<p> Connection to an LTPDA Repository is normally carried out as part of other processes. For example, when submitting an object to the repository using the <tt>submit</tt> command, the user is prompted to login to the chosen repository.</p><p> It is also possible to connect to a repository using a script interface. The result is a connection object which can be passed to other methods (for example, <tt>submit</tt>), thus allowing the construction of more automated procedures for interacting with repositories.</p><p> To connect to a repository using the script interface, us the command <tt>utils.jmysql.connect</tt>. It takes the following input arguments: <table border="1" cellpadding="2" width="30%" bgcolor="#DDDDDD"> <tr valign="top"> <td><tt>hostname</tt></td><td>A hostname for the repository</td> </tr> <tr valign="top"> <td><tt>dbname</tt></td><td>A database name to connect to</td> </tr> <tr valign="top"> <td><tt>username</tt></td><td>[optional] A username to connect with</td> </tr> <tr valign="top"> <td><tt>username</tt></td><td>[optional] A password to connect with</td> </tr> </table> <br> If you don't supply them as input arguments, you will then be prompted for a valid username and password.<br>The result is a <tt>mpipeline.repository.RepositoryConnection</tt> object which can be further used to interact with the repository.<br>To disconnect from the server, use the <tt>closeConnection</tt> method of the <tt>mpipeline.repository.RepositoryConnection</tt> class:<div class="fragment"><pre> >> conn.closeConnection</pre></div> </p>
