Proxy authentication for existing Java application

Hi all,
I'm trying to run Protege - http://protege.stanford.edu - and it needs to fetch some files from the net, so I have to make it pass my company's proxy, which requires authentication.
I tried to add the following options in the .lax file, but got a 407 / proxy auth error
lax.nl.java.option.additional=-Dhttp.proxySet=true
-Dhttp.proxyHost=YOUR_PROXY_HOST -Dhttp.proxyPort=YOUR_PROXY_PORT
-Dhttp.proxyUser=YOUR_PROXY_USER -Dhttp.proxyPassword=YOUR_PROXY_PASSWOR
The only way I found to make an application accept proxy auth is http://www.javaworld.com/javaworld/javatips/jw-javatip42.html but I'll need to hack my application source code, recompile ...
Is there a way to pass such proxy auth parameters to an existing app without changing any line in its source code ? Or a way to create a wrapper around it that will catch HTTP connections to add proxy parameters to it ?
Thanks a lot for any hint !

-Dhttp.proxyUser=YOUR_PROXY_USER
-Dhttp.proxyPassword=YOUR_PROXY_PASSWORAs far as I can tell these two settings seem to be urban myth, or specific to some non-Sun vendor or external package. They do nothing in the JDK.

Use Sun Java Studio 2 with Existing Java Application

I have started using Sun Java Studio 2 and having fun and little difficulty creating a new Java web application from scatch. My question is where do I find information on Java Studio configuration to allow Java Studio to load up and modify Java server pages/forms in an existing Java application that I did not write?
The Java application has been created with Javabeans and using BEA Weblogic version 7, with a SQL-Server 2000 database backend.
Below is a bit of code out of one of the main Java forms.
<%@ page buffer="256kb" autoFlush="false" errorPage="../../common/system/error.jsp"
import="psdi.jsp.beans.*, psdi.jsp.common.*, psdi.jsp.app.wotrack.*, psdi.jsp.util.* , psdi.mbo.* , psdi.util.* "%>
I have looked around and have not found what I need to setup in Java Studio to allow me to load up a form and view it in the Visual designer, I keep getting errors on the psdi. references and cannot load up any pages.
I see on the server install ia folder under the main root <DIR> called <apps>, and inside the <apps> folder is a folder called <jsp> and in the <jsp> folder are sub folders for each main module within the application with all the related .jsp files. I have been manually editing the .jsp files using Windows Notpad and saving the changes. Then I rebuild the .ear file and my changes work fine. Since I have a lot of changes to make there has to be a better way than using Notpad.
My hope is somewhere is a point-by-point document on what to so I can use Sun Java Studio 2 to make my changes in a visual IDE.
Any assistance would really be appreciated.

Hi Giri,
Yep, this I know,b ut when I do I get errors messages and am looking for some form of point-bypoint instuction that better explains how to setup up custom libraries in Sun Java Studio, custom tags, etc.

How to create a .exe file for a java application

Hi, I want to create a .exe file for a java application I am developing so that I can schedule it to run at a particular time using Windows Scheduler on WinNT. Is there any way to accomplish this? Or is there any other way in which a Java application can be scheduled to run at a particular time on Windows everyday?

Create a .bat file and run that. Just have, in the .bat file:
java YourClassName Alternatively, you can use javaw YourClassName (without *.bat, just put it into Windows Scheduler like suggested above).
using javaw won't pop up any window...

Update JVM for Sun Java Application Server8

Hi:
I am wondering how do I update the JVM for an already installed Sun Java application Server 8. Does any one know how to do this? Thanks

Hi Experts,
Need some good links and documentataion for "Sun Java Application Server". When I am making a serch for this I am getting links to Glassfish.
So please help on the documentation for Sun Java Application Server .
Regards.This is because Glassfish is the same product as Sun Java Application Server in that regard.
The versioning goes as follows:
Kiva Enterprise Server 1.x
Kiva Application Server 2.x
Netscape Application Server 4.x
NetDynamics 5.x
SunOne/iPlanet Application Server 6.x (merger of NAS4 and ND5)
Sun Java Application Server 7.x = SunONE/iPlanet Application Server 7.x
Sun Java Application Server 8.x = Java Enterprise Server Application Server 8.x
Sun Java Application Server 9.x ~= Glassfish 2.x
Glassfish 3.x
Clear now? :)

ASA - cut through proxy authentication for RDP?

