hi
i wanted to list out list of java classes, where the connection/preparedstatement open. Is there any readymade java code/tool available to check in the DAO package.

Thanks inadvance

classes? Do you mean instances, or are you only looking for a way to parse classes and find out where a JDBC connection may be opened?

You could perhaps use javap to disassemble the classes. This might enable you to find classes where the Connection.close method was not called. But just because a class contains a call to Connection.close, that doesn't mean the call is actually executed reliably and correctly at run time. There isn't any automated way to determine that.

So you might be better off just doing a source-code search to identify the classes where connections are created, then have a person look at each of those classes.

Opening and closing connection in each class is a bad idea as it will lead to degraded performance.

To find the connection not closed do text search on your code.
