[Tried to read the tomcat docs, but it is a bit confusing]
Right, my goal is to deploy war files that get unpacked so that I can see
the directory structure.
I am not interested in autoDeploy or deployOnStartup, unless it is
necessary.
Here is a paragraph from the docs:
"Finally, note that if you are defining contexts explicitly, you should
probably turn off automatic application deployment. Otherwise, your context
will be deployed twice each, and that may cause problems for your app."
So, I guess I am defining contexts explicitly, since I add a context.xml
file under the META-INF
folder of each of my web apps.
This then means that autoDeploy should be set to false of my Host elements.
Also I set deployOnStartup to false since I am not in need of it.
Here is how I do:
1. Create a folder under webapps and name it test so the path is
webapps/test
2. Add this Host element:
<Host name="www.test.com" deployOnStartup="false" debug="0"
appBase="webapps/test" unpackWARs="true" autoDeploy="false"
xmlValidation="false" xmlNamespaceAware="false">
<Valve
className="org.apache.catalina.valves.FastCommonAccessLogValve"
prefix="access_log."
suffix=".txt"
pattern="common"
directory="C:/Program Files/Apache Software Foundation/Tomcat
5.5/webapps/test/logs"/>
</Host>
3. The context.xml under the META-INF folder of the test web app:
<Context>
<Resource
name="jdbc/testDB"
factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
auth="Container"
type="javax.sql.DataSource"
maxActive="10"
maxIdle="5"
maxWait="10000"
removeAbandoned="true"
removeAbandonedTimeout="60"
logAbandoned="true"
username="root"
password="secret"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/test" />
</Context>
4. Deploy the test web app under the webapps/test folder and name the war
file ROOT.war:
webapps/test/ROOT.war
5. Start Tomcat and it works:
It works locally, when Host name is 127.0.0.2 instead of www.test.com,
have not tried yet
on the production server, but I assume it should.
Questions:
1. Some web apps don't need the JNDI/JDBC data source configuration,
is it OK with an empty context element in the context.xml file:
<Context />
2. Is all the configuration above OK (even though it works)
3. My production tomcat server (configured differently, very much the old
fashioned way with Context elements within Host elements) after a while do
not show the websites although the tomcat server is still
running.
Could this be because of misconfiguration?
Nothing else is running on port 80 and the firewall is turned off. The OS is
windows server 2003.
Thanks for all help so far.
