I’ve tried many options related to this error. It’s been almost 4 days and I can’t figure out why this is still showing.
I reinstalled tomcat, eclipse and my whole OS 😂.
Hope somebody has a quick fix.
It’s because of some missing jars. Make sure that these jars exist in your classpath.
For adding these jars,
- Open the Server tab
- Double click on the Tomcat6 entry.
- Then click on the ‘Open launch configuration’
- select the Classpath and “Add external jar”
