical port transport to Q and prod issue in target addr

Hi All,
I have a java proxy client having a logical port (configured using NWDS) to consume a web service in the provider system.
In the logical port, I have given target address, and logical port name. While moving this client proxy NWDI dev track to Q and prod,
how do I change this target address to point to Q and prod respectively. In other words, even though I am using Visual admin to configure the destination url for the logical port, to point to Q and prod, its still referring to the dev environment provider service after moving the proxy client to Q and prod. What is the suggested approach to take care of this issue
Thx

Hi Michael,
I can only help from that point of view that I believe this question belongs to the forum

Unable to invoke java proxy in PI 7.1

Hi ,
I am using NWDS 7.2 (Trial ver) and using it to deploy java proxy on PI 7.1.
I also registered the interface using http://<pi>:<port>/ProxyServer url
But when I invoke the proxy I get the error as
"Cannot locate proxy bean"
Please tell me what to do...
regards,
Piyush

Hi,
This sort of error usually comes when JPR cannot find the deployed java server proxy bean.
1) Register ur server proxy using this :
http://host:port/ProxyServer/register?ns=xxx&interface=SI_Proxy_IA&bean=localejbs/Jndi-name&method=method name
refer this: http://help.sap.com/saphelp_nw04/helpdata/en/a4/d5b3b0b16843b3867c0245d9847ae5/content.htm
2)Chk whether u have mentioned the corrcet JNDI name while registering the URL.
3) Chk ur JNDI name under NWA.
4) Chk ur references under application-j2ee-engine.xml.
<?xml version="1.0" encoding="UTF-8"?>

Java Proxy as Sender in PI 7.1

Hello everybody,
I would like to build a Java Proxy as a sender in PI 7.1. To be more precise, I would like to implement an asynchronous distribution scenario from MDM to PI. I understand the process of deploying and calling a receiver Java Proxy, but currently I don't know how to do the sender proxy. I can import the PI WSDLs, but I only get methods with return parameter void, taking the PI message type as input.
public void modifyRecordOutA(mdm.masterdatareplication.ModifyRecordRequest modifyRecordRequest) { }
So far so good, but somehow I have to send the data to PI, right? Could anybody tell me how to do this? Is there any documentation available that does not refer to older versions of the NWDS?
Thanks in advance,
Jörg
P.D.: Hints referring to attach pictures to the request would also be welcome, if there is something special to be considered.

Hi,
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.
But for a Java proxy, I would need a separate Java server(?) to run the application on, is this correct?
You do not need a separate Java server. 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 error: Exception in method methodExists

Hello all!
We are doing the following synchronous scenario: CRM->XI->JavaProxy--->Third party....
Here is the process we are following to deploy our Proxy:
1.Created EJB Module Project in NWDS
2.Import the files generated by XI into ejbModule folder from ZIP file.
3.Renamed *PortTypeImpl.template to *PortTypeImpl.java
4.Compiled all code (no errors)
5.Added all the references to the SAP libraries required (taken from our XI server):
com.sap.aii.proxy.xiruntime
com.sap.xi.util.misc
com.sap.aii.messaging.runtime
com.sap.guid
6.Codified Java Proxy codified the method <interfacename> in the <intefacename>_PortTypeImpl class.
7.Edited ejb_jar.xml to add EJBs.
8.Provided a JNDI name in the file ejb-j2ee-engine.xml.
9.Built EJB archive (no errors).
10.Created a new Enterprise Application Project and pointed build path to our EJB Project.
11.Added our EJB to the Enterprise Application project.
12.Created the references to the SAP libraries in the Enterprise Application Project in the application-j2ee-engine.xml file:
com.sap.aii.proxy.xiruntime
com.sap.xi.util.misc
com.sap.aii.messaging.runtime
com.sap.guid
13.Within the Enterprise Application Project we built an EAR file.
14.We deployed our .ear file to the J2EE Engine via Visual Admin (no errors).
15.We registered our Java Proxy on the ProxyServer, using
/register?ns=<interface_namespace>&interface=<XI_Interface_Name>&bean=<EJB_JNDI_name> &method=<name of the method implemented by you on the _PortTypeImpl>
Actually, we did the following:
url for registering the EJB:
http://ithpsrq0:50200/ProxyServer/register?ns=http://banco.popular.com.pr/xi/crm&interface=mi_AccountInfo_is&bean=popularinc.com/MiAccountInfoIs_Default&method=miAccountInfoIs
Message displayed when listing interfaces (http://ithpsrq0:50200/ProxyServer/listAll)
http://banco.popular.com.pr/xi/crm#mi_AccountInfo_is = popularinc.com/MiAccountInfoIs_Default:miAccountInfoIs
1 interfaces found
When running the interface we get the following error:
com.sap.aii.af.ra.ms.api.DeliveryException: Error checking method name miAccountInfoIs of remote inbound proxy bean $Proxy250: Exception in method methodExists.: com.sap.aii.proxy.xiruntime.core.XmlInboundException: Error checking method name miAccountInfoIs of remote inbound proxy bean $Proxy250: Exception in method methodExists.
Does anyone have any suggestions?
What causes a "methodExists" Exception?
Please help us,
Thanks a lot!!!

