Re: [JBoss-user] JBoss and Java Web Start
Hi,
I think you need to set the option -Djavax.naming.initialcontext to the class
that implements the initialcontext (f.e. javax.naming.InitialContext). I'm not
sure I typed the right option name, so check the JNDI spec for this.
Do you like Web Start?

Re: [JBoss-user] Please clarify JBoss and Tomcat setup
Hi, for JBoss and Tomcat install you only need jboss-tomcat-2.1-beta.zip. Unzip the zip file. That's it. You're ready, it works. Try to deploy an EAR containing a WAR in the jboss21/deploy directory. Alternatively, you can modify the tomcat32/conf/serverl.xml and add a context pointing to a directory where you have a WAR or an unpacked web application. You always start jboss and the embedded tomcat using jboss21/bin/run.sh or run.bat (depending on your platform).
