Subject "Unable to download the artifact from any repository" running "camel-example-loan-broker"
Date Thu, 28 Aug 2008 10:05:05 GMT

Hello,
I'm really new to activemq and camel, so I'm trying to follow examples as
much as possible, but I'm stuck on "camel-example-loan-broker" example.

I've installed activemq 5.1.0 and started it up:

# ps -af | grep activemq
root     27436 18654  0 11:57 pts/1    00:00:00 grep activemq

Then I downloaded camel 1.4 to have examples/ directory and try to play with
them a bit.

Untarred into /usr/local (and doing the same for maven 2.0.9) and then set
some variables like:

export JAVA_HOME=/opt/geps/jdk1.5.0_14/
export ACTIVEMQ_HOME=/usr/local/apache-activemq-5.1.0/
export http_proxy=http://<host>:<port>
export M2_HOME=/usr/local/apache-maven-2.0.9/
export M2=$M2_HOME/bin
export PATH=$M2:$PATH

I went into examples/camel-example-loan-broker dir and executed (as reported
in the README.txt file):

# mvn -X compile

Is this because I'm behind a proxy? what could be the problem here?

Thanks a lot in advance for your help,
