Hi,

The MySQL support can be considered stable.
It's quite easy to add Activiti to an existing web application. You just have to copy the Activiti Engine JAR and its dependencies. Then you also need to start the Activiti Engine, which is explained in the userguide.
When you need more detailed info you can read my book, Activiti in Action, which explains how to use Activiti in an existing web application.

Best regards,

>>The MySQL support can be considered stable.

Does this mean the support of MS SQL is not? The reason why I am asking this the system to which we are adding a workflow process is an existing system that has been around since early java days and which uses MS SQL server.

Also, can multiple process engines each using same or different process flow (one per customer ) be instantiated and used within the same web application?

Thanks

Hi,

Sorry, I misread the database type. Yes MS SQL can also be considered stable, at least for 2008 and later.
You can use multiple process engines which share the same database. Then they also have the same process definitions available.
When you want to use a web application with multiple process engines, you can use a load balancer in front of the process engines. That should work fine.

Best regards,

Tijs, I purchased the book via the MEAP. It has till the 12th chapter, are the remaining chapters available for download?

BTW, It would be helpful if you could provide a comment section on the book's site http://www.bpmnwithactiviti.org which can be used for any book related Q&As.

Thanks
