Hi there, I think jasperreports is a great tool but i've been dealing with this problem for a long time, i cannot get it to work with a jpa connection, ireport can't read the persistence.xml properly. In my previous projects i just used a plain jdbc connection and sql queries, then passing the hibernate underlying jdbc connection to the JasperFillManager instance. But now i need to use a jpa connection and ejbql. I added the "classes" folder (where the META-INF subfolder with the persistence.xml file is located) to the ireport classpath but when i specify my persistence unit name i get always the same mentioned error. I also added to the classpath the lib folder (with my current implementation of hibernate and jta) but i get the same result. I tried by creating a separate folder with a different version of the persistence.xml file, without using a jndi connection and setting transaction-type="RESOURCE_LOCAL". The same result. Any suggestion? Thanks in advance. Zeva.
