Question

Hi All,
I am new in javabean.I am trying to create a code
"Create a user-defined JavaBean having a label.Allow a user to change the caption of the user-defined javabean"
Problem where I face:
When I load the jar file for user-defined JavaBean in the BDK environment
I perform this:
1). Select the File->LoadJar command in the BeanBox window.This displays the Load Beans from JAR File dialog box.
2).select jar file and click the Open button.
But after this, selected JAR file should be loaded in the ToolBox window.But It could not happen and error message appear.
Error:: either jar file is corrupted or blank
But really It is not.
Pl help.

Should I create a folder name META-INF then inside this folder I should save manifest file with .mf extention as LP.mf ?????????????????????????????
After this still I face that problem.

Jar file D:\beans\beanbox\LP.jar didn't have any beans!
Each jar file needs to contain a manifest file describing which entries are
beans.  You can should provide a suitable manifest when you create the jar.
