The GlobalNamingResources element defines the global
JNDI resources for the Server.
These resources are listed in the server's global JNDI resource context.
This context is distinct from the per-web-application JNDI contexts
described in
the JNDI Resources HOW-TO.
The resources defined in this element are not visible in
the per-web-application contexts unless you explicitly link them with
<ResourceLink> elements.

Special Features |
Environment Entries |
You can configure named values that will be made visible to all
web applications as environment entry resources by nesting
<Environment> entries inside this element. For
example, you can create an environment entry like this:
| | | |
<GlobalNamingResources ...>
...
<Environment name="maxExemptions" value="10"
type="java.lang.Integer" override="false"/>
...
</GlobalNamingResources>
| | | | |
This is equivalent to the inclusion of the following element in the
web application deployment descriptor (/WEB-INF/web.xml ):
| | | |
<env-entry>
<env-entry-name>maxExemptions</env-entry-name>
<env-entry-value>10</env-entry-value>
<env-entry-type>java.lang.Integer</env-entry-type>
</env-entry>
| | | | |
but does not require modification of the deployment descriptor
to customize this value.
The valid attributes for an <Environment> element
are as follows:
Attribute | Description |
---|
description |
Optional, human-readable description of this environment entry.
| name |
The name of the environment entry to be created, relative to the
java:comp/env context.
| override |
Set this to false if you do not want
an <env-entry> for the same environment entry name,
found in the web application deployment descriptor, to override the
value specified here. By default, overrides are allowed.
| type |
The fully qualified Java class name expected by the web application
for this environment entry. Must be one of the legal values for
<env-entry-type> in the web application deployment
descriptor: java.lang.Boolean ,
java.lang.Byte , java.lang.Character ,
java.lang.Double , java.lang.Float ,
java.lang.Integer , java.lang.Long ,
java.lang.Short , or java.lang.String .
| value |
The parameter value that will be presented to the application
when requested from the JNDI context. This value must be convertable
to the Java type defined by the type attribute.
|
|
Transaction |
You can declare the characteristics of the UserTransaction
to be returned for JNDI lookup for java:comp/UserTransaction .
You MUST define an object factory class to instantiate
this object as well as the needed resource parameters as attributes of the
Transaction
element, and the properties used to configure that object factory.
The valid attributes for the <Transaction> element
are as follows:
Attribute | Description |
---|
factory |
The class name for the JNDI object factory.
