I would like to create a basic rest service. At first I would like this service to validate the JSON that comes in. How do I do that?
First component would probably be tRestResponse what about after that?
Use a tJava or tJavaRow and load a Java JSON Schema Validator library. Something like that https://github.com/java-json-tools/json-schema-validator/blob/master/src/main/java/com/github/fge/js...
Another way with limitations: Talend Document object type can translate the JSON to XML if it is in a supported format in XML, and then use tXSDValidator. However, if your JSON is very complex, with arrays, nodes with digits only, etc, you will need to use a library like above.
I thought I can use standard components. I don't really want to Validate JSON against a schema but just to validate that it is a valid JSON.
