Javax.imageio.ImageIO: LUT has improper length!

I have a problem similar to those described in these forum postings:
http://forum.java.sun.com/thread.jspa?forumID=31&threadID=404731
and
http://forum.java.sun.com/thread.jspa?forumID=256&threadID=510170
I use the following code:
String imageURL = "http://a-valid-url";
java.net.URL url = new java.net.URL(imageURL);
javax.imageio.stream.ImageInputStream iis =
javax.imageio.ImageIO.createImageInputStream(url.openStream());
java.awt.Image img = javax.imageio.ImageIO.read(iis);
The server at the end of the URL sends back an image in PNG format. The code works fine except on the rare occasions that the image is only black and white, when our old friend the java.lang.IllegalArgumentException is thrown with the message "LUT has improper length!". (I think the exclamation mark on the end is a nice touch.)
I understand from the other postings that this is a shortcoming in the class I am using. Does anyone know of a way to work around it?
Thanks in advance!

Can't find default package `javax.imageio' error

We are running jdk "1.4.2_05-b04" on linux. And I have a simple program that is importing package javax.imageio. But the compiler is not finding it. Now since this is a j2ee envrionment I am using ANT to compile. Here is the error I am getting:
--- BEGIN ERROR TEXT---- [javac] /home/sroshan/samcvs/psimc/src/com/psi/psimc/tasks/servlets/StockGraphProducer.java:28:
error: Can't find default package `javax.imageio'.
Check the CLASSPATH environment variable and the access to the archives
[javac] 1 error
--- END ERROR TEXT----
Here are my questions:
1-Any one has any idea why this package may be in a special location in my jdk path that ANT can not find?
2- What jar file would be containing the javax.imageio package?
Since at list I could see if that jar may be included into my ANT classpath or not.
Any help is appreciated
Regards
Siamak

Hi,
hey..I am also getting the same error. Please let me know what do you mean by path was so long??
Are you talking about system Path variable or the installation path?I believe there is no restriction on the system path length, just search for cl.exe and make sure it is included in the system PATH.

Javax.imageio.ImageIO

Hello,
I have recently installed Fedora Core 2 to a dell dimension 8100 and I am trying to compile the program and get this error each time javac runs. error:
Class or interface `javax.imageio.ImageIO' not found in import.

Is linux installed with an sdk native to the system? If so how do I uninstall it? Would it conflict if I installed another Java SDK I found that the package jdk 1.5.0_05fcs was installed so I did a rpm -e command on it and reinstalled a fresh copy but this did not help. Thanks!-signol

Ok, I got this error
gcj: unrecognized option `-version'
gcj: no input files
I originally put j2sdk 1.4.2_09 on thinking there was no java to begin with, could this cause some of the errors? Also how would i go about uninstalling the package?-Signol

Using javax.imageio in JSP

Hi
I have a simple code snippet that I use to read in JPG/GIF image from a file and create a new image that is upside down . Here is my snippet.
//create upside down image
try {
String imgPath = "\\images\\AINCC.gif";
File fImg = new File(imgPath);
BufferedImage imgREG = ImageIO.read(fImg);
int iW = imgREG.getWidth(null);
int iH = imgREG.getHeight(null);
// Flip the image vertically and horizontally (equivalent to rotating the image 180 degrees)
AffineTransform tx = AffineTransform.getScaleInstance(-1.0,-1.0);
tx.translate(-iW, -iH);
//tx.scale(0.8,0.8);
AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
BufferedImage imgUSD = op.filter(imgREG, null);
// write flipped image to a file
File fUSD = new File("images\\USD_image.tmp");
ImageIO.write(imgUSD,"jpg",fUSD);
catch (Exception e) {
e.printStackTrace();
If I use this in a stand alone Java app it works fine but it will not work from the JSP page....
I have updated my server.policy file to give /images directory read, write, delete priviledges and I tried all the variations of the path (relative, absolute, direct....)...
I get the following error from the server log:

Can someone tell me what am I missing....
My JSP page is mailcard.jsp and images are under it in the images subdirectory....
Thanks
Amir

Hi,
Replace the following lines:
try{
String imgPath = "\\images\\AINCC.gif";
with
<%String contextPath = request.getContextPath();%>
try{
String imgPath = <%=contextPath%> + "\\images\\AINCC.gif";
You may also need to set the web application context root.

I'm using Eclipse version 3.3 and I've tried changing the network settings to use the proxy's hostname and port but this still isn't working. I've also tried using System.setProperty("http.proxyHost", "hostname") and System.setProperty("http.proxyPort", "port") but that hasn't worked for me either. Below is my class in full.

          catch (Exception e) {

}The error occurs with the line: BufferedImage image = ImageIO.read(url);
I have tried looking for a way to change how this specific method accesses the internet (e.g: a Proxy parameter with URLConnection) but there doesn't seem to be any.
Any help or suggestions would be greatly appreciated.
-Robert

