JMS C API in Solaris SPARC

Question

Hi Mates ,
I am trying to use the JMS C API to invoke a JMS queue from a stand alone C code in SOLARIS SPARC 10 . The Weblogic version is 10.0 patch 2 .
I am not able to compile the program . I am using the following command to compile
CLASSPATH=/weblogic/bea/wlserver_10.0/server/lib/weblogic.jar
export CLASSPATH
LD_LIBRARY_PATH=/weblogic1/bea/wlserver_10.0/server/native/solaris/sparc:/usr/java/jre/lib/sparc/server/.
export LD_LIBRARY_PATH
cc -I/weblogic1/bea/wlserver_10.0/server/include -L/usr/lib -L/weblogic1/bea/wlserver_10.0/server/native/solaris/sparc -L/usr/java/jre/lib/sparc/server -ljmsc -ljvm -lpthread -o JMSClient JMSClient.c
I am getting the following error
Undefined first referenced
symbol in file
sched_yield /weblogic1/bea/wlserver_10.0/server/native/solaris/sparc/libjmsc.so
ld: fatal: Symbol referencing errors. No output written to JMSClient
What could be the issue .
Your help in this will be very useful to me .
Regards
Dinesh

Answer 1

It was caused by the 2nd threads' classloader.
          The 2nd thread uses the bootstrap classloader by default when attached to jvm, which loads the 'core' java classes only, not even extended classes.

          This cause JNDI factory initialization failed.

          The solution is to set the 2nd thread's context loader as the system class loader using JNI. See java.lang.Thread#setContextLoader and java.lang.ClassLoader#getSystemClassLoader.
