Swagger translator bugs and enhancement request ----------------------------------------------- Key: TEIID-4326 URL: https://issues.jboss.org/browse/TEIID-4326 Project: Teiid Issue Type: Bug Components: Misc. Connectors Affects Versions: 9.0, 9.0.1 Environment: Windows 7 x64 Java 8 Reporter: Van Dillon Assignee: Ramesh Reddy This JIRA is in response to instructions from Ramesh Reddy in the teiid-dev mailing list (http://lists.jboss.org/pipermail/teiid-dev/2016-July/000997.html) Bugs 1) JsonSerializer.deserialize with an unnamed array If a Rest endpoint is called that returns an unnamed array such as: [ { "scheduleId": 10007, "timeStamp": 1468000572174, "value": 2813018112 }, { "scheduleId": 10007, "timeStamp": 1468000602173, "value": 2817523712 } ] the JsonSerializer.deserialize method throws an EmptyStackException in the END_ARRAY case because the 'fieldName' stack is empty. A check for empty in the if clause fixes the problem: if (arrayLevel > objectLevel && !fieldName.empty())... 2) DDL generation When the schema DDL is generated from the Swagger, all procedure parameters have their NullType set to NullType.No_Nulls. Can this be set depending on the Swagger parameter 'required' field? For instance: boolean required = parameter.getRequired(); pp.setNullType(required ? NullType.No_Nulls : NullType.Nullable); Enhancement idea: REST apis that are not Swagger based could be used with the Swagger translator if a user could provide a swagger.json file they've created in the Swagger Editor. I've added some changes to SwaggerMetadataProcessor that allow a user to specify an importer property, swaggerFilePath, that's used in the getSchema method to load the Swagger metadata from file.
