Re: extended xslt task - use URIResolvers to create DependSet
BTW, here is the output from ant -diagnostics. As I mentioned before, I do have the class (org.apache.tools.ant.taskdefs.optional.CachingTraXLiaison) that is not being found in the ant-nodeps.jar (I even unzipped it to check). I modified the org.apache.tools.ant.taskdefs.XSLTProcess to choose the new liaison class if it sees an xslcache attribute on the xslt task, which occurs. Output includes 'optional tasks : not available', but I have every jar necessary in the $ANT_HOME/lib dir.

Re: extended xslt task - use URIResolvers to create DependSet
Hi again, What do you think about using a xml cache file like below (xml instance followed by XML schema). Since the same XSL (xsl:include/ xsl:import) and XML (from the doc/document function) files can be used in several different, it would make sense to allow the cache file to be reused in multiple xslt tasks. Using an XML doc with IDs and IDREF can reduce the redundancy of the same file(s) being reused in multiple and/or different transformations. (and speed up finding the appropriate reference) perhaps this is how the xslt task is extended in a build file like so: The existence of this attribute (whatever it is named :) ) indicates the use of the caching/spying trax liason ? Here is an example instance of a reusable cache doc followed by an XML schema: 78f43t84t y8734qr 437hr88qr3 c7834fr4g hq378d43 dh78234 http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified"> type="xs:anyURI"/> type="xs:anyURI"/> type="xs:anyURI"/> On Oct 27, 2008, at 4:37 PM, Dominique Devienne wrote: On Mon, Oct 27, 2008 at 11:51 AM, Robert Koberg <[EMAIL PROTECTED]> wrote: I would love to use a properties implementation that [...] Is something like this available now in Ant?

Guessing, since I didn't follow the discussion: nowhere.

How would you do it?
Make it an attribute with some reasonable default (your descriptions
sounds good, but how would you define "per xslt task"? use the
stylesheet's name?). See the selector for example.
The templates' URIResolver could work like the selector.
But the transformer's URIResolver is different. Since it is at a per
transform level it is not really the same (where the transform can
happen over all XML files in some src dir).
I would love to use a properties implementation that allowed getting a
subset of properties based on 'startsWith' see:
http://commons.apache.org/configuration/apidocs/org/apache/commons/configuration/AbstractConfiguration.html#getKeys(java.lang.String)
?? I did a search in the ant source and did not find
'org.apache.commons.configuration'
Example props file:
main1.xsl.templates.import1.xsl = 6873gf43gf
main1.xsl.templates.include1.xsl = 7fg34gry
main1.xsl.transformer.mainSource1.xml.abc.xml = 823478fr87134
main1.xsl.transformer.mainSource1.xml.foo.xml = 1y83gf8734
(probably using paths in the key names ??)
So, for example,
SomeImplOfAbstractConfiguration.getKeys("main1.xsl.templates") returns
the keys to check for the templates recomplile and to perform the
transform.
Is something like this available now in Ant? If not, would the commons
configuration be OK as a dependency? I bet it would be useful in other
places ??
Definitely open to ideas for this :)

extended xslt task - use URIResolvers to create DependSet
Hi, I am looking at extending the xslt task to allow for an enhanced check to determine whether a transform should proceed. Currently there are 2 options for checking whether a transform should proceed. The first just checks the XML and XSL Source against the output file. The 2cnd uses a DependSet. While the DependSet can check the transform at a deeper level, it is inconvenient to set up. Also, in many ways it is impractical, because, for example, a directory containing src XML files could have each reference their own set of files (through the document function). We discussed this a bit on the user list here: http://marc.info/?t=122418056700022&r=1&w=2 Specifically: http://marc.info/?l=ant-user&m=122418293609849&w=2 Basically, I want to use 2 URIResolvers instances (of CachingURIResolver ?) in addition to the the checks for the primary XML and XSL Source: 1. Set one on the TransformerFactory to resolve import/include. If this check turns out to not be up to date, proceed with all transforms skipping the next check. 2. Set another one on the Transformer to resolve document(). If the factories test is up to date, then check the dependencies accumulated through this resolver. These resolvers would gather up their dependencies to track for subsequent transforms. Some questions: * where is the DependSet being checked in the transformation(s)? I can't find it :) * I will need to write to the file system to maintain the cache. What would be a good way of handling this? Should I create a directory in the baseDir for all transforms.

