Interface in jsp

why we can not implement an interface in jsp

Because you shouldn't ? A jsp should have nothing else to do then generate a response, interfaces should be implemented by action classes, data access objects, beans, etc.

Import interfaces in jsp

Hi, all.
I'm new with EJB and try to test something in order to get to know EJB.
I just faced with some problem. I am trying to solve this for couple hours now..
Here is the problem.
I get this error when I compile jsp file.
C:\Documents and Settings\Administrator\TestEApps\TestEApps-war\build\generated\src\org\apache\jsp\actionForm_jsp.java:8: '.' expected

What's wrong with this?
Thank you.

Hmm try doing your context like this....
InitialContext ctx = new InitialContext();
HelloEJBRemoteHome home = (HelloEJBRemoteHome ) PortableRemoteObject.narrow(ctx.lookup("ejb/HelloApp/HelloEJB"),HelloEJBRemoteHome.class);Note.... A EJB application has these classes..
HelloEJB.java
HelloEJBBean.java
HelloEJBRemote.java
HelloEJBRemoteHome.java
So you have to set up the Context in a way of ejb/HelloApp/HelloEJB
Which ejb is standard, and HelloApp is the application name localhost:8080/HelloApp/ and HelloEJB is the HelloEJB.java class
REmember that HelloEJB.java extends the EJB Object so that the EJB Interface will take care of all the remote...
You have to organize your EJB beans and Home Locals and Remotes... It is a bit complicated telling you what is wrong if we don't know your full structure...
But thats the taste of it

Pass user-defined Interfaces between JSPs

          Hi, I am using weblogic 6.0wSP1 on win2k. I'd like to pass some
          user_defined interfaces/classes variables between JSPs at run time. I've been
          tried using <jsp:include page...> However, the issue is that it was using http

          using getParameterValues("name"). So does anyone know how I can handle it?
          Any help is appreciated...

JSP back-end interface to Remote server. Please help the newbie

Could someone comment on pros and cons of the JSP back-end interfaces to the remote server/programs using..
(1) Socket Interface between JSP and Remote Server. One socket for one JSP session. JSP to create and delete the socket when done.
(2) RMI between JSP and Remote program.
(3) Message Exchange using JMS between JSP and the Remote Server.
(4) Peer-to-peer JAXM message exchange. JSP/JAXM Client to Remote JAXM Server
(5) Anything else?
Thanks in advance..

(1) Socket Interface between JSP and Remote Server.
One socket for one JSP session. JSP to create and
delete the socket when done.JSPs are compiled to servlets, which use the HTTP protocol. The remote server should be the servlet/JSP engine.
(2) RMI between JSP and Remote program.As soon as you say "JSP", you're assuming HTTP request/response. If you want to talk to RMI objects, I think that's best done elsewhere than a JSP. They really should be for interface only. Have your JSP talk to a central, front controller servlet and have it invoke methods that deal with RMI objects or EJBs or POJOs on the back end. That stuff doesn't belong in JSPs, IMO.
(3) Message Exchange using JMS between JSP and the Remote Server.No.
(4) Peer-to-peer JAXM message exchange. JSP/JAXM
Client to Remote JAXM ServerNo. This is crazy. JSP = HTTP, which is client/server by definition.
(5) Anything else?All these might be fine options, but they don't belong in JSPs. Those should be for Web interface, a thin client. The details of how you process (e.g., RMI vs. EJB, synchronous vs. asynchronous, etc.) are best encapsulated somewhere else besides a JSP.
HTTP is a client/server, synchronous, request/response protocol, of course. As soon as you say JSP, these assumptions are built into your system. You can do asynchronous processing, but you still have to send back a response synchronously (e.g., "Your order is being processed. Please come back.")

