Saxon throwing java.net.SocketException:

Ubuntu 10.4 JRE 1.6.0_26

SaxonHE9.3.0.5

I have a very simple script that extracts the text content from a valid html file

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:html="http://www.w3.org/1999/html"
      version="2.0">
    <xsl:output method="text" encoding="utf-8"/>
</xsl:stylesheet>

running this script in Oxygen produces the expected output.

running this on the same PC on the command line using the same version of java and saxon like so

java -jar lib/saxonHE-9.3.0.5.jar -o:build/etemp/html_1.txt -s:build/ebook/epub_sh-tei.html -xsl:xslt/htm2text.xsl

outputs the following error

Error java.net.SocketException: Unexpected end of file from server Transformation failed: Run-time errors were reported

below is the verbose output from java

Please do not ask the same question on every forum you can think of. Choose the most appropriate, ask there, and only turn elsewhere if you get no response. Asking in multiple places is wasting the time of people who volunteer to help you, because they can't see that the question has already been answered elsewhere. Downvoting the question for this reason.

For those looking for an answer:

The answer to this question was that the parser was trying to get the html dtd from here http://www.w3.org/1999/html as stated in the style sheet.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns:html="http://www.w3.org/1999/html"
      version="2.0">
    <xsl:output method="text" encoding="utf-8"/>
</xsl:stylesheet>

W3 was ignoring the request and java threw an exception. The parser gave no indication that it was requesting the dtd nor that it had not received the dtd. Leaving the user in the outer darkness as to why the transformation failed. Very bad behavior for the parser!

The solution was to tell the parser to use a local dtd, via a catalog like so, this is from a ant script:

<macrodef name="saxon_use_catalog">
    <attribute name="input"/>
    <attribute name="stylesheet"/>
    <attribute name="output"/>
    <sequential>
        <echo>Transforming @{input} to @{output} using @{stylesheet} </echo>
        <java classname="net.sf.saxon.Transform" fork="true" failonerror="true">
            <jvmarg value="-Dxml.catalog.files=lib/xhtml11/dtd/xhtmlcatalog.xml" />
            <classpath>
                <pathelement location="lib/saxonHE-9.3.0.5.jar"/>
                <pathelement location="lib/resolver.jar"/>
                <pathelement location="lib/xhtml11/dtd/xhtmlcatalog.xml"/>
            </classpath>
            <arg value="-r:org.apache.xml.resolver.tools.CatalogResolver"/>
            <arg value="-x:org.apache.xml.resolver.tools.ResolvingXMLReader"/>
            <arg value="-y:org.apache.xml.resolver.tools.ResolvingXMLReader"/>
            <arg value="-s:@{input}"/>
            <arg value="-xsl:@{stylesheet}"/>
            <arg value="-o:@{output}"/>
        </java>
    </sequential>
</macrodef>

The resolver jar and catalog I used were packaged with Oxygen.
