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 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

  • 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 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 have been using OEM for the monitoring of the database. Recently, I've seen more error on screen

    java.lang.Exception: ORA-01017: name of user and password invalid. connection refused - wait_bottlenecks

    So I reset password with the same value to reopen. I still get this error.

    I don't know why I'm not able to login with the same password I used to change the statement.


    Thanks for the help in advance.

    Let's not your syntax.

    When you say 'identified by values' you tell Oracle 'this is not the password, but it is a salted and hashed password.

    Do not use 'values '.

    Technically,-is not a password valid, so I'll use it valid to demonstrate:

    In 12.1.0.2, it will not allow you to use '-' because this isn't a valid hash value, so I can't prove that it works, but you get the idea

    Thanks to Varun Guruvugari (Support Salesforce) who responded with below the answer on another forum:

    --===========================
    There are countless reasons for uninitialized encryption error, but I'm sure that this reason is because of SSL certificates and you saw the error above for good reasons that salesforce.com ensures the safety and security.

    You will be able to integrate successfully in this instance, by deploying the latest version of the files of Extension JCE (Java Cryptography) unlimited strength jurisdiction policy-6 for JDK1.6 on the server SOA in FMW.

  • 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.

    Hello and welcome to the community!

    There is virtually no diagnosis of those - they are the equivalent of random errors in Windows for which trace the root cause is futile. Basically, here's the last out in the programming code - some event occurred for which there is no event handler in the code. The patch is an update of the code that handles the event... but, again, what is the event is almost impossible. So, there are a few things to try:

    Sometimes, the code simply is damaged and needs to be updated - just like a reboot:

    • Each time a random strange behavior or slow creeps, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy.

    If it doesn't boot properly, then you need to try Safe Mode:

    • KB17877 How to start a BlackBerry smartphone in safe mode

    There may be a code updated to the value of the carrier - check out them through this Portal:

    The toughest possible causes are a bad application behave. To find it, there are two options. Is to see if you can read the log file:

    Go to the home screen. Hold down the "alt" key and type "lglg". (You won't see anything as you type). This will bring up the log file. Scroll down (probably a lot of pages) until you see a line that says "eception execption. Click on this line. The application name will be in the info. Alternative methods to implement the newspapers are in this KB:

    • KB05349 How to activate, view, and extract the the event logs on a BlackBerry smartphone

    The other method is to remove the apps one at a time, wait a while between the two (I usually recommend a week), until the problem stops... revealing the offending application. Yet another method is to recharge the BB OS itself, leaving little time between the addition of other applications on the BB in order to be able to determine exactly what is the cause.

    Good luck and let us know!
