------------------------------------
Summary: Jaxb Integration with EclipseLink has Error
Key: CXF-8836
URL: https://issues.apache.org/jira/browse/CXF-8836
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 4.0.0
Reporter: Andreas Rusjaev
Dear CXF developers,
I am using version 4.0.0 of CXF cxf-spring-boot-starter-jaxws.
My CXF jaxws services are wrapped in Spring Boot 3.0. I also use
akarta.xml.bind-api 4.0.0 and org.eclipse.persistence.moxy 4.0.1.
I generate Java models with cxf-codegen-plugin with the following configuration:

Binding file has the following configuration:

xsiNilRepresentsNull=false)
</annox:annotate>
</jaxb:bindings>
</jaxb:bindings>
</jaxb:bindings>
Model class generation works fine, nullable properties are marked with
annotation:
"@XmlNullPolicy(nullRepresentationForXml =
XmlMarshalNullRepresentation.ABSENT_NODE, xsiNilRepresentsNull = false)".
To start Moxy Runtime use the following settings in main method of Application:
System.setProperty("jakarta.xml.bind.JAXBContextFactory",
"org.eclipse.persistence.jaxb.JAXBContextFactory");
I use this initialisation because I still need to use Spring Web Service Client
from Spring WS in parallel.
But on startup I get errors:

I have examined your code and found that you are using hard coded call to
"Class<?> factoryClass =
ClassLoaderUtils.loadClass("org.glassfish.jaxb.runtime.v2.ContextFactory" in
cxf-core org.apache.cxf.common.jaxb.JAXBUtils
I have experimented a bit and if you can make a few changes in two classes
everything will work. The classes need to be changed:
1. org.apache.cxf.common.jaxb.JAXBContextCache Method
getCachedContextAndSchemas in lines 197 to 194
old code
if (defaultNs != null) {
if (HAS_MOXY) {
map.put("eclipselink.default-target-namespace", defaultNs);
}
map.put("org.glassfish.jaxb.defaultNamespaceRemap", defaultNs);
}
new code
if (defaultNs != null) {
if (HAS_MOXY) {
map.put("eclipselink.default-target-namespace", defaultNs);
} else {
map.put("org.glassfish.jaxb.defaultNamespaceRemap", defaultNs);
}
}
2. org.apache.cxf.common.jaxb.JAXBUtils
2.1 Method getPostfix in lines 1105 to 1117
old code:
private static String getPostfix(Class<?> cls) {
String className = cls.getName();
//TODO: review and remove "com.sun" package name check
if (className.contains("org.glassfish.jaxb") ||
className.contains("com.sun.xml.bind")
|| className.startsWith("com.ibm.xml")) {
return "";
} else if (className.contains("com.sun.xml.internal")
|| className.contains("eclipse")) {
//eclipse moxy accepts sun package CharacterEscapeHandler
return ".internal";
}
return null;
}
new code:
private static String getPostfix(Class<?> cls) {
String className = cls.getName();
//TODO: review and remove "com.sun" package name check
if (className.contains("org.glassfish.jaxb") ||
className.contains("com.sun.xml.bind")
|| className.startsWith("com.ibm.xml") ||
className.contains("eclipse")) {
//eclipse moxy 4.0 accepts glassfish package
CharacterEscapeHandler see const SUN_CHARACTER_ESCAPE_HANDLER
// Const in MOXY 4.0.1
// SUN_CHARACTER_ESCAPE_HANDLER=
"org.glassfish.jaxb.characterEscapeHandler";
// SUN_JSE_CHARACTER_ESCAPE_HANDLER =

// SUN_CHARACTER_ESCAPE_HANDLER_MARSHALLER =

// SUN_JSE_CHARACTER_ESCAPE_HANDLER_MARSHALLER =

// part of setProperty(String key, Object value) from Class
org.eclipse.persistence.jaxb. JAXBMarshaller
// else if (SUN_CHARACTER_ESCAPE_HANDLER.equals(key)
|| SUN_JSE_CHARACTER_ESCAPE_HANDLER.equals(key) ||
//
SUN_CHARACTER_ESCAPE_HANDLER_MARSHALLER.equals(key) ||
//
SUN_JSE_CHARACTER_ESCAPE_HANDLER_MARSHALLER.equals(key)) {
// if (value == null) {
// xmlMarshaller.setCharacterEscapeHandler(null);
// } else {
// xmlMarshaller.setCharacterEscapeHandler(new
CharacterEscapeHandlerWrapper(value));
// }
return "";
} else if (className.contains("com.sun.xml.internal")
) {
return ".internal";
}
return null;
}
2.2 Method createContext in lines 1179 to 1202
old code:
public static JAXBContext createContext(final Set<Class<?>> classes,
final Map<String, Object> map)
throws JAXBException {
JAXBContext ctx = null;
try {
ctx = AccessController.doPrivileged(new
PrivilegedExceptionAction<JAXBContext>() {
public JAXBContext run() throws Exception {
//This is a workaround for CXF-8675
Class<?> factoryClass =
ClassLoaderUtils.loadClass("org.glassfish.jaxb.runtime.v2.ContextFactory",
JAXBContextCache.class);
Method m = factoryClass.getMethod("createContext",
Class[].class, Map.class);
Object context = m.invoke(null, classes.toArray(new
Class<?>[0]), map);
return (JAXBContext) context;
}
});
} catch (PrivilegedActionException e2) {
if (e2.getException() instanceof JAXBException) {
JAXBException ex = (JAXBException) e2.getException();
throw ex;
} else {
throw new RuntimeException(e2.getException());
}
}
return ctx;
}
new code:
public static JAXBContext createContext(final Set<Class<?>> classes,
final Map<String, Object> map)
throws JAXBException {
JAXBContext ctx = null;
try {
ctx = AccessController.doPrivileged(new
PrivilegedExceptionAction<JAXBContext>() {
public JAXBContext run() throws Exception {
String factoryClassName =
classNameFromSystemProperties("org.glassfish.jaxb.runtime.v2.ContextFactory");
//This is a workaround for CXF-8675
Class<?> factoryClass =
ClassLoaderUtils.loadClass(factoryClassName,
JAXBContextCache.class);
Method m = factoryClass.getMethod("createContext",
Class[].class, Map.class);
Object context = m.invoke(null, classes.toArray(new
Class<?>[0]), map);
return (JAXBContext) context;
}
});
} catch (PrivilegedActionException e2) {
if (e2.getException() instanceof JAXBException) {
JAXBException ex = (JAXBException) e2.getException();
throw ex;
} else {
throw new RuntimeException(e2.getException());
}
}
return ctx;
}
private static String classNameFromSystemProperties(String
defaultValue) throws JAXBException {
String factoryClassName =
getSystemProperty(JAXBContext.JAXB_CONTEXT_FACTORY, defaultValue);
if (factoryClassName != null) {
return factoryClassName;
}
return null;
}
private static String getSystemProperty(String property, String
defaultValue) {
String value = System.getProperty(property);
if (value != null) {
return value;
} else {
return defaultValue;
}
}
If you have other possibilities to configure org.eclipse.persistence.moxy. Can
you please describe.
Thanks in advance
