Java Forum / General / December 2007Printing a HTML Document
Hi there, We have a little problem. We just started coding in Java and now we need to load a html document from a webserver and print it out. We figgured out this can be done using HTML component, but when we execute this code, the pages stay blank. My guess is that we aren't loading the page inside the HTML Component. Anyone got an idea??? Our code: HTMLDocument x = new HTMLDocument(); URL u; InputStream is = null; DataInputStream dis; u = new URL("http://www.mysite.com/htmlfile.php"); x.setBase(u); dr.print(x); >Hi there, > [quoted text clipped - 13 lines] >x.setBase(u); >dr.print(x); Can you print a very simple HTML document? <html> <head> <title>Hello World!</title> </head> <body> <p>Hello World!</p> </body> </html> from the local hard disc? HTMLDocument x = new HTMLDocument(); URL u; InputStream is = null; DataInputStream dis; u = new URL("file://localhost/C:/temp/helloworld.html"); x.setBase(u); dr.print(x); Once you get that working then add complications to the source of the HTML file and to the HTML file itself. rossum > We have a little problem.

In general HTMLDocument don't render by themselves. You have to lay them out somewhere. Remember HTML can be rendered in narrow or wide screens. Michael > What are "is" and "dis" good for?

So we have to render the code before sending it to the printer. Can you tell us how we render it? Michael Jung wrote: >> What are "is" and "dis" good for? What's a"dr"?

Now, to be fair, you should really answer Michael's questions, then ask your own.  SignatureLew >Michael Jung wrote: >>> What are "is" and "dis" good for? What's a"dr"?

I would say OTOH, that is is both sensible and constructive to answer the questions of people trying to help. >..you should really answer Michael's questions, then ask your own. One good way to answer most of those questions, would be to prepare an SSCCE* of the current code. * <http://www.physci.org/codes/sscce.html> SignatureAndrew Thompson http://www.physci.org/ Lew wrote: >> Now, to be fair, .. > Fair? I hate that word. To me it means 'light coloring'. That's like saying you don't use the word "good" as a moral judgment because it (also!) means "an item of commerce". Anyway, "fair" means "between the baselines", thus allowing the runner to attempt to reach first and be safe, while the fielders attempt to throw him out. If you want to test a ferris wheel, give it a fair trial. <http://en.wiktionary.org/wiki/fair> SignatureLew ... >If you want to test a ferris wheel, give it a fair trial. Yeah, yeah.. just allowing some of my 'petty (word) prejudices' show through. ;-) ( I prefer the roller-coaster, ..or dodgem' cars, BTW ;) SignatureAndrew Thompson http://www.physci.org/ > ... >> If you want to test a ferris wheel, give it a fair trial.

It looks like one term focuses on the defense, the other on the offense.) SignatureLew >> ... >>> If you want to test a ferris wheel, give it a fair trial.

Well actually ..now you mention it (wicked grin) my strategy was never the 'dodge' so much as the 'strategic bump'. ;-) SignatureAndrew Thompson http://www.physci.org/ > HTML Component. Anyone got an idea??? A platform dependent way would be use exec to feed the document to a browser with a print command. See http://mindprod.com/jgloss/exec.html SignatureRoedy Green Canadian Mind Products The Java Glossary http://mindprod.com Andrew, could you ask your question more specific? Then I will be able to answer it, and maybe you could help us out here. >Andrew, could you ask your question more specific? I felt Michael's questions were fairly specific, but ultimatety, "code* answers a thousand questions". * Specifically, code that is an SSCCE. >...Then I will be able >to answer it, and maybe you could help us out here. What did you *not* understand about Michael's questions? Note there is only so much 'guesswork' that people are prepared to do on your behalf - the rest needs to be filled in (stated/written/explained), specifically, by you. Have you *read* the SSCCE document yet? If there was anything in it that was incomprehensible (gobble-de-gook, nonsense, ..) I would like to be told that (since I created the document, and it is intended to help programmers). SignatureAndrew Thompson http://www.physci.org/ Got it fixed : import java.net.*; import java.io.*; import javax.swing.*; public class FileDownload { public static void main(String[] args){ JEditorPane output = new JEditorPane(); output.setContentType( "text/html" ); output.setEditable( false ); try{ output.setPage("mysite.com/file.php"); output.print(); }catch(Exception e){System.err.print(e);} } } >Got it fixed : Good work! Glad you got it sorted, and thanks for having the common sense to report it back to us. :-) ..But I wish I'd noticed this post before I 'got on my high horse', and wasted *that* bit of bandwidth! ;-) SignatureAndrew Thompson http://www.physci.org/ Free MagazinesGet these publications absolutely FREE for up to 12 months.
