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>



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>?
