Help with JNDI Catalina 4 (May 30 build)

[Arshad Mahmood <ar...@compuvision.co.uk>]

Hi,

I am trying to use JNDI to access some resources.I wonder if someone knows how to use the GlobalNamingResources.

Here is a snippet from my server.xml

  <GlobalNamingResources>

    <!-- the file based cache for all web applications -->
    <Resource name="rohas/filecache" auth="Container" type="com.rohas.cache.FileCache" />
    <ResourceParams name="rohas/filecache">
        <parameter>
            <name>factory</name>
            <value>com.rohas.cache.FileCacheFactory</value>
        </parameter>
        <parameter>
            <name>cacheDir</name>
            <value>/tmp/cache</value>
        </parameter>
    </ResourceParams>

    .....

I have then defined a link to this in my context as follows :-

<Context path="" docBase="www.compuvision.co.uk" debug="0" reloadable="true"
                 crossContext="false" cookies="true" >
        <ResourceLink name="rohas/filecache" global="rohas/filecache"
                type="com.rohas.cache.FileCache" />
    ....

The code to load the resource is defined as follows ::-

            /* Get the file cache from the context via JNDI */
            initCtx = new InitialContext();
            envCtx = (Context)initCtx.lookup("java:comp/env");

            /* retrieve the file cache */
            fileCache = (FileCache)envCtx.lookup("rohas/filecache");

The resource is loaded as part of the startup for my servlet. When I start catalina I get the following error:-

javax.naming.NameNotFoundException: Name rohas is not bound in this Context
        at org.apache.naming.NamingContext.lookup(Unknown Source)
        at org.apache.naming.NamingContext.lookup(Unknown Source)
        at com.rohas.util.MasterServlet.init(MasterServlet.java:76)
        at javax.servlet.GenericServlet.init(GenericServlet.java:258)
        at org.apache.catalina.core.StandardWrapper.loadServlet(Unknown Source)
        at org.apache.catalina.core.StandardWrapper.load(Unknown Source)
        at org.apache.catalina.core.StandardContext.loadOnStartup(Unknown Source)
        at org.apache.catalina.core.StandardContext.start(Unknown Source)

One answer could be to define the resources in each context, but this is a pain as I am probably going to have about 6/7 contexts each of which use this shared resource.

Can anybody help ? Am I using the global resources in completely the wrong way ???
