Java.lang.Error: IP Helper Library GetIfTable function failed

Some of our users are sometimes getting the following exception:
java.lang.Error: IP Helper Library GetIfTable function failed
java.net.NetworkInterface.getAll(Native Method)
java.net.NetworkInterface.getNetworkInterfaces(Unknown Source)
Does anyone know why this happens and what can be done against it?
Is this a bug?

The operating system is Windows XP, Java is version 1.6.0_03 Sun Microsystems Inc.
Today, I got another error report containing this error. They all seem to come from the same user. Given that the user is still using our product, I guess it doesn't happen every time. :) The error actually happens in a third party library that uses JNI, so it could also be possible that this library messes up something. Given that the error happens rather rarely and we haven't got much data, I guess it isn't worth investigating this further at the moment.

Java.lang.Error - HELP!!

Ei guys,
I've never used JMF before. I was assigned to debug this problem. Please help.. I have absolutely no idea what caused this error. I don't know where to start.
Well, the error message is :
Exception in thread "JMF thread: TimedStartThread ( startThread: com.sun.media.ProcessEngine@ee7a14)" java.lang.Error : DataSource must be connected before it can be started
at com.sun.media.protocol.BasicPushBufferDataSource.start(BasicPushBufferDataSource.java:47)
at com.sun.media.multiplexer.RawBufferMux$RawBufferDataSource.start (RawBufferMux.java:522)
.....

I doubt that the error is caused by " java.io.* " which is not included in MIDP so that my program cannot run in WTK21.. is that true?
if yes, what can I do with it because I have to run it in WTK21 for demonstration. thx!!!!!

Export Release Build error - Exception in thread "main" java.lang.Error: Unable to find named traits

I've been developing an AIR application for Android and iOS. During development, I've run the application (in debug mode) in the desktop simulator as well as on an iPhone 4 and a Nook Tablet.
However, I recently tried to "Export Release Build" for iOS and hit the following error: (I've stripped out the package and class information in the error message below)

The class the error message is referring to is defined with a SWC that my project links to. However, I've even tried to define a class with that same name (and location) within my project and it still fails to find it.
Why am I able to Project->Clean and run this project within the desktop AIR player (or on the device in debug mode) but unable to export it as a release build?
I have found a couple of threads mentioning a similar error but none of them have been marked as resolved.

At this point I feel I am talking to myself, but I will share my work-around in case it helps another who may stumble across this post.
In my particular case, both my main AIR application and my ANE wrapper library were referencing the same external Flex library (same revision). Both projects had the library linkage set to merge. Changing the linkage to "External" on one of the 2 libraries (it doesn't seem to matter which) and leaving the other as "Merged into code" enabled the export to complete without the bizarre "Unable to find named traits" error.

I mistake this line
<arg value="-external-library-path+=${APP_ROOT}/libs/PureMVC_AS3_MultiCore_1_0_5. swc" />
must be
<arg value="-library-path+=${APP_ROOT}/libs/PureMVC_AS3_MultiCore_1_0_5.swc" />
for include the content in the swf.

Thanks Amjad. It worked for me as well!!
I think the reasoning behind this is: If we deploy it from the Application tab, it deploys the EAR file whereas simply right clicking the project and deploy, deploys the WAR file.

JRE 1.4.2_02 on solaris: java.lang.error

Hi,
I've just installed JRE 1.4.2_02 on a server running Solaris 8. The installation procedure went by without problems/errors (as described on Sun's pages: http://java.sun.com/j2se/1.4.2/jre/install-solaris.html)
When I try to execute java.exe (i.e: java -version) I get the following error response:
Error occurred during initialization of VM
java.lang.Error: Properties init: Could not determine current working
directory.
If I log in as root I'm allowed to run java.exe without problems. I'd really appreciate any ideas, views, comments etc. on what might be the problem ...
/Regards Jennifer Lee

I've posted this a couple oif other places today as well, but essentially it may help
I had the 'Error occured ..., VM' problem after installing 1.4.2_01 on Linux under slackware9.1.
I found the resolution by running 'java -verbose' as root and as a user and comparing the output, as java ran fine for root.
Turns out that for the user 'java -version' stopped after loading a couple of jars, and as root it didn't.
These jars in the JAVA_HOME/jre/lib directory only had root read/write permissions. After changing these permissions to all read and root write it worked fine for the user (so far)
The above may be of some help, but comparing the differences (especially permissions) in running it as root and user with -verbose may help.

