RE : [jelly] escape quote in litteral xpath.
Thank, but I have to explain that this expression must be in a XML attribut
like
j:set var=myElement value=${wrapper.select(/path/to/[EMAIL PROTECTED] =
'attribute_name'])}/
It's pretty difficult no ?

RE : RE : [jelly] escape quote in litteral xpath.
Yes, I know this late
j:set var=path value=/path/to/element/[EMAIL PROTECTED] = 'attribute_name']/
j:set var=myElement value=${wrapper.select(path)}/
works perfectly.
But what I was searching was escaping quote in jellyExpression (so jexl)
so I could write the two lines in one line as :
j:set var=myElement value=${wrapper.select('/path/to/element/[EMAIL PROTECTED]
= \'attribute_name\']')}/
but It seems imposible.
Thank, I will use the two-lines method.

No,
j:set var=path value=/path/to/element/[EMAIL PROTECTED] = 'attribute_name']/
j:set var=myElement value=${wrapper.select(path)}/
should work as far as I can tell.

[Jelly][HowTo] Catch var call
Hello everybody.
First my concern :
- write rule about variable value construction
- be sure rule are executed in proper order
Look at that
!-- Rule Set --
ruleSet var=myRuleSet
rule var=first
doSomething/
rule
rule var=middle
doSomethingWithRuledVariables
blabla middle use ${first} and ${last}/blabla
/doSomethingWithRuledVariables
rule
rule var=last
doSomethingElse/
rule
/ruleSet
So if I want to be sure ${middle} is computed with real ${first} and
${last}, I have to be sure rules are fired this way :
- rule for ${first} FIRED = ${first} computed
- rule for ${middle} NEED ${last} =
rule for ${last} FIRED = ${last} computed
${middle} computed.
So I have to catch ${last} call to be sure.
Are you OK with this ?
So I have to extend jellyContext to override getVariable familly method.
Everybody is OK with this or someone has another point of view ?
PS : And what about a String manipulation tag library like uppercase,
lowercase, normalize or strip-diacritic-char ?

[configuration] Mutability of CompositeConfiguration
I am unsure whether CompositeConfiguration is mutable or immutable.
From the documentation, I was under the impression that it would be
immutable. By this, I mean that if you load it with configuration and then
add more configuration, if you repeat the same key in both sets of
configuration, the first definition of the key is the one that will be
returned when you look-up its value.
If the second configuration updated the value of the key which had been
initially defined in the first configuration, I would consider it to be
mutable.
I am trying to load configuration from a set of files but allow this
configuration to be overridden by System Properties. So I am loading the
system properties first and then adding the configuration from files. My
understanding is that configuration settings in CompositeConfiguration
would be immutable but my experience seems to be that this is not the case.
If I load a system property which is also included in the configuration
files, the one from configuration files is what is subsequently available.
Is this the behaviour that I should expect?
Here is the code that I am using.
CompositeConfiguration compositeConfiguration = new
CompositeConfiguration();
// load system properties - these override all others
Properties properties = System.getProperties();
Enumeration e = properties.propertyNames();
String key;
while (e.hasMoreElements()) {
key = (String) e.nextElement();
compositeConfiguration.setProperty(key,
properties.getProperty(key));
}
// load file based properties
ConfigurationFactory factory = new ConfigurationFactory();
factory.setConfigurationURL(aConfigFileURL);
Configuration configuration = factory.getConfiguration();
compositeConfiguration.addConfiguration(configuration);
So if I specify a system setting key/value pair of keyX=valueY where
configuration in my files sets keyX=valueZ, what should I get when I
retrieve the value after this set-up?

Is there a way to turn on schema validation when parsing an XML config file with Digester 1.6. To do validation, I would recommend creating your own parser instance, setting it up using the standard JAXP apis (or parser-specific APIs) then using the Digester constructor that takes a parser parameter - or call parser.parse(source, digester). Yes, there are methods on the digester class to configure some parser features, but it seems more confusing to me to use these than to use *standard* apis for parser configuration. Well, we should try to fix that if you think the method are useless (who did that?? ;-) ). A good example on how schema can be used can be viewed here: http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-catalina/catalina/src/share/org/apache/catalina/startup/DigesterFactory.java?rev=1.6.2.2only_with_tag=TOMCAT_5_0view=markup Thanks -- Jeanfrancois Regards, Simon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
problem with printing out directories
Hi,
Is there something wrong with this piece of code?
I am trying to print a few directories existing in the local machine, but the piece of
code doesnt seem to work. However when the File is given this argument ../ then it
works!!
File dir = new File(../abc);
String[] files = dir.list( DirectoryFileFilter.INSTANCE );
for ( int i = 0; i files.length; i++ ) {
System.out.println(files[i]);
}
Am I making a mistake?
thanks

Re: [ANNOUNCMENT] Digester 1.6 Released
hi Matthias (i think that this is in the release notes but maybe i didn't explain this very well.) the rss implementation is really an example of digester (as opposed to core digester functionality). so, we decided that it would be better not to include the classes in the actual digester jar. they haven't changed in ages (the ones from the 1.5 jar will work fine with 1.6 digester) but the recommended approach is to download the digester source release (which still contains the classes) and use the build script found in digester/example/rss. hopefully ant dist should create a jar containing the rss application. if you need to patch up the script, please consider donating your improvements back to apache. (opening a bugzilla report is the best way to submit a patch). if not, then please consider adding something to the wiki (http://wiki.apache.org/jakarta-commons). you'll need to sign up with an email address before you can edit. BTW if you're looking for more modern RSS versions, kevin's working on something RSS-related in the sandbox which is probably worth a look. - robert On 15 Sep 2004, at 08:17, Matthias Wessendorf wrote: Hi Robert, I just saw the new Javadoc of Digester, but I don't saw the *org.apache.commons.digester.rss*-package.
