Next time, just post them separately. > 1st issue: I cannot connect to a socket server embedded in a webapp and > listening on port 10000 any more in all cases.

Hmm... so, on the Linux install, mobile devices (presumably through the wireless provider's network) connect correctly, but non-mobile devices fail? This sounds like it might be a firewall issue. Does your laptop allow outgoing connections to port 10000? How about your router? Are you on a corporate network with IT Nazis preventing you from doing anything but using ports 80 and 443? You can use traceroute or other tools to confirm connectivity independently of the server software. Telnet also helps, sometimes, too. > 2nd issue: mod_jk does not work.

Most often, I've seen configurations where the JkWorkersFile directive is in the wrong place. Also, please post as much error information as mod_jk provides in your mod_jk.log file. > 3rd issue: GWT-RPC calls do not get delivered any more to the browser on my > laptop.

Tomcat looks like it's expecting to receive requests from httpd via AJP (provided by mod_jk). > tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN > > 29931/jsvc Also good: Tomcat is listening to port 10000. This means that your Tomcat configuration appears to be correct in terms of SecurityManager (if present), socket binding rights, etc. > tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN > > 29931/jsvc Note that Tomcat is also listening to port 8080, which is the default HTTP port in server.xml. If you don't want connections to circumvent httpd, you might want to disable this connector. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktgjyEACgkQ9CaO5/Lv0PCO3ACfU1bRXkSPB6Ra3WiepoMMmdUN V1wAoJuA6cOFHCG1EQnBxH9Ex30ADjMM =XGBZ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
