Camel XQuery - Saxon
Hi,
Saxon allows for java methods to invoke from XQuery, for example;
declare namespace math=java:java.lang.Math;
let $r := math:random()
return $r
It would appear that this doesn't work out of the box in the Camel
implementation. Does anyone know how to enable this?
Thanks

Re: Camel XQuery - Saxon
Posted by Phobos <sm...@gmail.com>.
Hi,
I've tried the following;
Define myNamespaces in the context as a spring bean;
<bean id="myNamespaces" class="java.util.HashMap">
<constructor-arg>
<map>
<entry key="math" value="java:java.lang.Math" />
</map>
</constructor-arg>
</bean>
Route;
> from("direct:transform-queue").
> to("xquery:transform.xqy?namespaces=#myNamespaces").
> to("log:com.mydomain.TransformerRoute?level=INFO");
transform.xqy;
<Test rand="{ math:random() }" />
The XQuery processor appears to resolve the map as no type mismatch
exception is thrown but when processing the XQuery the following exception
is still thrown;
org.apache.camel.RuntimeExpressionException:
net.sf.saxon.trans.XPathException: Cannot find a matching 0-argument
function named {java:java.lang.Math}random()
Thanks

Yeah if that is possible, then that would IMHO also be the best solution.

I suppose this declares the namespaces through the StaticContext. But
according to the XQuery spec, declaring them in the Prolog (leading section
of the XQuery expression file) should have the same effect. And it's easier
to maintain in the long run.

I just checked the code of camel-xquery component, it supports to set the namespaces through the uri.
myNamespace is map instance which you need to bind it into CamelContext Registry.
from("direct:transform-queue").
to("xquery:transform.xqy?namespaces=#myNamespace").
to("log:com.mydomain.TransformerRoute?level=INFO");

Re: Camel XQuery - Saxon
Posted by Raúl Kripalani <ra...@evosent.com>.
In theory, there should be nothing to configure at the Camel level if you declare the namespace in the Prolog of the template. The XQuery template should be self-sufficient and independent from the runtime.
Have you tried placing the namespace URI inside quote marks? I think you're just missing those. Try:
declare namespace math="java:java.lang.Math";

Raúl.

Re: Camel XQuery - Saxon
Posted by Phobos <sm...@gmail.com>.
In principle that would appear to work as a filter, however in this instance
I am using the XQuery template as a transformer endpoint. For example;
from("direct:transform-queue").
to("xquery:transform.xqy").
to("log:com.mydomain.TransformerRoute?level=INFO");
Is there a way to inject custom namespaces into the above example (as an
endpoint)?
Thanks

Re: Camel XQuery - Saxon
Posted by Raul Kripalani <ra...@evosent.com>.
Try this:
XQueryBuilder.xquery("myScriptWhichUsesTheMathPrefix").namespace("math",
"java:java.lang.Math").
For example, within a filter() DSL:
.filter(XQueryBuilder.xquery("myScriptWhichUsesTheMathPrefix").namespace("math",
"java:java.lang.Math"))
....
You can also use this import to avoid having to specify the class name:
import static org.apache.camel.component.xquery.XQueryBuilder.xquery;
then it becomes:
.filter(xquery("myScriptWhichUsesTheMathPrefix").namespace("math",
"java:java.lang.Math"))
....
Does that help?

Re: Camel XQuery - Saxon
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Yeah this is likely not supported currently.
Take a look in the XQueryBuilder and see what code it takes to
register that prefix / function.
Maybe we can improve the component to support that.
The problem would also be find a good way to configure this in Java
and XML DSLs.
