Problem with indexOf ()
Hi, I have a strange problem with this method.
I have a some String like this:
":8547:Yog.Mora 200g:5123:0.4:0.5:123456789"
":8548:Yog.Mora 220g:5123:0.8:0.9:123456789"
":8549:Yog.Mora 250g:5123:1.0:1.2:123456789"
ok now I use indexOf to find when other Strings like this ones has a certaing substring on it. for example the substring "Yog." and works, but the problem is:
Searching for: "8547" works perfectly.
Searching for: "547" doesnt works.
how can this be posible if it finds 8547 it should find 547 but it doesnt, any clue?
how can this be posible if it finds 8547 it should find 547 but it doesnt, any clue? Your code is wrong, maybe you aren't searching from the start of the String. Anyway, we are wasting time guessing.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.

Problems with indexOf reading from an updating string
String[][] shapeArray = new String[5][2];
int isCol;
int isCom;
String outputsub1 = finoutput; // finoutput is holding text imported from a file
String outputsub2;
for (int y = 0; y < 2; y++)
for (int x = 0; x < 5; x++)
isCol = outputsub1.indexOf(":");
isCom = outputsub1.indexOf(",");
if (x == 4 && y == 1)
shapeArray[x][y] = outputsub1.substring((isCol+2));
else
shapeArray[x][y] = outputsub1.substring((isCol+2),isCom);
outputsub2 = outputsub1.substring(isCom+2);
outputsub1 = (outputsub2);
}the text imported looks like this...
Shape: Circle, Position: 100, 250, Size: 130, 130, Colour: Blue, Fill: yes
Shape: Rectangle, Position: 300, 250, Size: 110, 110, Colour: Red, Fill: no
i would use a string tokeniser, but i need to use this method. im trying to shorten the string each time so that the indexOf will find the next ":" each time. However when i try and update the string holding the updated data (outputsub1) i get the following error:
java.lang.StringindexOutOfBoundsException: String index out of range: -8
at java.lang.String.substring(String.java:144)
at ReadFile.init(ReadFile.java:52)
at sun.applet.AppletPanel.run(AppletPanel.java:353)
at java.lang.Thread.run(Thread.java:534)
i hope that makes sense to someone, it only occurs when i add the line..
outputsub1 = (outputsub2);
and works fine when i comment it out (although doesnt give the right response obviously.)
thankyou for any help you can offerString index out of range: -8 simply means that you try to access the String at position "-8", which obviously makes no sense. There must be some mistake either in your code or your algorithm. Keep in mind that indexOf returns -1 in case the argument wasn't found - maybe that's the reason for that error.

Help with add file name problem with Photoshop CS4
Frustrating problem: Help with add file name problem with Photoshop CS4. What happens is this. When I am in PS CS4 or CS3 and run the following script it runs fine. When I am in Bridge and go to tools/photoshop/batch and run the same script it runs until it wants interaction with preference.rulerunits. How do I get it to quit doing this so I can run in batch mode? Any help is appreciated. HLower

