Hola amigos de java hispano.
sucede que estoy tratando de usar un jsdatepicker (calendiario de la libreria xSwing), pero ademas uso para mi aplicacion las librerias look and feel. sucede que al arrancar la aplicacion le lanza el siguiente error:

UIDefaults.getUI() failed: no ComponentUI class for: org.jdesktop.swingx.JXMonthView[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,border=,flags=0,maximumSize=,minimumSize=,preferredSize=]

GENERACIÓN CORRECTA (total time: 3 seconds)

por favor si alguien sabe la solucion para eso les agradeceria que me pasen el dato

import de.javasoft.plaf.synthetica.SyntheticaBlueMoonLookAndFeel;

y cuando arranca el jframe hace esto y trae la forma visual
try {
UIManager.setLookAndFeel(new SyntheticaBlueMoonLookAndFeel());
} catch (Exception e) {
JOptionPane.showMessageDialog(null, "ERROR" + e.getMessage());
}

necesito usar ese estilo de look and feel, no habra otra solucion??
