I've deployed my grails application on weblogic server. The front end is grails and backend is using spring and hibernate (not using gorm).
I am seeing the following error when I try to access a static dummy page:
<Dec 11, 2011 5:15:02 AM EST> <Error> <HTTP> <BEA-101362> <[ServletContext#450252357[app: spec-version:2.5]] could not deserialize the request scoped attribute with name: "userService"

Here are the action & controller classes:
class UserAdminController {
def messageSource
def userService
def referenceDataService
def manageUsers = {
render(view: "manageUsers")
}
def showCreateUserAdmin = {
//code goes here
}
}
The reason for writing a dummy action is that the user shouldn't call the gsp page using manageUsers.gsp.
How can I fix this issue?

I'm creating a Grails (3.3.9) plugin to hold shared back-end code for some internal applications. For some reason, when I run the plugin to test it, my service is not being injected into my controller.
I've started with the default web-plugin profile, created a single domain class called Entry, and run generate-all to create a controller, service, and views. When I try to run my plugin as an application and view a single domain instance, I get the following error:
Cannot invoke method get() on null object. Stacktrace follows:

The stacktrace takes me to line 18 in my controller:
def show(Long id) {
respond entryService.get(id)
}
This suggests to me that entryService is null.
My domain class looks like this:
class Entry {
String entryCode
String description
}
The controller is as follows:
class EntryController {
EntryService entryService
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
def index(Integer max) {
params.max = Math.min(max ?: 10, 100)
respond entryService.list(params), model:[entryCount: entryService.count()]
}
def show(Long id) {
respond entryService.get(id)
}
//snipped for brevity
And the service looks like this:
#Service(Entry)
interface EntryService {
Entry get(Serializable id)
//snipped for brevity
}
Based on the Grails plugin documentation, I would expect to be able to run the plugin standalone like any other application, and in normal applications, defining the service as an interface works fine. If I install this plugin to my local maven cache and use it in an application, it works exactly as I would expect; I am able to hit the controller's show endpoint and get back a result from my database.
At one point I tried implementing the service as a class rather than having it be an interface, but then I receive this error:
URI
/entry/index
Class
java.lang.IllegalStateException
Message
null
Caused by
Either class [com.mycompany.internal.Entry] is not a domain class or GORM has not been initialized correctly or has already been shutdown. Ensure GORM is loaded and configured correctly before calling any methods on a GORM entity.
What am I missing about how to set up and run a Grails plugin correctly?
Finally found an answer by digging into the GORM issue: class Authority is not a domain class or GORM has not been initialized correctly or has already been shutdown
Apparently the root of the problem was the need to add compile "org.grails.plugins:hibernate5" to my dependencies block in build.gradle. The weird thing is that the web-plugin profile provides the create-domain-class command, so I would think GORM and Hibernate support would be included by default, but I'm apparently misunderstanding some aspects of how plugins are supposed to work.
As per the grails 3.1.13 guide I am trying to add service dependency to my controller, but somehow it is not working for me. It is throwing NullPointerException for Cannot get property 'serviceMethod' on null object. Below I am mentioning the steps to reproduce.
Execute following commands
grails create-app DepInjectionTest
grails create-controller com.abc.project.KpiReport
grails create-service com.abc.project.KpiReport
Above creates below directory structure
KpiReportService
#Transactional
class KpiReportService {
def serviceMethod() {
return "Hello from KpiReportService"
}
}
KpiReportController
class KpiReportController {
def index() {
def kpiReportService
render kpiReportService.serviceMethod
//render "Hello from KpiReportController"
}
}

I am new to grails, please help me figure out what is going wrong, may be I am missing something.
The error message indicates you are referring to a property that does not exist. Instead of render kpiReportService.serviceMethod you want render kpiReportService.serviceMethod().
Services are injected as class variables
class KpiReportController {
def kpiReportService
def index() {
render kpiReportService.serviceMethod()
//render "Hello from KpiReportController"
}
}
I am using groovy http-builder and using RestClient for accessing web service from JIRA.
In development mode it's working fine but when I deploy war on Tomcat server it throws exception as

