You can use the methods in this example to write security access expressions for objects.

The code uses a table called benefits to illustrate the results of specifying access control for an object. By default, this table has unrestricted access. You can use the SilverStream Management Console (SMC) to restrict access to the table, then log in as different users to test the results. For example, if you log in as a user without access, no data will appear in the table.

Getting the name of the current user   Top of page

The following code uses the getuser() method to determine the login identity of the current user. This method attempts to match the user login name to a user defined in SilverStream users and groups. If it does not find a match, it returns "Anonymous." The code uses setText() to set the results of getUser() to the text box lblUser.

  private void handle_btnGetUser_actionPerformed(ActionEvent evt) 

Determining if the current user belongs to a specified group   Top of page

This line of code specifes the group to which you want to compare the user to determine memebrship. It uses setText() to set the field fldUserInGroup to the group name "Administrators." The group specified must already be defined as a SilverStream group.

  protected void formLoaded() 

This code uses the userInGroup() method in a conditional statement to test for the group membership of the current Silverstream user. It then sets the test result to the text box lblUserinGroup.

  private void handle_btnUserInGroup_actionPerformed(ActionEvent 
        String userInGroup; 
        if (userInGroup(fldUserInGroup.getText())) 
          userInGroup = "true"; 
          userInGroup = "false";
