If you don’t see “Designer” in the list of plugins:Check that you have installed the correct version of Designer for the version of Eclipse/WSAD that you are using.
Check for error messages in file: $ECLIPSE$\workspace\.metadata\.log
Shutdown Eclipse, delete this file, start Eclipse again, and try to use Designer. This process will remove old error messages and only include messages about the Designer or Eclipse loading process in the file listed above..
Include the "-clean" option on the command line that starts up Eclipse 3.x. This causes Eclipse 3.x to recache all of its plug-in information on startup so that new and revised tools. Once the plug-in information has been recached and Designer appears as expected, you can remove the "-clean" option.

在eclipse的gui项目中,指向要打开的java文件;
然后open with->designer Editor就可以了;
换了机器后,默然打开方式是java Editor.