How can I fix this issue?
I am added these dependencies in Build Config
compile 'com.atlassian.jira:jira-rest-java-client-api:2.0.0-m25'
compile 'com.atlassian.jira:jira-rest-java-client-core:2.0.0-m25'
and using
AsynchronousJiraRestClientFactory factory = new AsynchronousJiraRestClientFactory()
def jiraServerUri = URI.create("ipaddress")
JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "username", "password")
for authentication and getting RestClient object
Using JIRA REST Client for JAVA in Grails application is not necessary, though it might have resolved your issue. I faced the same issue and was able to create a JIRA REST client with Groovy HTTP Builder.
The only dependency that I added in BuildConfig.groovy was:
dependencies {
compile("org.codehaus.groovy.modules.http-builder:http-builder:0.5.0-RC1") {
excludes 'groovy', 'xml-apis' } }
Then build your JSON query and post your request:
jiraClient.post(requestContentType: JSON, body: query)

I´ve got some weird behaviour using Grails 2.2.4, SpringSecurityCore 2.0 RC in Production on a Tomcat 7 with Groovy Compiler 2.0.8, Java 1.7.0.
We build a plugin which realize basic behaviors. We included the SpringSecurityCore plugin in it with a person class named User. There are some domain classes in the basic plugin which got User fields.
Then we build an application which include our basic plugin. The application got a special application person class called RUser which extend from User. RUser is set to SpringSecurityCore as person class.
Problem:
The application runs about 1 to 3 days without errors, but then ClassCastExceptions are thrown trying to set a RUser object on a User field of a plugin domain class.
User classes:
Plugin User class:
class User implements Serializable {
transient springSecurityService
String username
String password
...
}
Application User class:
class RUser extends User implements Serializable{
Cart cart
boolean businessUser = false
boolean taxIncluded = false
...
}
Application Config.groovy:
grails.plugin.springsecurity.userLookup.userDomainClassName = 'RUser'
Participated classes of our basic plugin:
class UserRole implements Serializable {
User user
Role role
static UserRole create(User user, Role role, boolean flush = false) {
new UserRole(user: user, role: role).save(flush: flush, insert: true)
}
...
}
class UserHistory implements Serializable{
User user
List historyEntries
static hasMany = [historyEntries:HistoryEntry]
...
}
The errors occur in this example situations:
In a Filter:
54: UserHistory.withTransaction{
def currentUser =springSecurityService.currentUser
def history = UserHistory.findByUser(currentUser)
if(!history){
96: history = new UserHistory(user:user).save(flush:true)
}
}

The ClassCastExceptions occurs everywhere, where an object with type RUser is setted on a User field. The RUser object is retrieved from springSecurityService.currentUser or with the lookupUserClass().findBy(...) method.
protected Class<?> lookupUserClass() {
grailsApplication.getDomainClass(lookupUserClassName()).clazz
}
As mentioned before, the application runs without errors for a undefined period of time in a production environment (no reloading, no config changes). A new deployment of the same war solves the problem for the next few hours/days.
Any suggestions?

I have used WSClient on my Grails application by adding groovyws-standalone-0.3.1.jar in lib folder of my project.
Added the following code in my controller:
import groovyx.net.ws.WSClient
....
....
def wsdlUrl = "url_Of_webservice?wsdl"
def payLoad = "list_Of_Parameters"
def result = ''
def proxy = new WSClient(wsdlUrl , this.class.classLoader)
try{
proxy.initialize()
result = proxy.getallvendorsbyurl(payLoad)
}
catch (java.lang.NullPointerException e){
println "proxy not initialize"
}
It is working fine in localhost but when i deploy it on tomcat6 server, it starts throwing exception :
On server logs:
