Hello,
I am having problems running some XSD schema generation code in a JSP
environment. In a test (standalone/Java application)environment, the
schema is created without problems. But when I call the class from a jsp
page the schema is not created beyond the minimum namespace declarations.
When this following snippet of code is encountered, it throws the
exception..
XSDElementDeclaration constraint =
xsdFactory.createXSDElementDeclaration();
constraint.setName("Constraint");
constraint.setTypeDefinition(schema.getSchemaForSchema).reso lveSimpleTypeDefinition( "string"));
The culprit is: schema.getSchemaForSchema()..
I have read that you would need to put xsd.resources.jar in the classpath.
But I do have that jar in the WEB-INF/classes directory under my
application. I have also attached the Stack Trace(logged in TomCat) below.
Would be great if someone could point out what might be wrong
