To fix this issue We can use PGObject and Jackson Object mapper to save the json in Postgres
code :
val person=PGobject()
person.type="jsonb"
person.value=ObjectMapper.writeValueAsString("{"fname":"john","lname":"doe"}")

it should still fix some issue Reading and writing PostgreSQL JSON columns works in Apache Cayenne out of the box. You can map them as String attributes on the Java end. But that's pretty much it. No special magic. I just tried the following using GitHub master version (Cayenne 4.0) and PostgreSQL 9.5 Docker image:
code :
CREATE TABLE json_test (
    id SERIAL,
    x json
);
ObjectContext context = ...
JsonTest t = context.newObject(JsonTest.class);
t.setX("{\"m\":1}");
context.commitChanges();

List<JsonTest> list =
     ObjectSelect.query(JsonTest.class).select(context);

Any of those help May be the driver used in Designer is different from the one you copied to your viewer. In your eclipse plugin directory you will find org.eclipse.birt.report.data.oda.jdbc_4.4.1.v201408290142 folder which contains the jdbc driver for your report. Copy and paste it to WEB-INF/lib folder. That would work hopefully. Good luck!!

will be helpful for those in need PostgreSQL has the json and jsonb (b for binary) data types. You can use these in your table definitions just like any other data type. If you plan to merely store the json data then the json data type is best. If, on the other hand, you plan to do a lot of analysis with the json data inside the PG server, then the jsonb data type is best.
