JavaHelp with Wicket

Is it possible to add JavaHelp to web application ?I couldn't find realization of JavaHelp on web application . I*m writing on Wicket.

Hi,
I am facing exactly the same issue. Did you get some solution for this?
Since JTree is a component and DefaultMutableTreeNodes inside it are not (extend directly from java.lang.Object), we can attach CSH only to the overall tree and not to the separate nodes is it?
I have to solve this As Soon As Possible. Somebody please reply soon.
Thanks.

CQ5.5 Integration with Wicket

What is the best possible approach to integrate CQ5 with Wicket?
1) Do we need to Use a OSGI based Wicket Framework like PAX-Wicket ?
2) What are the integration choice avaialbe in CQ5.5 for integrating Web Application like Wicket ?
Can someone share their experience ?
Thanks,
Tejas

As you can use multiple modules within single repository. Ex:- The module settings at [1] This module tries to authenticate a user based on the users stored in CRX. If user is not authenticated it uses next module LDAPLoginModule. If all module could not authenticate then request fails. More details go through below links.

Best way to bundle JavaHelp with application

What is the best way to bundle JavaHelp with an application....
At present I have to run the application that uses JavaHelp as follows
java -classpath ;lib/jhall.jar HelpMenu
Is there a better way? so that when the application is moved to a client machine the classpath to the javaHelp jhall.jar does not have to be supplied as above?
Cheers :)

If you don't want to specify the classpath you can
1> either create a batch/shell script with lauches the app with the appropriate classpath
2> You jar your app and specify the classpath in your jars's MANIFEST.MF file like this.
Main-Class: main class name which will launch the app
Class-Path: jhall.jar
The above entries assume jhall.jar is in the same dir as your main jar. You can put more jars in the classpath above by separating them with space.
With this the app can be just lauched by typing: java -jar filaname.jar

JavaHelp with JBuilder

Hi,
We are using the JavaHelp API in Jbuilder Open Tools. Our help is going to be on the main menu bar of JBuilder. We've used CSH.DisplayHelpFromSource but it doesn't work. We cannot use menuItem.addActionListener(hb) since we are not dealing with menu items but with BrowserActions.
When we run our open tool there is no error but no help is displayed either.
Please somebody help us.

I think the first thing you sould to check whether the file URL is avilable, otherwise he cannot resolve.

Distributing javahelp with an app

Hi
I have an application which uses JavaHelp and this works great on my development workstation. I wanted to distribute my app at this point and wondered if anyone could tell me what i'm missing to get the JavaHelp system working on another machine. I haven't packaged anything separately, it is all within one jar file (helpset.hs, map.jhm, toc.xml etc). When I try to run my app on any other machine so far, i get the error message:
"java.lang.NoClassDefFoundError: javax/help/HelpBroker."
What do I need to package with my app so that the target machine can run my app and the javahelp system? Do I need to package the jh.jar along with it?
Please help.
Thanks!

never mind I solved it.

Deploying JavaHelp with Webstart

I am trying to deploy my app using Webstart and I cannot get the content HTML topics to load.
I have 3 JNLP's (due to the JAR signing issue), the first is for my app's JARS, the 2nd is for the JavaHelp JAR, the 3rd is for my HelpSet JAR(which contains everything for JavaHelp). The 2nd JNLP is referenced by the first using the "extension" resource spec. Same deal from the 2nd to the 3rd.
The HelpViewer comes up and everything is there EXCEPT the topics. Very strange. I tried all manner of URL specs (from simple to full) in the MAP file but nothing works. Seems JavaHelp will not work with Webstart.
Any ideas?

I figured out the problem.
1. You actually don't need the 3rd JNLP file since you do not need to sign 3rd party JARs already signed.
2. Don't sign JARs that are already signed, just put them in the 2nd JNLP.
3. ANT builds must be carefully written to mimic precisely what your IDE is doing.
a. But, Eclipse does not copy HTML files to output directories no matter what, ignores inclusion filters.
b. Manual JAR tools will archive whatever you tell them to.
4. You must sign any 3rd party JARs that are not already signed or webstart will not allow your app to run.
5. Any missing JARs in your JNLP(s) will cause webstart to throw exceptions but leave your app running in the background, potentially preventing any new instance from running, so you must kill it. This masks your fixes.
6. Webstart and JavaHelp documentation needs a lot of work.
I could go on and on.

