What is the difference between a Constructor Method and a Method? Is it that Constructors are carried out on Local Variables and Methods are carried out on instance variables? What would you use if you have a local variable with an instance variable added from an external class? Are they the same code with 2 different names delineating 2 different uses?

Hi all, I have a webservice that connects to a sql express 2005 database. I use tableadapters to fill my dataset in the constructor of my webservice. My question is, when is this happening? Only when the webservice is started, or everytime a new user connects?

The java class Exception extends throwable which does not contain a null constructor. Due to this fact JAX-WS with Clientgen can't generate a working client. I have read that if using JAX-WS directly and a JBoss extension you can inject annotations in and make throwable a transient type, but I need to know if there is anyway to accomplish this using ...
