## weblogic.apache.xalan.lib.sql
Class DefaultConnectionPool

    java.lang.Object
      |
      +--weblogic.apache.xalan.lib.sql.DefaultConnectionPool

public class DefaultConnectionPool
extends java.lang.Object
implements ConnectionPool

For internal connectiones, i.e. Connection information supplies in the Stylesheet. The Default Connection Pool will be used.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.
