Every time I copy a JSP (.jsp) file from a folder to another one the IDE adds a package to the top of the file. I have a
project which has a set of defaults. If a file is copied into another folder of the same layout under a custom folder it
overrides the default file and may be changed without changing the original software, and this is why I'm copying .jsp
files a lot. Anyways, I simply:
1) click on a .jsp file in a sub-folder or the top folder (.) of the web view of a web project.
2) choose to copy the file
3) locate another sub-folder under the web view
4) right click on it
5) choose paste
6) open the file
7) notice a package statement, an error, in the JSP file

a quick way to reproduce is:

1) Create a new web project from the New->Project wizard and choose no frameworks
2) Right click on "Web Pages"
3) Create a new folder called "test"
4) Right click on index.jsp and copy it
5) Right click on "Web Pages"/"test" and choose paste
6) open "Web Pages"/"test"/index.jsp
7) notice the package

I wasn't 100% sure which subcomponent to place this in, so I chose code. My current environment is openSuSE 11, JDK
1.6_7, and a build of NB 6.5 main from this morning (081001). This has happened on Windows XP SP2 as well (same version
of the JDK).
