ROUND_UNNECESSARY - java.lang.ArithmeticException: Rounding necessary
I am doing a BigDecimal.divide with ROUND_UNNECESSARY as my rounding mode - this is because I want the real number returned to me so that I can use my own customized rounding method. How can I accomplish this without rounding? By the way, the operation can have any real number as numerator and denominator

What would be the value of the BigDecimal if no rounding was performed and you were dividing 1 by 3?
Could you maybe round to some huge number of decimal places and then use your routine on that result?

at weblogic.work.ExecuteThread.run(ExecuteThread.java:178)It is possible Java 1.3 was not so perdantic. ALso it is easy to write prgrams with bugs in them which just happen to work the way they are used. Doing things a little differently reveals the bug.
The problem comes from the use of new BigDecimal(double). This gives a faithful reproduction of the underlying double value. Many methods which convert double to another type allow for a small rounding error in the double, this constructor does not.
Even a simple value like 0.1 has a small rounding error for double type. Normally this is not obvious, with BigDecimal it is.
double d = 0.1;
System.out.println("d= " + Double.toString(d));
BigDecimal bd = new BigDecimal(d);
System.out.println("bd= " + bd);
BigDecimal bd2 = BigDecimal.valueOf(d);
System.out.println("bd2= " + bd2);prints
d= 0.1
bd= 0.1000000000000000055511151231257827021181583404541015625
bd2= 0.1As you can see the second method for converting a double doesn't have this round issue for this value. This might be a temping option and it might work most of the time, however using setScale() with a rounding option will work every time. -
OCI, java.lang.ArithmeticException: / by zero

Could someone help me with this?
I'm using OCI driver, because database character set is user-defined.
There is no problem with connection, but if I open any database objects list or execute any statement I've got this exception:

I dig into JVM using VisualVM and find out that oracle.jdbc.driver.T2CConnection.conversion (DBConversion.java) has property sMaxCharSize=0.
When I'm connecting to other DB (wihtout user defined charset) this property has value 1 and everything is ok.
Other DB tools like Squirell SQL, PL/SQL Developer works fine so maybe there is a bug in Oracle SQL Developer?.This seems more like a bug in the JDBC driver than in SQL Developer itself.
Try replacing the JDBC driver in SQLDEVELOPER_INSTALL_DIR\jdbc\lib with the very latest version from OTN.
You may also want to try upgrading your OCI client to latest and if you still got the problem then better raise a SR on Metalink/MOS if you have a DB support contract. -

Financial Reporting Exception - Error executing query: java.lang.Arithmetic
Hi all,
I'm using the Financial Reporting Studio 11.1.2.507 to develop a report to a planning application, so i'm using a planning connection to do it. This report involves some calcs and i have sure that is possible generate a divide by zero. But what happen is: I started developing this report using the user admin and no error message was shown. Then when i tryed to acess this report with a user other than the admin user the error occurs: "Error executing query: java.lang.ArithmeticException: / by zerojava.lang.ArithmeticException".
So, have you seen this scenario before?
Could you help me with this issue?
p.s: if i wasn't clear enough, please tell me!
Warm regards,
Rafael Melo - BrasilMehmet,
Thanks a lot for your quick response. The error message appears when i acess through the workspace. When I was developing I was acessing with admin user (FR Studio) and now I'm using other user to test the report in the workspace. I've commited a mistake when i thought that the user point of view that I defined when i was developing would be applied over all users. So, when I opened the report with a user other than the admin the error ocurred because the default attributes resulted in a empty resultset or something like that.
Is there a way to define a user point of view (pov) for all user at once?
Best Regards,
Rafael Melo -

The bold part says that line 37 of the Main class did something bad. It's in the doSomethingBad method.
I'm not sure what you mean by auto number, that's not something inherent to PreparedStatement and the only reason your posted code would throw an ArrayIndexOutOfBoundsException is because field 6 doesn't exist when you call setDouble(6, quantity). I figure that's because you accidently skipped 2. -
Getting java.lang.NullpointerException while closing resultset aft using it
Hi,
I kindly request to share your ideas reg. my problem.
I am opening a database connection using connection pool and i am using two or more resultsets and statement objects.I am closing these objects at the end of their usage.But i am getting java.lang.NullpointerException when i close them(if i don't close them it works fine). what might be the reason.

Also plz help me to improve the code if necessary so that it will work fine for multiple users
thaks & regards
Prasanth.CThanks a lot.
i replaced the code below
if (rs != null)
try
rs.close();
catch (SQLException e)
rs = null;
if (rs1 != null)
try
rs1.close();
catch (SQLException e)
rs1 = null;
if (rs2 != null)
try
rs2.close();
catch (SQLException e)
rs2 = null;
if (rs3 != null)
try
rs3.close();
catch (SQLException e)
rs3 = null;
if (st != null)
try
st.close();
catch (SQLException e)
st = null;
if (pst != null)
try
pst.close();
catch (SQLException e)
pst = null;
instead of blindly closing the resultsets and statements
now it works fine.
One more thing, is my code structurally correct, i mean the variables, try...catch blocks,results,statements,database connections and overall coding. whether it looks like professional code.
thaks & regards,

Data Federator Connection to R3 - java.lang.NullPointerException
Hi.
We are trying to add a SAP R3 DataSource in Data Federator XI 3.0 SP2.
Test Connection gives us the following message: "The connection was established but there is no table for the given connection parameters", what it seems to be ok according to the SAP doc.
However, when we try to get a list of the Functions or Infosets in the SAP system, an error comes because of a "java.lang.NullPointerException". Checking the application log we get the following:
2010/03/30 12:21:27.059|<=|||0|26537104| |||||||||||||||"[LeSelect.Api.LSStatementImpl] - [Execution Thread 4]Executing query: CALL executeConnectorCommand '/TEST//TEST/user_bla/sources/draft/R3SYS', 'GET_FUNCTION_LIST * * 200'"

