Abap proxy and java proxy

Hi
Could you plz tell me when should we select ABAP Proxy and when should java proxy ?? Is it like that in SAP systems we use ABAP proxy and non-sap systems we use JAVA proxy ??
Thanks
Kumar

To connect to SAP system with WAS >= 6.4, ABAP proxy is used.
<i>

Not always. As i mentioned the limitation of ABAP proxy.
Also, Java Proxies cannot be used for any non-SAP application. it is generally used for communication with Java Application

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..

ABAP proxy object and JAVA proxy objects

PCK and Java Proxy Runtime

Hello,
I am a newbie to XI world and have some questions regarding PCK and Java Proxy Runtime. Is it possible to send the message from PCK by using Java Proxy Runtime as Sender?
If yes what exactly configuration steps have to be done on PCK side like SLD & ExchangeProfile configuration according to Configuration Guide or XI Receiver Adapter with Receiver agreement creation?
Thanks in advance,
Viktar

Hi Stefan,
Thanks for information. We successfully checked a simple test scenarion JPR -> PCK -> File. It was necessary to configure properly XI Sender and File Receiver adapters on PCK.
SLD and Exchange Profile were not required to be configurable but in this case we have to use MessageSpecifier interface in client proxy for sender and receiver determinations.

Viktar

Difference between client proxy and server proxy

hi all,
could u explain me the differences between client proxy and server proxy,
regards,
AVR

Hi AV,
simple search in sdn may answer your question,
There are two type of Proxy's in ABAP and JAVA(Clinet and Server),
Clinet ABAP proxy used to send message from ANY SAP System to Integration server,in this case XI adapter not required .
Server ABAP proxy used to send messages from Intergration server to any SAP System,in this case XI Adapter required.
How to implement ABAP proxy comunication refer below link
http://wiki.sdn.sap.com/wiki/display/stage/ABAPproxyproviderimplementationand+testing
The sama way Client JAVA proxy used to send message to Integration sever from any Web Application ,
Server JAVA proxy used to send messages to any destination system ,in both cases XI adapter required.

Regarding Standalone proxy and deploayable proxy

Dear Frds
I want to know abt Standalone proxy and deploayable proxy??
Where are the above used?
In which sceniaria i should use them..
I tried to create a project using Standalone proxy and deploayable proxy but after creating it
i got some doubts how to write client program to acess proxys and where will they be used ??
Thanks in advance
ShravanG

Hi,
Deployable versus Standalone Proxies
SAP Web AS Java provides two types of Web service proxies:
deployable proxy u2013 a Web service client that must be deployed on the J2EE Engine as an application.
standalone proxy u2013 a Web service client that generates stubs and runs without the J2EE Engine. This proxy can be used only with the release for which it has been generated.
Although both proxies have similar functions, there are some fundamental differences.
For the standalone proxy, a stub must be generated and the names and class names of the transport bindings, protocols, and transports that are used must be provided. The drawbacks of this approach are that if a name of a component is changed or requires some modifications, the stub is no longer valid and the whole proxy needs to be regenerated.
On the other hand, with the deployable proxy all information is either generated during deployment or is retrieved at runtime. Therefore, the deployable proxies are to a certain degree protected from runtime changes.
For both types of proxies, ServiceInterface and ServiceImpl classes are generated. Their names are derived from the service name of the WSDL that is used to generate the particular proxy.
For the deployable proxies, only the ServiceInterface is generated at the design time. The client assigns a JNDI name under which the ServiceImpl instace is bound at runtime. The JNDI name is relative to the java:comp/env/ context, which is the default for all J2EE components.
// for Deployed WS Clients
import javax.naming.InitialContext;
InitialContext ctx = new InitialContext();
FooServiceInterface fsi = (FooServiceInterface)ctx.lookup(u201Cjava:comp/env/FooServiceu201D);
At deployment, the service implementation and the service stub are generated. To take the service implementation for the standalone proxy, the generated class must be instantiated:
FooServiceInterface fsi = new FooServiceInterfaceImpl();

