You need to show us the relevant code which generated this error. Just posting a stacktrace is usually not enough information.Tim Biegeleisen
Hi Tim please see relevant codeJ1743
The Exception occurs in the MySQL Driver. Try to change the driver (update?) and disable the connection pool to isolate the source of the exceptiondrkunibar
Hi drkunibar i already using the latest my sql connecter, after removing the pooling connection i encounter the same thingJ1743
Hi Thank you for all your help. This issue is resolve now, its my wrong doing i forgot to remove this line -Djavax.net.debug=all in production server. :)J1743

I have got the same error with java.sql.SQLException: Too many tables; MySQL can only use 61 tables in a join

This occurs because of relating too many tables If you are not use fetch type It may occur because of relations

eg- In my case I have over 150 tables Book_Selling, Refund and etc. I create one table to connect all table regarding payment in that case If I get data from payment table it connect all other tables and as well as their related table so the count of this all tables exceeded 61 tables. In mysql default you can create only join query using 61 tables at a time

Use fetch type as lazy then it will solve your problem.
