Apache mod_jk make A4J fail for cluster environment

garyyyding Dec 9, 2009 4:05 AM

I has a seam application, it work fine in the local jboss5.1

Bit it is not fine after apply Apache(2.2.14) and mok_jk(1.2.28). My application lost function. The root cause is the A4J not work.

I check the Apache' access.log file, it says

10.200.0.240 - - [09/Dec/2009:09:30:50 +0800] "GET /jboss-seam-jpa/a4j/g/3_2_2.SR1org/richfaces/renderkit/html/scripts/skinning.js HTTP/1.1" 404 1188

So I guess apache block A4J.

I do a test to prove
Apache server is 10.200.0.18:80
My jboss5.1 cluster node is 10.200.0.240:8080
I can download http://10.200.0.240:8080/jboss-seam-jpa/a4j/g/3_2_2.SR1org/richfaces/renderkit/html/scripts/skinning.js
Bit fail http://10.200.0.18/jboss-seam-jpa/a4j/g/3_2_2.SR1org/richfaces/renderkit/html/scripts/skinning.js

Please help me!

Thanks!

I find way, but I am not sure if it is right way.

Richface uses /seam/resource and /a4j for resource.The key point is to let Apache passby those url.

In the httpd.conf, for example

ProxyPass /jboss-seam-jpa/seam/resource/ http://10.200.0.240:8080/jboss-seam-jpa/seam/resource/
ProxyPass /jboss-seam-jpa/a4j/ http://10.200.0.240:8080/jboss-seam-jpa/a4j/

It means it dispatch to a server, for example http://10.200.0.240:8080. And those setting will not affect load balance.
