javac 目标版本 1.3 与默认的源版本 1.5 冲突

开发JSP，使用Eclipse（JDK1.5），部署WEB应用Tomcat5.0.29
请求JSP时，Tomcat日志显示“javac: 目标版本 1.3 与默认的源版本 1.5 冲突”
查看上面的错误日志，发现"compilerTargetVM=1.3"，应该时Tomcat的JSP编译时使用的JDK1.3的版本。
进行如下修改：

找到tomcat conf目录下的web.xml，将这段内容：

<servlet>
    <servlet-name>jsp</servlet-name>
     <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
        <param-name>fork</param-name>
         <param-value>false</param-value>
    </init-param>
    <init-param>
        <param-name>xpoweredBy</param-name>
         <param-value>false</param-value>
    </init-param>
     <load-on-startup>3</load-on-startup>
</servlet>

    <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>false</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

改为如下

<servlet>
      <servlet-name>jsp</servlet-name>
       <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
      <init-param>
      <param-name>compilerSourceVM</param-name>
       <param-value>1.5</param-value>
      </init-param>
      <init-param>
      <param-name>compilerTargetVM</param-name>
       <param-value>1.5</param-value>
      </init-param>
      <init-param>
          <param-name>fork</param-name>
           <param-value>false</param-value>
      </init-param>
      <init-param>
        <param-name>compiler</param-name>
        <param-value>modern</param-value>
      </init-param>
      <init-param>
          <param-name>xpoweredBy</param-name>
           <param-value>false</param-value>
      </init-param>
       <load-on-startup>3</load-on-startup>
  </servlet>
