Extracting loggedinuser information in jasperserver 4.0

[mandm]

  Here is how my report looks, i have highlighted the code in red. It does not work on ireport 4.0 (giving an error for java.lang.classnotfoundexception: com.jaspersoft.jasperserver.api.metadata.user.domain.User)

and on jasper server 4.0 it just says report is empty and no errors in the catalina.out

can you please let me know what i am missing?
