You may run into this issue when you try to compile your JSP project:
Target runtime Apache Tomcat v7.0 is not defined
Faceted Project Problem
Make sure to install correct Apache Tomcat version. For the easiest installation, you can download and run “32-bit/64-bit Windows Service Installer” for any version (In my case, it is Tomcat 8.0.37).
After installing Apache Tomcat, follow the steps below.
- Install JST Server Adapters (Help -> Eclipse Marketplace)
- Right click on your project. Choose “Properties“
- Go to “Targeted Runtime“
- Choose or Add the Tomcat version you prefer
If this doesn’t solve the issue, try changing the target runtime in the configuration file (org.eclipse.wst.common.project.facet.core.xml).
