Java.util.EmptyStackException

Hi All,
I am trying to configure weblogic 6.1 with Iplanet Webserver 6.0. I have all the EJB's placed in weblogic and the client class,jsp's and servlets in the IWS. I am getting theHome page but when I enter the user name and password I am getting the following error.

Kindly any one help me to solve this problem.
Thanks and Regards,

I have no idea, I would have assumed that it would accept some trash coding. Correcting that particular example might provide some progress towards an answer.
If the answer is that you have to have clean HTML, I'd look into HTMLTidy (I think JTidy is its Java implementation).

Java.util.EmptyStackException Mapping error

Hi All,
I am integrating SAP ECC 6.0 system with SAP SNC.
For these i am using standard content of SAP SNC
I am getting following mapping error :

hi,
check the interaface mapping which is used in your flow
inside integration repository - is it working over there?
do you see the XSL file in the external archives in repository?

No graphs in DB load test: java.util.EmptyStackException

Hi,
We're getting ERROR [ViewGraphAction] Error creating counter tree java.util.EmptyStackException in wls_oats when trying to "view Run Graphs".
It does not show any tree, so it is impossible to select graphs.
Anyhting we can do about this?
Edited by: ao on 2011-jun-14 16:28

may be because you r trying to re-use the border edge variable. Try having a new instance. If that doesn't work, then check for JVM settings on either boxes of WinXP and MAC.
hope i make it ;-)

Error while deploying a web service whose return type is java.util.Date

Hi
I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
public interface Ping extends Remote
* A simple method that pings the server to test the webservice.
* It sends a datetime to the server which returns the datetime.
* @param pingDateRequest A datetime sent to the server
* @returns The original datetime
public Date ping(Date pingDateRequest) throws RemoteException;
The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :
E:\Oracle\oc4j1003\j2ee\home\application-deployments\Sachin-TradingEngineWS-WS\
WebServices\com\sachin\tradeengine\ws\Ping_Tie.java:57: ping(java.util.Date) in com.sachin.tradeengine.ws.Ping cannot be applied to (java.util.Calendar) _result = ((com.sachin.tradeengine.ws.Ping) getTarget()).ping
(myPing_Type.getDate_1());

I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
This forces me to return a String data.
I would appreciate if someone can help me out.

Hi
I got the web service working with some work around. But I am not sure it this approach would be right and good.
I started altogether afresh. I did the following step :
1. Created an Interface (Ping.java) for use in web Service as follows :
public interface Ping extends Remote{
public java.util.Date ping(java.util.Date pingDateRequest)
throws RemoteException;
2. Implemented the above interface in PingImpl.java as follows :
public class PingImpl implements Ping
public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
3. Compiled the above 2 java files.
4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
Ping.Java
=========
public interface Ping extends Remote{
public java.util.Calendar ping(java.util.Calendar pingDateRequest)
throws RemoteException;
PingImpl.Java
================
public class PingImpl implements Ping
public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
6. Now I recompile both the java files.
7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
From Client to SOAP :
java.util.Date to datetime
From SOAP to Server :
datetime to java.util.Calendar
From Server to SOAP :
java.util.Calendar to datetime
From SOAP to Client :
datetime to java.util.Date (I am not able to understand this part of the conversion)
Any help or inputs would be appreciated.
Thanks

Unable to capture messages from java.util.logging

I have a class called (Caller.java) which invokes a method called foo from another java class(Util.java) using reflection API.Now this method foo logs messages using Java's logger.My requirement is to call foo for 3 times from Caller and capture/redirect the log messages into 3 log files.
But only the first log file is capturing the log messages(from logger) and other two are not ?
Plz suggest if I am doing somethin wrong here ?

