Problem trying to run JAXB samples in JWSDP

[Mark Thomas]

I've been trying to run the sample apps supplied by Sun as part of the
JWSDP. The ant script supplied fails & I can't work out what's going
wrong. Here's what I get:

C:\Sun\jwsdp-2.0\jaxb\samples\unmarshal-read>ant
Buildfile: build.xml

compile:
[echo] Compiling the schema...
[xjc]
C:\Sun\jwsdp-2.0\jaxb\samples\unmarshal-read\gen-src\primer.po is no
t found and thus excluded from the dependency check

BUILD FAILED
java.lang.NullPointerException

Total time: 0 seconds

Any ideas?
