[opencms-dev] How to login as "Guest"? getting CmsDbEntryNotFoundException

[Michael Kraus]

Dear all,

when I try to login as "Guest" (in order to perform a logout, as described on page 218 in the OpenCms 5 book), I get the following exception:

org.opencms.db.CmsDbEntryNotFoundException: User "Guest" was not found.
	at org.opencms.db.CmsDriverManager.loginUser(CmsDriverManager.java:3992)
	at org.opencms.db.CmsSecurityManager.loginUser(CmsSecurityManager.java:2773)
	at org.opencms.file.CmsObject.loginUser(CmsObject.java:1803)
	at org.opencms.file.CmsObject.loginUser(CmsObject.java:1785)
	at org.opencms.file.CmsObject.loginUser(CmsObject.java:1769)
	at org.apache.jsp.WEB_002dINF.jsp.offline.system.modules ...

The corresponding code is:

     CmsJspActionElement cmsJspActionElement = new CmsJspActionElement(pageContext, request, response);
     CmsObject cmsObject = cmsJspActionElement.getCmsObject();
     boolean logout = request.getParameter("logout") != null;

     if (logout) {
         cmsObject.loginUser(OpenCms.getDefaultUsers().getUserGuest(), "");
     }

In the Administration View, there exists a user "Guest" with no password. What am I doing wrong?

Kind regards,
	Michael
