Oracle.sql.STRUCT

Hi,
when I use functions that returns a geometry (for example SDO_GOEM.SDO_BUFFER, SDO_GEOM.SDO_DIFFERENCE) I have in return oracle.sql.STRUCT@6c08b2..
What can I do!?
thanks

as far as I know, the STRUCT is the returned geometry. so you can declare a SDO_GEOMETRY variable and assing the STRUCT directly to this variable.
For example you have a variable 'geo_variable' and assign it the result of a function like this:
geo_variable := SDO_GEOM.SDO_DIFFERENCE(geom1, geom2, tol );
what you see written like this "oracle.sql.STRUCT@6c08b2.." I believe is the stuct @ the memory address 6c08b2..

Oracle sql STRUCT query

Hi all. I have a simple program running in JDeveloper using JDBC for retrieving SDO_Geometry values from various spatial tables. The program works fine but when I run the following SQL statement to retrieve the geometry column from a table states it is returning the sdo_geometry values in the following format:
spatialQuery = "select a.geom from states a";oracle.sql.STRUCT@e2dae9,
oracle.sql.STRUCT@19209ea,
oracle.sql.STRUCT@c8f6f8,
oracle.sql.STRUCT@1ce2dd4,
oracle.sql.STRUCT@122cdb6,
I know the program works but can anyone tell me how to interpret these results or even how to translate them into a more useful format. Cheers Joe

I assume you are getting back a List (Vector) with the Struct inside it. Try ((List)query.getSingleResult()).get(0).
In JPA you should get the Struct back directly if the result size was 1, otherwise an Object[], this was a bug in EclipseLink 1.0 that was fixed in EclipseLink 1.1.
You should probably upgrade to EclipseLink 1.1.

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:
STRUCT dbObject = (oracle.sql.STRUCT)rs.getObject("shape");
JGeometry geom = JGeometry.load(dbObject);
tomcat 6 told me java.lang.ClassCastException: oracle.sql.STRUCT cannot be cast to oracle.sql.STRUCT
does everyone knows this problem?thanks

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);

Oracle.sql.STRUCT and returns from procedures

I need to know how to retrieve information out of a stored procedure. I have a stored procedure that has a IN/OUT parameter that is used to return an array of an oracle TYPE that is set up in the database (it consists of two numbers and a varchar2. So I am returning an array of these types). I need to call this stored procedure from JDBC and retrieve the data out of it. I can setup the outParameter of the statement and also get the Object out of the statement once the procedure is called. But what is returned to me? An array of oracle.sql.STRUCT objects? A single oracle.sql.STRUCT object? A multi-dimensional array of java objects? Or something else?
Thanks

Java.lang.NoClassDefFoundError: oracle/sql/STRUCT after 11g/GF3.1.2 upgrade

We have recently upgraded all of our servers from:
Java 1.6.31 to 1.6.32
and
Glassfish 3.1.1 to 3.1.2
We upgraded our development server from Oracle 10g to 11g.
Our live servers are working fine. Our development server now is spewing out a java.lang.NoClassDefFoundError: oracle/sql/STRUCT error whenever it encounters a servlet or page which uses this class.
ojdbc14.jar and sdopai.jar were included within the WAR file, and I have tried with them excluded from the WAR file to no avail. We have tried reverting the version of ojdbc.jar on the server to the earlier version, this has made no different.
Any ideas? The full stack trace is below:

If your code can't find the class then you have the classic NoClassDefFoundError problem you get when any other referenced class can't be located.
The oracle/sql/STRUCT class is in the ojdbc14.jar, ojdbc5.jar and ojdbc6.jar so if it can't be found then that class is missing from the jar you are using (which you can tell by examining the jar contents) or the jar is missing from the classpath being used.
As already mentioned you need the Oracle 11 JDBC files to support Java 1.6
Here is the official Oracle JDBC page that shows the Oracle DB versions supported for each of the JDBC drivers available and also describes the JDBC jars and what JDK versions they support.

Obtaining an oracle.sql.STRUCT through a pooled JDBC connection

Hello,
I am using WebLogic Server 10 and and Oracle 10 and I am trying to obtain a vendor-specific oracle.sql.STRUCT from a ResultSet using a pooled connection defined in Weblogic. I need the vendor-specific object, rather than simply the java.sql.Struct implementation, because a third party library requires it.
What gets returned in the ResultSet is a non-exposed WebLogic wrapper object which implements java.sql.Struct, but which cannot be cast to an oracle.sql.STRUCT. I can use reflection on this object to find and call the getVendorObj() method to obtain the oracle.sql.STRUCT, but this solution is not acceptable because this is not a published API and is not guaranteed not to change in future versions.
How can I reliably obtain a vendor-specific implementation of java.sql.Struct through a WebLogic connection pool in WebLogic Server 10?
Thanks for any advice,
-Dan Schwemlein

