Posted by: 512mouse Posted on: 2004-09-03 15:30 我把beanSpellCheck编译成.class文件之后,不知道放在哪,最后就放在和jsp,html一个目录下了(D:\Apache Tomcat 4.0\webapps\myapps). 然后:从浏览器http://localhost:8080/myapps/My.html中进入,输入几个字母,再点submit.出现一大堆错误如下: org.apache.jasper.JasperException: Unable to compile class for JSPNote: sun.tools.javac.Main has been deprecated. An error occurred between lines: 7 and 8 in the jsp file: /wordpro.jsp Generated servlet error: D:\Apache Tomcat 4.0\work\Standalone\localhost\myapps\wordpro$jsp.java:73: Undefined variable or class name: help ? help.reverse():""+help.check()); ^ An error occurred between lines: 7 and 8 in the jsp file: /wordpro.jsp Generated servlet error: D:\Apache Tomcat 4.0\work\Standalone\localhost\myapps\wordpro$jsp.java:73: Undefined variable or class name: help ? help.reverse():""+help.check()); ^ 2 errors, 1 warning at org.apache.jasper.compiler.Compiler.compile(Compiler.java:285) at org.apache.jasper.servlet.JspServlet.loadJSP(JspServlet.java:548) at org.apache.jasper.servlet.JspServlet$JspServletWrapper.loadIfNecessary(JspServlet.java:176) .............................................. 请各位XDJM帮帮偶 |
