How to catch exception occured into handleLifecycle

Hi,
I need to catch an exception occurred into the handleLifecycle to display a message to user.
The exception is RowInconsistentException occurred when a record is locked by other user.
I tried to catch the exception into handleLifecycle method by override it but it's not working.
Any help?
Thank you

Jamil,
handleLifecycle delegate to the StrutsPageLifecycle class which contains multiple phases (prepareModel, processUpdateModel, ...). You would typically handle the exception around the specific phase which is throwing it by extending the DataAction and overiding the method corresponding to the phase.
The default behavior that you can look at in oracle.adf.controller.lifecycle.PageLifecycle (superclass of StrutsPageLifecycle) is to catch the exception and call a method on the Lifecycle named reportErrors. The implementation of reportErrors for Struts is to collect the tree of error thrown by the model and build a Struts error list that will be displayed in the page using the Struts error tag.
If you prefer to handle the exception differently, the customization should be done in the reportErrors phase.
Errors thrown before the handleLifecycle method are critical and simply thrown back to the Struts framework and can be handle by using the Struts exception to action mapping.

How to catch exception into a String variable ?

I have a code
catch(Exception e)
            e.printStackTrace();
            logger.error("\n Exception in method Process"+e.getMessage());
        }when i open log i find
Exception in method Process null.
But i get a long error message in the server console !! I think thats coming from e.printStackTrace().
can i get the error message from e.printStackTrace() into a String variable ?
I want the first line of that big stacktrace in a String variable.
How ?

A trick is to issue e.printStackTrace() against a memory-based output object.
void      printStackTrace(PrintStream s)
         // Prints this throwable and its backtrace to the specified print stream.
void      printStackTrace(PrintWriter s)
//          Prints this throwable and its backtrace to the specified print writer.Edited by: BIJ001 on Oct 5, 2007 8:54 AM

You want this method System to throw an exception if the String[] is empty?
public void system( ObjectOutputStream output, String cmd [] ) {
if (cmd.length == 0)
throw new IllegalArgumentException("Hey! This is an empty array!");
//...rest of your method
}You can choose for yourself which exception type is most appropriate. You can in theory always use the base Exception but is not very specific nor recommended. In this case, I think an existing unchecked exception such as IllegalArgumentException would be the most appropriate.

How to write exception information into a txt file??

i got a program which generate lots of exception information. its hard to see from the screen, is there any way to make the input into some txt file?
when i use
try
}catch(Exception ex)
// to do something here and make the output into a txt file?
}

depending upon the version of jdk being used one of the options will be to fetch the StackTraceElement array and writing each of the element using the standard file io operation
            StackTraceElement[] elements = ex.getStackTrace();
            int noOfElements = elements.length;
            for (int i=0; i<noOfElements;i++)
                  //fetch the stacktrace element and write to a file.
            }Thanks

How to catch exception while validating the username and password in hbm

Hi,
I do want to set the username and password dynamically in hibernate.cfg.xml
Here below is my configuration file.
{code<hibernate-configuration>
<session-factory>
       <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
       <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

       <property name="current_session_context_class">thread</property>
       <property name="show_sql">true</property>
     </session-factory>
</hibernate-configuration>{code}
Also im getting that session factory object like the below code.
public class Sessions {        private static SessionFactory sessionFactory;      private static Configuration configuration = new Configuration();        static {          try {              String userName = GuigenserviceImpl.userName;              String password = GuigenserviceImpl.password;              String hostName = GuigenserviceImpl.hostName;              String portNo = GuigenserviceImpl.portNo;              String sId = GuigenserviceImpl.sId;                  configuration                      .setProperty("hibernate.connection.username", userName);              configuration                      .setProperty("hibernate.connection.password", password);              configuration.setProperty("hibernate.connection.url",                      "jdbc:oracle:thin:@" + hostName + ":" + portNo + ":" + sId);                try {              configuration.configure("/hibernate.cfg.xml");              sessionFactory = configuration.buildSessionFactory();              GuigenserviceImpl.strAccpted = "true";              }              catch (Exception e) {                    e.printStackTrace();                  GuigenserviceImpl.strAccpted = "false";              }            }          catch (HibernateException hibernateException) {              GuigenserviceImpl.strAccpted = "false";              hibernateException.printStackTrace();          }          catch (Throwable ex) {                GuigenserviceImpl.strAccpted = "false";              ex.printStackTrace();              throw new ExceptionInInitializerError(ex);          }      }          public static SessionFactory getSessionFactory() {          return sessionFactory;      }
So, in this above scenario, suppose if im giving the wrong password means exception should be caught and the string variable "GuigenserviceImpl.strAccpted" should be assigned to false.
But im getting the SQL Exception only in console like wrong username and password. And finally i couldn't able to catch the exception in Sessions class, static block.
Anyone can help me in catching that SQL Exception in my Sessions class and i need to handle that SQL Exception in my class.
Im getting this following exception message in my console.

