Hi Jake,
Firstly, thanks a lot for your time.
I have the following model code:
public class MyPage extends ComponentGateway {
private static XMLCFactory xmlcFactory = null;
public Document handleDefault (BComponent root, ViewContext vc,
HttpServletRequest req, HttpServletResponse resp) {
if (xmlcFactory==null) xmlcFactory = new
XMLCStdFactory(this.getClass().getClassLoader(), new StreamXMLCLogger());
XMLObject page =
xmlcFactory.create(mypage.presentation.MyPageHTML.class);
BTemplate templateComp = new BTemplate(new MyPageModel());
templateComp.setView(new
DefaultTemplateView(page.getElementById("MyPage")));
root.addChild(templateComp);
return page;
}
/* MypageModel */
class MyPageModel extends AbstractTemplateModel {
//register the model by name
public String getName() {
return "MyPage";
}
//provide items by key
public Object getItem(String key) {
ViewContext vc = getViewContext();
if (key.equals("Title")) return "MyPage Title";
else if (key.equals("Header")){
XMLObject header =
xmlcFactory.create(mypage.presentation.HeaderHTML.class);
Node headerNode = header.getElementById("header");
return
vc.getElementFactory().getDocument().importNode(headerNode, true);
}
else if (key.equals("Menu")){
XMLObject menu =
xmlcFactory.create(mypage.presentation.MenuHTML.class);
Node menuNode = menu.getElementById("menu");
return
vc.getElementFactory().getDocument().importNode(menuNode, true);
}
else if (key.equals("Footer")) {
XMLObject footer =
xmlcFactory.create(mypage.presentation.FooterHTML.class);
Node footerNode = footer.getElementById("footer");
return
vc.getElementFactory().getDocument().importNode(footerNode, true);
}
else if (key.equals("MainText")) {
XMLObject mainText
=xmlcFactory.create(mypage.presentation.MainTextHTML.class);
Node mainTextNode = mainText.getElementById("mainText");
return
vc.getElementFactory().getDocument().importNode(mainTextNode, true);
}
else return super.getItem(key);
}
}
}
As you can see, the above model has combined four html files, viz.
Header.html, Footer.html, Menu.html and MainText.html, into MyPage.html.
Among these html files, Header.html contains some images, Footer contains
some images with external links, and MainText few paraphaphs of text.
The following is my Menu.html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html id="MyPage">
<head><title>menu</title></head>
<body>
<table id="menu" border="0" width="222">
<tr>
<td height="41" width="220"><a
href="http://mydomain.net:8002/mypage"/>
<img height="41" src="graphics/greenHome.jpg" width="220"/>
</td>
<td height="41" width="220"><a
href="http://mydomain:8002/page1"/>
<img height="41"src="graphics/blueHome.jpg" width="220"/>
</td>
</tr>
</table>
</body>
</html>
Now, Menu.html has two buttons, greenHome.jpg and blueHome.jpg, linking
mypage and page1 respectively. What I am trying to do (1) I generate new
pages, replacing MainText.hmtl with new files or content in the model, and
(2) Add a button in Menu.html to hyperlink those files.
(page1, by the way, is just page, all similar to mypage, except the
content of MainText.html).
How I have hyperlinked in Menu.html file now may not work (they are
exactly like I have done in Footer.html to hyperlink external URLs), if I
run this program in different hosts. So, I guess, using BLinks may be the
solution, but I do not know how to use it here.
In the following code in the model, relating to Menu.html:
else if (key.equals("Menu")){
XMLObject menu =
xmlcFactory.create(mypage.presentation.MenuHTML.class);
Node menuNode = menu.getElementById("menu");
return
vc.getElementFactory().getDocument().importNode(menuNode, true);
}
It simply add the complete DOM tree of a table into MyPage.html. How
can I get into Button ie <a level and do some linking? What changes do I
have to do in Menu.html?
Thanks once again, and my apology that I may have included unnecessary
detail here, or may not have include necessary ones.
