用eclipse 新建J2EE項目,自動生產(chǎn)的index.jsp..在lomboz view運行tomact5.0 出現(xiàn)一下錯誤..但把此文件直接復制到"C:\Tomcat 5.0\webapps\ROOT"可以正常顯示..
源碼如下:


  3. <html>;
  4.         <head>;
  5.                 <title>;Welcome</title>;
  6.         </head>;
  7.         <body>;
  8.                 <center>;Welcome</center>;
  9.         </body>;
  10. </html>;
