    CmsJspActionElement cms = new CmsJspActionElement(pageContext,request,response);

//  CmsObject cmsObject = cms.getCmsObject();
    cmsObject.loginUser("Admin", "admin");

Answer 1

there is a module to do that, have you try it?
opencms 8 http://www.alkacon.com/en/modules/downloads/oamp-webuser_2.0.0.html
opencms 7 http://www.alkacon.com/en/modules/downloads/oamp-webuser-0.9.0.html

Answer 2

There are 4 arguments in CreateUser method in 'CmsObject' class:

CmsUser createUser(String name, String password, String description, Map<String, Object> additionalInfos);

And Password at lest 4 characters. That's required in OpenCms System. You should change password: 1234

CmsUser user = cmsObject.createUser("John","1234","Programmical Instructions", null);
