Description

« Hide

Attached in the zip file you will find a class called AnnotatedBeanProxy.java, which allows a developer to place annotations on their java remote objects. The annotations class is called FlexField.java, and allows a developer to place the following restrictions on their getters/setters: ReadWrite, ReadOnly, CreateOnly, Transient, Excluded. Each value is described in more detail in the javadoc, but in summary, the options provide a developer both with flexibility and added security on remote objects.

In the zip file you will find:

1. blazeds-annotations15 project: blazeds\trunk\modules\annotations15
2. BeanProxy.patch, a minor change is needed to the BeanProxy class.
3. One actionscript added under sdk\trunk\frameworks\projects\rpc\src\mx\rpc\remoting
4. Two unitests under blazeds\trunk\modules\core\test\java\flex\messaging\io. (Note, to create unit tests I had to build the blazeds-unittests under java 1.5 without creating another project)

Please consider this enhancement to the blazeds code base.

One thing I forgot to mention: On application startup, you would need to add this line of code to register the AnnotatedBeanProxy:

PropertyProxyRegistry.getRegistry().register(IAnnotatedProxy.class, new AnnotatedBeanProxy());

I have added more documentation for this code here: http://www.flexpasta.com/index.php/2008/05/19/blazeds-with-annotations-for-remote-objects/

Still need to review the code but the approach is solid and this should be pretty easy to incorporate. It would only affect classes which implement the new interface.

from Flex debugger I can see all Excluded or Transient fields and method transfering via network.

@FlexField( fieldType = FlexFieldType.Transient)
@FlexField( fieldType = FlexFieldType.Exclude)

I expect to get fields only what I declared in my AS bean. Now I have to included unexpected fields in my code to avoid
ReferenceError: Error #1056: Cannot create property {FIELD_NAME} on {CLASS_NAME} warnings.

Addition and we include/bind annotation for the public variables in Java code?

Thanks.
David

Or if I will mark setter as private in AS file I will get warning in my console:

ReferenceError: Error #1074: Illegal write to read-only property {FIELD_NAME} on {CLASS_NAME}

If this is a minor enhancement, we could consider this for Beta 2.

FYI,

SpringSource just came up with Annotation-based configuration of remote destinations in their Spring BlazeDS Integration 1.0.0.RC1
cf. http://www.springsource.org/node/1393
