However, all the examples I've seen show how to load a WAR file and use that as a web application. If it's possible, I'd rather just have a sevlet class inside my program that Tomcat uses rather than having an external web application. You should be able to get away with just a single external file: a web.xml file that mounts the servlet and maps it to a URI pattern. The rest of the webapp code (ie the servlet class you mentioned) would be able to be inside the main jar, because class loader inheritance would cause the servlet class to be visible even if it's not in the WEB-INF/classes folder. If one external file is too many, you might need to do something tricky to set the webapp's mounted instances from code. Maybe via JMX ?

Re: embedded tomcat and JMX sample code
Mark W. Webb wrote: I am looking for some sample code that will demonstrate how to embed tomcat in a java application using JMX. I would like to write some documentation on how to do this, as there is none that exists that I have found on tomcat's web site. I would imagine that there must be some code somewhere that was used for testing the new infrastructure. Everywhere I have turned so far, has told me to look at the JBoss source code, but I figure that the tomcat development team must have some code laying around that will demonstrate this. The Ant script in the embed distribution can directly be translated into JMX commands. Other than that, we have no Java JMX code (so look in the JBoss/Tomcat integration for that).

Re: Embedded Tomcat
Hi Robert,
Congratulations on having Embedded Tomcat in your application.
My apologies for not explaining a solution to your problem more clearly.
The method we had discussed by private mail earlier today indeed works. I
cannot give you actual source code, simply because I'm downloading Tomcat at
the moment.
The only part that you need to work on is the :
MyApplication app = someway of getting access to the instantiated object;
that you have mentioned below:
Let's say your application (with all its parts) is represented by
MyApplication.
You could create the class along the lines of :
public class MyApplication{
private static MyApplication currentInstance = null;
private MyApplication(){
}
public MyApplication getCurrentInstance(){
if (currentInstance==null){
currentInstance = new MyApplication();
initialize(); // some initialization work
}
return currentInstance;
}
}
You should now be able to access MyApplication's object from within your web
applications via MyApplication.getCurrentInstance();
In your care, you do not need JNDI. There is another means of sharing objects
(via JMX) that I shall explore once this Tomcat download is completed.

ServletContext.setAttribute() and ServletContext.getAttribute()
Is there a code example both application side and web side somewhere that
could show me how to do this? I've been wrestling with this for a while and
it's starting to irritate me. :)
I've embedded Tomcat for the sole purpose of being able to create JSPs and
Servlets that can examine the properties of the application and modify the
properties as well. For example, I need to be able to do the following in my
JSP.
MyApplication app = someway of getting access to the instantiated object;
Object obj = app.getSomeData();
obj.modifyInSomeWay();
app.setSomeData(obj);
If anyone can provide an example for this, I would very much appreciate it.
Thanks.

Re: Embedded Tomcat startup java class
Mark W. Webb wrote: Knowing that Tomcat is moving towards JMX, I was wondering if anyone has ported Embedded.java into the a format that will support the JMX integration. Knowing that there is a build.xml file that will launch tomcat in an embedded state, is there an equivalent .java file for doing this? You don't have to do that. You can use Embedded to create your TC instance, and then use JMX to create or destroy contexts. Or use a standalone TC with a server.xml, and use JMX (or Embedded) to manage the contexts (that's how it works in the integrated JBoss 3.2 / TC 5). You can mix and use whatever seems best to you :) Remy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Embedded tomcat with HTTPS
I'm going to assume that you're using 4.1.x. In this case, you are using the wrong Factory. You want something like: Connector httpsConnector = embeddedTomcat.createConnector(null, configuration.getHttpsPort(), true); CoyoteServerSocketFactory serverSocketFactory = (CoyoteServerSocketFactory)httpsConnector.getFactory(); serverSocketFactory.setKeystoreFile(configuration.getKeystoreFile()); serverSocketFactory.setKeystorePass(antares); - Original Message - From: Wesley Hall [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, August 10, 2003 1:23 PM Subject: Embedded tomcat with HTTPS Hello, Myself and a collegue are currently working on an open source application, part of which involves embedding a servlet engine. I have read through some tutorials and the API docs for tomcat and began development of a class structure to provide this. I have, however come across a problem with my https connector. I currently have code that looks like this.. Connector httpsConnector = embeddedTomcat.createConnector(null, configuration.getHttpsPort(), true); httpsConnector.setScheme(https); SSLServerSocketFactory serverSocketFactory = new SSLServerSocketFactory(); serverSocketFactory.setKeystoreFile(configuration.getKeystoreFile()); serverSocketFactory.setKeystorePass(antares); httpsConnector.setFactory(serverSocketFactory); embeddedTomcat.addConnector(httpsConnector); connectors.add(httpsConnector); configuration is a instance of a simple bean, getHttpsPort() returns 443, getKeystoreFile() returns the path to the keystore (generated as per the SSL-Howto doc). The location of the keystore is validated elsewhere in the code using a File object and a call to .isFile() and .canRead(), both of which return true when running this code. However... i am finding that although http://localhost:443 works perfectly, https://localhost leaves the browser (MSIE) whirring away for 30 seconds or so before displaying 'cannot find server'. With the former i get plenty of information in the logs but the latter adds nothing at all to the logs, making this problem very difficult to debug. I can change the keystore pass to any value and there is no appreciable difference. Im happy to provide any more information as required... Would a kind sameritan type point me in the write direction as to what may be causing this issue? Regards Wesley I. Hall. P.S. I thought long and hard on whether this belonged on dev or user, but since we are discussing actually class structure i finally decided that dev would probably be more appropriate. If i was wrong on that descision, you have my sincere apologies. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] This message is intended only for the use of the person(s) listed above as the intended recipient(s), and may contain information that is PRIVILEGED and CONFIDENTIAL.

Re: Embedded Tomcat and custom connector ?
Hi back That was not so clear. What I would like to do is to get *all* http requests and manage them trough another connector then the one that passes them to the filesystem. Example: a http request comes and it's a GET /Test instead of trying to fetch the local Test directory I want to redirect this to another resource like a sql procedure or something else. I think that it's possible to do this by creating the connector by myself instead of creating it on the high level with createConnector method of the Embedded class. Something like creating a HttpConnector with an associated EventHanlder ? Any tips ? Any idea ? Thanks in advance. Eriam Eriam Schaffter wrote: Hi all. I'm embedding tomcat in a java app using the Embedded class. What I would like to do know is to use the http connector but I would instantiate it by my own and not via the createConnector method so I handle requests and responses in my program. The goal is to have a connector that handles http request a bit differently then the one in tomcat (redirect get request on another resource). Any suggestions ?
