Problem Encountering in oracle.sql.ARRAY type

Hi,
i am using one stored procedure to get a set of records.
i am getting it by mapping those things with java.sql.Array. And after that i am getting the values as ResultSet from that Array. The same thing is working fine in Windows platform. If i posted those thing into Unix - AIX, i am facing an ArrayIndexOutofBoundsException while getting ResultSet from oracle.sql.ARRAY class. I checked out ARRAY instance.it is not null. Both Application and Database are same except O.S.
Can Anybody help me. I need it imm.
Thanks in Advance
Regards
Eswaramoorthy.G

Hi
Did you ever figure out what the problem was with this? We have a client that is experiencing the same problem on AIX but we cannot reproduce using their database running under NT nor Sun. Any information would be appreciated. You can respond directly to [email protected]
Thanks in adavance

Looking at the ARRAY.toBytes() method:
public byte[] toBytes()
throws SQLException
synchronized (getInternalConnection())
return this.descriptor.toBytes(this, this.enableBuffering);
..., it synchronizes on the following method (getInternalConnection() -> getPhysicalConnection()):
oracle.jdbc.internal.OracleConnection getPhysicalConnection()
if (this.physicalConnection == null)
try
this.physicalConnection = ((oracle.jdbc.internal.OracleConnection)new OracleDriver().defaultConnection());
catch (SQLException localSQLException)
return this.physicalConnection;
defaultConnection() does the following:
public Connection defaultConnection()
throws SQLException
if ((defaultConn == null) || (defaultConn.isClosed()))
synchronized (OracleDriver.class)
if ((defaultConn == null) || (defaultConn.isClosed()))
defaultConn = connect("jdbc:oracle:kprb:", new Properties());
return defaultConn;
So there's synchronizations on the connection instance and OracleDriver.class object... I can't see how this can deadlock. To get to the point of needing the lock on OracleDriver.class, the thread would already have the lock on the connection instance.... clearly I'm missing something.
Thanks

Welcome to the forum. If you want help, at least try to think where to post a question and look for a forum that matches the topic. Lets examine what you have:
- its Weblogic, so if you would ask a non-programming related question anywhere it would be in the Weblogic forum
- HOWEVER, if you check the top of the stacktrace, you'll see that the problem stems from the JDBC driver, so a JDBC related forum would be a closer match
For future reference, Weblogic specific questions should go here: https://forums.oracle.com/forums/category.jspa?categoryID=193
and JDBC/OJDBC driver related questions should go here: Java Database Connectivity (JDBC)
Final tip: use \ tags to post code so it is readable.

Problem passing oracle.sql.ARRAY to Oracle

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.

Java.sql.SQLException: Internal Error with oracle.sql.ARRAY getArray()

hi,
I am having having problems with the getArray() of oracle.sql.ARRAY.
Here are the details:
Oracle Database - 9.2.0.6. The JDBC driver used -10.2.0.1 jar.(the latest available).
I am calling a stored procedure from java, that has out param as a collection (VARRAY) of a user defined type.
The stored procedure works fine, if the user/schema used to connect,contains actual type, and i am able to extract the user defined object from the oracle.sql.ARRAY, via getArray().
But if i use a different user to connect which has public synonyms and execute rights to the actual type, i get the following error:
java.sql.SQLException: Internal Error

     at oracle.sql.ARRAY.getArray(ARRAY.java:370)
The problem is happening because we have 2 different users to connect to the database. one is the dba user, which contains all the types, packages and other one the application user, which we are supposed to use, to connect via java. This application user does have access to types via public synonym, but it gives the above mentioned error.
Please help :(.
Regards,
Gaurav.

Hi avi,
Even I am getting the same error inspite of preceding the type name with the same user who has created the type.
It has displayed the array length.When I am trying to fetch each array, I am getting the error.
ARRAY simpleArray = (ARRAY) cs.getObject(3);
System.out.println("Array is of length " + simpleArray.length());          ********************** The above stmt prints 2 records ******************
But it goes to exception in the foll stmt..
Object [] objArrStructArray = null;
try{
     objArrStructArray = (Object[]) simpleArray.getArray();
}catch(SQLException e){
     e.printStackTrace();
Do u know abt this?
The foll is the error which I am getting.

