<DT><B>Throws:</B>
<DD><CODE>java.io.IOException</CODE> - If something goes wrong in loading properties file.</DL>

<PRE>
public <A HREF="../../javatools/db/DbDatabase.html">DbDatabase</A> <B>getDatabase</B>(java.lang.String&nbsp;name,
                              java.lang.String&nbsp;driver,

                       throws <A HREF="../../javatools/db/DbException.html">DbException</A></PRE>
<DL>
<DD>Return the database object associated with this name or parameters. If you
 don't give a name DbManager won't be able to cache DbDatabase objects, so
 giving a name is recommended. Usually the name will be just something which
 identifies this application. Once a DbDatabase is in the cache you can use
 the getDatabase(name) with one argument. Alternatively you can always use
 the one argument version and the parameters will come from the
 db.properties file.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - An arbitrary name used to identify this DbDatabase.<DD><CODE>driver</CODE> - The Java JDBC driver class name.<DD><CODE>connectString</CODE> - The JDBC connect string.<DD><CODE>userName</CODE> - The database connect user name.<DD><CODE>password</CODE> - The database connect password.
<DT><B>Returns:</B><DD>The database value

<A NAME="getDatabase(java.lang.String)"><!-- --></A><H3>

<PRE>

                       throws <A HREF="../../javatools/db/DbException.html">DbException</A></PRE>
<DL>
<DD>Return the database associated with this name. If the database is already
 in the cache we return that, otherwise we attempt to read a db properties
 file and get a connect configuration from that with <name>.<property>

 . For example, you could have a notional database called "foo". Then in
 your db.properties file you might have a setup like: <PRE>
 foo.driver  = oracle.jdbc.driver.OracleDriver
 foo.connect = jdbc:oracle:thin:@dbdev01:1521:devu02
 foo.userId = foouserid
 foo.password = foopassword
 </PRE> In terms of where the db.properties file will be located, that is
 determined by the javatools.util.Props class.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - The name in the cache and/or in the db.properties
     file.
