Re: Java problem

[Rengasamy, Samy]

I copied your code for testing and I did get the message:
>> JVM started okay ...

I am using blackdown's JDK1.2.2.

I used the following commands to compile and run your program though:

$ gcc -c -o jvm.o -I/usr/local/jdk1.2.2/include
-I/usr/local/jdk1.2.2/include/linux jvm.c

$ gcc -o jvm jvm.o -L/usr/local/jdk1.2.2/jre/lib/s390/classic -ljvm
-L/usr/local/jdk1.2.2/jre/lib/s390/native_threads -lhpi

$ export
LD_LIBRARY_PATH=/usr/local/jdk1.2.2/jre/lib/s390/classic:/usr/local/jdk1.2.2
/jre/lib/s390/native_threads:/usr/local/jdk1.2.2/jre/lib/s390

$./jvm

Hope this gives you some info on what you are looking for.

Thanks,

Samy Rengasamy.

Subject: Java problem


/*
We have been unable to instantiate a JVM via a "c" program running
on Suse Linux V7.0 with JDK1.3.0. Below is a sample "c" program to
instantiate the JVM. When the program runs, the following messages
are display:

>> Creating JVM
Cannot obtain system-specific information
>> JVM creation failed rc=-1

Has anyone seen the message "Cannot obtain system-specific information",
and knows what it means???

Below was how the program was compiled and linked and executed:

cc -c -o jvm.o -I/usr/lib/java/include jvm.c
cc -o jvm jvm.o -L/usr/lib/java/jre/bin/classic -ljvm
export LD_LIBRARY_PATH=/usr/lib/java/jre/bin/classic
./jvm

Thanks for any help!!!!
