myeclipse 部署报错
Errors occurred during the build.
Errors running builder 'DeploymentBuilder' on project 'music'.
java.lang.NullPointerException
myeclipse 每次保存文件都会报这个错，网上各种查，无果
在当前workspace/.metadata下log打印如下日志
!ENTRY org.eclipse.core.resources 4 2 2011-12-01 01:07:01.490

在at com.genuitec.eclipse.ast.deploy.core.DeploymentUtil.getOutputFolder(Unknown Source)的时候出错，应该是output配置有问题。
最后在org.eclipse.wst.common.component 文件中找到原因所在
<wb-resource deploy-path="WEB-INF/classes" source-path="web/src"/>
这里的deploy-path配置不正确
我的路径是web/WebContent/WEB-INF/classes 配置好之后就ok了
我去，这样设置不能热部署了，看来原来的配置没错，估计是myeclipse的bug
