Error with receiver java proxy

for a XI type communication channel for receiver Java proxy I see following error in SXMB_MONI.
<i>Unable to read user password from communication channel of type Error when accessing the secure store (access ID = 3650CAFA1FBAA04E8F260C6C4C1923FA) Error while reading from the secure store: ERROR_UNKNOWN: Cannot find entry in secure store (SECSTORE,023).</i>
I have specified the correct credentials for the non sap system in authentication data i.e. XIAPPLUSER and its password.
Any pointers?

Hi Amol
Did you solved this problem? I am also getting the same error when calling receiver java proxy with Adapter type XI.
If you have solved the problem pl let me know.

Java Proxy Runtime: failure to locate proxy bean on inbound call

Hello gurus of the SDN,
I have been trying to get an inbound Java Proxy scenario to work in XI 3.0 but have not been able to get the JPR to recognize my generated and deployed java code. My scenario is set up to call the java proxies generated from a message interface based on the MATMAS Idoc. I successfully deployed the generated java proxies on the same host box as is running the XI instance. The objects are named as follows
Message interface on XI = Inbound_MATMAS04
Generated proxy bean = Inbound_MATMAS04_PortTypeBean
Implementing class = InboundMATMAS04_PortTypeImpl
Implementing method = inboundMATMAS04
I used the JPR transport servlet to register the interface and implementing class but am not sure if I did this correctly. I used the following entry in my web browser:
http://nadcp786:50000/ProxyServer/register?
ns=urn:xiTrainingLabs:groupXX:SAP&
interface=InboundMATMAS04&
bean=InboundMATMAS04_PortTypeImpl&
method=inboundMATMAS04
I also tried using the localejb/ prefix for the bean name in the above step since the code is co-located. When I trigger the scenario, the Idoc info is passed into XI and the Java Proxy Runtime is called, but I get the following error response back in the SOAP header:
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack />
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Finally, appended at the end of this post is the audit log of the messaging system showing that the JPR is called but without being able to locate the bean. I think I am missing a configuration step somewhere, but cant figure out what it is!! Can anyone help me?
Many thanks in advance.

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

Passing File sender adapter paylaod to Java Proxy

I have scenarion that I am getting files from a file adapter and I am not using "File Content Conversion" so file adapter is not converting into any dataType I created for this Scenario to run. The receiver is the Java Proxy as you know the java proxies has input as the MessageType. since we are not mapping incoming file content to any message types then java proxies will not receive the actual Payload.
Question is, How is pass this file content to Java Proxies.
Appreciate your help.
thanks,
laxman

hi,
if you want to put the whole message then you
try this:
- put the whole file into one field (with content conversion)
- then map this one field to one of the fields
fo the java proxy and insinde the java proxy
you will have access to the whole not converted message

Regarding Java proxy in PI 7.1

Hi Folks,
I want to implement the java proxy at sender side in one scenario and receiver side in another scenario.
But when I open the IR> Goto Menu> Java Proxy Generation, it opens one pop up and asking the Archieve (you want to create new one or edit the existing file) file, what is this file and what is this type of file?
Another is, after giving some name then it asks the software component version, when I give this SWCV then it is displaying " ...some ID.. Doesn't contain any active message interfaces"?
What is the reason?
Thanks
Ramesh

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.

Direct Connection ABAP Proxy and Java Proxy possible ????

Hi Folks ,
As i read as direct connection possible between 2 SAP systems only ..
and also i read as WS Direct Connection u2013 (Java) ..
What it means ?? is it ABAP Proxy to Java Proxy using Direct connection ?? Like Java Client Proxy and ABAP Server proxy
I am not clear on this.. Could you please explain or help me on this . ??
Siva..

Hi ,
+You can do both for java proxies as well Abap proxies.+
As per the following points
1. Point-to-point connection is a new capability available with SAP NW PI 7.1. It allows applications or systems to send messages using WS-RM without going through a middleware, e.g. PI, but still using a centralized tool to design and
configure the interfaces and connection properties.
2. SAP XI 3.0/PI 7.00 or higher releases can be licensed based on the total volume of messages in
gigabytes (GB) that is processed per month. The size of the payload is determined in the integration
server. The information is then aggregated according to sender and receiver system.
Question :
1. If Message exchange between 2 SAP applications using direct connection .. Then dont we need to consider about licencing cost for volume of messages per month ?
2. So if i use ABAP Client Proxy to Java Server proxy scenario.. can i use direct connection ? Eg., SAP ECC to java application ?
In both the cases PI Runtime is not required .. Am i right ?
Please clarify..
Siva..