Problems with the Proxy Programme--Please help
Hi All,
I have written a simple proxy server in the form of a servlet. I changed the proxy config of my browser to connect to this servlet hosted on the default context(http://localhost:8080) of the Tomcat 5.0.25 . Well , this servlet internally connects to the proxy of the corporate LAN . The logic that I have applied is as follows. The servlet gets the request from the client (ie the browser in this case) , extracts the headers and contents from the request, sets them to a new request that it forms and finally send this new request to the proxy. When the proxy responds, the servlet collects the response headers and contents adn writes them in its response. To sum up , this servlet transparently carries the requests and responses between the client(browser) and the corporate LAN proxy. Now the problem is this. Let's say , now I am accessing http://www.google.com.The browser sends a request to my servlet with the following headers as they are extracted by my servlet.
ProxyServer:::>posting request
ProxyServer:::>headerValue::> headerName = accept : headerValue=*/*
ProxyServer:::>headerValue::> headerName = referer : headerValue=http://www.google.com/
ProxyServer:::>headerValue::> headerName = accept-language : headerValue=en-us
ProxyServer:::>headerValue::> headerName = proxy-connection : headerValue=Keep-Alive
ProxyServer:::>headerValue::> headerName = user-agent : headerValue=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; UB1.4_IE6.0_SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)
ProxyServer:::>headerValue::> headerName = host : headerValue=www.google.com
ProxyServer:::>headerValue::> headerName = cookie : headerValue=PREF=ID=1be27c0a74f198ca:TM=1082058853:LM=1082058853:S=bu6ORrygzm8AUkm8
ProxyServer:::>postRequest
I set these headers into a new connection opened to the proxy and post a fresh request to the proxy,which, in turn responds with the following headers.
ProxyServer:::>posted request successfully
ProxyServer:::>writing response
ProxyServer:::>writeResponse-->headerName = Proxy-Connection : headerValue = [close]
ProxyServer:::>writeResponse-->headerName = Content-Length : headerValue = [257]
ProxyServer:::>writeResponse-->headerName = Date : headerValue = [Tue, 13 Jul 2004 14:01:40 GMT]
ProxyServer:::>writeResponse-->headerName = Content-Type : headerValue = [text/html]
ProxyServer:::>writeResponse-->headerName = Server : headerValue = [NetCache appliance (NetApp/5.5R2)]
ProxyServer:::>writeResponse-->headerName = Proxy-Authenticate : headerValue = [Basic realm="Charlotte - napxyclt2"]
ProxyServer:::>writeResponse-->headerName = null : headerValue = [HTTP/1.1 407 Proxy Authentication Required]
ProxyServer:::>writeResponse exiting
ProxyServer:::>wrote response successfully
I write these headers back to the client. According to what I was thinking, the client ie the browser would open a new dialog box asking for username/password owing to the presence of the "Proxy-Authenticate " header. But it does not happen that way. Rather the browser stops responsding and displays a blank page. Does anyone know why it happens this way? I am pasting the server prog below for everybody's reference.

After being created, and before being connected, various options can be specified

Thanks for your reply. Well , I initially I thought of not pasting the code,as it was too long. But I could not help it,as I thought I must show in code what I exactly meant. That's why I followed a description of my problem with the code. You could probably have copied the code and pasted it in one of your favourite editors to take a look at it. Did you,by any chance, try to read it on the browser? And as regards reposting the same message, I can say that I did it as I felt the subject was not quite appropriate in the first posting and I was not sure as to how I could delete/alter the posting. I am not asking for a code-fix,but some suggestions from some one who might ever have come across such a thing.Anyway, lemme know if you have any idea on it. Thanks... -
Problem with Listeners/ requestFocus()
Hello,
I am new to Java (started learning two months back), There is a problem with the requestFocus() in the focusListener. The program does not return the focus to the object indicated in the requestFocus but it shows multiple cusors!!
The faculity at the institute where I am learning could not rectify the error.
Is the error because of the myMethod() which I am using. I had made this method to prove to my professor that we can reduce the code drastically while using the gridbaglayout.

// end of code.Would it not be acceptable to check that each field has a value when Submit is pressed. If a field is found with no data then display the error message and return the focus to the empty field. This would solve the multiple cursors problem as you would not need any focusLost handler code.
If this is entirely out of the question then you will have to override some of the FocusManager methods to prevent the JVM from handling focus for you :
FocusManager.setCurrentManager(new DefaultFocusManager() {
// Override FocusManager methods here.

I see that you have two opening <body> tags. Delete one; it is not needed. Add the preload images from the second into the first body tag and delete the second.
I see code below the closing </html> tag. Re position it before the closing </body> tag.
Because of these errors mentioned above, it was impossible to see the page. Fix and reply here when you have done so.

