How to call EJB deployed on websphere from JSP running on Tomcat?

I am trying to establish communication between two app servers. I have a sample EJB deployed on Websphere and wish to call its business methods from a JSP page which is running on Apache Tomcat server. (ie) Tomcat is client to websphere. Is it possible to do? If so, what are the client Jar files of websphere that I should make available to JSP page on Tomcat? Do I need to set any Jars in Tomcat environment variables? Lood forward for your immediate help. Thanks in advance

Please see the thread

How to call EJB deployed on OC4J from java stored procedure?

Hello,
I'd like to call EJB from java stored procedure. My example works fine from command line, but the problem seems to be with deployment of this code into database. Especialy I'm wondering how to reference jars like oc4jclient.jar, ejb.jar, ... from java stored procedure.
Is there some example how to do that ?
Can You help me please ?
Many thanks,

How to lookup EJBs deployed in OC4J from a standalone client application

Hello all,
I am trying to lookup an EJB deployed in OC4J 10.1.3 from a standalone client application using the following code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://localhost:23791");
env.put(Context.SECURITY_PRINCIPAL, "jazn.com/test");
env.put(Context.SECURITY_CREDENTIALS, "test");
Context context = new InitialContext(env);
Object ref = context.lookup("ejb/Dispatch");
I get the following error:
javax.naming.NameNotFoundException: ejb/Dispatch not found
     at com.evermind.server.rmi.RMIClientContext.lookup(RMIClientContext.java:51)
     at javax.naming.InitialContext.lookup(InitialContext.java:347)
For the lookup string I've also tried:
"java:comp/env/ejb/Dispatch" and "Dispatch"
For the Context.PROVIDER_URL property I've also tried:
opmn:ormi://localhost:6003:instance
The result is always the same.
I appreciate if someone could help me with this?
Thanks,
Georgi

Georgi,
Your question has been discussed many times on this forum. Search the forum archives for "RMIInitialContextFactory".
The PROVIDER_URL needs to include the name of the deployed application that your EJB is part of, for example:
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/MyApp");The lookup name has to be the value of the "ejb-name" element in your "ejb-jar.xml" descriptor file.
Your SECURITY_PRINCIPAL value looks strange to me. Personally, I use "principals" (and not JAZN), so I modified the "application.xml" file (in the "j2ee/home/config" subdirectory) to use "principals". Look for the following comment in that file:
Good Luck,
Avi.

What I did to solve this problem was to
create a simple RMI remote object that
resides outside the database JVM and that
serves as a proxy EJB client for your java
stored procedure. The stored procedure can
invoke a method on the remote RMI object
which then looks up the EJBean's home
interface and invokes the relevant method on
the bean's remote interface, and relays any
return values back to the java stored
procedure.
Hope this helps,
Avi.

How to call a Bapi or RFC from a custom logon module

Can you provide an example of how to call a bapi or rfc from a custom logon module? (used to authenticate in portal)

Hello all,
Is it possible to use SAP JRA instead?
We have a Connector deployed on the WebAS 6.40. From an EJB (Webservice) it is possible to lookup the connector, but if i try to lookup the connector from a custom LoginModule, i get the following error:
Path to object does not exist at java:comp, the whole lookup name is java:comp/env/eis/SAPJRA_CRMDC.#
The whole lookup in LoginModule looks

Issues in looking up a ejb deployed on glassfish from tomcat.

Hi all,
I have followed the steps mentioned in the EJB FAQ in the glassfish site and was able to lookup a remote ejb deployed in glassfish from a standalone client.
In case of standalone client, i set the appropriate jndi properties in the initial context as mentioned in the FAQ and added the 4 jars specified to the classpath of the application.
It all worked perfectly well.
But I attempted to do the same from a servlet running under tomcat.
I set the appropriate jndi properties in the intial context and added 4 jars specified in the lib directory of the war file.
But this did not turn out well and tomcat complained me with some servlet init errors.
Then i searched through the web and found this posting from you:
http://www.archivesat.com/GlassFish_Enterprise_JavaBeans_Developers/thread1399339.htm
Then i created a folder called "shared/lib" under TOMCAT_HOME directory in my machine and ran the same example. Wow.....miraculously the application ran well.
But i found that the "index.jsp" which i configured in the welcome file list does not appear now. But i was able to access the servlet without any problem. And the servlet was able to successfully lookup the ejb deployed in glassfish.
Then i thought, let me try to access the ejb from a jsf application.
Then i created a jsf application in netbeans 5.5.1 and tried to access the bean deployed in glassfish.
(Note: the jsf application runs in tomcat 5.5.17 which is bundled with netbeans)
OOPSS....
Tomcat now complains me that it cannot compile the jsp page..
This is the error i got...
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
C:\Documents and Settings\james\.netbeans\5.5.1\apache-tomcat-5.5.17_base\work\Catalina\localhost\CityExplorer-WebClient1\org\apache\jsp\index_jsp.java:7: org.apache.jsp.index_jsp is not abstract and does not override abstract method getDependants() in org.apache.jasper.runtime.JspSourceDependent

Any ideas...
Can you please help me.
I've noticed that you were eagerly answering questions related to ejb lookup in many places.
I feel there is some potential compatability issue between tomcat and glassfish...
I request you to investigate on this and clarify the community with your response.
Thanks in advance,
James Selvakumar

Thank you guys!
I've found the answer myself.

