I'm trying to configure tomcat to work https port 8443.

using tomcat 7.

I enabled the https connectors with the following parameters:

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" keystorePass="<pass>"
           maxThreads="150" scheme="https" secure="true" keystoreFile="${catalina.base}/foo/bar.keystore"
           clientAuth="false" sslProtocol="TLS" />

I created a keystore with the password and the domain required.

when I start tomcat and browse for the admin panel or for my jsp page using port 8443 i get scrumbled unidentified data. which means that i get https encrypted data passed over http. when i browse on port 8080 i see it properly. what am I missing ?

thank you!



I have this configuration in server.xml

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

and I have this in the log:

May 02, 2013 5:57:45 AM org.apache.catalina.core.AprLifecycleListener init
INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/package

so maybe this is the problem.

it's just an INFO so I ignored it. but maybe because of missing APR the SSLEngine is not working.

I have gentoo linux and I have the APR package installed I have no idea why it doesn't detect it.

  • Are the Certificates self signed? Does the browser give any indication that the connection is https?

  • the cert is self signed and the browser doesn't give any indication that it's https

It doesn't look like you have misconfigured anything. However, you may need to explicitly specify the protocol in your URL as well as the port, eg. https://your.server:8443. Most applications (browsers etc.) will infer HTTP if the port isn't 443 and HTTPS isn't specified.

Try also explicitly specifying http:// in the URL in your browser, just to see if it renders. I would be surprised, though; it looks like you've enabled TLS correctly.

The lack of the tomcat native library is not the cause.

  • Not the port, but the protocol. I'm sure you got the port. May 2, 2013 at 6:07
