我的jsp :hello.jsp
?
code1 :
<html> <OL> <LI><jsp:include page="/header.jsp" flush="true"/> <LI><jsp:include page="/a.txt" flush="true"/> <LI><jsp:include page="/a.txt" flush="true"/> <LI><jsp:include page="/a.txt" flush="true"/> </OL> </html>
?

code 2 :
?
<html> <OL> <LI><jsp:include page="/header.jsp" flush="true"/> <LI><jsp:include page="/a.txt" flush="true"/> <LI><jsp:include page="/a.txt" flush="true"/> <jsp:forward page="/a.txt" /> <LI><jsp:include page="/a.txt" flush="true"/> </OL> </html>
?
当加入<jsp:forward page="/a.txt" />后,第三个LI 的内容就不会被显示,why ?。
?

生成的 hello_jsp.java 如下 :如果程序按顺序执行的话,应该没有问题的,不懂为什么不显示
?
out.write("<OL>\r\n"); out.write("\r\n"); out.write("<LI>"); org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "/header.jsp", out, true); out.write("\r\n"); out.write("\t\t\r\n"); out.write("<LI>"); org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "/a.txt", out, true); out.write("\r\n"); out.write("\t\r\n"); out.write("<LI>"); org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "/a.txt", out, true); out.write('\r'); out.write('\n'); out.write(' '); if (true) { _jspx_page_context.forward("/a.txt"); return; } out.write("\r\n"); out.write("<LI>"); org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, "/a.txt", out, true); out.write("\r\n"); out.write("</OL>\r\n");
