Class loaded successfully but still not found

Question

Hi
I am facing a problem in instatntiating a class inside the oracle jvm. My
java class "SimpleQueueSender" has a function named "prashant" which I am
calling from PL/SQL using the following wrapper
create or replace procedure pr_invoke
as
language java
name 'SimpleQueueSender.prashant()' ;
This function "prashant" internally uses a class
"com/sun/jndi/fscontext/RefFSContextFactory" which is there in
fscontext.jar. I have loaded my class "SimpleQueueSender" as well as
"fscontext.jar" using loadjava into the oracle database. Following excerpts
show that the class "com/sun/jndi/fscontext/RefFSContextFactory" has been
loaded into the oracle database and is valid also
SQL> select object_name, dbms_java.longname(object_name) long_name,status
from user_objects where object_name like '%RefFSContextFactory' ;
OBJECT_NAME LONG_NAME
STATUS
/e9b75f22_RefFSContextFactory
com/sun/jndi/fscontext/RefFSContextFactory VALID
but when I try to invoke my class then it shows that the class
"com/sun/jndi/fscontext/RefFSContextFactory" not found....
SQL> set serverout on
SQL> exec dbms_java.set_output(10000) ;
PL/SQL procedure successfully completed.
SQL> set linesize 100
SQL> exec pr_invoke
Queue name is TEST_Q
Could not create JNDI API context: javax.naming.NoInitialContextException:
Cannot instantiate class:
com.sun.jndi.fscontext.RefFSContextFactory [Root exception is
java.lang.ClassNotFoundException:
com/sun/jndi/fscontext/RefFSContextFactory]
BEGIN pr_temp; END;
ERROR at line 1:
ORA-29515: exit called from Java code with status 1
ORA-06512: at "PRASHANT.PR_TEMP", line 0
ORA-06512: at line 1
Can somebody please help me with this.
Thanks

Hi Prashant,
It's been a few days since you posted, and have not yet received
any replies, so with your permission, I'll make a wild guess.
Perhaps one of the class that "RefFSContextFactory" depends on
(in order to instantiate it) is invalid? Remember, sometimes the
error messages don't really point to the cause of the problem,
so I suggest looking elsewhere.
By the way, have you tried running your java code outside of the
database -- to make sure the problem is not in your code?
Good Luck,
Avi.
