BIRT Runtime 2.3.2.2 not working with JDK 1.4

Gnana

Hi,

I am creating a java application to generate reports and I am using birt-runtime-2_3_2_2 report engine. It is mentioned that the Pre-requisites for this runtime is: Java 1.4/1.5 JDK/JRE.

The problem is I am getting a "java.lang.UnsupportedClassVersionError" when I run using JDK 1.4. But the same works using JDK 1.5. My project uses JDK 1.4 and reports are to be generated using JDK 1.4 only.

Please let me know if that is a bug in the birt-runtime-2_3_2_2 release or is there some configuration that i might have missed out.

java.lang.UnsupportedClassVersionError: org/eclipse/birt/core/exception/BirtException (Unsupported major.minor version 49.0)

Gnana,

I need to update the website, but 2.3.2 requires Java 1.5.
