Crear un datasource en tiempo de ejecucion en Struts

[ndaniel8a]

Uso apache tomcat 5.0 he mirado algun codigo como el siguiente:

ModuleConfig config = (ModuleConfig)request.getAttribute("org.apache.str uts.action.MODULE");
if(config == null) {
config = (ModuleConfig) getServlet().getServletContext().getAttribute("org .apache.struts.action.MODULE");
}

DataSourceConfig newdsc = config.findDataSourceConfig("conexion1");

newdsc.addProperty("URL", "jdbc:oracle:thin:@localhost:1521:unionsol");
newdsc.addProperty("user", "xxxx");
newdsc.addProperty("password", "xxx");
newdsc.addProperty("maxActive", "3");
newdsc.addProperty("maxWait", "5000");
newdsc.addProperty("defaultAutoCommit", "false");


pero siempre me sale un error en el tomcat al momento de hacer eso algo con frozen...como si me digera que la configuracion esta detenida y que no puedo modificarla..lo mismo pasa si trato de crear uno nuevo... Por eso pienso que a lo mejor no se puede crear en tiempo de ejecucion o me falta algo para poder hacerlo..tal vez reiniciar el server..por codigo..pero eso como se hace???

El error que me saca es:
