to DreamHead(大头):它们的区别我是知道的，可能是我写的不清楚。在jbuilder中使用单步执行，当出来以下信息后就没有动静了。E:\application\j2sdk1.4.0\bin\javaw -classpath "E:\application\JBuilder 6.0 Enterprise\jakarta-tomcat-3.2.3\lib\webserver.jar;E:\application\JBuilder 6.0 Enterprise\jakarta-tomcat-3.2.3\lib\jasper.jar;E:\application\JBuilder 6.0 Enterprise\jakarta-tomcat-3.2.3\lib\parser.jar;E:\application\JBuilder 6.0 Enterprise\jakarta-tomcat-3.2.3\lib\jaxp.jar;E:\application\JBuilder 6.0 Enterprise\jakarta-tomcat-3.2.3\lib\servlet.jar;E:\application\j2sdk1.4.0\jre\lib\charsets.jar;E:\application\j2sdk1.4.0\jre\lib\jaws.jar;E:\application\j2sdk1.4.0\jre\lib\jce.jar;E:\application\j2sdk1.4.0\jre\lib\jsse.jar;E:\application\j2sdk1.4.0\jre\lib\rt.jar;E:\application\j2sdk1.4.0\jre\lib\sunrsasign.jar;E:\application\j2sdk1.4.0\jre\lib\ext\dnsns.jar;E:\application\j2sdk1.4.0\jre\lib\ext\ldapsec.jar;E:\application\j2sdk1.4.0\jre\lib\ext\localedata.jar;E:\application\j2sdk1.4.0\jre\lib\ext\sunjce_provider.jar;E:\application\j2sdk1.4.0\lib\dt.jar;E:\application\j2sdk1.4.0\lib\htmlconverter.jar;E:\application\j2sdk1.4.0\lib\tools.jar;E:\application\j2sdk1.4.0\demo\plugin\jfc\Java2D\Java2Demo.jar;E:\application\j2sdk1.4.0\demo\jfc\Java2D\Java2Demo.jar" -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_shmem,address=javadebug,suspend=y org.apache.tomcat.startup.Tomcat -config F:\my_bag\JBuilder6.0\ServletProgram_Study\conf\server8082.xml 2003-01-09 21:58:57 - ContextManager: Adding context Ctx( )Starting tomcat.

比如说： package servletprogram_study;import javax.servlet.*; import javax.servlet.http.*; import java.io.*; import java.util.*;public class Servlettest extends HttpServlet { private static final String CONTENT_TYPE = "text/html; charset=GBK"; public void init() throws ServletException { } public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType(CONTENT_TYPE); PrintWriter out = response.getWriter(); out.println("<html>"); out.println("<head><title>Servlettest</title></head>");
String str=""; for(int i=0;i<10;i++){//此处设了个断点 str=str+"*"; } out.println(str); out.println("<body>"); out.println("<p>The servlet has received a GET. This is the reply.</p>"); out.println("<p>You needn't reply.(get)</p>"); out.println("</body></html>"); } public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request,response); } //Clean up resources public void destroy() { } }我按单步执行，它根本就不会去停留我在断点位置。请提示应该怎么办？
