[wl199083]

Myeclipse 导入一个新的项目，然后再运行以前那个就报错，删除新的也不行，
Launching HPSSystem on Myeclipse Tomcat ' has encountered a problem
An internal error occurred during :"Launching HPSSystem on MyEclipse Tomcat";

点开详细以后

在Eclipse中按照如下操作 Project -> Properties -> Run/Debug Settings: 1. select "Launching New_configuration" 2. Delete 3. OK

你新项目部署了没有！如果部署了，找到workAPP中去，将新项目删掉。老项目没有错，是新项目部署后，错误导致老项目不能运行...
