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 ? Someone
else might be able to help here

Everywhere I have turned so far, has told me to look at the JBoss source

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).

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

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.

 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
 MyApplication app = someway of getting access to the instantiated object;
 Object obj = app.getSomeData();
 If anyone can provide an example for this, I would very much appreciate it.

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 :)

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);

Subject: Embedded tomcat with HTTPS

   Myself and a collegue are currently working on an open source
 application, part of which involves embedding a servlet engine. I have
 through some tutorials and the API docs for tomcat and began development
 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);
 SSLServerSocketFactory serverSocketFactory = new SSLServerSocketFactory();

 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
 https://localhost leaves the browser (MSIE) whirring away for 30 seconds
 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
 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
 would probably be more appropriate. If i was wrong on that descision, you
 have my sincere apologies.

Re: Embedded Tomcat and custom connector ?

2002-07-31 Thread Eriam Schaffter

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.

 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 ?
