Thank you. I believe I understand your problem better.
Following is the getRequestDispatcher method of the AbstractHttpServletRequestWrapper:
public RequestDispatcher getRequestDispatcher(String thePath)
{
if (thePath == null)
{
return null;
}
RequestDispatcher dispatcher = null;
String fullPath;
if (thePath.startsWith("/"))
{
fullPath = thePath;
}
else
{
String pI = getPathInfo();
if (pI == null)
{
fullPath = catPath(getServletPath(), thePath);
}
else
{
fullPath = catPath(getServletPath() + pI, thePath);
}
if (fullPath == null)
{
return null;
}
}
LOGGER.debug("Computed full path : [" + fullPath + "]");
dispatcher = new RequestDispatcherWrapper(
this.request.getRequestDispatcher(fullPath));
return dispatcher;
}
Your case can be occured if
this.request.getRequestDispatcher(fullPath)
returns null because null-check for the originalDispatcher is not taken
in the constructor of the RequestDispatcherWrapper.
Here, this.request should be a HttpServletRequest instance
given from your container.
For fullPath value, please follow the logic of the code above.
Is the fullPath value computed from your command.execute() result,
which is given as the argument thePath, valid for your container?
You can also logging the real fullPath value.
