Hi, we wrote a small application with some beans (cmp, stateful, stateless) and some JSP's. The beans and the webapp are in the same security domain behind a form based login and the DatabaseServerLoginModule. After successful login (principal = name) and getting some JSP-stuff, the first access to a ejb from another ejb throws a SecurityException. The server had lost the principal (principal = null). What's wrong ? Our config: JBoss 2.4.0.26 with Tomcat 3.2.3 Windows 2000 Oracle 8 the log: [JBossSecurityMgrRealm] Authenticating access, username: alxs R( /foo + /control + /sec/signin) [JBossSecurityMgrRealm] ClassLoader: AdaptiveClassLoader( ):250746 [JBossSecurityMgrRealm] Servlet ClassLoader: AdaptiveClassLoader( ):1419599 ...
