    I Have 1 Problem Regarding Jar Files.. Ie

    1.) I Created a Project Name " Second "
    2.) Created A Package Name "UsingPackages"
    3.) In That Package I Created A New Class Name As "SecondClass"

    I Have Written A Method "Add " In That Class;

    And I Exported That One to a Jar File Name As " Second.jar"


    OK Then

    1.) Created Another Project Name "UsingPackage"
    2.) Added The Jar into This Project
    3.) I Called that Add Function in This It Works Perfectly...

    If both projects are in the same workspace, you shouldn't have to rely on exporting the jar (which necessitate an export after every update), rather in the build path add the project under the project tab (as opposed to an external jar library)

    Read my post above, which contains the solution: don't have your project depend upon a jar at all, but upon the other project.

    What I suggested allows you to develop the two projects in parallel, which is what it seems like you are doing (otherwise for what you ask you will need to rejar every time a change is made so your other project can access those changes). When you deploy to the user, you jar up both projects.

    In eclipse, right click the project that depends upon the other project, go to Properties. Select 'Java Build Path' and click on the Projects tab. Click "add" then select the project you wish to add to the classpath. Now that project is on the classpath - no need to jar it until you deploy. If the need be, remove the old jar from the jar dependency. That's about as explicit as I can get on how to accomplish what you want.
