window环境编写jsp,上传到网站(linux服务器),访问servlet出404错误!
在window系统测试没有错误, 上传后访问html,jsp都没有问题,但是一旦有表单跳转到servlet,马上就报404错误!
这是managerLogin.jsp页面的内容:
<%@ page contentType="text/html; charset=gbk" language="java"%><html><head><title>SEIE Website Manager</title><link href="style/se.css" type="text/css" rel="stylesheet"/><script language="javascript" type="text/javascript" src="style/se.js"></script></head><body><table width="100%" height="100%"><tr><td align="center" vlign="middle"><form id="managerform" name="managerform" method="post" action="Ser_ManagerLogin"><table width="400" height="300" border="0" cellpadding="0" cellspacing="0" style="border-left:1px solid; border-right:1px solid; border-bottom:1px solid; border-top:1px solid; border-color:#000000; vertical-align:middle; margin-left:auto;margin-right:auto;" valign="center"> <tr> <th colspan="2" scope="col"><img src="img/websiteManager.jpg" alt="website Manager" width="400" height="138" /></th> </tr> <tr> <td height="18" colspan="2" bgcolor="#666666"></td> </tr> <tr> <td height="18" colspan="2" bgcolor="#FFFFFF"></td> </tr> <tr> <td width="200" height="18" align="right" bgcolor="#FFFFFF">UserName: </td> <td align="left" bgcolor="#FFFFFF"><input type="text" name="username" id="username" onkeypress="javascript:mgrLoginOnKey(event);"/></td> </tr> <tr> <td height="18" colspan="2" bgcolor="#FFFFFF"></td> </tr> <tr> <td width="200" height="18" align="right" bgcolor="#FFFFFF">Password: </td> <td height="18" align="left" bgcolor="#FFFFFF"><input type="password" name="password" id="password" onkeypress="javascript:mgrLoginOnKey(event);"/></td> </tr> <tr> <td height="18" colspan="2" bgcolor="#FFFFFF"></td> </tr> <tr> <td height="18" colspan="2" align="center" bgcolor="#FFFFFF"> <a onFocus="if(this.blur)this.blur()" onClick="javascript:checkmanagerform();return false;" style="cursor:pointer;"> Login </a> <a href="index.jsp">Home</a> </td> </tr> <tr> <td height="18" colspan="2" bgcolor="#FFFFFF"></td> </tr> <tr> <td height="18" colspan="2" bgcolor="#FFFFFF"></td> </tr> </table> </form> </td> </tr> </table></body></html>

[解决办法]
设置apache的mod_jk2，把/Ser_ManagerLogin的请求转到tomcat
[解决办法]
<url-pattern>/Ser_ManagerLogin</url-pattern>
<form id="managerform" name="managerform" method="post" action="/Ser_ManagerLogin">
我更趋向于这个，其实你可以手动测试一下，因为404肯定是找不到的异常，不是程序异常。
100%是你输入的url路径问题。

不同的Jdk環境也可能導致你的java文件在linux上編譯出錯，同樣無法生成class文件，servlet當然找不到了，所以404
最好你在相同或相似的條件測試一下，windows系列與unix系列會有很大區別的。

你在windows下把项目打包成war文件，再传到linux下的tomcat去运行，可以这样试一下，
因为你在windows下做的项目跟linux下的有很多东西都不一样了，不如jdk，tomcat，环境变量，环境。。。。。。。 打包以后在linux下不会出现这种情况了，jdk的版本要1.4以上的
