Apache Jboss and 500 Error

[gkrishna101]

Hi,

We have our application running on JBOSS 4.2.3 fronted by apache 2.2 webserver. I am using mod_jk connector now. We are having intermittent issues with one of the JBoss server returning 500 error.

Is there a way where the webserver can mark the app server down and not send request to that app server if it returns 500 error? Can mod_jk or mod_proxy do this?

Thanks

Hi Ganesh,

the best way to handle real 500 errors is to define an error-page in your web.xml

<error-page>

<error-code>500</error-code>

<location>/someerror.html</location>

</error-page>

Bit when your server is down, it results to a 503 error. Then you can add to your Apache config:

ErrorDocument 503 /service/server-down.html

Best regards,

Mark
