Can not start the DB Console error

By W.ZH  Aug 21 2009

Issue: On windows, when u try to start the DB EM console, it can not be accessed. go the windows services, we found that only the console service can not start, DB and listener service all start OK. So you DB can only access from SQL plus, can not manage from Web UI.

Go the cmd of windows, start the service (OracleDBConsoleorcl) by command, such as  D:\product\DataBase_10.2.0\bin\nmesrvc.exe

you get error of  “StartServiceCtrlDispatcher failed with err 1063”

Solve: This is because the host name and network problem. go to your host file. define your IP address to map to your machine name.  This also can be the window virtual networking address (not then you can try to start the service again. It works, and you can access EM from web UI again.

check your listener runs or not. If your listener is not running and you need to start it using the "lsnrctl start" command.

Then u can start the console by this :

emctl start dbconsole

emca -config dbcontrol db -repos recreate

Or two steps:

emca -deconfig dbcontrol db -repos drop

JSF message bundle VS Resource Bundle

By W.ZH Aug 04 2009Message Bundle +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Message Bundle in fact is the way before JSF 1.2.

As for localization, JSF allows you to specify a resource bundle in your faces-config.xml file. This will allow JSF to load the appropriate message bundles defined by the users browser. You still have to include it with loadBundle if you want to access it via JSP. JSF also allows you to mess with these resource bundles programatically. Here’s an example of the entry in your faces-config.xml file.


This will tell JSF that is the en (English) locale and to load this by default but it also tells JSF that you have a file that supports the German language which would be specified by the browser.

Loading it into your JSP.

    <f:loadBundle basename="com.facesite.resource.MessageResources" var="msg"/>
The file is in the standard java.util.Properties format.  If you want to access the msg from the backing bean, use this code:

String bundleName = getFacesContext().getApplication().getMessageBundle();
Locale locale = facesContext.getApplication().getDefaultLocale();
ResourceBundle bundle = ResourceBundle.getBundle (bundleName, locale);
String msg = bundle.getString(“your key here”);

normally there is a function in the can do this kind of thing.

Resource Bundle +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

But from JSF 1.2, you have simple way to access the msg. You just need to define the bundle in the resource-bundle tag, then you can directly access from JSF page.  Sth like this:


Of coz in the backing bean,
getFacesContext().getApplication().getMessageBundle() will get null if you only use resource-bundle tag.

And i guess in the backing bean, you can use the
getFacesContext().getApplication().getResourceBundle( xxx,xxx);  to access the msg.
