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
* Get report locale in string.
	 * 
	 * @param request
	 *            http request
	 * @return report String

	public static String getLocaleString( HttpServletRequest request )
	{
		return getParameter( request, PARAM_LOCALE );
	}

	public static int getPage( HttpServletRequest request )
	{
		int page = getParameterAsInt( request, PARAM_PAGE );
		if ( page > 0 )
			return page;
		String servletPath = request.getServletPath( );
		if ( IBirtConstants.SERVLET_PATH_FRAMESET
				.equalsIgnoreCase( servletPath )
				&& PARAM_FORMAT_HTML.equalsIgnoreCase( getFormat( request ) ) )
		{
			page = 1;
