Ejb client error

Hi, I use jdev 10g. I created a session bean with wizards and after that I created I Ejb client for that bean. When I start the embedded server and run the client java file I get the following error :
com.evermind.server.rmi.OrionRemoteException: jazn.com/admin is not allowed to call this EJB method, check your security settings (method-permission in ejb-jar.xml and security-role-mapping in orion-application.xml).

Anyone has any idea???

hi
There was no problem with that... the AdviceClient is not in the package... I needed j2ee.jar and AdviceAppClient.jar to run the client and hte AdviceClient is in C\java\Projects\Advice directory.... can anyone help me with what is wrong with my first command which didnt work ...
java -classpath c:\Sun\AppServer\lib\j2ee.jar;c:\java\Projects\Advice;c:\java\Projects\AdviceAppClient.jar AdviceClient
This one worked though....
java -cp {$CLASSPATH}:"C:\java\Projects\Advice";AdviceAppClient.jar;c:\Sun\AppServer\lib\j2ee.jar; AdviceClient
I dont know what makes the difference...

Applet as EJB client error

hello
Is it possible to invoke EJB's from signed applets ?
I have signed weblogic.jar and jar of my applet.
APPLET CODE="MyApplet.class" ARCHIVE="MyAppletArchive.jar,weblogic.jar"
WIDTH=600 HEIGHT=400
When applet tries to invoke EJB it throws exception:
java.lang.ClassNotFoundException: weblogic.jndi.internal.ServerNamingNode_WLStub
I think that applet cannot load stub class from server because of security restrictions.
Do you know how to solve the problem ?
thanx
Maris

Hello Maris,
This particular issue that you are facing is mentioned in the WLS documentation.
Basically, you have to take caution when running ejbc (-disableHotCodeGen), and
avoiding the ClassNotFoundException by accessing the InitialContext in only the
thread that deals with applet lifecycle methods (such as start, stop, init, destroy).
Please see the following link for more information:
http://e-docs.bea.com/wls/docs70/applets/usingapplets.html#1075866

Error in running EJB Client on a remote machine

I delploy my beans and can run the EJB Client locally. However when I try to run the Client on another machine, there are errors.
Here is the errors
Syntax error
Out of environment space
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/enterprise/appclient/Main
I have follow the step in the j2ee tutorial and set the env variables according. Here is the bat file I write

runclient -client CBSApp.ear -name CBSClient -textauth
Do anyone facing the same problem with me?
And how can I solve the problems?
This is really URGENT, please help

You are running on Windows 9x or Me, right? The darn OS has 300 or so bytes allocated for environment by default.
Try setting the Initial environment to 4096 in the Properties|Memory tab for the batch file. That will get rid of "Out of environment space". The syntax error is another matter; Windows (except NT and derivatives) shells do not allow '=' in an environment variables value. You cannot overcome that. Some software (Sybase for instance) interprets # as = just because of that. Unfortunately, the JVM doesn't take such an approach.
Better, grab copies of Unix utilities for Windows (www.gnu.org) including the wonderful shell 'bash' and write .sh scripts, which are inherently more powerful.

Java EJB client "Can't connect to ORB" errors...

I'm writing an application that is a Java EJB client application (no web
stuff at all). Needless to say there are no examples of such an app in
the samples dir, they are all web-based.
My problem is that when I try to run my application (client calls a
stateless session bean on the server and gets a "hello world" string
back) I get a "Could not create the TestService bean:
javax.naming.CommunicationException: Cannot connect to ORB [Root
exception is org.omg.CORBA.COMM_FAILURE: minor code: 1 completed:
Maybe]" error.
This is a very simple test, and I'm getting quite frustrated in trying
to figure out what's actually wrong.
Here's the client code (the bean on the server has been deployed into a
module called achptestEjb, the bean name is TestService)
TestService service = null;
TestServiceHome home=null;
String host = "localhost";
String port = "12345";
try {
Properties env = new Properties();
Context context=null;
String jndiName="ejb/achptestEjb/TestService";
System.out.println("JNDI name is "+jndiName);
env.put
("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://"+host+":"+port);
context = new InitialContext(env);
The error comes when the new InitialContext is set with the properties
in the env object.
Any ideas what I'm doing wrong?
It would be a BIG help if iPlanet included one simple pure EJB client
example. There are some of us out here who feel HTML is too limiting
for complicated applications.
Douglas Bullard

