How to get string parameter from request when using enctype="multipart/form-data" ?

Hi guys,

Descriptions:

When [ <form> tag ] which has enctype="multipart/form-data"  and also contain additional input type="text" with name="username" and a submit button.

jsp:

<form action="upload" method="post" enctype="multipart/form-data">
User Name: <input type="text" name="username" /><br/>
<input type="file" name="file" />
<input type="submit" value="upload" />
</form>

retrieve string paramName as:
String username = request.getParameter("username"); 
That's prints NULL when form has enctype="multipart/form-data"  If I remove this attributes from the form tag then prints value input by user. 


Whenever a form has enctype="multipart/form-data" . You can not get other form fields by using request.getParameter("paramName");
It will always give you NULL value.

*This problem can be resolved by using below way.

Write the below code in your servlet and get the values of additional formfields :

   List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
   String inputName = null;
for(FileItem item : multiparts){
if(!item.isFormField()){   // Check regular field.
String name = new File(item.getName()).getName();
item.write( new File(UPLOAD_DIR + File.separator + name));
}
if(item.isFormField()){  // Check regular field.
inputName = (String)item.getFieldName(); 
if(inputName.equalsIgnoreCase("username")){ 
username = (String)item.getString(); 
        System.out.println("UserName is:"+username); 
}
}
}

That's All !!
Let me know if u have any suggestions/queries, I would like to hear from your side.
