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?
