hi all,

We are using Apache FileUpload 1.1.1 package in our application for uploading purposes. We are getting some exceptions which we couldn't trace it out. Could anyone please help us out .

Our part of code which throws exception goes like this :

<%

// Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();


// Set factory constraints
factory.setSizeThreshold(4096);
factory.setRepository(new File("D:/tmp"));

try{

// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);

// Set overall request size constraint
upload.setSizeMax(6000);

// Parse the request
List items = upload.parseRequest(request);

}catch(Exception e){
out.println(e);
}


%>



Exceptions we came across :

javax.servlet.ServletException: org.apache.commons.fileupload.servlet.ServletFileUpload.parseRequest
(Lorg/apache/commons/fileupload/RequestContext;)Ljava/util/List;
