Hello, I am sorry if i didn´t put the topic in the correct place.
I download org.eclipse.birt.report.engine.emitter.nativexls_126.96.36.199110122114.jar and put it in eclipse\plugins\ folder and delete the org.eclipse.birt.report.engine.emitter.excel.config_myversion.jar
and org.eclipse.birt.report.engine.emitter.prototype.excel_myversion.jar. I did this because my XLS files were too big and it worked.
Then i put the org.eclipse.birt.report.engine.emitter.nativexls_188.8.131.52110122114.jar file in the C:\birt-runtime-3_7_2\ReportEngine\lib\. I then create it a script with genReport.bat in birt runtime 3.7.2 but it continue to generate large xls files. Then i try to extracted the org.eclipse.birt.runtime.version.jar comment the edited plugin.xml
<!--import from org.eclipse.birt.report.engine.emitter.prototype.excel
<extension name="excel emitter" point="org.eclipse.birt.report.engine.emitters">
The examples in that link are more directed to the Webviewer but i try to extract the org.eclipse.birt.report.engine.emitter.nativexls_184.108.40.206110122114.jar and copy the jar files in it
to C:\birt-runtime-3_7_2\ReportEngine\lib\ and nothing,
steal large xls files
