RMI and JSP

hallo,
I am beginner in java, and I had created an RMI application that offer echo service and it works properly, but, what do I need to create a JSP page to benefit from this service, I tried to put in this page th same as in the client in my RMI application, but there was an error as foolow:
16.05.2007 15:33:50 org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket
WARNUNG: Endpoint ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8080] security exception: java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:2441 accept,resolve)
thank you.

don't use scriptlets...
But that's not why this fails. Looks like you have a configuration problem on your server.

A problem in RMI with JSP..pls help

RMI with Java is working fine,but...
1. I am facing a problem when i use RMI with JSP..its throwing an exception during "Naming.lookup"..here is my code snippet:
// i have stored the ServerInf and other classes in a package and i have imported it in the jsp code....object ref is getting created but lookup is throwing an exception...thoguh RMI registry is working(started)
<%
try {
ServerInf ref = (ServerInf)Naming.lookup("rmi://localhost:1098/Server_bind");
catch (Exception ex) {
ex.printStackTrace();
%>
Pls tel me the cause.
2. If i try to use RMI with Servlet and JSP, then wen the JSP runs then, it simply calls the servlet file and displayes a lonk to it instead of executing the servlet class. pls help me with this too...below is the invoking statement:

Rmi and jms

It is the fouth thread for the jms and rmi. Is there anyone that can answer me?
I can run rmi and jms sample in the oc4j standalone. but if I run in the application server, there are always some errrors. I have searched all the forum and the documents about application. I found nothing helping to me.
Is there a tutoral for run rmi and jms in the application server step by step?
Was there anyone help me, I will lose my job soon.
God save me.

I installed the oracle9ias9.02 on linux 7.1. and the installation is ok. I can deploy application.
I deploy the ear file and the jsp and servlet are running ok.
In the application, there is a applet which will call the method through rmi.
and the bean which provide the rmi method will recieve jms messages in the server side.
here is the applet:

all these bean will run ok in the sun j2ee envrionment, but can not work in the application server.
in the sun j2ee, I will run rmiregister and the run the rmi server, the applet then can invoke the rmi method.
in the oracle9ias application server, how i can run the rmi server
thanks

Help Please!!!!! RMI and Threads

My server has 10 threads doing constant polling of network equipment through use of SNMP. I have a servlet that connects to my server and retrieves collected information by using RMI and displays it in the browser window. Browser refreshes the information very often. So, there is a constant flow of RMI traffic between the server and the servlet.
Here is the problem:
There are times when my server stops responding to RMI requests issued by the servlet. All 10 threads that are doing SNMP polling stop being scheduled by the JVM. They block! This picular situation occurs with the server only during RMI requests coming from servlet. It doesn't always happen though. Also, I've noticed that if RMI load is high this problem emerges again.
I get no RMI exceptions.
I am using Apache and Jserv.
All of my attempts to understand and fix the problem have been futile so far. Could a heavy RMI load between my server and servlet be causing my threads to block? Should I decrease my RMI traffic?

You have the same problem I had. You need to set the timeout .. so once the timeout is exceeded, an exception is thrown. You need to create a custom RMISocketFactory ... trust me, its easier than it sounds ..check the answers to my post at:
http://forums.java.sun.com/thread.jsp?forum=58&thread=167287
hope that helps.

What is the difference between RMI and JAX-RPC?

Dear All
First of all my understanding of RMI and JAX-RPC:
RMI is JAVA only version of RPC. It can't talk to any other language.
JAX-RPC is a part of JWSDP and if you implement your client and server with JAX-RPC, client written in any language can talk with JAX-RPC implementation.
What else makes them different and am I right with my understanding?
Finally, I would like to develop clients which will have a java class, say httpserver.java, which will act like a http server, listens to a http port. Now, Two such client will run in two different PC and I want to call a module from one client to another which should be accessible via my httpserver.java. For that which should be my choice RMI or JAX-RPC? Can I achive it with http get-post method, as I am expecting to read some value of variables from one client to the another.
Say class A has variable a, aa, aaa and clas B has variable b, bb, bbb. Now I want to read the value of b, bb, bbb from class A. How do I do that when class B is listening to a http port with my httpserver.java class.
Lastly, say B is listening to a http port and I want to send a file to B from A. How can I do that? Remember, B didn�t ask for that. How can A send a file to B when B is listening to a http port with my httpserver.java.

simply put, RMI allows you to (semi) transparently treat remote objects as if they were local, and your distributed application can be written (more or less) like a "normal" java app. Sockets just give you a "raw" connection to work with, and you get to build up your application from that.
I hope that helped