How to call a custom controller method from view

Hi,
I ve created a simple web service and consumed it in a model. Mapped the input & output parameters to custom controller context which in turn mapped to component controller's context which in turn to view's contexts.
How to call a custom controller method from view?
Please explain the syntax.
Regards,
Manoj.

Hi Patralekha,
Give some idea for the below scenario:
I ve created a simple web service and consumed it in a model. What I did was
1) for the input parameters, mapped the node from view->custom controller->model
2)for the output parameter, mapping from model->custom controller->view.
It works fine.
But I don't want to access model nodes directly, rather I want to set the input param in somewhere else (like custom controller) before calling the appropriate method, same for the response also.
Share me your thoughts.
Regards,
Manoj.

How to call an external web service from OIM?

Hi,
I have a question on how to call an external web service from OIM within e.g. creating user process? How should it be done; through adapter and task in the process?
Any recomendations?
Thanks in advance!

it is not clear to me if you are having problems with calling java code from OIM or if the problem is the web service API.
Lets do some divide and conquer:
Can you create a simple java class that just writes a couple of lines to the log? Please attach this code to the OIM task and make sure it runs.
Once this works we can start looking at the web service call.
Best regards

RE: How do I access deployed TOOL libraries from mycode?

Hi Martin,
sorry for the late answer but I hope it is still helpful.
First: In the workspace you make your distribution from, check whether
you really have library icons.
Second: Make the distribution and run it from the partition workshop.
Startup should fail when you do not have the libraries installed. If you
install them later and you can run that distribution then, you can be
sure that you use your library.
Third: Sometimes it is difficult to import the library pex-file into
your workspace when there are already plans with that name. To overwrite
them you can use a traceflag (cfg:c4:14:14:1). But take care! this will
overwrite!!! Do not overwrite them before you put your libraries sources
into another repos. If you did it by accident, at least do not integrate
until you saved the original code.
Hope this helps. If you have more question please feel free to contact
me.

Martin,
Here is how it works:
When you create a library distribution, part of the result is a
'Library
Definition' pex file (located under the 'appdist') like this:
C:\forte\appdist\EnvName\LibName\cl0\generic\LibName\LibName.pex
You would import this pex file into a workspace, after which it
would
appear
as any other Forte library.
Once integrated, the library can used by other plans as a supplier
(remember
to 'install' the library from E-Console).
Hope this helps,

2) You have to programmatically load it using task.part.findLibrary
3) The help says I can "import it into my repository" -- how do I dothat?

How to call a Asynchronous bpel process from a PLSQL procedure?

How to call a Asynchronous bpel process from a PLSQL procedure?

Hi,
You could do something smart and technical very spiffy with soap-stacks in the database and/or dbms_ws/dbms_http. But I allways find AQ with AQ-adapter the simplest. Let Pl/sql enqueue a message on an aq-queue and subscribe an aq-adapter process on it. That can call your async-bpel process. If you want to get answer back in pl/sql, let the aq-adapter process enqueue a response message on another queue or on the same queue with another consumer name. Give it a correlation-id that you provided in the payload of your request message. Your pl/sql process can then do a dequeue on that correlation-id. It will sit and wait until a message with that correlation id is enqueued on the queue.

Martien

How can I disable the Photos app from automatically running when I plug in my iPhone?

How can I disable the Photos app from automatically running when I plug in my iPhone?
I have no intention of ever using Photos, in fact, having to abandon Aperture takes me one step close to moving back to Windows, but I digress.
I just want to NOT have to kill the Photos app every time I plug in my phone.
Thanks.

I am still seeing the option Image Capture, like shown in the screenshot that Rysz posted. But it is another example of the hide-and-seek Apple likes to play with us.
The option has to be set for each device individually. With the device connected to USB, you have to click the tiny disclosure triangle in the lower left corner of the sidebar to reveal the option.
I was perfectly happy with the program I paid for (Aperture), and now to maintain the functionality I have to pay for another application (LightRoom) to get the functionality that I paid for in Aperture.
Aperture 3.6 is working well with Yosemite. I will use it, as long as I have a Mac, that will run Yosemite or a compatible system.
Have you looked at Capture One? It looks much more similar to Aperture than Lightroom.

How to call the form bean value on jsp withthe help of jstl tag
