Thanks for the help in advance..

It seems you have used a taskflow on a page and one of the binding.
It will be easy to point out if you paste the code of region tag *<af:region.......*.

Hi timo,
Thanks for ur reply...
we are using unbounded taskflow.
In Controller class(page def file), we refered the class that implements PagePhaseListener
The following override methods has created
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
//In this area we used to read the session object file which is written and sent by another application(application to application navigate).
If session object file exists,will allow the user to navigate into the requested page else will navigate in to login(security aspect).
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
Is we used Controller class wrongly ???
Is there any relationship with region controller???

Oracle.jbo.uicli.binding.JUIteratorBinding cannot be cast to oracle.adf.

HI ,
I'm using ADF 11g,
I'm working on individual work space. i have used oracle.adf.model.binding.DCControlBinding in my bean class and working fine .Now one day before i have taken svn version repository project and started working .I made simple jspx with adf table and tool bar button such as Add. When i fire add button i'm calling a method in bean class.
public String createRecord() {
// Add event code here... bank_add
System.out.println("-- create record --");
BindingContainer bindings2 = ADFUtils.getBindingContainer();
DCControlBinding dcc = (DCControlBinding)bindings2.get("XbtBankSettlementVOIterator");
return "banksettlement_add";
surprisingly i got this error.when my fellow colleague is using same svn repository project and using oracle.adf.model.binding.DCControlBinding it is working fine.
but why i'm getting this error below.i have followed the same steps to create View Object and Entity Object as previous .

Java.lang.ClassCastException: java.lang.Short

It(He,She) gives me the exception java.lang. ClassCastException: java.lang. Short, the complete code is:

In the line 36 what I have is:

Which can be the problem? Something on having done the casting?

It(He,She) it

Hi Dr,
I followed your suggestion, but there was no casting to double in the JSP code, so I looked at the database and found 3 columns inadvertently created as "double default null" when the MSAccess mdb was exported to MySQL.
I modified the database to make those columns text, and now the compiler does not throw the error.
I'm still unclear why the error was thrown.

Oracle.sql.STRUCT cannot be cast to oracle.sql.STRUCT

I met a problem,I use oracle spatial to store geometry,then get it like this:

Hi, this is a known problem for most Spatial 10g Java APIs with WLS.
WLS is only certified with 11g DB.
Instead of using Weblogic JNDI Lookup for Datasource, try the following snippet to create your connection/datasource (with Oracle JDBC thin driver):
String databaseUrl = jdbc:oracle:thin:@1.2.3.4:1521:yourdbname
String databaseUser = dbusername
String databasePassword = dbpassword
DriverManager.registerDriver(new OracleDriver());
Connection aConnection = DriverManager.getConnection(databaseUrl, databaseUser, databasePassword);
For more information, see the following:

Javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOB

Hi there,
I'm facing this exception.
My code:
final ReportTemplateAttachment rta = new ReportTemplateAttachment();
FileBlob fb = new FileBlob();
fb.setContentType(attachmentDto.getContentType().getValue());
fb.setCreationDate(sysDate);
fb.setCreationUser(userId);
final SerialBlob blob = new SerialBlob(attachmentDto.getFileVal());//it's a byte[]
//SerialBlob is of type javax.sql.rowset.serial.SerialBlob
fb.setFileData(blob);
fb.setName(attachmentDto.getFileName());
fb.setLastUpdateDate(sysDate);
fb.setLastUpdateUser(userId);
fb.setLength(blob.length());
rta.setFileBlob(fb);and the object rta will be inserted into another object.
The variable of interest in FileBlob hbm is defined as follows:
<property name="fileData" type="blob">
<column name="FILE_DATA" />
</property>where the type blob is oracle.sql.BLOB
If I change the oracle.sql.BLOB to javax.sql.rowset.serial.SerialBlob in the hbm, I can insert but when I try to get the blob back I get a deserialize exception so this change is not an option.
but when I save the main Object (a cascade operation) I get the following exception:
org.springframework.jdbc.UncategorizedSQLException:
Hibernate flushing: could not insert: [pt.sc.data.entities.FileBlob];
uncategorized SQLException for SQL
[insert into WP_ADMIN.file_blob (name, content_type, length, file_data, status, creation_user, creation_date, last_update_user, last_update_date, id)
values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)];
SQL state [null];
error code [0];
An SQLException was provoked by the following failure: java.lang.ClassCastException:
javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOB;
nested exception is java.sql.SQLException: An SQLException was provoked by the following failure:
java.lang.ClassCastException: javax.sql.rowset.serial.SerialBlob cannot be cast to oracle.sql.BLOBAny light on the subject?
Thanks in advance,