The technique to solving Uncaught exception: java.lang.Error (and probably many like it too)

It was a blessing in disguise that the above error came about or else I wouldn't have taken the effort to find a solution. At first, I tried to delete several apps, do a hard reboot several variations but it still wouldn't go. Then I thought of downgrading the OS back to the default version so that made me give the Blackberry Desktop Manager a try. Linking handphone to notebook, it was only then I found out an updated version was available so immediately I decided to update since the jump from version 5 to 6 was worth it. After the corrupted version was wiped out being replaced by a newer one, my problem was solved!

Hi
1. Try to remove the batteries first reboot that will clear the application error
2. Also try uninstalling the last application you installed before the error appears and reboot / unplug the battery. You can reinstall these applications later.
3. If it still errors, you can wipe your handheld to clear / delete all the applications and reinstall the application required. How to delete all data and applications from the BlackBerry smartphone using the Security Wipe optio...

Hello Vilorosheramy
This error usually means you have a data corruption , then what you can do:
1. Performing a backup
2 . Remove the device
3 . Restore Data
To make a backup using the BlackBerry Desktop Manager
Connect the BlackBerry to the computer running BlackBerry Desktop Manager.
Open BlackBerry Desktop Manager.
You click on Device - make backup.
Select Complete.
Choose a location to save the backup file and then you click Backup .
Then to remove the device from the main menu go to options - security options - security wipe.
Post . - This step will erase all your data and will return to the state the BlackBerry out of box.
Once you restart your BlackBerry , use the BlackBerry Desktop Manager again to restore data.
If your problem evidences the persistence you'll have to make an OS upgrade your Blackberry.
Regards...

Uncaught exception: java.lang.Error: 137 in JavaFX

Hi
I am getting the error mentioned in subject while trying to Run a JavaFX application "Run in Mobile Emulator" mode. I am trying to use split() to separate concatenated String. The code snippet is given below :
*onMouseClicked: function(e : MouseEvent) : Void {*
println("Inside on Mouse Clicked...");
var sample = "Sherlyn|masrrev|Other";
var names = sample.split("\\|");
*println("{names.toString()}");*
The error that I get is pasted below:
*Inside on Mouse Clicked...*
*Uncaught exception: java.lang.Error: 137*
*- testsplit.Main$2.lambda(), bci=43*
*- testsplit.Main$2.invoke(), bci=2*

*- com.sun.fxme.runtime.RunnableQueue$Manager.run(), bci=86*
*- com.sun.fxme.runtime.RunnableQueue.run(), bci=38*
testsplit is the Javafx project created in Netbeans.
However the same application executes without any error when run in "Standard Execution" and "Run in Browser" mode. I am using Netbeans --> right click on the project --> Properties --> In Project Properties Window choose --> Run --> Standard Execution. or --? Run in Browser.
Is it that split() is not supported by Mobile Emulator? Please do get back to me if anybody has any answer to this.
Thanks in advance..

I don't have NetBeans, so I can't answer for sure.
I had to [read a bit|http://developers.sun.com/mobility/personal/articles/pbp_pp/] on differences between profiles, in particular [between CDC and CLDC|http://www.java-tips.org/java-me-tips/midp/what-are-cdc-and-cldc.html]. Apparently StringTokenizer belongs to CDC, which is available only to high end mobile devices. If I look at [Semsung phones' Device Specifications|http://developer.samsungmobile.com/Developer/index.jsp], most of them, for example, support only CLDC 1.1 with MIDP 2.0.
On the other hand, [MIDP 2.0|http://java.sun.com/javame/reference/apis/jsr118/] seems to have even less classes & interfaces than you show, so it is confusing.
Here is the dumbest method, doing all the work by hand. Not properly tested due to lack of time (check with separator at end, at start, consecutive, no separators...):
function SplitCLDC(string: String, separator: String): String[]
var parts: String[];
var prevPos = 0;
while (true)
    var pos = string.indexOf(separator, prevPos);
    if (pos < 0)
      var lastPart = string.substring(prevPos);
      insert lastPart into parts;
      break;
    var part = string.substring(prevPos, pos);
    prevPos = pos + 1;
    insert part into parts;
return parts;
}