JNDI Lookup in JSP fails for EJB 3.0

I am new to Java technology. I read the EJB FAQ, NetBeans docs and may forum discussions and I am still confused with the error I am having.
Background:
I have developed a persistance bean and related sessions beans (similar to the customer-cmp-ear application in the Java App Server samples). Now I am trying to access this bean using a JSP. After deploying the war file in the App Server and try to access the page, I get the following error.
javax.naming.NameNotFoundException: No object bound to name java:comp/env/ConsumerSessionLocal
After reading many articles, I understood that I dont have to prepare any descriptors, or JAR files for EJB 3.0.
Environment Details:
Java App Server Ver 9.0
NetBeans 5.5
I normally build the war files using NetBeans.
I use App Server Admin console to deploy the web applications using the above war file.
EJB details:
Persistance EJB : person.java
Session Objects
Consumer.java (this implements ConsumerSessionLocal, ConsumerSessionRemote). This Stateless bean accesses the methods in person.java.
ConsumerSessionLocal.java - local interface
ConsumerSessionRemote.java - remote interface
SearchConsumer.jsp
This JSP page is calling the ConsumerSessionLocal using the JNDI lookup through InitialContext.
Here is the Code snippet:
try {
InitialContext ic = new InitialContext();
Object o = ic.lookup("java:comp/env/ConsumerSessionLocal");
ConsumerSessionLocal consSession = (ConsumerSessionLocal) o;
I am able to see the jsp page in the browser, however, after a submit action, I get the Java Naming Exception error.
javax.naming.NameNotFoundException: No object bound for java:comp/env/ConsumerSessionLocal
I would appreciate your help/any of your thoughts.
Thanks in advance.
-Ram

I did not really solve it. Instead I used some of the tutorials that used JNDI lookup and modified those as my way forward. I did not really find out exactly what I was doing wrong.

Hello everyone,I need to build a Java interface for JSP to interact with crystal reports.Could anyone recommend any book or forward me the url's where I can find the related material with examples. Eagerly Waiting for reply!Thanks,Prathima.

The latest version of the Java Report Component (JRC) is available from the Diamond website. This download is actually a plugin for Eclipse but you can still use the JRC runtime jars to use the SDK APIs in your JSP page. You will also find lots of resources such as samples, videos, and forums to help you get started. You can also refer to the DevLibrary for more information.

can anyone tell me why??
Thank you.

Oracle iFS 1.0 and 1.1 do not support modifying the out-of-the-box Web UI.
With these releases, you can build a full Web user interface using JSPs, or plug in a JSP for rendering specific types of documents (by Content Type).
Please refer to the Oracle iFS Developer's Guide for instructions on building custom Web user interfaces.

JSP as UI technology with GP instead of Webdynpro

Instead of Webdynpro, I want to use JSP as UI technology to deliver screens to the GP process layer.
How can I work with the GP interface from JSP when the GP interface is only available from Webdynpro?
I wish GP Development would deliver such callable object "JSP with GP Interface" or at least provide means/apis for me to create it.
Or maybe someone came up with a creative way to manage it and would love to hear from you.

Hi,
I looked at the demo
http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/ADF112/ADF112.html
It's interesting.
However, I would point out two things:
1- Before Oracle, Sun failed with UI technologies: there was AWT then Swing then Java FX. None of them was a star. The only place where Sun really won the UI war is the Bluray Disc format.
2- About half of the RIA in the financial/banking industry are developed with Flex, the other half is developed with Silverlight / WPF. HTML 5 is being taken up by some, but you still end up with the usual problem of having to pick up an AJAX framework, and get tied to a vendor anyway in the end. Never heard about any project developed with Oracle ADF yet.

Not resolving Local Interface

C running under Java?

Greetings,
I have the need to create a Java program using SWING or using a web interface with JSP/Servlets however one of the program modules requires the input of a C code that needs to be run.
Is this possible?
For example, In the module I have a TextArea where I input something like
#include <stdio.h>
printf("Hello");
(I'm not a C programmer just say this as reference)
And Java will compile it in C and execute it.
Is this possible in both enviroments? Application AND/OR WEB using JSP/Servlets?
Thank you.

Simple.
java.lang.Runtime.exec() returns a java.lang.Process object.
With this object you can get an inputstream returned from [url http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Process.html#getInputStream()]Process.getInputStream() call that will allow you to read all data outputed from the process.
With that data rread, you can then output it in a Frame or a HTML page or whatever.

How do I access files within projects of the same web application?

Using JDeveloper Studio 11.1.1.1.0
I'm creating a web application using the Model-View-Controller design pattern. Model represents data, View represents data display, and Controller is control...
In my application, I created two projects: EJBModel and UserInterface. EJBModel contains the model aspect so it has entity objects and beans to access/manipulate the data. The UserInterface project stores the web interface - mostly jsps. In the UserInterface project, I need a managed bean that calls methods from the beans created in the EJBModel project. I can do this using the @EJB annotation and creating an instance of the class, but since the files are in separate projects that can't see each other and JDeveloper shows an error because it can't find the necessary file. It is best practice to create two projects as it keeps both elements distinct.
So I wanted to know the best way to access the files stored in separate projects within the same application. Is there a way to package them together?
Thanks...

In the UI project, go to project properties->dependencies and add a dependency on the model project.
This way JDeveloper will know what classes you are referencing.
