A question on setting CLASSPATH on linux

[rick collette]

Hi,
I have a jar file in the following subdirectory on my home directory:
app/application.jar
In order to run application jar in any directory,
I have to set classpath, right? How can I set
appropriate class on linux to all me to run
it directly, for example, from my home directory
like this?
[home]$ java -jar application.jar
I am not familiar with this on Linux, any help appreciated.

I don't think you need to set the classpath for this. Why not just use the full path to the jarfile?
java -jar /home/myname/app/application.jar

Thanks. The trouble is the data file has to sit
on the same directory as application.jar, the access to it will be refused if I do not execute the application from subdirectory app. I try to
set classpath like this:
export CLASSPATH=/home/myname/app/application.jar
the I use the following command to execute it:
java -jar -classpath application.jar
It did not work, I ma not sure if I did not set
the right classpath, or my command was not right.
Any ideas?

although you are exporting CLASSPATH but you are not setting it for java runtime.
Try this
java -jar -classpath $CLASSPATH application.jar

I still think the problem is not with the classpath. Try putting the following into a file "myapp", somewhere which is in the regular execution path:

#!/bin/sh
cd /home/myname/app
java -jar application.jar

then make it executable:

chmod a+x myapp

Now you should be able to run your application, data and all, by typing "myapp" from anywhere.
