jaxb - getting InvocationTargetException during parsing

[Wei Hsu]

Hi all,
I'm trying to get JAXB to generate the java classes by using xjc.sh on test.xsd (shown below). Apparently, JAXB does not like it when i try to use extension on a complexType/simpleContent/Restriction? Is there something i'm doing wrong or does xjc.sh not support what i'm trying to do? Would appreciate any help/hints. Thanks!
I am using jwsdp-1.3 and j2sdk1.4.1_02.
I've tried the following command line invocations:
xjc.sh -p <package name> -d <working dir> test.xsd
xjc.sh -p <package name> test.xsd
xjc.sh test.xsd

----- test.xsd -----
