Hello there,

I am currently following this tutorial:  
[http://www.flowable.org/docs/userguide/index.html#\_xml\_based\_mapped\_statements](http://www.flowable.org/docs/userguide/index.html#_xml_based_mapped_statements)

…but for some reason, getDbSqlSession() is undefined:  
 ![Screenshot at 2017-09-14 12-58-27](https://cdck-file-uploads-canada1.s3.dualstack.ca-central-1.amazonaws.com/flex035/uploads/flowable/original/1X/eaf078ec0de543bb73b68bbfd7ad5a2af820157f.png)

So I tried to check what else are available but seems there is none applicable to what I’m trying to achieve.

Any help is appreciated. Thank you.

Hi,

Please check following jUnit test in the flowable source  
org.activiti.standalone.cfg.CustomMybatisXMLMapperTest

That’s a working example how it works.
