How can I use the created jar file for my other program?

**cchan2** · 02-25-2012, 08:37 AM

I have a java program 'A' that will use the other 8 classes (my classes) to run. Java program 'B' will also use the other 8 classes to run. Java program A and B are different main class but both use the other 8 classes.

I tried to create the jar file, add the jar files to classpath. Modify program A to add import jdbc.base.*; However, i am getting compile error below. I checked my jar files and all those 8 classes are there. What did i do wrong?

C:\Documents and Settings\chanck\Desktop\Myjava\Myjava.java:25: error: cannot access MySettings
MySettings my = new MySettings();
^
bad class file: C:\Program Files\ibm\SQLLIB\java\jccJar.jar(jdbc/base/MySettings.class)
class file contains wrong class: MySettings
Please remove or make sure it appears in the correct subdirectory of the classpath.

The message says that the MySettings.class file is bad.
Can you recreate that file?

What program generates the error message that you posted?

My program B can't able to use my jar file. Program A can, but not program B.

My program B can't able to use my jar file. Program A can, but not program B.

Please explain. What do you mean by "to use"? What is in the jar file? Do you create it? how do you create it?
