NoSuchMethodError - IWDModifiableBinaryType

Question

Hi Friends,
I am trying Fileupload UI element. I have created a value attribute of type Binary and mapped it to UI.
On click of a submit button, I am checking if the attribute is empty. Below is the code for onAction:
IPrivateAppView.IContextElement element = wdContext.currentContextElement();
        if(element.get<attibute>!=null){
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(<attribute>);
IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.getModifiableSimpleType();
String filename = binaryType.getFileName();
wdComponentAPI.getMessageManager().reportSuccess("File Name:" filename);
else {
  wdComponentAPI.getMessageManager().reportException("no file",true)
If I am not selecting any file, I am getting the "no file" message.
But after selecting any file and clicking the button, I am getting the below error.
java.lang.NoSuchMethodError:com.sap.engine.services.servlets_jsp.lib.multipart.MultipartMessage.setCharset(Ljava/lang/String;)V
I can understand from SDN that it is because of the version issues.
My Webas is 6.40 SP 17. Initially I had NWDS 2.0.16. Now I have upgraded to 2.0.17. But still I am facing the issue. 
Also in NWDS for default I have j2sdk 1.4.2_09.
The above logic is working fine on server which is on windows. Now I am trying to implement in different server which is on Unix.
I have lots of other projects developed on NDWS 2.0.16 working fine in Unix.
Could you please help me in solving the issue.
Thanks in advance!

Hi Sudhir,
Thanks for the response. As I mentioned, I am working on NWDS 04. So I dont have the option of having value attribute as "Resource".
One additional Info:
I have 2 tabs in my WD view. In one of the tabs I am having the fileupload UI.
After selecting the file when I navigate to next tab, I am getting the same error message.
Any other options or check required for solving the issue.
Regards,
Saravanan
