Exception being thrown...why?

If I have
stmt = myConn.createStatement();my program works fine
But I need to be able to call rs.beforeFirst()
By default resultset is forward only...so I do
stmt = myConn.createStatement(ResultSet.TYPE_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);But I get the following exception.
Exception in thread "main" java.lang.AbstractMethodError:
org.postgresql.jdbc1.Jdbc1Connection.createStatement(II)Ljava/sql/Statement;
at GUIFrame.<init>(GUIFrame.java:28)
at TopClass.main(TopClass.java:8)

stmt =
myConn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);

Because the createStatement(int, int) method has been
around since 1.2, and you are using an earlier
driver. Upgrade your driver.

Good Luck

Thanks Lee.
Maybe you are right. I have checked what driveer we have, and it is pg73jdbc1.jar
Then I went to
http://jdbc.postgresql.org/download.html
and I notuice that this driver is for JDBC1. Is createStatement(int, int) part of JDBC 2? If so what workaround is available for me to go back in my ResultSet?
Thanks.

Why is this exception being thrown

Everytime this piece of code is run we get this Exception. Is there a way to avoid that at all. Though it is being handled properly but it would still be better if this could be avoided. Any ideas
JavaDeveloper mspete = JavaDeveloper().getInstance();
try{
mspete.setJob(new Job(goodWages));
mspete.setHouse(new House(4BDRM));
mspete.getHouse.add(Wife);
mspete.getHouse.add(Kids);
mspete.setMood(Feelin.GOOD);
catch(LayedOffDueToOffShoreDevelopmentException){
RepoMan reaper = new RepoMan();
reaper.take(mspete.getHouse());
mspete.setHouse(new House(BOX));
mspete.lose(Wife,Kids);
mspete.get(Shotgun);
mspete.shoot(mspete);

Try mspete.clone() cus that almost equals me, my error handling weren't quite as extreme though. Mine was more like
if(mspete.clone() instanceof Rob) {
Rob rob = (Rob)mspete.clone();
pub.go();
rob.drink(pub.buyLotsOfBeer());
rob.fallOverDrunk();
}Rob.

Wrong exception being thrown on CMP bean error

In OC4J Release 2 I'm getting the wrong exception thrown from a CMP bean error.
Situation:
Servlet calls an update method on a stateless session bean with trans-attribute of Required. This update method finds 2 entity beans by primary key and updates both of them (all with trans-attribute of Supports). When an error is thrown in the second entity bean (by trying to set a value to something that breaks a constraint), I get the following error:

Why am I getting a MarshallingXAException instead of a SQLException? In the old OC4J, I got a SQLException wrapped in an OrionRemoteException, with the details of what constraint was broken, instead of this.
I've also duplicated this by doing the entity bean updates directly from the servlet wrapped in a UserTransaction.
Jeff.

Tell me whether your transaction has been rolled back or not....If it has been rolled back, then those messages, printed on your server console are debug messages...just ignore them...
After this exception, can u able to execute other applications in OC4J?

REST Services - Permission exceptions being thrown

In setting up a mobile site which will make use of REST services we have started to see exceptions in the log file. These exceptions do not happen all the time - that is they are random in nature. We may see them for about an hour or so and then not see them for a day.
We are seeing the same exceptions as identified in this Re: REST secureProductCatalog exception and I used the following [Not able to invoke ATG Rest services thread|https://forums.oracle.com/forums/thread.jspa?messageID=10615221&#10615221] as a reference as well.
Working through the ATG10 document, have set up the restSecurityConfiguration.xml which identifies the beans with a secure setting of false, have set up the secureCustomCatalog.xml which identifies each of the item descriptors and the acl that is to be applied.
Have created an external user as well.
I created a simple unit test class - outside of my development environment - to simulate the remote call to the ATG server to verify the behavior. Everything passed.
Now I was able to reproduce the issue if after I establish the session (LogIn) , I log out before the call to the repository.
What I am wondering is -
1. Is there any other way in which this kind of error can be created/occurred?
2. Is there any other configuration that needs to happen?
As a side note, is there any way in which to configure REST so that it does not dump a stack trace to the log file in the event of this error - possible to create a more meaningful shorter message? When the issue happens, it just fills up the log files.

