JSON deserialization works from test but not from servlet

Question

I am using the following code to deserialize a JSON object:

System.out.println("Trying to deserialize the following string: " + jsonString);
DRRequest elements = JSONMapper.objectMapper.readValue(jsonString, DRRequest.class);
System.out.println("Done, the resulting object is: " + elements);

When I call the code from the test, it works properly and I get the following output:

Trying to deserialize the following string: { "start_time":"2015-10-19T13:00:00.000+02:00", "interval":900,"unit":"kW","target_values": [50.3253179, 45.15539599955082, 56.13061499595642, 68.14941400289536, 65.17419399321079, 63.140625, 47.14074699580669, 28.16027800738811, 61.14758299291134],"prosumers_primary":[  "Pr_1","Pr_4","Pr_7","Pr_1"],"prosumers_secondary":[  "Pr_2","Pr_3","Pr_8","Pr_11","Pr_16"]}
Done, the resulting object is: com.wattics.vimen.DSSdata.DRRequest@5ae50ce6

But when I try to use the code from the servlet, I get the following error:

Info:   Trying to deserialize the following string: { "start_time":"2015-10-19T13:00:00.000+02:00", "interval":900,"unit":"kW","target_values": [50.3253179, 45.15539599955082, 56.13061499595642, 68.14941400289536, 65.17419399321079, 63.140625, 47.14074699580669, 28.16027800738811, 61.14758299291134],"prosumers_primary":[  "Pr_1","Pr_4","Pr_7","Pr_1"],"prosumers_secondary":[  "Pr_2","Pr_3","Pr_8","Pr_11","Pr_16"]}

Can anyone help me understand what is causing the Exception, how to fix it?

The code of the associated class looks like this:

package com.wattics.vimen.DSSdata;

import org.joda.time.DateTime;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

@JsonIgnoreProperties(ignoreUnknown = true)
public class DRRequest {

  public DateTime start_time;
  public String start_time_text;
  public int interval;
  public String unit;
  public Double[] target_values;
  public String[] prosumers_primary;
  public String[] prosumers_secondary;
  public String type;

}

It seems your `JSONMapper.objectMapper` has a different configuration when run from the test than from the production code — Adam Siemion, Jul 13 '17 at 11:10
@AdamSiemion: where would that configuration be? I have the following config files in the project, and none of seem to have anything related... `src/main/resources/localhostTestConfig.cfg.xml src/main/resources/logback.xml src/main/webapp/WEB-INF/web.xml src/main/java/com/hibernate.cfg.xml` Note that I am trying to run a project that someone else wrote, so I don't have good knowledge of the setup — user000001, Jul 13 '17 at 11:29
@SachinGupta: But how to add it to Glassfish's classpath? I donwloaded `jackson-datatype-joda-2.8.1.jar` and put it in `~GlassFish_Server/glassfish/modules/`, but the error is still the same. But I think that you are right about the dependency, because when I comment the DateTime field from the class, then it doesn't cause any errors. — user000001, Jul 13 '17 at 12:13

It turns out there was something wrong with Glassfish's configuration. I deployed on tomcat8 and works properly.
