[jira] [Commented] (XERCESJ-1654) Add support for properties set by JAXP in the JDK (secure-processing, accessExternalDTD and entityExpansionLimit)

["Soeren Schmidt (JIRA)" <xe...@xml.apache.org>]

    [ https://issues.apache.org/jira/browse/XERCESJ-1654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14506737#comment-14506737 ] 

Soeren Schmidt commented on XERCESJ-1654:
-----------------------------------------

In my code the missing accessExternalDTD property seems to cause an error. When using "localhost" everything works fine but when using the computer's name (gk4252) the transformation fails and an error shows up:

{code}
Compiler warnings:
  WARNING:  'org.apache.xerces.jaxp.SAXParserImpl: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.'
ERROR:  'Could not compile stylesheet'

>          Issue Type: New Feature
>    Affects Versions: 2.11.0
>         Environment: Problem noticed with:
> * jdk1.7.0_71.jdk
> * jdk1.8.0_25.jdk
>            Reporter: Vincent Massol

> I have tons of the following warnings in my console when doing an XSLT transformation:

> Warning:  org.apache.xerces.parsers.SAXParser: Property 'http://www.oracle.com/xml/jaxp/properties/entityExpansionLimit' is not recognized.

>         transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
>         StreamResult result = new StreamResult(new StringWriter());
>         StreamSource source = new StreamSource(new StringReader(content));
>         transformer.transform(source, result);
>         return result.getWriter().toString();
>     }
> {code}
> According to what I read at https://issues.apache.org/jira/browse/RAT-158 and at http://docs.oracle.com/javase/tutorial/jaxp/limits/limits.html this seems to have been caused by some changes introduced in the JDK and that XercesJ doesn't support yet.
> Thus this issue is about adding support for them.
> Thanks!
