Call Jasper report using a link

In previous post jasper report is called with the help of java bean. Now we can use a link to call report as in previous method calling report from a .jsff page gives error.

To call report using link follow following steps: 

• Add a go link to page which will call servlet and also pass parameters.
• Add a command button to assign value to parameters.
• Add value in destination like “/jasperservlet?deptno=#{bindings.DepartmentId1.inputValue}&reporttype=#{bindings.Filetype1.inputValue}”.
• Here deptno and reporttype are parameters passed from url and will be used in servlet.
• To get parameter value in servlet use following code.

Integer code = Integer.valueOf(request.getParameter("deptno"));
String reporttype = request.getParameter("reporttype");
