Get java.lang.IllegalAccessError after upgrading to Weblogic 10.3.2

Hello
We have two applications deployed on Weblogic 9. It has been decided to spend 10.3 and I installed 10.3.2.0 on Solaris 9 on a Unix machine.

The first application that is an enterprise application, installed fine and works as expected. But the second, more simple JSP / Servlet Web application is having issues. While this web application deployed properly on the new server, it throws the below exception during execution.

java.lang.IllegalAccessError: oracle/jdbc/pilot/OracleCallableStatement

It is launched on the threshold:
stmt = (OracleCallableStatement) con.prepareCall (query);

This is an existing application and it uses OracleCallableStatement, OracleResultSet etc. everywhere. As I have always used JAVA packages as CallableStatement, ResultSet etc, my first instinct was to try as follows and the exception disappeared from this line.

stmt = (CallableStatement) con.prepareCall (query);

Then, I got the exception 'exception closed statement' at the line where get me the following result set:
While (RS. Next

That's when I wondered if there is a dependency of the environment when Weblogic 10.3.2 is introduced. On Google, I found some related links but without solutions.

I also replaced the classes12.zip with the ojdbc6.zip file but without success. The JRE running on the Unix machine is 1.5.0_24 - b02. I read somewhere that JRE must be 1.6. But before you try anything else, I wanted to check if I'm going in the right direction or not.

So please let me know if you have suggestions or questions to troublshoot the question.

Kind regards
Rambeau

The classes of "driver" should never have mentioned directly, because they are internal classes
who can change, rather than the public Interfaces of oracle.jdbc. The problem you had
because while improving WebLogic, you also have a new JDBC Oracle driver with chip
in inner classes.

    The MAXL script works fine from the command line in the shell to essmsh. Environment variables have been set up correctly for essmsh. Essmsh shell called command line.


    To apply the patch, I just copied the contents of the oracledi file present in the patch on the top application of oracledi existing ODI record. Let me know if I missed a step.

    Indications will be useful.


    Thanks in advance!

    This means that you have not imported into the new KM for "IKM SQL for Hyperion Essbase (data)", you always use the original and it will fail because the new version has additional options.
    Right click the KM existing - import/replace, then navigate to SQL IKM for Essbase data.

    See you soon

    Well, if you use transient attributes that must survive passivation / activation you must ensure for the passivate. Check JDev: always Test Your App with the regrouping of ApplicationModule turns off | JDev & amp; Goodies ADF

    It't not a best practice just passivation everything without thinking. However, he must passivate some info so that your application works.

  • JWSC ant task get java.lang.NoSuchMethodError

    Hi all
    I am trying to build a webservice with task ant JWSC JDK 1.6, which uses annotations TJS and a few specific annotations of weblogic.
    I get the following error while building.
    However, when I build my IDE (eclipse) it works fine.
    I tried to copy the libraries of eclipse and ran the build. But it did not work.

    Thank you
    Sriram

    Sriram salvation,

    Before you run the Ant task you execute the following startup script?
    setWLSEnv.sh

    I found one of the customer knowledge base oracle facing the similar question like you and the issue is resolved after you run the setWLSEnv startup script.

    If the issue is still unresolved after trying the above suggestion, please attach the build.xml to this thread to see the same thing.

    Thank you

  • Trying to update vCAC Blueprint entity, gets "java.lang.NullPointerException".

    Hello

    I am trying to create a fairly complex workflow in vRealize Orchestrator.

    The purpose of this workflow is to clone a vRealize current/previous deployment MultiMachine Automation and mark the new clones as models and then update a plan Director multi-machine 'Ad hoc' vRA with these models new vCenter.

    Right now, I figured out how to map prints blueprint only computer individual Ad hoc, to clone new models of vCenter.

    This is done in the "VirtualMachineTemplateProperties" of each single computer model part.

    Thanks to a code borrowed Christiaan Roeleveld createiaasblueprintfortemplate package

    But because the components of the original deployment MultiMachine could were converted to the CPU and memory, I need to update the entity for SingleMachine component plans.

    I have one tries to use the workflow by default to "Update an entity of the vCAC model" for this.

    The code below is just hard code examples.

    I create a set of properties:

    theBlueprintEntityProperties =
{
  CPUCount : "2",
  MemoryGB : "4096",
  DiskSize0GB : "20"
};

    I then try to run the workflow 'Update an entity of the vCAC model' (inside my workflow of wrapper of cause), with the following entries:

    entity = theBlueprintEntity
inputProperties = theBlueprintEntityProperties
links = null
headers = null

    But I get just "java.lang.NullPointerException".

    Correctly, this means that I need to include links or headers.

