ORA-01033: ORACLE initialization or shutdown in progress

I am sure you reading this post because you've got this ORA-01033 error message.

 

Quickly without wasting time here is the solution:

I have noticed this error happened when the database has not been properly shutdown .

1. Go to the command prompt CMD:
2. > set oracle_sid= your_sid_name
3. > sqlplus /nolog
4. SQL> connect / as sysdba
5. output: connected
6. SQL> shutdown abort
7. output: ORACLE instance shut down
8. SQL> startup nomount
9. output: ORACLE instance started
10. SQL> alter database mount
11. output: Database altered
12. SQL> alter database open
13. output: Database altered
14.  Done !

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.sun.faces.application.view.StateHolderSaver

I have faced this problem while navigating back and forth in my project
using netbeans 7.1 , glassfish 3+ , primefaces 2.1 and openfaces 3.0;

After some minutes of headache I finally solve by adding <redirect/> under the navigation case in web.xml file:
e.g:

<navigation-rule>
        <from-view-id>/student/SearchEdit.xhtml</from-view-id>
        <navigation-case>
            <from-outcome>back</from-outcome>
            <to-view-id>/student/Search.xhtml</to-view-id>
            <redirect/>
        </navigation-case>
    </navigation-rule>

hope you rock!!!

IP restriction with jsf and glassfish

After completing one of my j2ee application I needed to secure it but how ?
The first idea that came into my mind was to develop my own custom security module. What I did but somewhere along the lines I change my mind for a built-in REALM.

Implementing the built-in security that come with glassfish is straight forward
as you can see from these blogs

3. http://www.greenkode.com/2011/09/user-authentication-and-authorization-using-jaas-and-servlet-3-0-login/ 

Everything  went smoothly I realize there was no simple option in glassfish that could allow me to prevent some ip address  from accessing my application. Even thought we can use virtual server  and certificates to do the job, I found them advanced and difficult .

An easier way to do this will just be to use the following

HttpServletRequest httpServletRequest = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest(); 

String ip = httpServletRequest.getRemoteAddr();

To get the incoming ip and .... rocks!!

I will be back on this topics soon
