SOAP Request using groovy

I created the following groovy program test.groovy to invoke BI Publisher web service. I am able to get the soap response. Can anyone please help me to write the soapresponse ( Envelope.Body.runReportResponse.runReportReturn.reportBytes ) to pdf file.

----------------------- test.groovy ------------------------------------

String username = "Administrator"
String password = "Administrator"
String attributeFormat = "pdf" 
String attributeLocale = "en-US"
String reportAbsolutePath = "/WebserviceTest/eodnoticeofdormancy/eodnoticeofdormancy.xdo"
String attributeTemplate = "Notice"
String p_reportdate = "2011-04-08"

def soapRequest = """<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:pub="http://xmlns.oracle.com/oxp/service/PublicReportService">

try {
   def soapUrl = new URL("http://localhost/xmlpserver/services/PublicReportService")
   def connection = soapUrl.openConnection()
   connection.setRequestMethod("POST")
   connection.setRequestProperty("Content-Type" ,"text/html")
   connection.setRequestProperty("SOAPAction", "")
   connection.doOutput = true

   Writer writer = new OutputStreamWriter(connection.outputStream)
   writer.write(soapRequest)
   writer.flush()
   writer.close()
   connection.connect()


   def soapResponse = connection.content.text
   def Envelope = new XmlSlurper().parseText(soapResponse)

   println soapResponse

   String reportBytes = Envelope.Body.runReportResponse.runReportReturn.reportBytes
   String reportContentType = Envelope.Body.runReportResponse.runReportReturn.reportContentType

} catch (Exception e) {
   println "Error occurred"
   println "--------------"

The String coming back is Base64 encoded, with some characters at the end that appear to be indicating the content-type ("application/pdf") and the original file name ("xmlp25327697.tmp"). If you strip off everything starting at "application" you can then decode the String to bytes and write it to a file like this:

byte[] decoded = reportBytes.decodeBase64()
def myFile = new File('something.pdf')
myFile.bytes = decoded
