Applet calls EJB

Now I want to use an applet embeded in IE to call an EJB on the server.
They worked well in JBuilder6.0,and there are:
test.html
eb/*.class (the classes of EJB)
ebaptest/test.class (the class of applet)
Generated Source/*.class (some class made by JBuilder)
under the directory %JBuilderworkingdir%/classes.
But I want to deploy them to weblogic6.1,and how to do that.
I've tried many methods,and failed.
After I input "http://localhost:7001/test.html" in the IE,then the message "javax/ejb/EJBHome not found" is displayed.
pls help me,THX

Although I've used applets and EJBs together, through servlets, I've not done it directly.
I suspect that what is happening is that our applet, when deployed outside of the JBuilder environment, cannot find the j2ee.jar, which contains all of the javax.ejb.* classes and interfaces.
Make sure that this jar file is in your applet's codebase. That should fix it.

Calling EJB from an applet in 9iAS Release 2?

Hello!
In 9iAS Release 1 it is not so easy to call an EJB from an applet. First the applet needs special privileges and then the applet starts only once. The cause of problem is the implementation of ormi.
Will 9iAS Rel. 2 support Applets calling EJBs?

Jeff,
I am also trying to make an applet client for an EJB deployed to OC4J.
I modified the java2.policy file as you suggested, but when I tried to run my applet, I
got the following error:

Calling EJB from applet

Hi friends,
I have a problem of caling EJB from applet.that too from browser.
Through dos prompt,I am able to set the classpath and then open the applet and then call the EJB.but thru browser i am encontering two problems,
First,The codebase of applet is not being set and i am unable to view the applet.
Second,my Initial Context Factory is not being found it is giving error as
Cannot instantiate class: com.evermind.server.rmi.RMIInitialContextFactory.I am using oracle app server Oc4j2.
can any one help me out.
i am able to get output thru dos prompt where i can set classpath

kyren,
he has used something called HTML ConvertersDepends on the version of the plug-in you are using.
(I'm sorry, but I couldn't find that detail in any of your posts!)
You have to use the (HTML) converter with java version 1.3 (for example), but you don't have to with java version 1.4.
thru my jbuilder version i am able to solve my
problem.
but thru browser,i am first of all not able to
display applet.That's because "JBuilder" uses the appletviewer to display the applet (and not a browser).
I Think for normal displaying applet we don't need of
signed or unsigned applet.when calling ejb we may
require.As Anupama has stated, the "codebase" attribute of the applet tag must be relative to the directory where the HTML file (containing the "applet" tag) is located. Where I work, we also use the "archive" attribute that tells the applet where to download the JAR files from. In order to lookup your ejb from your applet, you need (at least) the "oc4jclient.jar" file.
By the way, if you want your name to appear next to your posts (instead of your ID number), you need to update your profile. Click on the "Forum Settings" link at the top of the (Web) page.
Good Luck,
Avi.

Call ejb from browsers

Hello Developers!
I deployed my ejb to OAS4081. I call that
from JDeveloper so it good. But when I try
to call from applet in IExpl5 I can't
instantiate the ORB. I've got a com.ms.security.SecurityException : oracle.oas.orb.CORBA.ORB.init
I coded the CLASSPATH(oasoorb(yoj),client,
ejbapi...) perfectly, I think.
If anybody could help, please...
Thanx!

Hi there,
          I saw someone on this group had a problem to locate proper classpath
          to call EJB from JSP. I thought if you call EJB from classpath, you are
          calling the bean. But you loss all the EJB functions. To be able to utilize
          EJB features like object pooling. You need to call it from Weblogic server
          using url/jndi, not from the jar directly.
          Any comment? Am I right?
          BTW, my question about calling EJB from JSP means calling through URL,
          not a local path.
          Thank you

Applets to EJB Cluster

Hi,
          Is the following true? If so what is the recommended way to load balance
          EJB calls from applets?
          Since applets (not signed) can only create a connection to the server they
          where downloaded from, I can not call EJBs that reside in a WL cluster.
          These EJBs may reside on a different machine other than the one the applet
          was downloaded from.
          Can I solve this by installing a Web Server on each of the machines in the
          cluster and have the applets stick the one machine? What I do not like
          about this scheme is that I loose the dynamic load balancing features of WL.
          Any help will be appreciated,
          Assaf Pazner


               The WLS RJVM scheme supports routing / session concentration of
          request. Thus, using clustered services within the applet security
          model or over a firewall should work fine. The server that the applet
          talks to will route requests to the appropriate server within the
          cluster.
                                        - Mike