    I tried with a few links, again using package Christiaan Roeleveld createiaasblueprintfortemplate code

    But even if I include the following links:

    var links = {
  "InterfaceType": [ interfaceType ] // The vCAC Entity for the vSphere interface,
  "HostReservationPolicy": [ reservationPolicy ] // The vCAC Entity for my Reservation Policy,
  "ProvisioningGroup": [ provisioningGroup ] // The vCAC Entity for my Procisioning Group / Business Group,
  "WorkflowInfo": [ cloneWorkflow ] // The vCAC Entity for the Clone Workflow,
  "GlobalProfiles": buildProfiles // Array of build profiles, in this case just a array of one build profile,
}

    I still just takes "java.lang.NullPointerException".

    Someone has a few entries on how to upgrade the vCAC entity for a master plan, with regard to the CPU, memory or disk?

    Environmental information:

    vRealize Orchestrator = 6.0.3 Build 3000581

    vCAC/vRA Pluging in vRO = 6.2.2

    vRealize Automation = 6.2.2 Build 2754020

    I found the problem.

    The problem is that the properties in the vRO inventory, for example 'VirtualMachineTemplateDescription' has an envelope has changed compared to the vRA SQL database.

    In the vRO inventory, it is listed as virtualMachineTemplateDescription ("v" in lowercase)

    But in the vRA, database SQL, it is listed as VirtualMachineTemplateDescription (capital ' V')

    And when properties are not what is in the database, the answer back is:

    java.lang.NullPointerException

    Here's the corrected code that updates the VirtualMachineTemplateDescription, the CPUCount and the MemoryMB of an entity of Blueprint.

    var entity = theBlueprint.getEntity();

var properties =
{
  VirtualMachineTemplateDescription : "Testing Description",
  CPUCount : 8,
  MemoryMB : 18432
};

var hostId = entity.hostId;
var modelName = entity.modelName;
var setName = entity.entitySetName;
var keyString = entity.keyString;

vCACEntityManager.updateModelEntityBySerializedKey(hostId, modelName, setName, keyString, properties, null, null);

  • Smartphones from blackBerry 8350i eception exception java.lang.NullPointerException after hard reset

    basic information:

    8350i

    v4.6.1.204 (Platform 3.0.0.73)

    Desktop Manager 4.7

    everything is good except that I was using two batteries, one in the phone and the other in a charger. When the battery is almost empty I swap with one charge naturally causing a hard reset.

    This procedure worked well for at least a week or two, until last month when I swapped batteries - after the hard reset, I had

    Eception exception: java.lang.NullPointerException

    I could make calls, but all other software were corrupted... practically nothing else worked... missing icons etc.

    tried all kinds of solutions, but the only thing that fixed it was a full-on device software erase/recharging, then a restore of data since the previous backup. at the time, I thought it was just something random and was happy to learn how to do a full charge of the software.

    then yesterday it happened again (even once, at the end of the security check immediately after the hard reset). now I'm afraid to swap batteries because it seems that every time I have hard reset it recharge a 10% chance (I guess) of corruption of software and a complete takes considerable time.

    If anyone else has noticed this? does anyone have a solution?

    can I change batteries without a hard reset; i.e. Exchange while that connected to the power supply? I have not tried this yet for fear of harming my BB.

    any help is appreciated,

    John d.

    15 seconds is too short period of time.

    It took at least a minute before returning the battery.

    Error you reported is related to badly written in device memory operating data.

    In most cases, helps to battery pull. But you must wait at least one minute before you put the battery on the device.

    When you do battery pull make sure that this device is not connected to any external device or the wall charger.

    In the event of battery pull does not help, I recommend to consider wiping the device memory.

  • Only get a gray screen after upgrade of El Capitan. What can I do?

    I tried to install an upgrade, but only now have a gray screen.  The installation seems to have stopped half way through.

    Please take each of these steps that you have not already tried it. Some of them are not applicable to your model or your situation. Stop when the problem is resolved.

    To restart a computer is not responding, press and hold the power button for a few seconds until the unit turns off, then release, wait a few seconds and press again briefly.

    Step 1

    The first step to respond to a startup failure is to secure data. If you want to keep the contents of the boot drive and you have not already at least a current backup, you should try to back up now, before we do anything else. It may or may not be possible. If you don't care the data changed since the last backup, you can skip this step.

    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to store backup data.

    a. starting the partition recovery or an hour Local Machine backup volume (button option key at startup). When the OS X Utilities appears, launch disk utility and follow the instructions in this article to support. You'll be 'restoration' the boot on the backup volume volume.

