Java Firefox Extension in Firefox 3?
by Bill Orcutt-2

Rate this Message:
Hi-
Has anyone attempted to use the Java Firefox Extension (or similar techniques for calling Java from chrome js) in a Firefox 3 beta? On the mac (OSX 10.5.2) my extension fails silently when when the first call to java is made. Was working fine in FF2. The XqUSEme extension- https://addons.mozilla.org/en-US/firefox/addon/5515 - which also uses java is similarly broken on FF3. Wondering if anyone at SIMILE has already investigated this issue... thanks -Bill _______________________________________________ General mailing list General@... http://simile.mit.edu/mailman/listinfo/general |

Bill,
I think we have seen a problem where if there is one exception thrown then the LiveConnect bridge just stops working altogether (until you restart Firefox). We got around that by catching all exceptions before they hit the LiveConnect bridge. That was a few months ago and it might have been with Firefox 2.0.0.1x rather than Firefox 3; and Ryan Lee was the last person to track it. I don't think we have really tried to keep up with Firefox 3. Please let us know if you make any progress on this front. Thanks!

Bill,
I seem to have gotten the Java Firefox Extension to work on Firefox 3: http://simile.mit.edu/repository/java-firefox-extension/java-firefox-extension-2.0.0.xpi Once it's installed and Firefox is restarted, the Error Console should say FooComponent.initialize { Greetings: Hello World! } FooComponent.initialize The string "Hello World!" comes from Java. Also you should be able to invoke Tools -> Java Firefox Extension: Do It! and get an alert of 43. You should also be able to open a new window, invoke that same menu command, and get 44. This shows that there is only one instance of the Test class shared across windows. The fix was to move the Java class instantiation code out of the XPCOM code back into the chrome code. The chrome code http://simile.mit.edu/repository/java-firefox-extension/firefox/chrome/content/scripts/browser-overlay.js has to do more work now, which makes it a little less pretty, but it works. On the other hand, we can do away entirely with all that policy setting hack! Frankly, I don't know why I didn't use this method before! :-) Let me know if you find any problem.

longwell semantic-bank: what's a profile?
by Jon Crump-2
::
Rate this Message:
Dear all,
I'm trying to get an instance of longwell semantic-bank running. I'm clearly missing some important step. I have no problem getting it running at localhost:8080 jjc% ./longwell -c tstbank [INFO] MAVEN_OPTS: ' -Djava.awt.headless=true -Dslf4j=true -Dlog4j.configuration=file:./src/main/webapp/WEB-INF/log4j.properties -Djava.security.auth.login.config=file:./src/main/resources/jaas.config -Dlongwell.configuration=tstbank -Djetty.port=8080 -Xms32M -Xmx256M' And I don't seem to have any problem logging into it using myopenid. All the expected data are there and I can browse it in the usual longwell way, but If I try to delete anything I get: 10:42:57.054 [..l.command.RemoveCommand] Unauthorized user attempted to remove from profile (120985ms) If I try publishing an item from my piggybank using the coin icon with the up arrow, I get this: 10:57:26.477 [..l.command.UploadCommand] java.lang.RuntimeException: Could not find profile with id: aHR0cDovL2pqY3J1bXAubXlvcGVuaWQuY29t (667669ms) (by the way, didn't piggy-bank items used to have a publish button along with the delete and tag buttons?) If I navigate to a web page in FF and execute the 'view this page in my banks' menu command in the piggy-bank menu, I get this: 10:59:12.215 [..ll.command.FocusCommand] java.lang.RuntimeException: Could not find profile with id: tstbank (9ms) java.lang.RuntimeException: Could not find profile with id: tstbank at edu.mit.simile.longwell.Longwell.getProfile(Longwell.java:165) at edu.mit.simile.longwell.Message.getProfile(Message.java:57) at edu.mit.simile.longwell.command.CommandBase.createContext(CommandBase.java:38) at edu.mit.simile.longwell.command.FocusCommand.execute(FocusCommand.java:22) at edu.mit.simile.longwell.LongwellServlet.doGet(LongwellServlet.java:576) at javax.servlet.http.HttpServlet.service(HttpServlet.java:715) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:362) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:722) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:404) at org.mortbay.jetty.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:206) at org.mortbay.jetty.handler.HandlerCollection.handle(HandlerCollection.java:114) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) at org.mortbay.jetty.Server.handle(Server.java:324) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:505) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:828) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:514) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:211) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.jetty.nio.BlockingChannelConnector$Connection.run(BlockingChannelConnector.java:163) at org.mortbay.thread.BoundedThreadPool$PoolThread.run(BoundedThreadPool.java:450) And logwell takes me to an empty page, while firebug reports: uncaught exception: Permission denied to call method XMLHttpRequest.open Clearly there is something about creating a profile that I'm missing. I'm not even sure what a 'profile' is in this context. The configuration.properties file for this instance has simply: # ---------- Extension --------------- longwell.configuration.extends=semantic-bank # ----------- Templates ---------------- longwell.template.header=components/sourcenotes-header.vt Perhaps there is something else I need to do here? My intention is to do some testing to see if the semantic bank might be the right tool for the application I have in mind. I need also to find out if it is possible to add and subtract items from the semantic-bank programmatically from some context other than piggy-bank. Is it possible, for example, to upload existing rdf data to the semantic-bank via curl or from a php page? Any clues?

It's been some time since we worked on either Piggy Bank or Longwell.
Considering upcoming transitions, I don't know how much we can put into support for either. This may be a case of logging an issue and coming back to it in due time.

The publish button was removed for the upload coin, since OpenID login needed to go through the browser and couldn't be initiated in an integrated way from inside a web page. > And logwell takes me to an empty page, while firebug reports: uncaught > exception: Permission denied to call method XMLHttpRequest.open > > Clearly there is something about creating a profile that I'm missing.

It is not presently possible to do so unless you can automate your OpenID credentials. -- Ryan Lee ryanlee@...
