SOAP - method return
Hi,
I am doing LDAP call using soap .I want to return Hashtable from my
method call.
On my client site I am using following code to get my hashtable.
Response resp = call.invoke(url, "");
Parameter p = resp.getReturnValue();
Hashtable values = (Hashtable)p.getValue();
I am getting following exception.
The SOAP Server says:
http://localhost:8080/soap/servlet/rpcrouterException in t
hread "main" java.lang.NullPointerException
at LDAP_client.main(LDAP_client.java:36)
any help will be useful.
Vijay

Scott,
Thanx for your help.
I solved my problem by making some changes in my method.
Now i am creating a dummy Hashtable and populating them with the result of
the Enumaration so i can just get a plain Hashtable in my method return
type.
In future i may need to return a java object.Thanx a lot for your timly
help.
Thanx & Regards,
Vijay

Re: SOAP - method return
Posted by Scott Nichol <sn...@scottnichol.com>.
The Hashtable mapping is implicit: you do not need it in your
deploymentdescriptor.
As you can see, the error is actually finding a serializer for
java.util.Vector$1. This class exists back to JDK 1.2; it is an
anonymous class implementing the Enumeration interface defined by the
Vector#elements() method. I take it that the elements in your Hashtable
are such Enumerations.
What you need to do is write a serializer and deserializer for such
Enumerations and map them to java.util.Vector$1 (map the serializer on
the server and the deserializer on the client).
Alternatively, if you can rewrite the method (or add a new method) to
return a Hashable of Vectors instead, the built-in Vector serializer
will do the work for you.

Scott,
Here are the details.
I guess i need to provide the mapping in my DeploymentDescriptor.xml.
Here is my descriptor.

</dd:mappings>
</dd:service>
I am returning Hashtable from my method call.
I am getting following exception.
The SOAP Server says: http://localhost:8080/soap/servlet/rpcrouter
Ouch, the call failed:
Fault Code = SOAP-ENV:Server
Fault String = java.lang.IllegalArgumentException: No Serializer found to
seri
alize a 'java.util.Vector$1' using encoding style
'http://schemas.xmlsoap.org/so

I have provide mapping for hashtable why it is throwing me error for vector
class?.
are my mappings correct?

Re: SOAP - method return
Posted by Scott Nichol <sn...@scottnichol.com>.
A couple of things:
1. Which line of your code is line 36 where the exception is occurring?
2. Your code should check for a SOAP Fault before doing
getReturnValue(), e.g.
Response resp = call.invoke(url, "");
if (resp.generatedFault()) {
Fault fault = resp.getFault();
System.err.println("Generated fault: " + fault);
} else {
Parameter p = resp.getReturnValue();
Hashtable values = (Hashtable)p.getValue();
...
If there is a fault, I believe that getReturnValue() will return null,
so calling it without checking for a fault could lead to an NPE.
3. Although I take it you are using Apache SOAP on the server in this
case, it is worth pointing out that some SOAP implementations will omit
the return value from the SOAP envelope if its value is null (e.g. this
happens in .NET when the return is not specified as being nillable).
Therefore, it is good practice in your client code to check that
getReturnValue() does not itself return null.