Java Proxy and ABAP Proxy

hi,
can any one send me some documents on Java Proxy and ABBAP Proxy
regards,
John

hi,
Proxies are nothing but a mechanism to shift the application logic from the XI server onto the sender or reciever system so as to reduce the effort on the side of XI.Depending upon where the proxies are generated ,it is differentiated as client proxy ( sender ) and server proxy ( receiver ) .In R3 system having WAS 6.2 and above its already has an inbuilt small IE so the proxy generation is favoured and possilbe,for more on this please go thru the following links
Proxies: are interfaces which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions.
The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
The Proxy currently has the following components available:
1. ABAP Proxy Communication using XI or Web Services
2. Java Proxy Communication using XI (J2EE)

XI 2.0 Java Proxy error

Hi All,
I am receiving the following error:
RFC_ADAPTER.JCO_RUNTIME_EXCEPTION:System error when calling the outbound RFC adapter (cannot deserialize JCo request from XML)
The message I'm sending is synchronous coming from a Java Webapp and requesting infomation from R/3.
There are two pieces to the interface I have created. The first is calling a function which validates a few fields then returns 'return codes'. The second will create a sales order and return a few numbers. They are built into the same interface and use message splitting based on an input field. The verification piece is working which tells me that this is not a problem with the actual RFC adapter but when I run the 'create sales order' function I receive the aforementioned error.
n e thoughts?

Hi Stefan, thx for the reply.
I am running the latest version of the function. I do have one date field in the RFC structure, the rest are strings. The data going into that date field is being mapped from a string field in the sent message. This shouldn't be a problem (I don't believe) I have done this in many other interfaces.
I noticed that in my xi monitor (SXMB_MONI) under the column labeled 'Outbound' the acronym 'RFC' shows up for my failing message. When I send a message through the other java proxy interface that works I get nothing in the column. I'm not sure if this means n e thing but I thought I would through that in.
I've also set up my scenario changing from synchronous to asynchronous and using the file adapter and it seems to make it through, minus the error on the return message.
.. I forgot to mention that there have not been any changes to the RFC adapter configuration. ... and I have restarted it to see if that would make a difference. It did not.
n e other ideas?

Regards,

HI Amol,
Did you check the Message type/Message Inetrface names in the Java Proxy ?
Also check for Receiever Determinations in the configuration.
I assume that , you have created the Communication Channel under the Business System created as Standalone Java System.. If not check this.
Go to SXI_CACHE and check for the Receiever Determination created in the Configuration...
Hope this helps,

Sync Java Proxy Server response in XML

Hi !
We've this scenario: File1 <-> XI <-> Java Proxy <-> File2
Using a BPM, we made a Async/Sync workflow. It works ok. It uses a SYNC Java Proxy Server.
The problem is that inside the java proxy, we query an http source that returns already XML formated data. We need this data to be mapped from the java proxy response message type to the File2 message type.
We know that we can parse the XML data inside the java proxy and fill the response message type structures (creating items, and array items for nested records), or directly code the mapping here.
But, is there any alternative to pass the received XML from the HTTP directly to XI, and map that XML structure with the File2 message type using graphical mapping ? instead of programming the xml parsing and creating the response structure?
If we create a message type for the response of the java proxy, as 1 field that contains the whole XML code, then we would not map it....Is there any way to complete or to add something to the received XML code, to convert it to the XI message format..so XI could interpret it as a true XI message and map it transparently via graphical mapping?
Thanks,
Matias

Hi Akshay !
That's exactly what I don't know how to do it.
Inside the java proxy function I have a string variable, let's call it xmlResponse, that contains:
<customer>
<name>Matias</name>
<country>China</country>
</customer>
I also have a message type created in XI (let's call it MT_Response), that has the same fields as the above message structure. And my java proxy function is declared something like this:
public MT_Response.Type myFunction(MT_Request.Type myRequest) {
String xmlResponse="";
// http connection code goes here..
xmlResponse = httpConnection.getResponse();
return ??????? what ????
I don't want to parse the xmlResponse variable in order to fill the MT_Response structure. I need a more direct way, because the content of xmlResponse is already XML !
Thanks.
