Read/convert an InputStream to a String If you have java.io.InputStream object, how should you process that object and produce a String? Suppose I have an InputStream that contains text data, and I want to convert this to a String (for example, so I can write the contents of the stream to a log file). What is the easiest way to take the InputStream and convert it to a String? public String convertStreamToString(InputStream is) { // ??? } Answer: A nice way to do this is using Apache commons IOUtils to copy the InputStream into a StringWriter... something like StringWriter
