S.u.S.E 5.3 and Java opinions welcome
Hi,
Has any one had any problems with S.u.S.E 5.3 glib
and JDK, JSDK, and JavaWebServer1.1 ?
I am going to move to S.u.S.E from slackware if all
goes well, as I need glib and rpm support.
Any tips would be great.
Many thanks
Matt

RMI Help needed...
Fellow Blackdown'ers: I am using the jdk1.1.6v5 port of Java, running apache at home. I was wondering what I need to install and how to go about it to get into RMI Development. Are there any good tutorials for installing RMI with apache. Any help on this matter would be useful. Dan.
Re: Sun's Commitment to Port JDK 1.2 to Linux
My understanding (this release that you link to is very nebulous...it doesn't really say the level of support) from what SB has said on this list is that they are just giving the team early-access to the source code AND the compatibility checker (JCK). Is this all they are doing, or are there engineers at Sun Micro actually writing Linux code? And, will this port be advertised/available on Sun's page with the other ports (Solaris and Windows)?

RE: Some weird security problems in netscape
I ran into a similar problem when I had two applets in the same HTML document and wanted to send mouse events from one to the other via network sockets (I was doing it to prove to myself that I could, not for any other really practical purposes). I could get it to work okay using appletviewer, and Microsoft's Internet Explorer Version 4 (after disabling the network security checking).

Re: Some weird security problems in netscape
Hi, I think I figured out a hack to avoid signing (although I should start using some form of certificates really soon). Simply put: Encode raw data in a standard lossless image format, fetch over the net using getImage (and a media tracker perhaps) and then decode it by grabbing the pixels of the image It sounds really hacked, but I think it can work. Perhaps the plugin approach is better. Has anybody tried using it under Lunx? Dimitris I ran into a similar problem when I had two applets in the same HTML document and wanted to send mouse events from one to the other via network sockets (I was doing it to prove to myself that I could, not for any other really practical purposes).

Uncle George's Alpha Port
Hi, The archives don't show e-mail addresses or else I'd write to Uncle George directly. Anyway, I understand there is some problem with your Web provider. I'd encourage you to upload your port of JDK to Alpha to sunsite or someplace like that. I believe there is significant interest in it, and it's a shame to have a situation where nobody can use the port to such an excellent machine because your web provider is being nasty. Sunsite has many, many mirrors and once it's on there, this ought to eliminate all future problems. Is there any other way to get it from you? Thanks, John Goerzen
TYA1.1v4 released
Hi, The _latest_ TYA JIT compiler release you find on TYA's ftp home: ftp://gonzalez.cyberus.ca/pub/Linux/java/tya11v4.tgz Some notes: This release introduces a new JNI approach. If you have any JNI-trouble report this please and meanwhile disable JNINATIVENEW. If you are runing an newer 2.1.x kernel, it is possible you have to disable EXCEPTIONS_BY_SIGNAL. For some other news and changes look into Changelog and README files. Enjoy, Albrecht

pipe question
This is a general Java question, although it might (possibly) point to a bug in the v5 port or in 1.1.6 itself. Under what circumstances does PipedInputStream.read() or PipedOutputStream.write() throw an IOException for "Pipe broken?" Intuitively, what I think should happen is that a pipe throws an IOException if either (a) it hasn't been connected to another pipe, (b) close() was called on the pipe it had been connected to, or (c) finalize() ran on the pipe it had been connected to. However, I'm getting a "Pipe broken" IOException even though the pipe is connected to another pipe and neither close() nor finalize() has been run on either the input pipe or the output pipe. *If* what I just described were true, would it be a bug in Java, or am I misunderstanding the cases when "Pipe broken" is thrown? Thanks very much for your help; this problem is causing a nasty bug just prior to release. Best, daniel dulitz Valley Technologies, Inc. Peak Performance Real-Time DSP State College, PA

