• java.lang.UnsupportedClassVersionError and Java versions

  Hello-

  I have provided some of our users with a pot that I compiled with Java 1.6. The jar consists of a single class. Users to run Java 7.  However, some of them receive this error:

  java.lang.UnsupportedClassVersionError: bad version major < class > offset = 6

  
  

  So, I checked the following:

  
  

  - java - verbose indicates the class has been compiled with Java 6:
  

  minor version: 0

  major version: 50

  - java-version indicates the user is running a newer version of java:

  1.7.0_67

  -the jar manifest States the following:

  Created by: 20.13 - b02 (Sun Microsystems Inc.)

  As I understand it, this means the java.lang.UnsupportedClassVersionError exception should not be made.

  
  

  So I am confused - is there something I can do to diagnose or fix this?

  
  

  
  

  Thanks for your help!

  It is clearly the problem of the management of versions. Re-compile all your classes with JDK 1.6 and deploy once more, if you don't know that users are running on JDK 1.7. Backward compatibility will never be a problem in the java programs have complied.

  On another note, in systems where you get this problem, go to the Java Control Panel and see the correct JRE version used by this particular user's system. Each system you have by default installed JRE and which will be used by browsers most of the time

• ORA-29552: check warning: java.lang.UnsupportedClassVersionError

  Hello
  I am trying to load a class file into Oracle using loadjava and I get the following error:
  
  ORA-29552: check warning: java.lang.UnsupportedClassVersionError: helloworld (unsupported major.minor version 51.0)
  
  Without doubt, this is related to an inconsistency between the jdk I used to compile helloworld and the Oracle JVM? Or something like that?
  
  My JAVA_HOME is C:\Program Files (x 86) \Java\jre7\bin
  My version of javac used to compile the code is javac 1.7.0_15
  Java-version is '1.7.0_15 '.
  When I do a find on java.exe in the oracle installation directory (I'm under 11.2) I get
  
  J - PC:J > find - name java.exe
  ./Product/11.2.0/dbhome_1/JDK/bin/Java.exe
  ./Product/11.2.0/dbhome_1/JDK/JRE/bin/Java.exe
  ./Product/11.2.0/dbhome_1/JRE/1.5.0/bin/Java.exe
  
  Finally, the jdbc jar is ojdbc6.jar
  
  BTW, the code is just the ordinary Tester:
  

  import oracle.jdbc.driver.*;
  
  public class helloworld {
  
      public static String hello()
      {
          return "Hello World";
      }
  
      public static String hello(String s)
      {
          return "Hello " + s ;
      }    
      
      public static void main(String[] args)
      {
          helloworld.hello();
          helloworld.hello("Larry");
      }
  }

  How can I get this class file loaded? Thank you very much
  Jason

  I suggest you load the file source instead. As cardan2 said all the class in the database files MUST be compatible with the internal JVM used by the database. For 11g versions it is Java 1.5 and the major version in the 1.5 Java class files is 49.

  You also have to take the same version in account number if you need load all the jar files in the DB. That the load will be successful if these classes have been compiled for a later version of compatibility of Java. ;

  If you load the source file and compiling the virtual machine JAVA DB will be used and you will not get this exception. You will also make sure that you use the correct support classes; for example, classes for the JDBC driver that you import will be versions of the JVM and those will NOT be the same as those of ojdbc6.jar.

  You must ensure that you are not currently using the JDBC classes or features that are not available in the version of DB of the driver.

  Using Java and JDBC in the database means that you might be able to take advantage of the internal JDBC driver for Oracle. Refer to the chapter "Server - Side internal Driver" of the Dev Guide JDBC for more details.
  http://docs.Oracle.com/CD/B28359_01/Java.111/b31224.PDF

  Overview of the Server-Side Internal Driver
  The server-side internal driver is intrinsically tied to Oracle Database and to the Java
  Virtual Machine (JVM). The driver runs as part of the same process as the database. It
  also runs within the default session, the same session in which the JVM was started.
  
