Problem in accessing the ejbs

HI ,
I am New to EJB. Here i am getting a problem n accessing the resoucess which are deployed in weblogic. Here i want to access the resoucess from a jsp. So i declared a web.xml. In that what i need to write. can anybody help me what i can specify in web.xml
Thank you.

Stop asking the same question again and again. It will decrease your chances of actually getting some help, because your rudeness will make people angry and less inclined to help.
Your whole approach sounds wrong, but that's your problem. I'm betting that you don't need EJBs. You shouldn't write JSPs without JSTL. Totally, utterly wrong.
But if you insist, I would recommend that you actually get a book or some documentation that shows you how to call an EJB from a web app. Since you're using WebLogic, maybe reading their documentation will help:

Problem in Accessing the EJB

I want to access remote EJB from my Portal Service.
the EJB and the portal Service run on a separated machines.
here is what i wrote:
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sap.engine.services.jndi.InitialContextFactoryImpl");
properties.put(Context.PROVIDER_URL, "p030633:50004");
InitialContext context = new InitialContext(properties);
String name = "sap.com/GDS/GtinManager";
GtinManagerHome home = (GtinManagerHome)
javax.rmi.PortableRemoteObject.narrow.narrow(
context.lookup(name), GtinManagerHome.class);
gm = (GtinManager)home.create();
i run this code from java application and it works.
but in portal i get this error:
"com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at GDS, the whole lookup name is sap.com/GDS/GtinManager."
Thanks

Hello,
if you NW 04 SP7 or higher, please look this document
https://www.sdn.sap.com/sdn/index.sdn?contenttype=url&content=/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/how to access an ejb from a portal component.mht
else in EP6 SP2, it is more difficult to access to an EJB because the portal have an other classloader sysem and other JNDI context

I cant properly utilize that..
So please help me with steps regarding that,,
for javabean
and if any , for EJB also..
with regards
Kishor.G

HI,
Since webdynpros follows Model View Controller Architecture You can access EJBs in webdynpro(views/frontend) infact to connec to database uding JDBC you have to utilise EJB ( opening connection to database closing, and other Business functionality).See this link

Use the PACKAGE SIZE oprion of the SELECT statement:
LOOP AT t_cdobjid.
objectid-low = t_cdobjid-cdobjid.
objectid-sign = 'I'.
objectid-option = 'EQ' .
APPEND objectid.
CLEAR objectid.

Q<ADVC-27> How do you pass the security info to access the EJB?
A<ADVC-27> Authentication for web service users must occur at the web layer. This
means providing appropriate web resource definitions and restrictions in the web.xml
file for your project. The most common and useful form of security for application
interaction is via client-side certificates. Then the client identity is transmitted
to the EJB is the same way as in regular J2EE environments. There is a complete description
on security on e-docs:

Having problem access the EJB 3 from Web Component

Hi ,
I have an EJB 3 entity AuctionItem and a session ItemProcessor only implements the local interface IItemProcessor, then I use a servlet to access the findAll method in the ItemProcessor. I've created a Enterprise Applicaiton project to contain the ejb jar and the war file, but after I deploy the ear successfully, I couldn't access to my servlet through http://localhost:8080/AuctionWeb/AuctionServlet, it keeps giving me error like follwoing. Do you know why, your help will be very appreciated !

The most common reason for this failure is if your web.xml does not refer to the latest web application
.xsd :
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http
://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/x
ml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
Otherwise, the web application is considered to be a J2EE 1.4 application and annotations
are not processed. If that's not the case you can also run the application through the
verifier to see if it identifies any issues.

Problem in accessing the Interactive forms in an ISR Senario(like MSS)

Hi all,
I am facing a problem whenever I try to access the interactive form.I am doing this from the standard Business Package, MSS.
I have done all the configurations needed for these ISR Senarios.
I suspect the the error is because of some missing IMG customizing.

}When i try to access the bean it's throwing a communication exception. The exact stack trace is:

Thanx in advance.

when i change the properties url attribute to jnp://localhost:1099 like
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");It's throwing unmarshall exception:

Problem in accessing the Oracle DB Express Edition homepage

Hi,
I installed the Oracle database express edition on my computer. I have no problem accessing the website when I point to the URL using the localhost : (Eg., http://127.0.0.1:8080/apex/ or http://localhost:8080/apex/ both work fine). But I am having problem accessing it using my network ip address or machine name.
(Eg., I cannot access it when I use the URL http://mymachine:8080/apex or http://10.130.1.17:8080/apex) . What should I do? HAve I missed out some configuration steps?

Have you checked on the remote access option?
There's also a forum dedicated to Oracle Database Express Edition (XE) questions.
C.

We want to deploy Servlet/JSP in JServ and call the EJB's deployed in iPlanet App Server 6.0 SP2. How do we make the getInitialContext Call be able to access the EJB's.