Problems with a thread that records dvd on suse linux
PLEASE HELP
I am using SuSE linux, and I record dvd+/- RW with the program growisofs.
By command line on the linux shell, growisofs records normally, but when I try to use the same line cone that I use in the shell in a java thread, it never stops recording, I mean, it records all data, but it apparently does not close the dvd session, for the grenn light on the drive never stops blinking, and I have to stop the proccess manually, because it never releases the dvd drive.
I use the thread in a large program, but for debugging this I have made a simple program, whose error is the same.
the code is:
String s = "/usr/local/bin/growisofs -speed=1 -M /dev/dvdram -V MIS27 -A growisofs -P MedImServer " +
" -p MedImServer -sysid Linux -J -R -l -relaxed-filenames -allow-lowercase -allow-multidot /windows/C/online";
Process p;
try {
p = Runtime.getRuntime().exec(s);
p.waitFor();
catch (IOException ex) {
JOptionPane.showMessageDialog(null,"erro no runtime");
System.exit(0);
catch (InterruptedException ex1) {
JOptionPane.showMessageDialog(null,"erro no waitfor");
System.exit(0);
}with JBuilder 9 debug, I realized that it freezes at the moment of "p.waitFor()".
I thought that it was a problem with the recording software, but it is not: the same command line that I use in the program I have used in the Linux shell and it recorded perfectly. The program does not require any user interaction but the command line I wrote before. The problem with the Java program is that it records all data, but never returns from the process. It's not a problem with the software, for it records perfectly when it's not called within the Java program, so I imagine that it is some funny thing in either the Runtime.getRuntime().exec(...) or the p.wait().
Better yet:
Is there a way to record dvds with a java command instead with an exteranal program?
This would be the heaven...
IF it is possible, do it require some sun package?

I tried to execute it, and it indeed doesn't freeze, but it doesn't record a thing either...
now it doesn't even wait for the thread, which is VERY weird: it does not record a thing!!! It just passes by the line 'p.waitFor()'...
Any sugestion?
By the way, thanks for helping me...

