inputs allows for user-supplied params at runtime.  variables are for temporary storage.

hi raj

Thanks for your inputs
i am just wondering if we can use input and variables interchangebly

e.g.

in assign statement

    <variable name="myString" type="string"/>
   
   <assign fromexpr="$fastserxml/SearchResponse" outputvariable="myString" />
   

now should fastserxml be declared as a variable or is it ok if its declared as input type

They can be used interchangeably in the example you gave. The primary differences between <input> and <variable> are that <input> is exposed as a parameter that can be passed at runtime when a mashup or a macro is invoked.

 Is it safe to say that variables do not have to be named explicitedly? i.e., in a variables element.

You can implicitly declare variables in the outputvariable attributes of most statements. When you do this, Mashup Server creates a variable of that name with a document type -- so as long as that works for your situation -- yes.
