jjsp(59,55) Attribute qualified names must be unique within an element

从tomcat 6 升到 tomcat-7.0.12

jsp页面报:

org.apache.jasper.JasperException: /XXX/XXX.jsp(59,55) Attribute qualified names must be unique within an element

    org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:41)
    org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407)
    org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:88)....

 

原因:页面一个struts标签中定义了两个id属性的(工具没提示).

tomcat6正常，解析后取第二个id的值

 

如果非struts标签,页面解析后只取第一个属性

 

 

jsp(97,87) The JSP specification requires that an attribute name is preceded by whitespace

 

原因: struts标签 属性 之间要有空格
