Tomcat Server.xml maxAge "unknown property"

[Quincy Schmidt]

Hoping someone can tell me what I am missing with this.  I added maxAge to the resource name for 100 minutes as seen below; but the log file comes back with:

catalina.out
o.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory - Name = RadiusDataSource Ignoring unknown property: value of "600000" for "maxAge" property

server.xml

<Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml"/>
<Resource name="com/server/jdbc/RadiusDataSource" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" connectionProperties="includeSynonyms=true" url="jdbc:oracle:thin:@oracle:1521:servicename" username="user" password="pwd" maxActive="25" maxIdle="8" maxAge="600000"/>

I have also tried max-age max-Age and different values. "60" "600" "6000" etc etc.

Which version of Tomcat?

Here's an easier to read formatted version of your config:<Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> <Resource name="com/server/jdbc/RadiusDataSource" auth="Container" type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver" connectionProperties="includeSynonyms=true" url="jdbc:oracle:thin:@oracle:1521:servicename" username="user" password="pwd" maxActive="25" maxIdle="8" maxAge="600000" />

maxAge is simply not a valid attribute for a Resource. Don't know what else to tell you. Where did you get the notion of this attribute?

Tomcat uses plug-replaceable DBCP Connection Pool modules and they changed which one came pre-installed somewhere around Tomcat 8.

The Resource element defines a JavaBean that produces javax.sql.Datasource objects. Tomcat's XML is fluid, so there's no schema for it, and in particular, there's no standard definition for a Connection Pool bean. Instead, the Digester takes the Resource attributes and attempts to apply them as properties to the Connection Pool bean object.

In other words, the particular Connecton Pool class that is being used here doesn't have a "setMaxAge()" method that the Digester can use to inject an age value into the pool object.

If this was a critical function, I'd recommend looking for an alternative Connection Pool to plug in, but really, it's best to just not define maxAge in the Resource. It won't be missed.

Oh, incidentally, com/server/jdbc/RadiusDataSource is a pretty awful JNDI name. Most of us would simply call it jdbc/RadiusDataSource and look it up as java:comp/env/jdbc/RadiusDataSource
