[BonitaStudio] Unable to delete process before starting

Hi everyone,

I'm in face of problem with my bonitaStudio (7.6.3).
I have make a process that i have launch lot of times. But now, BonitaStudio is unable to delete the previous definition, so i can't start my process...

That what i get in my log file:

Business Data Model - Text type - @Lob annotation

I have a BDM "Event" with a field "Note" type 'text'.
My db is PostgreSQL.
Bonita saves and reads correctly the data.

I have another web application with Hibernate.
I mapped the Event object with the same Bonita mapping.
Bonita mapping note with this annotation:

String note;

When I executed a HQL query
"select Note from Event"
in my application it returns a long value...I aspecting a String value!

Use of inbuilt Hibernate and Bitronix JTA

Hi there,

I would like to make use of the inbuilt Hibernate and Bitronix JTA for my own database.

I can see where the resources for the databases are defined in /bin/setenv.bat, /conf/bitronix-resources.properties and /conf/Catalina/localhost/bonita.xml but have no-idea how to do the database access portion of coding, does anyone have an example of java code to do this?

Accessing the datasource, reading a set of rows, inserting and updating a record.

Many thanks and best regards Seán
