I am getting some odd behaviour with the loading of classes since marc's RH
changes and after spending a couple of days testing things out and trying to
convince myself I'm not going mad I've nearly given up trying to figure out
whats going on.
I basically want to know if anyone else is getting any of these (seemingly
unrelated) problems and and/or whether anyone else knows if I am just plain
doing things wrong. None of these problems occur with pre-RH JBoss 2.5.
1) The DefaultDS DataSource throws an SQLException "No suitable driver" when
I try to get a connection even though it seems to initialise correctly and
the jdbcProvider successfully loaded the org.hsql.jdbcDriver.
Snippets from log...
[JdbcProvider,INFO] Initializing
[JdbcProvider,INFO] Loaded JDBC-driver:org.hsql.jdbcDriver
[JdbcProvider,INFO] Initialized
followed by...
[DefaultDS,INFO] Starting
[DefaultDS,INFO] Started
and finally...
[JDBCManagedConnectionFactory-1,ERROR] Unable to create ManagedConnection:

2) Originally Jetty failed every time it tried to compile a jsp page because
it can't find the javax.servlet.* classes, even though I had them in the
lib/ext directory (in javax.servlet.jar) along with everything else. Then I
added the javax.servlet.jar as a standard extension to my jdk and now it
can't find some of the jasper classes, although it finds others. The error
message below comes from a jasper class because it can't find another jasper
class, even though they are both in the same jar file! Jetty also serves
servlets fine.
