I hava downloaded the "derby_core_plugin"and"derby_ui_plugin" from the Apache Derby website,and have unzipped these two files in the Eclipse plugins file.But when I restarted Eclipse I found these two plugins uninstalled,and I still can't use it. So could you please tell me what's wrong with Eclipse or what should I do to use these two plugins.
Whether the latest version of Eclipse can not use these two plug-ins.Because the latest release of the Derby don't have these two plugin in it,and then I found the information about the Eclipse plugin on the site of Apache.It says that the two plugins can be downloaded in previous versions.
If this reason would work, could you please tell me how to use the Eclipse more effectively to develop derby or how can I construct Derby database visually.I would really appreciate if you could give me a replay. Thank you very much!
