Answer 1

This error is occuring due to missing tomcat-juli.jar in the Launch environment in Eclipse

I solved it by doing the below steps-

1.Double click on the installed Ode v1.x Server in the 'Server' View.

2.Click on Open launch configuration.

3.Choose Classpath tab > Add External JARs > [your TOMCAT_DIR]\bin\tomcat-juli.jar.

4.Click Apply then OK.

5.Start your Tomcat Server

Answer 2

Please check if your tomcat server has tomcat-juli.jar in $TOMCAT_HOME/lib directory. Looks like it is the problem with tomcat server jar files. Please check your installation for correctness

Note : Please see the error

Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit.

It doesn't even get started. It couldn't find the main class itself
