[I had already posted this message in comp.lang.java.prog. But didn't get any response.] I have a tomcat service, which manages a process (for which the native binaries are available and the platform is Linux). This process in turn uses the JNI to make calls to java programs. The jvm library (to be used for the creating a JVM) is specified explicitly within the native code. In this scenario, the creation of JVM from native code succeeds only when client JVM lib is used. When server JVM lib is used, the process crashes (stack trace is pasted at the end) Somehow, if I modify the jvm.cfg (the config file present in <JAVA_HOME>/jre/lib/i386/jvm.cfg where the various JVM configurations are specified), such that server JVM configuration is on top above client JVM configuration (by default, its client JVM config which is at the top in the config file), the creation of JVM succeeds for server JVM lib. Will the config file even matter when we explicitly specify the JVM library to be used? What could be the problem? Srihari.
