Form Upload throwing null pointer. cannot retrieve the file in
action class..HELP URGENT!!!
Hi,
I have a jsp from which i upload a file. this field is of Formfile type.
jsp entry:
<html:form method="post" enctype="multipart/form-data"
action="/pages/deploy-action.do" >
<td> <html:file name="deploymentForm" property="theFile" /> </td>
<br>
<tr>
<td> <html:submit onclick="upload()" value="Upload the excel" >
</html:submit> </td>
</tr>
</html:form>
I have not used bean:define in the jsp. when i use it,it throws cannot
assign null exception.
in the struts config xml, entries are present for form - bean but not for
its property, i tried entering the property, it did not make a difference
I am using the multiform/form-data enctype and also method=post.
when i run the page and upload the file and invoke the action class i get
the following error.
java.lang.NullPointerException
at actions.DeployAction.execute(DeployAction.java:139)

org.apache.struts.action.RequestProcessor.processActionPerform(Reques

The problem you have is that struts does not instantiate form bean correctly.
If you are using action form object in your case deployForm object , check
if it extends ActionForm.May be it does not and thats why form object is
null.Try this first.
Also, i recommend using DynaActionForm inside struts-config.xml and do not
create objects for form beans yourselves. Struts will automatically do that
for you.

Hi,
try removing the .do from your action in the form and just put the action
name what is in the struts-config.xml.
Thanks,
Nuwan

sorry mate..this is the code that throws the exception
if (actioncalled!=null && actioncalled.equals("upload"))
{
System.out.println("inside upload action");
FormFile myFile = deploymentForm.getTheFile();
}
