NewInstance(String)

schema language and return it.

static member NewInstance : string -> Javax.Xml.Validation.SchemaFactoryParameters
- schemaLanguage
- String
Specifies the schema language which the returned SchemaFactory will understand. See the list of available schema languages for the possible values.
Returns
New instance of a SchemaFactory
- Attributes
Exceptions
If no implementation of the schema language is available.
If the schemaLanguage parameter is null.
Remarks
Lookup an implementation of the SchemaFactory that supports the specified schema language and return it.
To find a SchemaFactory object for a given schema language, this method looks the following places in the following order where "the class loader" refers to the context class loader:
<ol> <li> If the system property "javax.xml.validation.SchemaFactory:<i>schemaLanguage</i>" is present (where schemaLanguage is the parameter to this method), then its value is read as a class name. The method will try to create a new instance of this class by using the class loader, and returns it if it is successfully created. </li> <li> $java.home/lib/jaxp.properties is read and the value associated with the key being the system property above is looked for. If present, the value is processed just like above. </li> <li>
The class loader is asked for service provider provider-configuration files matching javax.xml.validation.SchemaFactory in the resource directory META-INF/services. See the JAR File Specification for file format and parsing rules. Each potential service provider is required to implement the method:
{@link #isSchemaLanguageSupported(String schemaLanguage)}
The first service provider found in class loader order that supports the specified schema language is returned. </li> <li> Platform default SchemaFactory is located in a implementation specific way. There must be a platform default SchemaFactory for W3C XML Schema. </li> </ol>
If everything fails, IllegalArgumentException will be thrown.
<strong>Tip for Trouble-shooting:</strong>
See java.util.Properties#load(java.io.InputStream) for exactly how a property file is parsed. In particular, colons ':' need to be escaped in a property file, so make sure schema language URIs are properly escaped in it. For example:
http\://www.w3.org/2001/XMLSchema=org.acme.foo.XSSchemaFactory