Using List Class in java.awt / java.util ?

have a program that:
import java.util.*;
List list = new LinkedList();
list = new ArrayList();
... read a file and add elements to array
use a static setter
StaticGettersSetters.setArray(list);
next program:
import java.awt.*;
public static java.util.List queryArray =
StaticGettersSetters.getArray();
If I don't define queryArray with the package and class, the compiler
gives an error that the List class in java.awt is invalid for queryArray.
If I import the util package, import java.util.*; , the compiler
gives an error that the list class is ambiguous.
Question:
If you using a class that exists in multiple packages, is the above declaration of queryArray the only way to declare it ?
Just curious...
Thanks for your help,
YAM-SSM

So what you have to do is explicitly tell the compiler which one you really want by spelling out the fully-resolved class name:
import java.awt.*;
import java.sql.*;
import java.util.*;
public class ClashTest
    public static void main(String [] args)
        java.util.Date today    = new java.util.Date();
        java.util.List argsList = Arrays.asList(args);
        System.out.println(today);
        System.out.println(argsList);
}No problems here. - MOD

Hi,
Finally I was able to resolve after adding this jar file to the classfile
path of the application.
Now,I am trying to access use linkTable.add(new Item(222,"222","333",12.33)) in JSP.
where linkTable is a LinkedList.
It fails giving following error:
This is the Error Message from the Exception:

I dont understand why it is failing to add Item object to LinkedList.
can somebody help me in the forum in this regard.

Is there a Java utility class to help with data management in a desktop UI?

Is there a Java utility class to help with data management in a desktop UI?
I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
someone recommended JGoodies Bindings for Swing - will this work well and in FX?

Many thanks for the reply.
In the servlet create an Arraylist and in th efor
loop put the insances of the csqabean in this
ArrayList. Exit the for loop and then add the
ArrayList as an attribute to the session.I am making the use of Vector and did the same thing as u mentioned.I am using scriplets...
>
In the jsp retrieve the array list from the session
and in a for loop step through the ArrayList
retrieving each CourseSectionQABean and displaying.
You can do this in a scriptlet but should also check
out the jstl tags.I am able to remove this problem.Thanks again for the suggestion.

I also tried the same with no config properties, Still im getting the null for logger.
Can I know is there anything that im missing. Is there any property that must be set or do i hav set some config properties.
Thanks,
Siva

Well, basically that's part of the formatdefinition
that Properties uses. If you don't do it, then you
aren't really using Properties format and you'llhave
to do your own IO.Thanks for the reply. Is there anyother api or class
that can be used to resolve my problem.What is the problem? A character is escaped, but you will get : when you read the value. You don't have a problem as long as all reading / writing is done through that class.

Query not running in sql developer, neither connecting to database. Following error - java.util.UnknownFormatConversionException: Conversion = '0'. Please reply soon.

when i try to connect to oracle 11g rdbms, following error occurs -->
1. sql developer version - 4.0.3.16 (jdk - jdk1.7.0_51 externally installed) -- newly installed, giving following error when try to connect to oracle 11g rdbms.
2. sql developer version - 3.1.07.42 (jre1.6.0 included) -- used to run earlier.

Around a month ago, a similar question appeared on Jeff's block... look for checkText in http://www.thatjeffsmith.com/ask-a-question/
There was no resolution there, so (as the SQL Developer code in that area has not changed) I would tend to think it might have something to do with
1. Your Locale affecting the Formatter class's parsing of that pattern; or
2. A bug in the jdk version in use, probably also related to the Locale.
I recommend upgrading to the latest jdk1.7.0_xx update. If that does not solve the issue, then try changing the Locale.

Java.util.logging: write to one log file from many application (classes)

I have a menuapp to launch many applications, all running in same JVM and i want to add logging information to them, using java.util.logging.
Intention is to redirect the logginginfo to a specific file within the menuapp. Then i want all logging from all applications written in same file. Finally, if needed (but i don't think it is), i will include code to write logging to specific file per app (class). The latter is probably not neccessary because there are tools to analyse the logging-files and allow to select filters on specific classes only.
The applications are in their own packages/jars and contain following logging-code:
        // Redirect error output
        try {
            myHandler = new FileHandler("myLogging.xml",1000000,2);
        } catch (IOException e) {
          System.out.println("Could not create file. Using the console handler");
        myLogger.addHandler(myHandler);
        myLogger.info("Our first logging message");
        myLogger.severe("Something terrible happened");
        ...When i launch the menuapplication, it writes info to "myLogging.xml.0"
but when i launch an application, the app writes info to "myLogging.xml.0.1"
I already tried to leave out the creation of a new Filehandler (try/catch block in code above) but it doesn't help.
Is it possible to write loginfo to same specific file?

