The error shows up when tomcat is trying to reload the web application.

Description John Holman 2009-01-31 14:45:16 UTC Created attachment 23212 [details] Simple war file illustrating error reading tld the problem I have a web application running in Tomcat 5.5.27 with JDK 1.5.0_16-b02 on Windows XP SP3. log4j-1.2.15.jar and commons-logging-1.1.1.jar are installed in WEB-INF/lib and there is a context.xml file in META-INF. When packaged as a war file this combination reliably produces the exception shown below in the Tomcat console under the following circumstances: 1. deploy the war file (e.g. using Tomcat HTTP manager) 2. stop and restart tomcat 3. undeploy the war file 4. deploy the war file Note that to demonstrate this it is necessary to have both a context.xml file in META-INF and commons-logging-1.1.1.jar in WEB-INF/lib. Also, the problem disappears if you downgrade to commons-logging-1.0.4. Otherwise the contents of the application don't seem to matter, and can be demonstrated in an application containing no classes or other libraries. The only other thing I've found to have an effect is the *name* of the application. "commons-logging-test" exhibits the problem, but in at least one test renaming the same application to start with a letter later in the