Joe,
Thanks again. With your guidance, I have arrived at the following approach, which I'll post for the benefit of others, and which I'd be thankful if you would validate:
1) Import the jar com.bea.core.datasource-1.0.0.0.jar from %BEA_HOME%\modules, which is the only location of the class WLConnection, which is the only class with the getVendorConnection() method you refer to.
2) Get the logical connection from the pooled data source, cast it to a WLConnection, call getVendorConnection() to obtain an OracleConnection (from the ojdbc jar), and use this connection to obtain the required oracle.sql.STRUCT from an OracleResultSet.
3) Be aware of the limitations and follow the guidelines in the document http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html#1043646 regarding security, error handling, releasing resources (close only the logical connection), etc.
Does this sound like the approach you had in mind?
Thanks again,

Thank you for the information about the connection being closed.
I will look into using this configuration setting.
You say that you can describe a way to get a handle on an unwrapped
pool object using some documented WLS-specific code. Are you referring
here to the getVendorConnection() method?yes.
This method does not help me
get the oracle.sql.STRUCT object, because even the connection returned
by getVendorConnection() returns a wrapped WL java.sql.Struct object
from a call to getObject().I don't believe it. If you are running in WLS, with a local pool,
the getVendorConnection() will give you the Oracle connection,
which will give you an Oracle statement, etc, down to an oracle
STRUCT object. Once you have a direct reference to the oracle connection,
we're not in the picture when it returns something to you.
It would be great if getVendorObj() were
documented and could be counted on in future versions. To use this
method, one would still have to access it via Java reflection, because
the wrapper class and its getVendorObj() method would be exposed in an
API, correct? Could this method be exposed in the API, so that reflection
doesn't need to be used, or it is exposed somewhere that isn't documented?getVendorObj() is not yet exposed or therefore supported for the general
wrapped object, so you would have to start from the connection and
derive all subobjects from it.

but we could also wish Oracle had done so with it's driver objects.
I will assume your code is running in the WebLogic server, because
an external JVM can never access the real driver object, which will
always really be in the WLS JVM. No active JDBC object is serializable.
How can I reliably obtain a vendor-specific implementation of java.sql.Struct
through a WebLogic connection pool in WebLogic Server 10?There is no way to get a handle on an unwrapped pool object without using some
WLS-specific code, though I can describe a way with documented methods,
and/or I can get our documentation altered to say we'll support the
getVendorObj() method. We introspect every vendor object, and for those
implementations that have done the wise thing, projecting any non-standard
methods as an Interface, we are able to also project that Interface so
the vndor example code should work. However, in some poorly-done
cases, such as for some Oracle stuff, there is either no Interface,
or the Oracle code has extensions that take java.sql objects as input,
(at least that's the signature of the method) but two lines into the
method, the Oracle code assumes and casts the java.sql object to a concrete
Oracle object. In these use cases you need the direct unwrapped object.
We provide and document Connection.getVendorConnection(), and intend
getVendorObj() to serve the same for subobjects, but note the dangers
and responsibilities: We rely on our wrappers to implement the security
and thread-safety of our pooling system. Because user code can get
unrestricted access to the actual connection from most JDBC objects,
we can never trust that we have complete control once a vendor object
is exposed. Therefore, by default we will close and replace every JDBC
connection so exposed, as soon as the current thread is finished with
the pool connection. This hurts performance. We also document a pool
config setting that will tell us that you take responsibility for any such
problems, and not to close connections just because they've been exposed.
HTH,

Using oracle.sql.STRUCT to pass in a COMPLEX OBJECT

I need to pass in a complex object (object with nested array of objects) into a oracle stored procedure.
We are using JDBC 9.2.0.1 drivers...
Note i am able to retrieve a complex object successfully using an oracle struct however i am not able to pass in the struct.
I do not want to use JPublisher as we are not using SQLJ.
I have looked through the documentation on using default structs and am getting an error when i try and create the struct...
I have created an array of objects with a sub array
and i create a struct descriptor however when i create the actual oracle struct
like
oracle.sql.Struct = new oracle.sql.Struct( structDesc,conn,complexobject)
I get a "java.sql.SQLException: Internal Error: Unable to resolve name"
Do i have to create STRUCTS for the nested object first ?
And then nest that STRUCT within the PARENT STRUCT to pass in complex objects ???
Any help would be much appreciated...

