Example 1 with TypeConverterLoader

use of org.apache.camel.spi.TypeConverterLoader in project camel by apache.

the class OsgiTypeConverter method createRegistry.

protected DefaultTypeConverter createRegistry() {
    // base the osgi type converter on the default type converter
    DefaultTypeConverter answer = new DefaultTypeConverter(new DefaultPackageScanClassResolver() {

        @Override

    }, injector, factoryFinder);
    // inject CamelContext
    answer.setCamelContext(camelContext);
    try {
        // only load the core type converters, as OSGi activator will keep track on bundles
        // being installed/uninstalled and load type converters as part of that process
        answer.loadCoreTypeConverters();
    } catch (Exception e) {
        throw new RuntimeCamelException("Error loading CoreTypeConverter due: " + e.getMessage(), e);

        ArrayList<ServiceReference<TypeConverterLoader>> servicesList = new ArrayList<ServiceReference<TypeConverterLoader>>(Arrays.asList(serviceReferences));
        // Just make sure we install the high ranking fallback converter at last
        Collections.sort(servicesList);