How to create oracle.sql.array

I need to create an oracle.sql.array to pass in my custom objects array to the database. I know you can create it using the ArrayDescriptor class but the problem with that is the connection object is need.
I am using the writeSql() method of the SQLData interface. I therefore dont have the connection object. Any ideas?

haha
you misunderstand. i have in my code:
<code>
 // update the organisation
 public boolean setOrganisation(Organisation pOrg) {
 Organisation org = pOrg;
 OracleCallableStatement callStat = null;
 Connection conn = null;
 boolean OK = false;
 try {
 conn = getConnection(getUserName());
 pOrg.setConnection(conn);
 callStat = (OracleCallableStatement) conn.prepareCall("{call p_cmt.update_organisation(?)}");
 callStat.setObject(1, org);
 callStat.execute();
 OK = true;
 } catch (Exception e) {
 logger.severe("error writing organisation with id " + org.getId() + ". " + e);
 } finally {
 cleanUpConnections(conn, callStat);
 return OK;
</code>
This writes the object organisation to the database. Now in the class organisation i have the following method which is called automatically when writing the organisation object to the database:
<code>
 public void writeSQL(SQLOutput p_stream) throws SQLException {
 p_stream.writeInt(id);
 p_stream.writeObject(country);
 if (finIndexArr == null)
 finIndexArr = new ListElement[0];
 ArrayDescriptor af = ArrayDescriptor.createDescriptor(
 ObjectMapper.elementList, conn);
 ARRAY arr = new ARRAY(af, conn, finIndexArr);
 p_stream.writeArray(arr);
</code>
The problem is the last bit. To put the finIndexArr into an array i need the connection object. So i have to pass into the organisation object the connection object which seems unneccessary and pointless to me. I was just looking at an alternative way of creating the array without the need of the connection object. Since the setOrganisation() above has the connection to the database i dont see why i need to specify it in the array as well

Java.sql.SQLException: Internal Error while using oracle.sql.ARRAY.getArray

Hello All,
Here is the issue description. Our application uses Oracle Object Types and LIST. We deployed our application on QA environment which has Oracle 10g. Application runs fine...no issues. Now we moved to UAT. UAT environment is same as QA environment and DBA have created replica of QA database.
Now WAR file which works fine with QA database , somehow doesnt work with UAT database. Application throws following exception when code tries to call getArray() on java.sql.Array.
We tried to point UAT weblogic to QA database and it worked fine.....but when we point UAT weblogic to UAT database , we get following exception. So we know that this is a database issue.
DBA claims that QA env database and UAT env database are same.
Can anybody please tell me what wrong here? What setting is not done on UAT database which is done on QA?

This can happen if you use the oracle.sql.ARRAY class with WebLogic.
WebLogic wraps oracle.sql.ARRAY with its own class (i.e. weblogic.jdbc.wrapper.Array_oracle_sql_ARRAY). The easiest solution is to replace oracle.sql.ARRAY with the JDBC standard java.sql.Array.
<PRE class=jive-pre><CODE class="jive-code jive-java">Object[] items = (Object[])array.getArray();
if (items.length > 0) {
for (int i = 0; i < items.length; i++) {
Object arrayItem = items;
}
}
</CODE></PRE>
The array object is a java.sql.Array. Here no unwrapping of the WebLogic wrapper is needed.
If you absolutely need the oracle.sql.ARRAY class than you must use an unwrap API on the WebLogic wrapper class.
<PRE class=jive-pre><CODE class="jive-code jive-java">if (object instanceof weblogic.jdbc.wrapper.Array)
array = (ARRAY) ( ((weblogic.jdbc.wrapper.Array)object).unwrap(Class.forName("oracle.sql.ARRAY")) );
else
array = (ARRAY) object;
</CODE></PRE>
Here, array is an oracle.sql.ARRAY. Try to see if this <A class=bodylinkwhite href="http://www.software-to-convert.com/3gp-conversion-software/3gp-to-myspace-video-software.html">helps</A>. Good luck.
Thanks for your explanation! It's very valuable, It is exactly what I need, I understand this part.

If i use cs.registerOutParameter(4, Types.ARRAY, "SCHEMA_OWNER_NAME.ISSUESECTION_LIST"); Then i wont be getting the error.
COULD ANYONE LET ME KNOW THE WORK AROUND OTHER THAN THE ABOVE SOLUTION LIKE ADDING THE OWNER SCHEMA NAME WITH THE USER DEFINED COLLECTION TYPE.

There couold be two reasons:
1) it depends how u have defined type. if ISSUESECTION_LIST is defined in type SCHEMA_OWNER, then you have to call this ways only 'SCHEMA_OWNER_NAME.ISSUESECTION_LIST'
2) You might have defined using schema_owner_name like scott.<TYPE_NAME>. if its so, then drop it and again define type without using schema owner.
For detail help post your type declaration.

NullPointer from constructor of oracle.sql.ARRAY

This is a strange one, I'm hoping someone has seen this before.
I'm seeing a nullpointer exception from the contructor of ARRAY(ArrayDescriptor, Connection, Object)
This occurs when I'm trying to make a call from an application module to a stored procedure with custom database types.
This seems to work fine in the embedded OC4J instance but fails when deployed to an application server on linux. The version is 10.1.2.
thanks for your help.

