Im having a play with WebServices using IBM RAD 6 as my IDE.

I can get webservices to work ok when the message is a wrapper
containing Strings, ints, and arrays of Strings or ints, but as soon
as I try to use an array of complex types it fails.

The way it fails is that it says the array is an array of
'xsd:anyType' whereas I would expect something like 'impl:mytype'
where mytype would then have 'complexType' entry which would explain
that its just a String and an Int (for example)

Can anyone tell me how I should structure a message object to contain
arrays of wrapper classes? - or any neat tricks to avoid needing
arrays of wrapper classes.

Many Thanks

Heres the service....

public class HelloWorld8 {
public String helloWorld(HelloWorld8Msg aMsg) {

int arraySize = aMsg.getMyArray().length;
System.out.println("arraySize=[" + arraySize + "]");
String arrayContent = "";
for (int n = 0; n < arraySize; n++) {
arrayContent = arrayContent + ", " + aMsg.getMyArray()[n];
System.out.println("arrayContent=[" + arrayContent + "]");
}
return "Hello " + aMsg.getName() + "." + arrayContent + ".";
}
}


Heres the message...

public class HelloWorld8Msg extends AbstractHelloWorld8Msg {
public String name = "aa";

public HelloWorld8Msg() {
name = "bb";
}

public HelloWorld8Msg(String anName, HelloItem[] anMyArray) {
name = anName;
setMyArray(anMyArray);
}
/**
* @return Returns the name.
*/
public String getName() {
return name;
}
/**
* @param anName The name to set.
*/
public void setName(String anName) {
name = anName;
}
}

Heres HelloItem...

public class HelloItem implements Serializable {

public String key;
public String value;


public HelloItem(String anKey, String anValue) {
key = anKey;
value = anValue;
}
public String getKey() {
return key;
}
public void setKey(String anKey) {
key = anKey;
}
public String getValue() {
return value;
}
public void setValue(String anValue) {
value = anValue;
}

public String toString() {
return "key=[" + key + "], value=[" + value + "]";
}
}


Heres the super class...
import java.io.Serializable;

public class AbstractHelloWorld8Msg implements Serializable {
public HelloItem[] myArray = {new HelloItem("aaa", "Fred"), new
HelloItem("bbb", "Wilma"), new HelloItem("ccc", "Pebbles")};

/**
* @return Returns the myArray.
*/
public HelloItem getMyArray(int i) {
return myArray[i];
}
public HelloItem[] getMyArray() {
return myArray;
}
/**
* @param anMyArray The myArray to set.
*/
public void setMyArray(HelloItem[] anMyArray) {
myArray = anMyArray;
}
public void setMyArray(int i, HelloItem aHelloItem) {
myArray[i] = aHelloItem;
}
}