Additionally what configurations do we need to make sure we have on JServ (Third party Servlet container) to make sure that the iPlanet EJB's can be accessed.

Let me preface my instructions with the comment that this isn't a good idea. Although the J2EE specification allows you seperate your web container from your EJB container, in practical deployments it is a bad idea. The overhead of doing RMI/IIOP calls to an external container as opposed to making inter-JVM calls means that you can expect roughly an order of magnitude less performance than if you colocate your web and EJB containers. (This is why all EJB containers are also web containers, or at least have the provision to install themselves in the same JVM as a web container.)
That said, if you do not have the option to move the servlets to iAS, you can access EJB's in iAS from JServ the same way that you would from any remote client. Take a look at the following information for more detail:
Chapter 9 of the developer's guide ( this shows you what changes you need to make to the remote JVM (at JServ) and in the EJB's that you are exposing).
The RMI/IIOP sample application. This gives you an example of how to access EJB's from outside the container.
(To answer your direct question, the following code will get the initial context. But if you don't take all of the other configuration steps, this code won't work:
env.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://" + host + ":"+port);
Context initial = new InitialContext(env);
I'd also suggest that you approach the task with the following approach. (Assuming that I haven't managed to convince you that this is a really bad idea.)
1. Get your EJB's working on iAS. Test them with servlet harnesses running on iAS.
2. Get your servlets working on JServ, if they aren't already.
3. Create a simple standalone Java application as a test harness for EJB's. Follow the RMI/IIOP instructions until you get this test harness working.
4. Create a simple servlet test harness in JServ to access your EJb's. Follow the JVM setup instrucitons until you get this working.
5. Actually integrate the EJB's with your production application.
I say this because there are about five trillion things that can go wrong in this process. Although the troubleshooting steps in the docs are helpful, I find that it helps to get one thing working at a time. It's very frustrating to spend a day trying to resolve JNDI issues only to find out that you have your CXS configured improperly.

Problem in accessing the media files from another server

Currently I am working in a project with streaming video on demand and using FMS 4.5.
Let’s say the FMS is installed on one machine say ‘121.123.35.34’ and there is another server ‘100.54.88.222’ where all the media files belong. Now we need to point to this third server to play videos from FMS.I have done the below changes:
In the fms.ini file: set the VOD_DIR2 = \\100.54.88.222\myvideos
In the application.xml: Added the stream: <Streams>/hr;${VOD_DIR2}</Streams>
From my application accessing the path of flv as:source= “rtmp:// 121.123.35.34:1935/vod/hr/test” . Not able to access the video.
Note: If I will point to say ‘C:hrvideos’ in VOD_DIR2, then I am able to access the videos using the same URL.
I also tried mapping the shared path to the FMS machine and then given the mapped drive path in the VOD_DIR2, but this also doesn’t work.
Please let me know:
If we need to configure any other parameter to stream videos from another server.
VOD_COMMON_DIR: I modified this similar TO VOD_DIR to location 'C:hrvideos', I am able to stream the videos using rtmp, but not abl eto stream with http.
          Please let me know can we stream using http also as we need this to run f4m manifest file.
          http://121.123.35.34:8134/vod/hr/sample.mp4.
          http://121.123.35.34:8134/vod/hr/sample.f4m
Thanks,
Anjali

Hi Shiven,
I followed the steps suggested by you:
1) Changed the stream:
<Streams>/hr;${VOD_DIR2}</Streams> to<Streams>/;${VOD_DIR2}</Streams>
But not able to access the video with rtmp:// 121.123.35.34:1935/vod/test
2) For http streaming, changes the HttpStreamingContentPath in hds-vod in the httpd config file, and tried to stream the video like:
http:// 121.123.35.34:8134/vod/test.mp4 or
http:// 121.123.35.34:8134/hds-vod/test.mp4
But not able to load the video.
Please suggest?
Thanks & Regards,
Anjali Rawat

Problem in accessing the Web Service using standalone Java Client

Dear Friends,
Hi,
I have an active web service and I have tested the same with XML Spy and Apache Axis and is giving me the output perfectly. For the same, I have developed a standalone Java client but getting problem in fetching the output.
The Exception is :
<Jan 4, 2006 5:54:16 PM GMT+05:30> <Info> <WebService> <BEA-220025> <Handler weblogic.webservice.core.handler.ClientHandler threw
an exception from its handleResponse method.
The exception was:

I have tried some ways to set the content type explicitly but the results are same(throwing an exception).
I appreciate you all for helping me out of this.
Thanks
VR

Hi Amit
We also have this issue with weblogic webservices. Did you get any resolution for this issue.
When the service is executed for lesser number of hits, all the responses are processed properly. But as load (Number of hits for the same service) increases, few responses are failed to be parsed in the web service client. We could confirm that the producer responds with proper content type (text/xml)
Any help or pointers will be greatly appreciated.
Thanks,
Finny
