Could not load the property file output_xml.properties for output method xml

[ganeshmca]

When Transformer new instance is created I am getting a runtime exception, any solutions or workaround ?

Exception
2018-05-10 09:58:19.278339+0530 LumifyIOS[58056:5630921] *** Terminating app due to uncaught exception 'OrgApacheXmlSerializerUtilsWrappedRuntimeException', reason: 'org.apache.xml.serializer.utils.WrappedRuntimeException: Could not load the propery file 'output_xml.properties' for output method 'xml' (check CLASSPATH)'

JavaCode
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();

J2OBJC Code
JavaxXmlTransformTransformerFactory *transformerFactory = JavaxXmlTransformTransformerFactory_newInstance();
JavaxXmlTransformTransformer *transformer = [((JavaxXmlTransformTransformerFactory *) nil_chk(transformerFactory)) newTransformer];

The Xalan serializer has properties files that need to be included with your app as Java resources. There are seven files in the org/apache/xml/serializer directory, so as the Java resources page directs, all of them need to be copied into an org/apache/xml/serializer Resources sub-directory.

I'm leaving this issue open, as we should be able to copy the properties file data into default tables in the OutputPropertiesFactory, so there is a backup when those property files are not present (rather than throwing a WrappedRuntimeException).

Thanks, After adding those files that error is solved and I have started getting this exception in the last line, please suggest anything more to be added

Exception

TransformerFactory transformerFactory = TransformerFactory.newInstance();

transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

transformer.transform(source, result);

This is solved after adding this line.
transformer.setOutputProperty(OutputKeys.METHOD, "xml");

Added support for apps that fail to correctly link in Xalan resource files. If a resource is not found, a string containing the same data as the resource file is loaded instead. To use this before the next release (not scheduled), build j2objc from source and use that source's dist/lib as the library path to j2objc libraries.
