Problem of Developer's Guide Examples "OOoBeanViewer"

I want to see if i can embed Libreoffice in a Java Application. And i tried with the “Developer’s Guide Examples” on link
http://api.libreoffice.org/examples/DevelopersGuide/OfficeBean/OOoBeanVi....

After i installing Libreoffice & SDK with version 4.2.5 and finish the code(uploaded libre_OOoBeanViewer.zip), the demo UI can show normally, but if i click “new document” and select any item, Exception throws as.

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no officebean in java.library.path

For this Exception, i guess it might cause “libofficebean.so” file which in “/opt/libreoffice/program” was not involved in current property “java.library.path”. I tried with the folloing code to update system property.

 String property = System.getProperty("java.library.path");
 System.setProperty("java.library.path", property + ":/opt/libreoffice4.2/program");
 System.out.println("java.library.path=" + System.getProperty("java.library.path"));

But it’s no use. Please refer the attached “6.jpg”.

And if you try “new document”, another Exception throws as follow

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: Could not initialize class com.sun.star.comp.beans.LocalOfficeConnection
	at com.sun.star.comp.beans.OOoBean.getOOoConnection(OOoBean.java:269)

	at com.test.oobean.OOoBeanViewer$5.actionPerformed(OOoBeanViewer.java:168)
	at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018)

Does anybody can help me solve this problem? Any suggestion & help is greatly appreciated.

Thanks