You don't seem to understand the difference between an object model and a database. Hibernate, being an ORM package, works on the object model and will, based on what you request it to do, generate proper SQL statements to get the database part going. But you shouldn't be thinking about databases when using Hibernate; your main focus is the object model. There is no blob, only binary data. Binary data in Java is generally handled through a byte array.
If you want to think in databases where blobs do exist, you should be using JDBC directly, not Hibernate.
(I'm far from being an expert in Hibernate)I would really suggest taking a few hours and reading through the manual. You don't need to be an expert but you should at least know what kind of tool you're working with.

Caused by: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlHierNodeBinding cannot be cast to oracle.jbo.uicli.binding.JUCtrlValueBindingRef
The line of code in the backing bean caused the error:
oracle.jbo.uicli.binding.JUCtrlValueBindingRef tableRowRef = (oracle.jbo.uicli.binding.JUCtrlValueBindingRef) this.getTable1().getRowData();
What bugs me is that the same code works fine in another page's backing bean (see *1) and I can't find out the difference.
My environment:
I am using JDeveloper 11. The application I am working on was migrated from a JDeveloper 10g app, so the components are mostly Trinidad. We had to do a lot adjustment to get that app to work in 11g. The working page I mentioned above was done in 10g app (*1).
I am now adding more things into this app. The app's setup is EJB session beans and Trinidad components now.
In the jspx page, I have a table which was made up with a view from the database (NOT VO). I have a command link in a column in that table, and would like to get a Id from the row in the table. The line of code causes error above is in the command link's action method.
Please help if you have any clue.
Thanks a lot!
Sophia

Thank you so much Frank! It's just that simple. This is my first post question, although I had always looked up the forum for answers before. I am a big fan of yours. This is such a great experience on my first post. I am having a much better day than yesterday. :-) Thanks again!

Exception:org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

Hi All,
i am using jdev version 11.1.1.5.0
and deployed my Adf application on Apache Tomcat 6.0.
in my use case i have created simple adf application using adf business component. create a vo based on eo and drag-drop on jspx page.
i have created JNDI data source in Apache server using edit context.xml file and add following line-
<Resource name="jdbc/TestDB" auth="Container"
              type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@localhost:1521:dst"
              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1" accessToUnderlyingConnectionAllowed="true" />
3.using same data source in my adf applicatioin as -
right click on AM --> Configuration-->edit-->select connection type jdbc datasource -->java:/comp/env/jdbc/TestDB
4. after that i have deployed my application on apace server but when i have running application i have got following error-
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection
i have goggling and find following solution-
oracle.jdbc.driver.OracleConnection delConn = (oracle.jdbc.driver.OracleConnection) ((org.apache.tomcat.dbcp.dbcp.DelegatingConnection)c_stmt.getConnection()).getDelegate();
but my problem is that i'm using Adf Business Component so where i set following type casting.
Is there any method on ADF BC which handle JNDI Data source setting or any other way to do this.
thanks in Advance
Manish

Hi dvohra21,

i have already set this property on context.xml file
<Resource name="jdbc/TestDB" auth="Container"

              url="jdbc:oracle:thin:@localhost:1521:dst"
              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1" accessToUnderlyingConnectionAllowed="true" />

Why are you doing this cast anyway? I think you need to show a small bit of compilable code (or almost compilable except perhaps for this error) and some more explanation.

Java.lang.ClassCastException: java.lang.OutOfMemoryError

Hi everyone,
I am having this exception when I want to run my application (not always so). I have to restart the server and il works again fine.
But I don't see the relation between a ClassCastException and the OutOfMemoryError.
Can anyone tell me ?
Thanks

you're right.
I have a cast with Exception. I have not understood the OutOfMemoryError was not an exception.
So I have 2 errors : the first one is the OutOfmemory and the second one is the cast.
Do you agree ?
