With reference to the file uploading example int following link http://jakarta.apache.org/struts/faqs/actionForm.html
I have a question.
I have an almost similar example to run, using a String to retrieve the file name instead of FormFile object.
However I am facing the following problem.
My form tag is like this.
<html:form action="/Upload" name="uploadForm" type="xyz.UploadForm">
In my Action file's execute() method, I try to parse the uploaded file using MultipartParser.
However the parser does not happen since the contentType is not multipart/form-data.
If I change the tag to include the enctype as follows
<html:form action="/Upload" name="uploadForm" type="xyz.UploadForm" enctype="multipart/form-data">
I get the following error
javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:954)
at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:795)
at org.
followed by
root cause
java.lang.IllegalArgumentException: argument type mismatch
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
at
Can I know what is the probable cause of this ?
Is adding the enctype tag in the form tag not the only requirement ?
If I dont use struts, I dont face such a problem and the file gets uploaded.
Here are the relevant tags in my struts-config.xml
<form-bean name="uploadForm"
type="xyz.UploadForm"/><action-mappings>
<action path="/Upload"
type="xyz.UploadAction"
name="uploadForm"
scope = "request"
input="/Upload.jsp">
<forward name="success" path="/UploadSuccess.jsp"/>
<forward name="failure" path="/Error.jsp"/>
</action></action-mappings>
