JPAContainer performance issue
Hi folks,
I am facing serious performance problem of data retrieving and writing ( from mySQL via JPAContainer) in UI. Please help out. I am using vaadin 7. Tomcat is my app server.
Regards,
AnuraJH
Hi,
It is pretty impossible to say what is wrong with the details you gave, but my suggestion is to avoid using JPAContainer alltogether. Using JPA directly (via some service class, e.g. stateless EBJ) with Vaadin is just as easy with simple cases and much easier in complex cases. If you need "lazy loading" to your Table, see MTable in Viritin.
cheers,
