Using REST via GlassFish server- How do I allow updates on a list using HTML input and return a JSON object?

I am using GlassFish 4.1, using REST services within my web.xml (using JAX-RS,) and running queries on my temporary ObjectDB database. I need the input to by checked and return a JSON object with my desired information.

I have tested the entire program off of the server, and it works perfectly. However, while I am hosting it on the local port 8080 and I enter a valid search entry, when it attempts to add to the list, I get an error:

Warning: StandardWrapperValve[DataSearch2]: Servlet.service() for servlet DataSearch2 threw exception
javax.persistence.PersistenceException: No Persistence provider for EntityManager named $objectdb/db/customerDetails.odb
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:85)

If I run the HTML and submit a search that will return 0 results I DO get a blank JSON file back!

But if I run a valid search that would return actual information, I get the "no persistence" error.

This is happening when I have the driver update its own list. I AM sure that I have the correct .jar in the web.inf folder.

Any idea why this would be happening?

I did find a resource outlining a similar problem in No Persistence provider for EntityManager named, but since it is not the same framework, the answers don't really help me.

Solution

  • The error message indicates that objectdb-jee.jar is missing.
