The code snippet is given below.
private static class MyRouteBuilder extends RouteBuilder {
//private Namespaces responseRouteNamespaces = new
Namespaces("xyz","http://www.abc.com/pats/xyz/v1";);
private Namespaces responseRouteNamespaces = new
Namespaces("xyzwrapper", "http://www.xyz.com/abc/xyz/wrapper/v1";);
@Override
public void configure() throws Exception {
from("direct:test")
.log("Received response from downstream as XML: ${body}")
.choice()
.when(responseRouteNamespaces.xpath("/xyzwrapper:WrappedAdoResponse"))
.log("Logging after xpath")
.otherwise()
.log("Logging otherwise")
.end();
}
}
Not sure why it is failing. Is it because of multi threading issue. Is camel
xpath is thread safe?
