Hi All,
I'm trying to compile an XML schema using JAXB 2.1.10 against JamVM:
jamvm -verbose -Djava.endorsed.dirs=/usr/local/jamvm/jre/lib/endorsed -jar
jaxb-xjc.jar messages.xsd
But I'm getting java.lang.NullPointerException. Below is a snippet from a
verbose debug stack trace:
.

It looks like the Gnu class (gnu.xml.validation.xmlschema.XMLSchemaBuilder)
is incompatible with JAXB's
class (org.relaxng.datatype.helpers.DatatypeLibraryLoader).
Is this an incompatibility issue?
Is JamVM/Classpath compatible with Sun's JAXB?
Any help would be greatly appreciated.
Regards,
Teresa

Hi Teresa, On Sun, 2009-03-01 at 00:24 -0800, Teresa L.

This looks like the following GNU Classpath bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38149 There is a suggestion in comment #1 on how to solve it. Could you try that out? If it works, we need to patch it upstream. Thanks, Mark |

Hi Mark,
Thanks for your reply. I made the suggested changes in the getResources()
method of Loader2
so that it reflects the following:
Enumeration getResources(String resName) {
ClassLoader cl = Loader.class.getClassLoader();
URL url;
if (cl == null)
url = ClassLoader.getSystemResource(resName);
else
url = cl.getResource(resName);
return new Singleton(url);
}
It did work and I no longer received a NullPointerException in
DatatypeLibraryLoader.
However, a new error occurs:
java.lang.annotation.AnnotationTypeMismatchException
when executing the following line:
jamvm -verbose -Djava.endorsed.dirs=/usr/local/jamvm/jre/lib/endorsed
-Djavax.xml.datatype.DatatypeFactory=com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl
-jar jaxb-xjc.jar message.xsd
javax.xml.datatype.DatatypeFactory points to JAXP's implementation since
gnu.xml.datatype.JAXPDatatypeFactory doesn't exist.

The error stems from the following code in AnnotationInvocationHandler.java
(line:379):
public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable
{
String methodName = method.getName().intern();
if (args == null || args.length == 0)
{
if (methodName == "toString")
{
return toString(type, memberValues);
}
else if (methodName == "hashCode")
{
return Integer.valueOf(hashCode(type, memberValues));
}
else if (methodName == "annotationType")
{
return type;
}
else
{
Object val = memberValues.get(methodName);
if (val == null)
{
throw new IncompleteAnnotationException(type,
methodName);
}
if (! getBoxedReturnType(method).isInstance(val))
{
throw new AnnotationTypeMismatchException(method,
val.getClass().getName());
}
<------------------------------------------------------------------------------------------------------
line 379
if (val.getClass().isArray())
{
val = arrayClone(val);
}
return val;
}
}
else if (args.length == 1)
{
if (methodName == "equals")
{
return Boolean.valueOf(equals(type, memberValues, args[0]));
}
}
throw new InternalError("Invalid annotation proxy");
}
It appears that "val" is an instance of an unexpected type.
Do you know if there's a workaround for this error? Or is this a case of
incompatibility?
Again, many, many thanks for your help.
Regards,
Teresa

Hi Chris,
Ah.
That might explain the java.lang.annotation.AnnotationTypeMismatchException
that I'm having.
Thanks!