Problems retreiving varchar attributs from oracle.sql.STRUCT

Hi,
I have downloaded the Java + Oracle Object Types examples from the oracle homepage, but instead of the varchar values from a STRUCT the Java-application just displays "???". Numbers and dates are displayed correct.
Im running JDK1.4 on Windows and Oracle 9.2.0.8 on Unix with corresponding JDBC driver
Any idea?
Thanx in advance,
Jo

Jo,
I'm guessing it has something to do with your NLS / I18N settings.
Do you know what they are?
Usually, both JDK and Oracle assume an American environment.
In other words, American English, etc.
Is your environment different to this?
Good Luck,
Avi.

Oracle.sql.* with JDBC drivers 8.0.5

the oracle.sql package is not included in my JDBC driver file classes111.zip given for oracle data server version 8.0.5.
I would like to use the oracle STRUCT and ARRAY type for calling PL/SQL stored procedures taking STRUCT objects in arguments.
Are the JDBC drivers 8.1.* compatible with the oracle data server 8.0.5 (if I only use the STRUCT or ARRAY types)? Is it a way for passing ARRAY of VARCHAR2 values to PL/SQL stored procedure with the oracle 8.0.5 JDBC driver?
thanks

Unfortunately, these classes (oracle.sql.STRUCT and oracle.sql.ARRAY) are not compatible to 8.0 database. There is server format changes between 8.1 and 8.0, and JDBC driver only supports the 8.1 format.
Please upgrade your database to 8i.

Fail to convert to internal representation: oracle.sql.DATE

I'm using the oracle 8.1.7 jdbc driver against oracle 8.1.7 running on NT, and I get the exception message below when I attempt to insert an jpub object structure into a prepared statement.
All date objects have been constructed from a timestamp object, using the oracle.sql.DATE Timestamp constructor. So I'm surprised to get this error given the timestamp object was successfully constructed.
I've tried session date formats of 'yyyy-mm-dd hh24:mi:ss' and 'mm/dd/yyyy hh24:mi:ss', with no success.
I can call stringValue on oracle.sql.DATE and it returns a valid date.
Can someone confirm that they have been able to use the oracle.sql.DATE class to insert a date correctly into the database? Its seems a silly question to ask but you have to start somewhere!

The JPub/JDBC runtime is converting your Java object into Oracle-specific representation (all data is put in oracle.sql.XXXX format). The top level object is an oracle.sql.STRUCT, the attributes of which are represented as an array of oracle.sql.Datum objects - in your case an oracle.sql.NUMBER and an oracle.sql.DATE. However, the error does occur in the StructDescriptor which describes the SQL type and the shape of the object. Is the error dependent on the data values? Might null values not be dealt with, correctly?
One thing to try to do is create such an oracle.sql.STRUCT object from scratch with the same attribute values and insert/manipulate that using SQL.
I have not dealt with TAR's. If you send me a self-contained test case, I'll check it against the current development version of JDBC. (At least you'll know if the next JDBC release fixes this issue :-) I might also file a bug.

Getting oracle.sql.CHAR - II (I hope)

Hi all!!
Think I describe my problem badly - nobody answer to me...
There is a part of code:
OracleResultSet rs = db.getStoredItemList();
while (rs.next()) {
oracle.sql.STRUCT s = (oracle.sql.STRUCT)rs.getObject(1);
Datum[] attr = s.getOracleAttributes();
// cs = ((oracle.sql.CHAR)attr[1]).getCharacterSet();
System.out.println(attr[1].toString());
{Note: attr[1] - this is CHAR, in base - varchar2}
When I do rem line
cs = ((oracle.sql.CHAR)attr[1]).getCharacterSet();
in this case I can see in the consol window lines like
this - 0x4D6F6E69746F72, 0x555053 .... Another words -
hexadecimal representation, but not "Jhon Lennon" /for
example/. And when I open line cs = ....
then I get exception. Exception:
java.sql.SQLException: Non supported character set: oracle-character-set-171
 at oracle.gss.util.NLSError.throwSQLException(NLSError.java)
 at oracle.sql.CharacterSetUnknown.convert(CharacterSetFactoryThin.java)

 at oracle.sql.CHAR.<init>(CHAR.java)
 at test_clob.TheMain.<init>(TheMain.java:34)
 at test_clob.TheMain.main(TheMain.java:52)
WHY ??? In the database store ONLY strings /varchar2/ of
english words, not other languages.
Thanx.
Konstantin.

Hi Konstantin,
I guess, you should also add nls_charset12.jar/zip in your classpath environment variable.
This jar file can be found in the folder where you have classes12.jar/ojdbc14.jar [ ORACLE_HOME/jdbc/lib ]

Oracle.sql.ARRAY incompatible with weblogic.jdbc.vendor.oracle.OracleArray

Hi,
I am facing following issue in my one environment. but in other environment same class path is working fine. I have compared all jar and classpath for both weblogic server.
I am using weblogic 11g.