Please help: RMI and Swing/AWT issue

Hi guys, I've been having a lot of trouble trying to get a GUI application to work with RMI. I'd appreciate any help. Here's the story:
I wrote a Java application and its GUI using Netbeans. In a nutshell, the application is about performing searches. I am now at the point where I need exterior programs to use my application's search capabilities, thus needing RMI. Such exterior programs are to call methods currently implemented in my application.
I implemented RMI, and got the client --> server communication working. However, the GUI just breaks. It starts outputting exceptions, gets delayed, doesn't update properly, some parts of it stop working.... basically hysterical behavior.
Now take a look at this line within my server class:
Naming.rebind("SearchProgram", mySearchProgram);
If I take it out, RMI obviously does not work... but the application and its GUI work flawlessly. If I put it in, the RMI calls work, but the GUI's above symptoms occur again. Among the symptoms are null pointer exceptions which all look similar, are related to "AWT-EventQueue-0", and keep ocurring. Here's just snippet of the errors outputted:

There are no complaints about anything within my code, it's all GUI related whenever I make a bind() or rebind() call.
Again, any help here would be great... cause this one's just beating me.
Thanks!

Maybe you want to change that worker thread to
not do RMI but anything else (dummy data) to see if it really is RMI, I doubt it, I think you are updating some structures that have to do with swing GUI and hence you will hang.
Just check this out.

Ideas pls for a small application on java and jsp?

hi ,
I would like to create an application which for resume. I would like to codify the java code . The java code should be able to autogenerate jsp file's since the output of the resume would be on an jsp page. To add it simply a wizard for dynamic resume creation using java swings and jsp. Code for jsp should be autogenerated please note it.
Ideas please!
Thanks in advance

I'd like to add more information to Patreck's suggestion.
JSP pages are wonderful if you need the web server to perform some actions before sending you the final web page.
Here, you don't need the web server to do anything because your Swing application can do it for you. As Patreck implies, Swing can make a connection to the database, retrieve any information you want, perform whatever logic you need, and write the output to an HTML file.
To give you an example, you can use Internet Explorer to view a basic web page on your hard disk. You can also use Microsoft Word to view the same basic web page. They both do the same task and there is no need to force IE to use its Word plug-in in order to view the web page.
JSPs are not necessary because Swing will do all of the work for you. You only need JSPs if you want people to use your program through a web browser because they can't do Swing inside a web browser. You should only use one or the other, not both. Understand now?
If you really really must generate JSP code from a Swing application, then just write out the JSP stuff in the file. For example...
public void createWebPage( Printwriter pw, String myName ) {
   pw.println( "<% String myJSPName = \"" + myName + "\" %>" );
   pw.println( "<HTML>");
   pw.println( "<HEAD>");
   pw.println( "<TITLE>My Resume</TITLE>" );
   pw.println( "</HEAD>");
   pw.println( "<BODY>" );
   pw.println( "<H1>My name is " + myName + " and my JSP name is <%= myJSPName %></H1>" );
   pw.println( "</BODY>" );
   pw.println( "</HTML>" );
}As you can see, it's pointless to embed JSP when you can do all the programming within Swing first and just write out the correct response.

Connection to CRX via RMI and getting WeakReference value..... with an exception!

Hi there,
I have the following problem.
I opened a ticket in Day Care Support system, about CRX users/group membership that got lost while synchronization with our LDAP server.
Although when the user and the group had been created (and therefore taken from that same LDAP server), the membership was good.... but after some time the membership got lost......
So what i am trying to do now is a Java program that connects to CRX via RMI.
And gets the list of all the users from a group (aka membership).
The idea is to monitor the membership each seconds.
But when trying to get the property "rep:members" of the group, I have the following exception :
javax.jcr.ValueFormatException: Unknown value type 10
          at org.apache.jackrabbit.rmi.server.ServerObject.getRepositoryException(ServerObject.java:13 9)
          at org.apache.jackrabbit.rmi.server.ServerProperty.getValues(ServerProperty.java:71)

          at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:322)"
I searched a little bit and found that "10" is the number for type WeakReference.
That's normal to me because memberships are stored in the group as a list reference to users linked to that group....
Anyways, what's not normal to me is that when the type is "10" the API does not let me get the Value (cf. ServerProperty.getValues() method)

Cannot checkin/checkout html, js, txt, and jsp files in MS Sharepoint Workspace 2010

I am having issues checkin/checkout html, js and jsp files in Microsoft Sharepoint Workspace 2010. I can access (checkin/checkout) any files in the actual Sharepoint site, but when I am synchronized to the site in Sharepoint Workspace 2010 I cannot access
html, js, and jsp files. When I try to checkout a html file, a message pops up saying:
"Can not perform this operation. This document has been checked out or may no longer exist."
Could this be a synchronization issue, or was Sharepoint Workspace 2010 not design to work with html, js, txt, and jsp files?

