Ant xslt task seems to ignore xmlcatalog for mapping dtds
Hi,
I'm trying to use the xslt task in Ant to validate some xhtml files. The xhtml files start with a <!DOCTYPE ...> line to indicate the xhtml version. The doctype refers a DTD, like in following example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns:h="http://java.sun.com/jsf/html">
<h:head>
</h:head>
<h:body>
</h:body>
</html>
The xslt task tries to connect to www.w3.org to fetch the dtd. But I'm behind a firewall so that fails. When I run ant with -v, I get amongst others following message in the stack trace:
java.net.UnknownHostException: www.w3.org
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)
at java.net.Socket.connect(Socket.java:529)
at java.net.Socket.connect(Socket.java:478)
... some stuff about HttpClient and HttpURLConnection

at com.sun.org.apache.xerces.internal.impl.XMLEntityManager.startDTDEntity(XMLEntityManager.java:1282)
...
I have read about the xmlcatalog element that can be used to map the dtd-id to a local file. I have tried to set it up as follows:
<xmlcatalog id="xhtmlDTDs">
<dtd publicId="-//W3C//DTD XHTML 1.0 Transitional//EN" location="${product.home}/dtd/xhtml1-transitional.dtd"/>
</xmlcatalog>
<target name="validate-xhtml">
<mkdir dir="${module.home}/validate-xhtml-rslt}"/>
<xslt
basedir="${module.home}/src/webroot"
destdir="${module.home}/validate-xhtml-rslt"
style="${module.home}/validate-xhtml.xslt"
includes="**/alex.xhtml"
>
<xmlcatalog refid="xhtmlDTDs" />
<mapper type="glob" from="*.xhtml" to="*.html"/>
</xslt>
</target>
But despite the xmlcatalog being defined, I still get the very same exception.
Note that I'm using ant 1.7.1 which is bundled with eclipse and I'm running it with a JRE 1.6.0.22. I have also added resolver.jar from apache xml-commons to the classpath but it does not help neither.
Note that this is the output from ant with -v option:
validate-xhtml:
[mkdir] Skipping P:\srcSDC\idm\modules\identitypublicweb\validate-xhtml-rslt} because it already exists.
[xslt] Using class org.apache.tools.ant.taskdefs.optional.TraXLiaison

[xslt] : Error! www.w3.org
[xslt] : Error! com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: www.w3.org
[xslt] Failed to process null
After that comes the stacktrace with the host not found exception
Any help or hints in fixing this are appreciated.
Thanks and kind regards,
Alex
