Updating EJBs from JSPs

i'm looking for a way to udpdate several entity beans via a stateful session controller.
I can create references to the ejb controller in the JSP without a problem, but i need to know how to accept data entered into a form, store it temporarly and then call a ejb controller method using the form data as the arguments.
i have seen the use of javabeans in this type of situation but i have limited time and i'm trying to avoid having to create event logic to signify that the javabeans' properties have been altered.
ideally i would like to use the data entered into the form as arguments in a direct call to the ejb controller method.
any advice would be appreciated!!!
Thanks,
Student with a deadline!

Hi,
You can get the instance of any bean inside the jsp as long as you have the correct url of the application server and ejb jndi name. Once you created the EJb instance, you can pass those form data, which you have to get using getParameter() or from httpsession and call the ejb as if you are calling EJB from normal java program.
Hope that helps.
Best Luck!

Calling an EJB from jsp - ServletException

I am unable to call an EJB from jsp, unless I put the actuall classes of

          where result.jsp is the jsp page calling the EJB. I did an import of the

          like i said, it works if I put the bean classes in the classpath. But is

Did you package your JSPs in a WAR and your EJBs in a JAR and package the
          WAR and JAR in an EAR? That is how to do it in 6.0. Works well.

EJBs From JSPs - Tutorials?

Hi all,
I've just been given a task, and I don't know where to start. I've been given an EJB and I need to write a web front end to test it (JSP). Now if it was a plain JavaBean, I know how to do it. But I know EJB's are different.
Could somebody point me in the direction of a good tutorial about accessing EJBs from JSPs. I'm using WebLogic as my application server, so something relevant to that would be nice.
Cheers for any help.

To put it in "idiot" terms:
Think of your EJBs as people you want to ring up on the phone. You know their name, but not their number. How do you do this in real life? You use a phone book, using the person's name as a reference, which will lead you to the right number to dial.
The phonebook in this paradigm is JNDI - the naming and directory interfaces.
The name you use to look up is how the EJB is bound (ie, "java:comp/env/ejb/MyPerson", or "foo/bar/beans/MyPerson"). You define this name (the phone number) in the deployment descriptors packaged with the EJBs in the jar file.
You access the phone book (in your JSP or some other bean in your webapp) by using a Context.
ie:
Object objRef = initialContext.lookup("foo/bar/beans/MyPerson");
Then you ask the context for the person's home information:
MyPersonHome home = (com.foo.interfaces.MyPersonHome)PortableRemoteObject.narrow(objRef, com.foo.interfaces.MyPersonHome.class);
Once you know where they live (you have their Home information), you can ring them up (create them, search for them, search for a singular one)
MyPerson bill = home.findByPersonNameInHouse("billy");
once you have Billy in your possession, yu can perform business logic on him:
String stats = bill.getStatistics();
// get rid of bill permanently
bill.remove();
That should be enough of an introductory paradigm. You will need to follow along the tutorials and other many documents to understand exactly how things are bound (phone numbers are listed) and so forth.
Good luck!

Calling EJB from JSP

Hi - I'm running OC4J 9.0.2 on windows 2000
I have a JSP that accepts user inputs and the call respective Servlets. Before the servlet gets called, I want to log a tracing event with an EJB(Stateless Session Bean).
I have manipulated the "form" values with JavaScript but cannot find any docs on how to call an EJB from JavaScript in a JSP.
The JSP and EJB works fine on there own. How do I get the "form" values into the EJB variables without JavaScript?
The EJB logs fine while still in the "JAVA" part of the JSP but I don't know how to extract these 2 index values.
Tks

Hi Christian,
A few questions to clarify where the cause of the problem might be:
1. When you run the JSP app in JDeveloper, are you connecting to the remotely deployed app module, or the local one in your workspace?
2. In your JSP project, there is an appmodule.properties file. This file should specify the connection mode to use to connect to your EJB (ConnectMode=EJB), and should be deployed to a directory on your webserver's classpath, along with the connections.properties file. If the appmodule.properties file contains the wrong connectmode setting, or is not on the classpath for the webserver, this might be the cause.

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.

How to lookup an EJB from JSP on a Remote Server in JES2005Q4

Hi,
I am having two different domain (domain1,domain2) respectvely. My ABC.ear j2eee application is deployed on domain2 and its iiop port is 33703.In domain1 i have xyz.war (web application) and it's IIOP port is 3700 .In xyz.war i am having CallEJB.jsp file.In this Jsp file i want to lookup an EJB Service called PaymentEJB(JNDI Name is ejb/PaymentEJB).
The code is below
InitialContext context=new InitialContext();
Object objRef=context.lookup("corbaname:iiop:andaman:33703#ejb/PaymentEJB");
I am getting the following error.
[#|2005-12-14T16:42:03.422+0530|SEVERE|sun-appserver-pe8.1_02|javax.enterprise.resource.corba._DEFAULT_.rpc.transport|_ThreadID=11;|"IOP00410216: (COMM_FAILURE) Unable to create IIOP listener on the specified host/port: all interfaces/3700"

at com.sun.corba.ee.impl.logging.ORBUtilSystemException.createListenerFailed(ORBUtilSystemException.java:2661)
My doubt is
1.While starting domain1 and domain2 iiop listeners are started on the port 3700 and 33703.in that case why EJB lookup tries to create listener on one more time.
2.I am looking the 33703 port only.but it tries to create port on 3700 why?
3.It was working till JES2005Q1.Is there any patch i need to install? or i need to change anything in my code.
I am frustrated with this error for past one week.I will be happy if some body will give me the peace of mind(thru some solution).