Hi everyone!!
The situation is this: I have a datable with one of its columns make an h:commanLink, which has two f:params, its actionListener is a function of a ManagedBean. This is JSF, not MyFaces. In IE, When the link is pressed, it shows a javascript error: " 'elements.idVar' is null or it's not an object ", however in Firefox, it works perfectly. I have been looking for the problem and it have to do with this:
</form><a href="# onclick="clearFormHiddenParams_formResultado('formResultado');document.forms['formResultado'['formResultado:_idcl'].value='formResultado:dtTablaResultados:0:_id10';document.forms['formResultado']['idVar'].value='37';document.forms['formResultado']['idMun'].value='168'; document.forms['formResultado'].submit(); return false;"><span id="formResultado:dtTablaResultados:0:itColumna3" title="AREA COSECHADA EN CULTIVOS PERMANENTES">1,230</span></a></td>
</tr>
<tr class="standardTable_Row2">
<td><span id="formResultado:dtTablaResultados:1:itColumna1" style="text-align:center;" title="Código Municipio">718</span></td>
<td><a href="javascript:void(0)" onclick="javascript:window.opener.opener.showLink('SASAIMA')"><span id="formResultado:dtTablaResultados:1:itColumna2_l" title="Municipio">SASAIMA</span></a></td>
<td><form id="formResultado:dtTablaResultados:1:_id9" method="post" action="/ConsultaEstadisticasGeo/resultadoConsulta.jsf" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="com.sun.faces.VIEW" id="com.sun.faces.VIEW" value="_id39:_id41" /><input type="hidden" name="formResultado:dtTablaResultados:1:_id9" value="formResultado:dtTablaResultados:1:_id9" /><input type="hidden" name="idVar" /><input type="hidden" name="idMun" /><input type="hidden" name="formResultado:_idcl" />
<script type="text/javascript">
<!--
function clearFormHiddenParams_formResultado_dtTablaResultados_1__id9(curFormName) {
var curForm = document.forms[curFormName];
curForm.elements['idVar'].value = null;
curForm.elements['idMun'].value = null;
curForm.elements['formResultado:_idcl'].value = null;
//-->
</script>
the way JSF manage the params. The error, acdording to the message shonw by IE is in this line: curForm.elements['idVar'].value = null;
The code of the JSP is this:
<h:commandLink actionListener="#{consultaEstadisticasMB.detalleEstadistica}">
<f:param name="idVar" value="#{consultaEstadisticasMB.idColumna3}" id="idVar" />
<f:param name="idMun" value="#{registro[0]}" id="idMun" />
<h:outputText title="#{consultaEstadisticasMB.columna3}" id="itColumna3" value="#{registro[2]}" />
</h:commandLink>
Waht can i do? (Not using MyFaces, because I can�t do that)
Thanks for your answers!!I have run into this same problem with javascript and the colon. I am not sure if the colon is a valid character for a javascript identifier (one would think the RI developers would have checked it out though!?!).
Anyway, my workaround is to search through the Javascript DOM for the widget you want to obtain a reference to, using part of its id. After all, you know its id, you just can't use it as a javascript reference. In your Javascript code, do something like:
var inputWidgets = document.getElementsByTagName("input");
var targetInput;
for(var i = 0; i < inputWidgets.length; i++)
var inputId = inputWidgets.id;
if(inputId.indexOf("yourInputId") != -1)
targetInput = inputWidgets[i];
break;
It's a lot of effort to just get a reference to a form widget....but it works (I pasted in the code and changed it a bit, so it might not work as is, but at least it demonstrates the idea). -
Strange Problem with a Vector wraped inside a Hashtable
Hi all ,
I'm having a strange problem with a Vector wraped within a Hashtable inherited Class.
My goal is to keep the order of the elements of the Hashtable so what I did was to extend Hashtable and wrap a Vector Inside of it.
Here is what it looks like :
package somepackage.util;
import java.util.Enumeration;
import java.util.Hashtable;
import java.util.Vector;
public class OrderedHashTable extends Hashtable {
private Vector index;
/** Creates a new instance of OrderedHashTable */
public OrderedHashTable() {
this.index = new Vector();
//adds a key pair value to the HashTable and adds the key at the end of the index Vector
public synchronized Object put(Object key,Object value){
index.addElement(key);
Object obj = super.put(key,value);
System.out.println("inside OrderedHashTable Put method index size = " + index.size());
return obj;
public synchronized Object remove(Object key){
int indx = index.indexOf(key);
index.removeElementAt(indx);
Object obj = super.remove(key);
return obj;
public synchronized Enumeration getOrderedEnumeration(){
return index.elements();
public synchronized Object getByIndex(int indexValue){
Object obj1 = index.elementAt(indexValue);
Object obj2 = super.get(obj1);
return obj2;
public synchronized int indexOf(Object key){
return index.indexOf(key);
public synchronized int getIndexSize() {
return index.size();
}Everything seemed to work fine util I tried to add objects using a "for" loop such as this one :
private synchronized void testOrderedHashTable(){
OrderedHashTable test = new OrderedHashTable();
for (int i = 1 ; i<15; i++){
System.out.println("adding Object No " + i);
String s = new String("string number = "+i);
test.put(new Integer(i),s);
System.out.println("-----------------------------------");
//try to list the objects
Enumeration e = test.getOrderedEnumeration();
while (e.hasMoreElements()){
Integer intObj = (Integer) e.nextElement();
System.out.println("nextObject Number = "+ intObj);
}Here is the console output :
Generic/JSR179: adding Object No 1
Generic/JSR179: inside OrderedHashTable Put method index size = 1
Generic/JSR179: -----------------------------------
Generic/JSR179: adding Object No 2

Generic/JSR179: nextObject Number = 8
Generic/JSR179: nextObject Number = 9
Generic/JSR179: nextObject Number = 9
Generic/JSR179: nextObject Number = 10
Generic/JSR179: nextObject Number = 11
Generic/JSR179: nextObject Number = 12
Generic/JSR179: nextObject Number = 13
Generic/JSR179: nextObject Number = 14
You can notice that the output seems correct until the insertion of object 9.
At this point the vector size should be 9 and the output says it is 10 elements long ...
In the final check you can notice the 9 was inserted twice ...
I think the problem has something to do with the automatic resizing of the vector but I'm not really sure. Mybe the resizing is done in a separate thread and the new insertion occurs before the vector is resized ... this is my best guess ...
I also tested this in a pure J2SE evironment and I don't have the same strange behavior
Can anybody tell me what I am doing wrong or how I could avoid this problem ?
Thanks a lot !
Cheers AlexAm i doing anything wrong?Uhm, yes. Read the API doc for addElement() and for addAll()

