Hi, A single property-placeholder is only going to allow one backing persistent-id. You can instead create multiple property-placeholders with different ids, e.g. <cm:property-placeholder id="propertiesBean" persistent-id=">. . . <cm:property-placeholder id="edigrid.cluster" persistent-id=" >. . .
see https://stackoverflow.com/questions/50354932/how-to-use-multiple-property-placeholder-in-jboss-fuse-blueprint Hope that helps. -John On Thu, Sep 16, 2021 at 7:58 AM Andrei Petru Mura <mapand...@gmail.com> wrote: > Hi all, > > I'm trying to migrate my camel routes from an older karaf using Spring-DM > to a newer one using Blueprint.
