Using SessionContext

picture_as_pdf

We have developed an application that reviews all existing messages in an email account and displays the number of messages. The request is initiated at the client by clicking a button.

The call using a button is illustrated in Client Actions or Server Actions

The server action accesses the mail server; the required access data is obtained from the application configuration.

Sample code for the server action:

/**
 * Returns the number of mails from a preconfigured email account.
 *  
 * @return the number of mails
 */
public int getEmailCount()
{
   IConfiguration cfgSession = SessionContext.getCurrentSessionConfig();
 
   String sServer = cfgSession.getProperty("/application/email/server");
   String sPort = cfgSession.getProperty("/application/email/port");
   String sProtocol = cfgSession.getProperty("/application/email/protocol");
   String sUser = cfgSession.getProperty("/application/email/username");
   String sPwd = cfgSession.getProperty("/application/email/password");
 
   MailCheck mcheck = new MailCheck(sServer, sPort, sProtocol);
 
   return mcheck.getMails(sUser, sPwd).size();
}   

Excerpt from the configuration file:

  ...
  ...
 
  <email>
    <server>servername or ip</server>
    <port>110</port>
    <protocol>pop3</protocol>
    <username>username</username>
    <password>password</password>
  </email>
 
</application>

SessionContext can also be used for the following:

• Access session properties (e.g., application name, username, client properties)
• Request the name of the current action
• Access the server configuration
• Use of the direct server connection
• Add or remove objects related to a call
