Armin Aschoff updated NIFI-9944:
--------------------------------
Description:
Create a new InvokeScriptedProcessor.
Set Module Directory: ./scripts/jars/commons-text-1.6/
- have tried setting absolute & relative paths, paths to directories, paths to
jar files, different versions of commons-text, trailing slash/no trailing
slash, etc. No differences
Set script engine ECMAScript
Write js script that tries to call a static method in commons-text. Script can
be either script file or script body, no difference
Always get ClassNotFoundException error:
{noformat}
Component is invalid: 'ScriptValidation' validated against
'./scripts/testCsv.js' is invalid because Unable to load script due to
java.lang.ClassNotFoundException:
org.apache.commons.text.StringEscapeUtils{noformat}
Have tried Java.type and Packages. to try to access the class.
Any/all help much appreciated as rapidly losing remaining hair!
Sample script:
{code:java}
// base interface & class stuff
var Processor = Java.type("org.apache.nifi.processor.Processor")
var Relationship = Java.type("org.apache.nifi.processor.Relationship")
var HashSet = Java.type("java.util.HashSet")
var log = null
// stuff to read/write flowfile content
var InputStreamCallback =
Java.type("org.apache.nifi.processor.io.InputStreamCallback")
var OutputStreamCallback =
Java.type("org.apache.nifi.processor.io.OutputStreamCallback")
var IOUtils = Java.type("org.apache.commons.io.IOUtils")
var StandardCharsets = Java.type("java.nio.charset.StandardCharsets")
var StringEscapeUtils = Java.type("org.apache.commons.text.StringEscapeUtils")
function getPropertyDescriptors() { return []}
// =========== Define output relationships ================
var REL_SUCCESS = new
Relationship.Builder().name("success").description("FlowFiles that were
successfully processed are routed here").build()
function getRelationships() {
var r = new HashSet()
r.add(REL_SUCCESS)
return r
}
//=======================================
// Execute the main script when triggered
function onTrigger(context, sessionFactory) {
var session = sessionFactory.createSession()
var flowFile = session.get()
if (flowFile !== null) {
var test = "boo"
test = StringEscapeUtils.escapeCsv("foo")
log.warn(test)
session.transfer(flowFile, REL_SUCCESS)
}
session.commit()
}
// ======================================================
// Other functions required to satisfy interface contract
function initialize(context) {log = context.logger}
function validate(context) {return null}
function getPropertyDescriptor(name) {return
getPropertyDescriptors().find(function (property) {
return property.getName().equalsIgnoreCase(name)
})}
function onPropertyModified(descriptor, oldValue, newValue) {return null}
function getIdentifier() {return null}
processor = this
