WSO2 Micro Integrator 1.2.0 call data service over local transport

I have a Proxy Service which calls Data Service. I want to call Data Service over local transport but I got an error:

[2020-12-19 23:48:59,567] ERROR {ClientUtils} - The system cannot infer the transport information from the local:///services/test/ URL.

My Sequence is

<?xml version="1.0" encoding="UTF-8"?>
<proxy name="TST2" startOnLoad="true" transports="http https" xmlns="http://ws.apache.org/ns/synapse">
    <target>
        <inSequence>
            <payloadFactory media-type="xml">
                <format>
                    <soapenv:Envelope
                        xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                        xmlns:test="test-ns">
                        <soapenv:Header />
                        <soapenv:Body>
                            <test:_get_test_getcnt />
                        </soapenv:Body>
                    </soapenv:Envelope>
                </format>
            </payloadFactory>
            <header name="soapAction" scope="transport" value="urn:_get_test_getcnt"></header>
            <send>
                <endpoint>
                    <address uri="local:///services/test/" format="soap11"/>
                </endpoint>
            </send>
        </inSequence>
        <outSequence>
            <log level="full" />
            <respond />
        </outSequence>
        <faultSequence>
            <log level="full" />
        </faultSequence>
    </target>
    <publishWSDL key="wsdl"></publishWSDL>
</proxy>

Data serivce have allowed local transport:

<data transports="http local https" serviceNamespace="test-ns" name="test">

If I change the endpoint address uri to HTTP transport http://localhost:8290/services/test/ everything works fine. Am I doing something wrong or local transport is not supported in WSO2 Micro Integrator 1.2.0?

The answer is different for each version of the Enterprise Integrator.

For version 6.x.x

You can use this manual: https://docs.wso2.com/display/EI650/Local+Transport

For version 7.x.x

Unfortunately version 7.x.x is very poorly documented in many parts including this one.

Solution

Add the following section to your conf/deployment.toml

[transport.local.sender.nonblocking]
enable = true

Note

In the older solutions it was also necessary to replace ServerURL property for

<ServerURL>https://${carbon.local.ip}:${carbon.management.port}${carbon.context}/services/</ServerURL>

However, my EI´s local transport worked even without this change

Why does it work

As in the previous version, what is needed to be done is add the following row manually to conf/axis2/axis2.xml

<transportSender name="local" class="org.apache.axis2.transport.local.NonBlockingLocalTransportSender"/>

Unfortunately, that won´t work as your file will get replaced with a new one without your changes in it once the enterprise integrator starts. Your axis2.xml is being replaced by a generated jinja2 template from location repository/resources/conf/templates/conf/axis2/axis2.xml.j2

You can notice that there is this piece of code inside:

{% if transport.local.sender.nonblocking.enable == true %}
    <transportSender name="local" class="org.apache.axis2.transport.local.NonBlockingLocalTransportSender"/>
{% endif %}

Which means all you need to do is to add property transport.local.sender.nonblocking.enable and set it to true

Did you enable the local transport in MI as mentioned in [1].
