javax.persistence.TransactionRequiredException: no transaction is in progress

Please help with the below issue, Everyone seems to have the same kind of problem. I did read through the forum but couldn't find the solution. What ever solutions have been posted i tried couple of them

Removing the @Service declaration from serviceimpl class and declaring it in servlet-config.xml, but my project won't compile. Not sure what is causing this issue.

I am using STS tool, trying to insert the data in the table, but encountered below problem. If I remove the em.flush() then there is no exception but it doesn't save in the database. I have attahe entire package of mine for ref.

Exception
