RE: [platform-ua-dev] Assigning a static portnumber forhelpin external b

["Curtis D'Entremont" <curtispd@xxxxxxxxxx>]

Actually I meant in your own plugin.
If you can get your plugin to know when the user is going to have to restart
the workbench as part of a tutorial, you can get your plugin to write a
small file in the metadata in workspace. Whenever your plugin starts up
it looks if the file is there, and if it is, it means it needs to restart
the help server. You can start the help server by simply making a request.
For example, get it to call HelpSystem.getContent("/my.plugin/mydoc.html");
and this should trigger the server to start up.

Unfortunately though this will only
work if you're restarting in the same workspace.

I had a feeling it was something
like that. Thanks, Curtis.
 
I think option 1 may be best
for our case, but I honestly don’t know what that flag might be. Any suggestions?
I’m assuming you mean the help plugin.

Ah I know why.. it's because the help server hasn't started up again. It
only starts up when someone requests help (on demand). Unfortunately it
has no way of knowing your browser is trying to get help because in order
to know that it would need to have the app server started and listening
to the port. Unfortunately I do not see a simple way to accomplish this
at the moment. You can open an enhancement to request this if you like.
Here are some alternative approaches I can think of at the moment; some
of them may not be feasible for you but I'll mention them anyway.

1. Have your plugin set a flag that it has to poke the help system on startup
so that the help server will automatically start up again next time
2. Store the tutorial as static html files in the workspace metadata, like
PDE does for previewing schema documentation
3. Have your plugin manage a separate local infocenter to host the tutorial.
4. Store the tutorial content on a public infocenter.
5. Notify the user that they'll have to reopen help on startup to continue
the tutorial.

Looks like the connection’s getting refused. For the static port number,
I’m using one of the numbers given to me by Eclipse when it was setting
them dynamically. Is there a better choice?

Thanks, Curtis. The port number does indeed remain the same between IDE
instances. Unfortunately, after IDE restart links in the (still-open) help
browser are no-op. Neither topic links nor the TOC respond to clicking
– there’s a bit of hourglass, then nothing.
  
Am I missing something? 
Thanks, 
Steve

Hi Steve, 

You can use the port preference for the org.eclipse.help.appserver plugin:
http://help.eclipse.org/help31/topic/org.eclipse.platform.doc.isv/reference/misc/help_preferences.html

This preference is also exposed in the UI under the Help -> Help Server
preference page.

Subject	[platform-ua-dev] Assigning a static port number for help in        external browser

 

 

Hello – Is it possible to specify that the IDE should use the same port number for retrieving help? It appears that Eclipse changes the port number on IDE restart when an external browser is used.

I’m not using infocenter, where I see a port number can be specified. This is local help. The problem goes like this:

1 User is in the IDE, launches help (in an external browser) to work through a tutorial.
2 The tutorial requests that the user change workspace, or restart the IDE.
3 The browser instance remains open, but when the IDE has restarted, its links can no longer be reached. The user has to restart help and find the topic they were in to keep going.

Thanks,
Steve
