Title: RE: [jdjlist] Determine type from text

Jeff,

I am not sure if your question is regarding whether or not an object can be represented using XML or if you are trying to find out the types of the parameters of a method.

I will assume the second. If I am wrong, so sorry:)

Since you have already looked at reflection, did you try the java.lang.reflect.Method.getParameterTypes()? This returns an array containing one class object for each of the method's parameters.

Given the following xml file:

<?xml version="1.0"?>
<ServiceRequest>
   <Service>
      com.emerywaterhouse.websvc.FrtCalc
   </Service>
   <Method>
      getFreightCharge
   </Method>
   <Param>
      <Type>
        String
      </Type>
      <Value>
         UPSG
      </Value>
   </Param>
   <Param>
      <Type>
         String
      </Type>
      <Value>
         04104
      </Value>
   </Param>
   <Param>
     <Type>
         int
      </Type>
      <Value>
         100
      </Value>
   </Param>
</ServiceRequest>

Using reflection I can create the class, and call the method.  The only problem is determining and converting the parameters to the correct type.  I suppose I can use a brute force method and have a large number of if else statements, but that doesn't seem viable.  Also, if the parameter is an object, I'll never be able to code for all possible objects.

I've looked through a number of resources, but nothing I've seen has examples of determining the types for parameters.

Does anyone have a suggestion here or a resource I can look at.

TIA

Jeff
