Consume Portal Service from J2EE web application

hi, i am a newbie to portal content development. My team have developed a J2EE web application to be run on the portal. Is it possible to consume a Portal Service from J2EE web application? If possible, deeply appreciate if you could provide some guidelines. Kindly advise. Thanks.

Hi Theodore Yu,
You need to expose your portal service as a webservice to consume it in a j2ee web application.
For exposing a portal service to webservice check this link

Accessing custom Portal service from a java application

We have a custom portal service that connects to BW using xmla. How do you access this portal service from a java application. Not from web dynpro, jsp or servlet but from the java code.
Can we use the INITIAL_CONTEXT_FACTORY to get access to the portal service.
Thank You
D.K

Now I tried the following:
I've added the prtapi.jar and the service's jar to the additional-lib folder and added the appropriate entries to library.txt and reference.txt.
Now I can obtain now the PortalRuntime, but this is not initialized.
Has anybody a solution for this problem? Help would be high appreciated!
Regards,
Matthias

Calling a java application from j2ee web application

Hi,
I have a j2ee application in which i am making a call to a jar file which is a java application.
Runtime a4 = Runtime.getRuntime();
Runtime a = Runtime.getRuntime();
String cmd[] = new String[14];
cmd[0] = "cmd";
cmd[1] = "/c";
cmd[2] = "start";
cmd[3] = "javaw";
cmd[4] = "-jar";
cmd[5] = CATALINA_HOME+"\\webapps\\AveksaTesting\\AveksaTestingJava\\dist\\AveksaTestingJava.jar";
cmd[6] = SERVER_TESTS;
cmd[7] = COLLECTOR_TESTS;
cmd[8] = SYSTEM_TESTS;
cmd[9] = CREATE_ORACLE;
cmd[10] = DB_NAME;
cmd[11] = DB_DUMP;
cmd[12] = email;
cmd[13] = isMIGRATE;
try{
java.lang.Process p = a.exec(cmd);
Now in the called java application, i am first shutting down the tomcat server by calling shutdown.bat script and then starting it using startup.bat. But the problem i am facing is when i restart the server from java application, it says address already in use(i.e. port 8445 on which tomcat is runninng).
Id i just call the java application and do the same operation it works fine. I guess when i am calling java from j2ee application, j2ee still has some threads holding java and not shutting down tomcat properly.
Can anyone suggest me what can be done in this case. I have to call a java application from j2ee and restart the tomcat server many times.
Thanks in advance

Cannot access Portal Service from Web dynpro DC

Hi all,
I cannot access the portal service from my web dynpro dc.
1. I created a Portal Service (say xxxservice) in a DC (say the DC name is testservice and the vendor is xx.com)
2. Created a public part under the testservice DC and added my classes to it.
3. Built and deployed the testservice DC.
Now,
4. I created a web dynpro DC.
5. In the used DC section added the public part of the testservice DC and also the epbc.prtapi._api.jar for build time and runtime with strong qualifier.
6. In the web dynpro "Sharing Reference", I added PORTAL:xx.com/testservice
7. In the component controller, I am calling a method from the Portal Service.
8. Built the web dynpro DC and deployed it.
9. But at the run time it gives, NoClassDefFoundError on the xxxservice.
I looked at many forum threads and tried everything. For eg: changed the Sharing Reference to PORTAL:sap.com/testservice but nothing works.
Please do suggest me if I am missing something
Thanks

Hi Laxmi,
I am sure something wrong at Portal Service DC creation. On webdynpro part you done fine .. by putting PORTAL:sap.com/testservice
Check the below steps:
1. Create DC Portal Applicaiton Stand alone (SDA)
2. Add portal Service for the newly created portal service dc
3. build and activate
4. by default you should be get public part by name API which is compilation dependency
5. here you dont need to do anything else
6. on webdynpro just add the used dc to this API public part of portal service dc
7. add PORTAL:sap.com/testservice sharing reference
If u go by this you shouldnt get any error..
Now, u are saying something like ur own classes .. i think u are trying to put u r own classes to service.. but remeber portal service is to have only IYourService class and YourService class.. other classes should be made to be jar.. and add that jar to External library DC and create PPs compile & Assemble and add that DC to current service dc.
Hope it is clear.. if not pls let me know..
Thanks,
Raags

