I have a problem in exporting my eclipse java project (class files) to a jar file. In the project, I have used some external jar files which are included through Project Properties' BuildPath configuration settings.

When I do the jar exporting, external jars' classpaths are not included MF file. But it creates an XML file (.classpath) which list all the external jar's classpath. When I run the jar file (created from the project export), it throws exceptions saying NoClassDefinition exception of an external jar.

How can I solve this problem, any idea? Thanks in advance.
