How expensive is Java GUI

Developers,
A small question - Assume i have 6 JComponents of some sort arranged in a JFrame. Based on a Socket thread which is running continuosly in the background and executing a SQL statement the Components would need to be repainted().
Each component does some slightly complex calculations - say calculating average of 1000 numbers as an example -
Realistically can this be done - ie will the performance be reasonable enough - Where do you think the bottleneck will be - In the Socket SQL query or in repaiting.
Many Thanks

What I suggest Just find out whether there is any push Solution you can provide
As i feel If you use Push based solution I mean query database again and again Just tell the Database/Server to give you the updated data when changed

How to run java GUI application on embedded ARM linux board

Hi friends,
This is suresh. I am Embedded developer .Right now i am using Embedded linux board biased by TI OMAP IC (arm7) .This is working fine.Actually we created one jar application .It is working good in GPOS.But when i was running that jar file in my embedded board. i got some errors. Last two weeks i was searching on the net.But still didn't get proper output.Right now i having "java 1.7.0_60" with headful support package for arm7. Here i have attached my error screen shot.Thanks

Using the package manger in your Linux distribution, try installing libX11 package. We had a similar issue using Java SE 8 embedded on arch Linux as with some distros you are starting from the bare basics and need to add in missing dependencies.

How can I run C programs under a Java GUI?

Hi
I'm looking for some info on how to run a command line program written in another language behind a Java GUI, any advice greatly appreciated, particularly in how to transfer data between the two.
Thanks

Runtime.getRuntime().exec(...)
Transfering info is more complicated. Maybe write and read status from disk?

HOW TO: Create a GUI "Hello World"


This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.
</li>
[*]In your panel, click and drag the cursor to outline the text field.
Don't worry if the text field doesn't have exactly the right size or position.
We will adjust these later.
The Property Inspector now displays attributes of the JTextField.
</li>
[*]In the Property Inspector, change the name (just as you did for the
JPanel) to <TT>displayField</tt>.
</li>
[*]Change the text to nothing (erase the value that is already there).
</li>
[*]In the Component Palette, select the <TT>JButton</tt> component, which looks
like a button being clicked.
</li>
[*]In your panel, click and drag the cursor to outline the button.
The Property Inspector now displays attributes of the JButton.
</li>
[*]In the Property Inspector, change the name and action command
to helloButton.
</li>
[*]Change the text to <TT>Say Hello!</tt>.
</li>
[*]Choose File | Save All.</li>
</ol>
Wiring Up the UI
In this section, we wire the UI so that clicking the button causes "Hello
World!" to display in the text field.
<ol>
[*]In the Property Inspector, select the Events tab.
</li>
[*]Click the box next to the Action Performed field and press the Enter
key.
This creates a method, <TT>helloButton_actionPerformed()</tt>, which will
be invoked when the button is clicked, and displays the source code for the
method stub in the viewer.
</li>
[*]In the viewer, add the following command to the body of the method:
<TT>displayField.setText("Hello World!");</tt>
</li>
[*]Choose File | Save All.</li>
</ol>
Testing the Prototype Application
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field.
</li>
[*]Close your application.</li>
</ol>
Refining the UI
In this section, we polish the UI so that the components have the right size
and alignment, the text in the text field shows up red, and the panel uses the
portable GridBag layout instead of the JDeveloper-specific XYLayout.
<ol>
[*]In the viewer, select the Design tab.
</li>
[*]Select your text field.
</li>
[*]Drag the edges of your text field until it is the size you want.
</li>
[*]Drag the center of the text field until it is the vertical position you
want.
</li>
[*]Right-click the text field and choose Align Center.
This centers your text field horizontally in the frame.
</li>
[*]In the property inspector, click the box next to the foreground field.
</li>
[*]Click the ellipses (...).
A color editor appears.
</li>
[*]Select Red from the dropdown list.
</li>
[*]Click OK.
</li>
[*]On your frame, select your button.
</li>
[*]Drag the right edge of your button until it is the horizontal size you want.
</li>
[*]Select your text field, and multi-select your button by control-clicking
it.
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Same Size Vertical.
This sets the height of all selected components to that of the first selected
component (the text field).
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Align Center.
This aligns the center of all selected components to that of the first selected
component (the text field).
</li>
[*]Select your panel by clicking anywhere on the grey background in the visual
designer.
</li>
[*]In the Property Inspector, click the box beside the layout field.
</li>
[*]Select GridBagLayout from the dropdown list.
</li>
[*]Choose File | Save All.</li>
</ol>
Running the Finished Application From Within JDeveloper
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>
Deploying the Application to Your File System
<ol>
[*] In the Navigator, right-click <tt>HelloGui.jpr</tt> and choose New Deployment
Profile.
The Deployment Profile Wizard opens.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Delivery page, select Web Application or Command-Line Application
from the dropdown list, and click Next.
</li>
[*]On the Staging Area page, in the Deployment Destination field, enter
<tt><JDeveloper>/HelloGui</tt>, where <tt><JDeveloper></tt>
is your JDeveloper root directory. Click Next.
</li>
[*]On the Project page, select all the <tt>.java</tt> files and click Next.
</li>
[*]Skip the Archive page and Applet Tags page by clicking Next on each.
</li>
[*]On the Libraries page, shuttle all libraries from the Project Libraries
list to the Deployed Libraries list, and click Next.
</li>
[*]On the Finish page, name the profile <tt>HelloGui.prf</tt>, and click Finish.
</li>
[*]When JDeveloper asks you if you want to deploy now, click Yes.</li>
</ol>
JDeveloper will archive your application files and copy this archive and all
other required libraries to <tt><JDeveloper>/HelloGui</tt>.
Running the Application from the Command Line
<ol>
[*]Open a command-line prompt.
</li>
[*]Enter the following script.
Note: You may want to create a batch file containing this script. Be
sure to replace JDeveloper_Home with your JDeveloper home directory.
<pre>set __CLASSPATH_ROOT_DIR__=JDeveloper_Home\HelloGui
set CLASSPATH="%__CLASSPATH_ROOT_DIR__%\HelloGui.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\xmlparserv2.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\classes12.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\jdev-rt.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\swingall.jar"
cd JDeveloper_Home\HelloGui
jre -cp %CLASSPATH% helloGui.HelloApp</pre>
</li>
[*]Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.

