TL;DR The F5 BigPipe LTM uses HTTP/0.9 to send its HTTP monitoring requests by default. Wildfly 9.0 does not like this; moving to a monitor request of HTTP/1.1 fixed the problem. Caution: LTM 10.2.x and 11.x do not append a CR/LF to the end unless you are using Basic Authentication. This is contrary to previous …

rvm, despite being wonderful, doesn’t play very well with torquebox under cygwin. In particular, the gem paths are not working. So, in order to fix this, simply do: rvm use system And then it will work right. Once you’re done with the torquebox work, you can go back to using rvm.

Prior to JBoss 5, the jboss-all-client.jar was pretty much all you needed. However, the JBoss 5 Getting Started Guide states the following: The client/jbossall-client.jar library that used to bundle the majority of jboss client libraries, is now referencing them instead through the Class-Path manifest entry. This allows swapping included libraries (e.g. jboss-javaee.jar) without having to …

Torquebox and Cygwin don’t work as nicely together as one might hope. That said, here are a couple of findings: In order to deploy, you need to set the $JBOSS_HOME with the Windows path. You can do this via export JBOSS_PATH=cygpath -w PATH_TO_JBOSS. Additionally, the JRUBY_HOME needs to be a windows path as well. Otherwise …

jnp is a JBoss protocol which exposes jndi. It is, by default, bound to port 1099. I’d been using that port as a heartbeat, but “cheating” — I would open a socket and then close it immediately. However, this caused problems. jnp is chatty. And it got upset at my not letting it say ‘hi’ …

One, One database record! Two, Two database record! Muahahaha!

A coworker and I discovered an issue with jboss’ run.sh (which starts the app server). The problem lies in different flavours of unix (or unix-like) shells returning different values for wait. The relevant code is:
|
1 2 3 4 5 6 7 |
# Wait until the background process exits WAIT_STATUS=0 while [ "$WAIT_STATUS" -ne 127 ]; do JBOSS_STATUS=$WAIT_STATUS wait $JBOSS_PID 2>/dev/null WAIT_STATUS=$? done |
This is all well and good in linux — redhat uses /bin/bash and ubuntu uses /bin/dash for /bin/sh — …
