Description

This tag creates an installation of the implementing class. This typically involves creating the catalogs to allow for storage of instances of the class. The installation method should use one of the following prototypes:

• public static int Install (ICS ics, Vector vector, String sUpLoadDir, String sAcList, boolean bTrack)

• public static int Install (ICS ics, Vector vector, String sUpLoadDir, String sAcList, boolean bTrack, String sArg1)

• public static int Install (ICS ics, Vector vector, String sUpLoadDir, String sAcList, boolean bTrack, String sArg1, String Arg2)

The argument in the second prototype is a vector of a column elements, represented by the ColumnElement class. These typically represent column definitions using the ColumnDefinition class.

Error Numbers

The possible values of errno include:

Value	Description
-10001	Implementing class is invalid.
-10002	There is a missing method for the implementing class.
-10003	The method could not be invoked successfully.
-10004	A required parameter is missing
-10010	Invalid attribute value.

Example

The following example creates an object table with the additional columns name and description.

<object:install classname="com.openmarket.framework.objects.AbstractObject"
arg1 ="sample">
      <object:argument name="name" value="varchar(32)NOT NULL"/>
      <object:argument name="description" value="varchar (128)NOT NULL"/>
</object:install>
