BottomUp WebService Error: java.lang.InstantiationException
Hello,
I created a BottomUp Webservice from a java class, that calculates the difference out of two given int values. When I deploy the WebService and the client to the WAS 7.1 it's not working, I get the error shown below. I changed the Java settings of the Project to JDK Compliance 1.4, rebuild the project, recreated the .ear and deployed it to a WAS 7.0 system, it's working fine!
My next step was, to remove the project out of NWDS and to create a TopDown Webservice out of the WSDL I downloaded from the BottomUp WebService (the one which is not working) I deployed to WAS 7.1 I modified the Java code, rebuild the project and redeployed it to WAS 7.1 and it's working now.
Has any one a idea why a BottomUp WebService is not working in WAS 7.1? The only difference I see between a BottomUp and TopDown Webservice is, that during the creation of the TopDown WebService some additional Stubs, Skeleteon and Interface files are being created, but nevertheless the BottomUp WebService works fine in WAS 7.0
Thanks Holger

Hello,
the source is quite simple:
package holger;
public class CalculateDifference implements java.io.Serializable{
public int theDifferenceIs (int a, int b) {
return a-b;
How can I attach the .ear file? I don't see this possibility here.
Best regards
Holger

UI Shell: java.lang.InstantiationException TabContext$TabSelectionActionLis
JDeveloper 11.1.1.2
EJB dataContols
We have minor modification to the UI Shell but basically the the TabSelectionActionListener inner class, the tabSelectionListener private final attribute, and the refreshTabContent() method are still the same. Our application is working well except that we are encountering the above subject error once we launch a specific taskflow. This taskflow has two views (each views contains adf read-only tables drag and drop from an EJB DataControl) and with the following navigation rules:
currency_list ---drilldown--> conversion_rate_by_currency_list
currency_list <--back-------- conversion_rate_by_currency_list
<control-flow-rule id="__18">
<from-activity-id id="__19">currency_list</from-activity-id>
<control-flow-case id="__21">
<from-outcome id="__22">drilldown</from-outcome>
<to-activity-id id="__20">conversion_rate_by_currency_list</to-activity-id>
</control-flow-case>
</control-flow-rule>
<control-flow-rule id="__23">
<from-activity-id id="__24">conversion_rate_by_currency_list</from-activity-id>
<control-flow-case id="__26">
<from-outcome id="__27">back</from-outcome>
<to-activity-id id="__25">currency_list</to-activity-id>
</control-flow-case>
</control-flow-rule>If we will not invoke "drilldown" navigation in this taskflow, then we will not encounter the above error. We can open as many tabs and transfer from one to the other. But if we invoke "drilldown" in this task flow, we can transfer to another tab for once and after that, if we click another tab, we encounter the following error:

pinoThe fix is available internally and undergoing tests. The plan now is to release via the JDev "Check for Updates" option under the Help menu. This should be more convenient with broader availability. It will also mean that it has undergone formal QA testing. This will take a bit longer but in the end, but a better quality outcome. I have also replied to Oracle UI Shell Functional Pattern.

Error in file-webservice- file (Error: java.lang.NullPointerException)
Hi everybody,
I have configured a file-webservice-file without BPM scenario...as explained by Bhavesh in the following thread:
File - RFC - File without a BPM - Possible from SP 19.
I have used a soap adapter (for webservice) instead of rfc .My input file sends the date as request message and gets the sales order details from the webservice and then creates a file at my sender side.
1 communication channel for sender file
1 for receiver soap
1 for receiver file
Error: java.lang.NullPointerException
What could be the reason for this error
thanks a lot

