Unidentified subject!
i am trying to use the ready type of linked list and i found that there is
a bug in the add.(index, object) method.
i am trying to read the index after each addition is performed and the
value i get is always 0.
when i am trying to extract data from the list thow the index is working
as expected and i can move about doing all the described operations
I am attaching a sample programm to demonstrate the problem
tks for the help

Problems with kernel 2.2.14
RedHat 6.1 JDK 1.2.2-RC4 (native threads) I just upgraded the kernel on one of my test boxes today from 2.2.12-20 (RedHat 6.1 stock) to 2.2.14. No other software changed. My server now fails to start with a java.lang.OutOfMemoryError when doing a java.lang.Thread.start. Booting my old kernel makes the problem go away. Starting with -Xmx256m or -Xmx512m makes no difference. I saw this problem 2 weeks ago on an SMP box, but thought it was related to that configuration. It was also running 2.2.14. Has anyone else seen this? -John PS. The TCP connection limit problem I wrote about last week was in our code. Sorry for the wasted bandwidth.

If you're looking for a function that will return the current size of
the list, try the LinkedList.size() method. The function you're using,
ListIterator.nextIndex(), is working as advertised - the only thing that
should change its return value is your use of ListIterator.next() or
ListIterator.previous().
If this were a bug, it's not likely to be Linux-specific... the
container classes are themselves implemented in Java and work the same
everywhere.

Java3D and Linux Installation
Hello everybody, I tried to install java3d 1.1.3 and jdk 1.2.2, both from blackdown on Suse Linux 6.3. Then I'll get the following error-message (see at end of mail) I have seen some similar problems in your archive. Is there a solution for this problem? After that I tried to install the blackdown version of java3d 1.1.1 and I am getting the following error: Exception in thread "main" java.lang.UnsatisfiedLinkError: /usrs3/jdk1.2.2/j re/lib/i386/libJ3D.so: /usrs3/jdk1.2.2/jre/lib/i386/libJ3D.so: undefined sym bol: glTexImage3DEXT at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java, Compiled Cod e) at java.lang.ClassLoader.loadLibrary(ClassLoader.java, Compiled Code ) at java.lang.Runtime.loadLibrary0(Runtime.java, Compiled Code) at java.lang.System.loadLibrary(System.java, Compiled Code) at javax.media.j3d.UniverseManager$1.run(UniverseManager.java, Compi led Code) at java.security.AccessController.doPrivileged(Native Method) at javax.media.j3d.UniverseManager.(UniverseManager.java, Comp iled Code) at javax.media.j3d.VirtualUniverse$2.run(VirtualUniverse.java, Compi led Code) at java.security.AccessController.doPrivileged(Native Method) at javax.media.j3d.VirtualUniverse.(VirtualUniverse.java:464 ) at HelloUniverse.(HelloUniverse.java, Compiled Code) at HelloUniverse.main(HelloUniverse.java, Compiled Code) I really need your help Thanks in advance Desiree The first error message starts with: > SIGSEGV 11* segmentation violation > si_signo [11]: SIGSEGV 11* segmentation violation > si_errno [0]: Erfolg > si_code [0]: SI_USER [pid: 0, uid: 0] > stackpointer=0x44b5ddfc > > Full thread dump Classic VM (1.2.2-L, green threads): > "J3D-UniverseManager-1" (TID:0x40f6c5b0, sys_thread_t:0x86a52e8, > state:CW) p > rio=4 > at java.lang.Object.wait(Native Method) > at java.lang.Object.wait(Object.java:420) > at > javax.media.j3d.UniverseManager.renderAction(UniverseManager.java:399 > ) > at javax.media.j3d.UniverseManager.run(UniverseManager.java:357) > "J3D-SoundScheduler-1" (TID:0x40f74a20, sys_thread_t:0x86a3d38, > state:CW) pr > io=4 > at java.lang.Object.wait(Native Method) > at java.lang.Object.wait(Object.java:420) > at > javax.media.j3d.SoundScheduler.runMonitor(SoundScheduler.java:488) > at > javax.media.j3d.SoundScheduler.checkState(SoundScheduler.java:229) > at javax.media.j3d.SoundScheduler.run(SoundScheduler.java:387) > "J3D-View-1" (TID:0x40f7a478, sys_thread_t:0x842da40, state:CW) prio=4 > at java.lang.Object.wait(Native Method) > at java.lang.Object.wait(Object.java:420) > at javax.media.j3d.ViewThread.renderAction(ViewThread.java:298) > at javax.media.j3d.ViewThread.run(ViewThread.java:193) > "J3D-Traverser-1" (TID:0x40f7a100, sys_thread_t:0x85182b0, > state:MW) prio=4 > at javax.media.j3d.Traverser.traverse(Traverser.java:1605) > at javax.media.j3d.Traverser.traverse(Traverser.java:761) > at javax.media.j3d.Traverser.traverse(Traverser.java:847) > at javax.media.j3d.Traverser.run(Traverser.java:2124) > "J3D-Behavior-1" (TID:0x40f70c80, sys_thread_t:0x84dc7a8, > state:R) prio=4 > at java.lang.Object.wait(Native Method) > at java.lang.Object.wait(Object.java:420) > at > javax.media.j3d.BehaviorScheduler.runMonitor(BehaviorScheduler.java:1 > 001) > at > javax.media.j3d.BehaviorScheduler.run(BehaviorScheduler.java:920) > "J3D-Renderer-1" (TID:0x40f7a6e0, sys_thread_t:0x86092e0, > state:R) prio=4 > at javax.media.j3d.Canvas3D.createContext(Native Method) > at javax.media.j3d.Renderer.run(Renderer.java:211) > "J3D-Input-1" (TID:0x40f73398, sys_thread_t:0x86236e8, > state:CW) prio=4 > at java.lang.Object.wait(Native Method) > at java.lang.Object.wait(Object.java:420) and goes on for pages ... -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Problems with HotJava 3
Hi, I can't start Hotjava 3 on my RedHat 6.1 box. The app starts : I get the nice splash screen. Then I get the following error message: Exception in thread "main" java.lang.Error: unable to find a .bdtd file : lib/html32.bdtd at sunw... ... [[[ Failed to load scripting engine ]]] I'm using Blackdown JDK1.2pr2. Basically it runs of a big jar file, and when I unzip it I can see that the lib/html32.bdtd is there. Any idea, or anybody had the same problem? Should I upgrade to 1.2.2? Thanks a lot, Pierre -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

JAVA_HOME
Hi, I installed IBMJava118-JRE-1.1.18 on my redhat system, and set all the path & classpath. The JAVA_HOME I set to /usr/jre118/bin, and I'm try to install IBMWebAS-core-2.03-1.i386.rpm using rpm -ivh. It give me the error: Cannot find where java is installed on this system. Please make sure the JDK or JRE is installed and set JAVA_HOME before installing this package. I run the jre, it is working. Can anyone tell me the JAVA_HOME is set correctly? Louis

And the version of IHS (modified Apache) they ship is also too old. I'm not saying it's not possible, but waiting for WAS 3.0 might turn out to be the best bet. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