Retrieve Portal Service from EJB

Hi All,
I am trying to use a custom Portal Service from an EJB application. I assume that I have to do the JNDI lookup for the service since I can not use the usual "PortalRuntime" to get the service instance.
Looking at the JNDI browser in the Visual Admin, I can't seem to find it. I have seen some code snippets on SDN for UWLService where lookup is done via "/broker/services/XXXX.KEY"
Any insight?
Thanks,

Unable to consume secured Web service from a Dynpro application

Hello,
I have followed <a href="http://help.sap.com/saphelp_nw04/helpdata/en/c3/bac36a469e4c75aba646077e71516d/frameset.htm">this tutorial</a>
in order to protect and consume a secured Web service from a Dynpro application using SAP logon ticket.
The problem is that after implementing everything needed I receive 401 Unauthorized when I am trying to consume it from the web dynpro side.
If I manually transfer the request the credentials, before the execute i.e:
modObj._setUser
modObj._setPassword
modObj.execute();
I am able to call it, meaning the dynpro application doesn't transfer these credentials to the Webservice even though it's authentication property is set to true.
Any idea how to solve it?

Setting WebDynpro project property
o Project>Properties>Web Dynpro References-->Interface references

SSO from portal to Java based web application not happening

Hi,
We are trying to configure SSO from SAP Enterprise portal with Java based
web application(Solaris on SPARC 64 bit).
Then we downloaded library files for "Solaris on SPARC 64 bit" from
service market place from the path "Support Packages and Patches"
Additional Components" SAPSSOEXT".
We are successful in sending the portal side cookie to the application.
But while loading the library files we get the following error
INFO | jvm 1 | 2009/04/13 04:47:00 | java.lang.UnsatisfiedLinkError:
/usr/local/blackboard/apps/tomcat/lib/libsapssoext.so: ld.so.1: java:
fatal: /usr/local/blackboard/apps/tomcat/lib/libsapssoext.so: wrong ELF
class: ELFCLASS64 (Possible cause: endianness mismatch)
Can you please suggest us what went wrong in this whole process.
But when i tried with the 32 bit library files i was able to load libsapssoext.so file but when I
tried to initialize libsapsecu.so i got the below message
java.lang.Exception: MySapInitialize failed: rc= 14
Also do we require to take"SAPSECULIB" from Support Packages and Patches" ...>Additional Components" ...>SAPSECULIB" ...>SAPSECULIB 5.4 for this SSO activity.
Please get back on this ASAP as we are nearing the golive date.

Calling portal service from web service

Hello,
I'm trying to call portal service from web service. Is this possible? I'm getting an error.
For example, code:
IJCOClientService clientService = (IJCOClientService) PortalRuntime.getRuntimeResources().getService(IJCOClientService.KEY);
.. is generating exception:
java.lang.LinkageError: Class com/sapportals/portal/prt/runtime/IPortalRuntimeResources violates loader constraints
Do anybody knows what's wrong?
Best regards,
Josef Motl

Hi Josef,
Is the IJCOClientService located on the producer side or on the consumer side?

