Hi guys,
Is it possible for me to add an array of objects to the data service? I
have looked at the possibility of Batch queries (
https://github.com/wso2/product-dss/blob/master/modules/samples/dbs/rdbms/BatchRequestSample.dbs
and docs - https://docs.wso2.com/display/DSS350/JSON+Mapping+Sample)
When I am sending in the request like below -
{ "_post_r_batch_req": {
"_post_r": [
{
"added_by": "d",
"end_date": "2016-03-14T00:00:00+05:30",
"start_date": "2016-07-16T00:00:00+05:30",
"status": "a",
"type": "a",
"email": "b...@b.com"
}, {
"added_by": "d",
"end_date": "2016-03-14T00:00:00+05:30",
"start_date": "2016-07-16T00:00:00+05:30",
"status": "a",
"type": "a",
"email": "c...@c.com"
}
]
}
}
I am getting the below exception. Any ideas?
08:48:58,912 org.apache.catalina.core.StandardWrapperValve -
