ECMAScript Methods

The J2EE Connector framework of the exteNd Composer Connect for J.D. Edwards OneWorld implements a number of ECMAScript extension methods that are available for use through the Expression Builder (which is available in Function Actions and elsewhere). You will find the methods listed in the Functions/Methods pane of the Expression Builder:

ECMA

ToolTip help is available for each method.

For more information about working with the Expression Builder, see "Custom Scripting and XPath Logic in exteNd Composer" in the Novell exteNd Composer User's Guide.

Adapter Interface Methods

getAdapterType

This method calls the IGNVAdapterInterface.getAdapterType(), and returns the adapter type name (e.g., "jde").

Syntax: getAdapterType()

Connection Interface Methods

The following CCI API metadata-wrapped methods are published through the Expression Builder.

getAdapterMetaData

This method wraps calls on the javax.resource.cci.ResourceAdapterMetaData class.

Syntax:getAdapterMetaData(parameter)

Table 1: Parameters for getAdapterMetaData
Parameter	Description
NAME	Returns the name of the adapter (e.g., "iWay JCA adapter").
EXECUTEWITHI	Returns true if the implementation class for the Interaction interface implements public Record execute method; otherwise the method returns false.
EXECUTEWITHIO	Returns true if the implementation class for the Interaction interface implements public boolean execute method; otherwise the method returns false.
VENDOR	Returns the name of the vendor that has provided the resource adapter (e.g., "iWay Software, Inc.").
VERSION	Returns the version of the resource adapter (e.g., "5.5").
INTERACTIONSPECS	Returns the fully-qualified name of the InteractionSpec type supported by this resource adapter (e.g., "com.ibi.afjca.IWAFInteractionSpec").
SPECVERSION	Returns a string representation of the version of the connector architecture specification that is supported by the resource adapter (e.g., "1.0").
LOCALTX	Returns true if the resource adapter implements the LocalTransaction interface and supports local transaction demarcation on the underlying EIS (Enterprise Information System) instance through the LocalTransaction interface.

getConnectionMetaData

This method wraps calls on the javax.resource.cci.ConnectionMetaData class.

Syntax:getConnectionMetaData(parameter)

Table 2: Parameters for getConnectionMetaData
Parameter	Description
EISPRODUCTNAME	Returns the product name of the underlying EIS instance (e.g., "JDEdwards").
EISPRODUCTVERSION	Returns product version of the underlying EIS instance (e.g., "OneWorld").
USER	Returns the user name for an active connection as known to the underlying EIS instance.

Additional Methods

The following ECMA-wrapped methods are not displayed by the Expression Builder user interface, but you can use them in the Expression Builder by typing them directly into expressions.

getWarnings()

Returns line separated list of javax.resource.cci.ResourceWarning for the javax.resource.cci.Interaction.

clearWarnings()

Calls javax.resource.cci.Interaction.clearWarnings().

getLastError()

Returns last error, such as a javax.resource.ResourceException.
