tomcat 8 in Eclipse Luna 启动失败：目录 [C:\Program Files\Eclipse\eclipse\lib] 出错

Question

I need your help.

I'm new on eclipse. (I have been used Intellij until now)I installed java,tomcat,maven and finished all integrations and configurations.

I created maven project on Eclipse Luna but when I want to debug I get an this error message.

WARNING: Problem with directory [C:\Program Files\Eclipse\eclipse\lib],
exists: [false], isDirectory: [false], canRead:[false]
java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina

at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:465)

Do you know How can I fix this? Thanks.

Answer 1

You need to configure your project as a Dynamic web project or if the project is already created add the faced to it by doing:

Right-click the project --> Properties --> Project Facets --> check the Dynamic Web Module facet --> OK.

Answer 2

I had that same problem and here's how I solved it.

I went to "Run -> Run Configurations" and selected the problematic server under "Apache Tomcat". After that, I selected the "Arguments" tab and changed the working directory from the default to where I had Tomcat installed (for me it was in an opt dir)
