2009 News & Status
22 March - JK-1.2.28 released
The Apache Tomcat team is proud to announce the immediate
availability of Tomcat Connectors 1.2.28. This is a stable
release concentrating mainly on some bug fixes.
Please see the ChangeLog for a full list of changes.
If you find any bugs while using this release, please fill
in the Bugzilla Bug Report.
The most important new features in this version are:
Better Error Detection for Load Balancer Workers
Local and global error states have been improved. You can
fine tune the behaviour with the new
"error_escalation_time" attribute (see the timeouts
documentation).
Dynamic Address and Port Change Using the Status Worker
The status worker now allows you to change the address and
the port of an AJP13 worker on the fly. You can e.g.
provision dummy workers with a port equal to "0", which
will be automatically put into stopped mode during
startup. Later, when you want to actually use thse
workers, you set their address and port to the final
values.
Note that already existing connections will go on using
the old address and port. This will be improved in future
versions.
New Data in Status Worker Display
The status worker display now also contains the timestamp
of the last worker errors.
Improved Proxy Flexibility
You can now overwrite more request metadata before the
request gets send to the backend. This is helpful in case
there are other reverse proxies in front of your web
server. A new documentation page explains this in detail.
Improved IIS Support
IIS support has been improved especially when using
mutltiple application pools. Furthermore you can now
configure the ISAPI plugin to update the
uriworkermap.properies file on a regular interval using
the watchdog thread.
JNI Worker Deprecation
Workers of type jni are broken since a long time. Since
there is no more use for them, they have been deprecated
now, and will be removed in a future release.

The Apache Tomcat Connector - News *
2008 News and Status
2008 News & Status
28 October - JK-1.2.27 released
The Apache Tomcat team is proud to announce the immediate
availability of Tomcat Connectors 1.2.27. This is a stable
release adding lots of new features and some bug fixes.
Please see the ChangeLog for a full list of changes.
If you find any bugs while using this release, please fill
in the Bugzilla Bug Report.
The most important new features in this version are:
Watchdog Thread for Periodic Tasks
The connector has to run some periodic tasks independant
of request processing. Examples are probing or closing
down idle backend connections, adjusting load numbers and
recovering workers from error state.
Before version 1.2.27 these tasks were done inside the
request processing loop. When a new request came in and
the task was due, the thread handling the request first
executed the internal task and then handled the request.
If there were no requests coming in, the tasks would not
run. If any of the tasks took unexpectedly long, the
response time of the request waiting for the finishing of
the task went up.
Starting with this release you can configure a separate
watchdog thread inside the web server to run all those
tasks independantly of request processing. This new
feature is avaliable for the connector when used with
Apache httpd 2.x or with Microsoft IIS. To keep the
behaviour of the new version consistent with previous
releases, this feature is turned off by default. You can
activate the watchdog thread via JkWatchdogInterval for
Apache or watchdog_interval for IIS.
Connection Probing
In previous releases connection probing (checking whether
connections still work) could only be done immediately
after a new connection was established and directly before
sending each request. Since we now have the watchdog
thread available, we also added a periodic probing option,
which you can activate with the worker attribute ping_mode
. This will also be useful as a protection against the
infamous firewall idle connection drop.
The older attributes connect_timeout and prepost_timeout
still exist and work the same way they did in previous
releases. Since there are now three different probing
options, we recommend to migrate your configuration to the
newer attributes ping_mode, ping_timeout and
connection_ping_interval.
Mount Extensions
Usually one defines workers and mounts for the connector.
A worker defines a backend we want to talk to and the
configuration parameters of the communication, connection
pools etc. The mounts define which URIs we want to forward
to which worker (so we also call a mount an URI map rule).
In version 1.2.27 you can overwrite certain worker
parameter per mount.
One easy to understand example is reply timeouts. Until
this release you had to specify a reply timeout for the
whole worker. But reply times depend a lot on the type of
request. So normally you want to define a general reply
timeout and for some special URLs you need to relax the
reply timeout, because you know those URLs take much
longer to process (like e.g. reporting or other compute
intensive tasks).
Another possible case is the activation status. You might
use a load balancer worker to forward requests to certain
webapps in a farm of Tomcat nodes. If you wanted to update
some webapp on one node, you previously had to stop
forwarding requests for all webapps on this Tomcat node.
What was not possible until now, was stopping forwarding
requests restricted to the webapp and the node you wanted
to update.
Starting with this release, you can add so-called rule
extensions to your uriworkermap file to influence worker
parameters per mount. This will work for all Apache
versions and for IIS. Remember, that the uriworkermap file
automatically gets reloaded after changes without web
server restart.
Improved IIS support
We improved IIS support im various ways. It is now
possible to use multiple IIS 6 application pools with the
ISAPI redirector.
Furthermore some improvements were added as compile time
features. The most notable one is chunked encoding
support, which was a major refactoring and is therefore
still considered experimental. You can download binaries
with and without chunked encoding support. In future
versions, chunked encoding will likely be availabe in all
builds.
Another new feature is an elegant way of configuring error
page redirects. All new features are documented on the
documentation page about configuring IIS.
Enhanced Status Worker
The status worker now can also manage and show statistics
for AJP workers that are not part of a load balancer.
Other improvements are the new dump action, the
integration of the new configuration attributes, showing
average request and transfer rates since the last
statistics reset and the ability to display only a single
member of a load balancer.
Unfortunately we had to change some request parameters
used for the update action of the status worker.
Miscellaneous Improvements
Further enhancements are:
+ Configurable session stickyness indicator: cookie name
and URL path parameter name can be freely chosen
instead of the servlet spec compliant JSESSIONID and ;
jsessionid.
+ Automatically determining the size of the shared
memory segment needed to accommodate all workers.
+ New connection establishment timeout
socket_connect_timeout.
+ New timeout connection_acquire_timeout for acquiring a
free connection from the pool.
+ Improved retry handling by adjusting the meaning of
the attribute retries for AJP workers and for load
balancers and by adding the new retry_interval.
+ Allowing the web server to provide error pages instead
of Tomcat.

15 November - JK2 is officially unsupported
JK2 has been put in maintainer mode and no further
development will take place. The reason for shutting down
JK2 development was the lack of developers interest. Other
reason was lack of users interest in adopting JK2, caused
by configuration complexity when compared to JK.
The latest official JK2 release is 2.0.4.
JK2 will have it's successor within core Apache2.1/2.2
distribution. We have developed new proxy_ajp that is an
addition to the mod_proxy and uses Tomcat's AJP protocol
stack. It is developped in httpd-2.1 and integrated in it.
We have also developed a new proxy_balancer module for
load balancing http and ajp protocol stacks.
JK will be fully supported for all other web servers. The
next JK release is planned for the end of November. Lots
of code from JK2 has been ported to JK
