Servlet Mappings
The BIRT Web Viewer consist of two main Servlets, the ViewerServlet and the BirtEngineServlet. These Servlets handle three mappings: ( /frameset, /run, and /preview).

The /frameset mapping renders the report in the full AJAX viewer complete with toolbar, navigation bar and table of contents features. This mapping also generates an intermediate report document from the report design file to support the AJAX based features.
eg http://localhost:8080/viewer/frameset?__report=myreport.rptdesign&parm1=value1

The /run mapping runs and renders the report but does not create a report document. This mapping does not supply HTML pagination, TOC or toolbar features, but does use the AJAX framework to collect parameters, support report cancelling and retrieve the report output in HTML format.
eg http://localhost:8080/viewer/run?__report=myreport.rptdesign&parm1=value1

The /preview mapping runs and renders the report and does not generate a report document, although an existing report document can be used in which case just the render operation occurs. The output from the run and render operation is sent directly to the browser.
eg http://localhost:8080/viewer/preview?__report=myreport.rptdesign&parm1=value1



如果你想重用某一个报表，在新的报表中修改分组group时，修改该分组的分组依据 "group on"即可，切记不好去修改该group的name；因为如果修改了该group的name，则table中所有参照了该group（是以group的名字为参照的）的数据项都会报

Group "groupname" used in xxx does not exist

奇怪的birt问题：
在dataset的script中通过以下语句做report parameter是否为空的判断：

var sql = this.queryText;
var province = params["province"];
if(province!=null && province!="") {
	var replaceStr=" T.PROVINCE='" + province + "'";
	sql=sql.replace("1=1",replaceStr);
}
this.queryText = sql;

参数province不为空时，在dataset的“Preview Results”中出的来预览结果；但当参数province为空时，在dataset的“Preview Results”中出不来预览结果，不知何故；
改用下面的方法后，不管province是否为空在dataset的“Preview Results”中都可以出预览结果：

var sql = this.queryText;
var province = params["province"].value;
if(province) {
	var replaceStr=" T.PROVINCE='" + province + "'";
	sql=sql.replace("1=1",replaceStr);
}
this.queryText = sql;
