Below is my Pgtyp.groovy (domain class):
package marchmock2
class Pgtyp {
Date date_hour
String mv
String pagetype
Integer visits
Integer visits_ly
Integer visits_lw
String time_period
String platform
String device
String browser
static mapping = {
table "pgtyp"
version false
date_hour column: "date_hour"
mv column: "mv"
pagetype column: "pagetype"
visits column: "visits"
visits_ly column:"visits_ly"
visits_lw column:"visits_lw"
time_period column:"time_period"
platform column:"platform"
device column:"device"
browser column:"browser"
}
static constraints = {
}
}
This is how my controller looks like:
package marchmock2
import grails.converters.*
import groovy.sql.Sql
class PgtypController {
def ajaxGetMv = {
def pgtyp = Pgtyp.get(params.id)
render pgtyp as JSON
}
def index() {
}
}
And finally, this is my index.gsp:
<html>
<head>
<g:javascript src="jquery-1.10.2.min.js"/>
<g:javascript src="prototype.js"/>
</head>
<body>
<form>
<g:select from="['AFFILIATES', 'SEO', 'SEM','DISPLAYADS']" name="mv" onchange="${remoteFunction(
controller:'Pgtyp',
action:'ajaxGetMv',
params:'\'id=\' + escape(this.value)',
onSuccess: 'printpgtyp(data)')}"></g:select>
</form>
<g:javascript>
function printpgtyp(data) {
console.log(data)
}
</g:javascript>
</body>
</html>
When I run my app, I get a dropdown and on selecting any option from it I get an error saying:
POST http://localhost:8080/marchmock2/pgtyp/ajaxGetMv 500 (Internal Server Error)
What do I do with it? Is there any error in the way I'm writing it or have I misunderstood anything? Any help would be appreciated.

I have created a service NotifierService to send emails using grails mail plugin.
class NotifierService {
MailService mailService
def sendWarningEmail(String name, String email, Date blockingDate) {
try {
mailService.sendMail {
to email
from "noreply-myApp#domain.com"
subject "Status message: Warning"
body (view:"/email/warningEmail", model:[
name:name,
blockingDate:blockingDate
])
}
} catch (Exception e) {
e.printStackTrace()
}
}
}
I have created another service ApplicationUtilService in which I am trying to use the NotifierService.
class ApplicationUtilService{
def notifierService
def notifyUser(){
notifierService.sendWarningEmail("User name", "user#domain.com", new Date())
}
}
I am trying to call notifyUser() in a grails job UpdateJob
class UpdateJob{
def applicationUtilService
static triggers = {
// Scehduling parameters
}
def execute(){
applicationUtilityService.notifyUser()
}
}
I get the following error
Error 2014-12-05 12:04:53,550 [quartzScheduler_Worker-1] ERROR listeners.ExceptionPrinterJobListener - Exception occurred in job: Grails Job

^ 573 | run . . in org.quartz.simpl.SimpleThreadPool$WorkerThread ...`
It works when I instantiate as
ApplicationUtilService applicationUtilService = new ApplicationUtilService()
instead of using grails dependency injection. Again, the same problem with the notifierService in ApplicationUtilService and fixed by instantiating same as above.
Now, the real problem is with the mailService. The instantiation as above didn't work. How could I resolve it
The Null Pointer is occurring on UpdateJob.applicationUtilService, so it seems like applicationUtilService isn't being injected into UpdateJob correctly. Is UpdateJob in the right package?
I get the error "Caused by NullPointerException: null ->> 64 | getMailConfig in grails.plugin.mail.MailService". I have configured the config.groovy as per the documentation provided by mail plugin.
Please help me to resolve this issue.
Find my config.groovy code below.
grails
{
mail {
host = "smtp.gmail.com"
port = 465
username = "xxxxxx#gmail.com"
password = "xxxxxx"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
Find my groovy class code below.
package common
import grails.plugin.mail.*;
public class FlowSchedule implements Job {
def mailService = new MailService()
public void execute(JobExecutionContext context)
throws JobExecutionException {
//some extra logic here
sendEmail(schedulerEntry.name,schedulerEntry.email)
}
def sendEmail(String name,String email)
{
mailService.sendMail {
to "amith.ravuru#citrix.com"
subject "Hello Amith"
body 'this is some text'
}
}
}

