Web Service security with Apache Axis. 403 forbidden error

Question

Hello.
I have to invoke a Web Service method via https. To achieve that, I have correctly added the server certificate to my truststore.
When I invoke the method, I obtain this error:
AxisFault
faultCode: {http://xml.apache.org/axis/}HTTP
faultSubcode:
faultString: (403)Forbidden
This is because the server requests me for a client certificate.
I have the certificate, but I don't know how to use it in the java client.
Does anybody know how to do that? Any kind of help will be very useful.
Thank you very much in advance.
NOTE: If I write the url of the web service in a web browser, the server requests me for a client cert. When I chose the appropiate certficate, the web browser shows me this message from the web service: "Hello, this is a Web Service"

Finally my problem has been solved.
I added the necesary properties to the system and everything went well.
This is the code:
String trustStore = System.getProperty("java.home") + "/lib/security/cacerts".replace('/', File.separatorChar);
String keyStore = System.getProperty("java.home") + "/lib/security/keystorePKCS12".replace('/', File.separatorChar);
String tspasswd = "myTrustStorePassword";
String kspasswd = "myKeyStorePassword";
System.setProperty("javax.net.ssl.trustStore", trustStore);
System.setProperty("javax.net.ssl.trustStorePassword", tspasswd );
System.setProperty("javax.net.ssl.keyStore", keyStore);
System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
System.setProperty("javax.net.ssl.keyStorePassword", kspasswd );It's necesary to say that my keystore is PKCS12 type, and it stores only one pkcs certificate.
Note that is also posible to set these system properties in the Tomcat start script.
