Bean class not compliling

Question

In a jsp page, a method of bean class is being called as.... <% beanId.BeanClassMethod( ); %> The problem with my program is that my bean class is not compiling. This bean method uses some "outside" classes which are in a single jar file. I have included that jar file in my classpath. The jar file includes classes in different paths like
a/b/c/x.class
a/b/d/y.class
a/b/e/z.class
Now what I want to know is whether I need to import these classes in my bean class and if yes how? I did import them as below:
import a.b.c.*;
but the compiler gives error as:
package a/b/c does not exists.
Can anyone figure where am I going wrong?

Answer 1

Follow the following steps and your problem will be sorted -
1. Find out if the mentioned class files are present in this jar file
Move to the directory where this jar file is placed.
Like, if your jar file is located in C:/myFiles/myjar.jar , move to
C:/myFiles > jar tf myjar.jar
when you execute this command, you will see the contents of this jar file as -
a\b\c\x.class
a\b\d\y.class
a\b\e\z.class
This ensures that required class files are located in this jar file.
If you could not see the required class files, you have caught the problem.
2. Ensure the directory hierarchy represents the package
First of all the set the class path to include the current directory in the classpath as-
C:/myFiles > set CLASSPATH=%CLASSPATH%;.
This appends dot(.) to the class path and this . represents the current directory.
Use the following command -
C:/myFiles > javap a.b.c.x
If you get the message like -
Class 'a.b.c.x' not found
it infers that this class doesnot have a package statement in it or the package statement doenot reflect the said directory hierarchy.
If you see the list of methods it means that everything is fine and the only problem is that directory n which this jar file is locate is not in classpath
Similarly check these other classes
C:/myFiles > javap a.b.d.y
C:/myFiles > javap a.b.e.z
Hope this helps
