Lets be careful here, with the IPR, I assume Ian will declare some sort of IPR that would be compatable with EPL.

Also I assume we will just take the what has done for IE and FF relative to HSS and adopt that approach

Yes, I'd like to take a look at it.  If you can point me at some source code, I'll try to get the client-based selector to launch.

Actually, I just finished a "selector connector" for safari yesterday.  It is very rough around the edges, but it launches the AIR selector on xmldap.org, so that's a start.  Would you like to take a look at it Andy?  I suppose I can put it up on the Wiki somewhere...

Very cool. If we add support for Axel's selector (OpenInfoCard) and CardSpace, we will have coverage for all of the major selectors. Thanks for your work on this Jeesmon. BTW, I plan on starting work on a Safari add-on soon. Is anyone else working on supporting Safari? If so, we should collaborate.

Hi Mike/Tie Li,

I checked in a Firefox extension that can launch external selectors directly or using Higgins Selector Selector. It is based on Novellâs firefox addon for client based selector and it has the support to directly launch Higgins selectors (Client Based Selector, RCP Selector and AIR Selector). You can find more information on this extension athttp://wiki.eclipse.org/Higgins_Browser_Extension_for_Firefox and installation steps at

http://wiki.eclipse.org/Higgins_Browser_Extension_for_Firefox_Installation

I use nsISocketTransportService (http://developer.mozilla.org/en/docs/Proxies_in_Necko#SOCKS_and_nsISocketTransportService) to connect to RCP Selector from the browser. But I couldn't find a way to inform the socket server that there is no more data to send like you did in IE by calling shutdown with how = SD_SEND. So the while(true) loop in RCP Selector waits forever. I tried flushing and closing outputstream but socket server is not recognizing it as EOF. I cannot close the connection as the browser needs to wait for the token from RCP Selector. Until we figure out a solution (not sure whether we will), would it be possible for RCP Selector to break the while(true) loop if the input is terminated with the null char (\0)? I remember seeing \0 as the input terminator char in other socket implementations. Since \0 is not a legal char for the XML input that RCP Selector is getting, I don't think it will break anything else.

In line # 80 of org.eclipse.higgins.crpps/src/org/eclipse/higgins/crpps/service/RPPSService2.java (parseInput method)

change

while (true) {
int ch = in.read();
if (ch == -1)
break; // end-of-stream, assumes that sender closes sock @ end
// of message. which is not a must in HTTP....
.....
}

to

while (true) {
int ch = in.read();
if (ch == -1 || ch == '\0') // <------ break on null char also
break; // end-of-stream, assumes that sender closes sock @ end
// of message. which is not a must in HTTP....
.....
}

I tested RCP Selector with this change and I was able to successfully use it from FF. Please let me know if this change can be committed so that we can use RCP selector for more platforms and browsers. I assume there is no FF extension is created for RCP Selector so far.

Thanks a lot for your input on this.

Regards,
Jeesmon
