How to cache the Web Content Management API Workspace  

 When obtaining the Web Content Management API Workspace for the ‘System’ or users other than the current user, you should cache the ‘Workspace’ in the session to improve performance. Creating a workspace for a user is slow because Web Content Management needs to pre-calculate the user’s permissions. Caching the Workspace speeds up the rest of the API operations.

• • NOTE: This is a known issue when doing this with Web Content Management 6.0.0.0 and 6.0.0.1. For 6.0.0.0, apply PK35144 and PK36105 whereas for 6.0.0.1, apply PK35618

Example:

/ Returns the System Workspace */
Workspace getSystemWorkspace(HttpServletRequest request, HttpServletResponse response) throws IOException
{
String workspaceSessionKey = "System_" + Workspace.WCM_WORKSPACE_KEY;
Workspace theWorkspace = (Workspace)request.getSession().getAttribute(workspaceSessionKey);
if (theWorkspace == null)
{
theWorkspace wasn't in the session, create a new one and put it in the session
try
{
Get workspace for system user
theWorkspace = WCM_API.getRepository().getSystemWorkspace();

Store the workspace in the session to speed up next access
request.getSession().setAttribute(workspaceSessionKey, theWorkspace);
}
catch (ServiceNotAvailableException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
catch (OperationFailedException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
}
return theWorkspace;
}

 

/ Returns the Anonymous Workspace */
Workspace getAnonymousWorkspace(HttpServletRequest request, HttpServletResponse response) throws IOException
{
String workspaceSessionKey = "Anonymous_" + Workspace.WCM_WORKSPACE_KEY;
Workspace theWorkspace = (Workspace)request.getSession().getAttribute(workspaceSessionKey);
if (theWorkspace == null)
{
theWorkspace wasn't in the session, create a new one and put it in the session
try
{
Get workspace for Anonymous user
theWorkspace = WCM_API.getRepository().getAnonymousWorkspace();

Store the workspace in the session to speed up next access
request.getSession().setAttribute(workspaceSessionKey, theWorkspace);
}
catch (ServiceNotAvailableException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
catch (OperationFailedException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
}
return theWorkspace;
}

 

/ Returns the current workspace for the specified user */
Workspace getUsersWorkspace(HttpServletRequest request, HttpServletResponse response, Principal currentUser) throws IOException
{
String workspaceSessionKey = currentUser.getName() + Workspace.WCM_WORKSPACE_KEY;
Workspace theWorkspace = (Workspace)request.getSession().getAttribute(workspace SessionKey);
if (theWorkspace == null)
{
theWorkspace wasn't in the session, create a new one and put it in the session
try
{
Get workspace for current user
theWorkspace = WCM_API.getRepository().getWorkspace(currentUser);

Store the workspace in the session to speed up next access
request.getSession().setAttribute(workspaceSessionKey, theWorkspace);
}
catch (ServiceNotAvailableException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
catch (OperationFailedException e)
{
response.getWriter().println("Error creating workspace, " + e.toString());
}
}
return theWorkspace;
