Configuring a connection to MySQL

I have installed lcds es trial version 2.6.1 with tomcat option. When I run the test of the installation it works OK.

Now I want to make a connection to a MySQL database to access it through a flex program with data service.  The first thing I'm doing is preparing a folder where define the connection.  I copied the c:\lcds\tomcat\webapps\lcds in C:\lcds\tomcat\webapps\foed, assuming that with this there shouldn't be a problen.  Then, when I run lcds with tomcat appears errors.  When I follow creating the options in the data-management-config.xml its turns worst.

I'm looking for a way to connect lcds to MySQL but I can't find it.  I need help configuring the access to MySQL.

Thanks.

Rodolfo.

Hi,

you can not access the MySQL database directly with flex (like php).

You need to access it via a Java Assember (Custom, SQL, Hibernate, Fiber Assembler) that transfers the data via AMF  ( with BlazeDS/LCDS) to Flex.

So how do you want to access the data, with BlazeDS, with LCDS

and which assembler do you want to use: SQL Assember,  Hibernate Assember, Fiber Assembler ...?

Hi,

there is a nice example of hibernate in the lcds-examples. They are created with the setup with tomact.

There are several tutorials, google for "Hibernate Flex", for example:

http://fleksray.org/flex_datamanagement_service_hibernate_en.html

The hibernate.cfg.xml for MySQL ist attached below.

Fiber is only part of the new lcds3b1 and Flashbuilder 4b1:

There are nice tutorials under

http://labs.adobe.com/technologies/livecycle_dataservices3/videos/

If you look for very simple connection to mysql you can take a look at

All the best!

I Think if using LCDS 3 , Fiber is no1. Because it's easy , visualization and commercial .Now, i'm trying to intergrate BlazeDS + Spring + Hibernate + MySQL (100% OpenSource). I have already configured BlazeDS 3.2 + Spring 3.M3 + MySQL and i don't know how to config Hibernate to work with them. Can u help me?
