title: Append to the end of derby.database.classpath
body: <p>In Apache Derby, it's possible to add multiple entries to derby.database.classpath using by using a colon separator. Like this:</p>
  
  <pre><code>call SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.classpath', 'APP.StringUtilities:APP.FileUtilities');
  </code></pre>
  
  <p>That works well if you know in advance what things need to be loaded. In my case, a database is shared between a number of applications, each of which can install jar files into it.</p>
  
  <p>I'd like to know if it's possible to append to an existing list, much like in linux you might do a:</p>
  
  <pre><code>export CLASSPATH=${CLASSPATH}:SomeOtherFile.jar
  </code></pre>
  
  <p>I've tried this:</p>
  
  <pre><code>call SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.classpath', select SYSCS_UTIL.SYSCS_GET_DATABASE_PROPERTY('derby.database.classpath') || ':APP.FileUtilities' from SYSIBM.SYSDUMMY1);
  </code></pre>
  
  <p>And this:</p>
  
  <pre><code>call SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.database.classpath', values SYSCS_UTIL.SYSCS_GET_DATABASE_PROPERTY('derby.database.classpath') || ':APP.FileUtilities');
  </code></pre>
  
  <p>But neither worked. Is there any way to append to the existing value of derby.database.classpath?</p>
