Method Summary

protected ClusteredHTTPSessionBusiness createSession(String id, SerializableHttpSession session)


protected String encode(byte[] data)
          Encode the bytes into a String with a slightly modified Base64-algorithm This code was written by Kevin Kelley and adapted by Thomas Peuss

protected String generateSessionId()
          Generate a session-id that is not guessable

protected MessageDigest getDigest()
          get a MessageDigest hash-generator

SerializableHttpSession getHttpSession(String sessionId, ClassLoader tcl)
          Return the HttpSession associated to a session id.

protected Random getRandom()
          get a random-number generator

String getSessionId()
          Generates a new session id available cluster-wide

long getSessionTimeout()
          Indicate the duration, in ms, after which the session can be cleaned if no access occurs.

boolean getUseLocalBean()


protected void initRefToBean()


void removeHttpSession(String sessionId)
          Remove an HttpSession from the cluster (log off for example)

void setHttpSession(String sessionId, SerializableHttpSession session)
          Associate a new session with the session id.

void setSessionTimeout(long miliseconds)
          Indicate the duration, in ms, after which the session can be cleaned if no access occurs.

void setUseLocalBean(boolean useLocal)
          Indicates whether the service should use the local and home interfaces of the entity bean or the remote and remote home interfaces (depending if they are in the same JVM).
