在哪里可以找到编译 servlet 所需的 javax.servlet 类？

Question

我在这个问题上花了很多时间，我需要 javax.servlet.Servlet（还有 javax.persistence）可用。我下载了它并将其放在我认为有意义的所有位置（C:\Program Files\Java\jdk1.6.0_20\lib ... C:\Sun\SDK\lib [Glassfish 目录] ）。我不断收到有关此问题的错误。任何线索或提示表示赞赏。

这是我运行“ant”时遇到的错误：

    [javac]     public void service(HttpServletRequest request, HttpServletRespo
nse response) throws ServletException, IOException;
    [javac]                         ^

这是 command-line-ant-tasks.xml 的一部分：

<dirname property="antfile.dir" file="${ant.file}"/>
<path id="classpath">
    <fileset dir="${javaee.home}" includes="lib/javaee.jar, lib/appserv-rt.jar, lib/appserv-ws.jar"/>
    <pathelement location="${build.classes.dir}"/>
    <pathelement path="${javac.classpath}"/>
    <pathelement path="${extra.classpath}"/>
    <path refid="javaee.classpath" />
</path>

<!-- the includeantruntime was added 8/31 -cp="C:\servlet"  -->
<target name="bpp-actual-compilation" if="has-java-sources">
    <echo>Compiling ${module.name}</echo>
    <mkdir dir="${build.classes.dir}"/>
    <javac srcdir="${src.dir}"
        source="${default.javac.source}"
        target="${default.javac.target}"
        excludes="${javac.excludes}"
        debug="${javac.debug}"

        debuglevel="${javac.debuglevel}"

        includeantruntime="false"
        includes="**">
        <classpath refid="classpath"/>
    </javac>
</target>

我认为这是 build.xml 的相关部分：

<target name="insert-proxy-settings">
    <copy todir="${build.web.dir}/WEB-INF/" file="web/WEB-INF/web.xml"/>
    <concat destfile="${build.dir}/proxy.properties">proxy.host=${proxy.host}
        proxy.port=${proxy.port}
        <filterchain>
            <expandproperties/>
        </filterchain>
    </concat>
    <!-- Replace value of the proxy settings in web.xml for Google maps -->
    <replace file="${build.web.dir}/WEB-INF/web.xml" propertyFile="${build.dir}/proxy.properties">          
        <replacefilter token="@@proxy.host@@" property="proxy.host"/>
        <replacefilter token="@@proxy.port@@" property="proxy.port"/>
    </replace>        
</target>

<target name="unzipIndexes">
    <unzip src="lib/petstoreIndexes.zip" dest="${javaee.domaindir}/lib/petstore" overwrite="true"/>
</target>

我认为这是xml的相关部分

我假设您下载了 servlet-xx.jar 或类似的文件，以及另一个用于持久性类的文件。这些应该位于 ant 构建脚本中的类路径引用的 lib 目录中。然后需要将它们添加到上面的 ant 构建脚本行中。即，将“lib/servlet-xx.jar, lib/persistence.jar”添加到该行的末尾，以获取包含=“...”值。

将下载的 jar 的实际名称替换为我上面使用的名称。
