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
return fileName;
	}
	/**
	 * Generates a file name for output attachment.
	 * 
	 * @param request
	 * @param format
	 * @return the file name
	 */
	public static String generateFileName( HttpServletRequest request,
			String format )
	{
		String baseName = null;
		BaseAttributeBean attrBean = (BaseAttributeBean) request
				.getAttribute( IBirtConstants.ATTRIBUTE_BEAN );
		if ( attrBean != null )
		{
			baseName = attrBean.getReportDesignName( );
			if ( baseName == null || baseName.length( ) == 0 )
				baseName = attrBean.getReportDocumentName( );
		}
		String fileName = generateFileNameWithoutExtension( baseName );
		
		String extensionName = getExtensionName( format );
		if ( extensionName != null && extensionName.length( ) > 0 )
		{
			fileName += "." + extensionName; 
		}
		return fileName;
	}
