Tech stack: java, sql
Domain: databases

Research direction

Start with the SQL Server CDC JSON example and trace class loading from com.dtstack.chunjun.util.DataSyncFactoryUtil.java:70, especially discoverSource. Investigate why com.dtstack.chunjun.connector.sqlservercdc.source.SqlservercdcSourceFactory is not found, then verify that the example can resolve the source factory without the reported ClassNotFoundException.