Problems with loading Classes from a Directory of a jar file.
Hi Guys,
i have a problem with my programm. It works greatly in my eclipse platform. but there are all classes in my default folder. I want to add a plugin function now. My Abstract classes are in in my default folder and my doughter classes are in my plugin-folder called plugin.
I look what is in the pluginfolder -> all my doughter classes. but i every time get a Class Cast Exception and an ClassNotFoundException.
How can i do that ? Current i do it with Class.forName(frames.substring(0,frames[i].indexOf(".class")));
best regards flohttp://java.sun.com/j2se/1.3/docs/tooldocs/win32/classpath.html

Problems with JApplet, jar-Archive, packages and IE5
Hello!
I have a problem with a JApplet and Internet Explorer 5. I made a jar archive of my classes. The classes are
members of a package. The jar archive also contains images.
The structure of the archive:
com/mycomp/myapp/DemoApplication.class
com/mycomp/myapp/DemoApplet.class
<more classes>
com/mycomp/myapp/images/hp_logo.gif
com/mycomp/myapp/images/test.gif
<more images>
The archive is stored locally in a directory which contains also the html file.
I used the sdk 1.3.1 to compile the classes.
My problem: when I start the html file on NT with IE5, I get the error message below:
I try to create a label containing an icon with:
topLabel.setIcon(new javax.swing.ImageIcon(getClass().getResource("images"+fs+"hp_logo.gif")));It works on Sun with Netscape 4.67 and SDK 1.3.1 installed.
Should I move the images directory inside the jar archive to another place or is the html code not correct?
The error message:

Problem with xmllistcollection
Hi
I am new in Flex programming world. I am facing the problem with xmllistcollection which is bind to datagrid. Please help me
I have created the custom componet. In this custom datagrid component a column having combobox. the problem aries when there
are two duplicate rows and if i change the value of one row's combobox value then another duplicate row's combobox value is autometically
changed.
as i have attached the images.image 1 shows initial stage and image2 shows when i changed 5 row's combobox value then 8th rows combobox
value is autometically changed.
this is the code for change of combox value. commented code shows what i have tried right now
public function DropDownEvent(evt:ListEvent):void
var xmlvalues:XMLListCollection= DataGrid(_listData.owner).dataProvider as XMLListCollection;
//var xmlListval:XMLList= xmlvalues.source as XMLList;
// XMLNotifier.getInstance().unwatchXML(xmlListval,);
xmlvalues[_listData.rowIndex][_listData.dataField]=evt.target.selectedItem;
// var xml:XML=xmlvalues.getItemAt(_listData.rowIndex) as XML;
// var strval:String=xml.toString();
// var lval:int= strval.indexOf(_listData.dataField);
// var lvalLength:int=_listData.dataField.length+lval+1;
// var str1:String=strval.substr(0,lvalLength);
// var lval2:int=strval.indexOf("</",lvalLength);
// str1=str1+evt.target.selectedItem+" "+strval.substr(lval2);
// var xmlNew:XML=new XML(str1);
// xmlvalues.removeItemAt(_listData.rowIndex);
// xmlvalues.addItemAt(xmlNew,_listData.rowIndex);
//Alert.show(xmlvalues[_listData.rowIndex].toString());
// evt.target.data[_listData.dataField]=evt.target.selectedItem;the problem seems to be due to watchxml notification function, which every time call when i try to change in the xmllistcollection. there may be the solution unwatchxml. but how to use unwatchxml in my code and what will be the notification function to remove ?
please help ! -
Strange problem with connection to Integrator Server
Hi,
I have a strange problem with making a connection to my Integrator Server.
I have one workspace folder that I share between Integrator version 2.4 and 3.0 (I have several versions installed for testing purposes)
When I try to create a new Integrator Server Project in Integrator Designer I get this nice 'Connect to CloverETL Server' panel.
By default: the connection URL is http://localhost:8080/clover. So by default Integrator Designer wants to connect to my 2.4 Integrator Server.
When I change this to http://localhost:8301/clover by using the drop-down box and fill in my credentials everything is looking fine. I click Next.
The problem now is that every time I switch to the next or previous configuration windows the connection is reset to the default http://localhost:8080/clover.
So it seems like Integrator Designer resets the CloverETL Server URL each time I switch to a different configuration window by using NEXT or BACK.
The problem occurs in both versions of Integrator Designer.
Does anybody know that the problem is? Can I change the default URL to my 3.0 Integrator Server?
Greetings,