I am trying to use the nested service element in the jar class. It

private void writeServices(ZipOutputStream zOut) throws IOException
{
Iterator serviceIterator;
Service service;
serviceIterator = serviceList.iterator();
while (serviceIterator.hasNext()) {
service = (Service) serviceIterator.next();
//stolen from writeManifest
super.zipFile(service.getAsStream(), zOut,
"META-INF/service/" + service.getType(),
System.currentTimeMillis(), null,
ZipFileSet.DEFAULT_FILE_MODE);
}
}

Re: Resources & Introspection
Hi,
I don't know if this is of interest, but I have made some custom tasks
and types for XSLT. (I would think these could be used to get a resource
from a jar) - for example:
- SourceType (have implemented a XmlDomType) - create a top-level DOM
(dom4j, JDOM, etc...) Document that can be used in multiple XSLT tasks.
The reason was to avoid reparsing a common XML file for multiple transforms.
- TemplatesType - create a top level Templates object that can be used
in multiple XSLT tasks. This type can also take a UriResolverType for
both the factory (resolves xsl:import/includes) and the transformer
(resolves document function calls)
- UriResolverType - can be assigned to a TemplatesType. I have
implemented a FallbackUriResolver which allows you to set a default
directory to look in first and if a file is not found, it falls back to
an alternate directory.
Additionally I have made a Lucene indexer and search type. The search
type can be assigned to a UriResolver where a can be used in the
document function (document('fieldName: matchValue')) and get search
results back as XML for use in the transform.
Of interest?

Apple just doesn't like java :) Strange though that this only comes up with Ant (from what I could find through google). I have not had problems loading XML files from jars or using namespaces in XML processing (the only thing different when using the taglib.xml).

Bus Error - custom task/type - when using taglib.xml
Hi, I have some custom tasks and types. They work fine when I declare them in the build file. But if I use package specific taglib.xml's and reference them by namespace in the build file I get: * a random hang (build stops with no error/exception) when running in -verbose mode * a random Bus Error when not in -verbose mode. By random I mean the hang/error occurs at different places in the build once targets get called (the projects is initialized). I have seen some bug reports about this dealing wiht custom tasks/types and it seems to occur only on Mac OS X (I am using 10.4.2 - the latest) with JDK 1.5.0. I don't know if this is just a failing on Apples part or if it points to something deeper. Is there something known to cause this problem? I don't know how to track this down. Any ideas? thanks, -Rob - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

OK, now I am confused. I have not looked at or used namespaces in Ant yet, but this would seem to be a problem. Would there not need to be a default namespace, otherwise how would the XML parser know what to do? action and http in a default namespace would certainly have totally different meanings to an underlying app. If you use namespaces, does ant require a default namespace. Does ant put a default namespace in behind the scenes?

Particularly JAXP1.3 says you had better ask for validating and namespace aware. So I did. NB: xmlvalidate docs say it is not namespace aware by default. I think it is now, as the factory is. 3. An inadequate number of tests. I'll add more as I use it, but more are welcome. 4. No running of these inadequate tests on anything other than Xerces . Do we ever test ant with other XML Parsers?

Does xerces handle it as well, or is it just a xalan thingy. I'd like an XInclude task if we could pull it off, to make my fairly complex xml workflow tractable (building up WSDL files from multiple XSDs). Xerces handles the XInclude.