Creating my Oracle connection works fine ... code as follows:
Context ctxt = getInitialContext();
DataSource dataSource = (DataSource) ctxt.lookup(poolName);
Connection conn = dataSource.getConnection();
OracleConnection oracleConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
I also have reviewed documentation:
http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html. In section 'Using OracleStruct Extension Methods' it highlights that
java.sql.Struct struct =(weblogic.jdbc.vendor.oracle.OracleStruct)(rs.getObject(2));
None of the documentation actually mentions oracle.sql.STRUCT. For Weblogic to truely provide support for Oracle it needs an easy way of converting to this data type. At present I cannot interact with Oracle APIs until I can create an oracle.sql.STRUCT.

Issue with java.lang.ClassCastException: oracle.sql.StructDescriptor

Hi ,
I'm creating a dbadapter for a custom API written in APPS schema -
TYPE MISIPM_LOB IS RECORD (
FILE_ID IPM_LOBS.FILE_ID%TYPE,
FILE_NAME IPM_LOBS.LOB_NAME%TYPE );
TYPE MISIPM_LOB_LIST IS TABLE OF MISIPM_LOB;
PROCEDURE GET_FILE_ID_DETAILS(
P_SOURCE_SYSTEM IN VARCHAR2,
p_entity_value IN VARCHAR2,
p_entity_code IN VARCHAR2,
P_ORG_ID IN NUMBER,
P_MISIPM_FILES_LIST OUT MISIPM_LOB_LIST,
P_ERRCODE OUT VARCHAR2,
P_ERRMESSAGE OUT VARCHAR2);
From JDeveloper, there is a wrapper package is getting created and the compilation/deployment of this composite is also without any error.
But when I run the composite, I'm surprisingly getting the below error -
Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'GetAttachmentMetaData' failed due to: Interaction processing error. Error while processing the execution of the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API interaction. An error occurred while processing the interaction for invoking the APPS.BPEL_GETATTACHMENTMETADATA1.XX_DELIVER_BLOB$GET_FILE_ API. Cause: java.lang.ClassCastException: oracle.sql.StructDescriptor Check to ensure that the XML containing parameter data matches the parameter definitions in the XSD. This exception is considered not retriable, likely due to a modelling mistake. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution.
I recreated the adapter multiple times within the composite and also tried to create a separate composite and all the cases the error message received was same. There two more similar procedure call's in the composite and all rest of them are working fine.
I can call the wrapper from sql script separately.
Verified that the XSD generated and the wrapper package parameters are matching as well.
Did anyone face the same issue or any explanation/help is much appreciated.

Debanjan

How to use oracle.sql.* package?(in nls_charset12.zip)

is there anyone could tell me how to use the method in this package? for i want to convert a character set from the database (solaris)default character set to the client(win2000) while storing data into ResultSet.
or anyway that could chnage it would be appricate.
thanks in advice,

Hello Gaurav,
First off, not sure why you are calling
call.addNamedArgument("JOB_ID", "JOB_ID_I");
call.addNamedArgumentValue("JOB_ID", jobId);
You should call the first statement to indicate you will be adding in a "JOB_ID_I" argument to the query, or the second statement to add the value directly to the call, but not both. Calling both indicates your procedure is expecting two parameters called "JOB_ID" and you will get an exception if you do not define the "JOB_ID_I" argument on the query and pass in a parameter for it.
TopLink does not currently create Oracle objects such as Structs and VARRAYs for you from java objects - atleast not for stored procedures arguments, as it does not know how or what to convert them to. You will need to create the Oracle object type yourself, and pass it into the query. I have not tested it, but it would look something like:
UnitOfWork unitOfWork = getUnitOfWork();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("DSM_JOB_PKG.INSERT_JOB_RUN_LOG");
String jobId = jobIdItr.next().toString();
call.addNamedArgumentValue("JOB_ID_I", jobId);
Timestamp sysdate = BeanConvertUtil.getCurrentTimestamp();
call.addNamedArgumentValue("ORDER_DATE_I", sysdate);
call.addNamedArgumentValue("USER_ID_I", userId);
Connection con = getSession().getAccessor().getConnection();
oracle.sql.ArrayDescriptor anArrayDescriptor = new oracle.sql.ArrayDescriptor("GENERIC_STRING_TYPE",con);
oracle.sql.ARRAY anARRAYin = new ARRAY(anArrayDescriptor, con, paramTypeIds );
call.addNamedArgumentValue("JOB_PARAM_TYPE_IDS_I", anARRAYin );
oracle.sql.ARRAY anARRAYin2 = new ARRAY(anArrayDescriptor, con, paramValues);
call.addNamedArgumentValue("JOB_PARAM_VALUES_I", anARRAYin2 );
session.executeSelectingCall(call);
