title: How to run "hello world" JSP page with Tomcat8 in Intellij IDEA 15?
body: <p>I created webproject template in Intellij IDEA 15 (EE) and tried to run "hello world" application with simple JSP page on installed Tomcat server. But I've got this kind of error:</p>
  
  <pre><code>Error running Tomcat 8.0.33: Error copying configuration files from /opt/tomcat/conf to /home/praytic/.IntelliJIdea15/system/tomcat/Tomcat_8_0_33_webproject/conf: /opt/tomcat/conf/catalina.properties (Permission denied)
  </code></pre>
  
  <p>I tried <a href="https://stackoverflow.com/questions/16428126/intellij-needs-to-copy-tomcat-conf-directory-to-project-directory">this</a> answer, but it didn't make a thing. I don't know, maybe the reason is that I use wrong installation guide. However it works fine from the terminal. <a href="https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-14-04" rel="nofollow noreferrer">How To Install Apache Tomcat 8 on Ubuntu 14.04</a></p>
  
  <p>I've checked the <code>/opt/tomcat/conf</code> permissions and it says that only root has access to <code>list, create/delete</code> the folder and tomcat and me can only list files. However I added myself as a tomcat-user in <code>tomcat-users.xml</code>. Doesn't it matter?</p>
