ExecSQL throws NullPointerException in large jobs (Oracle)

I'm processing a loop with execSQL calls on a Oracle database. My program works fine, but after 15 minutes (= about 90 loops) it always terminates with a NullPointerException from the execSQL call. Is there any time-out for the database connection ? I have also tried to reconnect in every loop step (I know that's a terrible idea), but it doesn't work either.
I'm using Oracle 8.1.6 on Windows NT with SUN JDK 1.2.2 and the OCI drivers.
Thanks, Holger

It's costly to provide the source code, because I have this problem within the webMethods B2B Integration server which is a pure Java solution. In my scenario I use partly the special services/methods from this middleware solution to access my database tables. But anyway, I've decompiled all that crap and underneath there is the normal JDBC coding which looks fine. But I suppose it could be a problem with the Oracle settings or (more probable) the OCI drivers. I've switched to the Oracle Thin Drivers and everything works fine. But to slow !

CreateEntityManagerFactory throws NullPointerException for ejb3 jse client

This question has been posted to the Toplink/jpa forum without any reply.
Dear experts!
I am trying to create a java standard edition client, to test outside the weblogic server, my ejb 3 entities, declared as shown in the following persistence.xml.
The java code follows also. I have read about some relevant bugs in eclipselink back in 2006, or 7 or 8 and mostly unanswered threads :
CreateEntityManagerFactory null pointer exception and
Returned null to createEntityManagerFactory about tomcat and oc4j.
Persistence.createEntityManagerFactory() throw NullPointerException in oc4j
I am using JDeveloper 11g Studio Edition Version 11.1.1.3.0, Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660.
Any helping hand available?
Thank you very much in advance!

Thank you for your reply!
The client now works correctly. It seems that the line
em = emf.createEntityManager(emProps);//
throws an exception when no argument is given for em = emf.createEntityManager();// emProps missing!
There was also a warning in jdev editor, about the line you mentioned:

Carry on with your good work!

Hi,
If u goes to room directory in collaboration, there is a tab called Restricted Rooms. End of the room name there is context menu if u click that, it will show the menu there you can see the option called Request Membership. If you click that, corresponding room owner will receive the mail if he/she enabled the mail properties.
If the answer helps your Question, provide the points.

MTOM throws NullPointerException

Hello,
I need to transfer large files (12Mb) of diferent types (.pdf, .jpg, .doc, etc). I changed the return type to DataHandler and tried to enable MTOM in my webservice, but when I enabled it, after the method is executed, system throws a NullPointerException.
I'm enabling MTOM with the annotation @MTOM, and if I just take off this annotation the webservice works correctly.
Do you know of any problem using MTOM with Java 1.6.0_10? Do you have a suggestion of a better way to transfer it?
Thanks

Tested this with JDK 1.4 and it works with the following changes:
Make these static:
static public Writer out;
static public void validateXml (String xmlSt)
and, of course adding:
import java.io.*;
import org.xml.sax.*;
import javax.xml.parsers.SAXParserFactory;
Then here is what I used to test it:
public class Test2 {

Persistence.createEntityManagerFactory() throw NullPointerException in oc4j

Hi,
I am trying to use JPA(toplink essential) with EJB 2.0 spec using the DAO pattern. Outside the oc4j container all my DAO unit tests passes but when I run the same code inside oc4j the Persistence.createEntityManagerFactory() method throws a NPE. I verified that META-INF/persistence.xml file is available through the classpath inside the container but I don’t see any toplink specific logs in oc4j. Do I need to do anything to tell oc4j load up persistence.xml? I have been trying many different options in persistence.xml but I always get the same exception. Any help will be appreciated.
Code:
Persistence.createEntityManagerFactory(“default”, new HashMap());
Exception:

Crystal Report Fails on Large Jobs

Post Author: Lynn
CA Forum: Crystal Reports
We have developed user software in VB6 using Crystal 8.5. We use SQL Server for the database and a DSN for the report connection. Our problem is that when a large print job is sent to the printer, it sometimes lock up. The report we have specifically been testing prints a check and has two sub reports which print the detail invoices being paid. From some of our development machines it works fine producing 30 - 50 checks with no hitch, from others only the first 1 - 6 checks are printed and then the windows printing system hangs as well as the application. We did have a customer using the software and the driver for the printer was HP PCL6. We found that changing the driver to HP PCL5 larger data can be printed. This, however, didn't solve a client who had HP Laser Jet 4350. The PCL5 didn't change the situation. Our software has been in distribution for about three years and these print issues have only cropped up in the last few months. We have seven different databases, applications and hundreds of reports. This type of situation is occuring in all seven. We have been fighting this for a while. Please any response would be appreciated!

Hi Lynn,
Have you found a solution to this problem? We are having the exact same issue. Crystal 8.0 with a VB6 app. When the print job is being spooled it simply locks up. Sometimes you can do one or two jobs before this happens. Other times it happens right off the bat. HP LaserJet 2100 printers with PCL 5 and 6 drivers (tried both) Lee

Weblogic throws NullPointerException when using ServiceControl.setTimeout

We are invoking a SOAP service via a com.bea.control.ServiceControl that was generated from a WSDL (right click WSDL, Generate Service Control) using Weblogic 8.1.6.
SOAP service execution is successful using an http and https endpoint. However, when setting a timeout via ServiceControl.setTimeout(int millisecods) method, the Weblogic API is throwing a NullPointerException when using an https endpoint. When using an http endpoint with the setTimeout method execution is successful.

Is Oracle Enterprise Edition supports "POP3S" protocol?, Or Enterprise edition needs any additional configuration for establishing outlook connection with "pop3s" ?.
Any help is appreciated

I suspect root cause is with Java not Oracle.
Oracle RDBMS does NOT speak any "protocol" except SQL natively.

Af:inputListOfValues without values throws NullPointerException

Hello!
In some cases we have an af:inputListOfValues without any values, due to restrictions in the query. Unfortunately, a NullPointerException is thrown in this case. Actually, we are using JDev 11.1.1.5.
Is there any solution or workaround to allow empty af:inputListOfValues?
Regards,
Christoph
Edited by: mephistopheles on Sep 3, 2012 11:47 PM

Hi,
can you verify with JDeveloper 11.1.1.6 and provide a reproducible set of steps if it reproduces? Also I am wondering if the NPE is throw when you close the LOV or when you submit the form later

Edit locally throws NullPointerException

Hi All,
While doing EditLocally in a Custom Repository Manager,it throws a null pointer Exception.
As per the Repository Manager Implementation
log ,we dont any exception. So as there is no such relevent error realted to repository manager in default.trc file.
RF doesnt pass call to setContent() method of ContentManager.
We failed to do so in Nw04 SPS11 and Nw04 SPS14.
Where as we can able to edit successfully in NW04 SPS09.

Arati

Some more behavior of this problem
1)when try to edit locally>file download started and open the file in approprite application>and in the KM iview got the null pointer exception(which usually have check in now, check in later, cancel local editing buttons)
2) When resume local editing...nothing happens. Even doesnt through error in iview
3) when do a lock explicitly to any document- through selection->lock,it puts a check_out_by_me symbol rather than lock_by_me symbol
Please any body help to resolve the issue,

ODI Datastore Length differs with the DB length -IKM throws value too large

ODI datastore when reverse engineered shows different length to that of the datalength in the actual db.
ODI Datastore column details: char(44)
Target db column : varchar2(11 char)
The I$ table inserts char44 into varchar2(11char) in the target. As the source column value is empty ODI throws
"ORA-12899: value too large for column (actual: 44, maximum: 11).

