Hello,
I am planning to migrate my Struts 1 App to Struts 2.
I have a page where I am uploading files to the
server.
I tried to follow the fileupload sample that comes
with the Struts 2 distribution but without success.
In my app, I have all the required .jar files in the
WEb-INF/lib directory. You can find the parts related
to the fileupload below. It seems I am missing some
kind of "converters" that would identify that the
property upload in my form is of type "file".
Thanks for your help.

struts.xml file
---------------
<action name="TestStruts2FileUpload"
class="com.breezeware.action.TestStruts2FileUploadAction"
method="upload" >
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="basicStack"/>
<result
name="input">/tiles_jsp/dash_board.jsp</result>
<result>/tiles_jsp/dash_board.jsp</result>
</action>
----------------------------------------------------
action file:
-----------
public class TestStruts2FileUploadAction extends
ActionSupport {
private String contentType;
private File upload;
private String fileName;
public String getUploadFileName() {
return fileName;
}
public void setUploadFileName(String fileName) {
this.fileName = fileName;
System.out.println("File name = " + fileName);
}
public String getUploadContentType() {
return contentType;
}
public void setUploadContentType(String
contentType) {
this.contentType = contentType;
System.out.println("File content type= " +
contentType);
}
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String input() throws Exception {
return SUCCESS;
}
public String upload() throws Exception
{
return SUCCESS;
}
}

FileUpload.jsp page:
<form
action="/PLM/struts2/TestStruts2FileUpload.action"
method="post"
type="multipart/form-data">
File 'upload' = <input type="file" name="upload" />
<input type="submit" />
</form>

I am using JBOSS in my application server. When I try
tp upload the file, following exception is thrown (as
seen in JBOSS log).
