Summary

0004051: Servlet 3.0 Upload API throws NPE

Description

When using Servlet 3.0 API for file upload, I get the following NPE:

<snip>
java.lang.NullPointerException
    at com.caucho.server.http.HttpServletRequestImpl$PartImpl.write(HttpServletRequestImpl.java:2142)
    at org.wiztools.fileupload.ServletIndex.doPost(ServletIndex.java:39)

    at com.caucho.util.ThreadPool$PoolThread.runTasks(ThreadPool.java:901)
    at com.caucho.util.ThreadPool$PoolThread.run(ThreadPool.java:866)
</snip>

This happens only when my Servlet has both doGet() and doPost() method. When I write a Multipart Servlet having only doPost() method, this exception is not thrown.

I have created a sample project to test this issue:

http://code.google.com/p/servlet30-file-upload/ [^]

(Maven based JavaEE 6 Web Project)

Only the third upload feature (*With Additional Parameters to Exclusive Servlet*) in this sample application works.