This null pointer exception is simply inexplicable (and it happes only in Netscape). And now something completely different (in the same topic as usually ;-} ) Has anybody tried to work with serialized applet. It seems that the lovely browsers totally refuse to cooperate. To explain. I serialize the very sam applet (it is unbelievable, I can't get it worl ouside the appletviiewer!!!). The appletviewer is able to deserializ the applet (using the object tag in the html) and have it run normally. However both browsers(netscape in linux.win and the M$ stuff) simply display NOTHING when I deserialize tha applet!!! Even worse, I try a applet context dump in netscape and I get : # No active applets or applet contexts. Has anybody attempted something similar (and got it work)?

native thread question
I've been experimenting with the new native threading code, beating on it to see how it holds up, doing that sort of beta test that people dream of. (I've found a memory bug, but that's for a different piece of mail...) Anyway, while watching the process table, I noticed that most of the threads that are created are niced to at least 5, with one or two being at 10, and another one or two (my threads?) are at 0. I figured the thread that was niced at 10 is the garbage collectiong thread, and a few of the other threads at 5 are created by the VM at start-up for various VM tasks. This got me curios as to what determines the niceness. By the java spec, thread priorities can be ignored, but I'm wondering that if in this case, are thread priorities being mapped to a niceness level? Any comments? Keith -- Keith T.

shuJIT: another Java/Linux JIT
You can tell the Java/Linux thing has finally taken off when more has happened than is announced on this mailing list. While browsing the ever-helpful Java Linux News http://www.w3com.com/paulcho/javalinux/ I found a link to another JIT for Linux, shuJIT, at http://www.shudo.net/jit/ Executive summary: also works with FreeBSD, says performance is about like TYA, interested in working eventually with thread migration. The author is in a research group working on "OpenJIT", a project to make the JIT itself be controllable by Java to make it easier to tune. Looks quite interesting.
bug in native thread garbage collecting?
I've got a jserv compiled into apache and I'm using it to run a servlet that does an RMI call for ever doGet that it receives. While doing a stress test with the new native thread support, it looks like I've come across a bug related to memory management or thread creation. To do the stress test, I had two computers repeatedly doing a request on the servlet. Back to back, non stop. (It was a pretty unrealistic load for what the web server would do, but I'm also showing that apache on Linux can stand up to this abuse.) After doing 1000 hits in about 69 seconds, the vm would seg fault. The first time I did a trial I had a System.gc() at the bottom of the doGet to force a clean up and I got this as the stack trace: SIGSEGV 11* segmentation violation stackbase=BF1FFE7C, stackpointer=BF1FFA10 Full thread dump: "Thread-1002" (TID:0x40bd3d98, sys_thread_t:0x8183758, state:R, thread_t: t@1040375, sp:0x0 threadID:0x0, stack_base:0x0, stack_size:0x0) prio=5 "Thread-1001" (TID:0x40bd40d0, sys_thread_t:0x8109698, state:R, thread_t: t@1039350, sp:0x40fff334 threadID:0x1d1d, stack_base:0x40fffe7c, stack_size:0x20) prio=10 java.lang.System.gc(System.java) EngineSnoopServlet.doGet(EngineSnoopServlet.java:125) javax.servlet.http.HttpServlet.service(HttpServlet.java:486) javax.servlet.http.HttpServlet.service(HttpServlet.java:575) org.apache.jserv.JServConnection.run(JServConnection.java:349) "ConnectionExpiration-10.0.4.50:18287" (TID:0x40bd2a90, sys_thread_t:0x81110d0, state:CW, thread_t: t@18450, sp:0xbd7ff830 threadID:0x191a, stack_base:0xbd7ffe7c, stack_size:0x20) prio=10 This lead me to beleive the bug was in memory management since it appeared to be happening in the call for garbage collection.

