原因及解决方法：

SSH整合jar包冲突的问题。例如：在使用Spring的AOP编程时，会用到这几个lib： asm- 2.2.2.jar asm-commons-2.2.2.jar asm-util-2.2.2.jar 如果使用Hibernate 会用到这几个lib： asm.jar asm-attrs.jar其中asm-2.2.2.jar与asm.jar存在类上的冲突

打开Windows->Preferences->Project Libraries

点击Enable advanced configuration，去掉antlr2.7.2.jar就行了

错误2

java.lang.IllegalArgumentException: Page directive: invalid value for import

原因及解决方法：

仔细检查发现是<%@ page import=” java.util.;”%>一句引起的错误。把<%@ page import=” java.util.;”%>中的分号去掉就好了，改为：

<%@ page import=” java.util.*”%> 所以以后写import要规范。
