Remove a workspace in Eclipse

The following will remove it from the dropdown list when your startup Eclipse. Eclipse is not very happy if it thinks there's supposed to be a workspace but it's not there.

Window,Preferences,General,"Startup and Shutdown",Workspaces

From there you can delete a workspace you are no longer using, and then delete if from your drive

What is Nexus?

-----Original Message-----

Subject: Re: Nexus

Nexus is the shared Maven artifact repository. It's basically a cache for jars so that if your maven downloads apache-common-1.3.jar, Eric's maven won't have to go on the web to download the same jar. All developer VMs and Hudson are configured to get jars (called artifacts in maven terms) from Nexus by default.

The url for our Nexus instance is http://halsvn01:8081/nexus

The website for nexus can be found here : http://www.sonatype.org/nexus/

Copying static content to VM’s

First you need to copy static content from here:
cp -R /wbi/haldata/webdev/* /home/jboss1/HAL/

And then supplement it from your workspace:

On developer VM, to copy static content from the checked out halwebsite folder to the apache document root and compile at the same time, you can run the following command from the root of your checked out project:

cp -R halwebsite/* /home/jboss1/HAL/halwebsite/ && mvn install

The && shell operator is a logic AND, it means that the 'mvn install' command only runs if the left part of the commands succeeds.

Deploy static content and deploy in JBoss (using hot deploy):

mvn install && cp hal-ear/target/hal-*.ear /home/jboss1/programs/jboss-eap-5.1/jbossas/server/haldev-vm-template/deploy/ && cp -R halwebsite/* /home/jboss1/HAL/halwebsite/
