Jakarta Compatibility? about jasperreports HOT 2 CLOSED

The Jakarta Migration does not concern all aspects of our library. It only affects certain features that make use of Java APIs which are part of the Jakarta Migration project.

These APIs that we use and are subject to the migration are:

• servlets
• EJBQL query executer
• HQL query executer (Hibernate)

In order to support these features in both flavours going forward: Java EE (deprecated) vs Jakarta EE (new), we had to take these features out of the core library and implement them twice. This is why we now have new artifacts such as:

• jasperreports-servlets.jar (jakarta)
• jasperreports-serverts-j2ee (deprecated)
• jasperreports-ejbql.jar (jakarta)
• jasperreports-ejbql-j2ee.jar (deprecated)
• jasperreports-hibernate.jar (jakarta)
• jasperreports-hibernate-j2ee.jar (deprecated)

Because the Jakarta migration of these features required us to take them out of the core library, we took the opportunity and further split the library into a core and several other optional artifacts that provide specific features and require certain third-party dependencies.
This split into multiple modules helps with dependency management as each feature brings its own mandatory dependencies and users would be able to select only the features they need in their applications.

Separating features into optional modules also required us to change some of the package names and we'll soon provide a list of API changes that have been performed with this occasion.

What I am saying is that you should expect API changes when you upgrade to JasperReports version 7 and you should change your code to adapt to these. Most of the changes are about package names and method names that lost some suffix which was a reminiscence of past refactorings in the project's long history.

The biggest change however is the breakage of the JRXML backward compatibility. We adopted Jackson XML as loader/writer of our report template file format (.jrxml files) and external style template file format (.jrtx files).
Converting these files to the new format can be performed with Jaspersoft Studio, but this will only be available in the upcoming 7.0.0 release of the designer tool which is currently in preparation.

Release 7.0.0 snapshot artifacts are now available on our public repository at:
https://jaspersoft.jfrog.io/artifactory/jr-ce-snapshots/

I hope this helps.
