If you need to embed a necessary bundle for your URCap plugin, please refer to the [Apache Felix Maven Bundle Plugin](http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html). The bundle must be “embedded” inside the .urcap file, which essentially is a .jar file. Please check your `pom.xml` file for the `` tag, and embed the bundle through here. You can check is the dependency is a success, by checking the .jar file after build for the referenced dependency. Besides from embedding the necessary classes, OSGi will also expect `MANIFEST.mf` to include the correct Export-Package packages. However if the dependency already is a valid OSGi-bundle, this will happen automatically. Please note, that since the URCap API uses generic OSGi, you should check out relevant Maven and OSGi manuals for further documentation. ---

Hello, I was able to embed the bundle in a urcap. I validated that the bundle is working with the Remote Shell. But the embedded bundle was not loaded automatically. Specifically, here is what I did on the Remove Shell: - -\> ps # my embedded bundle is not listed - -\> install file:///opt/usrim/[path-to-bundle]bundle.jar - -\> ps # my bundle is in the installed state - -\> start [my-bundle-id] - -\> ps # by bundle is in the Active state, The Activator is executed. My question is, how can I automatically load and start my embedded bundle? Thanks. Pierre ---

@anon93510157 It seems you have not embedded the dependency in your URCap? But just has a bundle placed somewhere in the controller? You should embed the dependency using `` tag, so you have exactly one bundle, which would be your .urcap file. If you have issues making this work, please upload your `pom.xml` file so I might investigate it. ---

I want to be sure that I did not misunderstand your original post. This tag can be used to embed an additional OSGi bundle in my URCap? Is that right? So if I emded an additional bundle I should expect its Activator to be executed in addition to the URCap’s Activator. Is that right? To answer your questions, I’m pretty sure I did use the tag since I can see my embedded bundle in the folder bundle.jar-embedded in the felix-cache. Here are my two pom.xml. The first one is the urcap. The second one is the OSGi addition bundle. > **[Google Drive: Sign-in](https://accounts.google.com/v3/signin/identifier?dsh=S-888350322%3A1673731547880123&continue=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F0B9H6mDcCLW2oLUh4MVVWZ0U5ajg%2Fview%3Fusp%3Dsharing&followup=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F0B9H6mDcCLW2oLUh4MVVWZ0U5ajg%2Fview%3Fusp%3Dsharing&passive=1209600&service=wise&flowName=WebLiteSignIn&flowEntry=ServiceLogin&ifkv=AeAAQh6N90IME77xW-_MfwAg-QWzTF5-2NRhcgAJ7aq1iwn2Mp_E3-TmkhKJf8DhBc-GuW4_vCLmBQ)** > > Access Google Drive with a Google account (for personal use) or Google Workspace account (for business use). > **[Google Drive: Sign-in](https://accounts.google.com/v3/signin/identifier?dsh=S-1693526932%3A1673731548975704&continue=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F0B9H6mDcCLW2oNDg3LWpYUWZTeFE%2Fview%3Fusp%3Dsharing&followup=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F0B9H6mDcCLW2oNDg3LWpYUWZTeFE%2Fview%3Fusp%3Dsharing&passive=1209600&service=wise&flowName=WebLiteSignIn&flowEntry=ServiceLogin&ifkv=AeAAQh4J-mHqTOE2ghiXxlq0mgnGw8KaIrqrOnMBdSKtwc-rxpc_MfSWRr8XJzJblFveD3QpcTACew)** > > Access Google Drive with a Google account (for personal use) or Google Workspace account (for business use). ---

@jbm Can you take a look at my previous post. Thanks. ---

Hi, i faced a related issue today as i tried to use third-party jars and update their version with a urcap remote update. It seems that the embedded jars are not updated until their zombie copies in the felix-cache folder are dropped and replaced by the updated embedded jar from the urcap update. Is there a way to clear these embedded jars in the felix cache folder on deployment? ---

Hi, i found out that using **mvn clean install** instead **mvn install** solves the cache issue. It’s more likely a build lifecycle issue than a cache problem 😉
