Application Server HTTP 404 problem

Hi SOA lovers

Writing blog after a long gap, this time with new flavors.

INTRODUCTION:
Sometimes when you navigate to the Enterprise Manager’s Application Server Control you will hit a 404 "Page not found exception".

REASON:
The most probable reason is that Application Server Control has no routing relationship defined with the Oracle HTTP Server by default.

SOLUTION:
To establish this relationship you have to set the ohs-routing attribute to true (default value in the file will be false) in the default-web-site.xml file at SOA server location: <SOA home>/j2ee/home/config. Make sure to make the changes always in the home container.

Make the changes as follws in the file:
<web-app application="ascontrol" name="ascontrol" load-on-startup="true" root="/em" ohs-routing="true" />

Now restart the SOA Server and try it. It should work.

If this solution doesn't work, follow my latest finding, posted on 22nd December 2009.