Hi,
Myself hardcoded that username and password checking like the below code.
String name = loginData.get("userName").toString();
          String pswd = loginData.get("pswd").toString();
          String hstName = loginData.get("hName").toString();
          String prtNo = loginData.get("portNo").toString();
          String sid = loginData.get("sId").toString();
          SessionFactory sessionFactory = null;
          try {
               if (name.trim().equals(userName) && pswd.trim().equals(password)
                         && hstName.trim().equals(hostName)
                         && prtNo.trim().equals(portNo) && sid.trim().equals(sId)) {
                    sessionFactory = Sessions.getSessionFactory();
                    strAccpted = "true";

          } catch (Exception e) {
               e.printStackTrace();
               strAccpted = "false";
          }I have my own values in string objects, then comparing that values with the values from login form. If both values are matching, then i will do configurations in hibernate.
ResourceBundle resourceBundle = ResourceBundle
               .getBundle("com.beyon.ezygui.server.Queries");
     public static final String connection_url = resourceBundle
               .getString("connection.url");
     public static final String userName = resourceBundle.getString("userName");
     public static final String password = resourceBundle.getString("password");
     public static final String hostName = resourceBundle.getString("hostName");
     public static final String portNo = resourceBundle.getString("portNo");
     public static final String sId = resourceBundle.getString("sId");The above are the String objects i'm checking for the match with values from login form.

termination?I suspect that would be a really bad idea. That particular signal very likely indicates that you have corrupted memory. Continuing is unlikely to work.
2. What is 0xC6 in:
As a guess it is an offset into the compiled code which indicates where the memory problem was detected.
That it unlikely to help you with a pointer/memory problem because that is where it was detected and not where it happened. By comparing the source you might be able to determine what was bad and then trace it back.

