各位大哥, 小弟做了一个 公司网站, 前台用TOMCAT 后台用MYSQL 做数据库. 在本机上运行正常, 当我在别的机器上测试时.. 我配置好了 TOMCAT ,建立了站台, 网站目录, 三个, HTML IMAG 和WEB-INF. WEB-INF 的XML 配置. 也正确. 但是, 在浏览时却出现以下错误. type Exception report

message

exception

org.apache.jasper.JasperException: Unable to compile class for JSP

No Java compiler was found to compile the generated source for the JSP. This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK to the common/lib directory of the Tomcat server, followed by a Tomcat restart. If using an alternate Java compiler, please check its installation and access path.

note The full stack trace of the root cause is available in the Tomcat logs. 不知所'错'

你的ｃｌａｓｓｐａｔｈ不是很正确了哈，具体好像少了一个ｔｏｏｌｓ．ｊａｒ

问题出在：This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
建议在classpath后增加jdk/lib/tools.jar,
若不能解决，建议你装jdk1.5.0，classpath＝
              您的安装目录\lib\tools.jar;

                 您的安装目录\dt.jar;

                 您的安装目录\bin;

                 您tomcat的安装目录\common\classes;

                 您tomcat的安装目录\common\lib;

                 您tomcat的安装目录\common\lib\servlet-api.jar;
