Whats wrong with this code? Error 1180.

I keep getting the error 1180:Call to a possible undefined method getURL
var jscommand:String = "window.open('www.adobe.com','win','height=1024,width=768,toolbar=no,scrollbars=yes');"; getURL("javascript:" + jscommand + " void(0);");
Any help would be appreciated.
Thanks guys.

Got it.
Thanks!

Can you guess whats wrong with this code snippet? Perhaps its too easy...
private void clearDefaultTableModel( DefaultTableModel dtm) {
        int rowCount = dtm.getRowCount();
        for(int i =0; i < rowCount; i++) {
            dtm.removeRow(i);

private void clearDefaultTableModel(
DefaultTableModel dtm) {
int rowCount = dtm.getRowCount();
for(int i =0; i < rowCount; i++) {
dtm.removeRow(i);
it should be
private void clearDefaultTableModel(DefaultTableModel dtm) {
   int rowCount = dtm.getRowCount();
   for(int i =0; i < rowCount; i++) {
     dtm.removeRow(0);
}or another way
private void clearDefaultTableModel(DefaultTableModel dtm) {
while(dtm.getRowCount()>0){
     dtm.removeRow(0);

Thank you. How do i amend this? I have defined value1though.Yes, you did - but after the call to addFocusListener(...). It needs to be before it.
BTW, you did the same thing with "value2.addFocusListener(this)" and "sum.setEditable(true)" on the next two lines. You're attempting to call a method on an object that doesn't exist yet (i.e., you haven't called new yet).

same... i am not very experienced, and try and uses this as training... but as new to java programming i could still mention about 5 things that might be wrong with this code... so a deeper explanation would be nice...
while(true) { } for example seems like a nice way to make infinite loop that can suck your memory out of your computer pretty fast :-) newb

Whats Wrong with this code? URLReader

Ok, so I have this URLReader.java program. It goes to a specific website, I put in a project ID. It pulls up a project. I can then "Scrape", "Extract Data from the URL and put them into variables. I then upload the variables into the DB.
I've used this code over and over again and it works, but I seem to have a problem with the second part of the code.The error message that I get is:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
Please note the URL is a fake one. I did not want to give the real URL. I have provided the String to read, which is actually HTML code. I thought it might be the "Researchers(s):" string that it does like, maybe a problem with "(s), but I dont know?
First part of the code: This really gets a project ID from a collection and iterates throught the collection with each project ID.
String projectId = "87023";
            java.net.URL projectDetails = new java.net.URL("http://someSite.com/portfolio/ProjectDetails.asp?Source=Tracking&Key="+projectId);
            java.io.BufferedReader in =
                        new java.io.BufferedReader(new java.io.InputStreamReader(projectDetails.openStream()));
            String projDetailspage = new String("");
            String inputLine = "";
            while ((inputLine = in.readLine()) != null)
                projDetailspage = projDetailspage.concat(inputLine.trim());
            System.out.println("project ID: "+ projectId);
Second Part of the Code:
String str = (projDetailspage.split("\\<[Bb]\\>Researcher(s)\\</[Bb]\\>") // look for: <b>Researcher(s):</b> , also the part of code I am having problems with.
            [1].split( "\\<td\\>")[1].split("\\</table>")[0].trim());   //put everything into a variable call str from the <td> to the </table> tags
            System.out.println("String before replace all: "+ str);

I ran your program and it works great. This is the output I get. This is for a project that had 4 researchers, that is not always the case.
investigator1 = r. Michael E. Welge
investigator2 = Dr. Albert J. Valocchi
investigator3 = Dr. Barbara Ann Bailey
investigator4 = Dr. David E. Goldberg
for some reason I loose the D in Dr. for the first Investigator.
also, I know I need to modify my code to find out how many researchers there are. I then place them into the correct variable.
example
researchers String that your code works on: None Found</font></td></tr><tr><td width="30%" align="right" valign="top"><font size="-1"><b>Student(s):</b></font></td><td width="70%" align="left" valign="top"><font size="-1">Dr. Terry Hogan, Pennsylvania State University</font></td></tr><tr><td width="30%"><font size="-1"></font></td><td width="70%" align="left" valign="top"><font size="-1">Dr. Chengyu Shen, Pennsylvania State University</font></td></tr><tr><td width="30%"><font size="-1"></font></td><td width="70%" align="left" valign="top"><font size="-1">Dr. Anne Pifer, Pennsylvania State University</font></td></tr>
investigator1 = one Found|Student(s):|Dr. Terry Hogan // should be None Found.
investigator2 = Dr. Chengyu Shen
investigator3 = Dr. Anne Pifer
npe errorjava.lang.ArrayIndexOutOfBoundsException: 3
The logic should be, when I scrape between tags, if it should be "None Found" then skip to the next project ID , also, each project may have as many as 0, 1, 2, 3, 4 researchers. but no more than 4
So I thought of doing an:
If( researchers == 2)
    investigator1 = investigator[x];
    investigator2 = investigator[x];
}etc...
Thanks again.
if you need me to email you the code. my email addres is [email protected]
I know I am not that talented of a programmer, but I am learning, and trying all the time. I want to do this the correct way, but I am not always sure which way that is. I usually try a class Diagram and go from there, but I have had some trouble with this one. If you need more of an explanation then email me.

Can understand whats wrong with this code.

