Web项目lib下的jar包无法自动加载

Web项目复制到lib下的jar包不自动加载

打开项目的Java source目录，发现没有web app libraries目录

解决：

打开项目源码，打开.classpath文件，内容如下

<classpath>

            <classpathentrykind="src" path="src"/>

            <classpathentrykind="con"path="melibrary.com.genuitec.eclipse.j2eedt.core.MYECLIPSE_JAVAEE_5_CONTAINER"/>

<classpathentry kind="con"path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">

                       <attributes>

                                   <attributename="owner.project.facets" value="java"/>

                       </attributes>

            </classpathentry>

            <classpathentrykind="output" path="WebRoot/WEB-INF/classes"/>

</classpath>

对比可以自动加载的项目的.classpath文件

<classpath>

            <classpathentrykind="src" path="src"/>

            <classpathentrykind="con" path="com.genuitec.eclipse.j2eedt.core.J2EE14_CONTAINER"/>

            <classpathentrykind="con" path="org.eclipse.jdt.USER_LIBRARY/MyJars"/>

            <classpathentrykind="con"path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7">

                        <attributes>

                                   <attributename="owner.project.facets" value="java"/>

                       </attributes>

             </classpathentry>

<classpathentrykind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>

<classpathentrykind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>

          <classpathentrykind="output" path="WebRoot/WEB-INF/classes"/>

</classpath>

添加这一句：<classpathentry kind="con"path="org.eclipse.jst.j2ee.internal.web.container"/>   重启eclipse即可
