Package <blah> does not exist error - NetBeans 6.8 & Windows 7

Question

I'm using NetBeans 6.8 on Windows 7. I upgraded from WinXP and NetBeans 6.7. Now my existing java web app project is no longer able to import/find the packages I've developed - I receive a 'Package ,blah. does not exist' and yet the packages do exist, worked fine in NetBeans 6.7 and the project still compiles and runs OK.

I've tried changing the Java Platform/JDK from 1.6.0_10 back to JDK 1.5.0_22 but I still receive errors package does not exist.

All other 'standard' libraries and packages are able to be imported and used OK ... eg Struts, Hibernate

Answer 1

Solution was to create a new empty web application, check the existing project out from SVN, regenerate the build-impl.xml & configure the library references.

All is now importing and referencing OK

I do not have an explanation as to why the problem occurred the first time this project was created