The issue turned out to be centered around the amount of connections from the mobile site to the REST service. This was verified via a load test.
Solution was to modify the mobile logic that would check if a connection/session was already open/available and use it, otherwise create a new one.
This seems to have addressed the issue

At any cost, printStackTrace should return the details of the stack, I guess it is problem with the way you are logging.Because you writing to browser outputsream and browser might be skipping most of the things
well try replace your catch with either system.out
or
catch( SQLException sqlException )
try{
java.io.PrintWriter log = new java.io.PrintWriter(new java.io.FileWriter("c:\\log.txt", false)
e.printStackTrace(log);
log.close();
}catch(ex){}
out.println( "SQLException Part 2: " + sqlException.getMessage() + "<BR>" );
toWrite = toWrite + "SQLException: " + sqlException.getMessage() + "\n" ;
catch( Exception exception )
try{
java.io.PrintWriter log = new java.io.PrintWriter(new java.io.FileWriter("c:\\log.txt", false)
e.printStackTrace(log);
log.close();
}catch(ex){}
out.println( "Exception Part 2: " + exception.getMessage() + "<BR>" );
toWrite = toWrite + "Exception: " + exception.getMessage() + "\n" ;
open c:\log.txt and just check what has printed..

Exception not thrown on Key Exists

using c# api:
I have a Btree DB configured with two secondary DB's and a custom comparer, I have initialized the DB with 'DuplicatesPolicy.NONE'. To my understanding this should cause an exception to be raised if I try to enter a duplicate. On Put(), I get no such exception.
Why? Am I supposed to throw this from comparer? (Actually tried this but it looks like it leaves cursor in undefined state). How Do I get the KeyExists Exception to be raised when a key exists???
To my understadning I cannot use PutNoDuplicate() as a primary with secondaries cannot have duplicates configured, and you can only use PutNoDuplicate if there is a sorted duplicate policy...
Any suggestions?

Hi,
The documentation could be a little misleading here. If you specify DuplicatesPolicy.NONE for a database, then duplicates will not be allowed in the database, and when trying to put a key/data pair in the database when the key already exist will fail:
"Insertion when the key of the key/data pair being inserted already exists in the database will fail. "
Failing here means that there will be no duplicate created, without any exception being thrown as the default behavior is to "Store the key/data pair in the database, replacing any previously existing key if duplicates are disallowed"; see the Database.Put() methods (BTreeDatabase extends from / is a sub-class of Database).
You should use the PutNoOverwrite method. When the key that your are trying to insert already exists in the database, you will get a KeyExistException exception.
Regards,
Andrei

Exception is being thrown

I tried out this small code for using hashset but it gives exceptions. I have no idea why is it so?

I had one more question. I am reading from the file like this

          catch(Exception e){
               e.printStackTrace();
     }Now when the end of the file is reached word contains null and throws a nullpointer exception. I am catching that exception but is there a way out that when my word is null i should simply exit out of the loop (i check that word is not equal to null in my while loop but still it throws an excpetion).Nothing there can throw NPE from word being null. The only possibilities of NPE in the code you posted are
1. if file is null
2. if wf is null
3. if NPE is being thrown inside nextWord(), which has nothing to do with word being null.
Once you make sure that the above are not happening, that code will be fine and you won't need to catch NPE. And in fact, catching NPE like that is bad practice anyway.

Exception not being thrown

I added code to throw an exception when a user-initiated search returned no rows, but for some reason, the exception isn't being raised on the browser. Code:
mnVo.setWhereClause(queryparams);
mnVo.executeQuery();
if(mnVo.first() == null)
throw new oracle.jbo.JboException("No records on file");
If I step through the code, I see the throw statement executing, but it is never surfaced. What does get raised is:
JBO-29000: Unexpected exception caught: java.lang.ArrayIndexOutOfBoundsException, msg=0
This gets raised (apprently) outside of my code, and the debugger can't find it. What do I need to have in place in order to handle this condition?

I'm a java newby, so I 'think' I understand what you mean, and I 'think' I already did? Here's the code now:
if(mnVo.first() == null)
throw new oracle.jbo.JboException("No records on file");
catch (Exception e)
{ throw new oracle.jbo.JboException("No Records Found");}
This behaves identically as it did before...I can see it being thrown in the debugger, but the browser never gets it, and it gets the other error which is pretty non-sensical to a user.
I failed to mention earlier that this code is in the Application Module in the Client Interface, in case that makes a difference?

