Not if you don't provide the code you are using so we can see what it is doing. Also post your 4 digit Oracle version, Java version, JDBC jar file name/version and the procedure signature that shows the language, parameters and types.
An ArrayList is a Java object so are you using a Java stored procedure?
Or are you using WebSphere? If WebSphere see this IBM link which appears to apply to the problem you are describing.

Class cast exception about oracle db

I want to store image file into BLOB of oracle datebase.
first, i insert a empty BLOB, like "insert into tableName (blobField, ...) values(empty_blob(), ...)"
then, i will retrieve this record to update the BLOB field, like "select blobField from tableName ..."
when i want to cast java.sql.ResultSet to oracle.jdbc.driver.OracleResultSet,
like "BLOB = ((OracleResultSet)rs).getBLOB(1);"
exception throwed:
java.lang.ClassCastException: weblogic.jdbc.rmi.SerialResultSet
the connection is get from connection pool of weblogic.
otherwise, if i register a new single connection, it can work correctly.
of course the same jdbc driver is used.
who can tell me, where raise the problem?
Thanks!

Don't cast to OracleResultSet but use the WebLogic API to set/get BLOBS:

Oracle Arrays and getVendorConnection API and Class Cast Exception

I 've gone through various threads relating to the topic of Oracle Arrays and the getVendorConnecton API call to avoid the class Cast Exception.. i ve used all these but am still facing the problem...
I would appreciate it if some one could resolve the following queries :
I am using Weblogic 8.1 SP5 with oracle 8i
1. I read that the need to use the getVendorConnection API to make pl/sql proc calls with oracle arrays from the WL Server wont be required to avoid classCastException...
I tried to use the connection from the WL connection pool ..but it didnot work....I used the getVendorConnection API ..which also doesnot seem to work..
I got the Heurisitc Hazard exception...I used the Oracle 9i driver ie ojdbc14.jar ...after this the exception is not coming but still the code doesnt seem to work...
the snippet of the code is pasted below :
~~~~~~~~~~~~~~~~~~~~~~~code is : ~~~~~~~~~~~~~~~~~~~
/*below :
logicalCon is the Connection from the WL connection pool
JDBCcon is the JDBC connection. */
<div> try </div>

I have observed that the control immediately comes to the finally block after the call to the createDescriptor line above with <u>^%^%^%</u> in the comment. If i use the JDBCCon in this line...it works perfectly fine.
Any pointers to where anything is getting wrong.
I have jst set the vendorCon to null in the end of the file and not closed it. Subsequently i have closed the logicalCon. This has been mentioned in some of the thread in this forum also.

Class Cast exception in ArrayDescriptor.createDescriptor(

I want to pass an array into a an Oracle procedure called using a callableSatement.
When I create the array descriptor i get an class cast exception. I believe this error occurs when the sun.jdbc.odbc.JdbcOdbcConnection
or the weblogic.jdbc.wrapper.PoolConnection_weblogic_jdbc_oci_Connection connection object is being cast to oracle.jdbc.driver.OracleConnection by createDescriptor method how can i overcome this run time error????

Class Cast exception when clicking Search Button in Query component

Hi
We have to implement the Query component in ADF programmatically.. We are using Toplink as the Model layer for ADF.
We followed the Web User Interface Guide for ADF development, Chapter 12 (Using Query Components) for the same.
We already have implemented the following classes:
1) QueryModel
2) QueryDescriptor
3) AttributeDescriptor
4) ConjuctionCriterion
5) AttributeCriterion etc.
We are able to see the Search panel in UI with selected fields in Basic as well as Advanced mode.
When we click on Search button, we are getting Class Cast exception.
The stacktrace of the exception is below:

I am working on a project that utilize Oracle Ultra Search that will crawl and tag documents in the database.
The initial code that uses pure JDBC was working fine, but when we switch to get database connection from dataSource, we are getting classCast exception inside Oracle's ultra search. The problems is that the class we get from dataSource.getConnection() returns
"weblogic.jdbc.wrapper.JTSConnection_oracle_jdbc_driver_T4CConnection". But Oracle UltraSearch is not expecting that.
Is there anyway to unwrap the connection that we get from dataSource ? I tried casting to OracleConnection,
assign the connection to "oracle.jdbc.driver.T4CConnection" without any success.
Any help would be appricated.
ThanksHi Gary. If the code you want to run is running inside WebLogic, such as in a JSP,
