I have an entity at my java backend which has a joda DateTime field called createdAt. I have a post API to update these values on the Database. The post API accepts application/json values.

I have an use case where in i need to make a Ajax POST request from my javascript file that updates the entity with the current date.

Now that i need to pass a DateTime value in the POST data, i face a problem in converting the javascript Date object into joda DateTime.

I have tried sending the javascript Date object but it responds as :

Also Note: I cannot perform any actions on the data i receive from javascript before sending it to the repository on the java side.

A bit late perhaps, but:

I had a similar problem. We use org.joda.time.LocalDate in our backend and passing a new Date() from javascript to the backend resulted in a conversion error. We solved this by using new Date().valueOf() instead. This will get the milliseconds since 1 jan 1970 (read about it at MDNs JavaScript Date page).

After that you could just do org.joda.time.LocalDate.parse(passedInValue)

Objects cannot be "sent" in API calls. Objects are serialized(convert to string in this case) and deserialized(convert to appropriate object from string)

In this case:
- Serialization: Convert the Javascript Date object to appropriate format in a string before making the POST call
- Deserialize: Refer Converting a date string to a DateTime object using Joda Time library to convert the string into a DateTime object.

You can convert JavaScript new Date().toString(),and post the string value to the server, then you can use SimpleDateFormat to convert this value to any date format in java server.
