DeploymentUtil.isSourceFolder(Unknown Source) 问题解决

1.安装后，部署工程hmsi时，出现error的一个错误对话框，但是没有错误信息。

2.检查.log文件，发现错误为java.lang.NullPointerException

3.经过分析，错误应该是在部署时找不到WebRoot，经在myeclipse-web中检查WebRoot，是/WebRoot，而我们的webroot应该是EAPDomain。

4.手工修改.mymetadata

<?xml version="1.0" encoding="UTF-8"?>
<project-module
type="WEB"
name="hmsi"
id="myeclipse.1122346865314"
context-root="/eapdomain"
j2ee-spec="1.4"
archive="hmsi.war">
<attributes>
<attribute name="webrootdir" value="EAPDomain" />
</attributes>
</project-module>

注意value="EAPDomain"，不能加/。而且修改完成后再重新启动，检查webroot是否被修改过来。修改过来后就好用了。注意这个文件的修改不能从eclipse中进行。

5.也可以新建一个工程，将其中的.mymetadata拷贝过来
