Changing HTTP Listener Port on Oracle Express 10g

The oracle installer does not give you the chance to change the port of the HTTP Listener. I installed my Oracle 10g Express Edition under Windows and my Tomcat Servlet Container already uses port 8080.

Oracle Database 10g Express Edition Release - Production

SQL> exec dbms_xdb.sethttpport(8081);

PL/SQL procedure successfully completed.

If you still would like to use the MyFaces implementation you have to add the following lines to your web.xml file:

Comparison of different Repository Managers

Deng Ching wrote a good blog entry about existing repository managers. Repository managers have become a big part in software development. Maven without a good organized and well structured repository would be useless. Besides Maven, repository managers can also be used by Ant or Ivy.
Please note that Deng Ching is a developer of Maven Archiva. So his comparison might be not as neutral as you might expect.