JavaHelp with JTree

I have just started using JavaHelp today, and I've figured out the general opening of the help window with F1 and the help broker, and also triggering context-sensitive help.... However, I can't seem to figure the correct way that I could register context-sensitive help for tree nodes. I have a tree that will have a specific set of named nodes, and there will be help topics for each type of node, so I'd like to have help linkable to the type of node. Can anyone point me in the right direction? Thanks,

Launching JavaHelp with a modal dialog

Hi,
I am trying to launch JavaHelp from a modal dialog, which consists of a JTabbedPane with 2 tabs. My code right now checks to see which index is selected, then sets the help ID accordingly. However, when I run my application, JavaHelp simply does not launch. How do I work around the problem with the modal dialog...the code for checking the index is correct, because it works in another part of the application, only that window is not modal.

hi there
you can try with       helpButton = new JButton("Help");
      CSH.setHelpIDString(helpButton, helpTopicId);
      if(myHelpBroker != null) {
        helpButton.addActionListener(
            new CSH.DisplayHelpFromSource(myHelpBroker);
      } supposed you initialize myHelpBroker with something meaningful (a valid help broker pointing to the help set in question) and helpTopicId with the id of the topic to be displayed

JavaHelp with JavaWebStart: grey frame

Hello all,
I have my help in HTML pages on a Web server. The client is using JavaHelp to display these HTML pages.
It works fine, if I run my client through an IDE (like JBuilder). However, it does not work, if I run using JavaWebStart. I get a grey window frame (no TOC, no HTML pages displayed).
The code I am using to get an instance to JavaHelp is the following:
URL hsURL = new URL("http://myserver/myHelpSet.hs");
_hs = new HelpSet(null, hsURL);
hb = mhs.createHelpBroker();
Then later,
jMenuHelp.addActionListener(new CSH.DisplayHelpFromSource(_hb));
This seems to work fine. I do not get any exception. The helpset seems to be correctly located.
Any idea would be very welcome. Thank you. Marc.

I am using webstart as well, but I am delivering my help files in a jar file that gets downloaded to the client. The helpset file seems to be getting loaded fine, but I am getting a security error when trying to launch help from the application. This all works outside of Webstart delivery. Here is the error message:
"Parsing failed for null
Exception caught while parsing nulljava.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)
java.lang.NullPointerException
     at javax.help.plaf.basic.BasicFavoritesNavigatorUI.reloadData(BasicFavoritesNavigatorUI.java:290)
     at javax.help.plaf.basic.BasicFavoritesNavigatorUI.installUI(BasicFavoritesNavigatorUI.java:228)
     at javax.swing.JComponent.setUI(Unknown Source)
     at ..."
Obviously a security issue, but since all of the help files are in a jar file, shouldn't this be legal? Maybe JavaHelp is just trying to read the files normally I guess.

Security Exception with JavaHelp and Webstart

I have seen several posts on here concerning JavaHelp with Webstart, but no one seems to be getting the same error that I have. Everything works fine if I run the application and launch help outside of Webstart.
When I download the app using webstart, my helpset seems to get loaded properly, but I get the following error when trying to launch JavaHelp from within the application:
Parsing failed for null
Exception caught while parsing nulljava.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)
java.lang.NullPointerException
I'm not quite sure why it's trying to access the property user.home, but it doesn't seem that others that have post get this error.
Does anyone have any suggestions?
Thanks.

Ok... this appears to be an issue with the new JavaHelp 2.0 because it works perfectly fine in version 1.3
It appears that version 2.0 has a "favorites" section that, I'm guessing here, stores the users favorites locally. That would be why the user.home property gets accessed and the security policy is violated with Webstart.
I can't say that this is a bug... maybe I can disable the "favorites" feature... either that or I need to stick with JavaHelp 1.3
Thanks.