then look for our documentation on our JDBC extension 'getVendorConnection()". It
will get you a direct Oracle connection for their mis-declared UltraSearch
classes (they declare they take java.sql.Connection, but they really demand a
concrete thin driver connection. No other Oracle driver will be given a chance).

View Criteria in ADF Query Panel with Table-Class Cast Exception

Hi,
I am getting Class Cast Exception when using view criteria for ADF Query Panel with Table. The version I am using is 11g Release 1(11.1.1.2.0)
Here is what I did:
1. created a view criteria on a view object
2. all are optional
3. all are Strings
3. Dragged the view criteria as a query component (ADF Query panel with Query table) on to the design layout
and the error when I clicked the Search button is:

Hi Frank.
I'm using JDev 11.1.1.3.0 as you suggest the error is no longer present in the latest version.
I can pick my query from the "Saved Search" pick list on the QueryPanel list of queries just fine, and it sets up the filter properly, but when I press the "Search" button, I get the same reported error...

Class Cast Exception running Kodo JCA in Weblogic 8.1

Hi,
I have a stateless session EJB that accesses Kodo through the JCA adapter.
The database I'm connecting to is mysql.
The problem I'm having is that the persistence manager throws a class cast
exception when trying to commit the transaction. See below for the stack
trace. I suspect it has something to do with the mapping, but the error
doesn't give me enough information to tell.
Any idea where to start looking to solve this problem?

Can you use 3.1.5. Can you also be sure that you don't have multiple
versions of Kodo around, i.e. in the system classpath, JCA kodo.rar
directory, etc?

Thanks,

You should use prefer-application-packages when there is any conflict of classes specifically when the same class is being loaded by weblogic server.
When your using prefer-application-packages you should always set prefer-web-inf-classes to false.
This is documented please check following docs.
http://docs.oracle.com/cd/E24329_01/web.1211/e21049/weblogic_xml.htm#autoId24

Hai DigitalDreamer,
Thanks for giving your valuable time to my question.
I have tried the code you gave me.
The answer for :
out.println(objref.getClass().getName());
that i got is :
javax.naming.Reference
And the answer for :
out.println(objref.getClass().getInterfaces());
that i got is :
[Ljava.lang.Class;@213b6e
Could you please tell me how this can help.
Actually i am new to jsp.
Thanks in advance

'Class Cast Exception' while invoking a EJB from a Servlet

          Hi,
          I am working on J2EE applications.I am using Webgain studio and weblogic server.I
          got a problem while invoking EJB from the servlet.
          While calling an EJB from the servlet, it is giving that "Class Cast Exception".This
          is because, the remote home reference is not able to type casted to the"Home Interface"
          of the EJB, even if I type casted explicitly. It is creating the context and able
          to identify the EJB with the JNDI name.
          Could please help me in solving this problem.I am pasting the code here.
          Thanks in advance,
          Dharma
          public void doGet(HttpServletRequest req, HttpServletResponse resp)
               throws ServletException, IOException
                    resp.setContentType("text/html");
                    PrintWriter out = new PrintWriter(resp.getOutputStream());
          try
          Context context=getInitialContext();
          Object reference=context.lookup("ArlProjContractorAppletSession");
          ArlProjContractorAppletSessionHome home=(ArlProjContractorAppletSessionHome)PortableRemoteObject.narrow(reference,ArlProjContractorAppletSessionHome.class);
          //Exception is occuring in the above statement. It is unable
          //to cast to the home interface
                    ArlProjContractorAppletSession the_ejb=null;
          try
          the_ejb=home.create();
          System.out.println("the_ejb = " + the_ejb.toString());
          catch(Exception e)
          e.printStackTrace();
          catch(Exception e)
          e.printStackTrace();
                    // to do: code goes here.
                    out.println("<HTML>");
                    out.println("<HEAD><TITLE>Contractor TimeTracker</TITLE></HEAD>");
                    out.println("<BODY>");
                    // to do: your HTML goes here.
                    out.println("</BODY>");
                    out.println("</HTML>");
                    out.close();


          I came across this kind of problem once. My problem went away after I upgraded
