公司拿到手的��目开发��^台都不统一。有的是myEclipse开发的�Q�有的是Eclipse for J2EE开发的�?span class="Apple-converted-space">

�q�里说一�U�把myEclipse��目转成Eclipse��目�l�箋开�?span class="Apple-converted-space">

1. 请首先确保你的eclipse是javaee版本的，或者已�l�安装看wtp插�g

2. 然后修改eclipse工程下的.project文�g:

3.�?lt;natures>中加�?span class="Apple-converted-space">
    org.eclipse.wst.common.project.facet.core.nature
    org.eclipse.wst.common.modulecore.ModuleCoreNature
    org.eclipse.jem.workbench.JavaEMFNature
4. �?lt;buildSpec>< ildSpec>中加�?span class="Apple-converted-space">

        org.eclipse.wst.common.project.facet.core.builder




        org.eclipse.wst.validation.validationbuilder


    < /buildCommand>
5. ��h��目�Q�项�?>叛_��->Properties->Project Facets->Modify Project�Q�选择Java和Dynamic Web Module配置Context Root 和Content Directory 以及源码路径
6. �W?步没有的话，扑ֈ��目�?setting目录�Q�修改org.eclipse.wst.common.component 里面�?span class="Apple-converted-space">

�q�两个即可，deploy-name 为工�E�名�Q�source- path= "/WebRoot "eclipse下默认�ؓWebContent修改为WebRoot

svn
http://subclipse.tigris.org/update_1.6.x
