My favorite exception message

["Leonardo K. Shikida" <sh...@gmail.com>]

my favorite activeMQ error message :-)

java.lang.ClassCastException:
org.apache.activemq.command.ActiveMQObjectMessage incompatible with
org.apache.activemq.command.ActiveMQObjectMessage

how could they be compatible?

Running tomee inside eclipse "should" work exactly the same as outside
eclipse but you may need the right plugins depending on how you build
things.  First thing would be to check which jar files eclipse WTP is
publishing to the WEB-INF/lib folder in
.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\<your web
app>\WEB-INF\lib.  If the active mq lib is in there, then something is not
quite right with how eclipse wtp or your build is setup.

In the past i had issues when using maven to build my project with some
'provided' scoped jar files appearing in the WEB-INF/lib folder which were
resolved when i installed the m2e-wtp plugin.  Just mentioning that in case
you have a similar issue.  I now use eclipse with tomee everyday and WTP is
creating identical war files now to what a mvn clean install does, so i
completely trust it. m2e and m2e-wtp has improved massively over the past 18
months. 

Cheers,

Anthony

oh, but that's the nice part. It's not (of course it is, but I can't see it
where yet) :-)

that's probably because I am running tomEE from inside eclipse, and its
configuration is messing the class loading process

and adding to this, I was serializing the messages before to JSON, so my
code was using

Enumeration<ActiveMQTextMessage> e = browser.getEnumeration();

instead of

Enumeration<ActiveMQObjectMessage> e = browser.getEnumeration();

and guess what. It was working ;-) [comparing strings seems to be safer
than comparing objects...]

this is some sort of funny, I guess ;-)