I know how to set this up on a router (dynamic access-list - lock and key)... But, I'm having trouble understanding how to setup OUTSIDE to INSIDE cut through proxy authentication for RDP.
OUTSIDE to INSIDE RDP is currently working.
I have 2 servers I want RDP open for..
[*]OUTSIDE 1.1.1.1 to INSIDE 10.10.70.100
[*]OUTSIDE 1.1.1.2 to INSIDE 10.10.50.200
What's required for OUTSIDE users to authenticate on the ASA before allowing port 3389 opens? I was hoping for is a way to SSH into this ASA, login with a special user, then have the ASA add a dynamic ACE on the OUTSISE interface to open 3389 for a designated time limit. Is this possible?
Here is my current config.

You're running ASA 8.2(5). In 8.4(2) Cisco added support for what they call Identity Firewall rules. That is, you can make access-lists entries specific to users (or object groups containing users).
There's an overview document on this posted here. It's a bit dated but I believe the only change is that Cisco is now preferring use of the more current Context Directory Agent (CDA) - a free VM they provide - vs. the deprecated AD agent (software service that runs on your DC).

SWC and Unit for PI 7.0 for a Java application

i want to integrate my Java application with XI.
In SLD what should i mention the SWC and Unit for PI 7.0 for a Java application to be integrated????

If your Java application is not provided by SAP, you create a new product and software component for this in SLD.

Http proxy authentication for JDev 10.1.3

Hi,
I found the http proxy settings in the "tools->preferences->Web Browser and Proxy" but there are no settings for the username and password. Is there some other way that I can add these.
The problem is that whenver JDeveloper wants to do some http stuff it (or something else is doing it) asks me for the proxy user name & password - this happens over and over again. If JDev is doing this then surely it should remember the username & password.
I sometimes get a JDeveloper dialog "waiting for the connection" come up over the proxy auth dialog and I have to cancel the function so I can authenticate, then re-request the function.
I wish I didn't have the proxy authentication but I have no choice in this dev environment. I do get to choose JDeveloper at least.
Regards,
Simon.

Hi,
I get it when I 'check for updates' and I get it again when I 'go to JavaDoc' - and this is the one where the "waiting for connection dialog" pops on top of the proxy log in and I have to cancel it to log in. Then all subsequent 'go to JavaDoc' requests go straight through.
I would prefer it if I could just configure (in proxy preferences) the username and password so it never asks me. I dont care if it less secure storing the password since I think authenticating proxies are a dumb idea anyway. If the password is not supplied then JDev can ask for it like it does now to keep the security-paranoid people happy.
Also, this morning I got this Exception which appeared at the same time I got a proxy auth window. When JDev finally started all my previously open windows were lost. No real problem but unexpected. Here is the stack dump:

How do I set proxy settings for a Java app behind a corporate server?

I have the source code of a Download Manager program written in Java. It has to be run within my college network in which we use the "Corporate Client" server to access the internet. The HTTP proxy is 172.16.68.6 and Port number is 3128. How do I define these parameters in my java program so that it can download files from the internet?
The source code for the program is:
There are four classes:
1. DownloadManager.java
2. Download.java
3. DownloadTable.java
4. ProgressRenderer.java

Thank you for the quick reply! But the solution provided by you, it seems, has still not been able to address my issue. I ran the program at command prompt with your said parameters, but the download still gave an error in the App window.
Also, is there some way of defining these parameters in the source code? I am keen in using NetBeans to run the program.
Cheers!

Proxy support for third party applications

Hi all.
I have seen many posts by users saying that some applications cannot access the internet, while connected to a network with proxy authentication.
Ultimately, the problem lies in iOS not supporting system-wide proxy settings. We are therefore stuck with applications where the developer has not included their own proxy authentication methods. This is really pathetic in my opinion, seeing as the iPad, although primarily focused on a media and leisure based market, is actually used by a lot of people in the enterprise world.
There has not been any official announcement by Apple about this issue on other threads, or any announcement as to when support for this will be added. As a university student, I am forced to bring both my MacBook and iPad to campus, simply because I cannot access certain online services, such as DropBox, from my iPad. It actually makes me question what the point in getting the device was in the first place, as my primary intended usage is to eliminate the need for my MacBook to come with me to university.
I would like Apple to please give any response on this, especially seeing as these devices are bought by many people with the intention of using it on many different networks on the move. Please, don't get me wrong - with the applications that work, and the usage I have with my iPad as is, I really enjoy the device, and it is great in many aspects, but simple functions such as internet access for applications under proxy authentication should be a given feature.
With that all said, I have not had a chance to update to 4.3.1 yet, and I am not aware if it has been fixed yet or not - the change log says nothing about it though. Has anyone found a solution to this yet? Are some of you also experiencing it?
MrP.
EDIT: I notice that in the change log of 4.3.1, it says: "Resolves an issue authenticating with some enterprise web services". Can anyone confirm if this has fixed the issue?

