Re: Moving init params from web.xml to context.xml
from tomcat configuration docs http://tomcat.apache.org/tomcat-7.0-doc/config/context.html You can configure named values that will be made visible to the web application as servlet context initialization parameters by nesting Parameter elements inside this element. For example, you can create an initialization parameter like this: Context ... Parameter name="companyName" value="My Company, Incorporated" override="false"/ ... /Context This is equivalent to the inclusion of the following element in the web application deployment descriptor (/WEB-INF/web.xml): context-param param-namecompanyName/param-name param-valueMy Company, Incorporated/param-value /context-param but does not require modification of the deployment descriptor to customize this value.

That's correct but there's no way afaik to map a context parameter onto a servlet init parameter like these mentioned previously: servlet ... init-param param-nameSERVA_PROPS/param-name param-value/WEB-INF/SERVA.properties/param-value /init-param /servlet In my experience the servlet needs to search both context parameters and init parameters for initialization.

M Thanks Marvin. That is what I was thinking, the two are separate entities, with separate methods of accessing them. Not being a developer, I wasn't positive though.

It's a valuable change that dramatically increases your deployment options; well worth the effort IMO.

One option is to modify your servlets' base class to override getInitParameter (and friends) to also search the context parameters. You could even use a servlet-name prefix for your context-param to avoid collisions. If you don't have a servlet base class... you should :) - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5T+ScACgkQ9CaO5/Lv0PCLfQCguxuL2SjVgquZPtZ69zkB6+lA GbcAn0LHiOTEqvTrTc9T1wuzgOy1SdUF =S2iG -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
