Error compiling JNLP projects under stock NetBeans 6.x

Hello,
I am facing a terrible problem with NetBeans when I try for an update. However, it fails every time, leaving a message ‘Reference problems one or more projects resources could not be found’. More information JSF projects with NetBeans using TortoiseSVN (Subversion). How to find the jars? How to fix the Resolve conflicts in the project? Please help me.

Open Project
Reference Problems
One or more project resources could not be found.
Right-click the project in the Projects window and choose
Resolve Reference Problems to find the missing resources.