Calling a Portal Service from within a Web Dynpro DC

Hello,
I am trying to call a Portal Service from within a Web Dynpro development component without sucess.
Can anyone give me some hints on the necessary steps in order to accomplish this task?
Thanks
Diz

Hi Diz,
I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
1. Created a DC "Portal Application Standalone" project by the name myservice.
2. Created a portal service inside myservice by the ame AmitsService.
3. Exposed IAmitsService.class in the public part.
4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
Now..
5. Created anoter DC of type WebDynPro
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
8. Tried to reference the service using the following code..
IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
9.Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService

Illegal type in constant pool
I only started to solve the first one. I assumed that I have to add the right .jar to manifest file (please let me know if I am wrong). I tried to do by adding the textual classpath rt.jar, however I am not able to give it the right path:
C:\Archivos de programa\IBM\SDP\runtimes\base_v7_stub\java\jre\lib\rt.jar (even though I split the too long sentence into two and I include an space at the beginning of the second, I still get an error when saving)
I would appreciate any help
A) to solve the existing problems
or
B) To create a web service client in an EclipseME application through any other method.
Thank-you very much in advance,
Guadalupe
PS Any clue is welcomed!!

Hello rss,
If you want to invoke a web service from a JCD you will have to build the SOAP message using JAX-RPC or AXIS and then programmatically creat an HTTP connection.
Or you can leverage the HTTP(S) eWay and then you only have to build the SOAP message.
Or use eInsight. You can import a WSDL into eInsight and eInsight will offer you a business process Activity to invoke the web service operations defined in the WSDL.

SocketTimeoutException when calling a web service from a WD application

I'm trying to call a method of a web service from my WD application. The execution of the method longs more than 60 sec, so I'm always getting:
Service call exception; nested exception is: java.net.SocketTimeoutException: Read timed out
I've got this post, which tells to change the property "socketTimeout" of the client.
Read Timed Out Error
But I don't know what is the client in my WD application, does this refer to the logical port ?
I've tried inserting this into wdInit:
com.hesa.hesanet3.h3wsmodel.proxies.Hesanet3Impl service = com.hesa.hesanet3.h3wsmodel.H3WSModel.getServiceImpl();
logicalPort =(com.hesa.hesanet3.h3wsmodel.proxies.Hesanet3ViDocument) service.getLogicalPort("Config1Port_Document", com.hesa.hesanet3.h3wsmodel.proxies.Hesanet3ViDocument.class);
logicalPort._setProperty("socketTimeout", "30000");
But it doesn't work.
I've tried getting the logical port from the model object corresponding to the method of the webservice unsuccesfully.
I've tried with Visual Administrator -> instance -> Web Service Container -> Settings -> WS Clients Socket Timeout, increasing to 120 secs. No result, still stop at 60s.
I've tried with Visual Admin -> global configuration -> Http provider -> KeepAliveTimeout, increasing to 120 secs, and still stop at 60s.
I can't change model object code, but I've tried to debug it and setting the property in stubForLogicalPort and in _getGlobalFeatureConfig(), without change.
I'm using a HTTP Destination, does this have something to do?
I'm getting insane with this and I'm in urgent need of help.
How can I change the time the WD waits for the WebService to answer ?
Thanks in advance.

Find solution. Check this thread:
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/faq%2b-%2bmodels%2b-%2badaptive%2bweb%2bservice
The com.sap.tc.webdynpro.model.webservice.api.IWDWSInvocationModifier interface can be implemented by an application using the Adaptive Web Service model in order to modify the web service invocation object just before it's execution. Invocation modifiers need to be registered with the executable model class for which invocation is to be modified:
Request_NumberToWords requestMO = new Request_NumberToWords(model);
requestMO.wdSetInvocationModifier(
new IWDWSInvocationModifier() {
    public void doModifyInvocation(Object port) {
      HTTPControlInterface httpItf = HTTPControlFactory.getInterface(port);
      //timeout for this WS invocation is 120 sec; don't use global config. setting of WS-Runtime
      httpItf.setSocketTimeout(120000);
    public void doModifyAfterInvocation() {}
Best regards.

Help me! How to use it as a web service from third party application?

After using JDeveloper to develop BSSV object e.g. JP550010, how to use it as a web service from third party application?
TKS！

Obviously the OP is working on a project for the Bead Society of Southeastern Virginia http://www.bssv.org. Oh, wait, maybe he's researching the Blueberry Shoestring Plant Virus http://abbreviations.yourdictionary.com/bssv
