Reading cookies

vlodha

How can I validate whether a cookie is present or not in BIRT report initialization? I want to check if "USER" cookie is present then only report should be accessible else redirect to error page.

Hi vlodha:
Are your using the BIRT sample viewer? If so then use the following script in beforeFactory:

var request = reportContext.getHttpServletRequest();
cookies = request.getCookies();

Now you can iterate through the cookies to get the value of "USER" cookie.

I am able to read the cookies but how do I redirect to error page ?

In my XML file am adding following:

<method name="beforeFactory"><![CDATA[
var request = reportContext.getHttpServletRequest();
var cookies = request.getCookies();
var i =0;
var flag = 0;
do{
if(cookies[i++].getName().equals("USER")){
flag = 1;
}
}while (i < cookies.length)

if(flag != 1){

//redirect to error page....

}

]]></method>

If you want to redirect to an error page, you should perform your check outside of the BIRT Report. One way of doing this would be with a ServletFilter. 
 
You could also have some script in your report to simply show a message to the user that they don't have access. 
 
Alternatively, the Actuate BIRT Viewer has a security extention point that allows you to integrate the viewer with your application to offer users a seemless experience. You can see more about this extension point here:
