Jrocket segfaults when running even trivial java app

Trying to run it on debian woody (2.2) it segfaults and on debian sid it just hangs
(can't control c it)
gdb on the core gives:
Core was generated by `/usr/local/jrockit/jre1.3.1/bin/i386/native_threads/java
-jrockit -cp . test'.
Program terminated with signal 11, Segmentation fault.
#0 0x2ad0e38d in ?? ()
stracing it on woody stops it segfaulting and I get these messages

Hi Chris.
I agree, I think it may be something in the OS like glibc or perhaps some other lib.
Unfortunately we don't test on debian, and we don't certify on it. 8-(
You might compare glibc versions between your version of debian and the version of
redhat we support, and make them the same if possible. Other than that I'm not sure
what else to suggest other than go with RedHat.
Maybe someone else reading this forum can offer a better suggestion.

Hi Michael!
I tried both the old version and the 7.0 version on debian, and it didnt work.
Both versions worked fine on RH.
maybe a problem with the glibc.
tell me if you need any config info or want me to run tests.

Hi.
Hmm, weird. I tried your test app on RH linux with jrockit and it worked fine.I
gather you are not getting a jrockit.dump file, so it's an initialization problem.
I don't have any good suggestions. You might try the new release of JRockit7.
Your copy of jrockit may have been corrupted.

New Output Module install generates an i/o error when running even on a single image.

Adobe *had* removed the Output Module from Bridge, and I see now there is a (tedious) "manual" install to "reinstate" the module available online, but it is not functional. It generates an i/o error when running even on a single image.

I'm afraid this is not helping the OP
There are already to many having this I/O problem showing in several other threads and in this forum there is still no solution found. Can you pass this on to Adobe Tech please?

When running a "stand-alone" APP..how do I send midi from Logic?

Hi all,
When running a "stand-alone" APP..how do I send midi from Logic?.....Please no IAC stuff it doesn't work.......thanx
SvK

using IAC here no problems. works very well.
you can host your au's in another app such as soundflower or au lab, but you are still going to need to get it to hear midi. you can use physical midi ports with something like a MTP midi interface, and getting the midi by routing the out of one port to the in of another (midi loop) but you have to be careful logic doesn't listen to the same midi signal or everything will jam up (midi feedback).

Server Error: Unexpected Error when running Napa SharePoint 2013 App

I am getting an error "Server Error : Unexpected error" when I try to run a SharePoint 2013 app in Napa Development environment.
It starts the process normally but after it shows "Uninstalling previous version" it throws the error. This has been happening since yesterday.Someone help

I have a solution to the problem. I had a folder with a JSON file. On renaming the file to .txt, the app ran normally. I believe .json files are not supported in SharePoint hence the error.

Error when trying to run my first Java app

Okay, Im new to Java programming. I started a day ago :). My question is after I compile my application like so.
javac TestGreeting.javaIt give me a .class file. So the next step is I want to run it so I do the following.
java TestGreeting.classWhen I run this I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: TestGreeting/classCan some one tell me what is going on? I am running Mac OSX Leopard on a MBP. I have the latest Xcode Tools which is 3.1 if I am not mistaken.
Thanks everyone. Go easy on a newbie :)

The argument for the java command is the fully qualified Class Name. It is not a file name or path. You provided a file name. The JVM tried to find a class named 'class' in a package named TestGreeting. Most likely, you should have typed "java TestGreeting"
Here is a link to a tutorial, and the Getting Started section includes a section for problem resolution.

So summerizing some of what was said before and some of that wasn't.
jGrasp is a simplistic IDE. When you pop a dos window from it it sets up the windows correctly to run your program. When you open a regular command window you must do the same yourself.
>
Exception in thread "main" java.lang.NoClassDefFoundError: keyboard/javaJava runs "classes". The command that you typed above meant that you were trying to run a "file". Specifically the file "keyboard.java". The two are not the same. There is however a relationship. When the source code, in this case inside of "keyboard.java" is compiled it produces a file called "keyboard.class". Insided of the file there is a "class" called "keyboard". Notice that the name of the class does not have either .java nor .class on the end of it.
The VM (the 'java' command) finds a "class" using the class path to search files of various types for the class (again keep in mind that files contain classes but they are not themselves classes.)
You can add to the classpath using the Sun VM using either command line options or environment variables. As noted in some of the previous messages those are "-cp" and "CLASSPATH". It is important to note that that does NOT fully specify the class path. But for your purposes it is sufficient to think of it as doing so.
The 'default' setting for the part of the class path that you normally set (like via '-cp') is the current directory which is specified by the ".". So normally the following are equivalent.
java -cp . keyboard
java keyboard
The reason the VM could not find your class when you opened the dos window yourself is because you were in the wrong directory. If you had been in the directory with the file "keyboard.class" then it would have worked (if you have not messed with the environment variable "CLASSPATH".)
So if your class file has the following location: c:\myapps\java\keyboard.class then you can do the following.
1. Open a console window
2. Type "cd c:\myapps\java"
3. Type "java keyboard"
If the above does not work then you are in the wrong directory or the env variable CLASSPATH has been set to something.

