Specify classpath when run class in jar file

[Bruce Jin]

I have application packaged in jar file and I run my class using:

> java �jar myjar.jar

How do I specify a additional classpath at run time? This command would not work:

> java �cp myclasspath �jar myjar.jar

[Rachel Swailes]

I use a classpath as follows...

java -classpath c:\mypath\myjar.jar myPackage.myClassFile

(where myClassFile has the main method)

Does that help you out?
Cheers,
Rachel

Thanks.
In my case the class is in jar file and the classpath would not work. One can put the "Class-path: xxx" in the manifest but I am wondering if there is a way to specify it at run time.

It doesn't sound promising.

Clip from
java tools documentation

-jar
...
When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored.

untestet:

java -classpath ./myjar.jar:/opt/oracle/ojdbc14.jar myPackage.myClassFile

(without the -jar option, and explicitly setting the Main-Class.)
