How to execute java source in Eclipse

I have a java sourcetree with eclipse projects. When I originally created them, everything works fine. The problem is that I had to switch machine and could only copy the whole working source tree to the new machine. Now when I try to execute my projects in Eclipse it doesn't work, because Eclipse apparently doesn't accept a sourcefile as the main entry point.

The problem is as follows:

The package path looks like this: 

package a.b.c.d.project;

Now when I import the project via the New Project and specify the path, then it uses the path of the project which is on a lower level and I get an error that the package is wrong. When I import the whole sourcetree as a single project, the package path is correct, but then I can't launch the source. When I try to create a run configuration Eclipse claims it doesn't find any sources with main and the dialog box stays empty even though the sources are there and contain a main.

So what is the exact procedure to tell Eclipse to execute my Java files?

Update

An example from a source looks like this:

package net.arcor.sls.HibernateDB.helper.hibernate_database_record;
import ...
public class HibernateDatabaseRecord
...

and the error message is:

The declared package "net.arcor.sls.HibernateDB.helper.hibernate_database_record" does not match the expected package "helper.hibernate_database_record"

So apparently it now ignores that full package path because it set the projects directory as the package base. Since these projects were initially created as subprojects under the "net.arcor.sls" project I somehow need to reset the path.
