This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Sometimes you can make a error in deployment descriptor, e.g wrong JNDI name. After Run Project you get message about succesful build and deployment. However, load failed and module is disabled. User don't realize this without watching server.log. Then he can find for example: WEB0123: WebModule [AdminJ2EE:AdminWeb.war] failed to deploy and has been disabled: [javax.naming.InvalidNameException: Real JNDI name cannot be empty for jdbc/OracleDb].|#] I hope that should be useful log server error messages to NetBeans output window.
Enhancement; wont be fixed for 4.1
TM 5.0 -> TBD
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
