Is there some sort of library that I can use to embed a browser into a JPanel so that I can watch a stream from twitch.tv or ustream.tv??
I've looked around and found http://www.developer.com/java/ent/article.php/3644196/Eclipse-Tip-Create-Rich-User-Interfaces-with-the-HTML-Browser-Widget.htm
but it looks like it's only HTML compatible.
Depends what you want to see and how it is streamed:
You wants to see the web page twitch.tv:
You can use the SWT Browser widget, a 3rd party Swing HTMLPanel or going with JavaFX2.
You wants to see only the stream:
If the stream is Flash I think there is nothing to do. If it is HTML5 you can go with JavaFX2.

I am trying to make a web browser that works entirely on voice commands (i.e speech-to-text and vice versa using sphinx.)
I have a Java applet, but I don't know how to add a parser to it so that different parts of different websites go to a particular segment in my browser.
What are the necessary steps to add a parser to a web browser applet?
You don't need java applet, it creates too many issues. You need something like pocketsphinx.js:
https://github.com/syl22-00/pocketsphinx.js
This technology can give you access to content of the browser with javascript, a way easier way to manage things.
Now i am able to make a fully speech based web browser. I used Jsoup for extracting various elements of any web page. Then with the help of sphinx and freetts i allowed users to interact with browser by using speech commands only.
I have just started working with GWT. I was wondering how I can dynamically move widgets on fly (at web page on client browser) for example to move a row of table up and down, or upload a excel file and display its content right away....something like a dashboard I am talking about. Are there any comprehensive tutorial to refer.
Have a look at the gwt-dnd lib:
http://code.google.com/p/gwt-dnd/
GWT is made for doing the kind of things you are describing. To move widgets you can either set their position or dynamically modify their css. To move rows around in a table look at the api of whatever table class you are using. To upload an excel file do a google search for 'gwt upload' and there will be some instructions - but to display the file you will need to convert it (probably to xml). Converting the file on the server will depend on which server you are using - I also have seen a 3rd party widget that will do that for you.
If youre looking for transition effects or animations , than check out gwtquery. Its really similar to jquery and has pretty simple good examples to start with.
i've been searching on the internet on how to convert a HTML page into a PDF file using Java. i found a lot of pointers, and in short, they don't work or are too difficult to implement. i also downloaded a commercial product, pdf4ml; the API is something i'd be happy to work with, except that when i crawled a simple page on wikipedia, i get a out of memory error (setting Xmx to 1024 M). in some approaches, they suggest converting HTML -> XHTML -> FO -> PDF. however, i am getting a lot of exceptions for the XHTML-to-FO XLS file; and reading the documentations, it's not something that i have enough time to understand right now.
here are my questions/concerns.
1. is there another cohesive API out there that will easily convert HTML to PDF (commercial or not)?
2. is there a way i can simply capture a HTML page and store it as a single file. this approach would be similar to using internet explorer's way of saving a web page as a web archive (single file, MHT format)?
any help is appreciated. (btw, i know this question has been asked repeatedly, but in addition to the original spirit of the question, i'm opened to other ways). thanks.
Try wkhtmltopdf, which is using WebKit. Another option (I'm using that currently) is using OpenOffice (remote controlled via macros).
you may use iText open source Java lib for that, and read this
or use YaHPConverter open source Java lib.
or do this whith help of icepdf popular open source lib
or use pd4ml, but it not free, only trial.
or use this, and this is man for it.
My 2 cents using opensource tools:
You can use either Capture screenshots with Selenium or WebDriver to save html page's screenshot in an image file from your Java code. And once you have image file you can convert it to pdf again from your Java code.
EDIT:
It seems you can do all that in 1 step using itext Html to Pdf
I am not sure but you could Try
1) cobra html rendering engine http://lobobrowser.org/cobra.jsp
2) htmleditorkit -- part of jdk
3) JWebPane
Use the rendering kit to parse and render html. The rendered out put is a swing component. Swing component can be used by itext to generate pdf file out put
You can try out Pdfcrowd. It is an easy to use commercial online API with many options and with support for Java.
It can create PDF either from web pages or raw HTML code.
I am working on an application which needs to preview privileged content in the browser. The preview should work in a way that its NOT possible to download the content. Only reading within the browser is allowed. I have looked at google docs preview but it needs the url of the docs to accessible online. I need to work with content in the intranet
The previewer should not mandate the installation of a pluggin as this would limit the access.
Any hints
Have a look at ImageMagick. If your're using, say, php, you could do something like
exec("convert -resize 500×800 {$file}.pdf {$file}.jpg");
and then display the resulting jpg-file on a webpage.
man convert should give you some further options.
I have a small (500kb) swing applet that displays very simple/limited set of small HTML page(s) inside it with JEditorPane, however this does not seem to work 100% fluently, some customers get a blank page displayed without any java exceptions. The page works OK from my machine. I need a more reliable way to show HTML page to all our users.
Any ideas if there is a small + free class to use instead of JEditorPane
OR is there an easy fix to make it more reliable (non blank)
private JEditorPane m_editorPane = new JTextPane();
m_editorPane.setEditable( false);
m_editorPane.setBackground(new Color(239 ,255, 215));
m_editorPane.setBounds(30,42,520,478 );
m_editorPane.setDoubleBuffered(true);
m_editorPane.setBorder(null);
m_editorPane.registerEditorKitForContentType("text/html", "com.xxxxx.SynchronousHTMLEditorKit");
m_editorPane.setPage(ResourceLoader.getURLforDataFile(param.trim()));
Although I haven't used it before, Lobo is an open source web browser for Java with support for HTML 4, Javascript and CSS 2.
Compared to the JEditorPane which only has support of HTML 3.2, it seems like Lobo may be a better bet for loading modern web pages.
AFAIK, JEditorPane is a very primitive HTML component: it is confused by CSS and knows nothing about JS.
I doubt you will find a "small + free" class doing better, HTML parsing and displaying isn't a simple business, even less today.
Perhaps it is better to let the big names in the business to take care of this task, ie. using Internet Explorer or Mozilla components (depending on what is available, etc.): JDIC: Embedding a Web browser in Java.
I've recently POC-ed several java HTML rendering solutions. We decided on JEditorPane because we really need to minimize the size of our jar and it's built into Swing. However, the best library I came across was Flying Saucer. It doesn't have any js support but it's rendering quality and api is top notch, and it's "free" (LGLP), 100% Java, and only about 1mb (still too big for us, but small compared to other options). However, it only renders strict XHTML (all attribute values have to be quoted, all tags properly formed), but that may be OK depending on your needs (and HtmlCleaner or some other such utility may help towards that end).
