Hi All,
There is a easiest way to access the parameters defined in a psml file.
In the portlet you just add the below code to read any parameter of
the psml file.
String textInPsmlFile = this.getAttribute("text");
I am assuing the parameter text is defined in the psml file as below:
<parameter name="text" value="this is the value I am looking in portelt"/>
Please let me know if this has answered your problem.
bye,
Bhaskar
