Awt.toolkit returns null

Hi all, I've discovered that the awt.toolkit system property returns null on the linux server hosting a java web application am working on. I've listed some of the AWT system properties on the system but the awt.toolkit returns null.
java.awt.graphicsenv: = sun.awt.X11GraphicsEnvironment
java.awt.headless: = ture
awt.toolkit: = null
I really dont know what could be causing this.
This affects all image related proceses (dynamic image creation) that the application does. It outputs the following error message:
java.lang.NoClassDefFoundError
     java.lang.Class.forName0(Native Method)
     java.lang.Class.forName(Class.java:141)
     java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:62)I dont think it has anything to do with X11, XServer or Headless.
Any thoughts ?
Cheers

It hs something to do with a missing X11 server/the machine being headless. I faced a similar problem recently.

Deprecation warning for getFontMetrics(java.awt.Font) in java.awt.Toolkit

Hi all,
When I use the following code
JComponent c;
FontMetrics metrics = getToolkit().getFontMetrics(c.getFont());
I get this following warning during compilation:-
warning: getFontMetrics(java.awt.Font) in java.awt.Toolkit has been deprecated
JDK suggests to use getLineMetrics() of the Font class.
But there's an issue with that: if I use getLineMetrics(), there is no API method that I can use to get the width of a string as opposed to FontMetrics which provides stringWidth(String str) method for that purpose. In fact all the methods in FontMetrics are not mapped into LineMetrics.
Could anyone please help or provide me at least some pointers on how to tackle this issue so that I can get rid of the deprecated method along with the existing methods mapped to equivalent APIs? The bottomline is that I should be able to maintain the existing functinality of my application for those part of code that uses getToolkit().getFontMetrics().
Thank you for your help in advance.
-Sanjoy Das

Use Graphics.getFontMetrics(font) instead.
After creation your frame and calling frame.show();
You can access it like that
frame.show();
frame.getGraphics().getFontMetrics(new Font("Arial",0,10));
before showing graphics is null.
Or just create a BufferedImage and ask it for graphics.
BufferedImage img=new BufferedImage(...);
img.getGraphics().getFontMetrics(font);

Hmm....
some of that looks very familiar to me :-)
http://forum.java.sun.com/thread.jspa?forumID=28&threadID=570463
1. post your code wrapped in code tags and it'll display it nicely.
2. post to the Java Media Framework topic,
I haven't tried JMF within an applet.
Have you tried getting it working in an application first ?
That should simplify your debugging to start with.
I suspect the Player hasn't started yet, or isn't in a realised state.

Quality of Cursors created with java.awt.Toolkit(createCutsomCursor)

Hi -
I encountered a small problem while creating my own cursors for my Java application , I used the java.awt.Toolkit Objects createCustomCursor method to use a .GIF image as a cursor ... it worked but the quality of that cursor is horrible, the outline is rough ... I tried the same with a transparent PNG file afterwards unfortunately the same result , does anyone know why the quality is that bad or may this just be a problem of the choosen color pool ?
Help would be very appreciated since I have no clue how to use .cur files ... seems like a non supported format , in case someone knows how to import those it would help a lot if you would drop some lines of code.
I am currently using Java 2 SDK 1.4.0_01 , newest version.
Thanks for you time and thanks in advance for possible answers
-- Harald Scheckenbacher

I noticed this problem too. It looks like the routine is generating cursors which are scaled to to the maximum size of the system. On my win XP system,
Dimension dim = toolkit.getBestCursorSize(256, 256);
int maxColors = toolkit.getMaximumCursorColors();
return 32,32 and 256 respectively
If I provide a 16x16, all the pixels have been pixel doubled. If I specify a 32x32 image, then the cursor looks perfect. This looks like a bug for the java folks. Not sure why someone would ever want a cursor image to be pixel scaled.

Problems with awt.Toolkit on Tomcat

Hello! I'm trying to get the Default Toolkit (java.awt.Toolkit.getDefaultToolkit() ) to determine the scrren size of the client, and Tomcat keeps throwing an Exception - now it's the website's Tomcat and the one on my localhost - there it worked.. Is there another way to determine the client's screen size in JSP (not JavaScript!)?? Thanx!

first, the previous poster was right - learn how these protocols are interacting before you try something like you want to do - and they're right, you can't use the AWT toolkit to find out ANYTHING about the client.
HTTP is stateless. so it's like this:
browser request -> your code on server, jsp completely exeutes, generates html -> html PLAIN old html goes to the browser. in that order. no exceptions. ergo, all your code has executed once the browser starts getting data (buffers on the server not withstanding).
As to why you're getting the exception, the server you are trying to run it on is most likely running in a mode called "headless", that is, there is no windowing api available to the JVM, so any awt calls will fail anyway. It works on your box because you are probably running a full windowing os, such as windows or Linux with gnome or kde. it just happens to return the correct screen size because that's the screen size of your screen, not the screen of the browser that it's outputting to. (try running your code locally and making your browser window small, you'll be dismayed that the rendered HTML is not the "right" size - because the screen size call was based on your resolution, NOT the size of the requesting browser window.
if the last 2 sentences don't make sense, re-read them until they do.
best of luck, sorry you're learing these frustrating lessons this way.

