[Htmlunit-user] Exception when using Page.submit()

[Gian F. C. <gia...@to...>]

Hi,

I've written some code in a jsp page that
calls some java code that uses HtmlUnit to
connect to a web site.

The java code works correctly when I use it
in isolation as a java application.

Problems arise with the above mentioned jsp
page. When the code is running I get a long
list with the same message:

---------------list begin---------------
    ...
    [26-10-04 8:54:20:914 CEST] 5dc773e1 HttpMethodBas W
    org.apache.commons.httpclient.HttpMethodBase
    Response content length is not known

    org.apache.commons.httpclient.HttpMethodBase
    Response content length is not known
    ...
---------------list end---------------

This continues for a long time, until I get the message:

---------------list begin---------------
JVMDG315: JVM Requesting Heap dump file
...JVMDG318: Heap dump file written to E:\Program Files\IBM\WebSphere...
JVMDG303: JVM Requesting Java core file
JVMDG304: Java core file written to E:\Program Files\IBM\WebSphere\...
JVMDG215: Dump Handler has Processed Outofmemory Signal -1.
---------------list end---------------

A printStackTrace() shows the following:

---------------list begin---------------
    com.gargoylesoftware.htmlunit.ObjectInstantiationException:

Can anyone help me with this?
