Good morning FILIPPOS!

Your last email put up the light!  I don't quite understand how
applications run under Tomcat containers.

When DSpace is compiled and deployed.  We are instructed to copy contents
under /dspace/webapps to Tomcat's webapps, and I also did that...

I think I still confuse how these modules are called.  In the
/dspace/bin/dspace script, it seems that /dspace/webapps/oai/... is used.
This morning I copy the XOAI.class to that location and did the oai import
again.  This time it worked just fine!  No single error.

Anyway, when oai is called via the browser, I think (in mycase)
/opt/tomcat/webapps/oai will be called.  So it is better to create symbolic
links instead of copy all the contents.

Thanks a lot for your helps.

Panyarak
