Tomcat 5.5.16 seems to call a servlet's init() method several times, and
the specific init parameter is missing in all but the first.
I have a simple server.xml that includes:
<Host name="www.example.com" appBase="/var/web/apps"
unpackWARs="false" autoDeploy="false"
xmlValidation="false" xmlNamespaceAware="false">
<Alias>example.com</Alias>
<Context path="" docBase="www.example.com.war">
<Parameter name="dataDirectory"
value="/var/web/data/www.example.com/"/>
</Context>
</Host>
In www.example.com.war I have a web.xml file that includes two instances
of MyServlet, with servlet names of myServlet1 and myServlet2, mapped to
"/*" and "/example/*", respectively.
Tomcat does the following, which I find odd:
1. myServlet1.init() is called. The init parameter "dataDirectory" is
correctly set to "/var/web/data/www.example.com/".
2. catalina.out indicates "Jun 25, 2006 2:07:26 PM
org.apache.catalina.startup.HostConfig deployWAR".
3. myServlet.init is called(). The init parameter "dataDirectory"
returns null.
4. myServlet2.init is called(). The init parameter "dataDirectory"
returns null.
(Then steps 3 and 4 are repeated, presumably because steps 2 and 3 throw
NullPointerExceptions, which results from the missing init parameter.)
This confuses me:
* Why is myServlet1.init() called twice?
* Why isn't myServlet2.init() called before the second call to
myServlet1.init()?
* Why is the init parameter "dataDirectory" only available in the first
call to myServlet1.init()?
Thanks for any insight,
Garret
