Parsing WMS-Capabilities
------------------------
Key: GEOT-1858
URL: http://jira.codehaus.org/browse/GEOT-1858
Project: GeoTools
Issue Type: Bug
Components: ext wms
Affects Versions: 2.4.4
Environment: java 1.5, windows xp
Reporter: Thomas van Gemmeren
Assignee: Richard Gould
Using the new stable version (2.4.4) of geotools we hvae problems to pars a
wms-capabilities file. There were no problems with gt2.2.2RC3.
The problem is the use of the namespace attribute in the WMS_Capabilities-tag.
This works fine
<WMS_Capabilities version="1.3.0">
This leads to an Exception
<WMS_Capabilities version="1.3.0" xmlns="http://www.opengis.net/wms";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/wms
http://schemas.opengis.net/wms/1.3.0/capabilities_1_3_0.xsd";>
Omitting xmlns="http://www.opengis.net/wms"; also works:
<WMS_Capabilities version="1.3.0" xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/wms
http://schemas.opengis.net/wms/1.3.0/capabilities_1_3_0.xsd";>
The Exception was

There is also the nested Exception:
Should not have any children - this is a simpleType at Line 9 Col 29 tag is:
ContactPersonPrimary
It seems something to do with the handlers-stack in
org.geotools.xml.XMLSAXHandler. The stack holds the wrong members -> parent
should be 'name'-Tag.
This is wrong. It should be 'ContactInformation'. 'name'-Tag is type simple ->
Should not have any children.