Substitute of java.awt.ToolKit.getDefaultToolKit.beep()

Hello everybody. I am designing a Swing Application and there I am using java.awt.ToolKit.getDefaultToolKit.beep() method to generate sound in various operations.

How to prevent setBoundingThemes returning null MBR when no data are found

I am using setBoundingThemes method in MapViewer bean to zoom in to query results in a JDBCTheme. It is possible however that the JDBCTheme doesn't contain any data when no rows match the criteria. The result is that the other themes are queried without a filter and the overall map size is used (as the result of the mbr of all themes). This wouldn't be a problem if the theme_min_scale was considered, but it isn't, so all available data are rendered and this takes quite a while. Is there a way to set an alternative query window which will be used in case no rows are returned?
To show the difference:

and after that the mbr is made up out of all themes, resulting in a map of all available dataThu Jun 09 19:56:19 CEST 2005 FINEST [oracle.sdovis.MapMaker] mbr of all themes: java.awt.geom.Rectangle2D$Double[x=-0.5,y=-2.6605568400000004,w=11.025,h=58.665278322000006]
Of course I could query the database first to find out if there are any geo data available, but I am hoping there's another way. Anybody who can help?
Regards,
Ida

Hi Ida,
I think just the size parameter with null mbr for the bounding theme won't help too much.
We would need a reference point to be used with this size. This point we could get if we query the other themes, but as we don't have a reference mbr (the bounding theme mbr is null) this would be a full query on the other themes.
We will discuss your suggestion of not rendering any theme and raising an exception if the mbr for the bounding theme returns null.
Thanks.

ImageIcon.getImage() returning null

Hi,
I have a class, say ABC, which extends ImageIcon....when I do .getImage() ...its returning null...any idea why? I know the ABC icon exists, b/c i can add it to a JLabel and see it...but when I do getImage its null...

JComponet.getName() returning null

I have various component. on JPanel.One of them is given some name using componet.setName("xyz").
I have to perform Action in fousListener focuslost event depending on e.getComponent.getName()

}Based on above code I have following scenario
"button2 " should toggle frame (show/hide) and change text of button2 accordingly
button1 should bring the Jframe containing JTable
whenever Jtable looses focus.It should hide frameand text of of button2 should become "showResult"
But afte Button2 looses focus and TextField1 gains focus .Frame doesnt hide ?

EjbFindByPrimaryKey returns null

Hello,
We are writing an BMP in 6.1 SP 2. The ejbLoad perfectly loads the data.
From the Remote using the getPrimaryKey() to get the PrimaryKey. That key
is passed to the findByPrimaryKey(PK) call. But, it returns the following.
I have the db-is-shared to false in weblogic-ejb-jar.xml. It looks like it
is returning null and I don't understand why it is doing like this. Whether
it is because, it is not able to find the object through the
findByPrimaryKey or I am making any mistakes.
I even system.out.println inside the ejbFindByPrimaryKey and the key is not
null, it is having the value. Any help is greatly appreciated.

Sentence fragments.
Missing predicates.
It's a bit hard trying to understand your questions.
In BMP you write the ejbFindByPrimaryKey method. Your job in that method is
to verify that it exists in the DB and throw an ObjectNotFoundException if
not. You return the valid PK (the one passed in) if it does exist. So, what
exactly is returning null?

FindNode returning Null And XML Not Accepting Special Characters

Hi All,
i am trying the get the attribute value in the element "ns4:InfoCFDi" using FindNode method, but the method is returning NULL. I used the same code for other sample as well and was successfull. but for this specific XML file(which is below) I am getting a Null.
i can get till S:Body, but when i try to use FindNode for ":Body/s4:ResponseGeneraCFDi" I get Null value.
And I used "S:Body/*[local-name()=" | "ns4:ResponseGeneraCFDi" | "]";
as mentioned in other post but still no success.
==>I Have one more question relating to special characters. I need to use characters such as - ó in my XML to read as well as write. When I try to read i am getting XML parse error and when writing, i cannot open the file properly.
Your help is much appreciated.
My code is here:
Local XmlDoc &inXMLDoc, &reqxmldoc;
Local XmlNode &RecordNode;
&inXMLDoc = CreateXmlDoc();
&ret = &inXMLDoc.ParseXmlFromURL("D:\Agnel\Mexico Debit Memo\REALRESPONSE.xml");
If &ret Then
&RecordNode = &inXMLDoc.DocumentElement.FindNode("" );
If &RecordNode.IsNull Then
Warning MsgGet(0, 0, "Agnel FindNode not found.");
rem MessageBox(0, "", 0, 0, "FindNode not found");
Else
&qrValue = &RecordNode.GetAttributeValue("asignaFolio ");
Warning MsgGet(0, 0, "asignaFolio." | &qrValue);
End-If;
Else
Warning MsgGet(0, 0, "Error. ParseXmlString");

