There has to be a simple answer for this that I haven't been able to
find. This is one of those difficult things to search for because all
the terms are very common.
I have a simple value object class that is being sent via a simple web
service call. Inside the class are some Integer variables that may
not be set when sent. So I can easily create a new VO class, and send
it from my client to the server.
The problem is that on the server I get a NumberFormatException
because it is trying to create an Integer from an empty string. The
exact error is:
java.lang.NumberFormatException: For input string: ""
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
...
Using tcpmon I see that the SOAP being sent is:
...
<soapInsertUser xmlns="http://dataimport.processes.ix/xsd";>
<arg0 xmlns="">
<firstname>hank</firstname>
<lastname>hank</lastname>
<assignedUserID
xmlns:nil="http://ww.w3.org/2001/XMLSchema-instance"; nil:nil="true" />
</arg0>
</soapInsertUser>
...
So my question is... why is it taking a null value, and trying to call
parseInt on an empty string? What I thought would have happened is
that it would correctly deserialize into a null value, or that it
wouldn't even send the null value in the SOAP call.
There has to be something simple that I am missing here. I am using
Axis 2 and can provide code if necessary. Please point me to any docs
that are applicable to this subject.