I solved the issue by moving the sendEmail part to a controller. Then, call the controller method from any class in src/groovy. Because, in controllers, grailsApplication can be injected using def grailsApplication. Please find the controller code below.
class SendMailController
{
def grailsApplication
def sendEmail(String name,String email,String mailsubject)
{
if(email != null)
{
try
{
sendMail {
to email
from "exabgpnotifier#gmail.com"
subject "ExaBGP Notification"
body "Hello "+name+"\n\n"+ mailsubject +" \n\nRegards,\nExaBGP Team"
}
}
catch(Exception e)
{
e.printStackTrace()
println "ERROR!!: Unable to send the notification to email "+ finalemaillist.toString()
}
}
}
}
I guess that this plugin injects mailService into your application. So instead of creating service with constructor like you've done:
def mailService = new MailService()
Just declare the field and let DI mechanism to do the work of injecting the value:
def mailService
The remaining part of your code looks okay. Think about changing the name of sendMail method, now it's a bit confusing when you've got the same names for your method and the one from mailService.
Hope it'll help!
I don't think this will work:
grails
{
mail {
host = "smtp.gmail.com"
port = 465
username = "xxxxxx#gmail.com"
password = "xxxxxx"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
That is valid code but doesn't do what you intend. The opening curly brace after grails needs to be on the same line so the closure is treated as an argument to the grails method.
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "xxxxxx#gmail.com"
password = "xxxxxx"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
Open you resources.groovy file and put this entry.
import common.FlowSchedule
beans = {
// make sure you import flow schedule class
flowSchedule(FlowSchedule) {
mailService = ref('mailService')
}
}
Then in your class.
package common
import grails.plugin.mail.*;
public class FlowSchedule implements Job {
def mailService
public void execute(JobExecutionContext context)
throws JobExecutionException {
//some extra logic here
sendEmail(schedulerEntry.name,schedulerEntry.email)
}
def sendEmail(String name,String email)
{
mailService.sendMail {
to "amith.ravuru#citrix.com"
subject "Hello Amith"
body 'this is some text'
}
}
}
When you need flow schedule in any controller or service then just do this
class MyService {
def flowSchedule
def myMethod() {
flowSchedule.sendEmail('test','test#test.com')
}
}
using the spring security core plugin I am trying to catch event so I am using
grails.plugin.springsecurity.useSecurityEventListener = true
grails.plugin.springsecurity.onInteractiveAuthenticationSuccessEvent = { e, appCtx ->
def request = org.codehaus.groovy.grails.plugins.springsecurity.SecurityRequestHolder.getRequest()
def session = request.getSession(false)
session.myvar=2
}
but it give me :

notice that the line 158 in the config file is exactly the line
def request = org.codehaus.groovy.grails.plugins.springsecurity.SecurityRequestHolder.getRequest()
which is crazy because I am not invoking groovy.util.ConfigObject.getRequest() in this line
I already tried to clean and compile but nothing change.
and at the same time if I want to catch the failure login event, what event I must catch?
update
I am using grails 2.3.8 and spring-security-core:2.0-RC2
To answer the question
This may be late but...
I believe you mean
def request = grails.plugin.springsecurity.web.SecurityRequestHolder.getRequest()
(note the different package name)
This may not be of much help to #Bilel but it may be to anyone else who happens upon the question.
One a side note:
which is crazy because I am not invoking groovy.util.ConfigObject.getRequest() in this line
When you see weird things like groovy.util.ConfigObject I have come to notice that it usually means a variable in Config does not exist.
Also, on another note:
I don't know if doing it in Config.groovy is an absolute requirement but I believe this gets cleaner if you register a listener.
Here's what I would do:
import org.springframework.context.ApplicationListener
import org.springframework.security.authentication.event. InteractiveAuthenticationSuccessEvent
class MyLoginListener implements ApplicationListener<InteractiveAuthenticationSuccessEvent> {
void onApplicationEvent(InteractiveAuthenticationSuccessEvent event) {
def request = grails.plugin.springsecurity.web.SecurityRequestHolder.getRequest()
def session = request.getSession(false)
session.myvar=2
}
}
and then register it in resources.groovy
beans = {
myLoginListener(MyLoginListener)
}
You need the following line in Config.groovy, but you may already have it there anyway.
grails.plugin.springsecurity.useSecurityEventListener = true
A confused Grails newbie here. I am currently going through the tutorials in
a book (Smith, Ledbrook, "Grails in Action", Manning Publications, 1st Ed)
and am stumped in the first chapter! When browsing to localhost, I get the
error messages further below. The tutorial leads me through creating a
Random Quote of the Day application. As you might suspect, browsing to the
webpage gives a random quote (which were saved in the "Quote" domain class)
with each refresh.
I have made the controller, view, layout, domain class, all of which are
pretty simple. I would imagine that I'd get these errors if there were no
test data, but using the grails console shows me that there are. Despite
this, refreshes of the browser echo the errors in an open terminal.
The code for the Quote domain class and the controller are below as well. I
wanted to change the config file for the development environment to make it
persistent, so that entry is also down there. Let me know if you need to see
anything else...
Any ideas? (Using Grails version 2.4.0 installed on Ubuntu 14.04. Book uses
code for Grails 1.1)

Yep, as grantmcconnaughey comments, you don't want to declare your controller actions as closures with an '=' sign. It is now recommended to use methods. So you can do:
def random() {
def allQuotes = Quote.list()
}
or:
public random() {
def allQuotes = Quote.list()
}
See the online docs.
Im trying to upload a file, and store it in a file. This is the code in the GSP:
<g:form method="post" enctype="multipart/form-data" action="update">
<input type="file" name="cv" id="cv"/>
<g:actionSubmit action="upload" name="upload" value="Upload" />
</g:form>
In the Controller:
def upload(){
def f = request.getFile('cv')
InputStream file = f.inputStream
byte[] bytes = file.bytes
println('bytes: '+bytes)
}
As I say in the title, i got an exception here. Any help? Thanks.

The problem is that your request is not treated as a MultiPartRequest. Do something like this:
MultipartRequest multipartRequest = request as MultipartRequest
if(multipartRequest){
MultipartFile attachmentFile = multipartRequest.getFile("attachment_file".toString())
if (attachmentFile) {
-- copy it ---
}
}
