Thanks Rajarshi
Upgrading to 3.0.5 solved the problem. FYI I was using rcdklibs 1.3.5.3.

Subject: Re: [Cdk-user] jcall error in rcdk
Works fine on 2.12.2 on 64 bit Centos.
Try installing 3.0.5 from the source package available on CRAN. Are you also
using rcdklibs 1.3.6.3

Hi
I have recently upgraded to R 2.12.2 with rcdk v 3.0.1 on Mac OS X (Snow
Leopard) and I'm trying to get a list of descriptor names, but I'm getting some
odd behaviour:
dn <- get.desc.names()
-- expected result
dc <- get.desc.categories()
-- expected result
dn <- get.desc.names(dc[1])
Error in .jcall("org/guha/rcdk/descriptors/DescriptorUtilities",
"[Ljava/lang/String;", :
java.lang.NullPointerException
dn <- get.desc.names("electronic")
Error in .jcall("org/guha/rcdk/descriptors/DescriptorUtilities",
"[Ljava/lang/String;", :
java.lang.NullPointerException
Has anyone else seen this behaviour, or know what might be causing it? I'm
afraid I'm not a Java programmer, so it's all a bit of a mystery to me!
Thanks for your help.