Ah, that worked fine. I had thought of using that earlier but I was under the impression that the input stream would be HTML rather than an actual image. Not sure why.. Anyway, thanks very much for your help!
Here is the new code with your suggested revisions and a URLConnection to get the input stream:
import java.awt.image.*;
import javax.imageio.*;
import java.io.*;
import java.net.*;
public class ImageSave
    public static void main(String args[])
        try {
             // This is where you'd define the proxy's host name and port.
             SocketAddress address = new InetSocketAddress(hostName, port);
             // Create an HTTP Proxy using the above SocketAddress.
             Proxy proxy = new Proxy(Proxy.Type.HTTP, address);
             URL url = new URL("www.example.com/image.jpg");
             // Open a connection to the URL using the proxy information.
             URLConnection conn = url.openConnection(proxy);
             InputStream inStream = conn.getInputStream();
             // BufferedImage image = ImageIO.read(url);
             // Use the InputStream flavor of ImageIO.read() instead.
             BufferedImage image = ImageIO.read(inStream);
             ImageIO.write(image, "JPG", new File("image.jpg"));
        catch (Exception e) {

Problems with javax.imageio.ImageIO (cannot be resolved) *Urgent*

I was trying to import javax.imageio.ImageIO into my project but it cannot work... I am using Websphere Application 5.1.2 and using JDK 1.4.2_07... I try to import external jar containing javax.image but it still can't solve my problem... So can anyone help me... Thank alot...

There is no exception, the javax.imageio.ImageIO.read(InputStream input) method simply returns null, indicating that the stream can't be decoded with any of the registered ImageReaders.
BufferedImage bi = javax.imageio.ImageIO.read(new ByteArrayInputStream(wr2.getData()))
wr2 is of a class that I have written myself, and the method getData() returns a byte[] array consisting of the bytes previously read from the .gif-file...
there is nothing wrong with the data stored in the byte[] array, I have even compared it to the original file byte by byte... and it's all the same.
this works though:
BufferedImage bi = javax.imageio.ImageIO.read(new FileInputStream("img/iconOnlineDark.gif"))
Strange problem, in my opinion... but I'm not an expert in streams... so it might not be as strange as it seems to me...? Anyway, I must find a solution to this.

Javax.Imageio Help Needed!

Basically, I found a site with a Javax.Imageio applet used to take screenshots with the click of a button.
The problem is that I know nothing about compiling Java, and I would like some assistance. This applet is a necessary addition to a webpage gaming site browser (Basically it's a framed page which goes to the different game's servers to play the game) so that the users can easily take screenshots of what's happening in the game.
The example script they have is located at:
http://schmidt.devlib.org/java/save-screenshot.html
But I need it to be compiled and changed a bit... The output only allows output of one file, which isn't good... It saves as out.png, and rewrites over it if you go to take a 2nd screenshot. The problem with this is that many users will need to take multiple screenshots. I need this example applet changed to do something like "screen1.png" then "screen2.png" then "screen3.png", and so on... If possible, I'd like it to save to Desktop/Screenshots/screen(x).png
Could I get a bit of assistance?
Thanks a lot, I appreciate any help I could get VERY much.
Please post the finished applet if you're able to help as a response to here, preferably in the format of a zip or rar with the files inside.

If possible, I'd like it to save to Desktop/Screenshots/screen(x).pngDid you even read the documentation on that web page, or the source code itself? From the statements you made, it would appear that you didn't read it very closely. If that directory already exists (Desktop/Screenshots), you don't have to change the code to save files as you want them (it won't auto-increment the number, though--auto-incrementing would require a change).
When you have downloaded and installed the Java SDK, re-read the web page, and give the program a shot.

Tax jurisdiction 0 has incorrect length

Hi All,
I am getting following error whil posting billing document in to accounting.could any one suggest this how to resolve.(we are maintaining condition type UTXJ Value is zero)
ERROR;Tax jurisdiction 0 has incorrect length.

Hello;
Please be aware that if shipping from the US to a non juristiction
country the system should take a dummy jurisdiction code from the OBCL
transaction.
You have the situation that the product will be delivered from 'US'
to country 'BR'. If both countries are using the tax jurisdiction
functionality then it could be that the length is different in these
countries    as a solution in that export case the default tax
jurisdiction code from OBCL will be taken. Please check this.
Please also check the tax configuration in transaction FTXP.
Please ensure however that for each revenue line passed to accounting
that a tax line exists also otherwise error FF805 will be generated.
The tax code will be transferred to the conditions according to the
description of note 112609 - - therefore statistical items will not be
passed to accounting, and conditions with condition base value that is 0
are not passed to FI either.
IN SUMMARY:
-> There must be at least a revenue line for each tax line.
-> For each revenue line containing a certain tax indicator there
   must be a tax line with this indicator.
-> If a tax condition has base value = 0 OR is inactivated OR is
   statistical => then it is not passed to FI.
I hope it can help you.
Regards

Javax.jms.InvalidDestinationException: Destination has invalid type "class

Dear Sirs,
I am trying to send a JMS message from an application deployed to AS 10.1.3.3 to a destination (Queue), that was described with help of Oracle Enterprise Manager. This desination is working correctly if I send message from ESB by it's adapter. But my class refuses to execute method "createProducer": I have an exception:
"javax.jms.InvalidDestinationException: Destination has invalid type "class oracle.jms.AQjmsDestination" and cannot be used with OC4J JMS".
What is the case?
Thanks.

