我使用Eclipse的休眠，当我尝试编译不断收到以下错误信息：日志厂错误
build.xml:39: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
我有commons-logging.jar文件我libs文件夹内，这里是我的类路径文件：
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER">
<attributes>
<attribute name="owner.project.facets" value="java"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimeTarget/Apache Tomcat v6.0">
<attributes>
<attribute name="owner.project.facets" value="jst.web"/>
</attributes>
</classpathentry>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.web.container"/>
<classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>
<classpathentry kind="src" path="flex_src"/>
<classpathentry kind="output" path="build/classes"/>
</classpath>
我甚至尝试从build.xml文件中打印的类路径和commons-logging.jar出现内有作为，有正确的目录。这里是我的build.xml文件供进一步参考：

不幸的是，我已经尝试将jar复制到服务器的lib目录中，但没有运气 –
如何在服务器中部署此项目？你打开了可部署的存档吗？ （解压缩..）你有没有找到common.loggin.jar。可能你有一个不同版本的jar文件。你是否也可以打开common.logging.jar文件并查看包“org.apache.common.logging”是否存在。 –
包确实存在于jar文件中。我也不确定您的可部署归档文件的含义。在脱机构建文件的过程中，我收到了这些错误，没有涉及Tomcat。这不妨碍它成为服务器问题吗？ –