How to catch Exception in a JSP

Hi there,
I'm building my first JSP application. I still don't know what happens to an exception thrown inside a scrptlet in a JSP page.
My JSP page is resultados.jsp (it processes a DB query):
<%@ page contentType="text/html; charset=iso-8859-1" language="java"
import="java.lang.*,java.sql.*,pcliente.*" errorPage="error.jsp" session="true" %>
<html>
<head>
<title>PCliente - Hist?rico de Mainframe</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body background="imagens/sm_bg.gif">
<TABLE border=0 cellPadding=0 cellSpacing=0>
<TR>
<TD width=5><IMG alt="" height=1 src="imagens/pixel.gif" width=5></TD>
<TD vAlign=top width=125><jsp:include page="menu.jsp" flush="true" /> </TD>
<TD width=25><IMG alt="" height=1 src="imagens/pixel.gif" width=25></TD>
<TD vAlign=top width=365>
<%
try
PCliente pcliente = new PCliente(request.getParameter("maquina"),
                    request.getParameter("acessorio"),
                    request.getParameter("contrato"),
                    request.getParameter("estabelecimento"),
                    request.getParameter("ifiscal"));
ResultSet rs = pcliente.executarQuery();
while (rs.next())
out.println("<BR>" + rs.getString("nome_estab_instalacao"));
out.print(" -----" + rs.getString("num_serie_equipamento"));
out.print(" -----" + rs.getString("num_contrato"));
/*** SQL exception is thrown by pcliente.executarQuery() ***/
catch (SQLException sqlEx)
out.println("<P>" + "There was an error doing the query:");
out.println ("<PRE>" + sqlEx + "</PRE> \n <P>");
application.log("Exception lan?ada", sqlEx);
throw new Exception(sqlEx.toString());
finally
out.println("<P>" + "FINALLY !!!");
%>
</TD>
</TR>
</TABLE>
</body>
</html>
The error.jsp is
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*,pcliente.*" isErrorPage="true" session="true" %>
<html>
<head>
<title>PCliente - Hist?rico de Mainframe - Erro</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<strong>Pagina de Erro</strong>
</body>
</html>
The java class I'm using in this JSP is pcliente/PCliente with the source code:
package pcliente;
import java.sql.*;
public class PCliente
private String numSerieMaquina, numSerieAcessorio, numContrato, numEstabelecimento, ifiscal;
private String strQuery;
private Connection conn;
private ResultSet rs;
private Statement stmt;
public PCliente(String numSerieMaquina, String numSerieAcessorio,
                    String numContrato, String numEstabelecimento,
                    String ifiscal)
conn = null;
rs = null;
stmt = null;
this.numSerieMaquina = numSerieMaquina;
this.numSerieAcessorio = numSerieAcessorio;
this.numContrato = numContrato;
this.numEstabelecimento = numEstabelecimento;
this.ifiscal = ifiscal;
construirQuery();
public ResultSet executarQuery() throws SQLException
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
/* This causes SQLException as a 'c' was taken from oracle in
"jdbc:orale:oci8:@PROD" */
conn = DriverManager.getConnection("jdbc:orale:oci8:@PROD","histmain", "histmain");
stmt = conn.createStatement();
rs = stmt.executeQuery(strQuery);
return rs;
private void construirQuery()
strQuery = "SELECT num_serie_equipamento, num_contrato,
nome_estab_instalacao" +
     " FROM anmpf04" +
     " WHERE 1 = 1";
if (numSerieMaquina != null)
if (numSerieMaquina.indexOf('%') == -1)
strQuery += " AND num_serie_facturacao = " + numSerieMaquina;
else
strQuery += " AND num_serie_facturacao LIKE '" + numSerieMaquina + "'";
When I execute the JSP I see a page with the text FINALLY !!!
But an exception was thrown and I can't,
see
out.println("<P>" + "There was an error doing the query:");
out.println ("<PRE>" + sqlEx + "</PRE> \n <P>");
in the jsp page
application.log("Exception lan?ada", sqlEx);
don't know where to find the log file
throw new Exception(sqlEx.toString());
isn't caught by the error page error.jsp
What am I missing here ? a lot of stuff no doubt !
Can anyone give me suggestion(s) on how to detect an Exception ?
I would also apreciate a site with documentation regarding Exception processing inside JSP.
Many thanks,
MGoncalv

Hi there,
I'm building my first JSP application. I still don't
know what happens to an exception thrown inside a
scrptlet in a JSP page.I believe that any scriptlet exceptions get wrapped into a ServletException. At that time, if you have an errorPage defined for you JSP page, then it will go there. If you don't then the server will try to find the particular exception type in an <error-page> stanza in the web.xml. If it finds a mapping, it will go to that mapping, otherwise it will go to a default error page (container specific).
A quick glance at your design shows some big problems though that you may or may not hit (depending on how often you hit the page in your testing). The primary one is that in your PCliente class, you are opening up database connections/statements/results sets w/o closing them. You will run out of connections/cursors at some point b/c of this. You need to do your reads from the database and then close those resources (in a finally block to make sure they get closed). Read the data in a lightweight java object that the JSP can use to actually get the data.
Also, you only need to register the driver manager once. You can do this in static initialization block.

How to find exception occured while using LOGON function in oracle 10g

Hi,
I am using LOGON function to login with a different user name in oracle 10g forms.
LOGON ( User, Pass@tns, FALSE)
The third parameter is passed as 'FALSE' to avoid the login screen to be opened. If any of the other parameter ( User Name, Password, TNS) is passed wrong, connection is not established but no exception is occurred. The value for 'FORM_FAILURE' is set to 'TRUE'.
What i need is the ORA error for connection failure. The error message related to user name/password (ORA-01017) or connection identifier (ORA-12155).
How i can get this error code if connection is failed. Is there any other way to login in oracle forms other than 'LOGON'.

If you pass FALSE in login you can't catch anything. Want to catch the error ?
Then change
LOGON ( User, Pass@tns, FALSE)
to
LOGON ( User, Pass@tns, TRUE) Now Create On-Error trigger at form level
and try the following code
if error_code=01017 then
     message('invalid user name or password');
     message('invalid user name or password');
     raise form_trigger_failure;
elsif error_code=12154 or error_code=1215 then
     message('invalid connection string');
     message('invalid connection string');
     raise form_trigger_failure;
end if;Hopes this helps
