Oracle.sql.Opaque

Hi, I am using the JDBC drivers for Oracle 8.1.7 (classes12.zip ( 1,892 kB)) and when i am trying to generate xml using XDK (xdk_java_9_2_0_5_0.zip). If i use methods like insertXML or OracleXMLSave it throws me an exception: Exception in thread "main" java.lang.NoClassDefFoundError: oracle/sql/OPAQUE.
Then I use the driver for 9i (classes12.zip (1,143,559 bytes)) and it works fine, but I want to know what am I doing wrong, because my base document is Oracle 8i Application Developer’s Guide - XML. And I think these drivers have to work.
Another issue, thinking about performance and throughput, what driver should i use if my bd is 8.1.7, is it better to work with the specific version or the lastest?
Thanks

I believe the 9.2 XDK requires the use of the 9.2 JDBC drivers.
In general, later versions of the JDBC driver will work with older versions of the database, but not vice versa. The 8.1.7 JDBC drivers won't necessarily work with a 9.2 database, but the 9.2 JDBC drivers will work with an 8.1.7 database.

Hello,
from the little information in your post i would say try to import oracle.sql.*, oracle.jdbc.* and oracle.xdb.*. Make sure your project can access the following libraries ojdbc14.jar and xdb.jar.

NoClassDefFoundError: oracle/sql/OPAQUE

I've got some configuration problem with the XSU utility. It runs the getXML with all these settings fine. But when I run the putXML I get this result:
C:\Documents and Settings\kstclair>java OracleXML putXML -user "jandj/xprojxabc" -conn "jdbc:oracle:thin:@10.1.10.11:1521:UNIT1" -fileName "/testXML/transformed.goodusers.xml" user_data

Anybody seen this and know what it means? I've looked in most of the jars and can't even find this package sequence.

Oops. I don't know if I missed in the doco, or if it's not there. If you use Oracle 8.1.7, then don't use the xsu12.jar. It will seem to work, and will even respond to getXML commands. But apparently you need to use the xsu12_817.jar instead. Most of the doco and examples are written for 9i users, so this point gets missed.

NoClassDefFound error oracle/sql/opaque

Hi There,
[Using Java 1.4.2, BEA WebLogic 8.1, Oracle 9i Db]
We're having a bit of trouble with the above error.
In our java code, we are referencing xdb.jar and odbc14.jar but when we try to create an XMLTYPE object from an OPAQUE object we receive the NoClassDefFound error.
Anyone with any ideas on how to get around this please?
Many thanks,
Neil

Hi,
I had the same problem...
Put the xsu12_817.jar or xsu12_816.jar (depends on RDBMS version) in your CLASSPATH instead of xsu12.jar. (you can find xsu12_817.jar and xsu12_816.jar files in Oracle XDK).
It should work.

Sash

I've searched but really found nothing indicating problems with this class. Is this an NLS problem?

Well - I don't have to look for that setting - I know it's set to excatly that - because I did that ;)
I cannot use the JDBC built into OC4J. First, it's using CLASSES12DMS - secondly I use XDB. Even if it was using OJDBC14 it most likely would not be "binary compatible" with the XDB from the 10g RDBMS. I've had this problem on the AS 10g of OC4J and I did try it on this one too. XDB crashes out with basically the same error -just different library.
My issue is integration into OC4J. This application works outside OC4J (the method that fails work). By simply setting CLASSPATH to the OJDBC14 from the instant client, LD_LIBRARY_PATH to the *.so files from the same instant client, plus XDB from the 10g home, and XMLPARSEV2 - the connection succeeds and data is retreived etc.
NOW - the exact error here I think I identified. OC4J loads ORAI18N - an older version (at least different from) compared to the one that comes with instant client. I put the instant client's ORAI18N in the "pre-path" load (that setting you refer to) and I'm now at a different loader constraint for sql/oracle/OPAQUE. Trying to identify which library, if any, that OC4J is providing which shouldn't be there.
I've read the note that explains how to install a different version of JDBC with OC4J. Problem is, that instant client doesn't come with CLASSES12DMS - and secondly I've tried to replace the DMS version with a link to OJDBC14 and it staill failed.
In a way this particular thread got resolved last night - but I still have the same basicly problem. Getting a different JDCB version using OCI to work from within OC4J 10.1.x.

Copying from Oracle SQL Developer to Microsoft Word doesn't retain formatting (Font,colors etc)

Copying from Oracle SQL Developer Worksheet doesn't retain formatting (font,color etc...)in Microsoft Word but copying from other programs such as
visual studio, chrome browser etc works fine. This doesn't work even after changed the setting to Keep Source formatting of Options-> Copy and Paste Settings

Hi,
I notice that you have cross posted in Answers forum and Oracle forum. Have you tried Mr. Peter's suggestion?
Then, I recommend we check the Word settings:
1. Go to: Options > Advanced > Cut, Copy and Paste
2. Make sure that Use smart cut and paste is ticked.
3. Click the Settings button next to this option
4. Make sure that Smart Style
Behavior is checked.
If the issue still exists, please upload a sample through One Drive, I want to test.

Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
An error was encountered performing the required operation Got a minus one from read call .Vendor code 0
However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.

Thanks for your patience and help in advance.

Problem with java.sql.Clob and oracle.sql.CLOB

Hi,
I am using oracle9i and SAP web application server. I am getClob method and storing that in java.sql.Clob and using the getClass().getName() I am getting the class name as oracle.sql.CLOB. But when I am trying to cast this to oracle.sql.CLOB i am getting ClassCastException. The code is given below
java.sql.Clob lOracleClob = lResultSet.getClob(lColIndex + 1);
lPrintWriter = new PrintWriter(new BufferedWriter (((oracle.sql.CLOB) lOracleClob).getCharacterOutputStream()));
lResourceStatus = true;
can anybody please tell me the what is the problem with this and solution.
thanks,
Ashok.

Hi Ashok
You can get a "ClassCastException" when the JVM doesn't have access to the specific class (in your case, "oracle.sql.CLOB").
Just check your classpath and see if you are referring to the correct jar files.

Oracle SQL Developer error - "The file-based source procedure Name is not present in the database."

I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name> is not present in the database. Was it compiled?'
instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

Sounds like you do not have the correct privileges. What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest? If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
The role SELECT_CATALOG_ROLE
The system privilege SELECT ANY DICTIONARY
And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
The role EXECUTE_CATALOG_ROLE
The system privilege EXECUTE ANY PROCEDURE
Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
Best wishes,
Gary

Can we use different Databases (Oracle & SQL Server) in one report?

Post Author: venki5star
CA Forum: .NET
Hi there.
Can we use different databases (Oracle & SQL Server) in a same report?
If possible how?
Another question,
Can we change the Provider Name at runtime of the given report. If so the above question is useless...
Thanks in Advance.

I tried this using Oracle Provider for OLEDB (the one that supplied by Oracle Client) and Crystal Reports 9. you can drag the column into designer but the image does not appear in preview.
I guess it's because CR does not recognized it as image, and there are no information that the blob data is an image at all.
