Unable to get vApp after Compose vApp failing from Java SDK

Hi All,

I have this code that composes Vapp. Once the Vapp is created, it tries to power on the vApp. I was not able to find the vApp, it

        Vdc vdc2Use = main.findVdc("VDC02");
        ReferenceType orgNetworkToUseRef = main.getOrgNetworkMatchingVdc(vdc2Use);
        ReferenceType vAppTemplateRef = main.findVappTemplateRef("myCatalog", "mytemplate");
        main.composeVapp(vAppTemplateRef, vdc2Use, orgNetworkToUseRef);

        System.out.println("Total number of vApps:"+vdc2Use.getVappRefs().size());
     
       
        for(ReferenceType vappRef : vdc2Use.getVappRefs()){
            System.out.println("Vapp: " + vappRef.getName());
            main.powerOnVapp(vappRef);
            //main.deleteVapp(vappRef);
        }

What I am finding is that, the vApp is getting created, but the vdc2Use.getVappRefs().size() is returning me 0.

Can somone help me understand this.

Thanks..
