Вам нужно сделать это вручную (вероятно, должен быть удобный метод, но его нет)
В Jetty 7 это будет что-то вроде ( не проверено ):
public void removeServlets(WebAppContext webAppContext, Class<?> servlet)
{
ServletHandler handler = webAppContext.getServletHandler();
/* A list of all the servlets that don't implement the class 'servlet',
(i.e. They should be kept in the context */
List<ServletHolder> servlets = new ArrayList<ServletHolder>();
/* The names all the servlets that we remove so we can drop the mappings too */
Set<String> names = new HashSet<String>();
for( ServletHolder holder : handler.getServlets() )
{
/* If it is the class we want to remove, then just keep track of its name */
if(servlet.isInstance(holder.getServlet()))
{
names.add(holder.getName());
}
else /* We keep it */
{
servlets.add(holder);
}
}
List<ServletMapping> mappings = new ArrayList<ServletMapping>();
for( ServletMapping mapping : handler.getServletMappings() )
{
/* Only keep the mappings that didn't point to one of the servlets we removed */
if(!names.contains(mapping.getServletName()))
{
mappings.add(mapping);
}
}
/* Set the new configuration for the mappings and the servlets */
handler.setServletMappings( mappings.toArray(new ServletMapping[0]) );
handler.setServlets( servlets.toArray(new ServletHolder[0]) );
}
