I'd firstly RIC| like to RIC| know why this is. This is a long story. The SSI Servlet calls a servlet by asking the context for a servlet with the given name: Servlet servlet = context.getServlet(className); The context returns an instance of the servlet. The service() method is called - done. If the Servlet is a SingleThreadModel Servlet, the Servlet engine has to make sure, that the servlet()-method of a given instance is called in only _one_ thread. Internally, the engine could do this in differnet ways, usually by maintaining a set of instantiated servlets in a pool. If a servlet is called, it is taken from the pool, executed and put back in the pool. BUT - this is done internally and implementation dependant, and there is no way for a 'user'-servlet (which the SSI-servlet is), to savely get a servlet and put it back. In case of JServ, if context.getServlet() is called, the engine returns an instance which would be save to call, but since there is no way to give it back to the internal pool, this works only until the maximum of STM-instances is allocated (default is 10 AFAIK) ... So - there are several options: Write the servlet thread save (which is the best way IMO). Wait for JSKD 2.1 and an JSSI using it, since there are much better possibilities to call servlets from user servlet IIRC. Or use a solution you proposed - making the SSI servlet STM (a bit hacky). (please read <http://java.apache.org/faq/?file=165> as well !) RIC| And Secondly could I write a servlet which reads in the RIC| .jhtml file RIC| and somehow pass it to the JServSSI Servlet which will replace the RIC| <SERVLET></SERVLET> tag RIC| and subsequently send the result back to a browser ? This can then implement RIC| the SingleThreadModel RIC| interface. Have a look at the PageParserServlet, it uses class PageParser which could be used in your won servlets. You could as well extend the SSI-Servlet and just add the tagging SingleThreadModel interface, something like ----- public class STMSSI extends org.apache.servlet.ssi.SSI implements SingleThreadModel { } ---- ciao, -hen --- Henner Zeller [EMAIL PROTECTED] PGP pub key [77F75B39]: finger [EMAIL PROTECTED] -- -------------------------------------------------------------- Please read the FAQ! <http://java.apache.org/faq/> To subscribe: [EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED] Archives and Other: <http://java.apache.org/main/mail.html> Problems?: [EMAIL PROTECTED]
