### Hi,

In an OSGi context (Karaf 4.4.7), I’m encountering the following issue when instantiating `processEngineFactory`:

Code

```auto
Caused by: org.flowable.common.engine.api.FlowableException: no session factory configured for org.flowable.common.engine.impl.db.DbSqlSession
    at org.flowable.common.engine.impl.interceptor.CommandContext.getSession(CommandContext.java:280)

    at org.flowable.engine.impl.interceptor.CommandInvoker.executeOperations(CommandInvoker.java:128)
    at org.flowable.engine.impl.interceptor.CommandInvoker.execute(CommandInvoker.java:80)

```

The `ProcessEngineConfiguration` is created programmatically using `JtaProcessEngineConfiguration`, and the data source is directly injected into this configuration (`javax.sql.DataSource`).

Is there any specific configuration required to define the `JobDataManager` or to properly configure `MybatisJobDataManager`?

Thanks in advance for your help.

Best regards,
