I'm trying to compile a group of about 180 java programs. This are
independent. The problem I have is that the complier cannot find some of
the include modules nor can it find modules in the same folder. Any ideas?

It would be a good idea to explain what you have tried doing and precisely
what is going wrong (e.g. what error messages are you getting). Without
knowing that, it will be very difficult for anyone to figure out what is
wrong. And since Java does not have anything known as a "module", please
explain what you mean by that.

I have solved most of the problems. I wasusing the term module to be the
the include files. Most of the problems were due to not setting up the
libraries properly.

I have three errors, all due to the same problem. The library that is used
is:
cewolf.jar]/de/laures/cewolf

This is a required library for the project.

The imports are for both files are:

import de.laures.cewolf.CewolfDatasetProducer;
import de.laures.cewold.DatasetProduceException;

The first file
public class PieChartDatasetProducer extends CewolfDatasetProducer

The error for this is "cannot access DatasetProduceException"


The second file :

public class CategoryDatasetProducer extends CewolfDatasetProducer

the error occurs when method defined

public object produceDataset() throws DatasetProduceException

the two errors are identical:
"cannot override produceDataset; overriden method does not throw
de.laures.cewolf.DatasetProduceException"

The class file CewolfDatasetProducer.class shows up in the package to which
both files belong, but the file DatasetProduceException.class does not.

There is no way of including files in Java. Perhaps you are thinking of
"importing". The things that you import are called "classes".

Quote:

public class PieChartDatasetProducer extends CewolfDatasetProducer

The error for this is "cannot access DatasetProduceException"

I am not sure what would be giving you this error. It may be a problem
with the JAR file. How was the JAR file created?

In any case, it would help if you would show the complete error message,
along with the actual code that the error message points to.

"cannot override produceDataset; overriden method does not throw
de.laures.cewolf.DatasetProduceException"

This indicates that you are overriding a method, and that the overriding
method throws an exception that the overridden method does not. That is
not valid in Java.
