JSP- EJB Communication

I have a client-server application where my client is an applet and the server is an EJB.
The HTML code to launch the applet is dynamically generated by a JSP page. Now i want this JSP page to be able to communicate with the EJB.
What i need is that the JSP page will pass a parameter to the Applet and the same parameter will be notified to the EJB. So that when the Applet accesses the EJB, the EJB could verify whether the parameter is correct.
Could someone show me a way to achieve this.
I am doing all these bcos since it the applet that acceses the EJB anyone who could manage to get the Applet jar file can access the EJB unauthorizedly,with the help of a decompiler.
If anyone has a better solution to this problem, kindly let me know
regards

Greetings,
What i need is that the JSP page will pass a parameter
to the Applet and the same parameter will be notified
to the EJB. So that when the Applet accesses the EJB,
the EJB could verify whether the parameter is correct.Unless you're using a database to hold the verification parameter you're looking at several problems here, especially if your EJB is a Session Bean. Firstly, if your bean is Stateful (SB) you will get an exception when your Applet tries to access the bean since Session Beans are not shareable among multiple threads (meaning, in this case, "clients"). If your bean is Stateless it can store the parameter internally, however, Stateless beans are poolable. This means when your Applet tries to verify itself there's no guarantee that the bean holding the parameter from the JSP is the same bean the Applet verifies against. However...
Could someone show me a way to achieve this. One way this can be handled is with a "verification" Stateless SB and a temporary database table. The bean can have a method to generate a temporary "key" which it stores in the temporary table and passes back to the caller (JSP). The JSP then passes this as a parameter to the Applet which invokes a method to validate the key. This method would then check the table for the specified key and delete it upon successful verification. However, since you would be embedding a security construct within the web page it is advisable to perform the page loading over SSL...
I hope this helps.

How to call jsp/ejb in webdynpro applications

Hi
Is It Possible to call jsp and EJB in webdynpro applications.If it is please let me know..
Regards
Chandra

Hi,
You can call JSp and serlvets using suspend and resume plugs

http://help.sap.com/saphelp_nw04s/helpdata/en/42/bb8c6cc7131d67e10000000a1553f6/frameset.htm
For EJbs you can create a DTO and try to make use of the model import available in Webdynpro.

Servlet, JSP, EJB

Hi!
I have some general questions about jsp and servlets. I develop an internetbased portfoliosystem which uses ejb to extract data from an oracle database.
q1: How can I create a controlling servlet for page direction?
q2: How can my jsp file connect to my ejb (session bean)? Can I do it directly or must I go through an AccessBean? (if accessbean, how do I do that?)
Sincirely,
Nicolai
Answers/examples may also be sent to: [email protected]

1 For a controller servlet you can use a servlet controller model, ie the presentation logic is in the JSP pages , which submits request to the servlet which does appropriate processing and then redirects the flow to another JSP.
2. Your JSP file can connect to EJBs directly through the remote handle of the bean obtained by JNDI lookups. However the JSP gets cluttered with the JNDI lookup codes.If the HTML programmer is different from Java programmer then go for accessor beans.

JSP/EJB compilation: don't put .java files in EJB jars!

I was having trouble compiling a JSP that uses an EJB remote interface.
          The Weblogic console printed an error like this:
          Thu Aug 31 14:13:58 PDT 2000:<E> <ServletContext-General> Compilation of
          D:\weblogic\myserver\classfiles\jsp_servlet\_hl
          og.java failed:
          D:\weblogic\myserver\tmp_deployments\ejbjar-6787.jar(hlog/ejb/LogEntry.java):5:
          class LogEntry
          is public, should be declared in a file named LogEntry.java
          (source unavailable)
          1 error
          The fix was not to include source files in my EJB jar. Before I was
          using a simple jar command:
          >jar -cf hlog.jar hlog META-INF
          Which of course included both class and source files in the jar (I
          didn't see the harm in this).
          I changed to:
          >jar -cf hlog.jar hlog\ejb\*.class META-INF
          and the problem went away.
          Thought this might save y'all some time and grief...

In the previous message: "I'd putt String as the return value for all methods"...
all methods = doInserir, doAlterar and doRemover.
    public String doInserir() {
        this.produtoRemote.inserir(this.produto);
        return "sucesso";
    public String doAlterar() {

JSPs, EJBs in WebLogic Server 6.1

          Hi everyone,
          I'm starting to develop my first j2ee application. Mainly it is a few jsp pages
          accessing ejbs business logic.
          I would like to implement a security system to prevent anonymous users to access
          the jsp pages.
          It is possible to configure in a descriptor the user information and a profile
          associated with each user, such as read, write, update, delete...? When i refer
          these users i'm talking about the customers that will user the application..they
          are not weblogic users.
          In a few words...i want to implement a basic security system.
          Thanks for your help,
          Best Regards,

