hi all
i put it in the jsp, and here is the code generate by  tomcat
i did not see if there is any wrong there.

package org.apache.jsp;

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import java.util.*;

public final class jsp1_jsp extends org.apache.jasper.runtime.HttpJspBase
   implements org.apache.jasper.runtime.JspSourceDependent {

 private static java.util.List _jspx_dependants;

 public Object getDependants() {
   return _jspx_dependants;
 }

 public void _jspService(HttpServletRequest request, HttpServletResponse
response)
       throws java.io.IOException, ServletException {

   JspFactory _jspxFactory = null;
   PageContext pageContext = null;
   HttpSession session = null;
   ServletContext application = null;
   ServletConfig config = null;
   JspWriter out = null;
   Object page = this;
   JspWriter _jspx_out = null;
   PageContext _jspx_page_context = null;


   try {
     _jspxFactory = JspFactory.getDefaultFactory();
     response.setContentType("text/html; charset=GB2312");
     pageContext = _jspxFactory.getPageContext(this, request, response,
        null, true, 8192, true);
     _jspx_page_context = pageContext;
     application = pageContext.getServletContext();
     config = pageContext.getServletConfig();
     session = pageContext.getSession();
     out = pageContext.getOut();
     _jspx_out = out;

     out.write("\r\n");
     out.write("\r\n");
     out.write("\r\n");
     out.write("\r\n");
     out.write("<html>\r\n");
     out.write("<head>\r\n");
     out.write("<title>\r\n");
     out.write("jsp1\r\n");
     out.write("</title>\r\n");
     out.write("</head>\r\n");
     out.write("<body bgcolor=\"#ffffff\">\r\n");
     out.write("<h1>\r\n");
     out.write("JBuilder Generated JSP\r\n");

List alist =new ArrayList();
alist.add(0);
out.print(alist.get(0));
//Gentest gt=new Gentest();
//gt.addalist();
//gt.addlist();

     out.write("\r\n");
     out.write("</h1>\r\n");
     out.write("<form method=\"post\" action=\"jsp1.jsp\">\r\n");
     out.write("<br><br>\r\n");
     out.write("<input type=\"submit\" name=\"Submit\"
value=\"Submit\">\r\n");
     out.write("<input type=\"reset\" value=\"Reset\">\r\n");
     out.write("</form>\r\n");
     out.write("</body>\r\n");
     out.write("</html>\r\n");
   } catch (Throwable t) {
     if (!(t instanceof SkipPageException)){
       out = _jspx_out;
       if (out != null && out.getBufferSize() != 0)
         out.clearBuffer();
       if (_jspx_page_context != null)
_jspx_page_context.handlePageException(t);
     }
   } finally {
     if (_jspxFactory != null)
_jspxFactory.releasePageContext(_jspx_page_context);
   }
 }
}

hmm, do you use this code in a jsp? Could you possible check the
source code generated by tomcat for this jsp and inspect it / send it
to us? Sounds like your jsp compiler is buggy.