New Features for Java GUI

Hello everyone!
Can anybody tell about new features in SAP GUI for Java. I think It's emasculate now. It doesn't contain New ABAP editor, Network graphic, normal Screen Painter... I really enjoy adding themes and other stuff, but when these functionality will be added?
Thanks.

Hi,
I use Java GUI from version 6.40, so i didn't know new ABAP editor for years. Once somebody shows me its features ...and I found that it is really good editor compared with previous Notepad-like frontend editor. But I have to say that customized version od Gvim used as external editor is in 90% better then new ABAP editor (the only problem is that double click on object doesn't work, but some workarounds are known for double-click on locally defined objects).
Graphical screen painter is generally good tool, but once I cannot find any feature (sorry, I forgot which one, it happens about 6 years ago). I ask a SAP guru sitting near me. He comes, switch graphical screen painter off and click to a box in non-graphical version of screen painter. Then he told me that some features are not accessible in graphical screen painter. It was last time I used graphical version of screen painter.
Themes? Works .... at least for me (Linux 32 bit and now Linux 64 bit too).
So I think that Java GUI is usable (at least on Linux/Mac, I am not sure how in works under Windows) but you cannot stick on all features (and maybe you can find better working variants of it). E. g. I have no problem with new ABAP editor, it would be much better for me, if I can open external editor clicking to "Change" button in SE38 directly instead of click plus selecting external editor from menu.

Pavel

JAVA GUI window content does not fill out when window is enlarged (Win,Mac)

