How to use EJB 3.0 in Visual Pack Web ?

Hello everybody !
is there someone who can explain me how to bind a TABLE component visually with a particular business method of an EJB.3.0 (in Netbeens 5.5 / Visual Web Pack)
-Is there a way to do the same thing as we can do it in Sun Java Studio Creator ?
-otherwise is there a tutorial / example / resource on the web witch can help me resolve this problem ?
thanks

I have a similar question: How can you set up entities and persistence units when working in a visual web project created using the Visual Web Developer pack?
Perhaps the Visual Web Developer pack could use a couple of sample projects showing how these things are done.

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,

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);

How to use a deployable proxy to consume a web service?

HI Gurus,
I am following this article below which helpfully explains how to create a proxy. So far so good. I have been able to create a proxy. However, the article only describes how to build a proxy.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70c7d0f7-153d-2a10-5d96-d334b67cd771
In the concluding part of the document the author says "In my next article I will tell you how to use this deployable proxy to consume the web service in web application."
I have looked around the SDN but have not been able to get the next part of this document.
I have a JSPDynpage application which is required to consume a webservice. I want to use this proxt to consume the webservice.
Any help or any other document that explains how to use a deployable proxy to consume a web service will be helpful.
Thanks,
SB

How to use ejb control in jsp

hi,
I created an entity bean and I created an ejb control. Now I would like to
use this ejb control inside of a jsp (no page flow).
When I use the ejb without the control I do the follwing steps :
- get the local home
- call finder methode
- get the local object
- call getMethod() and display content
Can someone please post an example how to use the netui-data tags to do this
steps or do I have to use the controls in a total different way?
Can someone please tell me how to use the ejb control inside a normal java
class?
Michael

Do you want to use taglibs or develop custom tags? Either way take a look at these:

Well, I've never used a JProgressBar before, so I'm

How to Use SOAPArray to Exchanged Data with a Web Service

The method of a prototype Web service I created is defined to take many parameters
and return an object of a user defined class. Furthermore, the user defined class
includes data elements of another user defined class and the Java ArrayList class.
This works with a Java client referencing the WebLogic created client.jar file
but I don't know how well it will work with a non-Java client. In particular,
with Perl which is the language that will be used by the developer who first will
test with the prototype.
In posts to this newsgroup use of "language-specific, generic containers" has
been discouraged and the "language-agnostic" SOAPArray recommended. I have searched
this newgsroup and the Web for examples of how to use a SOAPArray in a Web service
EJB to receive parameters and return results but found none.
Will someone refer me to an example or give an overview of how a Java Web service
EJB running in WebLogic 6.1 would use SOAPArray to get parameter values and return
results?
Also, I would like confirmation that it is best to use SOAPArray to exchange data
with a Web service to achieve the goal of a service accessible by any language.
Thank you.

Replies in-line:
How are the structures, e.g. gltrans-workType, defined in the Web service?The structure is made up of nested Java Beans, but this does not mean that the
client for your web service has to be written in Java. The WSDL that I sent contains
everything that a .NET-based (or Perl-based, or Python-based, or VB-based, or
C++ based) Web Service Stack needs to correctly create all the data types in the
web services' signature! That's the beauty of XML Schema! It's programming language
independent :-)
In
other words, what definition in Java resulted in the WSDL statements?The WSDL wasn't produced by WLS 6.1, but it (WLS 6.1) can consume it.
What is the signature of method submitGLTransWorkAsJavaBean() in the
Web service?public void submitGLTransWorkAsJavaBean(GlTransactionsCpyType glTransactionsCpyType)
GlTransactionsCpyType is the outer-most Java Bean. WLS 6.1 does not generate
Java Beans for you, but it will use ones that you defined. See the Java Bean tutorial
on the Javasoft sitem for details on how to create a Java Bean.
Was the WSDL generated using the WL tools for creating a Web service?No.
Conclusion:
You asked for someone to provide you with an example of how to use SOAP array
in a WSDL, which is what the attached file contained :-) What you want to do now
is find a tool that can generate Java Bean code from this WSDL (Apache Axis has
a wsdl2java tool that should work), or create the Java Beans yourself. Afterwards,
create a WLS 6.1 Web Service a expose it for a Perl or .NET client.

Hi Jeff,
Sounds like a pretty cool prototype :-)

How to use user-defined packages in JAX-RPC web service

I am trying to use Object of my class located in my package in jax-rpc webservice,the code is
package supercomputer;
import Hello.*;
public class SuperImpl implements SuperIF
public String sendParam(String data)
Temp ob=new Temp();
int i=ob.get1(10000);
return data+"returned by supercomputer";
Temp is located in Hello package,I have jar the Hello package as Hello.jar and has set its classpath in targets.xml of Ant tool.
The code compiles well and service is deployed successfully,but when i try to call the service from the client its gives me following error.
[echo] Running the supercomputer.SuperClient program....
[java] java.rmi.ServerException: Missing port information
[java] at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:357)
[java] at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:228)
[java] at supercomputer.SuperIF_Stub.sendParam(SuperIF_Stub.java:60)
[java] at supercomputer.SuperClient.main(Unknown Source)
I dont know if it deploys why it gives error on client side.
Please tell how to use user-defined packages and class in jax-rpc service code ,i am not talking about passing user-defined parameters i am just talking about making objects of user defined classes in jax-rpc service.I think there is some problem in classpath.
Please guide me in doing that.
Thanks,
Farrukh

Farrukh,
I don't know if your error is about a missing class from your custom package, ... what track did you followed to say that?
To use your package in the implementation of you web service, you should only follow the rules of making a web application: put your package jar in your \lib directory inside WEB-INF/ or your package classes unjared in classes (also in WEB-INF/).
As I already said, I have doubts that your error should be originated from a missing class from your package, but:
-try to see the logs (errors?) when you deploy your web service that could give a hint about the problem.
-try to see if you can access your endpoint through your browser to see if there is a online status
-display your config/WSDL file, and the steps you did to build your web service.
regards,
Pedro Salazar.

Thanks Lawrence but the point is, I already own the $600 dollar device (given as a gift) and secondly because to purchase a web cam that has the same quality as the iPhone is actually just a bit more than $10 and I'm not really desirous to spend anymore money based on my budget. Any ideas of whether or not it can actually be done via USB OR do you have experience with an actual App that works via wireless to a PC? Thanks again...

How to use HTML or XML described visual forms for data entry in Java app?

Hi,
We are considering to use HTML as a mean of configuration for visual content and layout of data entry dialogs in our Java GUI applications. Java program will need to be able to populate/collect data into/from dialog controls. I am guessing that JEditorPane and FormView classes could be used for this but I have not figured out yet how to do this.
I would really appreciate any help you could provide with respect to this. Please share any tips, utilities, references, etc. Maybe one can suggest non-HTML (e.g. XML, UIML, ...) way to achieve the same requirements and recommend some utilities respectively.
Thanks.
-Vitaly

Just to clarify, we need a solution for Java application (no applet, no web server, no servlets, no JSPs, no EJBs).
