Tomcat 7 e Windows 7: impossibile accedere all’area Manager

Se dopo aver installato Tomcat 7 su Windows 7 non avete accesso all’area Manager di Tomcat tramite browser, per via di permessi mancanti, occorre modificare manualmente il file tomcat-user.xml.
Il file presente nella cartella conf dell’installazione di Tomcat può contenere la definizione:

<user name="admin" password="admin" roles="admin,manager" />

che consente nelle versioni precedenti di accedere all’area manager, specificando fra i ruoli anche manager, ma che non è corretta per la versione 7. In questo caso la dicitura deve essere:

<user name="admin" password="admin" 
     roles="admin,manager-gui,manager-script,manager-jmx,manager-status" />

I quattro nuovi ruoli vengono specificati anche nella pagina di errore che viene restituita nel momento in cui ci viene vietato l’accesso.

Questo è un file tomcat-user.xml standard corretto:

<?xml version='1.0' encoding='cp1252'?>
