creating ocol-Extensions
Hello, I'm searching for a way to extend Tomcat and let him process some other protocols instead of HTTP. I want to use Tomcat for acting as an Open-Source streaming server. The stream-controlling protocol(RTSP) makes extensive use of the HTTP-specifications, so the idea was to just modify the existing HTTP-Connector to let Tomcat handle the system-level resources like Threads and stuff and to use Servlets as an application interface. Beside this there are some other protocols needed to stream the media to the clients based on UDP. While having some deeper look at the org.apache.catalina.connector classes it seems that they are coupled to HTTP and Coyote. So the first idea seems a bit dirty, cause it would mean to make some deeper changes which was not intended ;) Can anybody please confirm my observations! Kind regards, Florian
Re: Tomcat 6 source organisation part 2
Hi Remy! Ok, so I'll (try to) create the structure (not the one in this mail), but how is it done in SVN ? Is it all simply folders without anything special ? A simple bunch of "svn mkdir" commands will do its job. There's nothing special about it.

Re: Bug report
Hi Dimitri,
this is not a Tomcat bug, but look at the second "rs = stmt.executeQuery();"
You closed this "stmt" few lines before and I think you intended to call
"rs = stmt_jeucode.executeQuery();" instead.
Regards,
Florian

Re: Bug report
Hi Dimitri,
forget this one, I should read the postings completely before responding :-)
So Charly is completely right with his assumption.

Custom compression filters
Dear TC Devs, while looking around in TC 7 I've found no possibility to plug-in a custom compression filter. So I've had a quick look at the code to find out that the gzip-handling is coded into AbstractHttp11Processor. Though I could create a custom processor, I'd like to know whether there's any interest in having the standard processors supporting custom compressions.

Re: Custom compression filters
Thanks for your reply, Konstantin and Jess.The main reason for adding this feature to the Container is the same as for all features provided by a Container:My applications should not deal with these details.Currently I'm looking at adding Googles Snappy to some servers.I could add filters to my applications, but if possible, I'd like to get around this, as I'd have to do it to a bunch of applications,partially running on the same Tomcat or JBoss instances.I'm currently thinking about which way to go.Patching Tomcat was not that hard and it was fun anyway.Maintaining a custom Tomcat codeline is something I'd like to avoid (I've already got a customized installation, but this deals only with configuration and packaging).Maybe Jess is right and a ServletFilter is not that bad, grmbl :-)I've already implemented an initial version. It's not ideal, but it's enough for me to play around: TC70x_1390896_compression_filter.patch Description: Binary data Your feedback is highly appreciated!Best regards,FlorianAm 30.09.2012 um 10:42 schrieb Konstantin Kolinko:2012/9/29 Florian Fray <f...@itcf.biz>:Dear TC Devs,while looking around in TC 7 I've found no possibility to plug-in a custom compression filter.So I've had a quick look at the code to find out that the gzip-handling is coded into AbstractHttp11Processor.Only HTTP protocol management is performed by AbstractHttp11Processor.
