[opencms-dev] Accessing OpenCMS from a standalone java application

[Jaisy Ann Cheriyan]

Dear

             Please have a look at the java files written so as to
access OpenCMS contents



public class FetchData {



            public static void main(String[] args){



                        try{

                                    String loggedUser;

                                    MyCmsShell shell = new MyCmsShell
("C:/ApacheTomcat/Tomcat 5.0/webapps/opencms/WEB-INF", null, null);

                                    CmsObject cms =
shell.getOpenCmsObject();

cms.loginUser("Admin", "admin");

                       }



                        catch(Exception exp){

                                    System.out.println("Exception!!" +
exp);

                                    exp.printStackTrace();



                        }

            }



}



public class MyCmsShell extends CmsShell

{

  public MyCmsShell (String webInfPath, String servletMapping, String
defaultWebAppName)

  {

    super (webInfPath, servletMapping, defaultWebAppName, "", null);

  }



  public CmsObject getOpenCmsObject()

  {

    return m_cms;

  }





And the error that is happening is



C:\OpenCMSenter>java FetchData

log4j:WARN No appenders could be found for logger (org.opencms.init).

log4j:WARN Please initialize the log4j system properly.

OpenCms WEB-INF path:  "C:/ApacheTomcat/Tomcat
5.0/webapps/opencms/WEB-INF".

OpenCms property file: "C:\ApacheTomcat\Tomcat
5.0\webapps\opencms\WEB-INF\confi

g\opencms.properties".
