Hello,
I am trying to un-deploy a servlet dynamically and it throws an exception:
javax.servlet.UnavailableException: Servlet not initialized

I am using the following code to undeploy:
ServletHandler handler = servletContext.getServletHandler();
//Get all existing servlets.
List<ServletHolder> currentHolders =
Arrays.asList(handler.getServlets());
List<ServletHolder> newHolders = new ArrayList<ServletHolder>();
PathMap.MappedEntry<ServletHolder> entry =
handler.getHolderEntry(servletEndPoint.getContextPath());
ServletHolder obsoleteHolder = entry.getValue();
for(ServletHolder holder : currentHolders)
{
if(!holder.equals(obsoleteHolder))
{
newHolders.add(holder);
}
}
handler.setServlets(newHolders.toArray(new ServletHolder[0]));
Could someone confirm what is the way to undeploy dynamically? I could
deploy dynamically with no issues.
