Retrieving a LOB object in OAS

I've got a Servlet that is used to retrieve a
binary file from the database il blob format.
The code works great using JDeveloper's web server but it crashes in OAS with "Internal error" as the only explanation.
This is the code, the last line is the one that causes the problem.
Statement stmt = conn.createStatement ();
ResultSet rset= stmt.executeQuery("select * from scott.scraplob");
if(rset.next()) {
BLOB blobPDF= ((OracleResultSet)rset).getBLOB(2); // this causes an internal error
null

<c:forEach var="columnName" items="${requestScope.searchResults}">

Oracle 8i array DML operations with LOB objects

Hi all,
I have a question about Oracle 8i array DML operations with LOB objects, both CLOB and BLOB. With the following statement in mind:
INSERT INTO TABLEX (COL1, COL2) VALUES (:1, :2)
where COL1 is a NUMBER and COL2 is a BLOB, I want to use OCIs array DML functionality to insert multiple records with a single statement execution. I have allocated an array of LOB locators, initialized them with OCIDescriptorAlloc(), and bound them to COL2 where mode is set to OCI_DATA_AT_EXEC and dty (IN) is set to SQLT_BLOB. It is after this where I am getting confused.
To send the LOB data, I have tried using the user-defined callback method, registering the callback function via OCIBindDynamic(). I initialize icbfps arguments as I would if I were dealing with RAW/LONG RAW data. When execution passes from the callback function, I encounter a memory exception within an Oracle dll. Where dvoid **indpp equals 0 and the object is of type RAW/LONG RAW, the function works fine. Is this not a valid methodology for CLOB/BLOB objects?
Next, I tried performing piecewise INSERTs using OCIStmtGetPieceInfo() and OCIStmtSetPieceInfo(). When using this method, I use OCILobWrite() along with a user-defined callback designed for LOBs to send LOB data to the database. Here everything works fine until I exit the user-defined LOB write callback function where an OCI_INVALID_HANDLE error is encountered. I understand that both OCILobWrite() and OCIStmtExecute() return OCI_NEED_DATA. And it does seem to me that the two statements work separately rather than in conjunction with each other. So I rather doubt this is the proper methodology.
As you can see, the correct method has evaded me. I have looked through the OCI LOB samples, but have not found any code that helps answer my question. Oracles OCI documentation has not been of much help either. So if anyone could offer some insight I would greatly appreciate it.

Before 9i, you will have to first insert empty locators using EMPTY_CLOB() inlined in the SQL and using RETURNING clause to return the locator. Then use OCILobWrite to write to the locators in a streamed fashion.
From 9i, you can actually bind a long buffer to each lob position without first inserting an empty locator, retrieving it and then writing to it.

Retrieving a ref object from complex object table

Hai All,
I have problem retrieving a ref object. The scenario is as follows:
create type typ1 as object (c1 number, c2 varchar2(25));
create type typ2 as object (c1 number, c2 ref typ1);
create table tab1 of typ2;
I generate the java classes using the jpub. When I retrieve the values from the table using the java class, it gives me the null pointer exception.
typ1Ref r1 = typ2.getC2 ();
typ1 t1 = r1.getValue ();
System.out.println ("value: " + t1.getC1 ());
Above is the code after I have fetched the values in the result set.
Could anyone help me upon this.
Thanks in advance,
Anand

Sounds like your C2 REF TYP1 attribute may be null. Unfortunately you neglected to say where in your code the NullPointerException occurs.

How to retrieve the java object in a proxy service in osb -- Plz help

Hi all,
I have a singleton java class which runs whenever the weblogic server gets started and store the output in its object. I need to access this java object from a proxy service in osb.
We tried using java call out and retrieved that object but we couldn't know how to parse that object into XML.
We are not sure of using the java call out in osb to solve this purpose because whenever we use a java callout, that particular java code will run which is not the case of singleton class.
So kindly help us how to retrieve the java object which holds the output without running the java code every time because its already run and holding the output in its object.
Regards
Prabhu

here the doc http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1106656
but I guess you are already at the stage of getting a POJO in a first Java Callout and passing the POJO to a second Java Callout, which should then return it to OSB as a XMLObject.
My recommendation is to write a Java function which returns a XMLObject and uses a XMLCursor to populate it with the values of the POJO.
An XMLObject returned to the OSB is automatically transformed in a "XML" variable (which in reality is represented as a XMLObject in the Pipeline context)
Here some code sample:

