BIRT 2.3.2 to 2.6.0 upgrade error

Question

I am getting the following error when I try to upgrade the BIRT version that is embedded in my custom web application

java.lang.NoSuchMethodError: org.eclipse.birt.report.engine.api.EmitterInfo.<init>(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/Boolean;Ljava/lang/Boolean;Lorg/eclipse/birt/core/framework/IConfigurationElement;)V

at java.security.AccessController.doPrivileged(Native Method)
at org.eclipse.birt.report.engine.api.impl.ReportEngineFactory.createReportEngine(ReportEngineFactory.java:14)

The error occurs in the following line in the code

birtEngine = factory.createReportEngine(config);

I have checked the Web App Libraries and I have the 2.6.0 runtime lib jars in it.

Please help