We require SSL on all connections. We use a third party certificate with multiple SANs. Since the probe is trying to use https://localhost, it fails because the name doesn't match.
I figure I have a few options: first, is there a way to change the URL that the probe uses to check. This seems to me to be the 'rightest' way I could fix this. Second could I alter the binding of the site so that the localhost hostname uses a dedicated,
self signed, trusted cert? Last, is there any way to simply disable the specific probes? We're a single server low volume setup and I'm not convinced that I need the probes anyway.
IS this a common issue? Outside of the warnings that SCOM throws at me, it is also causing a large volume of logs to be generated.

Hi,
I am afraid it’s hard coded. Just like the “Test-Outlookwebsiervices” command, it will also try the “localhost” and reports errors about certificate host name mismatch issue.
We can safely ignore this report.

Displaying both ABAP webdynpro and Java Webdynpro tasks in the UWL

Hi,
We have two an issue when trying to get the UWL to process two different types of workflow tasks : ABAP webdynpro and Java webdynpro.
Examples of these tasks are:
TS12300097 u2013 LeaveRequestApprover u2013 Java Webdynpro
TS17900100 - ASR_PROCESS_EXECUTE u2013 ABAP webdynpro
We have two backend systems configured
SAP_ECC_Financials u2013 This has the WAS host pointing to the java stack (xxx:50000)
SAP_ECC_Workflow u2013 This has the WAS host pointing to the ABAP stack (xxx.80xx)
In transaction SWFVISU all the tasks which use Java webdynpro have been configured to use the u2018Javau2019system (SAP_ECC_Financials) using the SYSTEM_ALIAS parameter
In the UWL configuration the system SAP_ECC_Workflow has been registered
In addition to this all u2018Javau2019 tasks have had an extra UWl config XML created to ensure that the SYSTEM_ALIAS is set to SAP_ECC_Financials
The system SAP_ECC_Workflow has been re-registered
The UWL cache has been cleared
However when we try to launch the java webdynpro tasks the system is trying to access the ABAP stack (It is still trying to access the Web AS location for the system SAP_ECC_Workflow even though the system alias was specified as SAP_ECC_Financials )
The ABAP webdynpro tasks (in this case a HCM process and form) are launched correctly
If we try the reverse (i.e register the Java system SAP_ECC_Financials and change the SYSTEM_ALIAS parameter for the ABAP webdynpro tasks to system SAP_ECC_Workflow) then the reverse happens. The java tasks can be launched and the ABAP tasks cannot.
Does anyone have a solution to this problem. Surely other people have implemented both ABAP and Java webdynpro workflows?
Any help much appreciated
Andrew

Thanks a lot for all your replies..
The workitem type registration has been done already, but still it doesn't work..
But here is the actual problem...
There is a link 'Execute Workitem' in the inbox of the approver, or the second level manager...
In the leave application, when we click on this link it is taking to the portal as the task is the Webdynpro Java application task. Whereas, when using ABAP webdynpro application task, it is taking to R/3 - which means that the user cannot access this link without R/3 access. The users are given only portal access, they don't have access to backend R/3.
The requirement is that the link has to take the user to portal directly instead of R/3 - i.e it should ask only for the portal id and password.
Since it was working fine with leave application, I changed the task to Java webdynpro task, but I think the Java Webdynpro application is not deployed in the server.
Please can anybody suggest.
Best Regards,
Sushmitha

Trasnparent proxy and reverse proxy at the same time

Can I have in a Content Engine v 4.2 transparent proxy and reverse proxy at the same time ?

Yes, as long as you are not redirecting the two services on the same interface. One service takes precedence over the other and I believe transparent web-cache redirect takes precedence over reverse-proxy.