Retrieving a UDT object from a Java Stored Procedure

I am really having trouble returning a UDT object (AttributeUDT) from a Java stored procedure. I am using Oracle 8.1.6 and JDeveloper 3.2.2. I have successfully used JPublisher to create the Java source code files for my UDT, now I would like to use that in coordination with my Java stored procedure. I've loaded the Java stored procedure into the database using the Deployment option in JDeveloper. However, when it loads the procedure, it translates the 3rd parameter to an OBJECT type, thus making the stored procedure invalid. I can use SQL Navigator to correct the package by changing the OBJECT reference to AttributeUDT (my UDT data type). Unfortunately, my Java stored procedure still does not work. Any help would be greatly appreciated! Thanks in advance for your time!
In the example below, could anyone please tell me:
1. How do I register the OUT variable for the UDT?
2. Is it correct to use the casted call to getObject to retrieve my UDT object?
3. Is it valid to use the UDT data type in the java stored procedure method signature?
The call to the Java stored procedure:
OracleCallableStatement cs3 = (OracleCallableStatement)conn.prepareCall( "{ call sandbox.getQualifiersV3( ?, ?, ?) }");
cs3.registerOutParameter( 1, Types.VARCHAR);
cs3.registerOutParameter( 2, Types.VARCHAR);
cs3.registerOutParameter( 3, ???????);
cs3.execute();
System.out.println( "ID: " + cs3.getString( 1));
System.out.println( "Prompt: " + cs3.getString( 2));
AttributeUDT attributes = (AttributeUDT)cs3.getObject( 3);
System.out.println( "Table id: " + attributes.getLogicalTableId());
System.out.println( "Element id: " + attributes.getElementId());
cs3.close();
===========================================
The Java stored procedure:
public static void getQualifiersV3( String ids[], String prompts[],
AttributeUDT attributes[]) throws SQLException {
OracleConnection conn = (OracleConnection)new OracleDriver().defaultConnection();
Statement stmt = conn.createStatement();
OracleResultSet rs = (OracleResultSet)stmt.executeQuery(
"SELECT * "
+ "FROM VPS_ABOK_QUALIFIERS "
+ "WHERE qualifier_id = 2001");
rs.next();
ids[0] = rs.getString( 1);
prompts[0] = rs.getString( 2);
attributes[0] = (AttributeUDT)rs.getCustomDatum( 3, AttributeUDT.getFactory());
rs.close();
stmt.close();

Retrieving Session bean object in a Servlet from FacesContext Object

Hi,
I added code in a servlet to retrieve Session bean object from the Faces Context object. I don't know what the problem was, but when I am accessing the application from two different machines and I am trying to retrieve the value from the session object in the servelet it is giving the value what I set into the session bean on one machine browser into another machine browser. Just I want to know the code which I had included in the servlet is correct or not.
This is the code I am using in my servelt:
1) To get the Faces context object
protected FacesContext getFacesContext(HttpServletRequest request, HttpServletResponse response) {
     FacesContext facesContext = FacesContext.getCurrentInstance();
     if (facesContext == null) {
          //System.out.println("Current context was null...creating one now");
          FacesContextFactory contextFactory =
               (FacesContextFactory)FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
          LifecycleFactory lifecycleFactory =
               (LifecycleFactory)FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
          Lifecycle lifecycle = lifecycleFactory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
          facesContext =
               contextFactory.getFacesContext(request.getSession().getServletContext(), request, response, lifecycle);
          //Set using our inner class
          InnerFacesContext.setFacesContextAsCurrentInstance(facesContext);
          //set a new viewRoot, otherwise context.getViewRoot returns null
          UIViewRoot view = facesContext.getApplication().getViewHandler().createView(facesContext, "ContextName");
          facesContext.setViewRoot(view);
     return facesContext;
2) Code to get the session bean:
Utils utilsBean = (Utils) getFacesContext(request, response).getApplication().getVariableResolver().resolveVariable (getFacesContext(request, response), "utils");

Hi Raymond,
Thank you for the reply and can you please send the code No, I cannot do that.

How to shrink LOB objects storage

Hello,
I am wondering if some one can answer my question about: In Oracle 9i after deleting LOB objects still the size of file remains same and it does not shrink/delete when those LOB objects are deleted.
Is there any command which can delete or shrink the size of the storage which was used my deleted LOB object?
Thanks

Check this link..

>
once an extent is allocated to a table -- it will belong to that table until you drop
the table, truncate the table, or explicitly deallocate the extent (which only works if
the extent NEVER contained any data whatsoever)
This is totally expected. the space is there, the space is available, the space is free
for use but ONLY by this segment. The tablespace will not change in regards to free/used
space -- the extent belongs to that table and will stay with that table. It is however
FREE SPACE in the table.
>
From Oracle 10g and above, you can use the "Alter table Shrink" command to manually shrink the object.
