Need Help with jsp in Eclipse talking to MySQL database
I have this skeleton Framework for a jsp server app in Eclipse running tomcat 6.x and external MySQL server.
After some initial tweaking this seems to at least run without errors, suggesting that I am connecting to the database. I did, however, have to add the following two .jar files to the Referenced Libraries path in my project. Is it normal to have to do that? Can I not add these to the eclipse libraries or plug-ins so that I won't have to add them for each application that uses MySQL, and why do I have to add aspectj-1.5.3.jar. It seems that this is necessary.
mysql-connector-java-5.1.5
aspectj-1.5.3.jar
My main question is:
How can I verify that the database connection is working and what other code can I use to test the driver (i.e. insert, removing, joining, etc). With the way I have it configured it seems to be connecting but I'm not getting any output despite a non-empty database.
I do have the ability to create and manipulate a database using phpmyadmin or similar tool, so I would appreciate some instructions on how to set up a test database and how to access it via the .jsp page using struts and or java code.
Thanks.
