'Undefined' Error with PHP and AJAX

I have spotted it - it is a typo in responseAjax - I have typed reponseText insteam of responseText.

That is several hours of my life that I won't get back

Never mind - and thanks for the heads up about Firebug, it looks quite useful

'Undefined' Error with PHP and AJAX

Status of 200 and a Status Text of OK - not sure what to do with Firebug - still just getting 'undefined' as the responseText.

'Undefined' Error with PHP and AJAX

Hi

That is the problem - it just says 'undefined' in the response. I will have a look at firebug if you think that it is useful.

kind regards

'Undefined' Error with PHP and AJAX

Hi

Having problem with a simple AJAX call, I just keep getting an undefined error when I run this. I have checked the PHP file (getClassCodes.php) and that returns
data as it should, and I can see that working in the HTTP monitor in Netbeans, but when it goes to get the reponse - I just get 'undefined'.

Here is the simple PHP page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
<script>
includeJS("../javascript/core_javascript.js");
var myRequest;
function getClassCodes(teacherId){
myRequest = getXMLHTTPRequest();
var url = 'getClassCodes.php?teacher_Id=' + teacherId;
var myRandom = getRandomNumber();
myRequest.open('GET',url + '&rand=' + myRandom,true);
myRequest.onreadystatechange = responseAjax;
myRequest.send(null);
}
function responseAjax(){
if(myRequest.readyState==4){
document.getElementById('classTable').innerHTML = myRequest.reponseText
}
}
function test(){
alert("Hello");
}
function includeJS(jsFile){
var js = document.createElement("script");
js.setAttribute("type","text/javascript");
js.setAttribute("src",jsFile);
document.getElementsByTagName("head")[0].appendChild(js);
}
</script>
</head>
<body>

<div id="classTable">
<b>Data should be here</b>
</div>
<form id="f" method="post" action="">
<input type="button" name="btn1" value="click" onclick="getClassCodes('matt')"/>
</form>
</body>
</html

and here is the JS file that I am using:

Please can anyone help.

kind regards

FOP and SVG Files

Hi again

I feel that I have made progress (by getting the URL right) but it is still not right. By using the FOP below I can now see the image starting to render (just see the top left hand corner) in the PDF. Its quality looks good but there is only a small amount of it there.

I can view the whole svg image in my Safari web browser.

Is there some fo:external-graphic attribute that I should be setting ?

The semi working fo is below (where graph_img1 is the svg file):

many thanks again

FOP and SVG Files

Thanks for this, good advice , I think that this has moved me forward. I am now getting another error indicating that it is trying a bit harder to show this image. It is too late to investigate this now, I will pick it up again tomorrow.

The error is ...

SEVERE: svg graphic could not be built: file:C:/Work/...0_graph01.svg:-1
An I/O error occured while processing the URI:
"file:C:/Work....0_graph01.svg#clipPath1"
specified on the element <rect>

FOP and SVG Files

Thanks for the reply, but I cannot find examples of what I want to do.

I am trying to create a PDF report that has a graph at the top and a table of data underneath. I generate the Graph and the rest of the report XML in java and then pull them together in a PDF with FOP and XSLT.

At first, i used a jpeg for the graph (created by JFreeChart) and I could add that using fo:external-graphic. However, the graph was blurred so I decided to try and use SVG as I can create an SVG file from JFreeChart.

If I do this with the SVG file, where $graph_img1 is my .svg file:

I get :

[Fatal Error] :1:40: Invalid encoding name "Cp1252".
22-Jul-2008 19:56:06 org.apache.fop.image.analyser.ImageReaderFactory make
WARNING: No ImageReader found for file:C:/Work........graph1.svg

If I try and do this where svgString is the whole svg XML starting from <svg....

I get

Error(Unknown location): fo:instream-foreign-object is missing child elements.
Required Content Model: one (1) non-XSL namespace child

Have you got any suggestions.

Many thanks

FOP and SVG Files

Hi. I have created some .svg images from JFreeChart and want to embed them in a PDF document using FOP. Try as I might, using the External Graphic Inline Graphic route I cannot get it to display. Has anyone out there taken an existing svg file and embedded it successfully using FOP.

Many thanks in anticipation

Date, Calendar and TimeZones

Paul

Many thanks for that. I was confusing myself by putting the Date to System.out.println to check what it was being set to, which of course will use the toString - whoops.

Everything seems a lot better now.

Date, Calendar and TimeZones

Hi

I have a method where I am passing in a string and getting a Date object back. Because of DST or TimeZones I am getting odd results. I pass in 30/06/2006 23:30:00 and use SimpleDateFormat to parse it (using TimeZone.getTimeZone("GMT") as the timezone), and the date that I get out is Sat Jul 01 00:30:00 BST 2006.

Is there a way to get back a date object that is exactly equal to the string that I pass in without any DST alterations.

Thanks in anticipation

XSLT differences Java 1.4.2 to Java 1.6 ?

Just to follow up, got rid of the Sort and used this for the select

select="$nodes[not($nodes > .)]"

Works a treat.

...and that got posted before I could say.

Can anyone suggest what differences may have caused this.

XSLT differences Java 1.4.2 to Java 1.6 ?

Hi

I have an XSLT report that runs fine in Java 1.4.2 Windows XP, but I recently packaged the app and put it on a Vista machine with Java 1.6 on it, and a strange thing happened. Most of it worked, but one calculated data column in the report stopped working - no errors, no exceptions, just a blank column.

The XSL template that creates the value is this:
<xsl:template name="getHighest">
<xsl:param name="nodes" select="/.." />

<xsl:choose>
<xsl:when test="not($nodes)">0</xsl:when>
<xsl:otherwise>
<xsl:for-each select="$nodes">
<xsl:sort data-type="number" order="descending" />
<xsl:if test="position() = 1">
<xsl:value-of select="format-number(number(.),'#,###.##')" />
</xsl:if>
</xsl:for-each>
</xsl:otherwise>
</xsl:choose>

</xsl:template>

JInternalFrame Icons

Thanks for the reply - but I found a solution. I made the image 16 by 16 and it now works fine. This confused me as the bigger image 48 by 48 was OK in the JFrame, but the JInternalFrame - but there you go

JInternalFrame Icons

Hi

I am using a JInternalFrame with a Windows look and feel - when I set the icon with setFrameIcon it does not seem to draw it properly, and only partially shows the image. It is fine on the main JFrame however.

I have also tried:

UIManager.put("InternalFrame.icon", new javax.swing.ImageIcon(<my image path>

;

Has anyone got any ideas where I am going wrong ?

Thanks in anticipation