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

Insert data into table from JSP page using Entity Beans(EJB 3.0)

I want to insert data into a database table from JSP page using Entity Beans(EJB 3.0).
1. I have a table 'FRIENDS', (in Oracle 10g database).
2. It has two columns, 'NAME' and 'CITY'. Both have datatype strings(varchar2).
3. Now from a JSP page, having two textfields, 'NAME' and 'CITY', I want to insert data into table 'FRIENDS'.
4. In between JSP and database is a Entity Bean(EJB 3.0) and a stateless session bean.
5. I am using JDev as editor.
Please provide me code ASAP or link with similar example.
Thank you.

Hi,
I am also trying that scenario. So u can
Post the jsp form data to a Servlet which will act as a Controller.
In the servlet invoke the business method.
Similar kind of app is in www.roseindia.net
Hope this would help u.
Meanwhile if u get any optimal solution, pls post it.
Thanks,
Happy Java Coding.

That's the code that you need to execute but you should
probably encapsulate that code in Custom Action.
Orion has a EJB Tag Library that is free to distribute that
does all that stuff you just set some attributes.
Go to their site and look at their Tag Libraries.
Also look for other Tag Libraries Freely Available for EJB Access.

How to do a JSP talks with my "EJB from tables" ?

Hi !!
I'm new to Jdev.
I have built a database, using MySql, and I also have built EJB from my tables.
My EJB are Entity Beans and I have used the Wizard to create it from tables of my data base.
Every EJB is working well and I have a simple JAVA client application which can use my
beans to edit data in my database.
Now I need create JSP pages that will use my beans, to edit my database too.
So, I have created a new project and in this project I have built a JSP page, in the same workspace
that has my beans' project.
But I don't know what must I do to put my JSP page connected with my beans.
1) What must I do?
2) Is it possible to put a JSP page talking with a Entity Bean, or it will be necessary to create session beans?
3) Is my beans' project a BC4J project? If not, how to change my beans' project to this goal?
Any hint will be very helpful?
Thanks.
Rodrigo Pimenta Carvalho.
Brazil.

There is a new feature to support this in the 9.0.3 preview release.

How can I access to an EJB from a JSP, using a taglib?

I'm trying to access to an EJB from a JSP using a taglib,
          and I get the example in
          http://java.sun.com/j2ee/j2sdkee/techdocs/guides/ejb/html/Advanced5.html.
          But I colund't run this example because in the weblogic Log appears many
          errors when I run the JSP.
          Can you help me?


Backing files is an option. If you need to do it from the controller, you
could use the Forward object. The forward object constructor can take a URL
object as a parameter. This should do the trick.

Hi, you have to use backing file to get what you want. In my case, I am
using a page backing file. Perhaps a portlet backing file can do thatalso.
Cmiiw, the redirect header makes the page redirected only if the httpheader
has not been sent to client. In your case, the header has been sent (i.e.
the portal header.jsp has been displayed, etc). So the header need to be
sent before anything else sent to client browser. This is where thebacking
file comes handy.

I tryed the same trick with a simple JSP, and that's ok, but portal

Please could you tell the correct way of redirecting the whole browser

How to use EJB in JSP...urgent!!!

hello,
i am novice programmer in EJB.
i am using weblogic 6.1 ...
my problem is how to use EJB in jsp page.
my code is as follow..but its not displaying any result.
<%@ page import="javax.naming.InitialContext,
javax.naming.Context,
java.util.Properties,
firstEJB.First,
firstEJB.FirstHome"%>
<%
     long t1 = System.currentTimeMillis();
     System.out.println(t1);
     Properties props = new Properties();
     p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.TengahInitialContextFactory");
     props.put(Context.PROVIDER_URL, "localhost:7001");
     Context ctx = new InitialContext(props);
     FirstHome home = (FirstHome)ctx.lookup("FirstEJB");
     First bean = home.create();
     String time = bean.getTime();
     bean.remove();
     ctx.close();
     long t2 = System.currentTimeMillis();
%>
<html>
     <head>
          <style>p { font-family:Verdana;font-size:12px; }</style>
     </head>
     <body>
          <p>Message received from bean = "<%= time %>".<br>Time taken :
          <%= (t2 - t1) %> ms.</p>
     </body>
</html>
please tell me the solution.

Hi, I don't know if it may be the cuase of your problems, but you should narrow the Object obtained doing the lookup, like this:
FirstHome home = (FirstHome) PortableRemoteObject.narrow(ctx.lookup("FirstEJB"), FirstHome.class);

Problem for ResourceBundle calling from jsp file

Hi, I am using WebLogic 5.1 in Solaris 8
          I use java.util.resourceBundle to get the information from a .properties
          file
          I put the properties file in /opt/weblogic/myserver/serverclasses
          When I call the properties file from EJB, It seems to be OK
          But when I call the properties file from JSP using the same script, It said
          the properties files not found
          The Error message is:
          <ServletContext-General> Servlet fail
          ed with Exception

Hi,
open dataset file for input in text mode.
check sy-subrc = 0.
while sy-subrc = 0.
read dataset file into wa.
if sy-subrc = 0.
append wa to itab.
else.
    exit.
endif.
endwhile.
close dataset file.
regards
Siggi
PS: check also the F1-help for open, read and close statements!
