How to make a hot deployment of a shared library in Weblogic?

Question

My application AdfWeb.war is deployed at Weblogic 10.3.6.0. It is using one shared library my.shared.lib.jar which is modified very often. The server is running in a development mode.

Every time when I try to deploy new version of the library using option "Deploy to Application Server", I am getting the following error:

[05:43:49 PM] [Deployer:149034] An exception occurred for task [Deployer:149117] deploy library my.shared.lib [LibSpecVersion=7.1.0,LibImplVersion=1.0.0] on ADFServer.: Cannot undeploy library Extension-Name: my.shared.lib, Specification-Version: 7.1, Implementation-Version: 1.0.0 from server ADFServer, because the following deployed applications reference it: AdfWeb.war. [05:43:49 PM] #### Deployment incomplete. #### [05:43:49 PM] Remote deployment failed (oracle.jdevimpl.deploy.common.Jsr88RemoteDeployer)

The application is based on ADF. I am using JDeveloper 11.1.1.7. How to make a hot deployment of a shared library in Weblogic? Now I always have to stop an application, which takes a lot of time.

You can't make a Hot Re-Deployment of a Shared Library which is being used by an application without restarting the application or the server.

I thought this guy was getting to it by playing with the library versions (this might interest you):

There are already two versions of our ADF shared library deployed. Because main site doesn't specify, which version of shared library to use, the latest one will be always used automatically.

Because we are using shared library deployment, there is no need to redeploy main site

But then at the end he confirms what i said:

We need to reload main site in order to use latest available shared library. Otherwise we would need to restart WLS server in order to pick up latest redamurai.shared.lib library updates