We registered the callback program and did all of the steps indicated for the installation, also checked the possible sources of the error according to OSS Note 1278491.
Any idea how to solve this? Thanks.Hello, we have the similar problem: while connecting from Data Federator to SAP ERP we get the following error - "Wrapper /ZTEST/sources/ZTEST reported an exception which is not a WrapperException: java.lang.NullPointerException: null"
It's necessary to install "SAP BusinessObjects Data Federator Infoset, SAP Query and ABAP Functions Connector Prototype"
SAP BusinessObjects Web Intelligence Reporting for SAP ERP
for connection to SAP ERP.
Are there any ideas? Thanks -

} Please tel me where is my mistake or maybe you knew another way to open JInternalFrame with public method form another classSome possibly helpful suggestions:
1) Create one JDesktopPane, and do it in the constructor of GUI. You should call this constructor only once.
2) Get rid of GUII. The GUI constructor will do all this and more.
3) Get rid of startFrame and startFrame2.
4) In GUI2, change your width and height to static variables if you are going to use them in outside classes. There is no reason to have to create a GUI2 object just to get those values. Get them from the class, not the instances.
5) You're doing something funky in your Top class with your mixing of static code and non-static code. My gut tells me that Top is just a static universe that exists to get your code up and running, and that the code within it should all be static, but that's just my personal opinion.
6) In MyInternalFrame, get the height and width from GUI2 (if that's what you want to do) again in a static fashion. Rather than new GUI2().width which makes no sense, use GUI2.width.
Why can't you put the button inside of the JInternalFrame object? I believe that the contentPane of this object which may hold your button (unless you embed a jpanel) uses BorderLayout, so you have to take care how you add jcomponents to the jinternalframe (or more precisely, it's contentPane). -
Java.lang.NoClassDefFoundError while calling a java class from BPEL
Hi,
I'm calling a java class to convert JSON to XML using BPEL. I have imported all the necessary jar files in the project and compiling done successfully.
But at runtime , i get the java.lang.NoClassDefFoundError: net/sf/json/JSON error.
For this i placed all the necessary jars under FUSION_HOME/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1/ path and restarted the server.
But still i'm getting the same error at runtime.
Did i missed any step? Let me know the procedure to solve this.
Do i have to run ant or edit Manifest file after placing the jar?
in one site i find we have to place the jars under <DOMAIN HOME>/lib directory. Is this correct?
We are using SOA suite 11.1.1.6.
Thanks,
TerryHi Karan,
I have done placing the jars at FUSION_HOME/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1/ and ran ant -f build.xml .The build was successful without any error.
I have even placed the jars in <DOMAIN HOME>/lib (/us2001/fmw/11.1.1.6/user_projects/domains/ohsdomain/lib) and did a server restart.
After these activities, when i execute the composite, i still get the error in em console,
Message
got RuntimeException

Any Help will be appreciated. Thank you.sounds like your deployment isn't right - either your classpath isn't set correctly or you haven't included all the classes necessary in your deployment - or if this was working but now it's not then perhaps you removed something?

Java.lang.VerifyError - Incompatible object argument for function call
Hi all,
I'm developing a JSP application (powered by Tomcat 4.0.1 in JDK 1.3, in Eclipse 3.3). Among other stuff I have 3 classes interacting with an Oracle database, covering 3 use cases - renaming, adding and deleting an database object. The renaming class simply updates the database with a String variable it receives from the request object, whereas the other two classes perform some calculations with the request data and update the database accordingly.
When the adding or deleting classes are executed, by performing the appropriate actions through the web application, Tomcat throws the following:
java.lang.VerifyError: (class: action/GliederungNewAction, method: insertNewNode signature: (Loracle/jdbc/driver/OracleConnection;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V) Incompatible object argument for function call

...The renaming works fine though. I have checked mailing lists and forums as well as contacted the company's java support but everything I have tried out so far, from exchanging the xerces.jar files found in JDOM and Tomcat to rebuidling the project didn't help.
I just can't explain to myself why this error occurs and I don't see how some additional Java code in the other 2 classes could cause it?
I realize that the Tomcat and JDK versions I'm using are totally out of date, but that's company's current standard and I can't really change that.
Here's the source code. I moved parts of the business logic from Java to Oracle recently but I left the SQL statements that the Oracle stored procedures are executing if it helps someone.

}After further googling I figured out what was causing the problem: in eclipse I was referring to external libraries located in eclipse/plugins directory, whereas Tomcat was referring to the same libraries (possibly older versions) in it's common/lib directory.

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
Hello everyone ... sorry for my English but I am an Italian boy with a problem that is not answered.
I had to create a web application-service (created in Java with NetBeans 6.7) which is connected to a database postgresql (8.3.5) and for connection to the server using tomcat (3.2.4) through SOAP messages (2_2).
OPERATING SYSTEM: WINXP
I have created classes ... I created the database ... completed the project in NetBeans without any errors ... implemented the necessary libraries in the project (also ).... 8.3.604.jar jdbc tomcat configured and soap ... .. and set the environment variables (soap, mail, send in xerces )...... run the application on the NetBeans appears the login screen of my web service .....
enter username and password (exactly!) and the NetBeans gives me an Exception:

} The strange thing is that this web service was running just finished the project.
After 4-5 days of its operation has stopped, creandomi this problem.
I think the answer is, the server that is not the case.
I thought all I thought was jdbc, but I can connect to the database, so I do not know what to do and how to proceed.
thanks to all, and thanks to my translator. :PParameter par = respons.getReturnValue();There is only one possible reason, "respons" is null.