You should open/close it somehow at every write from different processes.
But I personally prefer different file names to your forced merging, though.

This can happen after modifying the calendar properties and not reloading the application. Try reloading or restarting the application. This could also mean the Calendar.properties file has been moved, deleted, or become corrupted. A default properties file can be found at:
"Tomcat-install-dir"\webapps\"your-web-application"\WEB-INF\classes\defaultPropFile\. Copy this file to: "Tomcat-install-dir"\webapps\"your-web-application"\WEB-INF\classes\. Stop and restart the web server. From a browser, run "hostname"/"your-web-application"/src/setupCalendar.jsp.

How can I create an instance of "java.util.prefs.WindowsPreferences"?

Hi All,
I was trying to find out a way to access the Windows Registry to add soome keys and and later add a string.
I found WindowsPreferences might be useful in the above mentioned context.
I was trying to create an instance of it, but when I import the class, it says it is invisible.
Can anyone let me know how to instantiate this class.
Note:- Under the same package "java.util.prefs" we have another class "Preferences", Iam able to import this one and use it in my code.
Thank You.
Regards,
Suman.H

It's true that Preferences uses the Registry on Windows systems, that does not mean you can use it as a Registry API. The only part of the Registry you can access are those branches that are set aside for java.util.prefs: HKLM\Software\JavaSoft\Prefs and HKCU\Software\JavaSoft\Prefs. IF you need to access other parts of the Registry, you'll need to use JNI or a separate Windows Registry library.

Bug on native code of OJVM java.util.zip.CRC32.updateBytes(CRC32.java)

I want to unzip OpenOffice 1.0 files inside the OJVM but it fails into the native method java.util.zip.CRC32.updateBytes(CRC32.java).
The first execution of the code runs OK, but the second not.
After a long wait it shutdown the connection and the oracle trace file shows an stack trace like this:

Basically it takes the content from a BLOB column of the wpg_document table, unzip it using java.util.zip package, look for the file content.xml and parse it using Oracle XML toolkit.
Using an open source utility which replace java.util.package (http://jazzlib.sourceforge.net/) it works perfect because is a pure java application.

PD: I am using Oracle 9.2.0.2 on Linux.

The cause of errors was a dying Westen Digital drive, specially the 48G partition reserved only for $ORACLE_BASE (/dev/sdb3 mounted on /opt/oracle).
A simple quick scan of unmounted partition (badblocks -v /dev/sdb3) reported more than thousand new bad blocks (compared to the last scan six months ago). Although I strongly believe, specially in the case of WDC drives, that the best utility to "repair" bad blocks is the one that opens a window and prints the message: "Go to the nearest shop and buy a new drive", I was very curious to prove my suspicion just on this drive. After zero-filling the partition with dd, then formatting it (mke2fs -cc) and mounting again, the 11g installation and database creation (on the same partition) successfully completed, performing fast and smoothly. To make sure it was not a casual event, I repeated the installation once again with full success. The database itself is working fine (by now). Well, the whole procedure took me more than four hours, but I'm pretty satisfied. I learned once again - stay away from Western Digital. As Oracle cannot rely on dying drive, my friend is going tomorrow to spend a 150+ euro on two 250G Seagate Barracudas and replace both WDC drives, even though the first drive seems to be healthy.
In general there is no difference between loading correct data from good disk into bad memory and loading the incorrect data from dying disk into good memory. In both cases the pattern is damaged. For everyone who runs into the problem similar to this, and the cause cannot be easily determined, the rule of thumb must be:
1. test memory and, if it shows any error, check sockets and test memory modules individually
2. check disks for bad blocks regardless of the result of memory testing
Therefore I consider your answer being generally correct.
