Make sure that whichever JavaScript/DOM construct/property causes the problem is supported by jWebUnit/HtmlUnit. While basic JS is supported, not all DOM methods are available.

Hi,

I have used HttpUnitOptions.setExceptionsThrownOnScriptError( false );
to ignore the exception but it is not working.

Where did you call this method? If I remember correctly, you need to call this method before instantiating your web client object.
