GeoTools

XMLNS namespaces and serialization

Details

  • Type: Bug Bug
  • Status: Open Open
  • Priority: Critical Critical
  • Resolution: Unresolved
  • Affects Version/s: 2.2.2
  • Fix Version/s: 2.4.6
  • Component/s: xml
  • Labels:
    None
  • Environment:
    JRE 1.5.0_12 and later

Description

Seems latest JREs are more strict to XML serialization. If AttributesImpl class is used to be passed for encoding of "xmlns:sld=http://www.opengis.net/sld" like attributes in XML tags then XMLNS namespace must be declared explicitly:
------------------------------------------------------------------------------------------------------
atts.addAttribute("http://www.w3.org/2000/xmlns/", null, "xmlns:sld", "CDATA", "http://www.opengis.net/sld");
------------------------------------------------------------------------------------------------------

This affects TransformerBase class and stuff around it.

I see you're fixing these things on 2.2.x. Nice. If you port the fix to 2.3.x and trunk close the issue, otherwise please don't close it, eventually reassign it to some other geotools developer, otherwise we'll end up fixing this again from scratch (that has happened multiple times so far)

Here is Vitali's origional email on this topic:
With installed Java 1.5.0_12 SLDTransformer stopped to output xmlns:*
attributes in first XML tag of SLD. After that SLD is not readable back to
the object tree because Java default SAX parser just throws
XMLParseException.

Before it was Java 1.5.0_04. Debugging shows that internally in XML
serializer (in Java classpath) these attributes in first tag are ignored.
There are some comments and javadoc in source files sending to play with
http://xml.org/sax/features/namespace-prefixes
http://xml.org/sax/features/namespace

options.


Suspect that old hack with startElement().. where xmlns attributes is not
enough with modern parsers?