  The server-side internal driver is optimized to run within the database server and
  provide direct access to SQL data and PL/SQL subprograms on the local database. The
  entire JVM operates in the same address space as the database and the SQL engine.
  Access to the SQL engine is a function call. This enhances the performance of your
  Java Database Connectivity (JDBC) applications and is much faster than running a
  remote Oracle Net call to access the SQL engine.
  
  The server-side internal driver supports the same features, application programming
  interfaces (APIs), and Oracle extensions as the client-side drivers. This makes
  application partitioning very straightforward. For example, if you have a Java
  application that is data-intensive, then you can easily move it into the database server
  for better performance, without having to modify the application-specific calls.
  

• java.lang.UnsupportedClassVersionError when loading bridges IB connectors

  Passing of one of the problems to the other... Installing PeopleTools on OEL5 8.52. Everything works; Database, application server, Task Scheduler process etc. However when I try to load the Integration broker gateways connectors I get the following error:
  
  java.lang.UnsupportedClassVersionError: Bad version in .class file number
  
  8.52 came with JRE 1.6.0 installed in the PS_HOME directory. $JAVA_HOME here and $JAVA_HOME is one of the first variables in my $LD_LIBRARY_PATH. I created a new domain after setting this correctly, because initially the JRE directory of Tuxedo preceded that of PS_HOME. I modified it in the tux.env everything seems to point to the JRE in the PS_HOME now. I always get this error however and it seems I'm missing something. Does anyone have an idea? When executing "including java' get the path correct and 'java-version' specifies the correct version. I tried several solutions posted on support of Oracle, but nothing helped. More later certified Java version is the version 1.6.0_23 - b05, but I am unable to find a download for that location. I doubt, that it is necessary to update of the JRE, since it is already running on 1.6.0.

  No, sorry, perhaps misunderstanding. I was using this jdk for Weblogic installation, as it seems that you have done.
  The symbolic link to jre under $PS_HOME goes to $PS_HOME/jre1.6.0.

  I just had some problem to be able to print a PDF file that has sent me a reliable source of the school. He could not open with precision and would not print. I was told a few undesirable and the part of it said:

  User CMN3101E the system is unavailable due to "java.lang.NullPointerException".

  I then Googled that and found the I needed to have the video drivers Intel and not the versions of MS due to some problems. I went through all this mess by using Device Manager and switched 2 pieces of diff for Intel drivers Intel and not versions of MS. I also did an UPDATE MS after a reboot to ensure that another MS Update would not reinstall certain versions of MS and if he found them I wanted to mark them for future IGNORES and ignore them now.

• ToolBarMenuButton.AddMenuItem (ApplicationMenuItem) survey java.lang.Error

  ApplicationMenuItemRepository.getInstance () .addMenuItem (ApplicationMenuItemRepository.MENUITEM_SYSTEM, applicationmenuitem)

  It shows an error: "Eception exception: Java.lang.Error.

  The exception cannot be caught and does not appear in the debugger, only on the phone.  It happens once ToolBarMenuButton.AddMenuItem calls toString in the ApplicationMenuItem, but the chain is fine - a literal.

  The call stack is several levels deep within unknown methods.

  Works fine in simulators and on the storm, but not on a 8330 4.5 running.

  Solved.  For some reason you need PIM / permission to organizers to add the entire system menu items.  I got the module defined with this permission, but the CodeModuleGroup didn't.

  They did of course difficult to debug it - he didn't throw a ControlledAccessException as it was supposed to.  Instead, he threw something that cannot yet be intercepted, which means that if users don't have the right permissions, the bombs of the app with an error that could be anything.

  Checks permissions and prompting if necessary, but in the past have always had requests for assistance relating to permissions yet, so it does not always work.

• Unrecoverable internal error: java.lang.NullPointerException when compiling

  Recently, I changed my code, and when I am compiling it, I got this error:

  Unrecoverable internal error: java.lang.NullPointerException

   

  Previously, I had met this exception several times, but when running the application in the Simulator.

  I've tried the cleaning project, cleaning the Simulator and even restart the laptop. Did not work.

  The same error persists.

  Maybe it's a bug in the compiler?

  Finally, I found the culprit:

  I put 5 large images (total size: approximately 18 MB) in the "res/img.

  The solution is to load these images from an SD card.
