I would fetch the data when the server session is created in: ServerSession.execLoadSession()
If the amount of data is not to big (few values), it make sense to put it in the shared context variable map of the Session you will be able to read it from the client
Here an example with one String value called UserInfo:
@Override
protected void execLoadSession() throws ProcessingException {
LOG.info("created a new session for " + getUserId());
String userInfo = .. ; //Do something to initialize the value.
setUserInfo(userInfo);
}
On the Server Session, you need to provide a getter and a setter like this:
/**
* @return the userInfo from the shared context
*/
public String getUserInfo() {
return getSharedContextVariable(USER_INFO, String.class);
}
/**
* @param userInfo
* the userInfo to set into the shared context
*/
public void setUserInfo(String userInfo) {
setSharedContextVariable(USER_INFO, String.class, userInfo);
}
In the client session you can add the getter:
/**
* @return the userInfo
*/
public String getUserInfo() {
return getSharedContextVariable(USER_INFO, String.class);
}
To be correct, the USER_INFO constant should be shared between the client and the server. You can put this on some interface in the shared plugin. If you do not so (like in my case) you have the same constant defined twice.
After this, you can read the user info in the Client Session:
@Override
public void execLoadSession() throws ProcessingException {
//...
System.out.println("User Info" + getUserInfo());
}
Or from anywhere in the client:
MessageBox.showOkMessage("Client Session User Info", ClientSession.get().getUserInfo(), null);
I hope it help you to start.