Hi,
Is this a runtime of "com.sap.aii.proxy.xiruntime.core"
please check the jars used, adding this jars will solve this i guess.
aii_utilxi_misc.jar
ejb20.jar
exception.jar
jARM.jar
sapj2eeclient.jar
sapxmltoolkit.jar
aii_msg_runtime.jar
aii_proxy_xirt.jar
Also check, application-j2ee-engine.xml and see if,
com.sap.aii.proxy.xiruntime
com.sap.aii.messaging.runtime
com.sap.xi.util.misc
com.sap.guid
You wil get the jars in XI servers, you can ftp and get the jars, but you may need to search them.
Anotherthing, always take the jars from the xi servers to be sure you are compatible with the upgrades .
Hope this solves your problem.
Anirban.

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.

Getting Inbound Java Proxy Exception in method "onMessage"

I have built an Inbound Java proxy, deployed the EJB, viewed it in the J2EE admin tool, registered the JPR settings (also listAll, reviewed results, looks OK), configure the XI scenario. When I run the XI scenario using the Runtime workbench I get the following error in the BPM Synchronous Send step (calling the Java Proxy)
"com.sap.aii.af.ra.ms.api.DeliveryException: Exception in method onMessage".
Does anyone have any suggestions?
What causes an "onMessage" Exception?

Thanks Sudhir Here is the process I am following to deploy my Proxy, would you please validate it. Created EJB Project in NWDS, unziped XI gened proxies into ejbModule folder, renamed *PortTypeImpl.template to *PortTypeImpl.java (will add real code later), compiled all code (no errors), edited ejb_jar.xml to match your suggested format, can view EJB Candidates (and see my Proxy Bean), built EJB.JAR file (via Wizard), created new Enterprise Application Project and pointed build path to my EJB Project, within the Enterprise Application Project I built an EAR file (which includes the "EJB Project JAR File", Deployed Enterprise Application Project to the XI J2EE Engine. I can log into XI J2EE Admin and see my EJB Project and the Proxy Bean I am trying to execute. Is this the process you used to deploy the proxy bean?
Also you you turn on JPR Tracing to see what parameters are passed into the JPR engine?

Hi,
     Thanks for your input..
   I have also opend the EAR as ZIP file and deleted the existing listing libaries
apart from the actual implementing Jar and META-INF folder.
I have tried deploying the Jar for the second time, it is throwing the same error.
What I did is...Once the EAR is created, I went to Resource perspective in NWDS and copied the EAR from the EAR project and used the same for deployment.
Is there is anything else to be modified or deleted before deployement?

XI Configuration incase of Java Proxy

Hello
I am trying Java Proxy scenario in which I generated Java Proxies of my XI interface.I used NetWeaver Developer Studio to implement my business logic using the generated classes from XI.
But I guess its not connecting to XI when tried to execute from NWDS.On XI side I configured Business System with no sender configuration and configured Receiver Determination for the business system (basically similar to what we configure for HTTP Adapter).
Just wanted to get clear whether we need to define Sender(sender comm channel) incase of Proxies or any business system instead of business service.As far as I know since its invoking a EJB directly from the lookup it should not require that but not sure.
Thanks in advance.

Ashish
