Question

jsp源码中classpath文件、.mymetadata文件、.project文件是如何创建的，具体起到什么作用呐？

附classpath文件和.project文件 .project文件

classpath文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="con" path="com.genuitec.eclipse.j2eedt.core.J2EE14_CONTAINER"/>
<classpathentry kind="lib" path="WebRoot/WEB-INF/lib/sqljdbc.jar"/>
<classpathentry kind="output" path="WebRoot/WEB-INF/classes"/>
</classpath>

project文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<project-module
type="WEB"
name="ProductProject"
id="myeclipse.1218595713531"
context-root="/ProductProject"
j2ee-spec="1.4"
archive="ProductProject.war">
<attributes>
<attribute name="webrootdir" value="WebRoot" />
</attributes>
</project-module>

.project文件
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>ProductProject</name>

看起来好像是Eclipse自动生成的项目配置文件

这些文件是自动生成的，目的是让Eclipse识别这个文件夹是Eclipse的项目文件夹
