Bill,
you are looking at java: which for jboss is a thread local environment (ie
you won't see it in tomcat).
I can't remember where we put the datasources under jndi, all I know is that
they are under "global" names, the jndi stuff is for beans only.
Sorry I can't be of more help, i did go in the source but couldn't find the
place where we give the name to the sources (does anyone remember?), also
they are not supposed to be looked up directly but in your case it is a work
around (is it system/jdbc/<name>)....
regards
marc

|
|
|OK, I'll take one more stab at explaining what I am trying to do and
|hopefully clear things up so I can get this working:
|
|I have written an application for Tomcat 3.2. I used Minerva for pooling
|jdbc connections with an eye towards integrating with jBoss. I am
|trying to
|do that now. I have several servlets and jsps that depend on getting a
|connection from a Minerva based connection cache. I have encapsulated the
|code to get the connection cache into a single class.
|
|As far as I know, I am running the full inVM integration (what indicated
|that I wasn't?). With patched Tomcat 3.2? I downloaded it just a few days
|ago (binary). I stepped through jBoss online docs for running Tomcat inVM
|and I can attach to the main page of my Tomcat app which doesn't require db
|access.
|
|Now I tried running my code as is, but it bombed becuase I could
|not include
|the jBoss jar (in support of my encapsulated class calling Minerva) as I do
|when I run Tomcat standalone (jBoss complained when I tried to).
|
|Ricard pointed out that I should do a jndi lookup to get at the connection
|cache. I rewrote my class to do so and, as I pointed out in my last post,
|this fails with an error indicating that the "comp" is not bound. Please
|note that I do have jBoss setup for connection caching of my db
|(or so jBoss
|indicates when it starts up).
|
|My requirement seems very simple. I need access to a cached db connection.
|I had it with Tomcat/Minerva. I don't have it with Tomcat/jBoss/Minerva.
|My preference is to use the connection cache as configured under jBoss, but
|at this point, I'd just like to get my app working.
|
|Anybody?
|
|Thanks to all for the help,
|
|
