language="java" erased or compile error

[glassner]

I tried to replace the language="groovy" specification in the xml file with langauge="java", but I get compilation errors with iReport 3.7.1.

How can I use language="java" without getting the compilation errors ?

 

Thanks !

Hi,

 

have you tried just removing the language attribute?.

 

Grettings.

[glassner]

Yes, I have tried to remove language="java" altogether, but I get lots of compile errrors.

[glassner]

there must be some property that must be set or a library that must be added for iReports to work with language="java" or without it ...

[glassner]

Here is the error I get if I set language="Java"

Have you set the language as "java" or "Java"?, can be a case mistake?

[rakeshenoch]

Easiest way is to right click on the report name -> Properties -> Scroll down to set the preferred language (Java, JavaScript or Groovy).

[glassner]

Followed your advice, but still errors. It seems that by setting language="Java", the report expressions would have to be rewritten differently.  Is the change from language="groovy" to language="java" expected to be seemless ?

Expressions written in Groovy remain invalid when you change the language to Java.

Please refer the following link to understand the difference http://jasperforge.org/uploads/publish/ireportwebsite/IR%20Website/iReport_groovy.html .

I think you'll have re-write the expressions in Java

[marjaneh]

Hi there, could you PLEASE help me here :
in iReport3.7.4
I found 2 places that we can set the language one of them is for each report in repot properties and one of them is report
default language in iReport ,
also there are 3 laguages that u can set (groovy,javascript,java) if u set it to groovy and javascript it would have language="groovy" or language="javascript"
and it keeps this after save but if u set it to java it doesn't have language="java" and if u yourself add it manualy it would be removed after each save again...so ur report has this error because the language is null
"javax.servlet.ServletException: au.com.rmt.ca.exceptions.SystemException: net.sf.jasperreports.engine.JRException: Language "javascript" not supported by this report compiler.
Expecting "java" instead.
