Requirements are far from complete but the basic process is.
1. Learn how to call an external Web API in java
2. Code it to call one service
3. Wrap that in a class.
4. Depending on the exact APIs that you are calling you might be able to use the same class or copy and modify for each different external Web API
5. Use the above in your servlet.
I suggest STRONGLY that you consider error scenarios where the external servers fail to connect, or fail to respond. If you just assume they will work all of the time then when they do fail you will have no idea what is going on.

I wrote a test operation like this:
@WebMethod(operationName="setSomeInfo")
public String setSomeInfo(List<String> values){
String retval = "";
List<String> x = values;
if(x.size() > 3){
retval = x.get(3);
}
return retval;
}
and this works perfectly.
However, When I create an object like this:
public class MyWSObject {
private String mystring;
private List<String> mystringarr;
public void setMyString(String value){
mystring = value;
}
public void setMyStringArr(List<String> values){
mystringarr = values;
}
public String getMyString(){
return mystring;
}
public List<String> getMyStringArr(){
return mystringarr;
}
}
and I use it in an webmethod:
@WebMethod(operationName="setSomeInfo")
public String setSomeotherInfo(MyWSObject myobject){
String str_val = myobject.getMyString();
List<String> str_list = myobject.getMyStringArr();
}
I cannot consume it (completely). In the client the MyWSObject is recognized with the methods setMyString, getMyString and getMyStringArr, but not setMyStringArr.
I looked this up and it seems to be a known problem, but I find it hard to believe that something basic as an array or a list is so hard to define. I'm working with NetBeans/glassfish.
Is there a simple solution to this?
(Most solutions I found involved modifying the wsdl, setting compilation options or writing wrapping classes or a combination of those.)

You did try it with an array rather than the List?

i've tried this, How can i get it in proper way?
int sum=0;
String values = null;
while (rs.next()) {
values = rs.getString(1);
String[] valueTokens = values.split("\\s");
for(int i=0;i<valueTokens.length;i++){
System.out.print(valueTokens[i]);
System.out.print(",");
if( i % 6 == 0 ) {
System.out.println();
sum += i; }
}
}

Where does this data come from and why are you storing it as strings rather than numbers? You could use the string.format[^] or string.replace[^] method to build your comma separated string for output,

Data come from MySQL database
i stored them in String because i want all points in one record for single Shape, when i need to draw one shape i just retrieve that particular record,especially my shapes are based on cubic curves, which each shape needs 6 points to draw one curve (it should begin with starting point as starting point of the shape)

Hi, what I want to do is to capture live video from a webcam in this java application, but had an error when I run this set of code:
java.io.IOException: Could not connect to capture device
javax.media.NoDataSourceException: Error instantiating class: com.sun.media.protocol.vfw.DataSource : java.io.IOException: Could not connect to capture device
I had already put the jmf.jar into the lib folder.
<pre lang="java"> public class CamRecorder {
static VideoFormat videoFormat;
static AudioFormat audioFormat;
static CaptureDeviceInfo videoDevice;
static CaptureDeviceInfo audioDevice;
public static void main(String[] args) {

CaptureDeviceInfo device = (CaptureDeviceInfo) deviceList.firstElement(); //in this computer the only capture device is in=built webcam stays at 0th position
Format[] formats = device.getFormats(); //get all formats
for (int x = 0; x < formats.length; x++) {
if (formats[x] != null && formats[x] instanceof VideoFormat) {
videoFormat = (VideoFormat) formats[x]; //take the video format
videoDevice = device;
}
/*if (formats[x] != null && formats[x] instanceof AudioFormat) {

//audioDevice = device;

}
//create data sources

A five for the effort, but alas still can't import the project. I guess i'll move on to chapter 6 and hope I don't miss much.
Thanks anyway.

Import into what? Have you tried just creating a new project and using copy and paste to add the source code?
