Sometimes in a Java project where we need to add third-party jar package, when you join the best relative path, not the absolute path. Otherwise, get your project elsewhere on the No running. Means is that your best work to the relevant jar into the directory. For the Web works is relatively simple, web project is a lib directory. Directly copied to here on the line. Rather than the web works is not. Eclispe can not automatically import the copy of the. This requires us to manually configure, the job description file, Eclipse and MyEclpse all be described with xml.

Now we take a look at Eclipse's. Classpath file:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <!--  Source directory   -->
    <classpathentry kind="src" path="src"/>
    <!-- JDK Runtime container   -->
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
    <!--  Following is a class library path to your custom directory   -->
    <classpathentry kind="lib" path="lib/swing-layout-1.0.3.jar"/>
    <classpathentry kind="lib" path="lib/AbsoluteLayout.jar"/>
    <classpathentry kind="lib" path="lib/jtds-1.2.2.jar"/>
    <classpathentry kind="lib" path="lib/jxl.jar"/>
    <!--  The compiled output class directory    -->
    <classpathentry kind="output" path="bin"/>
</classpath>

In the xml I've added in comment. Think you get the idea.

. Project file:

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
    <!--  Name of project   -->
    <name>execlInterface</name>
    <comment></comment>
    <projects></projects>
    <!--  The compiler specify   -->
    <buildSpec>
        <buildCommand>
            <name>org.eclipse.jdt.core.javabuilder</name>
            <arguments></arguments>
        </buildCommand>
    </buildSpec>
    <!--  A core feature   -->
    <natures>
        <nature>org.eclipse.jdt.core.javanature</nature>
    </natures>
</projectDescription>

Myeclipse project for one more. Mymetadata file:

<?xml version="1.0" encoding="UTF-8"?>
<!--
    type :  The project type
    name :  Name of project
    id   :  Project in the workspace in the unique identity of the
    context-root :  The Web site root path
    j2ee-spec: J2EE Standard
    archive :  After the war file to package
 -->

<project-module
  type="WEB"
  name="upload"

  context-root="/upload"
  j2ee-spec="1.4"
  archive="upload.war">
  <attributes>
  <!-- value : Web Root name   -->
    <attribute name="webrootdir" value="WebRoot" />
  </attributes>
</project-module>

In the project have also encountered such a situation:

MyEclipse web project that can not be released, the reason lies in here. Mymetadata this file, which may be damaged or lost. Based on the above to explain themselves to create a project directory can be released into the web project.