Again, after 1000 hits, the VM seg faulted, only this time I got a different stack trace: Full thread dump: "Thread-1005" (TID:0x40c253d0, sys_thread_t:0x812f510, state:R, thread_t: t@1040375, sp:0x0 threadID:0x0, stack_base:0x0, stack_size:0x0) prio=5 "ConnectionExpiration-10.0.4.50:18287" (TID:0x40bd3630, sys_thread_t:0x81d0018, state:CW, thread_t: t@14350, sp:0xbdfff830 threadID:0x2629, stack_base:0xbdfffe7c, stack_size:0x20) prio=10 sun.rmi.transport.tcp.TCPChannel$Reaper.run(TCPChannel.java:458) java.lang.Thread.run(Thread.java) "ConnectionExpiration-10.0.4.50:18010" (TID:0x40bd2528, sys_thread_t:0x81a12e8, state:CW, thread_t: t@13325, sp:0xbe1ff830 threadID:0x2627, stack_base:0xbe1ffe7c, stack_size:0x20) prio=10 sun.rmi.transport.tcp.TCPChannel$Reaper.run(TCPChannel.java:458) java.lang.Thread.run(Thread.java) "Cleaner" (TID:0x40bd1220, sys_thread_t:0x81b9000, state:CW, thread_t: t@12300, sp:0xbe3ff820 threadID:0x2625, stack_base:0xbe3ffe7c, stack_size:0x20) prio=10 sun.rmi.transport.DGCClient.run(DGCClient.java:621) java.lang.Thread.run(Thread.java) "LeaseRenewer" (TID:0x40bd10d8, sys_thread_t:0x81b8ee0, state:CW, thread_t: t@11275, sp:0xbe5ff820 threadID:0x2624, stack_base:0xbe5ffe7c, stack_size:0x20) prio=10 sun.rmi.transport.DGCClient.doRenewal(DGCClient.java:677) sun.rmi.transport.DGCClient$LeaseRenewer.run(DGCClient.java:936) java.lang.Thread.run(Thread.java) "Reaper" (TID:0x40bd0fe0, sys_thread_t:0x81b7198, state:CW, thread_t: t@10250, sp:0xbe7ff830 threadID:0x2623, stack_base:0xbe7ffe7c, stack_size:0x20) prio=10 sun.rmi.transport.Reaper.run(ObjectTable.java:199) java.lang.Thread.run(Thread.java) "ConnectionExpiration-10.0.4.50:1099" (TID:0x40bd0d18, sys_thread_t:0x81a2ba0, state:CW, thread_t: t@9225, sp:0xbe9ff830 threadID:0x2622, stack_base:0xbe9ffe7c, stack_size:0x20) prio=10 sun.rmi.transport.tc
Re: Some weird security problems in netscape - getting worse + Wht'a wrong with these browsers?
Then I built an applet which displays an image and I didn't see any NullPointerException. You can see the code and the web page: http://lcomp98/carlos/applets/Imagen.html The same directory contains Imagen.java, Imagen.class and maquina.gif Any question?

Open Java, take 2
Well, it's almost like they read java-linux "In response to some disgruntled elements of the Java community, Sun Microsystems in coming weeks will announce a new process that allows non-Java licensees to have a role in defining new Java APIs across the spectrum of Java classes."

GTK+ AWT peer library for Java
I've started a project to implement Java AWT peers in GTK+ (instead of in Motif). Besides breaking the dependency on Motif, I believe that this will make it simpler to integrate Java apps into the Gnome desktop project. (See www.gtk.org and www.gnome.org). I'm intending to add this to the JDK1.2 for Linux as an extension, so that either the existing Motif version or my new GTK+ version of the AWT can be used, depending on personal preference. I noticed in the archives that this was discussed a few months ago, but I haven't seen anything on this topic recently recently. I happen to work on Java at Sun, so I have access to the JDK1.2 sources, although this is not an offical Sun project - I'm strictly doing it in my spare time. I hope to have something of alpha quality, that other developers can also work on, by the time JDK1.2 is released. Nigel Gamble[EMAIL PROTECTED] Mountain View, CA, USA. http://www.nrg.org/
1.1.6,1.1.7: cannot find ldd
The lastest versions of the x86 blackdown jdk report the following error when starting java (though things work fine otherwise): /usr/local/java/bin/checkVersions: ldd: command not found This is on a system that was originally RH5.0, since upgraded to RH5.1, pretty vanilla (compiled apm support into the kernel but no other changes). I don't see 'ldd' on the system - what is this? --- j.p.lewis [EMAIL PROTECTED] 012 345 6789 //www.idiom.com/~zilla