Factory is a class which extends JApplet. Here is the init() method:
public void init(){
this.setSize(800, 600);
this.setContentPane(getJContentPane());
try{
Factory factory = new Factory("input.txt");
factory.generateClass();
catch(IOException e){}
}Any help would be greatly appreciated.Roosh wrote:
That is correct. Should I have a constructor which contains no arguments in
order for this to work correctly?Yes. The browser plugin, for example, gets the name of your applet subclass from the HTML:
<applet code="AppletWorld.class" width="200" height="200">
</applet> It instantiates your class in a way that requires it to have a constructor that takes no arguments. You didn't define this.
I also mean that Factory is a class which inherits JApplet, so the Factory is an applet.Am I correct in thinking that Factory's init method creates another instance of Factory? That's the part the doesn't make sense to me. -
Java.lang.InstantiationException / XMLEncoder error what's that?
Hello there!
After I received so much help from Joachim yesterday, I think I have to bother you again with a problem:
I wrote this application for testing purposes. This app only counts an interger up and down from 0 to 10 and displays the value in a JTextBox as Strings like int = 3 means: "three". These Strings are all in an array. Additionally, I have implemented a localisation (german and english language). I read these properties from a .properties File and change the label of the buttons and the language of the value-strings. Also I serialize my app using the Beans-persistence.
So far so good but I get an error in the following situation:
When I change the language using a JMenuBar-entry and then close the app-window (now the app status is written to a xml-file (persistence)) I get:
java.lang.InstantiationException: javax.swing.PopupFactory$HeavyWeightPopup$1
Continuing ...
java.lang.Exception: XMLEncoder: discarding statement XMLTest.addWindowListener(PopupFactory$HeavyWeightPopup$1);
Continuing ...The status is saved to the file and the reconstruction from the file works fine. But this error annoys me and I have to get rid of it. More information: when I run the app and foolin' around with the buttons BUT DON'T CHANGE the language, the error doesn't appear.
The app is working fine, but what does this error mean? I'm pretty new to Java and google doesn't help me...
Here is my code: http://pastebin.com/m6b58751c
Thanks for having a look...

The error occurred because the XMLEncoder couldn't instantiate another XMLTest object. That would be because it didn't have a no-args constructor, which it must have to qualify as a Java Bean, which it must do to be XMLEncodable (or else have a PersistenceDelegate that can instantiate it). When you changed it to have-a JFrame instead of be-a JFrame you probably changed the constructor too.Okay BUT: I have a PersistenceDelegate because I have a args-constructor:
public class XMLTestPersistenceDelegate extends DefaultPersistenceDelegate{
@Override
protected Expression instantiate(Object oldInstance,Encoder out){ // fure den übergabewert am kontruktor
XMLTest t=(XMLTest)oldInstance;
return new Expression(oldInstance,XMLTest.class,"new",new Object[]{t.width});
@Override
protected void initialize(Class<?> type, Object oldInstance, Object newInstance, Encoder out){
super.initialize(type, oldInstance, newInstance, out);
XMLTest t=(XMLTest)oldInstance;
out.writeStatement(new Statement(
oldInstance,"endisFunction", new Object[]{}));
for(int i=0;i<t.value;i++) // so oft plusFunction aufrufen, wie value groß ist
out.writeStatement(new Statement(
oldInstance,"plusFunction",new Object[]{}));
if(!t.enabled)
out.writeStatement(new Statement(
oldInstance,"endisFunction", new Object[]{}));
}The width value is the int-value of the width of my JTextField. The Statements are for some other properties of my object.
Right now, I still don't understand why it doesn't work when my Class XMLTest ist extended from JFrame.
And when I changed it to have-a JFrame I only changed some properties in my constructor of the JFrame i.e.: this.setVisible(true) to f.setVisible(true)... but nothing more.

Java.lang.InstantiationException when using Action class with constructor
Hi everyone,
I'm using the insertNewNode() method from this class in another action class, which works fine. But when this action itself is called, I get an infinite java.lang.InstantiationException (until the stack is overflowed). I'm initiating the fields required in every method in a constructor. If there is no constructor, this action works fine again. What's wrong?