Communication between SOAP and java proxy does not work

Hi Group,
i want to proceed following scenario:
SOAP->XI->JavaProxy
For that i have created of the message interface of a remote function module my java proxy.
Calling the java proxy with following scenario works successfully:
RFC->XI->JavaProxy
Further, i have created in the integration engine(configuration) my wsdl file. In the SAP
Netwaever Developer Studio, i have made a standalone proxy project, that is consuming the
web service out of the wsdl file.
Testing the web service client with following example works fine:
SOAP->XI->RFC
But when i try the scenario SOAP->XI->JavaProxy, i get following rmi exception on client side:
java.rmi.RemoteException: Service call exception; nested exception is:
java.lang.Exception: Element 'Z_GPS_PING.Response' not found in response message.

In the monitoring, the execution of both directions is ok. In the response message, i can see the result of the java proxy.
Here is the result:
<ns:Z_GPS_PING.Response xmlns:ns="urn:sap-com:document:sap:rfc:functions">
<E_RETURNCODE>PINGOK </E_RETURNCODE>
</ns:Z_GPS_PING.Response>
My first thought, was, that i have a problem with the prefix, so i have changed it via xslt transformation into "rfc",
but it got the same error message.
Does anyone know, which problem we have here?
For any hint or suggestion, i would be much obliged.
Greetings,
Sigi
P.S. WAS and Sap Netweave Dev Studio is on patch level 12

Hi Group,
the SAP has solved the Problem now.
The coresponding OSS note is: 862926
(release date 18.07.05)
The reason was, that the response payload name wasn't
"maindocument". For that, the adapter didn't found the payload and returned an emty one.

Doubts about HTTPS requests and Java proxy

Hello,
I need help about SSL connections and Java.
I'm developing a HTTP/S proxy with Java. To test my proxy, I use Firefox. I configure the proxy option in the browser. The proxy works good with HTTP requests, but with HTTPS requests doesn't work and I don't know why.
I explain the steps that I do for a HTTPS request:
* The browser sends a CONNECT message to the proxy.
I check that the proxy receives the CONNECT request correctly.
* The proxy establish a secure connection with the content server.
I use an SSLSocket to connect with my content server, and the SSL handshake is succesful.
* The proxy sends a 200 HTTP response to the client:
I send
HTTP/1.0 200 Connection established[CRLF]
[CRLF]
to the application client (Firefox)
* The proxy sends/receive data to/from Firefox/content server
I have a Socket between Firefox and my proxy, and a SSLSocket between my proxy and my content server. I use two threads to communicate the client and the server.
Java code:
//Thead server-->proxy-->application(Firefox)
ThreadComm tpa = new ThreadComm(bis_serverSSL, bos_app);
//Thread application(Firefox)-->proxy-->server
ThreadComm tap = new ThreadComm(bis_app, bos_serverSSL);
The "tpa" thread reads from the SSLSocket between the proxy and the server and sends data to the Socket between the proxy and Firefox.
The "tap" thread reads from the Socket between the proxy and Firefox and sends data to the SSLSocket between the proxy and the server.
This is the class ThreadComm:
public class ThreadComm extends Thread{
    private BufferedInputStream bis = null;
    private BufferedOutputStream bos = null;
    public ThreadComm(BufferedInputStream bis, BufferedOutputStream bos) {
        this.bis = bis;
        this.bos = bos;
    @Override
    public void run() {
        int b = -1;
        FileOutputStream fos = null;
          do {
               try {
                    b = bis.read();
                    System.out.print((char) b);
                    fos.write(b);
                    bos.write(b);
                    bos.flush();
               } catch (Exception ex) {
                    Logger.getLogger(ThreadAplicacionProxy.class.getName()).log(Level.SEVERE, null, ex);
                    //b=-1;
          } while (b != -1);
    }But this doesn't work and I don't know why.
I have an Apache server with the mod_ssl enabled as content server, I can send requests (with Firefox) to the port 80(HTTP request) and 443(HTTPS request) without use my proxy and it works. If I use my proxy, HTTP request works but with HTTPS request doesn't work, I look the log of Apache and I see:
[Tue Apr 27 17:32:03 2010] [info] Initial (No.1) HTTPS request received for child 62 (server localhost:443)

