[Pattabhi RK]

Hi,

  We are trying to develop a libreoffice extension for spellchecker. And to
start with we have tried to develop HelloWorld extension as given in the
link.

error:


om.sun.star.registry.InvalidRegistryException:
com.sun.star.registry.SimpleRegistry.open(file:///opt/libreoffice5.4/program/types.rdb):

When we have loaded the LibreOffice and SDK using "Window > Preference >
LibreOffice Path, we got message saying " Office bootstrapped"

So we are not able to understand where we are going wrong. I request you to
kindly help in resolving this problem.


We are using Eclipse Oxygen 2, Libreoffice 5.4.5 and sdk 5.4.5. And using
Ubuntu 14.04 LTS.

Thanks,
