This shouldn't be too hard to solve. Post the associated servlet and servlet-mapping from your web.xml -the one under webapps/study. On Friday, November 29, 2002, at 05:53 PM, Steve R.

RE: How to add a servlet to a new Webapp
This problem is new with 4.1.12. For security reasons the invoker servlet had been disabled in the global /conf/web.xml file. This invoker servlet usually loads user servlets that are not mapped correctly as far as i understand. This is done by using a default mapping /servlet/*. In productive systems this should not be done, instead correct mapping is required. In the /examples webapp the invoker servlet had been enabled again with the local web.xml. That's why it's working in examples and not in study. Because in your study web.xml you won't have it enabled manually and thus the default from /conf/web.xml ist used where this feature is disabled. Thus the mapping /servlet/... to servlets is just Tomcat specifically done via the invoker servlet which is now (4.1.12+) disabled by default. But actually you should not need /servlet/ at all, if your mapping is correct. Try http://localhost:8080/study/com.wrox.projsp.ch03.Testservlet or make a shorter mapping to /study/Testservlet in your web.xml mech -Original Message- From: Curley, Thomas [mailto:[EMAIL PROTECTED]] Sent: Donnerstag, 28.

RE: How to add a servlet to a new Webapp
Thomas has got a mapping to the invoker servlet in the web.xml file he posted so it should not be a problem. -Original Message- From: mech [mailto:[EMAIL PROTECTED]] Sent: 28 November 2002 13:25 To: 'Tomcat Users List' Subject: RE: How to add a servlet to a new Webapp This problem is new with 4.1.12. For security reasons the invoker servlet had been disabled in the global /conf/web.xml file. This invoker servlet usually loads user servlets that are not mapped correctly as far as i understand. This is done by using a default mapping /servlet/*. In productive systems this should not be done, instead correct mapping is required. In the /examples webapp the invoker servlet had been enabled again with the local web.xml. That's why it's working in examples and not in study.

Re: How to add a servlet to a new Webapp
Thomas, filters are classes that preprocess / postprocess servlet requests. Defining a filter, you are instructing the server to pass the requests to a specified filter, instead of directly passing it to the servlet. Filter is responsible of redirecting the request to the servlet between pre and postprocess. If you remove from your web.xml all filter, and filter-mapping tags, the webapp should still work properly. As some pointed in previous messages, the invoker servlet was disabled in Tomcat 4.1.12. This was done because of a security hole that allowed a hacker to obtain the source code of your JSPs through direct invocation to this servlet. The invoker servlet is the one used for serving requests of the style /servlet/MyServlet. This means that having the invoker servlet disabled you cannot access your servlet with such a URL. But you have an entry in your web.xml that makes the last point irrelevant: servlet servlet-nameTestServlet/servlet-name servlet-classcom.wrox.projsp.ch03.TestServlet/servlet-class /servlet servlet-mapping servlet-nameTestServlet/servlet-name url-pattern/TestServlet/url-pattern /servlet-mapping With these lines you are specifying that you can access your servlet directly with a URL with the form: http://yourserver/study/TestServlet Without the /servlet/ part. URLs with /servlet/ are useful for accesing servlets that don't have an associated mapping, but in your case, as you explicitly mapped it to /TestServlet, you can use this mapping. - Original Message - From: Curley, Thomas [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Thursday, November 28, 2002 3:14 PM Subject: RE: How to add a servlet to a new Webapp Hi, this is now working thanks to you all.

Re: MYSTERY SOLVED: RE: How to add a servlet to a new Webapp
i am having the same problem described in this thread what does this (the proposed solution) mean: The reason is that the invoker servlet is not turned off for the examples. Okay? Check the code and the xml. I am migrating from 4.0.3 to 4.1.12. Thanks, Scott -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

You just have to either turn the invoker servlet back on (with security problems, if it is not yet fixed) or use the standard xml way of getting access to the classes.