Re: FTP Optional Task
Hi, The FTP task (or more likely commons-net) definitely works in mysterious ways (log files don't tell much). I use it to FTP to various servers (windows/? and linux/wu-ftp) and what I have seen is that you have to set up the task differentlty for different types of servers and ftp servers -- by trial and error :( Generally, for linux the following works for me: the above won't work if I set the @timediffauto to true (even though the user has write access) -- one file gets sent and then hangs on the second. I have also tried the modified selector for the fileset (since it doesn't rely on remote files). This fails on linux (I forget the error -- something like command not supported). But using the modified selector with a windows server does work. For windows, even though I have write access, I can't use the @depends=true, but can use the modified selector: best, -Rob Pierre Grimaud wrote: Hi everyone, First of all, many thanks for the great team and the outstanding product (ant!) it delivers for now quite a while. What would I do without ant, I have no clue, but certainly a little less. Anyways... I recently changed my production environment for my personal website so now I have to push files over FTP (across the internet) instead of a shared network drive. I had a quick look at the FTP task and was pleased as it seemed to address all that I needed and some more. After a few days of testing and looking at some forums, it appears I cannot use it productively as of now, for a number of reasons, all of which I am willing to investigate and fix, to the best of my abilities of course. This email is an attempt for a first contact with the Ant developpers community, in order to figure out : 1. how to submit a patch, 2. how to work with the latest (to ensure that my patch could be integrated in the build without versioning and merging nightmares), 3. To make sure no one is working on those same problems, making my efforts effectively useless. Well, I hope I will get an answer to all three of these questions with this email. Disclaimer: I haven't had a look at the source code yet. Let's now get to the core of my problems with the optional FTP task: 1. After transferrig a few files, the FTP task usually fails with one of the two messages: 1a. [SocketException: Connection reset]. I know that the timeouts on my ftp server are quite aggressive (1 min), but I have never had any problems with any of the FTP clients I have ever used, but for Ant's, possibly indicating a possible improvement. 1b. [could not put file: 500 ORT not understood]. This one obviously looks like a communication problem, but for the fact that it never happens on the same file or at the same time. Again, it is the first time I see that message, after some long month of interactnig with my server with other ftp clients. All of these problems could be partially fixed by defining an "auto-retry on fail option", although it wouldn't really address the bugs and it would worsen the following problem quite a bit. 2. The transfer (with the depends="yes" option) is still extremely slow. This is of course due in part to my 128k DSL upload capabilities, but what I have seen in the debug mode seems to indicate that it still could be improved. I will now switch to pure speculation mode. The timestamp check for a file takes around 1 second on my machine, making the entire task pretty sluggish as I have hundreds of files. Instead of checking the timestamp one file by one file, it should be possible to get all the timestamps directories by directories, avoiding unnecessary roundtrips. Of course, this should be optional as it could actually worsen the performance on some cases. Oh well, I will stop here for today and will ask the community if any of these problems are known, or acknowledged, or even in the process of being fixed. If not, I will be happy to proceed.

how to get custom task object?
Hi,
I am trying to create some custom types and tasks, but having a problem
getting back the custom task object to reset some values. My custom task
is coming in as an UnknownElement. I then try to cast to my object using
UnknownElement.getRealThing() (or getTask), but it gives me a null. How
do you get a custom task object?
Task[] tasks = target.getTasks();
Target clonedTarget = new Target();
clonedTarget.setProject(lsb);
for (int i=0; i < tasks.length; i++) {
Task task = tasks[i];
String name = task.getTaskName();
if (name.equals("xsltransform")) {
UnknownElement unElem = (UnknownElement) task;
/*
This next line sets xslTransform == null
*/
XslTransform xslTransform = (XslTransform) unElem.getRealThing();
//XslTransform xslTransform = (XslTransform) unElem.getTask();
xslTransform.setOutputStream(response.getOutputStream());
}
clonedTarget.addTask(task);
}
thanks,
-Rob
p.s. I created a XslTemplates top-level type that can be referenced by
an XslTransform task. This allows for two things; a cache of templates
objects, and the ability to set a URIResolver on the Templates object to
resolve xsl:import/include and a URIResolver on the Transformer object
to resolve calls from the XSL document function. If anyone is interested
I can provide them (though I am sure they would need work...).

[Fwd: howto trigger an Ant build within java]
Hi,
I am looking into using Ant (v1.6.0) more in my webapp so I can offer
offline publishing equivalents. I am transforming some config XML into a
build file. I then want to load that build file into a new
org.apache.tools.ant.Project. The build.xml gets produce properly (it
runs successfully from the command line).
How do I load the build file and create an ant project, then trigger a
particular target to execute? The build file uses only Core Tasks (and
an xmlcatalog). Is there a simple example somewhere? I have tried
searching with google but getting too many hits that don't cover what I
am looking for.
Here is what I have tried:
org.apache.tools.ant.Project antProject = new
org.apache.tools.ant.Project();
AntXMLContext antContext = new AntXMLContext(antProject);
File f = lsbProject.lookup("build.xml").getFile();
System.out.println("build.xml: " + f);
antContext.setBuildFile(f);
System.out.println("project name: " + antContext.getCurrentProjectName());
Vector targets = antContext.getTargets();
for (Enumeration e = targets.elements(); e.hasMoreElements();) {
Target target = (Target) e.nextElement();
System.out.println(target.getName() + " : " + target.getDescription());
}
