jsp代码
注意，form的enctype和input的type
<form name="baseInfoForm" method="post"
enctype="multipart/form-data" id="form1">
<input type="file" name="pic" />
</form>
struts-config.xml
动态表单的类型设置，注意看类型
<form-bean name="baseInfoForm"
type="org.apache.struts.action.DynaActionForm">
<form-property name="pic" type ="org.apache.struts.upload.FormFile"/>
java处理

上传组件
struts包 包含了这个org.apache.struts.upload就可以上传。
