• 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)

  }

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

  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 I compile my java file, there is no error. But when I run this code, it is in error:
  java.lang.UnsupportedClassVersionError: MyClass (unsupported major.minor version 50.0).
  
  What is this error? Why I get this error? How to solve this error?

  I suspect that another JRE is intalled on your computer, maybe even that some third-party software, and the path variable contains the path to the java.exe in front of your "last updated."

  Check the contents of the PATH system variable.

• 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

  I have to run ant or change the file manifests after placing the pot?

  in a site I find that we must place the pots under < DOMAIN HOME > directory / lib. Is this correct?

• Java games crashing when loading on Satellite Pro C660D

  So I have the Toshiba Satellite Pro C660D for Christmas. The first thing I did as a teenager was to examine the specifications to see if she would be able to reasonably run the games.

  Care was fine for me. So I installed a few games, Minecraft installed first, which crashed. I then install Farming Simulator to see if it was just Minecraft, farming Simulator crashed.

  I tried to install the latest drivers from the Web site intel however, Setup seems just close when the installation is about to begin.

  I am really very disappointed because my old Dell inspiron 1525 which has been literally if collapse will run these games very well.

  If anyone can help it would be much appreciated.

  Thanks in advance,
  Connor

  Chalky Hello,

  You're not alone, my son has saved his Christmas money to buy a Satellite C660-21Z. I checked on the minecraft site by putting in the specifications of the machine and it should work just fine. When we try, it crashes when connecting.

  This seems to just be a Toshiba _problem games_ java running, and there is already stuff of minecraft in this regard support forum. I started in Bartpe XP and got, it works using _it is not a hardware problem, _ but the satellite comes with win7 and I don't want to go down.

  I tried to put java day and according to the minecraft forum, the problem is that the Satellite comes with the ATI driver that needs to be removed. That would be wise because it works with a Bartpe bootable disk, but not with the Toshiba software package. I'm afraid to support Toshiba seem very reluctant to help, because you have probably already found. >>

  As minecraft works ok off a bartpe cd, I would say that there must be a problem of Toshiba running and it works ok on other laptops, and also other Java games seems to fail on the C660, I guess that there is a conflict of drivers with java. I'm sorry, but nobody else seems to be able to get a c660 longer works.

  I bought mine from Amazon that I noticed that many of those "renovated", may be returned and exchanged because they do not have Java?
  I'm giving my son until January and then request a refund if we cannot make it work.

  Sorry I can't help more and please let me know if you get a solution because otherwise it seems a nice laptop.

  Not sure where your problem is, but there are some things that I am not comfortbable with your current code.  This is a replacement code.  You can give it a try?

  The major changes are:

  (a) in the settings, we do not create a new object of Configuration, we update the existing object.  Also note that StoreConfiguration.getConfiguration (); should never return null.

  (b) in StoreConfiguration, I tidied up to account for what was happening in fact of suite and there is never a single _data object (Configuration)

  (c) in the Configuration, the hash table is more static.

  Apart from a bit of as, these changes reflect the fact that static may not be a singleton.  If you are referring to the Configuration of two different processes (a background app started at the beginning of time and a leading user interface component started with an alternative entry), you won't see the same object simply by using a static.

  Sorry, none of the code has been compiled, but I hope you understand intentions.
