Receiving error on Unix server-- java.lang.UnsatisfiedLinkError: registerNatives
Hi all,
This is my first shell script, so I'm hoping the problem is that I'm just missing something, and not something bigger. I have a Java application that I wrote in WSAD that reads data from an Excel file and inserts values into a DB2 database. I'm able to run it successfully in WSAD. I am trying to write a Bourne shell script to call the main method so that I can have a cron job that runs the app at a specific time. It seems to be failing once I add the rt.jar in the classpath. Thanks in advance for looking.
This is my script:
#!/bin/sh
cd /usr/local/xmlMQ2smtp2
JAVA_COMPILER=off
export JAVA_COMPILER
JAVA_HOME= /usr/jdk_base
CLASSPATH=.
CLASSPATH=$CLASSPATH:migrationApplication.jar

LEARN ABOUT DEBIAN
jh_manifest
JH_MANIFEST(1) Javahelper JH_MANIFEST(1)
NAME
jh_manifest - Adds or/and modifies manifests for jars
SYNOPSIS
jh_manifest [debhelperoptions] [options] jar1 ... jarN
jh_manifest [debhelperoptions] [options]
DESCRIPTION
Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar files, it will only process these jar
files. Otherwise it will update all jar files in the packages it acts on.
When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar files.
FILES
debian/package.manifest (or debian/manifest)
This file consist of a list of jar files and values to add to their manifests. Values in this file will take precedence over values in
the original manifest (and command line arguments over values in this file).
It is allowed to list a link in this file instead of an actual jar file, provided that the link can be resolved when jh_manifest
processes it.
If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the jar file has been excluded.
As of javahelper >= 0.32, you may add comments in this file. If the line starts with a "#" it is completely ignored.
This file is ignored if jh_manifest is passed jar files via command line.
OPTIONS
-c classpath, --classpath=classpath
Sets the Class-Path attribute of all processed jar files to classpath.
If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have a Class-Path attribute.
-m class, --main=class
Sets the Main-Class attribute to class in all processed jar files.
-o options, --javaopts=options
Sets the Debian-Java-Parameters to options in all processed jar files. This attribute is used by jarwrapper to start java with extra
options (e.g. to make more memory available).
-j /path/to/java/home, --java-home=/path/to/java/home
Sets the Debian-Java-Home attribute to /path/to/java/home in all processed jars. This attribute is used by jarwrapper to determine
which JVM to use.
EXAMPLES
An example debian/manifest file:
# use the symlink so we do not have to update with the next upstream release.
usr/share/java/my.jar:
Class-Path: dep1.jar dep2.jar
Main-Class: some.awesome.Class
usr/share/java/dep2.jar:
Class-Path: dep1.jar
SEE ALSO
debhelper(7)
This program is a part of javahelper and uses debhelper as backend. There are also tutorials in /usr/share/doc/javahelper.
