To substitute the placeholders in the template with the actual values of the data returned from the

service call, use the eval() method of the Template object shown in the following example. This

method matches placeholders in the template file with fields of the same name in the results data

and replaces them accordingly. A check for valid results (output object) is done as shown in in the

following example. If there is no output object, an error template page is returned.

path = Application("templatedir")

If (Not IsObject(output)) Or (output is Nothing) Then

Call template.evalFile(path & "\nosession.temp", Null)

Elseif output.noError() Then

Call template.eval(iodata)

Elseif output.applicationError() Then

Call template.evalFile(path & "\error.temp", iodata)

Else

'// System error

Dim errdata(0)

Set errdata(0) = Server.CreateObject("BEAWEB.TemplateData")

Call errdata(0).setValue("ERRNO", output.getError())

Call errdata(0).setValue("ERRMSG", output.getStringError())

Call template.evalFile(path & "\syserror.temp", errdata)

End If

Note

The array iodata contains both the input request and the results from the service call. This is

useful if you want the results page to contain data that is part of the input.

When the template is processed, the resulting HTML is returned to the client as shown in

Figure 9-4.
