hallo,
we have problem with Quartz and Tomcat.
Im using tomcat 5.5
i using 'localhost' to deploy a Spring project on server.
after deploy run Quartz the job once time. this is right.
but after restart tomcat, execute the same jobs twice at the same time.
(project new deploy then no problem, only after tomcat stop->start or
restart, then comming problem)
(2 quartz instanz created and started)
in server.xml i use two<Host> tags 1:<Host name="localhost" ...> 2:<Host
name="XXX.com"...> if i use only one host, for example only<Host
name="XXX.com"...>, then no problem., but by which i can not use interface
of tomcat.
a strange thing: in tomcat management interface i have stoped project, but
even though, in catalina.out can ich see, there is still one quartz job run.
I CANT UNDERSTAND!
I don't know how Quartz works with Spring, but at a guess, I'd say that
you're probably adding/configuring jobs when the app starts, but not
removing them when the app stops.
Thus, for each start (or restart) you're getting an additional job(s).
Probably a question for the Quartz/Spring community, you're more likely
to get accurate answers there - it's unlikely to be anything to do with
Tomcat or its respective config.
p
how can i prevent it?
follow code are our server.xml code
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="false"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
<Host name="XXX.com"
unpackWARs="true" autoDeploy="false" deployOnStartup="false"
xmlValidation="false" xmlNamespaceAware="false">
<Alias>www.XXX.com</Alias>
<Context path=""
docBase="/var/lib/tomcat55/webapps/xxx"
reloadable="true">
<Realm className="org.apache.catalina.realm.JDBCRealm"
driverName="org.postgresql.Driver"
connectionURL="jdbcostgresql://localhost:5432/xxx"
connectionName="postgres" connectionPassword="" userTable="users_password"
userNameCol="userid" userCredCol="password"
userRoleTable="user_role" roleNameCol="rolename"
digest="MD5"/>
</Context>
</Host>
...
follow code are configuration of Quartz in applicationContex.xml
