Checked and modified the web application for fixing the inserting of special characters in JDA, as per checking, the web application is sending the data as is, meaning there are no added characters on it, but it is still not inserted in JDA. Modified the web application to change the way it is inserting the data in JDA, and tested the changes, and as per testing, the same error is encountered. Will continue to check and modify the query for inserting the data with special characters in JDA.
