<p>Then the error is probably that the JDBC driver (Apache Derby by default) could not write to the persistent file area.</p>

<h3>Workaround</h3>

<p>Create a directory for the broker to write its files. e.g. in Java code call <a shape="rect" href="http://incubator.apache.org/activemq/maven/activemq-core/apidocs/org/apache/activemq/broker/BrokerService.html#setDataDirectory(java.io.File)">setDataDirectory</a></p>

<structured-macro ac:macro-id="ec2ce45d-ff66-4b44-86af-55df31e71c78" ac:name="code" ac:schema-version="1"><plain-text-body>
File dir = new File("foo");
dir.mkdir();
broker.setDataDirectory(dir);
</plain-text-body></structured-macro>

<p>or in XML use</p>

&lt;broker dataDirectory="foo"&gt;...
