Hello, I am a new user of Flex 4 and have recently gone thru the training courses available here (Flex in a week). I have been tasked with moving some of our firm's webpages that use jsp and spring to connect to a mysql database to a flex frontend.
I've been looking over the BlazeDS tutorial (http://www.adobe.com/devnet/flex/articles/spring_blazeds_testdrive.html) and it seems rather helpful, but I could use some help in how to make a connection to a mysql database on an external server-- where does the connection info go, user name, password, etc.
In a nutshell, the application I am to design would need to be able to go out to a database to first verify user credentials, then to upload csv files and store the data into a database, and finally allow users to retrieve the data in datagirds and display in basic bar charts. Thanks to the training, I have a good understanding on using the datagrid, but the connecting to an external database is where I'm having trouble.
Also, I have seen a flex webpage where data is displayed in a chart and the user can export the chart as a jpg or export the input data to a csv file. Is anyone familiar with this capability?
Thanks for your help-- I am excited to learn all there is to know about Flex!
I would you should read the following link completely.
You need to create an Client/Server-application with 3-tiers client, application server (Java/Hibernate/Spring) and database server (MySQL for example).
Just buy a book over Flex and Java and read it.
