You can load specific dat files using PDetsFromPath(). And you can switch between different products (that is, your main app, a plugin, etc.) using the SetCurrentProduct() function.
Does that make sense? If not, I can go into the details.
Is it necessary to keep binaries and dat file w.r.t jar file
randomGuyOur product has a plugin which in turn have a key. So we need to check keys of both application and plugin. If i have to load all necessary binaries at first and then to switch between the products, it is not possible because wrt jar both .dat files(of plugin and product ) need to be in same folder.