          I am trying work with ejb and jsp's using WLS 6.1 but nothing seems to work ,
          with out using jsp if i am invoking ejb's by writing a simple client its working
          fine
          well here is what i have done
          i have copied the ejb remote and home interface classes into WEB-INF/classes generated
          xml files and created a jar file with extension .war
          well now i am invoking jsp by web browser but it gives a compile error package
          not found (where all the ejb classes are there)
          what should be the class path and should these ejb classes and interfaces be in
          c:bea\wlserver6.1\config.....
          path or can they be in any other path

Standard Javabean inside a JSP/EJB application

Hello!
I want to use a JSP-file as a graphical user interface for a j2EE-application. I want to use a standard Javabean as an intermediate connector between the JSP and the Enterprise Java Beans.
Deployment details:
- 2 bean-Jars inside a EJB-module
- A JSP-file inside a .WAR-file
But what about the standard Javabean, where shall I put it?
What are the correct settings in the deployment tool?....
bye from
G�ran, Stockholm

You just need the standard JavaBean available to the EJB as well as the JSP. One nice way is to package such beans into a JAR and include the JAR in the EJB module as well as the WAR as a library.

Exception : JSP & EJB

Hi,
I'm working on a project but it doens't work perfectly.
It use J2EE, EJB and JSP technology but I'm fresh in this field.
At the moment, sometimes (but not for each utilisation and I don't unterdstand why !) there is a Servlet exception which is :
A Servlet Exception Has Occurred
Exception Report:
javax.servlet.ServletException: Cannot create bean of class util.DocumentationServicesBean
Root Cause:
java.lang.ClassNotFoundException: class util.DocumentationServicesBean : java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
     java.rmi.RemoteException: Client not authorized for this invocation.
     at java.beans.Beans.instantiate(Beans.java:211)
     ... ... ...If someone know the reason of this problem, please let me know.
Thanks !

it's not a servlet exception but when ur jsp/servlet is trying to invoke the EJBs, by any means, like creating a new instance, or just getting the pre-existed data by some finder method etc. etc., some times it doesn't have sufficient rights to do that call. Then ur ejb server throws an error, which ultimately comes to the webserver in the form of ServletException.
java.rmi.RemoteException: Client not authorized for this invocation.
at java.beans.Beans.instantiate(Beans.java:211)check ur deployment descriptor for the different roles and their rights, and different methods and permissions for them.
good luck,

JSP/EJB sample-problem

Hi,
I'm having difficulties to get the Oracle JSP sample to wrok.
I deployed the JSP App and also the StackDemo app and changed the envrionment variables as requested .
But each time I try to use the DemoStack bean by submitting a 'create stack' I get the message :
"The requested access method is not allowed for that object"
Can anybody help me with this problem?
Michel.

Alex,
I use OAS 4.0.8.1.
I also reloaded the application after deployment.
I used a clinet snippet that is compiled in JDevelope 3.0 and I run it from there .
It finds THE EJB , ic reated and deployed without giving any error messages. The problem rises the moment I try to use one of the functions of the remote interface of the EJB. In these functions I try to use functionality of viewObjects that are provided by a bussines component that I generated using JDeveloper 3.0.
The wrb log file mentions a 'null pointer exeption'.
I think that I do something wrong when initializing the application module that wraps the business component, but I can't see what is wrong.
This is the code I use in my EJB :
String theAM = "EDMpackage.EDMAppModule";
ApplicationModule root = null;
String sessionDefName = ApplicationModule.DEFAULT_DEF_FULL_NAME;
Hashtable env = new Hashtable(2);
env.put(Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
try
Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(sessionDefName);
root = home.create();
catch(Exception e)
e.printStackTrace();
localAppMod = root.createApplicationModule( "EDMAppMod",theAM );
This works fine , but when I try to get a ViewObject through the localAppMod, I get the error. So I think I am wrong somewhere here.
Michel.

JSP, EJB in Jboss 4 with mySQL database. Error in connecting to database

Hi, i using JBoss 4-0-1 with jsp and mySQL database. I get this example from a book using stateless session beans. However i modify it so it can connect to mySQL database.

     recording titles once, we place this code inside

Simple JSP/EJB demo app

Hi
Is there a demo application with a JSP interface to EJB in middle tier without ADF, Struts or anyother frameworks ?

Ejb client to ejb communication- slow performance ?

I think BEA has a very nasty implementation of ejb client to ejb server communication.
When a client looks up a an ejb component it gets a t3client eastablishing a socket connection to the ejb server (WL server).
For one client VM there is one such client and all ejb client to server packets go through this one socket. To me it seems to be a major bottleneck for performance.
Any body has any info ideas on how to get around this.

What makes you think it's a bottleneck? It nearly always greatly improves performance.

JSP + EJB + IE + resize = lock exceptions

I'm getting odd behavior when I resize IE 5.5 with a Servlet/JSP loaded
          that references some EJB's. I'm getting dozens of page reloads, followed
          (eventually) by the server getting lock exceptions thrown from the
          EJB's.
          I've tried adjust the HTTP headers to allow for caching, but that
          doesn't seem to help. Does this sound familar to anyone?
