Differences with the Java Reporting Engine

Although there are clear advantages to having a 100% pure Java reporting engine, the developers at Business Objects had to rewrite it from scratch. Anytime a large software component such as the Crystal Reports engine is rewritten, there are bound to be some differences, at least in the first version. Some of those differences are conscious decisions made by Business Objects to limit the scope of the development to meet the target release date. Other differences surface because of development platform differences: Java versus native Windows. The result is that some features are not currently supported by the report processing engine included with the Java Reporting Component. The following sections address some of these issues.

Supported File Formats

The first and most important limitation is that only version 9 and 10 report files are supported. This doesn't mean that reports designed in version 8.5 or earlier are useless, but it does mean they have to be converted to version 9. To make this process easier, you can download a Report Conversion Utility from the Business Objects Web site. It can open up reports in batch, make any necessary changes, and save them into a version 9/10 file format. New reports can be created using the standard Crystal Reports 10 designer.
