Bug 211081 log4j not working with preview
I am using log4j in the scripting Database source. I place my log4j-1.2.15.jar file in the folder C:\eclipse\plugins\org.eclipse.birt. report.viewer_2.2.1.r22x_v20070920\ birt\WEB-INF\lib However when I try to preview I get an error Http Status 500. When I check the log files I see the following exceptions java.lang.NoClassDefFoundError: org/apache/log4j/Category
viewer/org.eclipse.birt.report.viewer/birt/WEB-INF/classes/org/eclipse/birt/report/utility/ParameterAccessor.java
