J2C Connection Factories settings

Use this page to specify settings for a connection factory.

To view this administrative console page, click Resources > Resource Adapters > resource_adapter > J2C connection factories >J2C_connection_factory.

Configuration tab

Scope

Specifies the scope of the resource adapter that connects applications to an enterprise information system (EIS) through this connection factory. Only applications that are installed within this scope can use this connection factory.

Name

Specifies a list of connection factory display names.

This is a required property.

Data type String
JNDI Name

Specifies the JNDI name of this connection factory.

For example, the name could be eis/myECIConnection.

After you set this value, save it and restart the server. You can see this string when you run the dumpNameSpace tool. This is a required property. If you do not specify a JNDI name, it is filled in by default using the Name field.

Data type String
Default eis/display name
Important: Adhere to the following requirements for JNDI names:
  • Do not assign duplicate JNDI names across different resource types (such as data sources versus J2C connection factories or JMS connection factories).
  • Do not assign duplicate JNDI names for multiple resources of the same type in the same scope.
Description

Specifies a text description of this connection factory.

Data type String
Connection Factory Interface

Specifies the fully qualified name of the Connection Factory Interfaces supported by the resource adapter.

This is a required property. For new objects, the list of available classes is provided by the resource adapter in a drop-down list. After you create the connection factory, the field is a read only text field.

Data type Drop-down list or text
Category

Specifies a string that you can use to classify or group this connection factory.

Data type String
Component-managed Authentication Alias

Specifies authentication data for component-managed signon to the resource.

Choose from aliases defined under Security >JAAS Configuration > J2C Authentication Data.

To define a new alias not already appearing in the pick list:
  • Click Apply to expose Related Items.
  • Click J2C Authentication Data Entries.
  • Define an alias.
  • Click the connection factory name at the top of the J2C Authentication Data Entries page to return to the connection factory page.
  • Select the alias.
Data type List
Note: The alias that you configure for component-managed authentication does not apply to all clients that must access the secured resource. External Java clients with Java Naming and Directory Interface (JNDI) access can look up a Java 2 Connector (J2C) resource such as a data source or Java Message Service (JMS) queue. However, they are not permitted to take advantage of the component-managed authentication alias defined on the resource. This alias is a default value used when the user and password are not supplied on the getConnection() call. Therefore, if an external client needs to get a connection, it must assume responsibility for the authentication by passing it through arguments on the getConnection() call.

However, if clients such as servlets or enterprise beans run in WebSphere Application Server processes within the same cell, and can look up a resources in the JNDI namespace, these clients can obtain connections without explicitly providing authentication data on the getConnection() call. In this case, if the component’s res-auth setting is Application, authentication is taken from the component-managed authentication alias defined on the connection factory. With res-auth set to Container, authentication is taken from the login configuration defined on the component’s resource-reference. It is important to note that J2C authentication alias is per cell. An enterprise bean or servlet in one application server cannot look up a resource in another server process which is in a different cell, because the alias would not be resolved.

Authentication Alias for XA Recovery

This optional field is used to specify the authentication alias that should be used during XA recovery processing.

If the resource adapter does not support XA transactions, then this field will not be displayed. The default value will come from the selected alias for application authentication (if specified).

Use Component-managed Authentication Alias
Selecting this radio button specifies that the alias set for component-managed authentication is used at XA recovery time.
Data type Radio button
Specify:
Selecting this radio button enables you to choose an authentication alias from a drop-down list of configured aliases.
Data type Radio button
Container-managed Authentication Alias (deprecated)

Specifies authentication data (a string path converted to userid and password) for container-managed signon to the resource.

Note: Beginning with WebSphere Application Server Version 6.0, the container-managed authentication alias is superseded by the specification of a login configuration on the resource-reference mapping at deployment time, for components with res-auth=Container.

Choose from aliases defined under Security>JAAS Configuration> J2C Authentication Data.

To define a new alias not already appearing in the pick list:
  • Click Apply to expose Related Items.
  • Click J2C Authentication Data Entries.
  • Define an alias.
  • Click the connection factory name at the top of the J2C Authentication Data Entries page to return to the connection factory page.
  • Select the alias.
Data type Pick-list
Authentication Preference (deprecated)

Specifies the authentication mechanisms defined for this connection factory.

Note: Beginning with WebSphere Application Server Version 6.0, the authentication preference is superseded by the combination of the <res-auth> application component deployment descriptor setting and the specification of a login configuration on the resource-reference mapping at deployment time.

This setting specifies which of the authentication mechanisms defined for the corresponding resource adapter applies to this connection factory. Common values, depending on the capabilities of the resource adapter, are: KERBEROS, BASIC_PASSWORD, and None.

If None is chosen, the application component is expected to manage authentication (<res-auth>Application</res-auth>). In this case, the user ID and password are taken from one of the following:
  • The component-managed authentication alias
  • UserName, Password Custom Properties
  • Strings passed on the getConnection method
For example, if two authentication mechanism entries are defined for a resource adapter in the ra.xml document:
  • <authentication-mechanism-type>BasicPassword</authentication-mechanism-type>
  • <authentication-mechanism-type>Kerbv5</authentication-mechanism-type>
the authentication preference specifies the mechanism to use for container-managed authentication. An exception is issued during server startup if a mechanism that is not supported by the resource adapter is selected.
Data type Pick-list
Default BASIC_PASSWORD
Mapping-Configuration Alias (deprecated)

Specifies the authentication alias for the Java Authentication and Authorization Service (JAAS) mapping configuration that is used by this connection factory.

Note: Beginning with WebSphere Application Server Version 6.0, the Mapping-Configuration Alias is superseded by the specification of a login configuration on the resource-reference mapping at deployment time, for components with res-auth=Container.

Click Security > JAAS Configuration > Application Logins Configuration and select an alias from the list.

The DefaultPrincipalMapping JAAS configuration maps the authentication alias to the userid and password. You may define and use other mapping configurations.
