My Notepad

The problem I have encountered:

First use "cvs import" to import a web application's WEB-INF module to CVS

On a windows machine, checkout this project using eclipse and make some modifications, then commit changes

Go back to Linux, checkout WEB-INF back to work place under tomcat.home.

Now you will find some weird errors regarding the *.jar files in WEB-INF/lib, sth like "bad LOC signature", because the jar files are corrupted.

The reason is CVS treat binary files and non-binary files differently when "add" and "commit", (also when checkout), you have to tell CVS don't merge or modify binary files to avoid file corruption.

Solution:
1. use " -kb" parameter whenever "add" or "commit" a binary file/directory to CVS repository.
2. use cvswrappers
1)checkout CVSROOT project to any workplace you want.
2)modify the cvswrappers under the workplace /CVSROOT, make it looks like:
#############cvswrappers#########

3) comit changes by: cvs commit cvswrappers
Now all the files with extenstion we specified in this file will be treated as binary(no merge, no keyword expantion, etc) by CVS during "add"/"commit".
