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 BalusC,
Thanks for your suggestion. I used try catch block also. But it still gives same error. I have modified my following code. Is there any thing wrong in my code? Please give me your suggestion. Thankyou.

class looks like:-
public class CacheRowDataExtractor extends AbstractExtractor implements
PortableObject, Serializable {
// code
What could be the problem?
Thanks in advance,
Rony

Hi 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);
CacheRowDataExtractor result = (CacheRowDataExtractor) ExternalizableHelper.fromBinary(binary, ctx);
... now assert result is equal to original value ...JK

thank you for your time

I can't see anywhere in your code that tries to create an Activator object... i.e. there is nowhere that tries to use the new Activator() constructor, so I would suggest that the problem is not with your code.
This is the description of Instantiation Exception from the API:
Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated because it is an interface or is an abstract class.
So, I would imagine, somewhere the Class.newInstance() method is being invoked on Plugin (the abstract class) rather than Activator (the non-abstract one)

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.

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>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:

The 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.

I'm using a User defined function "getFGN" to call a Java Class developed in NWDS. the source in NWDS has no errors when it is build. But when i Run the code i get error below.
Buy using the Debugging facility in NWDS i can see that the problem is this code linie:

Hi,
Looks like your CLASSPATH is not set properly...Just try to Put the Jar inside "<DOMAIN_HOME>\lib" directory...in that case u need not to alter anything in the Classpath variable...it will be appended at the end of Classpath at the run time, Using Extended Directory ClassLoader.
by default Classpath settings doesnt take effect if we specify it in the startScript of Servers but we start them using NodeManagers...So if you are using Nodemanagers to start your Servers... then you can follow the below link to set the Classpath & Memory Arguments http://weblogic-wonders.com/weblogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/

I am using JDK 1.5 and Apache/1.3.19
Can anyone help me out ....?

for URL'S Starting with HTTPS only.....Sometimes it works and sometimes it gives me the classcast exception
As soon as I bounces my Apache application server...then it starts working...I dont know why its happening like that..
Is there any issue with the Ports I am trying to connect or some Apache configuration files settings are getting changed ?

Uncaught exception java.lang.ArrayIndexOutOfBoundsException in J2ME

hi all,
i found a strange error (uncaught exception java.lang.ArrayIndexOutOfBoundsException) every time when i tried to developed a MIDlet and servlet to retrieve data from database. can anyone tell me why this error occur? this is example of MIDlet code:
public void checkResult() {
HttpConnection conn = null;
InputStream is = null;
OutputStream os = null;
byte[] receivedData = null;
String userid = "123";
try {
String url = getAppProperty("Result.URL");
conn = (HttpConnection)Connector.open(url);
     byte postData [] = ("userid=" + userid).getBytes();
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
     conn.setRequestProperty ( "Content-Length", Integer.toString (postData.length));
conn.setRequestProperty("Connection", "close" );
conn.setRequestProperty("Content-length",Integer.toString(postData.length));
     os = conn.openOutputStream();
     os.write(postData);
     os.close();
     is = conn.openInputStream();
     String contentType = conn.getType();
int len = (int)conn.getLength();
if (len > 0)
receivedData = new byte[len];
int nb = is.read(receivedData);
else
receivedData = new byte[1024];
int ch;
len = 0;
while ((ch = is.read()) != -1)
receivedData[len++] = (byte)ch;
response.setText(new String(receivedData,0,len));
display.setCurrent(outputForm);
catch (IOException e) {
System.out.println(e.getMessage());
e.printStackTrace();
finally {
try {
if (is != null) {
is.close();
if (os != null) {
os.close();
if (conn != null) {
conn.close();
catch (IOException e) {
from alice

That would be a point where I miss bounds checking on your part:
receivedData = new byte[1024];
int ch;
len = 0;
while ((ch = is.read()) != -1)
receivedData[len++] = (byte)ch; // what happens if more than 1024 characters come along??
}Otherwise the exact line of error, the stack trace or some context would be helpful.

Dynamic Configuration Error: Exception:[java.lang.IllegalArgumentException

Hi All,
I am using dynamic configuration to put a string to the message header. i have created a tilde delimited string with the length more than 200(length=928). During mapping i am using dynamic configuration to put this in SOAP header. But everytime i execute scenario i get an error:
"com.sap.aii.mappingtool.tf7.MessageMappingException: Runtime exception when processing target-field mapping; root message: Exception:[java.lang.IllegalArgumentException: Value is too long (928/200): "
Is there a limit to the length of the string that can be placed in the dynamic configuration ?
Please help.
Regards,
Meenakshi Pradhan

I think the above error does say about that..!! Try putting data like 201 chars and the 200 chars, then see what happens.

Exception:[java.lang.IllegalArgumentException: Cannot cast 02 to boolean]

Hi Friends,
I am facing a issue in mapping. My scenario is IDOC to JDBC.
I have done mapping in the give below way.
If segment1 and segment2 both exists and attyp(field of segment1) is equal to '00' or '01' then segment1 replicate into table.
I am facing a error while testing the mapping is:
RuntimeException in Message-Mapping transformation: Exception:[java.lang.IllegalArgumentException: Cannot cast 02 to boolean] in class com.sap.aii.mappingtool.flib3.Bool method or[02, 01, com.sap.aii.mappingtool.tf3.rt.Context@459926e5]
Kindly suggest me on this.

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?
public class GliederungNewAction implements Action {
     private final String DEFAULT_DESCRIPTION = "Neuer Punkt";
     private OracleConnection connection;
     private String username;
     private String catalogue;

     private String parent_attr;
     private int parent_sequenceNr;
     private int requiredSequenceNumber;
     public GliederungNewAction(OracleConnection connection, String username, String catalogue) {
          this.connection = connection;
          this.username = username;
          this.catalogue = catalogue;
     public String perform(ActionMapping mapping, HttpServletRequest request,
               HttpServletResponse response) {
          HttpSession session = request.getSession();
          // fetch the necessary parameters from the JSP site
          // the parent attribute is the selected attribute!

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.

8350i uncaught exception java.lang.NullPointerException after hard reset

basic info:
8350i
v4.6.1.204 (Platform 3.0.0.73)
Desktop Manager 4.7
everything is good except that i've been using two batteries, one in the phone and one in a charger. when the phone's battery is almost drained i swap it with the charged one which of course causes a hard reset.
this procedure was working well for at least a week or two until last month when i swapped batteries - after the hard reset i got
uncaught exception: java.lang.NullPointerException
i could make calls but all other software seemed corrupted... virtually nothing else worked... icons missing etc.
tried all sorts of solutions but the only thing that fixed it was a full on device software erase/reload, then a data restore from previous backup. at the time i figured it was just a random thing and was glad to learn how to do a complete software reload.
then yesterday it happened again (again, immediately at the end of the security check after hard reset). now i'm afraid to swap batteries because it would appear that every time i hard reset there is a 10% (my guess) chance of software corruption and a complete reload takes a significant amount of time.
has anybody else noticed this? does anybody have a solution?
can i swap batteries without a hard reset; i.e. swap while plugged into power? i haven't tried this yet for fear of causing my BB harm.
any help is appreciated,
john d.

Hello, John.
Make selective backup as it is described here:
http://supportforums.blackberry.com/rim/board/message?board.id=8100&view=by_date_ascending&message.i...
Backup only information that you need.
There is described the purpose of every database you can observe when you're doing the selective backup:
http://www.blackberry.com/btsc/KB03974
When you have done selective backup do the following.
On your device go to: Options - Security Options - General Settings
Open menu and select "Wipe handheld"
