Re: [Digester] HTML entity decoding?
Hello Otis,
For the second form you'll need to hook a DTD to do so. A DTD
declaration in your header pointing to a DTD which defines these
entities I am no expert in Digester but I believe that it is the only
way to do so. At least according to the XML specs.
Here's a text pointing to such a DTD:
http://www.w3.org/TR/xhtml-modularization/dtd_module_defs.html#a_xhtml_character_entities
Note that opening the file with a validating parser will certainly
grumble about all sorts of undeclared elements, this is ok, it does
not prevent parsing but is, indeed, a validation error.
However you get the entity-expansion.
Note that using the first form, which contains an *escaped* entity,
there's nothing to do! You'd have to match them manually ("re-
entrantly") into a parser that parses entities properly.
paul
PS: I would feel lucky not to have been blown away the XML parsing in
the second case as a normal XML parser does: missing entity
declaration means unparseable XML while missing element declaration
means much less a dangerous thing.

I need to use a HTTP proxy on the executing machine. When I try to load the XML configuration, also with setValidate() to false I get a ConfigurationException with the message: Unable to load the configuration. When removing the DTD statement the configuration loads just fine. So: is Apache commons-configuration HTTP proxy aware? Does it use the actual JVM settings? I also tried to use the -Dhttp.proxyHost system properties settings with no success. So, how to do it? Btw. machine is WinXP and I'm using Eclipse as IDE with m2eclipse for Maven support. Thx Chris Hm, good question. XMLConfiguration does not load the DTD on its own, but relies on the XML parser used. The parser itself is obtained using a default DocumentBuilderFactory. I would expect that the XML parser understands the proxy-related system variables and uses them if they are set. (Note that the DTD has to be loaded in any case, even if validation is disabled, because it might contain entity definitions that have to be resolved.) For performance reasons it would be better not to load the DTD from a HTTP server, but ship a local copy with your application. You can put it somewhere on the class path. You can then use the method registerEntityId() of XMLConfiguration to map the public ID of the DTD to a local resource. That way no network access is required.

I'd do it the other way, extend the Context implementation and add
observable functionality since I claim the latter is the simpler bit
(lower case o here, not referring to the java.util class -- minimally,
(a) maintain a list of observers as an instance field, (b) have an
adder method that adds observers to the list and (c) have the notify
method in question iterate over the observers to notify them of the
value change).

Timers don't need JEXL, you can continue using whatever EL you were
using (extend the corresponding Context and Evaluator implementations
-- if you were in fact using Commons JEXL, you'd extend JexlContext
and JexlEvaluator and so on).

Its a bit more of a Java question than an SCXML question, yes. You
could post to any Java forums / try search engines.

Re: [SCXML] getting set datats in the datamodel
Hello
So I´m back here again.
My problem now is that I don´t know how to notify.
I looked at the solution suggested below since I thought it would be the
easiest and best looking way to implement this.
The way my first solution worked was to use Observer and Observable. Since
Observable is a class I could not extend SimpleContext aswell (since
multiple inheritance from classes is not ok in java) so i just "copied"
SimpleContext instead since it only implemented two Interfaces, extended
Observable and modifyed it according to my liking. The problem then was that
to user timers (as I was asking about in another thread) and they use JEXL.
So to make the timers work I have to use an JEXL or JEXL extended class. And
there goes my Observable.
I am aware that this might be a java question instead of a SCXML question
and if so I apologise. Maybe you can see something that I have missed or
help me with where I should post this question. I´ve stared a bit too long
at my code by now. Is there another way to do this?

Quotes are only allowed in quoted strings. From the Javadoc:
"Each token may be surrounded by quotes. The quote matcher specifies
the quote character(s). A quote may be escaped within a quoted section
by duplicating itself. "

StrTokenizer not handling quotes correctly?
I am trying to use StrTokenizer for some parsing and I am probably not using
it correctly.
Let's say I have this string:
11"a,b"11,22"c,d"22"
I would like to split it by the comma ",", but ignoring any commas embedded
in quotes. I try this:
String test = "11\"a,b\"11,22\"c,d\"22";
StrTokenizer str = new StrTokenizer(test,',','"');
String[] tokens = str.getTokenArray();
for(String t: tokens) {
System.out.println(t);
}
and expect to have two strings print out:
11"a,b"11
22"c,d"22
but instead I get 4 :
11"a
b"11
22"c
d"22
It seems the tokenizer is splitting on the comma, even if it is embedded in
quotes.
I tried different options on the StrTokenizer, but not been able to get it
to work correctly.
Any idea as to what am I doing wrong? Using latest version 2.4.
