OC4J problem

[Corey]

Hi guys,
I deployed roller on OC4J 10.1.3(standalone) instead of Tomcat, and it's
weird that all of static
content such as css, image(gif, png) and ,javascript can not be accessed.
The access-log got some infomation like "GET /roller/images/xxx.gif 500
error".
How can I fix this problem?