.......You're welcome.
Still, I would report this as a bug at the Struts mailinglist/issuetracker. This silly behaviour shouldn't happen. Once an InstantiationException, okay, but in an infinite loop?!? That's definately a bug. Also the detail message may be more informative, e.g. "No default constructor found" or so. -
Error: java.lang.NullPointerException in BI Broadcasting
I am having this issue when I am trying Email broadcasting form SAP BI Query and set the filter navigation for one of the characteristic value. Any Idea???
When I execute the Information broadcasting it gives following message
Error: java.lang.NullPointerException
Thanks,
AddyHi Janine,
The query works in Java Web and in BEx Excel analyzer. This query even works in the BI email broadcasting for different filter value for the same characteristic in the filter navigation tab setting in broadcasting.
The same filter value works in Broadcasting when I am broadcasting the query as Excel attachment but does not work when I try to do a PDF report.
The popup error message is this:
Execution of Broadcast Setting
Setting Z_ORD_PTYP_SM_INT_YN_WK were started from the BEx Broadcaster

using the getString() method works fine but getTestBean() doesn�t;
any clue on this?
thanksHi,
I'm experiencing exactly the same problem as you ...
The only fix I found is to use static invocation ... with static invocation, WSCompile generates a deserializer and everything works fine, no mure NullPointer exception ...
With dynamic invocation as you are trying to manage here, I didn't find any way to tell the client to use the deserializer generated with wscompile ...
Does anyone know how to do it ?
Thanks,

Can someone throw some light based on this error, I know its hard to know but any clue is highly appreciated.
Thanks a lot !Hi experts,

Exception: java.lang.InstantiationException.....
Hi there,
I have recently been playing around with converting an application to an applet. Everything seems great at my end, I have tried ir in 'Internet Explorer 6' & 'Netscape 6.2', they both show the applet, however 'Opera 5' does not. The annoying problem is that nobody else can see the applet in thier browser's. Because I can't experience what they are seeing it is proving really dificult to troubleshoot this error. The only indication I have to the route of this problem is the message:
Exception: java.lang.InstantiationException.....
I have even remove this class file from my own P.C. just to make sure that some how I am not viewing the local class on my computer instead of what I have uploaded. It had no effect on my results as I suspected. Could it be I need to use a H.T.M.L. convertor?
I am a bit stumped. Does anyone know what trhis error message generally means.
If you want the code I can e-mail, but in the mean time if anyone is familiar with this problem, HELP!!!the previous post pretty much explained what the Exception means exactly. To be more specific however, your compiler would not let you instantiate an interface or abstract class so either a) you are doing this incorrectly via reflection or b) there is some class conflict with client system. Is your applet enclosed in an applet tag that directs the browser to use the sun plugin? I would recomend that you have clients use the sun plugin- it will probably solve this problem (assumming it is not bad code) and you should run into less conflicts between different browser types.

Dear Friends,
I am developing javabean connectivty for inserting records to mysql database from jsp. when i try to compile java bean program. It gives an error like unreported Exception java.lang.InstantiationException: Must be caught or declared to be thrown*. This is my mode.

What could be the problem?
Thanks in advance,
RonyHi Rony,
Yes it is mandatory. The default POF serializer just calls newInstance() on the Class to create an instance and it has no way of knowing how to call parameterised constructors. If you must have parameterised constructors then you would need to use external serializers rather than implement PortableObject. The docs are here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/api_pof.htm#BABEJCFF
Does your Dev environment only have a single Coherence process, if so then nothing will be getting serialised so you will not see this sort of error. This is a common dev mistake and if possible you should always write Dev tests to use multiple nodes and also write unit tests to test POF serialisation.
Writing a unit test is pretty easy...
ConfigurablePofContext ctx = new ConfigurablePofContext("... name of your pof config file ...");
CacheRowDataExtractor value = new CacheRowDataExtractor......
Binary binary = ExternalizableHelper.toBinary(value, ctx);
