QUESTION
I would like to ask how to make Connection con = getConnection(); becaome a primer or main variable so that it would not connect to SQL database every function made. Because as you can see on my codes, every function/class has Connection con = getConnection(); so it connects to the database every function. It makes my program process slowly. Please help thank you.
...ANSWER
Answered 2020-May-13 at 11:51To solve your problem you need to store a Connection object in your sqltesting class as a class member. You then need to reference the Connection object instead of getConnection(). It's also worth mentioning that Connection is a AutoClosable object so you need to close this resource when you're done with it, I.E; on application disposal. You also might want to consider using a connection pooling API like Hikari or C3P0 so you can open and close connections when you need them instead of having 1 open for a long time.

...ANSWER
Answered 2018-Oct-12 at 08:28There are two reasons why is not returning anything.
Firstly, your template matches "/" which is the document node. This is the parent of the ns2:pointOfSale node in your XML. The document node does not have id as a child, so will not find anything. To fix this, you should match the root element (ns2:pointOfSale in this case) instead