Yes same here, Ipad and Iphone 4S all iOS 5.1.1 behind a proxy....Safari works but pretty much none of my other Apps. proxy acceptance will be a critical blow in the war for the Enterprise market. I need access to Apps I now rely on and they simply do not work.
With MS Surface only weeks away once people start using this with 100% success through a proxy, ( not to mention real Office that works with macros and all formatting..Oh and stylus friendly too!) a lot of apple devices may start to gather dust.
Common Apple, lets move on from Toys and get serious about work too. I am guessing there are a lot of us out there trying to make ipads work at work...help us out!

Simple Web Frontend for existing Java app

Hi there!
(sorry for my english at first ;)
I have an existing java app which currently is used via command line. It's a server application which mostly does monitoring outputs and functions you can use in the shell are like starting/stopping the server. For these outputs and for starting/stopping and so on i want to create a simple web frontend which gives me the ability to do this.
What do i need? It would be fine if i do not have to set up a large tomcat server because the program should run out of the box. Of course i want to access the website via the internet (simple login). The whole thing would be about 2-5 simple pages. Best thing would be if i could update the monitoring variables via java script.
Can i use servlets (not much experience with it so far, that's why i ask :) )? What do i need for the webserver? Can i access my data variables from right from the servlet?
Thanks in advance,
kiwaque

If you are familiar with Swing, I would suggest GWT for the Frontend... you can build and debug the Frontend similar to a Swing App, and then compile it to HTML/CSS/Javascript...

Creating Packages and Namespace for Webdynpro Java applications in NWDS

Hi Experts,
I am working on a stand alone application and using NWDS for the same. This application consist of some Webdynpro Java apps, Dictionary perspective DC's and BPM applications.
I need to create a package and name space for all the applications. I have read some documents on creating SC in SLD and using it in NWDI. But since I am working on NWDS i am not able to see the SC.
May be I am not following a correct procedure. Can some one provide a basic document or can tell me steps in short that i need to follow, for Name space and package creation and how to use them in NWDS.
I am working on CE7.1 ehp1.
Regards
Pranav

Mechanism for monitor java application or JVM

Ladies & Gentleman,
I develop Java application under Windows 2000 datacenter. For gurantee to capture all of abnormal situation of java application and also JVM, I need to know how to capture the situation. Do any other tools to do these things? I am very appreciated if you could tell me.

You don't exactly need any specific tools to just capture exceptions, that can easily be done by wrapping the program you want to monitor with your own main() method and adding some shutdown hooks...
But it would be nice to know what you want to do once it happens....
Regardless of which, here's an example of that wrap...
import java.lang.reflect.*;
public class Watch extends Thread
     public void run()
          System.out.println("VM is closing down");
     public static void main(String[] args) throws Exception
          if (args.length == 0)
               System.out.println("You must supply the name of the class to start with.");
               System.exit(1);
          Runtime.getRuntime().addShutdownHook(new Watch());
          try
               Class theClass = Class.forName(args[0]);
               Method theMethod = theClass.getDeclaredMethod("main", new Class[]{String[].class});
               String[] theNewArray = new String[args.length - 1];
               System.arraycopy(args, 1, theNewArray, 0, theNewArray.length);
               System.out.println("Starting program with class "+args[0]+"...");
               theMethod.invoke(null, new Object[]{theNewArray});
               System.out.println("Program is done running.");
          catch (ClassNotFoundException cnfe)
               System.out.println("No such class: '"+args[0]+"'");
          catch (NoSuchMethodException nsme)
               System.out.println("The class "+args[0]+" has no main method.");
          catch (SecurityException se)
               System.out.println("Can't start: "+se.getMessage());
          catch (IllegalAccessException iae)
               System.out.println("Can't invoke main method in class "+args[0]+": "+iae.getMessage());
          catch (Exception ite)
               System.out.println("Exception occurred when running class "+args[0]+": "+ite.getMessage());
}You can easily just swap those System.out's for something else.
However, if you mean watching the process from outside the VM, then you need something else, I suppose.

Specifying a process name for a java application

Hi,
we run multiple java applications on our Windows 2003 server. It is diffucult to monitor these processes as they all appear as "java.exe" in the Windows Task Manager > Processes.
Is there a way to specify a name for such a process? My colleague has suggested creating a copy of java.exe for each process, and then renaming the executable to reflect the name of the application it is starting. I think this method is not very flexible.
Thank you for your suggestions in advance.

If you don't like it then I think (as a guess only) that the following is possible.
1. Create your own java launcher. As long as you don't distribute it you can start with the java source code for this.
2. Find the Windows API that allows you to change the application name on start up.
3. Modify the launcher to do this via a command line option.
Of course there might not be any such API.
