How to make Help view well on both laptops and desktops

Hi -- I'm trying to learn RoboHelp 7 and just created my first WebHelp project. I want to show it to a friend, but don't have a server I can publish it to, so I copied all the files onto my flash drive and put it on my laptop. It all works fine, which is a relief -- however, the custom colors are way off, and some of the screenshots are now too big, so the user would have to scroll (which can be annoying). I created it on my desktop and have been looking at it on a larger monitor (1680x1050), but the laptop is old (1024x768). The thing is, a lot of people might have to view it on 800x600.
I couldn't find any information in RH's Help about how I should have set it up so that it views well on different systems. I'm hoping someone could please advise me as to what I should have done, and if there's anything I can do now to fix it, or point me to some information. I used Arial 10 pt for the text, and now it looks 12 pt. Should I have made it 8 pt? Is there a rule for how large an image should be to be viewed on a laptop and a desktop?
One last thing, it's too large to put on a CD, so is does anyone know how to make this into an executable?
Thanks in advance for any help you can give!
Daryl

Hi Daryl
I use an eBook compiler to convert WebHelp to an executable file. You might investigate eBook compilers for that bit. However, I'm not sure how that would help you since a compiler will do little more than to take a swarm of WebHelp files and store them in a wrapper to create a single file. Generally you will end up with something that although it exists as a single file, is larger than what is inside.
Are you SURE it's too big for CD? CD will hold 650 megs (700 if you buy the extended types).
On the screen size issue WebHelp itself should adapt fine. Probably it's the images you are concerned with. And the general rule of thumb is to capture images at a reasonable size to begin with. Never EVER just insert a big ole image into RoboHelp and grab the sizing handle to make it smaller. It will still consume a larger amount of space and the quality will suffer badly. So the best approach is to copy the image at a reasonable size to begin with. Something that may fit nicely in the Topic Pane area as it is presented in the space provided by the lowest common denominator. In your case I believe you said that many are still at 800x600.
Your 10 point text will still be 10 points at a smaller resolution. It will just look a bit different.
Hopefully this helps... Rick

How to make an standalone java application that uses mysql driver

Hi,
I have an application that makes connection to a mysql database, on my computer, I set on classpath the driver address, so everithing works fine.
The problem is that I want to execute my application from other computers, where the classpath does not have the drivers.
So my question is how can I package the driver? so, everybody can run my application from a Jar, for example.
thanks in advance,
- Susana

Nobody answered me, but I post the solution I found, that maybe can help somebody else with this problem:
I packed all my application sources (.class) and the drivers sources (.jar) with the tool: FAT JAR. It is an Eclipse plug-in. And now I can run mi application from the resulting Jar in other machines without installing the conector.
Bye,

How to make changes to Java for Lion

Forgive me, I am not experienced with Java Applets or the website I am mentioning in this post. I am asking for another person and have only been able to run tests and theories this evening.
It seems that the most recent Java upgrade has caused some issues with runescape.com Several Mac users at the site are reporting the same issue. When attempting to log into runescape an applet requests permission to access the computer. Actually, the warning window pops open and closed so quickly I have not been able to capture the text in it. Next, a Java Applet opens in the Dock and another warning/certificate window opens where the user can choose to Deny or Accept the certificte. Prior to the update the applet was handled within Safari. Apparently there were no additional steps to logging in. I recognize that Lion does not provide a Java runtime by default so I am wondering if changing that setting would enable runtime to do its thing without having to go through several approvals. The Java Applet runs anywhere from 28% to 100% (and sometimes more—I don't undestand that) of the CPU.
Alas, this is still not the main issue at play. Apparently the applet causes the application/website to respond v-e-r-y s-l-o-w-l-y Is there a way to achieve the same speeds that were available prior to the update? Ideas that I have been floating have been to downgrade from the present Lion/Java combination to Snow Leopard and the penultimate version of Java (next question: where can update 5 be downloaded). I have tried to install previous versions of Java but none are available for the Lion OS. Another option is to deny the applet and the user is taken to an alternate login page. The page loads the applet in Safari but there are severe limitations to the game (reported to me—I have no basis to compare). So what the user gets in speed is limited by the fact that they can only play in "one world".
In summary, my questions are this:
Does someone have a workaround for the Java Applet slowdown for this game, Runescape?
Is there a downgrade option available for Java in Lion? (my searching has not found one)
Is there a way to change the default runtime setting? (I have read at least one post where the user tried to edit settings in Java Preferences and they did not stick but they might not have restarted their browser)

Hi,
ITS i dont have an idea but from portal we can do CTRL+RIGHT CLICK AND WE CAN HIDE THE FIELD.
Try the same in ITS in the iview out put.
Thre are some tables where we can hide some fields for old ESS/MSS packages.
Try that.
If we are using portal we can go for NWDI ALSO.
Thanks,

How to make table in java?

I 'm trying to add some GUI interface, and now i need to insert three table into my JFrame, I'm not sure how to do it, should I create a JPanel first, and add the JTable into it, or just do it directly.
the second question is still about changing the frame, it something like event handling, how to change two windows on the screen when I click a button, I mean, the current wondows should close, and a new one can come out, I know dispose(), and hide()method already, but these two method can't clear the previous windows completely, so the new one come out, but the previous one still there, so, any good way to do it?
Thank you for your excellent suggestion!

Hi
It depends what you are doing! You can add Panel or any container.
e.g.
JTable table = new JTable (4,4);
Container c = getContentPane();
c.add( table, BorderLayout.CENTER);
cheers!!

How to make a transparent java applet?

No. But consider making the applet paint a background that matches (in colour and texture) the background of the web page in which it's being displayed.

Re: Help with Java school program

Hi, I've been trying to figure out how to make my DoubleCanvas java program to work. What I'm supposed to do is have a left canvas and a right canvas. In the middle of the applet is a button panel that can select to either draw on the left, right, or both canvases. We have a main DoubleCanvas applet class, then each canvas is drawn from a MyCanvas class. My problem is I don't know how to switch from one canvas to the other canvas from the MyCanvas class.
Any help would be much appreciated. Thanks. :)

Hi, sorry. I didn't want to clutter the page with stuff that might be wrong. This is my DoubleCanvas applet class in the works. I'm not sure I did the listeners correct. And I haven't gotten to add the Checkbox event stuff in the MyCanvas class in yet, because I don't know how to make the checkboxes activate a particular canvas. If you feel I should post the MyCanvas class please let me know, it's somewhat long.

How to parse XML to Java object... please help really stuck

Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
     id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
     <family> Yoshi </family>
     <given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, Yo

Hi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...