Hi,
I think you are trying to test the Hello world EJB example shipped with the product. As a first
step I would recomend you to go through every line of the document on deploying this application,
since, I too have experienced many errors while trying to deploy the sample applications, but on
following the documentation, I subsequently overcame all the errors and have been working with the
applications. So please follow the steps in documentation and let me know, if you still encounter any
issues.
Regards
Raj

Why is exception not thrown in AseCommand when "Truncation error occurred"?

In the below SQL, data is written to SOURCE and from there to TARGET.
The DECIMAL columns in TARGET are deliberately smaller than those in SOURCE (eg a DECIMAL (12, 2) column populated from a DECIMAL (19,11) source).
When I run this in an Query tool (eg, SqlDbx) I get the messages:
"Truncation error occurred
Command has been aborted"
But when I run this using the .net Client (supplied with the Developer Edition of ASE 16.0) no exception is thrown (the INSERT fails though). The method is AseCommand.ExecuteNonQuery().
Is this deliberate?
Is this believed to be correct?
How can I tell that a truncation error has been raised?
Thanks

Hi Dave,
I am consulting internally on this. To my understanding, this behavior is based on the ASE severity level, as returned in the TDS_EED token. AseExceptions are thrown when severity level is 11 or higher.
Our docs are not explanatory in this regard. Once I get clarification we will provide something in the form of wiki or KBA or doc bug to further explain the detail. Apologize for the delay and problems this caused. I guess since the command is aborted by ASE, therefore no insertion occurs, even though ASE indicates truncation occurs prior - makes this confusing.
The message severity, etc is controlled by ASE and the client is just following suit according to the TDS spec. Its just lacking in the client docs. This can be remedied.
ASE does provide the option to allow truncation and not abort. It's a set command:
Enter a query:
1 > set arithabort numeric_truncation off
Enter a query:
1 > INSERT dbo.TARGET (S_Name_NVARCHAR,S_RedComponent_DEC_15_6,S_BlueComponent_DEC_12_2,S_GreenComponent_DEC_18_10) SELECT LEFT( S.Name_NVARCHAR,8000),S.GreenComponent_DEC,S.GreenComponent_DEC,S.GreenComponent_DEC FROM (SELECT * FROM SOURCE
) S
4 rows Affected.
Notice though ASE does NOT send truncation message. This is when it is well known and accepted to insert and truncate the numeric data.
Cheers,

InstantiationException, why being thrown?

I have several very hierarchical class (JavaBean) with a no-arg constructor. I am erring here:
// Foo extends Bar1..N all compile fine
// Foo implemnts Tee1..N
// Foo is NOT abstract NOR is declared abstract.
Object o = Foo.class.newInstance(); // throws InstantiationException
o = new Foo(); // no problem
o = new Foo().getClass().newInstance() // throws Instantiaton ExceptionI thought an Instantiation exception was thrown when attempting to instantiate an abstract class or an interface. Foo is neither. What am I missing here?

Very possibly... Thus by default upon compilation a
non-static inner class CAN be new'ed, but at runtime
of course can't be newInstance()?Lunchtime, and I tried it out ... this does seem to be your problem:
import java.lang.reflect.*;
public class NewInstanceTest
    public static void main( String argv[] )
    throws Exception
        // this fails with InstantiationException
        // Object x = Inner.class.newInstance();
        Object me = new NewInstanceTest();
        Class inner = Inner.class;
        Constructor ctor = inner.getConstructor(new Class[] {me.getClass()});
        Object y = ctor.newInstance(new Object[] {me});
    public class Inner
}To do this, you have to get the appropriate constructor. Note that if you define "inner" as a static class, the direct call to newInstance() works.