Lion freezing when running Adobe CS5.5 apps

Is anyone having this issue or can you offer any troubleshooting help? I installed Lion a couple of days ago on one of my computers (2 x 3 GHx Dual-Core Intel Xeon with 2 GB 667 MHz EEC DDR2 FB-DIMM). When I open up any of the Adobe CS5.5 apps and begin working, after a while, I get the spinning beach ball. I had no issue before in Snow Leopard. Do I need to up my memory or are they just not playing together well?

4GB memory would be better for Lion.

How to enforce a login screen when running a Web Dynpro app?

Hello,
In Web Dynpro for Java there is a way to set authentication property to true and by that enforcing a login screen in case someone is browsing this application outside of an authenticated context (for example, the portal).
My question is: How do I do this for Web Dynpro for ABAP?

Roy, are you familiar with that http://help.sap.com/saphelp_nw04s/helpdata/en/ff/c7de3fc6c6ec06e10000000a1550b0/frameset.htm ?

How do I run multiple java apps in one JVM to reduce memory use?

Hi all,
I saw an article either on the web or in a magazine not too long ago about how to "detect" if the app is already running, and if so, it hands off the new instance to the already running JVM, which then creates a thread to run the Java app in. As it turns out, my app will be used in an ASP environment, through Citrix. We may have as many as 50 to 100 users running the same app, each with their own unique user ID, but all using the same one server to run it on. Each instance eats up 25MB of memory right now. So the question is if anybody knows of a URL or an app like this that can handle the process of running the same (or even different Java) apps in one JVM as separate threads, instead of requring several instances of the JVM to run? I know this article presented a fully working example, and I believe I know enough to do it but I wanted ot use the article as a reference to make sure it is done right. I know that each app basically would use the same one "launcher" program that would on first launch "listen" to a port, as well as send a message through the port to see if an existing launcher was running. If it does, it hands off the Java app to be run to the existing luancher application and shuts down the 2nd launching app. By using this method, the JVM eats up its normal memory, but each Java app only consumes its necessary memory as well and doesn't use up more JVM instance memory.
Thanks.

Kill opened IE, when killing Swing Java App

I am creating menu items which fire off an IE window to a URL. However, when app is closed the Java process that runs the app blocks waiting for the executed browser to terminate before its shuts itself down. This has potential repercussions as the Java VM hangs around in the mean time, holding resources. Can anyone point me in the direction of how to kill the opened IE window when I kill the java app? I would greatly appreciate any help. :-)
This is the code in question:
userManualMenuItem.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
     try
     String url = System.getProperty("EASEUserManualURL");
     Runtime r = Runtime.getRuntime();
     Process p = r.exec("iexplore " + url);
     catch(Exception exception)
          Logger.getLogger().logError("Error opening Intenet Explorer to show EASE user manual.\nCause: " + exception.getMessage());
     });

Wouldn't it solve the problem if you made the exec() call on a daemon
thread? I wouldn't advise making exec() calls on the EDT in any case. 1 - You can't call exec() on a Daemon thread. You can call Runtime.exec() inside of a spawned thread that has been marked as a Daemon. This would be preferably rather than launching off of the EventDispatcherThread as itchystratchy stated because....
http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html
I'm sure there's a way you can just launch the user's default browser isn't there?2. - I use http://browserlaunch2.sourceforge.net/ in my current app, it launches whatever application you have associated for that file type to view that file. Also supposedly cross platform. You will not get Process reference to the launched app though. I've tested successfully on Win 2000 and XP up to now but it will allow you to close your Java application and leave any launched browsers open if that is what you are looking for or as you asked for earlier keep a collection of launched Process references and destory them when your user is closing your app.