Yes. I have reverse engineered the target also.
source datatype varchar2(11 char)
After Reverse Engineering
odi datstore datatype-Source : char(44)
target datatype: varchar2(11 char)
after Reverse Engineering
odi datstore datatype-Target : char(44)
Since the target datastore is char(44) in ODI Datastore and the values in the source column are null/spaces, the IKM inserts them into the target Column which is of 11 Char and the above mentioned value too large error occurs.
There are no junk values seen on the column and I tried with substr(column,1,7) and
Trim functions too and it does not help.

XMLReader throws NullPointerException

have developed a CSV to XML parser using a JAXP with SAX Events to parse the CSV file into a DOM tree.
Well inside the parse() method I have the following code":
public void parse(InputSource input) throws IOException, SAXException
BufferedReader br = null;
if( input.getCharacterStream() != null )
br = new BufferedReader( input.getCharacterStream() );
else if( input.getByteStream() != null )
br = new BufferedReader( new InputStreamReader( input.getByteStream() ) );
else if( input.getSystemId() != null )
URL url = new URL( input.getSystemId() );
br = new BufferedReader( new InputStreamReader( url.openStream() ) );
else
throw new SAXException( "Objeto InputSource invalido" );
ContentHandler ch = getContentHandler();
ch.startDocument();
ch.startElement( "", "", "file", new AttributesImpl() );
this.parseInput( br );
ch.endElement( "", "", "file" );
ch.endDocument();
Problem is that whenever the app gets to the ch.startDocument() statement it throws an java.lang.NullPointerExecption. I have no idea why this is happening, I have tested the very same code with Xalan 2 and Xercer 2 parsers and it works without problems. But using the oracle xml parser v2 throws the Exception.
Is this a bug? should I set tome of the Transformer's attributes to an specifica value to avoid this? Where could I find more info on processing SAX events?
Thanks,
Fedro

TransformerHandler throws OutOfMemoryError with large xml files

i'm using TransformerHandler to convert any content to SAX events and transform it using XSLT into an XML file.
the problem is that for large amount of content i get a OutOfMemoryError.
it seams that the content is kept in memory and only flushed when i call handler.endDocument();
i tried using auto flush writers as the Result, or call the flush() method myself, but nothing.
here is the example - pls help!
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.sax.SAXTransformerFactory;
import javax.xml.transform.sax.TransformerHandler;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.xml.sax.helpers.AttributesImpl;
public class Test
      * test handler memory usage
      * @param loops no of loops - when large enogh - OutOfMemoryError !!!
      * @param xsltFilePath xslt file
      * @param targetXmlFile output xml file
      * @throws Exception
     public static void testHandlerMemUsage(int loops, String xsltFilePath, String targetXmlFile)throws Exception
          //verify SAX support
          TransformerFactory factory = TransformerFactory.newInstance();
          if(!factory.getFeature(SAXTransformerFactory.FEATURE))
               throw new UnsupportedOperationException("SAX tranformations not supported");
          TransformerHandler handler=
               ((SAXTransformerFactory)factory).newTransformerHandler(new StreamSource(xsltFilePath));
          handler.setResult(new StreamResult(targetXmlFile));
          handler.startDocument();
          handler.startElement(null,"root","root",new AttributesImpl());
          //loop
          for(int i=0;i<loops;i++)
               handler.startElement(null,"el-"+i,"el-"+i,new AttributesImpl());
               handler.characters("value".toCharArray(),0,"value".length());
               handler.endElement(null,"el-"+i,"el-"+i);
          handler.endElement(null,"root","root");
          //System.out.println("end document");
          //only after endDocument() starts to print..
          handler.endDocument();
          //System.out.println("ended document");
     public static void main(String[] args)throws Exception
          System.out.println("--starting..");
          testHandlerMemUsage(500000,"/copy.xslt","/testHandlerMemUsage.xml");
          System.out.println("--we are still here -- increase loops..");
}

Did you try increasing memeory when starting java with the -Xmx parameter? You know that java uses only 64MB by default, so you might need to increase it to e.g. 256MB for your XML to work.
