Hi Oliver,
Thanks for your response. Yes, we can use MERGE in a Http URL through Postman,
but I'm writing a java application to modify data. As what I said before,
there's a validate Http method list and Merge/Patch are not in it.
Here's the document I referenced:
h5. [{color:#59afe1}How to use Apache Olingo as Client Library-Update the
data{color}|https://olingo.apache.org/doc/odata2/tutorials/OlingoV2BasicClientSample.html#updatedata]
Unlucky, in this doc, it says "{color:#59afe1}{color:#205081}_MERGE/PATCH_ it
is also possible to send only the _to be updated_ data as _POST Body_ and
omitting the unchanged data. But this is (currently) not shown within this
sample{color}.{color}"
How can I use them ?
Regards,
Wendy

> HTTP method: PATCH
> at java.net.HttpURLConnection.setRequestMethod(HttpURLConnection.java:440
