using Jython

To read the contents of a file into a String using a Jython script you can use the following method:

CODE

from java.lang import *
from java.io import *
from soaptest.api import *

def getContents(input, context):
  contents = StringBuffer()
  reader = BufferedReader(FileReader(File("c:\Documents and Settings\jhendrick\Desktop\test.txt")))
  line = String()
  while line != None:
    line = reader.readLine()
    if line != None:
      contents.append(line)
    contents.append(System.getProperty("line.separator"))
  reader.close()
  return contents.toString()

If you have trouble with the above script, then you will also want to visit the following forum post:

There, you will find a download and instructions. Please try this first.

Is it possible to use relative path, instead of absolute ?
I am using SOA 6.1, and it doesnt work for me.
reader = BufferedReader(FileReader(File("test.txt")))

  reader = BufferedReader(FileReader(File("c:\Documents and Settings\jhendrick\Desktop\test.txt")))
  line = String()
  while line != None:
    line = reader.readLine()
    if line != None:
      contents.append(line)
    contents.append(System.getProperty("line.separator"))
  reader.close()
  return contents.toString()[/code]

To get the absolute path of a file. Assuming that the file is in the same project folder. Following code can be used.

CODE

filePath = str(context.getAbsolutePathFile("test.txt"))
reader = BufferedReader(FileReader(File(filePath)))

SOAtest has since added utility methods so that you don't need to read a file line-by-line.

For an Extension Tool when you know the path to a file:

CODE

from com.parasoft.api import IOUtil
from java.io import File

def main(input, context):
    # Create java.io.File however you can.
    file = File("path/to/what/you/want")
    return IOUtil.readTextFile(file)

For a standalone Extension Tool when you have configured the Input tab to use a file as the input:

CODEfrom com.parasoft.api import IOUtil

def main(input, context):
    # input is of type java.io.File
    return IOUtil.readTextFile(input)

IOUtil.readTextFile returns a string. If you have a binary file, you can use IOUtil.readBinaryFile, which returns a byte array (byte[] in Java).
