I have a class MyResource which implements Resource and can be adapted
to a ValueMap. A custom MyResourceProvider serves up the MyResources
as requested. In my esp scripts, I had just been adapting the resource
to a Map, then accessing the properties through that. But, I'd like to
use MyResource.
If I try to adaptTo(MyResource), the adapt succeeds (I see debug from
MyResource.adaptTo() and I have a non-null javascript object upon
return), but it has no methods or properties.
So, I started writing some debug code to investigate what was going on.
This is the debugging pre-amble in my html.esp...
<%
log.debug("Original Resource: " + resource); // resource displayed as
the resource path
// this loop produces no output
for (i in resource) {
log.debug("\t" + i);
}
log.debug("resource.getPath: " + resource.getPath()); // method call
succeeds, resource path displayed
var resourceObject = resource.getObject();
log.debug("resourceObject: " + resourceObject); // resourceObject
displays as the resource path
// this loop produces no output
for (i in resourceObject) {
log.debug("\t" + i);
}
var valueMap = resource.adaptTo(Packages.java.util.Map);
log.debug("ValueMap: " + valueMap); // valueMap displays as a java
object instance
// this loop shows all the expected methods and fields
for (i in valueMap) {
log.debug("\t" + i);
}
log.debug("valueMap.name: " + valueMap.get("name")); // this
succeeds, displaying the correct name value
var asString = resource.adaptTo(Packages.java.lang.String); //
adapting to String produces MyResource's toString()
log.debug("asString: " + asString); // produces the expected
MyResource.toString() value
// this loop produces no output
for (i in asString) {
log.debug("\t" + i);
}
var myResource = resource.adaptTo(Packages.example.MyResource);
log.debug("MyResource: " + myResource); // myResource displayed as
resource path
// this loop produces no output
for (i in myResource) {
log.debug("\t" + i);
}
%>
It looks like MyResource is getting wrapped in a ScriptableResource
instead of just being converted into a javascript object. Is that
right? How can I get a javascript object equivalent of MyResource?
Confused,
Andreas
