I used WSO2 EI 6.4.0.
I need to write a custom mediator used an external jar, called JAVA_SDK_VXP-2.0.3.jar (com.vpcp.services package).

package com.quangnam.example;



import org.apache.synapse.MessageContext; 

import org.apache.synapse.mediators.AbstractMediator;



import com.vpcp.services.AgencyServiceImp;

import com.vpcp.services.model.GetAgenciesResult;



public class AgenciesListMediator extends AbstractMediator { 



    public boolean mediate(MessageContext context) { 

        getAgenciesList(context);

        return true;

    }



    private void getAgenciesList(MessageContext context) {

        AgencyServiceImp agencyService = new AgencyServiceImp();

        String jsonHeader = "{}";

        GetAgenciesResult getAgenciesResult = agencyService.getAgenciesList(jsonHeader);        

        context.setProperty("agenciesResult", getAgenciesResult.getAgencies());

    }

}

The JAVA_SDK_VXP-2.0.3.jar needs to call httpclient-4.5.6.jar. I have a jar as httpclient_4.3.6.wso2v2.jar in {EI-HOME}/wso2/components/plugins. This jar comes with WSO2 EI.

I deployed custom mediator and copy httpclient-4.5.6.jar, JAVA_SDK_VXP-2.0.3.jar to {EI-HOME}/lib folder.
Everything is OK, but when I called the API used the custom mediator, there is an exception:

I started EI server with -DosgiConsole. As the result, I think the JAVA_SDK_VXP-2.0.3.jar called httpclient_4.3.6.wso2v2 not httpclient-4.5.6.jar, so there is no method setValidateAfterInactivity()

But nothing has changed. Please help me.

I updated the pom.xml with Embed-Dependency tag but still error

UPDATE

I resolved it. After editing MANIFEST.MF, from {EI-HOME}/lib, I deleted httpclient-4.5.6.jar, JAVA_SDK_VXP-2.0.3.jar and restart EI server.
