Eclipse is a free Java IDE tool. The default does not support Web development of JSP. But after integrating the same free Lomboz plug-in, there is a very powerful development capability of Java WebApplication programs.
How to integrate this thing online, I haven't described it here. The problem is that everyone has issued various problems after completing the settings in accordance with the steps in the article, but they cannot find the corresponding solution. As far as I personally, I encountered an identical problem in the integration of Eclipse 2.1.3 and Eclipse 3.0: unable to use Lomboz to move Tomcat servers.
After studying the error message, the individual feels that it is JRE. So I found an option option in Eclipse, and the DRE used in Eclipse is the one under your system installation. So I let Eclipse searched another JRE in my JDK installation directory and set it to Eclipse. So ................ The problem is solved. Ha ha
This is true in Eclipse 2.x and 3, if someone encounters a problem with me, try my way. I hope to help.