Applet and EJB

Hi! there.
I use applet to get Bean from EJB.
when I lookup jndiName from context. I get following exception ,
java.lang.ClassCastException : weblogic.rmi.internal.StubInfo
How I can obtain EJBean from context in applets?
any reply is appreciated.
I use wlServer 6.1sp1, and I use java plugin1.3.1_01
I used following applet code
<html>
<OBJECT CODE = "Test.class" CODEBASE = "t3://localhost:7001/applets" ARCHIVE =
"weblogic.jar, micDcdpApprovalEJB.jar, micDcdpSystemEJB.jar" WIDTH = 500 HEIGHT
= 440>
</OBJECT>
</html>

Of course can.
You should call EJB remote interface.
This will help you

Calling EJB 3.0 from ALBPM

Hi,
I tried calling EJB 2.1 from ALBPM and it worked.
But I was nto able to call EJB 3.0.
Is calling EJB 3.0 supported from ALBPM 6.0.2?
If yes, how to call a business method in EJB 3.0?

Frank,
Thanks. The @LOB annotations are missing.

EJB 2.1 session bean calling EJB 3 session bean?

I have a WL 10 (JDK 1.5/EE 5) server that has several EJB 3 stateless session beans deployed and working well. But now I need to allow a JBoss 3.2.3 (JDK 1.4) EJB 2.1 session bean make remote calls into these EJB 3 EJBs. Can this even work?
It seems to me that EJB 3 calling EJB 2 would be fine, but not in the reverse?

Java Applet call javascript problem

Hi I have a web page as follow and embedded a applet. The applet call the java script, and instead of showing an alarm, the browser show the javascript code. Is that strange ? Any suggestion for this problem.
HTML:
================================================================
<HTML>
     <HEAD>
     function ShowEmbd()
          alert("Test Applet call Javascript");
     </SCRIPT>
     </HEAD>
     <BODY>
     <FORM NAME="AppletEmbdStart">
          <OBJECT classid="clsid:48B2DD7B-6B52-4DB0-97C9-ECB940113B47" id="CIVON_DEmbdObj" width="0" height="0"></OBJECT>
          <APPLET code="MyApplet.class" width="0" height="0"></APPLET>
     </FORM>
     </BODY>
</HTML>MyApplet.java
=========================================================================
import netscape.javascript.*;
public class MyApplet extends javax.swing.JApplet
     private JSObject m_win = null;
     private JSObject m_doc = null;
     public void init()
          getJSWin().call("ShowEmbd", null);
     private getJSDoc()
          if(m_doc == bull)
               m_doc = (JSObject) getJSWin().getMember("document");
          return m_doc;
     private JSObject getJSWin()
          if (m_win == null)
               m_win = netscape.javascript.JSObject.getWindow(this);
          return m_win;
}The page was load and it should call the applet MyApplet. The MyApplet should do the init() method and call the Javascript "ShowEmbd()", BUT, instead of show alert from ShowEmbd(), the browser show the code of ShowEmbd() itself ...... It did not run the javascript and shows the alert ??
The browser shows a message from status bar "The applet not initial" ???? why ???
Can anyone help ?!

On first look:
I am not sure about the Object Tag, but the Applet Tag requires the MAYSCRIPT attribute before Java can call Javascript.

WDP calling EJB and passing objects of classes from Java project

Hi.
We have <b>Java</b> project which contains some classes common for all projects (like xxx.Version).
We have <b>EJB</b> project which defines EJB interface using these common classes (like getVersion(String,int): xxx.Version and getCurrency(String,xxx.Version,int):xxx.Currency ).
We have <b>Web Dynpro</b> project which calls EJB:
1. Lookup is successful
2. call to getVersion is successful
3. call to getCurrency fails with <b>NoSuchMethodException</b>:
xxx.XXXObjectImpl0.getCurrency(java.lang.String, xxx.Version, int)

How can I set dependencies to get this running?
Thanks to all
       Volker

Hi,
Is it available in the interface you are using..
If the answer is yes.. you might have probably forgotten to deploy the EJBs ear file after making the changes..
Rebuild it.. and deploy the EJB s ear file again..
It will solve the problem.. If that also does not work,it might be a problem with the cache.. restart the server..
It should work now !

How to Call EJB from coldfusion

I need to call EJB that's created in JBoss from coldfusion.
I'm getting different errors depending on how I set the home object
and provider url.
If I prefix provider url with jnp://, then I get the
following error
The connection to the remote JNDI server on host jnp at port
1099 has failed (as have all backup hosts listed, if any) - please
verify that the server is running and the NamingService is
available
If I take the jnp out and keep just the ip address and port,
then i get the following error
null (no security manager: RMI class loader disabled).
So I'm not sure what the issue is and I haven't used this
feature before.
Here's my code

I tries to call custom EJBfrom custom component received
follwong error
ERROR [STDERR] javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
No ClassLoaders found for: com.mycom.myapp.action.interfaces.pm.ejb.PmFacadeRemote
(no security manager: RMI class loader disabled)]
any idea?
Thanks

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.
