[jboss-user] [JBoss Seam] - ajax4js and seam integration - my guide

[Holger Prause]

Hello,

after spending 3 days with trying to integrate ajax framworks with jboss seam i finally get a integration with ajax4jsf working

1) first download ajax4js https://ajax4jsf.dev.java.net/nonav/ajax/ajax-jsf/

2) copy the following jars to  $JBOSSSERVERHOME/default/lib

el-api.jar
el-ri.jar
jsf-facelets.jar
ajax4jsf.jar
oscache-2.2.jar

this has to be done becourse of a global JBoss Classloader Issue (cant find the the posting i found for that, i am sorry) , when i deployed these jars with my application i got a lot of problems, well u can try out maybe u get it working.

Also make sure sure the jars mentionend above are not deployed with your application!

3)

change web.xml to and make sure no application view handler is defined.

  | <!DOCTYPE faces-config 
  |     PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"

change faces-config.xml to

4) if u have a have any h:commandLink with parameters (f:param)
   replace them with a4j:commandLink or the parameter will get lost

It works good for me even conversations seems (what a wordplay) to work.

Thats it, well its only a temporary guide until maybe some of the jboss crew can give a more detailed and better solution, hopefully its integrated in the next release :-)  (copying the jars in the servers /default/lib directory really gives me a bad taste)

Hope i could help someone,

Bye,

Holger
