EclipseLink DBWSBuilder File

The DBWSBuilder design-time utility processes the elements in this file to produce the requisite EclipseLink DBWS service descriptor and accompanying files. The XML Schema definition for a DBWSBuilder file is eclipselink-dbws-builder_1.0.xsd and can be found in the META-INF/ directory in the eclipselink-dbwsutils.jar file, located in the <ECLIPSELINK_HOME>/utils/dbws/ directory. The file has two main sections - global properties settings and specific operation settings.

    ...
    <url-pattern>
        /servlet/MyWebService
    </url-pattern>
</servlet-mapping>

No

" / "+ projectName

dataSource

JNDI datasource location for the EclipseLink sessions.xml file You must configure a JNDI datasource before deploying your EclipseLink DBWS to a Java-EE server

No

None

sessionsFileName

The name of EclipseLink sessions.xml file to add to the EclipseLink DBWS service archive file.

No

eclipselink-dbws-sessions.xml

platformClassname

The fully qualified name of the EclipseLink database platform class to use to connect to the relational database. This class must be in the classpath.

No

org.eclipse.persistence.platform.database.MySQLPlatform

orSessionCustomizerClassName

logLevel

EclipseLink logging level to be inserted in the EclipseLink database Web service sessions.xml file. Controls the amount and detail of log output by configuring the log level (in ascending order of information) to one of the following java.util.logging.Level values:

  • off - Disable logging.
  • severe - Logs exceptions indicating EclipseLink cannot continue, as well as any exceptions generated during login. This includes a stack trace.
  • warning - Logs exceptions that do not force EclipseLink to stop, including all exceptions not logged with severe level. This does not include a stack trace.
  • info - Logs the login/logout per sever session, including the user name. After acquiring the session, detailed information is logged.
  • config - Logs only login, JDBC connection, and database information.
  • fine - Logs SQL.
  • finer - Similar to warning. Includes stack trace.
  • finest - Includes additional low level information.

No

info

targetNameSpace

The URI of the target namespace that the EclipseLink Database Web service inserts into the eclipselink-dbws-schema.xsd file.

The following tables describe attributes of builder operations.
This table lists attributes common to all three builder operations - table, procedure and sql.

Common Attributes of Builder Operations
Attribute Description Default

name

Name of the operation.

None

isCollection

Specifies whether or not the procedure returns multiple results. The following are valid values:
  • true - the operation returns more than a single row.
  • false - the operation returns a single row.

false

isSimpleXMLFormat

Specifies whether or not the procedure returns information in the Simple XML Format (SXF). The following are valid values:

  • true - the operation returns information in the Simple XML Format.
  • false - the operation returns information in the Simple XML Format.

For more information, see foobar

false

simpleXMLFormatTag

The name of the root-level Simple XML Format element-tag. For more information, see foobar

<simple-xml-format>

xmlTag

The name of the grouping XML element-tag for rows. For more information, see foobar

<simple-xml>

binaryAttachment

Specifies whether or not the operation returns binary data as a SOAP attachment. The following are valid values:

  • true - the operation returns binary data as a SOAP attachment.
  • false - the operation does not return binary data as a SOAP attachment.

false

returnType

Specifies a return type when the operation's return type cannot be deduced from database metadata. Valid values are any type that the eclipselink-dbws-schema.xsd file defines.

Note: This attribute is optional.

None


This table lists attributes of the procedure operation.

procedurePattern

A pattern that matches one or more stored procedure, stored function, or stored trigger names in the database identified by the parent operation (supports SQL-92 % wild-card).

This table lists attributes of the table operation.

Attributes of the table Operation
Attribute Description