I'm sort new to Java programing, and I created this simple converter, but when I try to complie it, it gives me an exception error, could some one tell me how to correct this code.

           double US= 0.0;
           DecimalFormat twoPrecision = new DecimalFormat("0.00");
         input() = 0
          try{
               US = Double.parseDouble (input);
                System.out.print("US to Euro: ");
                System.out.println(twoPrecision.format(US * EURO));

Whats wrong with this code?

Hi Dan, if you want to use a RETURNING parameter when you call you method, you need to define the parameter as a RETURNING parameter in your class definition.
    METHODS get_data RETURNING VALUE(e_data) TYPE char20.
You had defined it as an EXPORTING parameter, which means that when you call the method you would have need to use this syntax instead.
   object_reference->get_data( IMPORTING e_data = var ).

Passing events - whats wrong with this code?

hi,
I'm trying to get components to behave in a frame like they would as though I had written
frame.getContentPane().add(thecomponent);
by processing events explicitly. I've written the code below as a test, and it does work, but the events do not seem to be passed to the component at the right level.
For example, when the JTree is the component tried it does not expand nodes when you click on them.
Or if you tree a JButton then it doesn't actually visibly "click"
I'm still quite new with Swing so any help would be really appreciated - is this kind of thing even possible?
thanks,

Sorry
It doesn't compile.
I'm not sure how to create the 6 processes to each add part of sum and then update the total for the next processor to sum the next part up, and i don't know where it goes either.
I think it would be something like:
public void run()
try
//this add it up
total= array + total;
System.out.println("PROCESSOR"+thisnumber+" Your total is " + total);
sleep();
update(total)
and then do the same code for another processor.
I'm confused do I have to name each processor and put the name in :
public void Processor1 ()
please help I'm very confused
}

Please tell me whats wrong with this code for sendRedirect

</html>I am trying to set an attribute in the request object (attribute name is temp). But in the jsp it is not getting the value of the attribute. The request is not getting transferred. Please let me know what correction is needed.
I have used RequestDispatcher as well but in that case the control doesnt go the jsp when i used sendRedirect the control goes only if there isnt any request.getattribute in the JSP page.
Thanks
Nikesh

You can;t transfer the request object using response.sendRedirect;
Use RequestDispatcher to transfer the request object into another page.
For Example:
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(viewName);
            dispatcher.include(req, resp);

What is wrong with this code? on(release) gotoAndPlay("2")'{'

Please could someone tell me what is wrong with this code - on(release)
gotoAndPlay("2")'{'
this is the error that comes up and i have tried changing it but it is not working
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 2: '{' expected
     gotoAndPlay("2")'{'
Total ActionScript Errors: 1 Reported Errors: 1
Thanks

If you have a frame labelled "2" then it should be:
on (release) {
    this._parent.gotoAndPlay("2");
or other wise just the following to go to frame 2:
on (release) {
     this._parent.gotoAndPlay(2);
You just had a missing curly bracket...

I can't figure out what's wrong with this code

First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.

What the he** is wrong with this code?

Hi,
I have 2 tables. Primary table "resease" and secondary table (containing the foreign key) "kunden".
Selecting a release (dropdownlist), will show you the corresponding entry of kunden (datatable).
I added buttons to the datatable for deleting certain rows. This all works fine so far.
But as you are going to delte the last entry of table kunden, I want to delte the corresponding entry of the table release as well. And by trying to do so, I get an exception telling in line "dataTable1Model.commit();"
"java.sql.SQLException: Lock time out; try later."
The exception disappears by deleting the inner try-catch block.
So what is wrong with this code?
Thank,
Mark.
PS: If you need the database-schema or anything else, let me know....
public String delete_action() {
        try {
         //returns -1, so I can't use it
            int rowCount = dataTable1Model.getRowCount();
         //get affected row
            com.sun.jsfcl.data.DataCache.Row row =
            dataTable1Model.getDataCache().get(dataTable1Model.getRowIndex());
            row.setDeleted(true);
            try {
                //New RowSet for getting FK of affected line
                JdbcRowSetXImpl pkRowSet = new JdbcRowSetXImpl();
                pkRowSet.setDataSourceName("java:comp/env/jdbc/AVT");
                pkRowSet.setCommand("SELECT fk_idrelease FROM kunden " +
                "where fk_idrelease = ?");
                //Convert Row into string
                String myRow = row.toString();
                //Getting the index of the first "=" (it's before the FK)
                int index = myRow.indexOf("=")+1;
                //Getting the number (FK) out of the string an casting it to int
                int fk = Integer.parseInt(myRow.substring(index,(index+1)));
                //Saving the FK in SessionBean1, so I can use it a parameter of
          //the setObject(int, Object)-method
                getSessionBean1().setFk(fk);
                //this will give me a RowSet of all lines containing the FK of
          //the affected row
          pkRowSet.setObject(1, getSessionBean1().getFk());
                pkRowSet.execute();
                pkRowSet.last();
                int numRow = pkRowSet.getRow();
          //If the numRow (numbers of rows) is 1, go to cascade_delte
          //and delte the entry with primary key as well
                if (numRow == 1) {
                    cascade_delete(); //not implemented yet
            }catch (Exception ex) {
                error("Error counting affected rows: " + ex);
            dataTable1Model.commit();
            dataTable1Model.execute();
            info("Deleting row OK!");
        }catch (Exception e) {
            log("Page 1: Row delete exception: ", e);
            error("Error during deleting: " + e);
        } // end try catch
      return null;
    }

just a guess - perhaps call pkRowSet.close() at the end of your try/catch?