[Tue Apr 27 17:32:03 2010] [info] [client 127.0.0.1] Connection closed to child 62 with standard shutdown (server localhost:443)
Why it say? Invalid method in request \x80\x7f\x01\x03\x01 , my proxy sends the data that the Firefox sends.
I think than I have follow the explanations of [1] but doesn't work, I have problems in implementation in Java but I don't know where.
I appreciate any suggestions.
Thanks for your time.
[1] http://www.web-cache.com/Writings/Internet-Drafts/draft-luotonen-web-proxy-tunneling-01.txt

ejp, I have checked the socket between the proxy and server and ... You are right! , I was using the port 80 instead of the 443 (incredible mistake!, I'm sorry). I was convinced that I was using the port 443... Well, is a little step, but I still have not won the war :)
If I see the log files of Apache, We can see that something goes wrong.

I think that this happens because Apache receives the data without decrypt, this is the reason because in the log we can see the "Invalid method in request \x80\x7f\x01\x03\x01". This supposition is true?
ejp, you say that the "Termination is quite tricky." I have changed my code following yours suggestions (using the join and the shutdownOutput) but the threads don't die.
I explain you what I do:
(in time 1)
I launch the thread (threadFirefoxToApache) that reads data from Firefox and sends to Apache.
I launch the thread (threadApacheToFirefox) that reads data from Apache and sends to Firefox.
(in time 2)
threadFirefoxToApache sends the firts data to the server.
threadApacheToFirefox is waiting that the server says something.
(in time 3)
threadFirefoxToApache is waiting that Firefox says something.
threadApacheToFirefox sends data to Firefox.
(in time 4)
threadFirefoxToApache is waiting that Firefox says something.
threadApacheToFirefox is waiting that Firefox says something.
and they are waiting... and never finish.
In time 2, these first data are encrypted. The server receives these data and It doesn't understand. In time 3, the server sends a HTTP response "501 Method Not Implemented", here there is a problem because this data must be encrypt. According to the documentation that I read, the proxy cannot "understand" this data but I can "understand" this data. What's happen?
Firefox encrypt the data and send to the proxy. This It's correct.
The proxy encrypt the data another time, because I use the SSLSocket to send the data to the server. Then the server receives the data encrypted two times, when decrypt the data gets the data encrypted one time. And this is the reason why the server doesn't understand the data that sends Firefox. It's correct? May be.
Then If I want that the server receives the data encrypted one time I need to use the socketToServer, It's correct?
I will supposed that yes. If I use the socketToServer, the proxy doesn't understand nothing, because the data received from the socketToServer are encrypted (I only see simbols), but the Apache log says that there is a problem with the version? (If I use the socketToServer the threads die)

What option is the correct? I need use the SSLSocketToServer or socketToServer to send/read the data to/from the server?. Use the SSLSocket has sense because the data travel in a secure socket, but use the Socket also has sense because the data are encrypted and they are protected by this encription. It's complicated...

Also can anyone please provide links relating to the PI architecture diagram describing it from ABAP and Java Stack Perspective and not from the Components perspective i.e. Integration Repository and Directory.
Thanks.

Hi
Tha ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.
The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.
Most of XI pipelines happens in the ABAP stack.
All messsages picked by the Adapter Framework running on the J2EE engine are passed to the Integration Engine, which does the routing. The mapping program again gets executed on the Java stack and the rest of the pipeline servies are executed again on the ABAP stack and so on.
Message, Java & XSLT (under Imported Archives) mappings are executed at Java stack;
ABAP & XSLT (in ABAP stack) mappings are executed at ABAP stack.