I finally found the answer to my problem.... in the Ant script I had
copied from another example, the "-iiop" was lacking in the ejbc
arguments - almost all of the examples assume you'll be calling EJBs
from within the container, instead of a stand-alone client, so they
don't use that flag.
Putting that "-iiop" flag into the ejbc arguments fixed everything.
Thanks, Shivani, for pointing out what is now obvious but was
mysterious.

Thank you for your help info, I soloved the problem.
The problem is the ejb jar was deleted(I don't why)
then System Admin to deploy EJB jar from Admin console.
After that everything is fine.

Hi Albert,
I would double check to make sure the EJB was indeed deployed (check
server log). What message did you see that leads you to believe itwas
successfully deployed? Also, verify the JNDI name you are lookingup in
your client matches the JNDI name for the EJB. If this doesn't solve
the problem, please post the error message and stack trace you are
seeing on the client.

Error Catching Exceptions on EJB Clients

I'm trying to throw an owm exception from an EJB Session to my EJB
client. I can catch the exception but when i use the getMessage()
method the String I receive is not the message I used to create the
exception. The result of the getMessage() call is the same that them
call to printStackTrace().
does anybody knows if weblogic in change the message of the
exception for the printStackTrace before throws the exception to the
client?
Thanks.

Error while running ejbc. Fatal error from EJB Compiler ---- Error while pr

Hi!
I was deploying a test application for a session bean with sun 1 studio 5 and I started getting this message while deploying.
I had tested the bean previously and I had no problems.
I found this in the sun app server 7 release notes, but I don't understand what I'm supposed to do...
"Deployment of CMP beans fails.
The following error is thrown because there are no <query-params> entries in the container-managed persistence (CMP) bean in sun-ejb-jar.xml file:
Error while running ejbc. Fatal error from EJB Compiler ---- Error while processing CMP beans.
Solution
Even if it isn't necessary for the CMP beans, add the query-params tag for finders in the sun-ejb-jar.xml file with the empty parameters."

http://docs.sun.com/source/817-2175-10/decmp.html
Please go to the above docs and look thru the examples given in it.
Example 2
This query returns all products in a specified price range. It defines two query parameters which are the lower and upper bound for the price: double low, double high. The filter compares the query parameters with the price field:
"low < price && price < high"
The finder element of the sun-ejb-jar.xml file would look like this:
<finder>
<method-name>findInRange</method-name>
<query-params>double low, double high</query-params>
<query-filter>low < price && price &lt
high</query-filter
</finder>
I hope this hepls. In your case u just have to make it null.

EJB Client Access From JDeveloper9iR2

I seem to be running into a lot of problems when trying to get a simple EJB client to talk to an EJB on our 9IAS platform. I have developed a simple session bean (just to test) which simply returns a string. When I create the default client code this works fine using the embedded OC4J server in Jdeveloper but I can't run a similar client against 9IAS when I deploy the code. When I go through the client wizard it seems to produce the same code as the standalone EJB OC4J client. I simply changed the name of the server (Context.PROVIDER_URL, "ormi://pe2500/). This is the parameter code I use:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "ormi://pe2500:23891/MyEJBs");
This is the output I receive:

URGENT : ejb client in Oracle 8

We developed a EJB client. This client should be called from an Oracle Database 8.1 (ejb compliant). But, each time we tried to load weblogic.jar, we have several errors into Oracle (ie : ORA-29534 NamingContext could not be resolved)
Do you have an idea why ? Someone already developed an ejb client into Oracle 8.1 ?

They are reccomended because the next step going from your simple single EJB
to anything interesting, like adding more EJB's adding web-apps, adding
web-services etc etc involves ears. If the setup and overhead for an EAR is
easy, then just start there.
But no if you just doing helloworld you of course dont have to ears.

