Hello,
I'm attempting to use the Jersey client (1.1.4.1) and invoke the delete
(java.lang.Class<T> c, java.lang.Object requestEntity) method because
I'd like to specify the resource to be deleted via its representation.
The API for WebResouce seems to allow this - but I am unable to get this
working, I get a null ptr in the client code before it communicates to
the server. I've downloaded the source and attempted to understand why
this is happening, but to no luck. So, I'd appreciate some guidance on this.
- Is this just a stupid thing to do? A misguided way to use REST?
- I'm not using the API correctly in some way?
- ??
Thanks in advance -
Rick