Avi, thanks for your response. The connection is obtained from a BC4J appmod, which ultimately comes from a pooled datasource.
When I look at the implementation class in the embeded OC4J environment it is com.evermind.sql.OracleConnectionBCELProxy__com_evermind_sql_OrionCMTConnection__SQLBCELProxy. The call to ARRAY works in this environment.
On the application server the runtime implementation of the connection is com.evermind.sql.ConnectionBCELProxy__com_evermind_sql_OrionCMTConnectionFinalize__SQLBCELProxy. This fails with the exception in the original post.
In both environments I can successfuly cast to an OracleConnection so I'm pretty sure both implementaion classes are subclasses of OracleConnection.
Both environments are 10.1.2.
thanks for your help so far.

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.

Conversion of java Array to oracle SQL Array while calling Stored Procedure

How java Array can be converted to oracle SQL array while calling Stored procedure with callable statement.
i.e java Array ---> Sql Array in Oracle while setting the datatypes to callable statement arguments.

Oracle defined array type

Hi,
I am trying to pass an input parameter to a stored procedure as oracle defined array type. The input parameter will be stored as an array_varchar type which is defined by our own in our oracle 9i. Can anyone tell me how ? I've been looking for solution for 2 days and still dont know how.
Thanks.
yves

The solution described in Passing Array of UDT or Collection as IN OUT using OracleDbType.InputOutput
is working for me.

Problem in adding "TableLayoutPanel" control array type functionality on windows form dynamically using drag and drop

Environment: -
(Application Machine)
OS Name : -
Microsoft Windows 7 Professional/XP SP2/SP3
OS Bit Version : -
32 Bit
Application Name: - Designer.exe
IDE
: - Visual Studio 2008
EXE Application development: -
VB. Net
Application Type: -
Application “Designer.exe” was designed in vb6.0 and now, it has been upgraded to Visual Studio 2008 and it works properly.
Product Description: -
 We have an application Designer.exe, which is used for designing “Forms”.
It has menu option with following option like Panel, Text Box, Combo Box, Button etc. We drag any of this menu items and place it to form.
Requirement: -
We have
critical requirement in product. In Designer.exe, we need to align form margin, while we increase or decrease window. And for that we have searched that
“TableLayoutPanel” components can be helpful.
Problem description: -
Earlier code was in vb6.0, now it has upgraded to Visual Studio 2008. In vb6.0, we have used control array for memory utilization with Combo Box, Group Box, and Text
Box etc.
But, for alignment we have to use “TableLayoutPanel”
control array type functionality on form.
Code Snippet: - For earlier designing component e.g. Frame
'Required by the Windows Form Designer
Public WithEvents Frame1 As Microsoft.VisualBasic.Compatibility.VB6.GroupBoxArray
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
Me.components = New System.ComponentModel.Container
Me.Frame1 = New Microsoft.VisualBasic.Compatibility.VB6.GroupBoxArray(Me.components)
CType(Me.Frame1, System.ComponentModel.ISupportInitialize).BeginInit()
. Kindly suggest approach for implementing requirement.
Kindly help us to complete the requirement. I will be really
thankful for any assistance.

Problem while using oracle.sql.CLOB

Hello,
I was trying to use oracle.sql.CLOB to update CLOB types in database. I was able to successfully run the update when I use the connection obtained from normal DriverManager.getConnection method. But have issues when I use a datasource lookup, Am using Websphere as my JDBC provider environ.
The exception I get during the execution of this line is
oracle.sql.CLOB newClob = oracle.sql.CLOB.createTemporary((java.sql.Connection)conn, false, oracle.sql.CLOB.DURATION_CALL);
java.lang.ClassCastException: com.ibm.ws.rsadapter.jdbc.WSJdbcConnection
as my connection is obtained by DataSource.getConnection() method.
Is this a documented limitation of Oracle SQL CLOB class or is there a way I can tweak the code to work.
Am using a oracle 9i thin driver
Thanks

With the new Oracle drivers there is no need to do it that complicated.
Finally Oracle has implemented the standard JDBC calls, and inserting a CLOB is really easy now:
String clobContent = populateClobData(); // whatever...
stmt = con.prepareStatement("INSERT INTO clob_table (id, clob_col) VALUES (?,?)";
stmt.setInt(1, 42);
Reader r = new StringReader(clobContent);
stmt.setCharacterStream(2, r, clobContent.length());
stmt.executeUpdate();
con.commit();This works with UPDATE as well. If you need to deal with BLOBs simply use setBinaryStream().
Reading is done using getCharacterStream() or getBinaryStream()
This actually works across all (or at leas all major) database systems
