One of the developers on my Team came up to me with the folloing scenario, whilst deploying module a webapps to weblogic, one of them would not deploy due to an error "could not istantiate DataSource <datasource name>" ... altough this DataSource isn't declared in that specific app.

It could be I am pointing out the obvious, altough If I'm not the following should save you some time.

I am mentioning this for on a large Cluster like ours which consists fo several machines, build & deploy lifecycle can take over an hour-three depends on the environmens site & location (automation or not ...), so why spend valuable time on it ?

Scenario:

An article demonstrating a neat Java 6 SE feature: publishing a SOAP web service from a standalone application. This may be quite useful for prototyping, testing, building slim gateways that expose a WS on the outside and connect to an internal JVM process on the inside without the need for a full blown container. How can this be done? using the magical @WebService annotation and a call to Endpoint.publish(url, serviceObj). Ooops! I've ruined the surprise.
