Well, I tried running TomCat on its own. There are several issues,
1. JNDI namespace integration
This can be accomplished even in a stand-alone TomCat by properly
rewriting JbossWebXmlReader RequestInterceptor so that it contacts the
NameServer running on Computer1 and gets its InitialContext from
there. I've tried that and it did not fully for me, perhaps, my
implementation was flawed.
2. Accessing DataSources
This is a JDBC issue. I was trying to split an EAR, so that it's
WAR component sits on one machine and EJBs on another. But I did not want
to do too many modifications to the source of the application (in fact,
none, except for minor deployment xml mods). The WAR I was using needs to
access DataSources (i.e. the database) so they have to be pre-configured.
It is impossible to access DataSource objects sitting on Computer1 from
Computer2 because those are VM-local (they sit in java:comp/env JNDI
context for that reason). So, I need to configure DataSources on
Computer2. The simplest way I was able to do it, is to start TomCat as
part of JBoss with DataSource setup in jboss.jcml