Hi Armando,
I'm afraid that you posted your question on the wrong forum. This forum is intended for Project Server questions. Please go to this forum in order to have answers from experts:

Creating FOrums with Servlet and JSP

Hi everyone,
Is there a good resource that explains how to build a forum using servlets and JSP technology?
Regards,
Basil Mahdi

please let me know here if you find any useful resources...I am in the process of writing my own searchable threaded forum for my company with JSP's/servlets. It's a very slow process at the moment though...if I ever finish it, I'll gladly share it.

RMI and Swing Events

Hi,
I have a problem, integrating an application with RMI and a Client side with swing.
I have un RMI object that does something, and in any time I want to inform to the client side rmi... I did something like:
// This is the REmote implementation
public MyRemoteImpl extends Activatable implements MyRemote{
EventListenerList listeners;
// code for activation, etc.......
public void addListener(MyListener l){
    // add the listener in the list...
public void fireEvent(String msgEvent){
    // in each listener that is MyListener, .doEvent(String msg)
// Methods that calls fireEvent...
// Mylistener interface..
public MyListener implements EventListener{
public void doEvent(String msg);
// The swing client side.
public MyClient extends JPanel implements MyListener{
MyRemote rem=null;
// In the start of ui.. Ido:
rem.addListener(this);
public void doEvent(String msg){
    // Puts the message at one component....
}The problem is that when the doEvent of the Swing side is called, it is executing in the rmid... And the UI is not updated...
What I do wrong??
Thanks and Best Regards.

I wrote an application that does something similar, it receives some event and modifies a JTree accordingly. You should try using the java.awt.EventQueue.invokeLater(Runnable) method. Something like this:
public void doEvent(String msg) {
    // Determine what changes need to be made
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            // Only the GUI component modification calls need to go here
}

How to master good design with EJB and JSP?

I use JSP to calling EJB. But the .jsp file is complex and it's difficult to maintain...I just want to work higher efficent with EJB,JSP and JavaBean. I want to know is there a good design with EJB and JSP? and is there any good material about MVC for EJB,JSP and JavaBean?

You should read the J2EE blueprint available on this website. Better download the PDF, and print it for yourself so you can read it anytime.

WL vs. WL-express and JSP vs. javascript/SQL

folks-
i am trying to convince a certain party to
disband a web-based job tracking system being
written in ASP, javascript, html, css and SQL.
it will be hosted on MS webserver running NT.
i am trying to convince them to use JSP and
WL express. i have done two years of EJB
component work on weblogic, however, i have not
done work with JSP or thin-clients. i was mostly
business-logic.
anyway i have some questions and need some
direction. i already know JSP is better than
ASP/javascript etc. because:
* ASP is proprietary. ditto for VBscript
* with an IDE creating JSP is easy and JSP
automatically creates servlets which is way
faster than by hand
* JSP is JAVA based and hence benefits from
all the portability pluses of JAVA
but here are the more difficult questions:
* why is WL express better than an MS
web server? (not including WL market share
and size. after all MS can claim that)
* since WL express does not have an EJB
container, how do you access the database?
via JDBC? does one just have JDBC code
floating around?
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
* if a web app grows beyond JSP with WL express
into the need for an EJB container, i would
think that most of the app needs to re-written
as business-logic must be refactored into EJBs
and all JDBC code will be replaced by container
managed beans. this sounds a like a lot of
rework.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and
force across the network?
with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?

* since WL express does not have an EJB
container, how do you access the database?

Use JDO or an OR-mapper or embed JDBC into your own data access classes.
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
Presentation=JSP
Logic=Servlet
Data access=JDO or similar

think that most of the app needs to re-written

You should be able to tell up front if it a tx-intensive app that requires
WLS.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and
force across the network?
They aren't exclusive. For dynamic pages, use Javascript on the front end,
JSP on the back.
* with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?
In the real world, and for most apps, while Java has the architectural edge,
they both have similar scalability and similar robustness. MS gives you no
choice though, and you rewrite every time they see a new buzzword. You can't
leave MS-land without abandoning almost everything. You can leave WLS in a
week if you have to.
It's an investment. Invest wisely.

Hot swap and JSP debugging for Weblogic in exploded format?

Hi,
I'm trying to use JDeveloper for JSF development to be deployed to a weblogic server.
I must say JDeveloper is a great tool for JSF development as none of the free IDE in the market can do what JDeveloper does.
However, I have a question on hot swap and JSP debugging.
I have managed to setup JDeveloper to debug my JSF application deploy to my Weblogic server's applications folder in exploded format.
I can step through the java code.
However, I didn't manage to do a hot swap and the break point set in the JSF-JSP does not seems to take effect.
I would appreciate any advice on the problem.
Thanks.
Han Ming

How did you setup the server to handle exploded format? Appreciate the help. Sorry can't help with your question though.
Thnx.