Edited by: Marco Snels (AortaBI)(NL) on 31-mei-2013 4:59I'm using iPlanet App server as well and experiencing similar problem. I load my SQL Server driver by Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"), then use DriverManager.getDriver() to obtain the Driver.
However, the Driver returned is not the SQLServerDriver as expected. The Driver returned is com.netscape.server.jdbc.Driver! And then when I do Driver.getConnection("jdbc:microsoft:sqlserver://MyServer"), it throws an SQLException saying that it doesn't accept a jdbc:microsoft:sqlserver subprotocol. Well, of course it doesn't, it's not a microsoft Driver at all.
I suspect the problem is that the netscape Driver's acceptsURL() method ALWAYS returns true in iPlanet app server, thus when you getDriver(), the netscape Driver is always returned (and always returned as the first one since it's default?). Thus even though the same piece of code works fine as a standalone application, it just doesn't work on iPlanet app server.
My work around is:
Class.forName("my.Driver");
Enumeration enu = DriverManager.getDrivers();
Driver useThis = null;
while (enu.hasMoreElements()) {
Driver d = (Driver)enu.nextElement();
if (d.getClass().toString().indexOf("my.Driver") > -1) {
useThis = d;
Mind that my above code does not have an performance issue. If you look into the source code of how DriverManager get a Driver for a particular URL, it also loads the whole set of available Drivers, then call acceptsURL() method on each of them to find the first "suitable" one. Thus time complexity is the same.
I know this is not a very elegant solution and it defeats the purpose of having a DriverManager. Does any one else has a better way to solve this problem, like a way to specify the priority of each Driver so that SQLServerDriver is returned before the netscape Driver?
Thanks a lot. -
Hi Experts,
I got one problem with IE9. Let see what the error occur.
1. Click on <Add Initiative>
2. Click on <Calendar Button on Start*> ([http://1.bp.blogspot.com/-cHhGF6VetRU/Ty9P7nviUsI/AAAAAAAAAAM/9orLRDopwSE/s1600/Untitled.jpg])
3. Get Error ([http://1.bp.blogspot.com/-SJn4azyfoXY/Ty9P9LiCYXI/AAAAAAAAAAU/UhUrL412vxo/s1600/Error.jpg])
Appreciate for your help.