I've been using the SAP JAVA GUI on a Windows XP workstation as well as a couple of MacBooks running OS X over the last year and a half or so, running versions from 7.10 r 7(maybe earlier) thru 7.10 r 10 (installed today.) The GUI has performed generally well on these platforms, but has one major irritation.
When I open certain pop-up windows, such as the SPAD [List of Output Requests > Status Description |http://img171.imageshack.us/i/screenshot20091006at241.png/|screenshot], it usually does not open a large enough window to display all the data - one must scroll horizontally and/or vertically to see the entire window content. The real aggravation is that if [one enlarges the window|http://img101.imageshack.us/i/screenshot20091006at242.png/|screenshot] so as to see more data, the resizing is ignored. The contents of the window are still displayed within the original window boundaries instead of filling out the expanded window.   It is not possible to get the entire window contents displayed, it is still necessary to scroll around.
What am I missing here?   How can I get window resizing to work correctly?   (Or is there a way to make such windows at least open up at a larger initial size??)
I only found one other thread in this forum, Sap gui screen size in ubuntu., which seemed to be addressing the same problem, but the suggestion was to apply the latest patch to the GUI and get JAVA 1.6.   One would think that since that post in 2008, any patches would have made it into the latest revisions. I'm already running Java 1.6.

Here's a [video capture of this behavior|http://img163.yfrog.com/i/sapresizebug.mp4/].
Given that installs on two separate operating systems have consistently misbehaved like this, I have a hard time believing it is something we are doing. (But not that hard...) I find it hard to believe that is the way these screens present on most SAP sites...
Any comments or suggestions would be welcome!

Error message: /opt/SAPClients/SAPGUI7.00/bin/libJPlation.so:ld.so.1:java:fatal:/opt/SAPClients/SAPGUI7.00/bin/libJPlatin.so:wrong ELF data format:ELFDATA2MSB
After I confirm the dialog, another error message appears:
JniAgiLibAdaptor.<init>: Cannot load JNI library.
I checked the supported OS, it doesn't contains Solaris 10 X86, but I think Solaris 10 was open source, just like linux, why doesn't SAP Java Gui support Solaris 10 X86? And now , how can I solve this problem?

What you see is what happens when the Java runtime running on Solaris 10 x86 tries to load a library which is compiled for SPARC.
Because of the native parts in SAP GUI for Java, compilations and installers are required for each OS - HW combination.
The supported platforms can be seen in SAP note 954572. For Solaris only SPARC is currently supported.
Because of the effort needed for compiling, testing, support etc. it is required to focus on OS - HW combinations widely used on desktop machines and Solaris 10 on x86 currently does not seem to be one of those.

Integrating Another Program Into A Java GUI

HI
I have 3 classes here. One is a Java GUI, the other two are involed in
stripping and processing of information off a webpage.
Of these latter two classes, one contains a main method which connects
to a webpage and reads the info off it, it calls the other class which
parses this information and holds the variables I need to create
buttons for the main gui!
Is it possible at all to integrate, the class that reads the webpage,
into, the Java GUI class.I need to do this to access the variables
that the parsing class is holding, as previously I have had to create
an instance of this class in the webpage reader class, but this was no
good to me as the GUI could not access this information, i.e can I
create an instance of this stripper at the begining of main in the GUI
class so as I can use the results for this for producing my buttons?
I've tried to do this but I am getting unresolved symbol errors. I was
wondering should I use global variables to hold the needed info also ?
Any help at all greatly appreciated,
Thanks
Gerry

I did what you're describing. Sounded simple enough. You put the same logic in main() into the applets init() and you can run as app or applet. Worked well in my IDE. Then the troubles start.
Visit
http://www.martinrinehart.com
and read the Article, Launching Applets. That will get you started on launching a Swing application. (Try my Sample, DawnPainter, to give you an idea about how nice this can be when it works.) I promise but don't deliver (yet) an article on the javascript library I wrote that solves all the problems. For non-commercial use you can get your own copy:

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

Any Java GUI Builder, please?

Hello everybody!
I have to develop a GUI in Java and I am totally rookie on this (Java & GUI development). What I would like to know is whether there is a kind of GUI Builder for Java with free license. I mean, a program which makes me easier to choose where to put the different menus and buttoms of the GUI.
I explain you a bit more. The IDE that I have to use is Eclipse. The GUI that I have to implement will be done in Java, but what I have to do is to convert a XML file in the GUI (read, parse?). This way I will be able to modify the XML using the GUI and then save the file again (this way the XML file will have been modified). I am working in a windows environment in spite of the GUI will be able to work in Linux too (thanks to a Java VM).
Thank you very much for your answers! And remember, I need a free license program.