    (b) If step 1 fails due to disk errors, and no other Mac is available, then you may be able to save some of your files by copying them in the Finder. If you already have an external hard drive with OS X installed, the start of it. Otherwise, if you have access to the Internet, follow the instructions on this page to prepare the external hard drive and install OS X on it. You will use the installation program of recovery, rather than download it from the App Store.

    c. If you have access to a Mac, and it work and have both the non-working Mac FireWire ports or stroke, start the Mac non-working in target disk mode. Work Mac to copy the data to another drive. This technique will not work with USB, Ethernet, Wi - Fi or Bluetooth.

    d. If the internal drive of the non-working Mac is replaceable by the user, remove it and climb into a docking station that is pregnant or an external drive. Use another Mac to copy the data.

    Step 2

    If you have booted from an external drive, make sure that the internal boot volume is selected in the pane of the system preferences Startup disk.

    Start in safe mode. Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. If you do not see the words "Safe Boot" in the start screen, you did not start in safe mode. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, and some things don't work at all, including the networks without wire on some Macs.

    The login screen is displayed even if you normally connect automatically. You must know the password for the connection to connect. If you have forgotten the password, you will have to reset it before you begin.

    If the startup progress bar gets stuck for more than a few minutes, or the system stops automatically when the progress bar appears, the boot volume is corrupted and the player is probably defective. In this case, go to step 9. If you have another problem with the player, replace it immediately.

    If you can start and log in in safe mode, empty the trash and then open the window of info on the boot volume ("Macintosh HD", unless you have given it a different name.) Make sure you have at least 9 GB of space available, as shown in the window. If you do not, copy as many files as necessary on another volume (not another folder on the same volume) and delete the originals. Deletion is not complete until you empty the trash again. This, until the space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)

    If the boot process hangs again, the problem is probably caused by third-party software you have installed. Ask for additional instructions.

    Step 3

    If the startup process stops at a gray screen together with a mobile cursor, then the logon dialog box may be active but not visible because of a bug. You may be able to connect by using the arrow keys or the cursor to select the password field and type your password as usual.

    Step 4

    Case of failure of step 3, the boot volume can be complete. If you saw previously implemented guard space drive is low, it is certainly the case. You might be able to start in safe mode , even if you cannot boot normally. Otherwise, boot from an external hard drive, or well technology for step 1b, 1 c or 1 d allows to mount the internal drive and delete some files. According to the documentation from Apple, you need at least 9 GB of free space on the boot (as shown in the Infolog) for normal operation volume.

    Step 5

    If a Mac desktop (without the built-in keyboard) crashes on a gray screen together with a mobile cursor, the keyboard may not be recognized. Hold down the button on the side of a wireless Apple keyboard to make it discoverable. If need be, replace or recharge the batteries. If you use a USB keyboard connected to a hub, connect it to a built-in port.

    Step 6

    Sometimes, a startup failure can be solved by resetting the NVRAM.

    Step 7

    If there is an integrated optical drive, a disk may be stuck in there. Follow these instructions to remove it.

    Step 8

    Press and hold the power button until the unit turns off. Disconnect all devices wired except those needed to start and remove all aftermarket expansion cards. Use another keyboard and/or mouse, if these devices are wired. If you can start now, one of the devices that you disconnected, or a combination of both, the origin of the problem. Discover that it is a process of elimination.

    Step 9

    Launch the utility disk in recovery mode (see step 1). Select the boot volume, and then run the repair disk. If problems are found, repeat until that clear. If disk utility reports that the volume is not repairable, the drive is defective and must be replaced. You can choose to tolerate such malfunction in the reader's life. In this case, delete the volume and restore it from a backup. If the same thing happens again, replace the drive immediately.

    It is one of the rare situations where you must also run repair permissions, ignoring the erroneous warnings, that it can produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.

    Step 10

    If the boot device is an aftermarket SSD, it may have an update and/or a forced "garbage collection". Instructions how to do this with a Crucial SSD of brand have been posted here. Some of these instructions may apply to other brands of SSDS, but you should check with the technical support of the provider.

    Step 11

    Reinstall the OS. If the Mac has upgraded an earlier version of Mac OS X, you need the Apple ID and password used to upgrade.

    Step 12

    Do as in step 11, but this time clear the disk utility boot volume before installing. The system should automatically restart in The Migration Wizard. Follow the prompts to transfer data from one Time Machine or another backup.

    Step 13

    This step applies only to models that have a battery logic-board ("PRAM"): all of the Mac Pro, MacBook with a removable main battery and a few others (models not updated). A flat battery logic-board may cause a boot failure. In general the failure will be preceded by the loss of the system and boot disk clock settings. Refer to the user manual for replacement instructions. You may need to take the machine to a provider of services to have to replace the battery.

    Step 14

    If you get this far, you probably deal a hardware failure. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.