The reason (as others have pointed out) is, that some paths through your method don't return a value.
I'll re-write your code in the code-style that I usually use, because then it might be easier for you to see the problem:
public boolean find(MusbachJ_Person person,BstNode node)
     if(node.intData.compareTo(person)==0) {
          return true;
     if( node.leftNode != null ) {
          find(person,node.leftNode );
     if( node.rightNode != null ) {
          find( person, node.rightNode);
     else {
          return false;
}There are two prolbems. I'll spell out the first and let the other one for you to find:
1.) you don't do anything with the return-values of the find-methods you are calling. What do you want to do with them?
2.) What do you return if the current node is not the one that you want and you've got a right node?

Java.lang.Error: Properties init during DI install

Hi,
I am trying to install a Dialog Instance and am running into an error
message java.lang.Error: Properties init: Could not determine current
working directory.
I have already uninstalled the instance and started over and I got stuck on the exact same step again.
Here is the truncated log

I have already checked the permissions and bounced the server and retried to no avail.

Any clues ?

First, when posting code in the future, use the code /code tags. Just highlight the code and click the code. button.
The error probably occurred when you tried to launch the class as an application by entering "java PostfixInterpreter" The java application launcher looks for a method in the PostfixInterpreter class whose signature is exactly public static void main(String[] args)(except 'args' can be any legal variable name). Since your PostfixInterpreter class doesn't have this method, you get the error. If you want this class to run, you have to include the method and code inside the method that runs the application.

Java.lang.error Undefined operation name CreateStore

I was trying to call a WS client using a UI application. However upon calling the client, I hit this issue.
Caused by: java.lang.Error: Undefined operation name CreateStore
at client.inventory.webservice.ReferenceUim.getReferenceHTTPPort
at client.inventory.ui.util.WSCaller.getReferencePort
at caller.ui.inventorygroup.delegate.Delegate.assignStockWS
at caller.ui.inventorygroup.delegate.Delegate.assignStock
at caller.ui.inventorygroup.bean.Results.assignStock
By the looks of it can be seen that the error was caused becaused the operation "CreateStore" not exists in my client. However:
It does exists
I did not call "CreateStore" from the UI instead I was calling "AssignStock" operation as you can see from the error trace.
Both operations are present in my WSDL.
<wsdl:operation name="AssignStock">
<wsdl:input message="invws:AssignStock"/>
<wsdl:output message="invws:AssignStock"/>
<wsdl:fault name="InventoryFault" message="invws:InventoryFault"/>
</wsdl:operation>
<wsdl:operation name="CreateStore">
<wsdl:documentation>This operation is used to create store </wsdl:documentation>
<wsdl:input message="invws:CreateStoreRequest" />
<wsdl:output message="invws:CreateStoreResponse" />
<wsdl:fault name="InventoryFault" message="invws:InventoryFault" />
</wsdl:operation>
Can help please to advise what was wrong on this case? Please let me know if I did not post enough information.

Hmm. Maybe the method is not defined in that class.

Java.lang.error How to..

I have serious problem..a lot of java games/applications show this error: java.lang.error (not found..) how can i make its work? my phone have midp 2.0..there isn't a soluction? pleeese help me

Hi Patrick
The interface is not changed and also the note no. as suggested by the Nagarajan is also not helpful. I would like to know what kind of illegal access i'm trying to do as nothing it is specifying in the Stack trace.
Following is the stack trace:
<i>
java.lang.IllegalAccessError: tried to access method com.bp.ngl.cust.bwmodel.BWModel.wdGetStaticMetadataCache()Lcom/sap/tc/webdynpro/modelimpl/dynamicrfc/DynamicRFCModel$MetadataCache; from class com.bp.ngl.cust.bwmodel.Zy_Search_Supp_Reports_Bw_Input
