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

<h3 id="java.io.IOExceptionFailedtocreatedatabase'derbydb',seethenextexceptionfordetails-Workaround">Workaround</h3>

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

<div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
File dir = new File("foo");
dir.mkdir();
broker.setDataDirectory(dir);
</pre>
</div></div>

<p>or in XML use</p>

<div class="code panel pdl" style="border-width: 1px;"><div class="codeContent panelContent pdl">
<pre class="brush: java; gutter: false; theme: Default" style="font-size:12px;">
&lt;broker dataDirectory="foo"&gt;...
