Subject: Hashtable and Vector
Question
Hi,
I am new to
axis.
I did search the
mailing list but I was unable to find answers to 3 distinct problems that I
have to solve.
We have 3 diferent
java classes. They are:
public class
BooleanExample
{
public boolean business(String input)
{
boolean output = false;
... do something with output.
return output;
}
}
public class
HashtableExample
{
public Hashtable business(String
input)
{
Hashtable output = new
Hashtable()
... fill output with
data.
return output;
}
}
public class
VectorOfHashtablesExample
{
public Vector business(String
input)
{
Vector output = new
Vector();
Hashtable data = ""
Hashtable()
... fill
data
... add several data filled Hashtables to
output
return output;
}
}
I am looking to
expose these classes as a Web Service but I need to assure
interop.
The way I see it,
class one (BooleanExample) does not represent a problem.
The web service
deployment descriptor would be something like:
<service
name="BooleanExample" provider="java:RPC">
<parameter name="className"
value="BooleanExample"/>
<parameter
name="allowedMethods"
value="business"/>
</service>
I read
the following on the Axis manual:
"Java
Collections
Some of the Collection classes, such as Hashtable
do have serializers, but there is no formal interoperability with other SOAP
implementations, and nothing in the SOAP specifications which covers complex
objects. The most reliable way to send aggregate objects is to use arrays. In
particular, .NET cannot handle them, though many Java SOAP implementations can
marshall and unmarshall hash tables."
Supose I have the following
hashtable: {key 1=value 1, key 2=value 2}
To assure interop do I have
to convert this to two vectors? Like [key 1, key 2] for the keys, and
[value 1, value 2] for the values? Do I have to send then over the wire
one at a time?
Now for the Vector. Ok, I
could convert it to an Array using toArray, but I would still have an Array of
Hashtables. No good.
So the first question I have
is: can I use multidimensional String Arrays?
This way I would use the
above solution for each Hashtable on the Vector, and then, only then, I would
convert the Vector to an Array.
Any help is
welcome.
Thanks
John
