well, I use it in my servlets too, but don't have anything that uses 
RMI.  yeah, some examples might be good.  They could make it to the 
website.

Yea, i know and try to use it. The problem was with my application.
I have included html-tmpl-java into java servlets and have any
rmi-components,
that generates my hashtable for the templates. So i must run about all
entries and add the sessionID. But this is not the problem if i can get
the next version of html-template with the cool new feature ;-)

If you interested for the integration from html-template into
java-servlets
i can give you a short example.

This is basically what global_vars in the perl version of HTML::Template 
does.  As of now, it's not possible in the java version, and my initial 
intent was not to support it, but it seems like there are people who 
would want it in, so the next version would most likely have global_vars 
support.

For now, you'll have to use a workaround, and add sessionID to each of 
your loop elements.  Something like this:

Vector v = Newsmanager.getNews();
for(Enumeration e = v.elements(); e.hasMoreElements();) {
	Hashtable h = e.nextElement();
	h.put("sessionID", sessionID);
}

I'll add support for it in the next version, and you're welcome to see 
if you can too.

[htmltmpl-java] access to tmpl_var inside of tmpl_loop

[Thomas W. <tw...@im...>]

Hello,

i try following java code fragment:

.....
// a normal template variable
template.setParam("sessionID",sessionID);
// a template loop
template.setParam("newsloop",Newsmanager.getNews());
....

in html:
.....
<tmpl_loop newsloop>
news: <tmpl_var news><br>
sessionID: <tmpl_var sessionID>
</tmpl_loop>
.....

the problem is, that the var "news" is correct set
inside the loop, but the outside of the loop declared
variable "sessionID" is not set.

How can i access tmpl_vars inside the
loop, which are not declared in the loop-hashtable?

What you think about it?

[htmltmpl-java] [Announce] ver 0.1.0 of HTML.Template.java released

[Philip S T. <phi...@gm...>]

Version 0.1.0 of HTML.Template.java has just been released.  It's still 
a development release, but is getting stable.  A few bug fixes, and 
enhancements.  Also added the Filter interface.

Following is the ChangeLog

ver 0.1.0

- supports Hashtable style constructor parameter
- Now also accepts Booleans and Integers in constructor parameters, not just
  Strings
- path parameter accepts a single String as well as an array of Strings
- setParam also accepts int, boolean, Integer and Boolean
- added Filter interface
- fixed bug that prevented file handle from working (thanks to Marcos Ramirez)
- fixed case bug with include filenames

I will have changed the constructor in the next version to support both 
single valued paths as well as array paths, but for now, just use an 
array.

[htmltmpl-java] [Announce] Version 0.0.9 is out

[Philip S T. <phi...@gm...>]

Well, version 0.0.9 is out, which fixes the case bug, and also adds some 
features.

Changelog:

1 Jul 2002
ver 0.0.9

- supports reading from file handle
- no longer adds newline character to items passed in arrayref
- added escape=quote parameter for tmpl_vars - still waiting for sam
to put it into HTML::Template.  This may change.
- fixed bug that caused NullPointerAssignment if closing tags were
not in lowercase


I need help finding bugs in the docs, and also suggestions to improve 
the howto on the site.  Any suggestions?

Were you the one who asked this question on the users forum?  Anyway, 
I'll answer it here too.  Yes, you can.

You'd have to have something like this:

Hashtable(
	loop1  =>  Vector1 (
				Hash1(loop2  =>  Vector2)
				Hash2(loop2  =>  Vector3)
				Hash3(loop2  =>  Vector4)
			   )
	 )

Of course, Hashtable, Hash[1-3] would also have other elements.  The 
first hashtable is optional, since it is created inside the template 
anyway.

So, java would be like this:

Template t = new Template(...);

Vector v = new Vector();
for(outer_loop) {
	Hashtable h = new Hashtable();
	h.put("field1", value1);
	...

	Vector v2 = new Vector();
	for(inner_loop) {
		Hashtable h2 = new Hashtable();
		//populate h2
		v2.addElement(h2);
	}
	h.put("loop2", v2);
}

t.setParam("loop1", v);

And set any other params as you want them.

[htmltmpl-java] Help!

[James W. <jam...@ho...>]

Hi,
Can I embed one loop into another? and how to do it in java side?

<tmpl_loop loop1>
    ....
    <tmpl_loop loop2>
    ...
    </tmpl_loop>
</tmpl_loop>

Thanks.

This isn't possible as it will require a two pass parser - that isn't
going to happen.  This is a question that's been asked several times on
the HTML::Template - perl mailing list, and the general consensus is
that it will never be a part of the template module itself, but it can
be done through filters.

Filters aren't implemented yet in H.T.j, but will be soon, so hold on a
bit.

Thanks,

Philip

Nope, it was a bug in the case handling for closing tags.  It's fixed in
CVS.

not that I know of.  encoded urls have to be generated by the servlet
engine, so the only way to do it is through your java program.  the
template has no logic in it.

well, this is fixed in CVS if anyone else is interested, and will be in
0.0.9 when it comes out sometime next week.

I've also included the escape=quote param for tmpl_var, but whether it
stays in or not depends on whether sam's going to put it into
HTML::Template or not.

[htmltmpl-java] option for the next release

[Thomas W. <tw...@im...>]

Hello,

I using html-tmpl intensitiv in many Project.

Please look at the following code and let me know
if one have an idea to make this work:

<tmpl_include <tmpl_var hostname>/file.tmpl>

So I will include on file and the path of the
template file stands in an template-variable.

Thanks,

[htmltmpl-java] Upper Case Tags and Encoded URLs

[ralf u. <rul...@we...>]

Hi,

I recently downloaded HTML-Template-Java and think its great to have it =
for Java as well.
When I startet to play around a little I found that my templates dont =
work if I use the template tags in upper  case; lower case just works =
fine.=20
As I guess from the docs HTML-Template uses case insensitivity as =
default, so uppercase tags should work. Did I forget something?

My second question concerns sessiontracking. I plan to develop a =
controller servlet that takes care of sessiondata. As long as I use =
cookies to store sessions I can keep my templates as they are, but what =
if users dont allow cookies? I then would have to use url-rewriting and =
put something like

<a href=3D"<TMPL_VAR encoded_url>">=20

in my templates, which forces me to store url in a servlet I guess. Is =
there any other better solution for this?

Yours,

Ralf

[htmltmpl-java] News and updates

[Philip S T. <phi...@in...>]

Well, I was planning on releasing version 0.0.4 sometime this week, but
I had a Monday off and through in loads of features and even a new
Parser module.  The next version will now most likely be 0.0.8, with
very little left to bring it up to 0.1.0.

As far as discussions go, Sam says it's okay to discus Template issues
on the HTML::Template mailing list, so we'll probably stick to that.
We'll keep this list for HTML.Template specific stuff, java related,
bugs, etc.
