OC4J and FDS

[ragulgul]

I installed Flex data services in Tomcat 5.5.1 and it worked
fine. But when I tried installing it in OC4J 10.1.3.1, the web app
samples would get deployed but the small applications like CRM,
FlexCab etc will not work. I got a "send error" (with HTTP error
code 500 - internal error) when I tried invoking these
applications.



Note that I have followed the instructions for OC4J at the
FDS install instructions page.



The errors that I got from the application logs in OC4J was
as follows:

06/08/22 11:14:54.343 10.1.3.0.0 Started

06/08/22 11:14:54.643 samples: Error initializing servlet

Can someone help me?

Hi,



OC4J testing was performed against version 10.1.3.0.0.



Can you confirm that you've done the following:

---------------------------------------------------------------

To run Flex Data Services 2 on Oracle Containers for J2EE
(OC4J), you must pass the -userThreads argument when starting OC4J.
For example, you can modify the CMDARGS line in the oc4j.cmd file,
as the following example shows:



set CMDARGS=-config "%SERVER_XML%" -userThreads





You may also want to check the OC4J docs to see if the
version you're running has a setting to allow 3rd party MBeans to
be registered without being blocked by the security manager.



Best,

Seth

Yes, I had already done the changes to oc4j.cmd as you had
posted. I will take a look at OC4J docs and will get back on this.
Thanks.

Workaround is to disable the security management for custom
MBeans that Oracle imposes in their latest release:



-Doc4j.jmx.security.proxy.off=true
