Problems of JavaPlugin 1.2.2 with KDE 1.1.2
Hello, does anybody knows if there are problems of the JavaPlugin 1.2.2 with the KDE 1.1.2 desktop? When I start a Java2 applet in the netscape 4.73 navigator on my linux (Suse 6.0, glibc2.1.2) having KDE 1.1.2 running, netscape quits without any error message. But running the same applet running fvwm2 all works fine. Any ideas? Thanks, Lars. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
Java3D
Hi everyone, I just wanted to give a status update on my experiences with Java3D and hardware acceleration: The problems I had with Java3D obviously resultet in bugs in Utah-GLX, so Java3D is not really to blame (the behaviour was just a bit confusing). Here are some of my results: GFX hardwareOpenGL implementation Result -- Matrox G400 XFree 3.3.6 / Mesa 3.2 /Works. VERY slow. Software rendering Matrox G400 XFree 3.3.6 / Mesa 3.2 /Does not show Utah-GLX-2626 textures. Crashes occasionally. Non-textured rendering is reasonable fast. nVidea GForce XFree 3.3.6 / Mesa 3.2 /Same as G400. Utah-GLX-2626 Matrox G200 XFree 4.0 (includes Mesa 3.3) Black picture. The / DRI Framerate is impressive however. ;-) Matrox G400 XFree 4.0 (includes Mesa 3.3) Crashes. / DRI Matrox G400 Xi-Graphics Accelerated-X Works. VERY fast. (Demo version 1.1) -- So for now the only viable option I know of if Accelerated-X. Using a 3Dfx board with hardware accelerated Mesa on Glide probably also works, but I have not tested this. The XFree 4.0 test are not finished yet. A test with the GForce, as well as using different kernel versions might give other results. bye...

can't find libjava.so.
(the first attempt at this message seems to have failed - sorry for any duplication) hi all, i am not a linux person (though the more i use it the more i like it) so please go slowly. we are working on a cross-platform (mac/win/linux/solaris) java solution. right now im working on the linux piece - we're using redhat 6.2 and blackdown java 1.2.2. the solution interacts with various cds and creates a database on the users hard drive of info based on those cds. to get the program working i was using the following shell script: #!/bin/bash cd / cd /usr/local/jre1.2.2/bin export CLASSPATH=/root/myDirectory:/root/myDirectory/myJar.jar bash java myApplication the problem with that shell is that because it leaves the prompt in the jre/bin directory any reading/writing of files defaults to there. so i tried the following: #!/bin/bash export CLASSPATH=/root/myDirectory:/root/myDirectory/myJar.jar: /usr/local/jre1.2.2/bin export PATH=$CLASSPATH:$PATH bash java myApplication this does not work instead i get a "can't find libjava.so." error any help would be appreciated please feel free to email me directly at [EMAIL PROTECTED] tia ben -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Starting The JVM from C++
Hi, Can someone please volunteer to send me a small code that uses C++ to start the JVM. I know that this comes under JNi, but I have found it difficult to get the solution eventhough I have refered a lot of books. It will be great if I can get a code which I can use on VC++ also. Thanks Hrishi.
XML Technology Update & Resources
Hello, Being that you have expressed interest in XML technologies at IBM. We thought that the following new technology update (Xeena) and XML tutorials may prove valuable to you. If you would not like to receive further information about free XML resources form IBM, please reply with "No More XML from IBM". Regards, Shailendra XEENA ( Visual XML Editor) Has Been Updated - Xeena 1.2EA - an Early Access release with experimental W3C XML Schema support (partial). This release also contains many new features, including DTD to XML-Schema import, search and print capabilities, Keyboard Shortcuts and more. http://www.alphaworks.ibm.com/tech/xeena?open&l=2xm4jlst,t=xena JMS, XML, and the Heterogeneous Enterprise Most computing environments today are characterized more by a patchwork of different platforms than by an adherence to any one platform. The Java Message Service (JMS), together with the Extensible Markup Language (XML), extends the promise of integration to this heterogeneous environment. This article demonstrates how to use JMS to create and distribute XML-based messages to Java and non-Java applications alike http://www.software.ibm.com/developer/library/heterogeneous/index.html?open&l=321,t=gr,p=jmsxm The data melting pot - In this demonstration of how to exchange data with other companies through XML, find solutions to some of the problems inherent in B2B communication.

Re: Security bug in a major fraction of VMs
Joseph Shraibman wrote: > > And this is a big security problem? Access specifiers are meant to > protect programmers from doing stupid things, not protect security. Of IMHO, I'd say they are also there to protect security. Encapsulation = Security. References to objects can be handed around like, say, referenes to files. We can give a whole lot of people a handle to a file that contains, say, our private key or our address book. And that doesn't (and shouldn't) mean everybody can open it and look at what's in there. With this bug and given a reference to a graph of objects, it seems once can traverse and examine the entire graph without any problem, breaking all encapsulation. Seems easy - just introduce a class that does it. > course if you hack the jvm you will be able to get access to a private > field. So just what is the security concern here? No need to hack the jvm.

For purposes of backwards compatibility, the default format checks performed by the Java 2 SDK's virtual machine are no stricter than the checks performed by 1.1.x versions of the JDK software. The -Xfuture flag turns on stricter class-file format checks that enforce closer conformance to the class-file format specification. Developers are encouraged to use this flag when developing new code because the stricter checks will become the default in future releases of the Java application launcher.

Desperately looking for documents about compiler internals
Greetings,
for my diploma thesis, I am looking for information about the java
compiler, especially documents regarding the generation of the
abstract syntax tree in javac.
Currently, I am trying to understand the sun source code ("Community
Source" fomr March). Can anybody advise about places in the code so I
can inspect a tree that is built or put it into a file?
Any help is appreciated greatly.
