i had been using jdk 1.3 with WSAD 5.1.2 Integration version. i used a ant build script to generate build files, where in the build script does some house keeping job by deleting the class files and so forth. the build output is prefect, however my workspace with class files in WEBINF\classes folder is empted! i am surprised by the way it happened. i tried to set the project properties and did a Rebuild so many times still have the same problem. can any one suggest why this happens and how to solve this ?