Edit the file \usr\sap\SSD\J00\j2ee\cluster\apps\sap.com\xappscpmsm~strategymanagement\servlet_jsp\strategy\root\pilotworks\sccalendar2.htm
Insert this in the 30th line:
CurrentDate = new Date(CurrentDate)
And you get something like this:
if (self.location.href.indexOf("Type=Double1") != -1)
CurrentDate = parent.FromDate
else if (self.location.href.indexOf("Type=Double2") != -1)
CurrentDate = parent.ToDate
else
CurrentDate = parent.CurrentDate
CurrentDate = new Date(CurrentDate)
// get same date in the previous year
var PreviousYear = new Date(CurrentDate)
PreviousYear.setFullYear(PreviousYear.getFullYear() - 1)
if (PreviousYear.getDate() != CurrentDate.getDate())
PreviousYear.setDate(0)
Hope this helps. -
I am writing a mobile client that makes an HTTP Connection and performs a POST to the a Web Services Server. The WS is running .NET. My client works as it should running on all the emulators out there, however, I�m having a problem with an actual device. Then the InputStream is returned but the HTTPConnection.getLength returns >= 0. So I had to make a patch to read the InputStream in chunks and then discard the header section. This results in an �Unexpected End of Input Stream� Exception. Is this going to be a problem with other devices then the one I tested with: The Audiovox SMT-5600? I contacted the vendor but they won�t give any help on outside issues. The headers are getting mixed in with the stream returned. This does not happen on the emulator, the emulator filters out the headers and returns the length of the SOAP message. Here is the following code I have tried to correct this problem. If anyone has run into this issues and can give me some instruction on how to work around this problem I would appreciate it a lot. Thank you in advance!
int length = 0;
HttpConnection hc = null;
OutputStream out = null;
DataInputStream in = null;
hc = (HttpConnection)Connector.open(SOAP_SERIVCE_URL);
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
hc.setRequestProperty("Content-Length", Integer.toString(soapMessage.length()));
hc.setRequestProperty("SOAPAction","\"" + soapAction + "\"");
out = hc.openOutputStream();
out.write(soapMessage.getBytes());
in = hc.openDataInputStream();
length = (int)hc.getLength();
byte[] data = new byte[(int)length];
in.read(data);
This does not work because the length is not being returned. I have also tried this:
int length = 0;
HttpConnection hc = null;
OutputStream out = null;
DataInputStream in = null;
hc = (HttpConnection)Connector.open(SOAP_SERIVCE_URL);
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
hc.setRequestProperty("Content-Length", Integer.toString(soapMessage.length()));
hc.setRequestProperty("SOAPAction","\"" + soapAction + "\"");
out = hc.openOutputStream();
out.write(soapMessage.getBytes());
in = hc.openDataInputStream();
length = (int)hc.getLength();
if (length <= 0) {
String contentLength = hc.getRequestProperty("Content-Length");
length = Integer.parseInt(contentLength);
byte[] data = new byte[(int)length];
in.read(data);
This works but since the HTTP Headers are in the input stream and not filtered out I don't get the whole SOAP Message. I tried to read the input stream in chunks:
int length = 0;
HttpConnection hc = null;
OutputStream out = null;
DataInputStream in = null;
String response;
hc = (HttpConnection)Connector.open(SOAP_SERIVCE_URL);
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
hc.setRequestProperty("Content-Length", Integer.toString(soapMessage.length()));
hc.setRequestProperty("SOAPAction","\"" + soapAction + "\"");
out = hc.openOutputStream();
out.write(soapMessage.getBytes());
in = hc.openDataInputStream();
length = (int)hc.getLength();
if (length > 0) {
gs.setPositionStr("length > 0");
int actual = 0;
int bytesread = 0 ;
byte[] data = new byte[length];
in.readFully(data);
response = new String(data);
} else {
int chunkSize = 512;
int index = 0;
int readLength = 0;
byte[] data = new byte[chunkSize];
do {
if (data.length < index + chunkSize) {
byte[] newData = new byte[index + chunkSize];
System.arraycopy(data, 0, newData, 0, data.length);
data = newData;
readLength = in.read(data, index, chunkSize);
index += readLength;
} while (readLength == chunkSize);
length = index;
response = new String(data);
response = response.substring(response.indexOf("<?xml") -1); //remove the HTTP headers from the SOAP envelope
This methods gets into the else block because there is no length specified, but it throws an 'Unexpected End of Input Stream' exception. Looking at the response string only a portion of the input stream was read.Think simple! A query to the "Content-Length" won't work if the response is chunked (and it probably is). That's why getLength will return 0.
Solution is much simpler that sun does in the javadocs example codes:
int BUFFERSIZE=128;
ByteArrayOutputStream bout = new ByteArrayOutputStream();
byte[] buffer = new byte[BUFFERSIZE]
int bs = 0;
while((bs = in.read(buffer,0,buffer.length)!= -1){
bout.write(buffer,0,bs);
String response = bout.toString();It is always fast, simple, and short :) no if/else crap. Forget the length, and just read until end of stream and convert to String.
