主页面
<html:link forward="newProduct">录入产品信息</html:link>
</td>
<td>
<html:link forward="searchProduct">查询产品信息</html:link>

录入页面

<html:form action="saveProduct">

配置

<form-beans>
<form-bean name="saveProductForm" type=" mystruts.actionform.ProductForm" />
<form-bean name="searchProductForm" type="mystruts.actionform.ProductForm" />
</form-beans>
<global-exceptions />
<global-forwards>
<forward name="newProduct" path="/newProduct.jsp" />
<forward name="searchProduct" path="/searchProduct.jsp" />
</global-forwards>

查询都可以，为什么录入就打不开啦。

[解决办法]
<form-bean name="saveProductForm" type=" mystruts.actionform.ProductForm" />
把type里面的空格去掉试试
type=" mystruts.actionform.ProductForm" ——>type="mystruts.actionform.ProductForm"
[解决办法]
你struts在web.xml里配置了吗
