JIT API has not been well documented by Sun. `The JIT Compiler API' by Frank Yellin is the only document describing the JIT API of classic VM, although it is written for JDK 1.0.2(!) and not comprehensible. But we can see the source code of existing JIT compilers such as TYA, shuJIT and OpenJIT. They are helpful in understanding the JIT API and the JDK source code may be also helpful. And JIT developers on this list may answer if you have specific questions. Kazuyuki SHUDO Happy Hacking! Muraoka Lab., Grad.

Problem with JNI
Hi,
I've racked more brains than I've got trying to figure this out. If
someone can give me a hint as to how I can proceed with solving this problem,
I would be obliged. I'm invoking the JVM using dlopen to open the 1.2.2
libjvm.so and am doing a dlsym of the JNI init args and JNI CreateJavaVM
functions. The JVM initialises quite OK and proceeds into the Java Code up to a point.
But it refuses to enter within a method which is a simple method
where some variables are initialised. We thought the Java and Native stack
sizes or the heap size might be less and so we increased all that but it
doesn't help.
The relevent code is something like this.
Class Conn code segment:
Print.printl("About to create message");
Message message = new
Message( msgindex , request , props);
Class Message code segment:
Constructor: Message(int msgindex, Request
request, Properties props){
Print.printl("Creating message");
m_msgindex=msgindex; m_request =
request; m_properties=props; }
I'm getting the message " About to create message" in my status file but am
not getting the "Creating message" when I invoke the JVM from my native code.
However from the command line "java" I get both messages and the program
executes as desired. Also this happens only in Linux. In Solaris things work
fine. Also I'm using the native_threads version of the java library.
We suspect it to be a JVM tuning problem. Could anyone have tips on the parameters
to be passed for tuning. I'm awar that JVM provides the JDK1_1InitArgs tstructure to
pass parameters but changing the structure parameters desn't seem to help.
Any ideas would be welcome.
Thanks

Maybe it shows thousands of "zombie" TCP/IP > connections. The first thing that I thought of was open file descriptors. lsof doesn't show any zombies. I'm assuming that all the threads in a process share the same file descriptors, in which case my server is only using about 100 file descriptors. Just in case, I built a new kernel this morning with NR_TASKS, NR_OPEN, OPEN_MAX and __FD_SETSIZE all bumped up. It performs the same (actually a little worse). > Which JDBC driver are you using?

I've tested this with our own Oracle8i native (OCI) drivers and the Sybase jConnect type 4 drivers for both Adaptive Server Anywhere and Adaptive Server Enterprise. I've tried both local database servers and network based servers (on big hardware). Is there any kernel output I can enable so I can find out why it thinks it needs to reject incoming connections?

How do I trap Keycodes ?
Hi All, Could any one tell me how to trap Keyevents (Keyup, down etc.) with out displaying any GUI components? I noticed that the KeyEvents are delivered only when the GUI component is shown and focus is on that. I want to get Keycodes with out displaying any GUI component. My application does not require any GUI component. Any help would be appreciated. thanks and regards, syam -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
