Struts 1.0.2 file upload problem, was working with Struts 0.5

[Hareesh Subramanya]

I am in the process of upgrading our application to struts 1.0.2 from
struts 0.5 ( I know it should have been done a lot earlier but still ... )
Everything is working as excepted except for this one problem when I try to
upload a file :

java.lang.IllegalArgumentException: argument type mismatch

I used to get a servletException:BeanUtils.populate() error before I added
debug statements and extra catch segments in BeanUtils and PropertyUtils.

My JSP segment is :

<html:form action="/SRweb/uploadQuoteBatch.do" method="post" name
="UploadQuoteBatchForm" type
= "com.xxx.acquiline.SRweb.UploadBatchQuotes.UploadQuoteBatchForm" enctype
="multipart/form-data">
<table width="100%" border="0"  cellpadding="5">
    <tr>
        <td>
            <input type="file" name="fileName" style='width:400;' class
="button" style="background-color:#FFFFFF">
        </td>
    </tr>
    <tr>
        <td>
            <input type="submit" value="Upload" name="uploadFile"  class
="button">
        </td>
    </tr>
</table>
</html:form>


If any of you have any clues why I am getting this error it would greatly
help me. Again this feature used to work with the older version of struts
but it is not working with Struts 1.0.2

Thanks,
Hareesh
