Sorry, new to Nabble.
I am defining a servlet filter.
I tried to use the existing wars built for Tomcat 5.0.28, but they would not
deploy at all. So, yes, I rebuilt them for Tomcat 5.5.28.
You should rebuild, especially if you are compiling JSPs.
Yes, I have a servlet-api.jar in the WEB-INF/lib/ and tomcat/common/lib
directories.
That'll be a problem. Don't put it in WEB-INF/lib.
Eclipse (really MyEclipse) automatically builds the war with
the jar, based on the project build path. I removed the servlet-api.jar
from the WEB-INF/lib and started the server again---got the following error:
SEVERE: Exception starting filter sitemesh
java.lang.NoClassDefFoundError: javax/servlet/Filter
at java.lang.ClassLoader.defineClass1(Native Method)
Tomcat supplies all of the servlet & JSPs jars, you don't need to add them.
With the servlet-api.jar in WEB-INF/lib/ I get the following error--which is
my original error that I posted:
SEVERE: Exception starting filter sitemesh
java.lang.ClassCastException:
com.opensymphony.module.sitemesh.filter.PageFilter
As above, this is incorrect and will cause problems.
I listed jasper.jar as being an issue.
Why? If it's also duplicated in WEB-INF, then it should not be.
It was naming-*.jars packaged with Tomcat 5.5.28 that was an issue.
Again, why. No duplication allowed as above.
Also, I had a references to older jars
(such as jstl.jar) in my project--Tomcat 5.5.28 uses newer jars for several
things.
Tomcat 5.5 doesn't know JSTL exists, you must supply it if you are using it.
Classes should only exist in one place in the classloader tree. You may
not duplicate any class in WEB-INF that is supplied with Tomcat, in
tomcat/lib.
Yes, the class definitions in the web.xml are correct....as they are when it
runs on Tomcat 5.0.28.
I orginally stated that the WikiUrlSessionIdFilter was a direct plug in
class. That was not correct--it is referenced and used within our
agriStatsUtilities.jar. The sitemesh class is a direct plug in class.
Following is the web.xml:
You might consider (backing up, then) removing all of the comments from
your active server.xml. Much easier to read.

also modified the standard context.xml to include a DefaultContext for our

You can also enable an SSL HTTP/1.1 Connector on port 8443 by

instructions):
* If your JDK version 1.3 or prior, download and install JSSE 1.0.2

later, and put the JAR files into "$JAVA_HOME/jre/lib/ext".
* Execute:

For a similar mechanism that is portable to all Servlet 2.4
containers, check out the "RequestDumperFilter" Filter in the
example application (the source for this filter may be found in
"$CATALINA_HOME/webapps/examples/WEB-INF/classes/filters").
Note that this Valve uses the platform's default character
encoding.
This may cause problems for developers in another encoding, e.g.
UTF-8. Use the RequestDumperFilter instead.
Also note that enabling this Valve will write a ton of stuff to
your
logs. They are likely to grow quite large. This extensive log
writing
will definitely slow down your server.

<!-- Defines a cluster for this node,
By defining this element, means that every manager will be
changed.
So when running a cluster, only make sure that you have webapps
in there
that need to be clustered and remove the other ones.
A cluster has the following parameters:
className = the fully qualified name of the cluster class
clusterName = a descriptive name for your cluster, can be
anything
mcastAddr = the multicast address, has to be the same for all
the nodes
mcastPort = the multicast port, has to be the same for all the
nodes
mcastBindAddress = bind the multicast socket to a specific
address
mcastTTL = the multicast TTL if you want to limit your
broadcast
mcastSoTimeout = the multicast readtimeout
mcastFrequency = the number of milliseconds in between sending
a "I'm alive" heartbeat
mcastDropTime = the number a milliseconds before a node is
considered "dead" if no heartbeat is received
tcpThreadCount = the number of threads to handle incoming
replication requests, optimal would be the same amount of threads as nodes
tcpListenAddress = the listen address (bind address) for TCP
cluster request on this host,
in case of multiple ethernet cards.
auto means that address becomes
InetAddress.getLocalHost().getHostAddress()
tcpListenPort = the tcp listen port
tcpSelectorTimeout = the timeout (ms) for the Selector.select()
method in case the OS
has a wakup bug in java.nio. Set to 0 for
no timeout
printToScreen = true means that managers will also print to
std.out
expireSessionsOnShutdown = true means that
useDirtyFlag = true means that we only replicate a session
after setAttribute,removeAttribute has been called.
false means to replicate the session after each
request.
false means that replication would work for the
following piece of code: (only for SimpleTcpReplicationManager)
<%
HashMap map =
(HashMap)session.getAttribute("map");
map.put("key","value");
%>
replicationMode = can be either 'pooled', 'synchronous' or
'asynchronous'.
* Pooled means that the replication happens
using several sockets in a synchronous way. Ie, the data gets replicated,
then the request return. This is the same as the 'synchronous' setting
except it uses a pool of sockets, hence it is multithreaded. This is the
fastest and safest configuration. To use this, also increase the nr of tcp
threads that you have dealing with replication.
* Synchronous means that the thread that
executes the request, is also the
thread the replicates the data to the other
nodes, and will not return until all
nodes have received the information.
* Asynchronous means that there is a specific
'sender' thread for each cluster node,
so the request thread will queue the
replication request into a "smart" queue,
and then return to the client.
The "smart" queue is a queue where when a
session is added to the queue, and the same session
already exists in the queue from a previous
request, that session will be replaced
in the queue instead of replicating two
requests. This almost never happens, unless there is a
large network delay.
-->
<!--
When configuring for clustering, you also add in a valve to
catch all the requests
coming in, at the end of the request, the session may or may not
be replicated.
A session is replicated if and only if all the conditions are
met:
1. useDirtyFlag is true or setAttribute or removeAttribute has
been called AND
2. a session exists (has been created)
3. the request is not trapped by the "filter" attribute
The filter attribute is to filter out requests that could not
modify the session,
hence we don't replicate the session after the end of this
request.
The filter is negative, ie, anything you put in the filter, you
mean to filter out,
ie, no replication will be done on requests that match one of
the filters.
The filter attribute is delimited by ;, so you can't escape out
; even if you wanted to.
filter=".*\.gif;.*\.js;" means that we will not replicate the
session after requests with the URI
ending with .gif and .js are intercepted.
The deployer element can be used to deploy apps cluster wide.
Currently the deployment only deploys/undeploys to working
members in the cluster
so no WARs are copied upons startup of a broken node.
The deployer watches a directory (watchDir) for WAR files when
watchEnabled="true"
When a new war file is added the war gets deployed to the local
instance,
and then deployed to the other instances in the cluster.
When a war file is deleted from the watchDir the war is
undeployed locally
and cluster wide
