[sagittarius1979]

你的jsp中(taglibs.jsp)开头定义了两个或两个以上contentType.如contentType="text/html;charset=xxx"。

有可能你的jsp中引入(<%include file="xxxxxxxx"%>)了其他的jsp，而其他的jsp也包含了contentType的定义

[liuyonghailiuyong]

同意，我也遇到过类似情况，就是用<%include file="sss"%>的时候，正好那个文件里也包含了contentType的定义，很挠心的！

org.apache.jasper.JasperException: /taglibs.jsp(0,0) Page directive:

can't have multiple occurrences of contentType

multiple occurrences of contentType有可能你的jsp中引入(<%include file="xxxxxxxx"%>)了其他的jsp，而其他的jsp也包含了contentType的定义

[javacomte]

在动态包含jsp文件时被包含jsp文件不能指定contentType，否则就会出现上面的问题。而静态包含时必须指定，否则就会出现乱码。你把被包含文件中的contentType去掉就行了。

[追求自由]

对，是头文件重复了。有些server就不会出现这样的问题。
