我想把原来做的JAVABEAN源文件用JAVAC重编译一下可出现找不到引用的包的问题，请高手解决一下。我用了oracel的驱动和JSP 标签所用的类javax.servlet.jsp.tagext.*我的classpath中c:\j2sdk1.4.2_01\lib\tools.jar;c:\j2sdk1.4.2_01\lib\dt.jar;c:\j2sdk1.4.2_01\lib\jsdk.jar;C:\j2sdk1.4.2_01\lib;D:\work\web\gsbx\WEB-INF\classes;D:\work\web\gsbx\WEB-INF\classes\oracle;D:\work\work_code\java_require_lib其中java_require_lib目录下包括classes111.zip classes12.zip
我运行时javac -d mybean/*.java还是出现出现找不到引用的包
错误如下:出现找不到引用的包  请高手解决一下。
