Error while using .jar file instead of class file.

Question

Hello friends,
I created a java class which are referred and called from other jsp\xml and java files. I compiled this java class and everything is working properly. However, I do not want to use class files but want to use jar files instead. So, I created a jar file of this class file by using the command "jar -cvf jarfilename.jar".I kept the jar file in its respective folder .Also, I removed the class file from its path, just to see that the jar file will work automatically.
Unfortunately, I am getting an error:
java.lang.RuntimeException: Component.createComponent(...) Component class not found: <java class path>. I also tried giving the path of this jar file in the classpath. This also does not seem working.
How to solve this problem?
Thanks,

Answer 1

You probably populated the jar file incorrectly.
A common mistake is to include the path that you had on the classpath, in the jar file.
So a person will have a classpath like this: /foo/
And a class in a package bar, like this:
package bar;So that other classes would include the file like this:
import bar.TheClass;And the class file is on the filesystem like this:
.../foo/bar/TheClass.classThen they'll create the jar file including the foo directory, so if they list the jar's contents, they'll see the above (/foo/bar/TheClass.class). But this is wrong. It should start off so that the jar entries start with the top-level package names (like /bar/TheClass.class).
Maybe you've done that.