First of all you have to supply a value you want to search for and this has to be the complete path to the value. You're saying you already tried that, but can you paste the code which you used for that? I don't see the path mentioned in the code you posted.
*FindNode*
Syntax
FindNode(Path)
Description
Use the FindNode method to return a reference to an XmlNode.
The path is specified as the list of tag names, to the node that you want to find, each separated by a slash (/).
Parameters
Path
Specify the tag names up to and including the name of the node that you want returned, starting with a slash and each separated by a slash (/). This is known as the XPath query language.>
Another option would be this snippet of code:
&InfoCFDiArray = GetElementsByTagName("ns4:InfoCFDi");
&InfoCFDiNode = &InfoCFDiArray [1];
&attValue = &InfoCFDiNode.GetAttributeValue("noCertificadoSAT")
Warning(&attValue);
It creates an array of XML Nodes which match the name "ns4:InfoCFDi". Since there's only one in the XML it's safe to assume it will be the one and only node in the array. I've assigned that node to the variable &InfoCFDiNode and use that to retrieve the attribute "noCertificadoSAT" value. The warning message should display the value supplied there.
Concering the special characters; you will have to change the encoding of the XML. Peoplecode sets this to UTF-8 by default, but doesn't include this in the header. There's a little hack for that somewhere on the web, I'll see if I can find it.

Kff.where returns 'null' and causes sql error - looking for a work around

Hello,
I am using BI 5.6.3 in EBS (11.5.10.2)
I have created a kff.where as follows:
<lexical
type="oracle.apps.fnd.flex.kff.where"
name="lp_location_where_clause"
comment="Comment"
application_short_name="OFA"
id_flex_code="LOC#"
id_flex_num=":lp_location_flex_structure"
code_combination_table_alias="loc"
segments="ALL"
operator="BETWEEN"
operand1=":p_location_low"
operand2=":p_location_high"/>
</lexicals>
Everything works fine, as long as I have a values for the p_location_low and p_location_high. However, this is a parameter that comes in from a concurrent program and is optional. When the user doesn't pick a value, :p_location_low is the concatenated delimiters for the location '..'.
When this runs, the kff.where is returning null which causes 'Invalid Relational Operation error' because 'AND null' is not valid.
Warning in the log is :[091910_025232517][][STATEMENT] !!Warning: FlexAPI returns null for 'x_where_expression' lexical definition...
Does anyone have a workaround for this since making the parameter required is not an option for my users?
Thanks for reading.

In your SQL*Plus session, make sure you
SQL> set define offbefore trying to create the Java stored procedure. SQL*Plus assumes that any string that begins with an & is a substitution variable unless you tell it that you have no substitution variables (via set define off).

HelpSet.findHelpSet() returns null, and trapping ID errors

I was having a problem initializing JavaHelp. HelpSet.findHelpSet() was returning null. I searched the forum, and found it was a common problem, but the answers were unhelpful. The answers pointed to a problem with CLASSPATH, but offered little in the way of advice for a newbie like myself on how to deal with it.
A second issue concerns HelpBroker.enableHelpOnButton(). If you feed it a bogus ID, it throws an exception, and there's no way to trap it and fail gracefully. JHUG doesn't provide much in the way of alternatives.
Now, having done a bit of research and testing, I'm willing to share a cookbook formula for what worked for me.
I'm working in a project directory that contains MyApp.jar and the Help subdirectory, including Help/Help.hs. My first step is to copy jh.jar to the project directory.
Next, in the manifest file used to generate MyApp.jar, I add the line:
    Class-Path: jh.jar Help/I'm working with Eclipse, so in Eclipse, I use Project - Properties - Java Build Path - Libraries to add JAR file jh.jar, and Class Folder Tony/Help
I define the following convenience class:
public class HelpAction extends AbstractAction
    private static HelpBroker helpBroker = null;
    private String label = null;
    public HelpAction( String name, String label )
        super( name );
        this.label = label;
    public void actionPerformed( ActionEvent event )
        displayHelp( label );
    public static boolean displayHelp( String label )
        if ( helpBroker == null )
            Utils.reportError( "Help package not initialized!" );
            return false;
        try
            helpBroker.setCurrentID( label );
            helpBroker.setDisplayed( true );
            return true;
        catch ( Exception e )
            Utils.reportError( e, "Help for " + label + " not found" );
            return false;
    public static boolean initialize( String hsName )
        URL hsURL = HelpSet.findHelpSet( null, hsName );
        if ( hsURL == null )
            Utils.reportError( "Can't find helpset " + hsName );
            return false;
        try
            HelpSet helpSet = new HelpSet( null, hsURL );
            helpBroker = helpSet.createHelpBroker();
        catch ( HelpSetException e )
            Utils.reportError( e, "Can't open helpset " + hsName );
            return false;
        return true;
}If you use this class in your own code, you'll want to replace Utils.reportError() with something of your own devising.
Finally, in my GUI class, I use the following:
    JPanel panel = ...
    JMenu menu = ...
    JToolbar toolbar = ...
    HelpAction.initialize( "Help.hs" )
    Action gsAction = new HelpAction( "Getting Started Guide", "gs.top" );
    menu.add( gsAction );
    JButton helpButton = new HelpAction( "Help", "man.top" );
    toolbar.add( helpButton );
    InputMap imap = panel.getInputMap( JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT );
    imap.put( KeyStroke.getKeyStroke( "F1" ), "F1help" );
    ActionMap amap = panel.getActionMap();
    amap.put( "F1help", new HelpAction( null, "man.top" ) );

