Handle Connection Exception
Habib Eslami
Member Posts: 419 Bronze Badge
Hi dears,
I use jdev 11.1.1.7.0.
I need to handle the closed connection exception in my project, for this I've created MyErrorHandler class which extends DCErrorHandlerImpl (also updated DataBindings.cpx) and I've override the reportException() method as below :
@Override
public void reportException(DCBindingContainer formBnd, Exception ex) {
String msg = "";
JboException e = null;
Object[] exceptions;
if (ex instanceof java.sql.SQLRecoverableException) {
msg = ex.getMessage();
if (msg.indexOf("Connection") >= 0) {
e = new JboException("errro in connection to database ...");
throw new JboException(e);
} else {
super.reportException(formBnd, ex);
}
} else if (ex instanceof javax.el.ELException) {
msg = ex.getMessage();
if (msg.indexOf("JBO-26061") >= 0) {
e = new JboException("errro in connection to database ...");
throw new JboException(e);
} else {
super.reportException(formBnd, ex);
}
} else if (ex instanceof oracle.jbo.DMLException) {
this.reportException(formBnd, (Exception)ex.getCause());
} else if (ex instanceof oracle.jbo.JboException) {
exceptions = ((JboException)ex).getDetails();
if (exceptions.length > 0) {
for (int i = 0; i < exceptions.length; i++) {
this.reportException(formBnd, (Exception)exceptions[i]);
}
} else {
super.reportException(formBnd, ex);
}
}
}
when the connection is closed(in any reasons) the pop up error shows to user, which is too unclear
Is there any solution to handle this exception and then navigate to Error page or Login page.
Regards,
Habib

As suggested, what does the server log message indicate?

Timo Hahn Senior Principal Technical Consultant - Oracle ACE Director Member, Moderator Posts: 38,585 Red DiamondHave you debugged the error handler?
Make sure the error handler is used and caches the exception from the DB. I guess your hander is not handing the connection loss.

Hi
yes, the error handler caches the exception.
I changed the reportException() to put some logs :
@Override public void reportException(DCBindingContainer formBnd, Exception ex) { String msg = ""; JboException e = null; Object[] exceptions; System.out.println("reportException ..........................................."); System.out.println("excception class : " + ex.getClass()); System.out.println("toString : " + ex.toString()); System.out.println("getMessage : " + ex.getMessage()); if (ex instanceof weblogic.jdbc.extensions.PoolDisabledSQLException) { msg = ex.getMessage(); System.out.println("throw error_1"); e = new JboException("1_error in connection to database ..."); throw new JboException(e); } else if (ex instanceof java.sql.SQLRecoverableException) { msg = ex.getMessage(); if (msg.indexOf("Connection") >= 0) { System.out.println("throw error_2"); e = new JboException("2_error in connection to database ..."); throw new JboException(e); } else { super.reportException(formBnd, ex); } } else if (ex instanceof javax.el.ELException) { msg = ex.getMessage(); if (msg.indexOf("JBO-26061") >= 0) { System.out.println("throw error_3"); e = new JboException("3_error in connection to database ..."); throw new JboException(e); } else { super.reportException(formBnd, ex); } } else if (ex instanceof oracle.jbo.DMLException) { this.reportException(formBnd, (Exception)ex.getCause()); } else if (ex instanceof oracle.jbo.JboException) { exceptions = ((JboException)ex).getDetails(); if (exceptions.length > 0) { for (int i = 0; i < exceptions.length; i++) { this.reportException(formBnd, (Exception)exceptions[i]); } } else { super.reportException(formBnd, ex); } } }and the server logs :

Yes, but you only rethrow the error. Check the old sample for the article 'Catch me if you can' from an old ORacle Magazin https://community.oracle.com/tech/developers/discussion/4494822/exception-handler-for-oracle-adf-application
The article itself is offline currently. You need to change the exception handler of the view layer too.

What is the weblogic server version? A known issue does exist:
Troubleshooting java.sql.SQLException: "Connection has been administratively disabled. Try later" (Doc ID 1211143.1)

Hi
What is the weblogic server version? A known issue does exist:
Troubleshooting java.sql.SQLException: "Connection has been administratively disabled. Try later" (Doc ID 1211143.1)
I use jdev 11.1.1.7.0 and weblogic server 11g 10.3.6.0.
I do myself shutdown the connection in weblogic to check how I can handle the exception.
Regards,
Habib

The known issue is with Oracle WebLogic Server - Version 10.0 to 10.3. A java.sql.SQLRecoverableException is recoverable and not meant to be handled and rethrown other than may be to provide an easier-to-understand and descriptive message.
public class SQLRecoverableException extends SQLException
The subclass of
SQLExceptionthrown in situations where a previously failed operation might be able to succeed if the application performs some recovery steps and retries the entire transaction or in the case of a distributed transaction, the transaction branch. At a minimum, the recovery operation must include closing the current connection and getting a new connection. -
I've added logout() method and called it from reportException()
private void logout() { try { FacesContext fctx = FacesContext.getCurrentInstance(); ExternalContext ectx = fctx.getExternalContext(); HttpServletRequest request = (HttpServletRequest)ectx.getRequest(); HttpServletResponse response = (HttpServletResponse)ectx.getResponse(); response.sendRedirect(request.getContextPath() + request.getServletPath() + "/Login.jspx"); } catch (Exception e) { e.printStackTrace(); } }when this method is called, nothing happens and the control doesn't navigate to login page and still shows the popup error (for closed connection).

Habib

The reportException method does not call the logout() method in sample listed. Please list the call to logout:
else if (ex instanceof java.sql.SQLRecoverableException) { msg = ex.getMessage(); if (msg.indexOf("Connection") >= 0) { System.out.println("throw error_2"); e = new JboException("2_error in connection to database ..."); throw new JboException(e); } else { super.reportException(formBnd, ex); } }Moreover, if logout() is added after some exception messages are output, the logout() may not get called.

Hi
I've added the logou() method into reportException() as follows :
@Override public void reportException(DCBindingContainer formBnd, Exception ex) { String msg = ""; JboException e = null; Object[] exceptions; if (ex instanceof java.sql.SQLRecoverableException) { msg = ex.getMessage(); if (msg.indexOf("Connection") >= 0) { logou(); //e = new JboException("errro in connection to database ..."); //throw new JboException(e); } else { super.reportException(formBnd, ex); } } else if (ex instanceof javax.el.ELException) { msg = ex.getMessage(); if (msg.indexOf("JBO-26061") >= 0) { logou(); //e = new JboException("errro in connection to database ..."); //throw new JboException(e); } else { super.reportException(formBnd, ex); } } else if (ex instanceof oracle.jbo.DMLException) { this.reportException(formBnd, (Exception)ex.getCause()); } else if (ex instanceof oracle.jbo.JboException) { exceptions = ((JboException)ex).getDetails(); if (exceptions.length > 0) { for (int i = 0; i < exceptions.length; i++) { this.reportException(formBnd, (Exception)exceptions[i]); } } else { super.reportException(formBnd, ex); } } }Regards,
Habib