          from 5.1 SP6 to 5.1 SP8.

Class Cast Exception in a custom adapter processing module

Hi,
I am trying to create a Custom adapter module in my file adapter as a Local enterprise Bean.
I have taken the "ConvertCRLFfromToLF" sample given by SAP as a reference, created an EJB module project, and deployed the enterprise archive to the J2EE engine.
However, i am getting a Class Cast Exception in the Adapter Engine for my communication channel.
Any help on this will much appreciated.
Thanks & Regards,
Renjith.

HI,
Managed to solve this..this was due to the additional jars which was included by the Developer Studio in the EAR file. We have to remoce the jars from the EAR, change the application.xml and sap_manifest.mf files to give reference to the jars already deployed in the J2EE engine.
Thanks & Regards,
Renjith

Class Cast Exception

Hi
I got class cast exception here
String value = String.valueOf
(((IPrivateMaterialApplicationView.IMaterial_InputElement)(wdContext.nodeMaterial_Input().nodeT_Matno_in().getElementAt(i))).getMatnr());
valueSet.put(value,value);
Thanks & Regards
Ravi Shankar B

Ravi,
the cause of this issue is that
wdContext.nodeMaterial_Input().nodeT_Matno_in().getElementAt(i)
does not return an instance of type
IPrivateMaterialApplicationView.IMaterial_InputElement
Check what type is returned by this method (in NWDS place your cursor over the method and the return type is displayed) and cast to that type.
Regards
Sebastian

Class cast exception using Finder method

Hello. I'm new to J2EE. I have set up one entity bean but am having trouble
with my current one.
Basically, I have two finder methods:
public ShareHistory findByPrimaryKey(Integer historyId)
        throws FinderException, RemoteException;
    public Collection findByShare(String shareId)
         throws FinderException, RemoteException; findByPrimaryKey works fine, but findByShare causes a class cast exception in java.lang.String.
The stack trace in the server logs shows that it is my ejbActivate method in my entity bean causing the problem:
public void ejbActivate() {
      //String numberString = (String) context.getPrimaryKey();
      //historyId = new Integer(numberString);
    historyId = (Integer) context.getPrimaryKey();
    }The stack trace from my client shows that the class cast exception occurs
in the client at the System.out.println("shareid" + ": " + sh.getShareId());
line:
Collection c = sharesHistoryHome.findByShare("DCAN");
                 Iterator i = c.iterator();
                      while (i.hasNext()) {
                     ShareHistory sh = (ShareHistory) i.next();
                System.out.println("shareid" + ": " + sh.getShareId());
                System.out.println("value" + ": " + sh.getValue());
                 System.out.println("time" + ": " + sh.getTime());
                 System.out.println("date" + ": " + sh.getDate());
                 }//whileAs you can see I tried casting to a string in ejbactivate, but that simply causes an Integer class cast exception during findByprimaryKey instead. How do I allow both Integer and String objects to be used?
Also I am a bit confused as to why the String passed to findByShare(String) is being used in context.getPrimaryKey() in the first place (if that is actually what's happening).

Oops my FindByShare method was returning a collection of shareId's (strings) instead of a collection of Integer primary keys, which would explain the class cast exception.

(Class cast Exception)Problem while loading data fro database in java class

Dear all,
Please help me...to solve this
I have a database having two columns of String and Date Types.
In my java code i was trying to load the data to a UI.
I am successfull in loading the String type value.
But while loading date field value,is showing Class cast Exception.
What i am doing is Getting the values from database to a String[] array.
So my question is how to
get the Date field as date field itself,Then convert it to a String..Then put it in to String[] array...
Any body please help...If any one want more clarification in question i will give......

Hi,
I am using GWT to display my data in a Grid.
So it will accept a Single two dimensional String array....Here i have one as String and other as Date.
So i was trying to get each row in a sindle dimensional array array[] then store it in a list.
Iteration goes up to 10 rows.After i am setting it in to a list
ie list.add(array);
Now while returning this list i am doing this
"return (String[][])list.toArray(new String[0][]);"
When i tried to get the date element to String array it is showing class cast exception. When i tried with toString() method it is showing the same problem.
