This is just a quick example showing how I have used a little groovy script (it doesn't need to be groovy) to quickly fix or transfer messages from one ActiveMQ queue to another. In the example below the script simple re-routes messages from one instance to another instance using Apache Camel. I have used this before to also fix errors in messages and re--process them before placing back on another or the same queue. It also can be used to quickly move failed messages from a failure queue to the live queue. Scripts like these are easier to use when the message contents are of a standard/open type, i.e. xml, json, raw text etc. This way you can easily parse, fix and modify message bodies without any complex logic or translation.
Also, subdomains are counted very powerful. I know many blogs take advantage of this while gaining backlinks.
