**Kibana version** :6.5.4

**Elasticsearch version** : 6.5.4

**APM Server version** :6.5.4

**APM Agent language and version** :6.5.4

**Browser version** :

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**:

**Fresh install or upgraded from other version?** Fresh

**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:  
I am trying out a simple program to understand the usage of the APIs.  
I can see the transaction in Kibana APM, but could not get the information related to span

//Code

ElasticApmAttacher.attach();

```
    Transaction transaction = ElasticApm.startTransaction();
    try {
        transaction.setName("transactionName");
       //Do Something

        Span span = ElasticApm.currentSpan().startSpan();
        try (final Scope scope = span.activate()) {
            span.setName("customSpan");
            //Do Something

        } catch (Exception e) {
            span.captureException(e);
            throw e;
        } finally {
            span.end();
        }
    } catch (Exception e) {
        transaction.captureException(e);
    } finally {
        transaction.end();
    }

```

**Errors in browser console (if relevant)**:  
In [http://localhost:8200/intake/v2/events](http://localhost:8200/intake/v2/events) i get this error  
{"accepted":0,"errors":[{"message":"only POST requests are supported"}]}

Hi and welcome to the forum!  
Since you only created a transaction without [activating](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-span-activate) it, you cannot get it through [`currentSpan()`](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-current-span) (see notes in documentation), so you are not creating a child span as you expect.  
I hope this helps.
