JDK里面的tools.jar和Tomcat里lib下的tools.jar版本要一致
JDK里面的tools.jar和Tomcat里lib下的tools.jar版本要一致
在运行TOMCAT5.0时候由出现了如下的错误:
2005-11-17 19:38:47 StandardWrapperValve: Servlet.service() for servlet action threw exception org.apache.jasper.JasperException: Unable to compile class for JSP Generated servlet
error: C:\application\Tomcat 5.0\work\Catalina\localhost\mlinkweb\org\apache\jsp\layouts\layout_005findex_jsp.java:7: cannot access java.lang.Object Generated servlet error: bad class file: C:\application\Java\jdk1.5.0\jre\lib\rt.jar(java/lang/Object.class) class file has wrong version 49.0, should be 48.0 Please remove or make sure it appears in the correct subdirectory of the classpath. public final class layout_005findex_jsp extends org.apache.jasper.runtime.HttpJspBase ^ 1
error 最后在SUN的JAVA论坛里面找到了答案,只要将JDK1.5的LIB下面的TOOLS.JAR覆盖TOMCAT5.0目录/common/lib下面的tools.jar,然后重启TOMCAT5.0就可以了.
