BIRT - Passing Report URL parameters to DataSource URL

Question

I have two servers - one for application(Apache http) and another for BIRT reporting (tomcat). I will have BIRT reports designed with XML Schema files, wherein Datasource URL will be given as

http://localhost/myApp/index.php

Now, the actual URL to access report is as below

http://localhost:8080/birtviewer/frameset?__report=DummyOrder.rptdesign

Now, when is pass a parameter in the Report URL, it should be passed to the Datasource URL, as below:

Report URL: http://localhost:8080/birtviewer/frameset?__report=DummyOrder.rptdesign&OrderNo=101
DataSourceURL: http://localhost/myApp/index.php?OrderNo=101

Is there a way to achieve this??

Answer 1

Double click on your XML-Data-Source and select "property binding" on the left. Enter a function in to the "XML data source file:" field like below:

if (params["OrderNo"] != null){
 "jdbc:mysql://localhost/myApp/index.php?OrderNo=" + params["OrderNo"];
}else{
 "jdbc:mysql://localhost/myApp/index.php";
}

There is also a section in the birt wiki on how to change the data source at runtime.
