在Eclipse3.0.0/3.0.1下使用sysdeo的tomcat plug-in3.0.0版本出现，Eclipse中的有些project不能被加入tomcat的classpath，因为这些project根本无法tomcat配置画面中Listed。
这个问题居然还在sysdeo自己的realsenote中说是fixed，真是晕倒。(见最末附文)
我已经发信给sysdeo了，希望能够尽快解决。
毕竟，sysdeo3.0.0比以前功能加强不少，而且对tomcat5.0的支持也更好。

-------------------------
Version 3.0
------------
New features :
- in main preference page add a way to choose how contexts are declared :
- definition in server.xml (previous version allowed only this)
- creation of a context file (recommended way with Tomcat 5)
- add an 'advanced' preference page to simplify the main preference page.
- add a field in Tomcat properties page to set extra information to generated context definitions
- Tomcat projects build path are automatically updated when Tomcat version is changed
Fixed :
- It is no more possible to add Tomcat projects to Tomcat classpath (they won't be listed in preference page)
- TOMCAT_HOME was added to project build path (when Tomcat 4 was selected in Tomcat preferences).
Before Eclipse 3.0 (final release) this could make Eclipse hangs, see this bug report https://bugs.eclipse.org/bugs/show_bug.cgi?id=64646
Eclipse 3.0 won't build the project.
Many thanks to Jerry Lampi
- Enable to start Tomcat or to open Tomcat project properties when using DevLoader and allowing circular dependencies for Java projects.
- By default, new Tomcat projects were not added to source path
- When using Tomcat 5, Eclipse does not stop on breakpoints set in generated java files for JSP. This is fixed only for new Tomcat projects, for existing ones follow those steps :
- Edit your Tomcat project Java Build Path
- in 'Source' tab, check 'Allow output folders for source folders'
- in the list named 'Source folders on build path', select '%Your_project%/work' and 'Output Folder'
- select the 'Edit' button, check 'Specific output folder' and enter 'work' in the text field.
