JNDI configuration in webapp/META-INF/context.xml

Hi all,

I have tried setting up JNDI for my web application inside the applicaton's
WAR file itself to no avail.  If I use the same configuration, but put it in
my server's context.xml, it works fine.

Here is the configuration I am using:
[code]
<?xml version="1.0" encoding="US-ASCII"?>
	<!--
		http://tomcat.apache.org/tomcat-6.0-doc/config/context.html Even
		though this works inside of tomcat/conf/context.xml and the
		documentation says it should work here, it doesn't
	-->
<context reloadable="true">
	<WatchedResource>WEB-INF/web.xml</WatchedResource>
	<WatchedResource>META-INF/context.xml</WatchedResource>
	<Resource name="${jndi.URL}" auth="Container" type="javax.sql.DataSource"
		driverClassName="${jdbc.driverClassName}" url="${jdbc.url}"
username="${jdbc.username}"
		password="${jdbc.password}" maxActive="100" maxIdle="30" maxWait="10000"
/>
</context>
[/code]

The parameters specified dynamically via ${} are filtered via
maven-resources-plugin, so that is not an issue.  The issue is just with
this configuration placed inside my webapp, I can't get a JNDI connection,
but if it is in the server's context.xml, it works great.

Walter

Hi,

Thanks for your reply, but I am still getting the same error.

[code]

		useNaming="true"/>
</context>
[/code]

I tried putting useNaming in the resource element as well as the context
element, but all to no avail.  It looks like this configuration is not doing
anything.  This file is supposed to be placed in
servlet.war/META-INF/context.xml in which the servlet.war is the actual
file.  Could it also go in /WEB-INF/classes/META-INF/context.xml?

I tried both places, but nothing changed.

Please let me know what else to try.

Thanks,
Walter

Also, exactly where is the above <Context> element located?

If you have a <Context> element in conf/Catalina/[host]/[appName].xml that might have been created from a previous deployment, that will override the one in META-INF/context.xml.  Get rid of the [appName].xml one if it exists.

Could the double-XML processing instruction be causing a choke?

Hi,

Here are the exact contents in the file after maven filters it.

[code]
<?xml version='1.0' encoding='utf-8'?>
<!--
	http://tomcat.apache.org/tomcat-6.0-doc/config/context.html Even
	though this works inside of tomcat/conf/context.xml and the
	documentation says it should work here, it doesn't

	though this works inside of tomcat/conf/context.xml and the
	documentation says it should work here, it doesn't
-->
<Context>
	<WatchedResource>WEB-INF/web.xml</WatchedResource>
	<!--<WatchedResource>META-INF/context.xml</WatchedResource>-->
	<Resource name="jdbc/serverConsole" auth="Container"
type="javax.sql.DataSource"
		driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/serverConsole?createDatabaseIfNotExist=true&amp;useUnicode=true&amp;characterEncoding=utf-8&amp;useCompression=true&amp;zeroDateTimeBehavior=convertToNull"
username="serverConsole"
		password="serverConsole" maxActive="100" maxIdle="30" maxWait="10000"/>
</Context>
[/code]

Let me know if that helps. I have redeployed the web app a few times with
this configuration to no avail.  It must be something small - Is there
anything in Tomcat that may enable/disable this configuration in the web
application itself?

Without seeing what's really being inserted for the various attributes, I don't think it's possible to go much further as is.  For now, try replacing the variable references with the actual values and see what happens.

Hi,

Thanks for your reply.  I noticed my configuration in the Tomcat
installation directory did have a capital C in context.  However, the files
are identical now, but I'm still not getting a JNDI connection.

[code]
<?xml version='1.0' encoding='utf-8'?>
<!--
	http://tomcat.apache.org/tomcat-6.0-doc/config/context.html Even
	though this works inside of tomcat/conf/context.xml and the

<Context>
	<WatchedResource>WEB-INF/web.xml</WatchedResource>
	<!--<WatchedResource>META-INF/context.xml</WatchedResource>-->
	<Resource name="${jndi.URL}" auth="Container" type="javax.sql.DataSource"
		driverClassName="${jdbc.driver}" url="${jdbc.url}"
username="${jdbc.username}"
		password="${jdbc.password}" maxActive="100" maxIdle="30" maxWait="10000"/>
</Context>
[/code]

Thanks for your suggestion, please let me know what else to try.

I am running Tomcat 6.0.18 on Linux.

Thanks,
Walter
