I have a dynamic-web project set up on Eclipse and I'm using Tomcat 7 as my web server. It doesn't seem to be automatically putting 3rd party JARs I add to my library on my build path into the WEB-INF/lib folder. Is there a way I can do this automatically? Every time I search for an answer to this, I find something like this.
So how do I do that automatically? Is there a way to configure my build path to do this?
Here are the instructions for Helios. For earlier releases, see SeanA's answer.
- Project Properties -> Deployment Assembly
- Add -> Java Build Path Entries
- You should now see the list of libraries on your build path that you can specify for inclusion into your finished WAR.
- Select the ones you want and hit Finish.
You can use "Ant" to copy files to WEB-INF/lib when you deploy files. Using Ant you will be able to copy only those files which have changed.
I haven't tried this personally, but what I believe it does is what I think you are looking for:
- Right-click project -> Properties
- Go to Java EE Module Dependencies
- Check the boxes for the JARs that you want to export with your Web Application
Let me know if this automatically puts them in your exported WAR. I always just add mine to WEB-INF/lib :)
Instructios for Eclipse Indigo (version 3.7.2)
- Project Properties -> Deployment Assembly
- Add -> Archives From File System -> Next -> Add
- (The file dialog of your system opens up.)
- Navigate to the archive you want to include in your WEB-INF/lib, select it and hit OK.
- Hit Finish.
- Hit OK.
