Re: Looking for simple servlet-to-javaspace example

Hi Patrick,

Regarding JBoss;
If you change the following in the 
jbossweb-tomcat55.sar/META-INF/jboss-service.xml 
      <attribute name="UseJBossWebLoader">false</attribute>

to 
      <attribute name="UseJBossWebLoader">true</attribute>

Discovery should work as with regular applications. 
Add this to JBOSS_HOME\bin\run.sh 
    JAVA_OPT=$JAVA_OPT -Djava.rmi.server.codebase = 
http://host-name:port/<service-dl.jars> 
-Djava.security.policy=<pathTo>/policy.all

HTH


Vriendelijke groeten / Kind regards / Meilleures salutations / Saludos

Fair enough. I am looking from the Tomcat/JBoss side of things as well
to see how they work. I see how to grant permissions to a specific
servlet(s) via the codebase file URL for its webapp installed in
Tomcat.

e.g.

grabt codeBase
"file:${catalina.home}/webapps/some_app/WEB-INF/classes/-" {
   stuff
}

On this "container" side of things I think I just need to understand
whether/how Tomcat and/or JBoss support setting these things
individually without bouncing everything. I assume they do, but I just
have to be patient and learn one thing at a time.

Alright. This is getting to what I think I'm looking for. As you said
I can go with AllPermission for now and figure this stuff out more
specifically.

OK. I think I can understand this a bit later too.

Thanks, this puts some more pieces together for me. 

By the end of this with some help I should have the
example-in-one-place I was hoping for. At least some more lore may be
captured on an email list for future reference! 8^)
