install_jar problems

I am not sure if this is the right forum for this message...but here goes..

We are moving one of our servers to Red Hat Enterprise Level 3.

We are running IDS 9.40.UC2 in a test environment on that server.
One of the areas we are looking to expand into is the usage of
"Java in a server" for some UDR's that we are looking to include in
applications for that machine.

The problem is that I cannot register/load (not sure of terminology) my
jar files into the database.

An example of the error I receive is :

execute procedure install_jar(
"file:/opt/informix/940/extend/krakatoa/examples/Env.jar", "env_jar", 0);
9431: Can't find system class or method or library /opt/informix/940/extend/krakatoa/jre/lib/i386/libjava.so).

This was taken from an attempt to run the examples in the krakatoa folders.
It is the same message when we attempt to run our own "test" jar files into the database.

These are relevant lines from the ONCONFIG file

SBSPACENAME sbsp1 # Default smartblob space name - this is where blobs
# go if no sbspace is specified when the smartblob is
# created. It is also used by some datablades as
# the location to put their smartblobs.
SYSSBSPACENAME sbsp1 # Default smartblob space for use by the Informix
# Server. This is used primarily for Informix Server
# system statistics collection.

JVPCLASSPATH /opt/informix/940/extend/krakatoa/krakatoa_g.jar:/opt/informix/940/extend/krakatoa/jdbc_g.jar

The CLASSPATH is as follows :

$CLASSPATH
.:/opt/informix/940/extend/krakatoa/krakatoa.jar:/opt/informix/940/extend/krakatoa/jdbc.jar:/opt/informix/940/extend/krakatoa/ifxlang.jar:/opt/informix/jdbc_2_21/lib/ifxjdbc.jar:/opt/informix/jdbc_2_21/lib/ifxsqlj.jar:/opt/informix/jdbc_2_21/lib/ifxlang.jar:/opt/informix/jdbc_2_21/lib/ifxtools.jar:


As a further piece of information (it may or may not have any bearing),
if I try to run the demo script (runjdbcdemo.sh) from the jdbc_2_21 package,
it is successful with the following variables in place

JAVAHOME=/usr/java/j2sdk1.4.2_01/jre
JDBCHOME=/opt/informix/jdbc_2_21


When the JAVAHOME variable is changed, I get the error message below :

JAVAHOME=/opt/informix/940/extend/krakatoa/jre
JDBCHOME=/opt/informix/jdbc_2_21

JDBC Version : Error occurred during initialization of VM Unable to load
native library: /opt/informix/940/extend/krakatoa/jre/lib/i386/libjava.so:
symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

It appears similar to the error above.

As a further note, I have made the changes for JRE Shared Libraries as per
the ids_machine_notes_940.txt file, and have run ldconfig as root.


Any assistance from the forum would be appreciated.

Thankyou
