Re: Beans
George, A worthwhile book to consider is: "Developing Java Beans", Robert Englander, O'Reily It goes into much more depth than the rather superficial and pat "Teach Yourself Beans in 21 Days" book by Sams books. - chris George Karabotsos wrote: > > Hi, > > could anybody give me some starting points of how I should find out more > about the bean coding standard. > > Regards, > > George.
Java Virtual Machine source code
Hi, This is Fady Youssef, a student in the American University in Cairo... We are doing a project to extend the Java language to support real time systems. We need to have access to a java virtual machine source code to extend it according to our own real-time specification. It seems that we will use real-time linux as our platform, so we are looking for a JVM source code for linux... The only one I found was Kaffe but some groups were complaining that it lacks adequate documentation.. Do you have your own implementation of JVM? do yo offer the source code for non-profit usage? Thank you for your concern --Fady
Anyone tried JNI Interface via dlopen/dlsym methods? I SEGV with it.
Hi all, I'm having trouble loading the java libraries and accessing the JNI Interfaces using dlopen/dlsym/dlclose. This works fine on Solaris, but for some reason it fails on Linux. First I use dlopen to load libjava.so, then I use dlsym to get the addresses for the JNI Interfaces (JNI_GetDefaultJavaVMInitArgs, JNI_CreateJavaVM, JNI_GetCreatedJavaVMs) and call each as appropriate, but right after I load the library, I start getting "Tried to free bogus memory X, ignored" and after server hundred of these messages, I segv with s"tackbase=(nil), stackpointer=(nil) Full thread dump: NULL (TID:0xAddress,sys_thread_t:0xAddress, state:R) prio=5" . Any ideas? I'm not actually on the mailing list, so if you could reply directly to me as well as the list, I'd appreciate it. I downloaded the 1.1.7v1a native threads version of the JRE and it fails same way.

Sun's Commitment to Port JDK 1.2 to Linux
I was excited to hear about Sun's commitment to porting JDK 1.2 to Linux (see http://www.javasoft.com/pr/1998/11/pr981102-01.html) and as new subscriber to this list, I'd be interested in reading any thread discussions that have already taken place on this topic. I'm especiallly curious about when this is likely to happen, and how this changes anything for the Blackdown Java-Linux porting project, if it does at all. If this is an old thread, can anybody tell me how to request an archive from this list server? If not, anybody care to comment now?

Some weird security problems in netscape
Hi ! I am having some weird security problems with netscape 4.5 I have an applet that tries to fetch some data over the net. The data are located in the same host as the applet and under its codeBase. It is my conception, that the applet should download the data normally. But this is what I get: netscape.security.AppletSecurityException: security.class from local disk trying to access url: http://egnatia.ee.auth.gr/~dviz/dip/images/lena256.raw at netscape.security.AppletSecurity.checkURLConnect(AppletSecurity.java:944) at java.lang.SecurityManager.checkURLConnect(SecurityManager.java:1239) at netscape.net.URLConnection.connect(URLConnection.java:79) at netscape.net.URLConnection.getInputStream(URLConnection.java:198) at java.net.URL.openStream(URL.java:606) at dip.applets.DIPApplet._fetchImage(DIPApplet.java:131) at dip.applets.DIPApplet._loadImages(DIPApplet.java:121) at dip.applets.DIPApplet.init(DIPApplet.java:63) * at netscape.applet.DerivedAppletFrame$InitAppletEvent.dispatch(DerivedAppletFrame.java:553) at java.awt.EventDispatchThread$EventPump.dispatchEvents(EventDispatchThread.java:81) at java.awt.EventDispatchThread.run(EventDispatchThread.java:135) at netscape.applet.DerivedAppletFrame$AppletEventDispatchThread.run(DerivedAppletFrame.java:911) Has anybody got a clue about what this means and how I could work around it? -- Dimitrios Vyzovitis -- Information Processing Laboratory [EMAIL PROTECTED] -- Aristotle University of Thessaloniki [EMAIL PROTECTED] -- Dept. of Electrical and Computer Engineering http://egnatia.ee.auth.gr/~dviz