Show java app name in task manager

Right now if I run 10 java apps in seperate JVMs, it shows 10 copies of java.exe in the task manager on Windows NT/2000.
Does anyone know a way to change the image name when I launch my java apps, or a simple way to create a java "application" for windows (for example, NetBeans shows up as Netbeans.exe even though it is a java app).
Thanks!

Turns out you can copy java.exe to anyname.exe and execute anyname.exe just like java.exe.
DOH!

Java app with web service and servlets

Hi. I intend to make a java application which exposes some methods as a web service and as jsp/servlets. It's core functionality is not really web centric, but its more a java app with a web tier. I am not sure about how the architecture of such a system would look like using the java platform. I currently see three options:
1. Run everything in a servlet container like tomcat. I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web services. However, it would be really easy just to put everything into tomcat and use ServletContext to maintain some global objects.
2. Use a Java EE to seperate application/business logic and data access into session beans and entity beans. I hesitate to this because it seem a bit overkill because the system isn't very big or complex right now. It also means that I would have to learn to use EJB's instead of just using some POJOs.
3. Run the web tier in a servlet container and the main app in a separate JVM, and then connect the tier by sending serialized objects over TCP sockets. I don't like writing network code but at least there is some separation of the tiers.
What would you do? Maybe I have overlooked a much better solution to the problem?
Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) instead of the something quick and dirty that is hard to defend.

Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) That pretty much makes it impossible then.
1. A "Right" solution is generally only proven by time.
2. It requires a great deal of knowledge about the business domain.Yeah, you are right. Let be try to rephrase it. What solution (pattern) would be considered the most common or appropriate when you have a Java App and want to expose a few methods as a website and web service?
I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web servicesHuh? Do you already have an exposed web service? If you already have a server which other clients communicate then where does this functionality that you don't want to be tomcat running now? Or where do you think that you want to run it? And if you are or do run it somewhere else then tomcat could access it the same way any other client accesses that server.Sorry, that sentence was written badly. I don't have anything right now. What I meant to write was that I will have a lot of application scope data, objects that are kept in memory as long as the server is running, shared by multiple servlet instances.

Killing Java app from C

Ive seen this question posted before, but never found a good answer. I am invoking a JVM from a legacy C app (via JNI_CreateJavaVM) and I want to be able to end the JVM and have the C app continue. The problem is that a call to System.exit() from inside the java app causes the entire native process (not just the JVM) to be killed. A call to DestroyJavaVM() does not unload the
JVM (as it claims it does in the API documentation).
Currently, the Java code calls dispose and System.gc (for good measure) on exiting, although this doesnt completely kill the java app. If the user wishes to invoke another Java app, the C code uses JNI_GetCreatedVMs to see if one already exists, and if so uses AttachThread (or GetEnv) to hook to the existing JVM to run the new Java app. The problem with this is with complicated GUI apps, the machine soon hits a wall, I guess because of un-gc'd stuff laying around.
Is there a way to kill the app from java without using System.exit or is there a way to unload the JVM from the C app?

Unfortunately I am running into the same issues using JDK1.4 on Win32. Basically the call to jvm->DestroyJavaVM() is NEVER returning. This seems to mainly be a problem when you use classes which require a native class loader to load native libraries. EX: classes which use System.loadLibrary("some native library"). Has anyone found a workaround to allow us to stop the jvm from the native side when these are present?
Also if anyone in interested - this is the exact c++ code I am currently using:
    if(vm != NULL) {
         * Detach the current thread from the vm so that it appears to have
         * exited when the process has detatched from the dll.
        if (vm->DetachCurrentThread() != 0) {
            MessageBox(NULL,"Could not detatch the Java Virtual Machine","DEBUG Info",MB_OK+MB_ICONEXCLAMATION);
        MessageBox(NULL,"Try to destroy the VM","DEBUG Info",MB_OK+MB_ICONEXCLAMATION);
        vm->DestroyJavaVM();
        vm = NULL;
    MessageBox(NULL,"JVM destroyed successfully","DEBUG Info",MB_OK+MB_ICONEXCLAMATION);Basically all the calls succeed except the vm->DestroyJavaVM(); including the call to detatch the current thread from the VM! Am I missing something obvious? Is this a known bug? Anyone know any workarounds? Aany and all constructive comments are welcome.