NO EXCEPTION IS THROWN FROM THE PERSIST

We are using Glassfish and MySQL. When we do a persist with a bad object/query, internal DB errors are NOT being reported back to the caller in any way, but Glassfish knows that the error occurred. Here is a schematic of the situation:
     Glassfish starts a CMP transaction and calls our bean
          Inside the bean we have code like this:
               obj = (a new object that will cause a DB error when persisted)
               try {
                    entityManager.persist(obj)
               } catch (Throwable t) {
                    report to the user that the throwable happened
          bean returns
     Glassfish manages CMP transaction
What we see is the following:
     - The persist has an internal failure and generates error messages in the Glassfish system.log file.
     - NO EXCEPTION IS THROWN FROM THE PERSIST, so the application code thinks that the persist completed correctly
     - At the end of the bean operation, Glassfish (correctly) rolls back the transaction.
At the user level the result is that the request succeeds but nothing is put into the Database!
We are not asking about the cause of the DB error. From reading the system log we know what happened and can fix it. Our problem is that problems in our field-deployed systems cannot be detected by the application code so failures cannot be reported to the user.
The critical question is:
     Is there a way for the application code in the bean to see that an error occurred?
By the way, we also have a secondary question: Why is the erroneous persist tried 6 times before deciding it won't work? Is there an option somewhere that says to try 6 times?
The Exception as reported in the system log (only one copy of it) is included below.

This is because the persistent context is not synchronized with the database until the commit is being executed.
You might 'force' this by calling entityManager.flush() right after the call to persist(...).
Or you register a transaction synchronizer and check the transaction status on afeterCompletion().

Exception is thrown but exception.getMessage() is null

Hi,
I am wirting a code in which an exception is thrown, I catch this exception in the catch block, but when I display e.getMessage() it displays null.....Can any body help in telling why....
Thanks
Rajnish Verma

getMessage() is just about useless. If you use the no-arg constructor for a Throwable, you'll get a null message. Much, much better for displaying information about Throwables is toString() which will include the class name of the Throwable and the message if it's not null. Out shop never uses getMessage()

Exception is thrown only while executing the jar file

java.lang.NoClassDefFoundError: javax/mail/Address Exception is thrown only while executing the jar file. But the program compiles and executes good when executed for command prompt through the class files.
I used javamail API in my program. Classpath and every others are set to the right one's. Executed fine when used java Random.class. But the problem is only with the jar file.
Please help me out in this regard. Why the exception is thrown only in jar but not at class level.

Assuming you're running your program using "java -jar", your jar file needs a Class-Path entry
in the manifest file that references mail.jar.

Populating OUT parameters when TOO_MANY_ROWS exception is thrown

When I was trying to write code to test out today's PL/SQL challenge quiz, the behavior appears to depend on the table being queried. I can't figure out what attribute of the table drives the behavior (or if there is a different explanation for the behavior).
The quiz is testing what happens when a procedure does a SELECT INTO an OUT parameter and a TOO_MANY_ROWS exception is thrown. The intent is to show that even though the behavior is technically undefined, what actually happens is that the OUT parameter is populated with the first row that is selected (obviously, you would never write code that depends on this behavior-- this is solely an academic exercise). The demonstration code works as expected
CREATE TABLE plch_emp ( emp_name VARCHAR2(100) );
INSERT INTO plch_emp VALUES ('Jones');
INSERT INTO plch_emp VALUES ('Smith');
COMMIT;
CREATE OR REPLACE PROCEDURE plch_get
(out_name OUT plch_emp.emp_name%TYPE) IS
BEGIN
SELECT emp_name
INTO out_name
FROM plch_emp
ORDER BY emp_name;
EXCEPTION
WHEN OTHERS THEN
    dbms_output.put_line('A:' || out_name);
END;
What will be displayed after executing the following block:
DECLARE
l_name plch_emp.emp_name%TYPE;
BEGIN
plch_get(l_name);
dbms_output.put_line('B:' || l_name);
END;
/and outputs
A:Jones
B:JonesWhen I replicate the logic while hitting the EMP table, the PLCH_EMP table, and the newly created EMP2 table, however, I get different behavior for the EMP and EMP2 tables. The procedure that queries PLCH_EMP works as expected but the OUT parameter is NULL when either EMP or EMP2 are created. Any idea what causes the behavior to differ?

Your test was done as a single anonymous PL/SQL block. Which means each proc that was called referenced the same variable/memory - are there perhaps PL/SQL optimisation enabled for the database or session? Or any other settings that could influence the test? Have you tried calling the procedures directly from SQL*Plus using a bind var and not via an anon block and a local var in that block?I have.

As a sanity test - what happens when proc P3 for example is changed to a catersian join/union of emp2 and plch_emp? Do the test results change? Or you can change it as follows:

Of course, you can also put this one down to using an operating system like Windows as a poor database server and not as a magnificent client gaming platform... Well, sure. But you can probably only play World of Warcraft so long before you need to write some PL/SQL.
