Java.io.FileNotFoundException: C: \ Program Files \ Apache Software Foundation \ Tomcat 7.0 \ logs \ localhost_access_log.2012-07-12-12.txt (Access denied)

Question

I am trying to test my servlet by running it on Tomcat. However, I get the above error (sometimes this error occurs, but before the servlet worked fine). A few facts:

• I examined in detail the explanations for this similar problem , as well as here and here

• When I try to restart Tomcat (from the Eclipse Servers tab), I get an error from the console:

"SEVERE: Could not open the access log file [~ \ Tomcat 7.0 \ logs \ localhost_access_log.2012-07-12.txt]" and at the very end of the log output, there is "INFO: SessionListener: sessionDestroyed ('E9A6117FDF54752D80A1B9B72F2B83D3') - for more details, see At the bottom of this text.

3. I looked at my log files in the folder "C: \ Program Files \ Apache Software Foundation \ Tomcat 7.0 \ logs" and there is no file with contents similar to that contained in paragraph (2) above

4. "Deploying" my application through Eclipse (that is, during development, I rely on Eclipse to run Tomcat), only doing a real deployment when I have a stable version of my project, copying the corresponding java class files to the Tomcat / webapps / WEB- folder INF / classes and restarting Tomcat

and, most importantly, 5. Entering into " http: // localhost: 8080 " takes me to the Tomcat homepage (so I'm sure the server is working), whereas " http: // localhost: 8080 / MyProjectName / MyServlet " in the browser results in the error indicated in this question header.

Any ideas / help? Thank you very much!

Answer 1

performs only real deployment when I have a stable version of my project by copying the appropriate Java class files to the Tomcat / webapps / WEB-INF / classes folder and restarting Tomcat

Stop right there: you should never put files in webapps/WEB-INF and expect anything good. Deploy your webapp correctly using well-accepted packaging, such as a WAR file or exploded WAR structure, into the webapps directory.

Secondly, the problem is obvious: java.io.FileNotFoundException: C:\Program Files\Apache Software Foundation\Tomcat 7.0\logs\localhost_access_log.2012-07-12.txt (Access is denied) . Your Tomcat cannot write to this file. Just because you are an administrator does not mean that Tomcat can write to this directory: Tomcat does not work very well with UAC, as far as I know, and you are trying to write to Program Files , which usually requires some ugly user interface credentials to crack .

So, check the permissions on the file (and directory). Check the uid of the Tomcat process: make sure they are all good. Finally, consider using CATALINA_HOME and CATALINA_BASE (read the documentation on how to do this) to fix all your permission problems.