Thank You, Gera!
My mistake was: I tryed to use oficially registed QueueConnectionFactory. But, indeed, AS notes that "connection factories are only needed for in-memory and file based persistence destinations. Destinations that use database persistence do not require connection factories to be specified - these are created dynamically by the JMS connector (adapter) used for database persistence."
So, I found ra.xml file in directory of generated adapter, fetched queue factory name that seems correct for me, and use it.
Now it works!
Спасибо, Гера.

Javax.imageio.IIOException: Can't read input file!

That is the error I get every time I try to run the .jar file. Yet when I run it in the compiler it works just fine. I'm not sure what to make of this, here is the code any help you can provide will be appreciated.public void setGraphic(String image) {
        String fileLoc = getClass().getResource("/com/siteName/Graphics/" + image).getPath();
        try {
            fileLoc = URLDecoder.decode(fileLoc,"UTF-8");
        } catch (UnsupportedEncodingException ex) {
            ex.printStackTrace();
        File file = new File(fileLoc);
        try {
            this.image = ImageIO.read(file);
        } catch (IOException ex) {
            ex.printStackTrace();
}

Is your image in the jar? If so, use URL, not File:
URL url = getClass().getResource("/com/siteName/Graphics/" + image);
this.image = ImageIO.read(url );

Does SSL or HTTPS has some length limitation ?

Hei :)!!!
I am using an https protocol in order to send in a safe way a contanance of a form which contains information like user credit card number, his details and etc.
The problem is that when i am sending this form by HTTP protocol the form is being sent correctly, but when i am sending it by HTTPS some form fields contenense are lost.
My question is: does HTTPS or SSL protocols has some size limitation on the information that is being sent by them?
Does some one dealed whith this kind of problem? help me:( i am quite desperate:(

there is no any size limitation for this.U can send as much length of data.BTW which API r u using for the SSL comm'n.

Need to download a file which si space delimted and has fixed length char

Hi,
I have a custom report which downloads an output file in text format.I need the contents to be space delimited.My file data contains numbers as well as characters.I ahve pased the parameter WRITE_FIELD_SEPARATOR = ' ' in the FM.Hwoever the space is introduced only oif the column value is a character.If its a number/digit,the columns are not seperated by space.
Now my data appears like that:

DO I need to pass any additinal parametre?Also for fixed length characrets,do i need to pack/unpack data before passing to the FM ?

Bad index in constant pool #1 Code segment has wrong length

java.lang.ClassFormatError: nz/net/quickstep/uiobjects/Cba2efkSflctl (Bad index in constant pool #1)

From your code..
Here is a suggestion
try {
for (int i=0; i<b.length; i++) b[ i ]=0; // zero the array
Class c = defineClass(name, b, 0, b.length);
} catch (ClassFormatError cfe) {
System.out.println("Error trying to load class "+name); //print the name....
for (int i=0; i<b.length; i++) b[ i ]=0; // zero the array
Class c = defineClass(name, b, 0, b.length);This make all bytes to '0'. So how would it create class??

Class javax.faces.el.ValueBinding has been deprecated

I am trying to re-write the following code using ValueExpression which has re-placed ValueBinding. But I can't seem to get it to work. Please help. Thanks for any help
    public String editLinkAction()
            /* pull out the currently selected service request */
            Requests editReq =
            (Requests)this.getDataTable1().getRowData();
            FacesContext ctx = FacesContext.getCurrentInstance();
                ValueBinding binding =
                ctx.getApplication().createValueBinding("#{backing_req_Request2.requests}");
                binding.setValue(ctx,editReq);
                return "reqDetail";
        }

The method name editLinkAction() suggests that you rather need a MethodExpression instead of ValueExpression, is this true?
Anyway, you can find here examples:/**
* Create ValueExpression object based on the given value expression string and value type.
* This is to be used in UIComponent#setValueExpression().
* @param valueExpression The value expression string, e.g. "#{myBean.someValue}".
* @param valueType The actual value object type, e.g. String.class.
* @return The ValueExpression object to be used in UIComponent#setValueExpression().
private ValueExpression createValueExpression(String valueExpression, Class<?> valueType) {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    return facesContext.getApplication().getExpressionFactory().createValueExpression(
        facesContext.getELContext(), valueExpression, valueType);
* Create MethodExpression object based on the given action expression string and return type.
* This is to be used in UICommand#setActionExpression().
* @param actionExpression The action expression string, e.g. "#{myBean.action}".
* @param returnType The actual return type of the action, e.g. String.class or null (void).
* @return The MethodExpression object to be used in UICommand#setActionExpression().
private MethodExpression createActionExpression(String actionExpression, Class<?> returnType) {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    return facesContext.getApplication().getExpressionFactory().createMethodExpression(
        facesContext.getELContext(), actionExpression, returnType, new Class[0]);
}Use examples:dataTable.setValueExpression("value", createValueExpression("#{myBean.dataList}", List.class));
saveButton.setActionExpression(createActionExpression("#{myBean.saveDataList}", String.class));
