java - Eclipse keeps running my old web application

Question

OMG - what is going on with Eclipse (3.3 Europa) - has anyone come accross this problem (bearing in mind I have been messing about with uninstalling different Tomat containers and installing others - but anyway thats another story)

When I change a line of code or remove a class within my project - when I come to debug - it actually goes to a line that is commented out and runs that line regardless!!!! e.g.

//System.out.println("you should not be able to read this!");

UPDATE: This can be solved by setting Project -> Build Automatically (see answer below).

REMAINING PROBLEM:

Eclipse is not keeping my hot deploy folder current with the latest changes to my project:

I found out to my horror that some old remenants of my project are 'hanging around' in the folder that I think Eclipse uses for hot deploys or something

C:myJavaCode.metadata.pluginsorg.eclipse.wst.server.coremp0wtpwebappsmyWebApp

basically it is not actually copying accross any changes made in the classes of my working dir!?!??

...anyway - in order to keep my project up to date - I have to modify this folder too - TOTALLY UNACCEPTABLE - as you can't develop in this way - it would take you eons! Anyway, if anyone can help explain to me what stupid thing I have done to get me in this mess and how I can get out of this mess - I would really appreciate it.

Answer 1

Have a look at:

Windows>Preferences>Server>Launching...

and:

Project>Build Automatically

maybe you accidentally disabled the auto-deploy features.
