------------------------------------
See here

As far as in the current camel-dozer component we cannot make it osgi compliant
due {{DozerBeanMapper}} being poorly configurable. So we cannot configure how
the mapping files should be loaded, by using a custom loader.
> OsgiDefaultCamelContext.getTypeConverterRegistry() returns null

> Key: CAMEL-3143
> URL: https://issues.apache.org/activemq/browse/CAMEL-3143
> Project: Apache Camel
> Issue Type: Bug
> Components: osgi
> Affects Versions: 2.4.0
> Reporter: Claes Redestad
> Assignee: Claus Ibsen
>
> The showed up when using dozer as shown in
> http://camel.apache.org/dozer-type-conversion.html, whose
> DozerTypeConverterLoader tries to get the type converter registry using:
> {{{TypeConverterRegistry registry =
> camelContext.getTypeConverterRegistry();}}}
> Plausible error:
> {code:title=OsgiDefaultCamelContext.java}
> @Override
> protected TypeConverter createTypeConverter() {
> return new OsgiTypeConverter(bundleContext, getInjector());
> }
> {code}
> {code:title=DefaultCamelContext.java}
> public TypeConverterRegistry getTypeConverterRegistry() {
> if (typeConverterRegistry == null) {
> // init type converter as its lazy
> if (typeConverter == null) {
> getTypeConverter();
> }
> // type converter is usually the default one that also is the
> registry
> if (typeConverter instanceof DefaultTypeConverter) {
> typeConverterRegistry = (DefaultTypeConverter) typeConverter;
> }
> }
> return typeConverterRegistry;
> }
> {code}
> Error:
> getTypeConverter() returns an OsgiTypeConverter
> OsgiTypeConverter does not inherit from DefaultTypeConverter, thus the
> instanceof returns false
> => null is returned
> Solution:
> Lots of different ways to do this, and it's getting late here. In this case,
> maybe it's OsgiDefaultCamelContext's responsibility to also override
> getTypeConverterRegistry with something along the lines of:
> {code}
> @Override
> public TypeConverterRegistry getTypeConverterRegistry() {
> if (typeConverterRegistry == null) {
> // init type converter as its lazy
> if (typeConverter == null) {
> getTypeConverter();
> }
> // type converter is usually the default one that also is the
> registry
> if (typeConverter instanceof OsgiDefaultTypeConverter) {
> typeConverterRegistry = ((OsgiDefaultTypeConverter)
> typeConverter).getRegistry();
> }
> }
> return typeConverterRegistry;
> }
> {code}
> We've employed an (ugly) workaround in a local version of
> DozerTypeConverterLoader.java:
> {code:java}
> TypeConverter typeConverter = camelContext.getTypeConverter();
> DefaultTypeConverter registry = null;
> if (typeConverter instanceof DefaultTypeConverter) {
> registry = (DefaultTypeConverter)typeConverter;
> } else if (typeConverter instanceof OsgiTypeConverter) {
> OsgiTypeConverter osgiTypeConverter =
> (OsgiTypeConverter)typeConverter;
> registry = osgiTypeConverter.getRegistry();
> }
> {code}
