tldScanJar warning using Tomcat

I receive a tldScanJar warning using Tomcat. The console of eclipse shows:

org.apache.catalina.startup.TldConfig tldScanJar warning: Failed to process JAR [jar:jndi:/localhost/fileUpload/WEB-INF/lib/commons-io-1.3.2.j开发者_开发技巧ar!/null] for TLD files java.io.IOException: access denied

Any suggestion is welcome

Had this yesterday myself on tomcat 7.0.12, jdk 1.6.0_25 (x64, centos). Turned out to be that removal of the temp directory from the tomcat directory caused this issue. Try adding tomcat/temp and ensuring that the user running tomcat has full control of it. Also, check permissions to the rest of the tomcat directory to be sure that it isn't having an access problem there, either.

I had the same problem, setting "Full" permissions for my user account (RMB on Tomcat dir -> Security -> Edit -> Add, write your login -> Ok, and check "Full control").

In my cases, I was getting the same issue, but I was doing one mistake, I had opened my IDE (I was using IntelliJ) by simply double clicked.

But when I opend my IDE with right-click, and choose Run as Adminstrator then it does not happened in my case. So try it. Please don't ignore any small mistake.

I recently got this error with Tomcat 7.0.21 on Windows 7 when a war contained jars which had duplicate class definitions (a class was defined in more than 1 jar within the war's WEB-INF/lib directory). Cleaning up the jar list solved the problem (tho i didn't go back and try to repro/test it).
