Support for Global Variables?

[umair]

Is there any support for Global Variables in Jasper Reports?

 

Like, if i want to retrieve the name of the user logged in..

Is this possible?

Try that :

 

<parameter name="LoggedInUser" isForPrompting="true" class="com.jaspersoft.jasperserver.api.metadata.user.domain.User"

 

and after in the definition of a Text Field :

 

$P{LoggedInUser}.getFullName()

 

(extract from French jasperserver forum: answer by Christopher André from Jaspersoft Corporation)

What i need is to transfer the user name of the user logged in Jasper Server to the report made by Jasper Reports.

How would i achieve that ?

In iReport, you edit your jrxml code. In the left frame, you add a parameter with name "LoggedInUser", you check the "Use as prompt" box and you put "com.jaspersoft.jasperserver.api.metadata.user.domain.User" in the combo parameter type (perhaps a problem with a class not found but don't care)

 

Then you add in your report a textField and you define its expression definition as "$P{LoggedInUser}.getFullName()"

 

When you run the report, the text field contains the logged user name.

Heres what i did,

View->Parameters->New

 

ParameterName: LoggedInUser

ClassType: String

UseAsPrompt: checked

 

Applied a Text Field with expression definition as "$P{LoggedInUser}.getFullName()".

Saved the report, uploaded the jrxml file and ran to see the following errors:

Umair,

I think your problem comes from the fact you defined the parameter type as "string" and not as "com.jaspersoft.jasperserver.api.metadata.user.domain.User" as said. This is not in the combo list : you must enter it by overwriting in the combo.

In my case, under iReport this class is not defined so you got a "Problem". But it is defined in jasperserver and if you run the report from jasperserver there is no problem. I tested on one report before posting my reply.
