Rép. : Executing custom action on d eploy
In your web.xml file, declare a servlet like this :
servlet
servlet-namemyServlet/servlet-name
servlet-classxx.xx.xx.myServlet/servlet-class
load-on-startup1/load-on-startup
/servlet
And in your servlet, the init() method is called when the server start :
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class myServletextends HttpServlet
{
/** Init */
public void init(ServletConfig config) throws ServletException
{
super.init(config);
// do your action
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
// ...
}
}

Hi!
I'm writing a web application for tomcat and I have a strange request:
I would like to execute an initializing function in order to
initialize correctly my applicaiton when it becomes available
(deployed into tomcat or tomcat itself is started)
I have written such behaviour in a method, so what can I do to execute it?
Thanks for your help, Matteo

Re: Rép. : SSL question
If you want use javax.net.ssl you must have tomcat in a version upper or egal
to 5.

Hi, thanks!
I've got my own TrustManager/HostnameVerifier and it works when I use Apache's
SecureWebServer and SecureXmlRpcClient. I'm not using javax.net.ssl, but
instead com.sun.net.ssl - couldn't make it work with javax.net.ssl. Is the code
below necessary for the servlet as well? Thought Tomcat has got all the
information about trusted certificates in its keystore.

You must use :
- your own TrustManager (implements javax.net.ssl.X509TrustManager)
- your own KeyManager (implements javax.net.ssl.X509KeyManager)
- your own HostnameVerifer(implements javax.net.ssl.HostnameVerifer)
and use this following code :
TrustManager[] objTrustManager = new TrustManager[] {new
MyX509TrustManager()};
KeyManager[] objKeyManager = new KeyManager[] {new MyX509KeyManager()};
SSLContext sc = SSLContext.getInstance(SSL);
sc.init(objKeyManager, objTrustManager, new SecureRandom());
SSLSocketFactory objSocketFactory = sc.getSocketFactory();
HttpsURLConnection.setDefaultSSLSocketFactory(objSocketFactory);
HttpsURLConnection.setDefaultHostnameVerifier(new MyHostnameVerifer());
...
URL objUrl = new URL(...)
HttpsURLConnection objHttpsURLConnection =
(javax.net.ssl.HttpsURLConnection) objUrl.openConnection();
I hope it's help you.

Hi
I've got a servlet which works fine when using http. But when I want to
access
it through https I get a certificate unknown exception. Why does
https://localhost:8443 work in a browser but accessing my servlet (with java
client) not? Do I need to make my servlet SSL aware? Using another secure
webserver works with my client. Hope someone can help.
Thanks!

Rép. : Re: How show CLIENT-CERT Rea lm
Thanks. Like I've found nothing, I'm choosing a solution like this. So it is impossible to show CLIENT-CERT realm like response.setHeader(WWW-Authenticate, CLIENT-CERT realm=\myName\); I've an another question : how to redirect an request to the secure port within a serlvet ?

Thanks It is done in o.a.c.authenticator.AuthenticatorBase and the process is basically issue a redirect to SSL. You will need to set the clientAuth attribute on the connector to true to require all connections to present a client certificate.

So I want to basically redirect my request to SSL. I wish know how to redirect a request to the secure port within a serlvet but I don't want use init-parameter in the web.xml and so one. Thanks