RoboHelp 10 fails to build JavaHelp Search

When I generate JavaHelp with RoboHelp 10 I have the error below in the console:
java.io.FileNotFoundException: myProject_JavaHelpSearch\POSITIONS (...)

    at java.io.FileInputStream.<init>(Unknown Source)

In the working directoty used for JavaHelp, the "myProject_JavaHelpSearch" sub-directory contains:
DOCS
OFFSETS
TMAP
The error is not fatal and RoboHelp do generate the JavaHelp file. The JavaHelps displays TOC, Index, and the project pages as expected, but when I try using the "Search" tab in the generated JavaHelp, it does not work.
If I generate a Microsoft HTML Help or WebHelp, the "Search" tab works fine.
My project is a former RoboHelp 9.1 project converted to RoboHelp 10. It was working fine on Windows XP Pro Us (32 bits) + RH 9.1, I'm running now RH 10 on Windows 8 Pro French 64 bits.
Thanks in advance for any help.

There is nothing there about Rh10 and it is not a topic I will be updating. Sorry but JavaHelp is not a popular output. Flare does not even offer it for reasons stated in the page on my site.

Javahelp display issues (RH2002 to RH9 upgrade)

Hi,
First of all, this forum has been a godsend as instalation was a nightmare. Thank you.
Here's my latest issue...
Compiled javahelp looks fine in the local viewer, but not after delivery (when opened through my product's Help menu). It doesn't honor the style sheet. (I'm using my own, not RHStyleMapping).
My Arial fonts display as Times New Roman, "<<" marks display at line breaks, some of my headings are teeny tiny (yep, that's the technical term ), etc.
Steps to recreate:
First time use in RH9: opened project by d-clicking the .mpj file (RH2002) and letting RH9 run through the upgrade process.
In Project Settings dialog, I selected javahelp as my primary output and my customized style sheet as CSS for Style Mapping.
Generated compressed javahelp with source files using JH 2.0
Confirmed .css file is in compressed jar.
I upgraded my java tools when I upgraded Robohelp
(to jh2.0 and jdk 1.5.0_06)
Any suggestions?

What is the make and model of your video card?
What is the number and date of the installed video driver?
Is that the latest release from nVidia, or AMD/ATI?
If it is not the latest, go to the nVidia, or AMD/ATI Web site, plug in your card, and your OS, then download and install the latest driver. Test.
Do not trust Windows, or any utility to tell you if you have the latest driver. Verify that from the mfgr's. Web site.
Good luck,

Including javahelp in a jar executable

Hi, ive just created an application and would like to include a javahelp with it, ive got it running off my local machine with the java helpset working too , but what im wondering is, is it possbile to include jhall.jar in the application jar so people who do not have javahelp installed can still view the helpsets ? and if so how do i point to it so that it imports it when the helpset is called upon.
here is my manifest file
Manifest-Version: 1.0
Class-Path: ./jhall.jar

Try this; - where 'help' is a dir in your jar.
     try
               URL hsURL = getClass().getResource( "help/myhelpset.hs" );
               hs = new HelpSet(null, hsURL);
               // found helpset, allow help
               HelpBroker hb = hs.createHelpBroker();
                         menuItemHelp.addActionListener(new CSH.DisplayHelpFromSource(hb));
               // add help functionality to main menu
               menuHelp.add(menuHelpHelp);
               menuHelp.addSeparator();
               menuHelp.add(menuHelpAbout);
               menuBar1.add(menuHelp);
               // add help functionality to toolbar
               toolBarImages.addSeparator();
               toolBarImages.add(buttonHelp);
          catch (Exception ee)
               JOptionPane.showMessageDialog( null, "Be aware that online help could not be loaded.");
               //System.out.println("HelpSet " + hs.getTitle() + " not found");
               // helpfile not found. disallow help

JavaHelp and JavaWebStart

I am developing a JavaWebStart application. I would like to use Javahelp with it.
Is this possible?
Has anyone done this?
Would each user have to install JavaHelp on their workstation?
I know I can download the JavaHelp jar files via jnlp, but how would I set the JHHOME variable?
Thanks,
Jim

I didn't try the demo apps, I went and added JavaHelp to my application. This part was the same as the demo apps. I then added the following to my .jnlp file under resources:
<extension name="JHelp" href="jnlp/jhelp.jnlp"/>
I then created the jhelp.jnlp file as follows:
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://localhost/ccs" href="jnlp/jhelp.jnlp">
     <information>
          <title>JavaHelp</title>
          <vendor>Sun Microsystems, Inc.</vendor>
     </information>
     <resources>
          <jar href="lib/jh.jar"/>
     </resources>
     <component-desc/>
</jnlp>
That was all that's to it.
