protected void addJSFActionListeners()

Adds the server actions that are needed by various client-side interactions.

This method registers an instance of the following listeners:

• IlvFacesDiagrammerSelectAction
• IlvFacesDiagrammerSelectRectAction
• IlvDiagrammerCreateActionListener

Since:

findFile

protected String findFile(String file)

isSessionExpired

protected boolean isSessionExpired(javax.servlet.http.HttpServletRequest request)

This method returns true if the session has expired.

Parameters:

Returns:

true if the session expired.

getValue

protected Object getValue(javax.servlet.http.HttpServletRequest request,
                          String key)

This method is used to retrieve any data that is used by the implementation of the servlet. The default implementation of this method depends on whether the servlet is in monosession or in multisession mode:

• If the servlet is in monosession mode, the attribute is fetched from a Hashtable member variable of the servlet.
• If the servlet is in multisession mode, the attribute is fetched from the request session using the call request.getSession().getValue(key).

If you want to implement another strategy to allocate views to sessions, you need to override this method and the IlvSDMServletSupport.setValue(javax.servlet.http.HttpServletRequest, java.lang.String, java.lang.Object) method. This method has been overridden to use JSF context.

Overrides:

getValue in class IlvSDMServletSupport

Parameters:

request - The current HTTP request.

key - The key.

Since:

JViews 8.0

setValue

protected void setValue(javax.servlet.http.HttpServletRequest request,
                        String key,
                        Object value)

This method is used to store any data that is used by the implementation of the servlet. The default implementation of this method depends on whether the servlet is in monosession or in multisession mode:

• If the servlet is in monosession mode, the attribute is stored in a Hashtable member variable of the servlet.
• If the servlet is in multisession mode, the attribute is stored in the request session using the call request.getSession().setValue(key, value).

If you want to implement another strategy to allocate views to sessions, you need to override this method and the IlvSDMServletSupport.getValue(javax.servlet.http.HttpServletRequest, java.lang.String) method. This method has been overridden to use JSF context.

Overrides:

setValue in class IlvSDMServletSupport

request - The current HTTP request.
