> [@prasath.t](#): > > `Caused by: java.lang.ClassNotFoundException: com.inductiveautomation.webbrowser.BrowserComponent` You don't have the web _browser_ module (anymore), but you did at one point in time, because a web browser component is serialized into your window(s). ---

Instead of web browser module now… what is the alternative solution? ---

There is none. You can install it (in trial mode) and delete the component from the windows you have, but this is just the way Vision works - if you’re missing a module that adds a component, the window is locked. ---

Soo we can’t able integrate web based modules in vision? ---

You are _missing a module_ - the [Web Browser Module](https://docs.inductiveautomation.com/display/DOC81/Web+Browser+Module). If you don’t have it, then you can’t use it. If you want to use it, then you need to install it. That’s all this error is telling you. ---
