[jsword-devel] webstart

I seem to remember a tab at the bottom of the source window that would
flip you to gui mode.

 Since the project was already defined, I just opened the jpx file and
it did the rest. So I don't know about the ugliness.

 The reason I guessed that it was done in a gui builder was the jbInit
and the xxx_actionPerformed(ActionEvent e) methods.

 I still have not figured out how to open it in a GUI bldr.

Unless things have changed recently the annoying thing about JB
Personal is that it assumes that home users don't have many Java files
to edit, so you have to add each and every .java file to your project
individually! There was a shortcut where in the file add dialog you
could open the tree and add lots of files at the same time. You can
tell if JBuilder was used to edit GUI files because it generates
jbInit() methods. Joe. On Fri, 03 Sep 2004 15:05:16 -0400, DM Smith

Is this an appropriate version of JBuilder? So far I am poking around
trying to figure out how the IDE works and how the app is maintained
w/in it. (The code is easy to figure out.) Still wondering if you used
a GUI builder. If so, is it a part of Personal ver and how do you
invoke it? DM Smith wrote:
 I have dl svn from their website and have checked out the flashcard
files. I also tried subeclipse, but it did not work. It was missing a
required dll (libapr.dll, apache portable runtime). They know of the
problem and are working on fixing it. So, still no SVN from within
Eclipse. Troy, it looks like you have built the project w/ a gui
builder/ide. If so, which one did you use? DM Smith wrote:
 Troy, I had not looked at the program before. It is really useful! A
few months ago, I tried refreshing my Greek by reading along in
Nestle/Aland in church while scripture was being read in English.
Today, I had a go at the flash cards. I was amazed by how much I
remembered and by how much I forgot. Anyway, wrt your question: Can
you recommend a SVN client for WinXP or plugin for Eclipse. If so, I
will give it a go. Quick tutorial on webstart. (I.e. what I learned
the hard way) Webstart uses jnlp files, which is an XML descriptor of
an application and its resources. All resources need to be in jar
files and the program must be able to get them out of the jar. When
jars are listed, the one with the "main" needs to be listed first.
Webstart can display an icon and a splash that is not in a jar. This
is a niceity that makes the solution look more complete. Each jar
needs to be signed by the same authority using jarsigner. (I.e. use
the same keystore) The jars and the jnlp file need to be in the same
directory. If your application accesses the internet or the local
filesystem, it will need to be granted security permissions. The
simplest is to grant all. There is no way to pass command line
parameters (that I am aware of). But properties can be set. Mark has
recommendations for MacOS. Here is a sample jnlp file: <jnlp
spec="1.0+" codebase="http://www.crosswire.org/ftpmirror/pub/flashcards"
href="flashcards.jnlp"> <information> <title>Flash Cards</title>
<vendor>Crosswire Bible Society</vendor> <homepage
href="http://www.crosswire.org/flashcards/"/> <description>Flash
Cards</description> <description kind="short">Flash Cards is a Bible
study tool available over the internet</description> <description
kind="tooltip">Flash Cards</description> <icon href="icon.gif"/> <icon
kind="splash" href="splash.gif"/> <offline-allowed/> </information>
<security>  <all-permissions/>
</security> <resources> <j2se version="1.4+" max-heap-size="512m"/>
<jar href="Flash.jar"/> <jar href="FlashLessons.jar"/> </resources>
<application-desc main-class="flash.Quiz"/> </jnlp> The one for the
editor would be very similar. However, it would maintain a separate
installation of everything. The only way I see around this would be to
merge the two programs into one and make the editor a menu option. The
only change to FlashCards that I see is that the *.flash are not in a
jar. They would need to be put into a jar and served from there. The
code to get them out of the jar is pretty simple, you getResource(...)
using an absolute path relative to the start of the jar. So if the
lessons are in FlashLessons.jar in a directory named lessons, then
lesson 3 would be gotten with
getResource("/lessons/chapter03vocab.flash"). Alternatively, it can be
done as we have done in jsword. We have put ~/.jsword on the lookup
path for resources. The program will do lookups there first and
failing that then look in the jars. This allows for overrides and
extensions. The easiest way to get this "for free" is to include
common.jar from the jsword project and add these lines to your main
program: String path = System.getProperty("user.home") +
File.separator + DIR_PROJECT; home = new URL(NetUtil.PROTOCOL_FILE,
null, path); CWClassLoader.setHome(home); where dir project is
something like: private static final String DIR_PROJECT =
".flashcards"; So what would you like? Troy A. Griffitts wrote:
 Might anyone be willing to consider writing a webstart installer
thingy for our Flashcards application? We have some students in class
who have had trouble unzipping and finding the correct jar to double
click, and it would be a great blessing to many people, and me,
personally, if we had something to help this process. SVN checkout
with similar to: svn co https://crosswire.org/svn/flashcards/trunk
flashcards Thank you for considering, -Troy.