Sorry, the sixth-from-last line of my example should read,
    JButton helpButton = new JButton( new HelpAction( "Help", "man.top" ) );

Why does getParameter("uri") returns null ???

Hi !
JAVA can be rather frustrating and I have run of of dukes. How about IOU ?
Unfortunately none of the previous questions in the db shed light on my problem.
I am trying to get at the "uri" and I have the following code fragment :
package com.developer;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.io.PrintWriter;
public class proptest extends HttpServlet
public void doGet( HttpServletRequest req, HttpServletResponse resp)
    throws ServletException, IOException
    PrintWriter out = resp.getWriter();
    out.println("Parameter Name: " + req.getParameter("uri"));
public void init() throws ServletException
    // initialie the servlet here. Use ServletConfig object to get
    //    initialization parameters...
    ServletConfig config = getServletConfig();
    // ... more stuff ...
}

Hi!
In case anyone stumbles upon this in the database, I worked aroung it by using req.getRequestURI().
However I still do not know why getParameter() returns null. It would be useful e.g. if you want to display a list of all request params e.g.:
// stub code follows...
java.util.Enumeration enum = rea.getParameterNames();
while (enum.hasMoreElements())
String name = (String) enum.nextElement();
System.out.println("Parameter "+name + " " + req.getParameter(name))
...For me, nope, all nulls. If it works for you , do tell me.
Also if you look at the "bugs db" there seems to be a number of issues concerning getParameter().

Why ResultSet getDate() method returns null when querying .csv file?

Here is the full code:
import java.sql.*;
import java.sql.Types;
import java.sql.Date;
import myjava.support.CachedRowSetMaker;
import javax.sql.rowset.CachedRowSet;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
class jdbc2{
final private String s1="SELECT top 10 [DATE], [ADJ CLOSE] FROM [vwo-1.csv]";
private ResultSet result=null;
private Connection conn=null;
public static void main(String[] args) throws SQLException{
jdbc2 db=new jdbc2();
try {
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          db.conn = DriverManager.getConnection("jdbc:odbc:STOCK_DATA");
          PreparedStatement sql=db.conn.prepareStatement(db.s1);
          db.result=sql.executeQuery();
// check column names and types using the ResultSetMetaData object.
          ResultSetMetaData metaData = db.result.getMetaData();
     System.out.println("Table Name : " + metaData.getTableName(2));
     System.out.println("Field\t\tDataType");
     for (int i = 0; i < metaData.getColumnCount(); i++) {
     System.out.print(metaData.getColumnName(i + 1) + "\t");
     System.out.println(metaData.getColumnTypeName(i+1));
     System.out.print(metaData.getColumnName(1) + "\t"+metaData.getColumnName(2)+"\n");
          while (db.result.next()){
               System.out.print(db.result.getDate("DATE", Calendar.getInstance()));
               System.out.format("\t%,.2f\n", db.result.getFloat("Adj Close"));
catch (Exception e) {
System.out.println("Error: " + e.getMessage());
     finally {
          db.result.close();
          db.conn.close();
Everything works well, until getting to the block
          while (db.result.next()){
               System.out.print(db.result.getDate("DATE", Calendar.getInstance()));
               System.out.format("\t%,.2f\n", db.result.getFloat("Adj Close"));
The getDate("DATE", Calendar.getInstance())); always returns null, instead of the date value in the vwo-1.csv.
Even though I change it to
java.sql.Date d=db.result.getDate("DATE") and convert to String using .toString(), I still gets nulls. The dollar amount in "Adj Close" field is fine, no problem.
The .csv fils is downloaded from YahooFinace.
Can anyone review the code and shed some light as to what I did wrong?
Thanks alot.
