transaction management in liferay mvc portlet class

[francesco scamarcio, modificado hace 10 años.]

hi,

I have developed a portlet with liferay portlet mvc. I created two ENTITIES A and B and each of these entities has a method to add data into it tables.
As I can handle transactions in liferay from the controller class method if one of the two portlet fails?

If you used service builder, transactions are managed at the service tier and are done through the method names (those prefixed w/ obvious changing words such as "add" or "delete" will be wrapped in a regular txn, non changers like "get" will be wrapped in a read only txn).

thank you David,

my question is if i hae to call two entities method in a controller how can i manage the two call with a unique transaction? is posible to do that in a controller method? or the transaction is only applied to service tier?

Hola Francesco,

did you try adding a method for this purpose in one entity xxxServiceImpl and adding reference for other entitiies in service.xml? After ServiceBuilder is executed, there will be some available references for those entities services/persistence classes.

Then you can use this method (transaction aware) from your portlet class.
