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.

Unable to invoke Java WSIF Binding process

Hi,

Please verify that WSDL portType "{http://BusinessProcess/}Greeting" is supported by a service in WSDL file.
Please help.

Hi Jack
Does your WSDL have the "binding" and "service" section? I do not use JDev or anything else to create the WSDL for me, I create it by hand so I don´t know how to help you in JDev, but it seens that JDev does not generate this sections and you must set then in order to use WSIF Bindings to Java or EJB.

Unable to invoke WebLogic 8.1 sp2 web service from a java proxy client...

I am not able to invoke a web service deployed on WebLogic 8.1 SP2 via a client using the proxy jar provided by WebLogic's JWS > Overview > Generate Java Proxy tool.
I am getting a java.net.ConnectException.
Both the client and the WebService are on the same server.
Thanks!!
Inder./

Please see the instructions below. If this does not help, please open a case with customer support and tell them it may be related to CR235479
DESCRIPTION:
When a platform domain is created, the admin server can be started without
any issues and a managed server can also be started without any errors if
using startManagedWebLogic.sh. But when a managed server is started using the
nodemanager, the managed server fails to start with the following error.
The WebLogic Server did not start up properly.
java.lang.NoClassDefFoundError: com/bea/wsrp/util/debug/Debug
(Complete stack trace with be added as a note)
The reason for this is that:
startWebLogic.sh(cmd) and startManagedWebLogic.sh(cmd) for platform domains
call <User domain>/setDomainEnv.sh which includes all the jars necessary for
a platform domain in the CLASSPATH.
Whereas startNodeManager.sh calls <WL_HOME>/common/bin/commEnv.sh, which is
the same for both platform and server installations of weblogic and has only
weblogic.jar in the CLASSPATH.
Looking at historical cases, the steps to start NodeManager successfully in a
platform domain are:
1.
a. Copy admin server classpath (from <user Domain>/startWebLogic.sh) to
that of all managed servers in the 'Remote Start' tab of the WLS Console
OR
b. Copy admin server classpath to <WL_HOME>/server/bin/startNodeManager.sh
(If the same nodemanager is used to manage server domain servers and platform
domain servers, will there be any issue with this approach??)
2. Copy the wsrpKeystore.jks file from your domain directory to the
nodemanager directory (the parent of the directory where all the server
directories are replicated in the node manager. By default: <WL
HOME>/common/nodemanager)
But these steps are not publicly documented in edocs.
CONFIGURATION:
Weblogic Platform Domain 8.1 (all service packs)
WORKAROUND:
Steps 1 and 2 above.

How to invoke a proxy service from a java client

Hi all,
how could I invoke a proxy service from a java client ?
The proxy service type is 'any xml service' with http protocol.
For a proxy with web service type I can export the related WSDL and generate the java client source.
With 'any xml service' there is no associated wsdl and I'm wondering how to do that.
Thanks
ferp

Hi Ferp,
I used ClientGEN to generate client files from WSDL deployed in ALSB. You can also use Axis for client file generation.
You need to know the WSDL URL. Generate Client files from WSDL URL.
Sample ANT Script
<project name="simple-web" default="mytask" basedir=".">
<taskdef name="clientgen" classname="weblogic.wsee.tools.anttasks.ClientGenTask" classpath="C:\bea92\weblogic92\server\lib\weblogic.jar"/>
<target name="mytask" description="Generate web service client">
          <clientgen wsdl="http://<hostname>:<port>/URL?WSDL"
     destDir="src"
     packageName="com.client.mytask"
     classpath="${java.class.path}" />
     </target>
</project>
Use the following JAVA Code,
try {
     ActivationService service = new ActivationService_Impl("http://<hostname>:<port>/url?WSDL");
client = service.getActivationServicePort();
} catch (Exception ex) {
// Handle Exception
client.activateNumber();
Let me know if you need any more information.
Thanks,
Suman.

OWSM 11g: Invoking a secured web service through a java proxy service

Hi All,
I am trying to call a secured bpel service which is expecting a username token password. I have created a java proxy service for the same. I now need to add the username token to the same. Can anyone please guide me in this regard.
Thanks in advance.

Just to add some pointers,
I added the following code to the proxy still the soap headers is not getting propagated.
OrderBookingAndShipment orderBookingAndShipment = orderbookingandshipment_client_ep.getOrderBookingAndShipment_pt();
String username = "OWSM_11g";
String password = "password";
List credProviders = new ArrayList();
//client side UsernameToken credential provider
CredentialProvider cp = new ClientUNTCredentialProvider(username.getBytes(),password.getBytes());
credProviders.add(cp);
Map<String,Object> context = ((BindingProvider) orderBookingAndShipment).getRequestContext();
context.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST,credProviders);

How to invoke ALSB proxy service externaly

Hello,
I.m trying to understand the ALSB and stumble across an issue and hope one of you guys (from BEA) can help out?
I've created the services from the Mortgage services tutorial successfully and now I'm trying to invoke the proxy services externally. By externally I mean as a partner link from within Oracle BPEL. So far this does not work. The error message states a missing protocol in the service URL. I checked this and it is true: the wsdl of the proxy service contains only a relative path (/loan/gateway1), so the protocol and server name and port are missing. Further, I tried to change the URI of the proxy service, but ALSB does only allow a relative URI.
My question is: what am I missing so the proxy service can be invoked externally?
I am on the right solution path to invoke a proxy service instead of a business service, right!?
Thank in advance.
Regards,
Harm Verschuren

I tracked down the problem. The proxy service and the business service it routes to use rpc encoded. The RPC encoded message comes to the proxy service from BPEL which transmits it without modification to the business service. The WLS web service that impements the business service is unable to decode the message persumably because it did not like the way BPEL encoded the message. Below is the message part that BPEL sent: All the xsitype attributes are part of RPC encoding.If you use the alsb test console to pass this message directly to the business service, you will see the decoding error thrown by wls.

Error in generating the Java Proxy

Hi all,
While generating a Java Proxy, I am getting an error :
Unable to generate proxies
Construct not supported
Can anybody please suggest the possible reason and solution for the same.
Thanks and best regards,
Kulwant

In the Integration Repository documentation for External Definitions you find a hint where you can find a document describing restrictions on the handling of XSD.
In that document you can see, that references to global elements are not supported by the java proxy generation.
Therefore, you have to edit your document accordingly.

<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.

I have an inherent dislike of systems and application that have too many moving parts. Keep the moving parts to a minimum.. and the code is faster, more robust, and a lot easier to read, understand and maintain.
So in that regard, I do not understand what the deal is with utl_dbws and why it could not just use plain vanilla PL/SQL..? But then there are likely Java faithful that proclaims The Religion too when designing PL/SQL interface packages in Oracle... :-(
I've posted an example of how to call a web service using PL/SQL code only, no Java, in {message:id=4205205}.

How to generate java proxy in PI 7.1

Hi All,
How do I generate java proxy in PI 7.1
I am unable to see the "Generate Java Proxy" in the Tools menu in the Integration Builder

hi ,
As mentioned in the Question, I am unable to find the "Java Proxy Generattion" link in the Int builder.
Also the help doc says:
Java proxy generation is no longer supported in subsequent releases. For new developments or when making significant changes to a service interface, use Java proxy generation in SAP NetWeaver Studio instead. More information: Creating Outside-In Web Services, SAP NetWeaver Developer Studio.
Does that mean that I can no longer generate java proxy from Int builder?

Piyush
