Eclipse+Tomcat+Lomboz搭建Jsp、Servlet和JavaBean环境

还有Servlet和JavaBean环境的配置时要测试的Text.Java程序无法编译，
package test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Test extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out=response.getWriter();
out.println("<html>");
out.println("<body>");
out.println("<h1>This is a servlet test.</h1>");
out.println("</body>");
out.println("</html>");
out.flush();
}
}

出现如下提示：
C:\Test>javac Test.java
Test.java:4: package javax.servlet does not exist
import javax.servlet.ServletException;
^
Test.java:5: package javax.servlet.http does not exist
import javax.servlet.http.HttpServlet;

Test.java:6: package javax.servlet.http does not exist
import javax.servlet.http.HttpServletRequest;
^
Test.java:7: package javax.servlet.http does not exist
import javax.servlet.http.HttpServletResponse;
^
Test.java:8: cannot resolve symbol

ponse)

Test.java:9: cannot resolve symbol

location: class test.Test
protected void doGet(HttpServletRequest request, HttpServletResponse res
ponse)
^
Test.java:10: cannot resolve symbol
symbol : class ServletException
location: class test.Test
throws ServletException, IOException {
^
8 errors

可HelloWorld.java能编译的，还有打开Tomcat5.0后
C:\Tomcat 5.0\webapps\jsp-examples里的测试程序能在IE浏览器里通过
C:\Tomcat 5.0\webapps\myapp里的测试不能通过！
谢谢高手们~ 展开

5月25日 09:28 从新再装一次吧,在试试把jdk换成1.5的试试,eclipse有时候很多问题,新手往往不知道怎么回事,莫名其妙的,再装一次,我当时就装了好几次,呵呵,比较麻烦~:)