My understanding is ejbc has been deprecated and replaced with appc.Moreover,
BEA is encourgaging developers to deploy ear files. All I want todo is
to use
ant to deploy a jar file with a single EJB in it. I'm not findingthe WL
documentation
very helpful. Hopefully, you'll have better luck than I.

Building an EJB Client

I'm completely confused on how to build an EJB client automagically using Ant.
I have a simple EJB, which I compile using the wlwBuild Ant task. If I set the "ejbgen.jar-settings.ejb-client-jar" property in the project's build.properties, the client jar gets built, but it then ends up in the application EAR file. Worse yet, the generated application.xml descriptor includes the client module. Deploying the ear file fails since WebLogic tries to deploy both modules, and it blows up on NamingExceptions.
I've kludged the process by using wlwBuild and then 'fixing' the resulting EAR file, but that's far from ideal. It works for simple projects, but not Integration projects with the auto-generated very ugly EJB names.
I've looked at wlappc, but the documentation is so scarce I can't tell if this is the tool to use, or how to make it work. Trial and error has gotten me nowhere...:(
So the question is: how can I build the EJB client through Ant without having it end up in the application EAR?
thanks
mike

I'm looking for too and there isn't any.
Here is an example. I hope it could be helpful.

[Jeveloper + EJB client - EJB on OAS] Problem connecting

I having problems getting a simple client from within JDeveloper 3.0(Code snippet - OAS/EJB Client) talking to a simple EJB on OAS 4.0.8.
I have deployed OK (red flag against status?) but when I run the client using port - 5512(ORB port)I get the message below
Anybody any ideas?

Looking for the EJB published as 'MyOASApp/MyEJB'
Naming exception occurred!
Cause: This may be an unknown URL, or some classes required by the EJB are missing from your classpath, or your OAS host is short of resources
Suggestion: Check the components of the URL, and make sure your project includes a library containing the EJB .jar files generated by the deployment utility.

Deploying an EJB Client into 8iJVM

I have attempted several times without much success to load the client for an EJB in 8.1.7.
The difference between this EJB client and others is that it makes calls to BC4J to retrieve data.
The deployment fails with either mismatches in Aurora classes or referes me to loadjava trace file which I can not find.
Having not much success with including the other libraries in the advanced option of loading related libraries, including the JBO EJB runtime, I attampted to load all the jar and Zip files by hand, in this case I got alot of errors relating to the fact that the classes could not be resolved.
Does nay one have any ideas about the correct procedure in loading EJB code in 8.1.7 JVM, which make BC4J calls.
(Note: The EJB code will them make calls to other EJBs which use BC4J for persistace).
Many thanks.
Omeed.

Have you checked how many invalid java objects you have in the database? It may be the JVM was not correctly installed.
I tried to upgrade to 8.1.7 and had 250 java classes that were invalid because Designer R1 was not compatible with 8.1.7.
You can also try to load the EJB by hand and see if that is the problem.

Java Proxy Client Error

I write a EJB client to call the deployed java proxy, but I got the following exception, sounds like
authorization error, but I have already used the xiappluser to access.
Exception in thread "main" com.sap.aii.proxy.xiruntime.core.BaseProxyException:
Error sending MS message. Exception: Received HTTP response code 401.
at com.sap.aii.proxy.xiruntime.core.AbstractProxy.send$(AbstractProxy.ja
va:146)
Here is the my code:
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sap.engine.services.jndi.InitialContextFactoryImpl");
p.put(Context.PROVIDER_URL, "<sid>:50104");
p.put(Context.SECURITY_PRINCIPAL, "xiappluser");
p.put(Context.SECURITY_CREDENTIALS, "****");
Context ctx = new InitialContext(p);

Hi,
We have the almost the same problem, we write a Java Application to call the deployed java proxy, but I got the following exception:
...com.sap.aii.proxy.xiruntime.core.BaseProxyException:
Error sending MS message. Exception: Received HTTP response code 404: Not found.
Anyone have an idea what's happing?