My rec: don't use a GUI builder. At your stage, using one will hinder your ability to learn Swing and will set your Java education back at least 6 months if not more. Learn to code Swing by hand. They're not bad to use once you understand Swing, but even then, most professionals that I know do not use them in professional products (they say that the "ugly code" produced can be hard to maintain), but use them mainly for quick prototyping.Couldn't agree more, and I'm not even close to a professional level. I started out with Matisse in Netbeans. I spent quite some time learning how to use Matisse to build a rather large GUI. I spent even longer wrestling with it to try to get it to place components where I wanted them and at the size I wanted them. Then, after all the time spent on building the GUI, I found that I had to start over again from scratch because the code it had generated was so unnecessarily huge and fragmented that adding in the application's functionality was simply not feasible. Not to mention that after a certain point, Netbeans consumed so much memory to keep track of all the GUI elements that it crippled my PC (~997MB RAM) soon after opening the project.
So now I have to start over from scratch and have to hand-code it too. I would have been better off just starting by hand-coding in the first place. That way I wouldn't have lost so much time.
Besides, If you have to build a parser that builds the GUI from the contents of an XML file, I don't think any GUI builder would be of any use to you. Surely you'd have to study swing to a degree where you can hand-code a GUI with ease if you want to have any chance of building a program that can build a GUI on your behalf based on arbitrary XML content.
I could well be wrong because I'm still very much a beginner myself, but in my experience elsewhere I've always found that if you want to build a parser for something you're going to need to know whatever it is you're building a parser for like the back of your hand.

Opening HTML file from java GUI

Can someone please tell me how I can open a HTML file in Internet Explorer from a Java GUI,
I have an asssignment I am doing for college and I was toying with the idea of putting in helpfiles, for the program, can anyone tell me the easiest way of apcomplishing this???
Thanks in advance for your help,
Kaspah

Although this should answer your question, there are other (cross platform) ways to do what you want. As opposed to your "must have internet explorer" solution. Swing has a built in html viewer you might use, for example. I've been doing some reading on java/xml solutions. I don't consider myself knowledgeable enough (yet) to comment on that solution though. A delimited text file would be another solution. Useing that solution you could treat the file like a set of parrallel arrays on the hard drive and disply your text on pre-formated labels. Anyway, here is a link to you answer......

Web browser not started by java gui 7.20

Hello,
I use the java gui 7.20 on Linux.
When I click a link icon that points to a document on my content server, it does not start a web browser
to open the url.
Would you know how I could trace the problem?
Thanks in advance for your help

Hello,
you can verify with following steps:
Please enable tracing according to [note 683960|https://service.sap.com/sap/support/notes/683960] and add trace keys GMUX and C_GMUX by removing the comment symbols in front of the last two lines of the list.
Then perform the steps, which should result in opening that URL in the browser.
Open the trace file and search for "GMUX Request".
In case there are such entries, the corrections part of [note 1444941|https://service.sap.com/sap/support/notes/1444941] should solve your problem.
Otherwise you might want to create a support message on component BC-FES-JAV, so we can look into this.
Best regards
Rolf-Martin

Updating a Java GUI with c++

Hi,
I've been working with JNI for a few months now, but I am struggling with an important piece of the application I'm creating. What I have is a Java GUI which I use to create an existing c++ application through JNI. What I would like to do is have the c++ print all of its output to a window within the Java GUI. I thought surely others have wanted to do the same thing, but I have not found any threads addressing the idea. Here is what I've tried/thought of so far without success:
1) I could have Java poll the c++ application to see if there are any updates to be printed, but that seems clunky and I'm not even sure how well it would work. I would like it to print as it happens (i.e. have c++ tell the gui to print as it becomes available)
2) It seemed intuitive that I could simply pass the JNIEnv pointer, methodID, and the object to the c++ class to be stored for later use. But after it crashed I found a thread (http://forum.java.sun.com/thread.jspa?threadID=755242&tstart=225) which says you should never pass the JNIEnv (I don't know why). This same thread also gave some suggestions on how to attach to a current thread and then destroy, but also mentioned that once you destroy the VM, it can't be recreated and that won't work for me.
Any suggestions are greatly appreciated.
-Mark

And before anyone says "Google" or "check the documentation" I've torn through the MATLAB (mathworks) site and read every page that even mentions Java (beans or otherwise) and I've googled, trust me I've googled.
