Questions about capabilities

I am a relatively inexperienced, intermediate Java programmer. Before I devote more time to learning Java I need to know if it is possible to do a few things that I need to do. These things are directly connected to Firefox so I am posting the question here. I appreciate any help anyone can give me. I need to build a desktop application that can display HTML based content. It needs to be able to display the same kinds of content that can be displayed in the user's Firefox browser. In other words, if the user's Firefox installation can display Flash then my app needs to be ab

how to accessing java ?

Hi all , I currently have some Java classes. Instead of converting them to Javascript, I am exploring of using Java XPCOM or Liveconnect to connect js and java into a firefox extension. However, I find some news about Liveconnect is not longer going with firefox 3.6 , is it true ? And anyone knows what's the difference about javaxpcom and liveconnect ? if you have any suggestion about develop java in firefox extension , please let me know! Any help will be appreciated, Thanks, Andrew

FW: calling Java code from Firefox extension

Hi all, Well, as I said, I want/need to have the firefox extension communicating with another java application. From what I've read so far it seems that the best approach is to have a XPCOM. That seems exactly like what I need! the problem is that the page (https://developer.mozilla.org/En/JavaXPCOM ) was last updated in 2006 and the examples in 2007 (or something like that), not only it's old but also very poorly documented and explained. Since the JavaXPCOM is so poorly documented, (1 ) what I need now is some examples that will help me develop a working skeleton on which I will

How can I dump log messages from Java code in Firefox extension?

Hi, I can call a Java code I wrote from a Firefox extension written in JavaScrpit, using the workaround described at: https://developer.mozilla.org/en/Java_in_Firefox_Extensions But when I try to dump some debug messages by using Logger or System.out, nothing appears in the console of Firefox. What is a good way of recording log messages in JavaCode that is called from a Firefox extension? Just to be clear, what I mean by the console is the command-line window that shows up when you invoke firefox.exe with the "-console" option. I changed the value of "browser.dom.window.dump.

Memory leaks when embedding and using JavaXPCOM

Hi all, We=92ve made a simple XULRunner app, coded in Java. We=92ve observed that it has huge memory leaks. Rewriting the same app in Javascript, we observe no leaks. So, we suspect there is some problem with JavaXPCOM. Maybe the problem is related with the cycle collector. https://developer.mozilla.org/En/Interfacing_with_the_XPCOM_cycle_collector It only traverses objects that return a helper object when QI'ed to nsICycleCollectionParticipant. If it encounters an unknown edge during its traversal, it gives up on that edge; this means that every edge involved in a cycle must

Disable Link-Navigation in mozSwing

Hi folks I have a special use case for mozSwing: I have to disable the link navigation, so that when the user clicks on a link nothing happens. The user should view a single page which he can=92t change by clicking on a link. I tried the following: I attached a nsIWebProgressListener and in onLocationChange I canceled the request: request.cancel(IXPCOMError.NS_ERROR_ABORT); The problem is that the page already changes its location but can=92t be loaded completely because I disabled the request.

String parameter in nsIOutputStream.write(...)

Hello, I have a few interrelated questions about the write() method of the interface org.mozilla.interfaces.nsIOutputStream that takes two arguments; aBuf of type String and aCount of type long. 1) The C++ counterpart of the method takes a char array. Exactly what is being done to convert a Java String to a C++ char*? 2) What should the value of aCount be? Should it be aBuf.length() or aBuf.getBytes().length or some other value? 3) What if I want to write binary data? Is this interface suitable for that task at all? Thank you. -Seong

Using JavaXPCOM and XulRunner under linux

Hi everybody, I've seen somepost about embedding xulrunner with JavaXPCOM and I wonder if you can help me. I've managed to create an embedded browser in swing using javaxpcom and xulrunner-1.8.0.4 on windows. I use a canvas to embed the browser, getting the handle of the canvas natively from the SO.

XULRunner mozcrt19.dll error

I have been using XULRunner 1.8 and 1.9 betas via javaxpcom in my Eclipse application. It had been running ok until I tried to upgrade to the latest release recently. I tried version 1.9.0.5 and got following error when it tried to initialize XPCOM: "This program could not start because MOZCRT19.dll could not be found. This problam may be solved by reinstalling the program." I back tracked various releases and found that this problem started at RC3. RC2 was ok. The difference between RC2 and RC3 that I believe is related to the problem: "Microsoft.VC80.CRT.manifest" vs. mozcrt19.d

Sample code - JavaXPCom

I have a Java app that works as an HTTP proxy which I'm trying to integrate with Gecko through the JavaXPCom to utilize its DOM rendering abilities to enable server-side DOM rendering/creation/ serialization for scrape purposes.

However, I currently have no way of simulating running/opening/rendering that page server- side so that javas

XULRunner for Swing Browser Support

Hi, I download mozswing and xulrunner and successfully have integrated the mozswing browser into my Java application. My problem is that with the required xulrunner distribution now needing to be packaged with the application my installer executable size has gone up by about 13MB! (the size of the /xulrunner directory). My question is that probably I do not need many of the files in this build (all I do is use the browser to show simple web page content, nothing else) so is there an available smaller build? If not, what files might I be able to remove? Thanks, Neil

nsIPrintSettings.setPrinterName has no effect in CUPS/Linux when printing silently

Hi, Was someone lucky to get silent printing in Linux / CUPS for non- default printer? Suppressing print dialog with settings.setPrintSilent(true) causes Gecko to print to default CUPS printer ignoring printerName property. When silent print is off and you select required printer in dialog all works fine. It seems like print dialog implementation kicks CUPS to use specified printer. Windows works fine... Gecko is 1.9 Thanks

working with liveconnect

Hello, I'm working on a firefox extension that needs to use java classes and requires communication both ways between java and ff. So liveconnect seems to be the way to go from what I'm reading. However I'm trying to write just a very basic javascript file that declares a java string (like in the tutorials) and it doesn't appear to be running properly. I'm pretty sure it is firefox and not my javascript because I've run a number of liveconnect tests I've found online and am getting inconsistent results. For example I attempted the test found here: http://srp.stanford.edu/demo/

GFX impl on top of Swing

I was reading the following in the embedding FAQ: --- What widget toolkit does Mozilla use? Mozilla makes its own cross-platform widgets for HTML forms, and does not use a 3rd-party cross platform toolkit, nor the native widgets that a platform provides. The widgets are drawn using GFX, Mozilla's abstraction of a drawing toolkit. They are styled with CSS, including minor per-platform tweaks to allow them to look like the native platform's native widgets. This allows full CSS and DOM support of all HTML widgets across all platforms, without requiring each platform to separately s
