Re: [WebMacro-user] Tomcat can't unload webmacro... logging issue?

[Lane S. <la...@op...>]

The only idea I have at this time is to remove the WebMacro.properties=20
file from the war file and place it in your servlet classpath like=20
classes/ and see if this happens. Perhaps, a file open to a war file???
