title: Domino 9 FP10 xpages external JAR
body: <p>While doing a Test upgrade from Domino 9 FP8 to Domino 9 FP10 HF197 on an application that uses an external JAR "com.google.gson" ran into an error of java.lang.NoClassDefFoundError:. The application works fine on the FP8 installation with the JAR in the NSF file.  But on the FP10 installation I had to copy the JAR in the jvm/lib/ext folder for the application to work. I read several posts and play around with the Build, Manifest and other settings but nothing made any different.  Can someone explain what I'm missing with the eclipse setup or does external JAR now need to go into the jvm/lib/ext folder ?  We also upgrading the Domino 10 are there any issues that I need to look out for like this ? 
  Thank you
