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

Workaround

Create a directory for the broker to write its files. e.g. in Java code call setDataDirectory

File dir = new File("foo");
dir.mkdir();
broker.setDataDirectory(dir);

or in XML use

<broker dataDirectory="foo">...
