Passing Parameter to ad hoc view from BuiltInUserParameterProvider

[nageshit2011]

Hi,

I implemented ad hoc views & integrated in liferay using Iframe. Now i want to display data in the reports based on logged in user. So i implemented "CustomBuiltInUserParameterProvider.java". With hard coded "USER_ID" its working fine. Now i want to pass user data to "CustomBuiltInUserParameterProvider.java". But i dont have any idea, how to pass. Currently my data in liferay session.

Can u please guide me. Its urgent requirement for us.

Thanks & Regards,

VV Nagesh Bodapati.

Hi,

Find the below code,

 

public class LiferayUserProfileBuiltInParameterProvider implements BuiltInParameterProvider

{

 

  private static final String LOGGED_IN_USER_PARAMETER_PREFIX = "LiferayUser";

  private static final String[] LOGGED_IN_USER_STANDARD_PARAMETERS = {LOGGED_IN_USER_PARAMETER_PREFIX};

  

  @SuppressWarnings("unchecked")

  public List<Object[]> getParameters(ExecutionContext context, List jrParameters, Map parameters)

  {

    List userProfileParameters = new ArrayList();

 

    for (String parameterName : LOGGED_IN_USER_STANDARD_PARAMETERS) 

{

 Object[] result = getParameter(context, jrParameters, parameters, parameterName);

 if (result != null) 

 {

userProfileParameters.add(result);

 }

    }

 

    return userProfileParameters;

  }

 

  @SuppressWarnings("unchecked")

  public Object[] getParameter(ExecutionContext context, List jrParameters, Map parameters, String name)

  {

      if ((name == null) || (!name.toLowerCase().startsWith("LiferayUser".toLowerCase()))) {

          return null;

        }

      try

      {

          Authentication auth = SecurityContextHolder.getContext().getAuthentication();

          if ((auth == null) || (!(auth.getPrincipal() instanceof MetadataUserDetails))) 

          {

            return null;

          }

          MetadataUserDetails userDetails = (MetadataUserDetails)auth.getPrincipal();

          String userName = userDetails.getUsername();

          return new Object[] { JRQueryExecuterAdapter.makeParameter(name, LiferayUser.class), liferayUser };

      }

      catch(Exception exception)

      {

          System.out.println("Exception Occured in LiferayUserProfileBuiltInParameterProvider - "+exception.getMessage());

      }

      return null;

  }

 

  public String getLiferayUserParameterPrefix() 

  {

    return LOGGED_IN_USER_PARAMETER_PREFIX;

  }

}
