servicemix change karaf password

I have a ServiceMix 5.3.2 instance running.
I have changed the karaf password changing the etc/users.properties file as following:
karaf = karaf_2,_g_:admingroup
The problem is that when I use the activemq webconsol I have this exception in the log

I think I have to change the default password for the webconsole but I do not understand how to do this.
I tried to change the file etc/org.apache.activemq.webconsole.cfg but without success.
Thanks in advance

Using an account with ROLE_USER on the same page I do not get this error.
When I restart the server the error for the ROLE_ADMIN and ROLE_USER user is gone. There might be some caching problem or so.
How do I fix this error?
Edit: Here is the GSP I requested:
some html code
<g:include controller="adminUser" action="myUsers" />
My controller uses Spring Security Annotation:
#Secured(AccessRole.ROLE_USER)
class AdminController {
def index() {}
}
Edit: Here is the content of the GSP I include:
<%# page import="test.Hotel" %>
<g:each in="${hotels}" var="hotel">
<g:render template="hotel" model="[hotel: hotel]" />
</g:each>

I still need to see your GSP's at least, but I would bet your problem is related to the use of <g:include> and how you are using the SpringSecurity.
Could you try to remove the <g:include> tags from your pages and running your tests again?
The problem with that is that Spring Security is implemented with Servlet filters and you're including secured content after the check.
Possible workarounds:
Try to use Spring Security taglibs with your includes, or don't using
includes at all.
Another solution is to refactor your pages to load
your fragments with ajax.
For example, enclose your includes with spring security tags, to show only if the user has the correct roles:
<sec:ifAnyGranted roles="ROLE_USER">
<g:include controller="adminUser" action="myUsers" />
</sec:ifAnyGranted>
[]'s

Message: Unable to find ACL information for object identity 'org.springframework.security.acls.domain.ObjectIdentityImpl[Type: majestella.Company; Identifier: 50e396b8eebefc5a84]'
You haven't created the acl entries for majestella.Company with id 50e396b8eebefc5a84 in your database. Each records needs to have its permission registered on acl entries and related tables.

I still have no answer to this question but as a work around I deleted:
<g:include controller="adminUser" action="myUsers" />

This usually happens when there's an error in the Domain, Controller or Service classes. run with --stacktrace and you'll find the root cause

This isn't much of an answer, but I just experienced this error and was able to get rid of it with a grails clean and grails compile.

Grails, Jobs, Static Helper Methods and Hibernate Session

I have a Grails job-class (grails-app/jobs) who needs to call a static (helper) method (defined in src/groovy). This method calls get- and find-methods respectively on 2 different domain-objects. The result of the method call is returning a simple String (could return anything for that sake - doesn't matter).
My question is, how do I use .withTransaction or .withSession in the job-class when I'm calling a static method containing fetch of 2 (could be more) different domain-classes?
Or, how do I declare/use a Hibernate session in a job-class so that I don't have to use .withBlaBla?
EDIT (another EDIT at the bottom - sorry):
The lines where EZTable and EZRow is fetched is working. EmailReminder I had to wrap with EmailReminder.with... Now the lines with call to ServiceUtils.handleSubjectOrMessageString(ezTable, ezRow, emailReminder.subject) are causing an exception (this is added "now" - the entire job-class was working earlier with simple String-values).
class EmailReminderJob implements Job {
EmailReminder emailReminder
EZTable ezTable
EZRow ezRow
static triggers = {}
def void execute(JobExecutionContext context) {
List<String> emails = new ArrayList<String>(0)
ezTable = EZTable.get(new Long(context.mergedJobDataMap.get('ezTableId')))
ezRow = EZRow.get(new Long(context.mergedJobDataMap.get('ezRowId')))
EmailReminder.withTransaction { status ->
emailReminder = EmailReminder.get(new Long(context.mergedJobDataMap.get('emailReminderId')))
if(emailReminder.sendMessageToOwnerUser && emailReminder.ownerUser.email!=null)
emails.add(emailReminder.ownerUser.email)
if(emailReminder.sendMessageToOwnerCompany && emailReminder.ownerCompany.email!=null)
emails.add(emailReminder.ownerCompany.email)
if(emailReminder.emails!=null && emails.size()>0)
emails.addAll(new ArrayList<String>(emailReminder.emails))
if(emailReminder.messageReceiverUsers!=null && emailReminder.messageReceiverUsers.size()>0) {
for(user in emailReminder.messageReceiverUsers) {
if(user.email!=null)
emails.add(user.email)
}
}
}

EDIT AGAIN :( :
I have many nested calls in my static method (fetchCellValues(ezcell, ezcolumn) in the matcher.appendReplacement(stringBuffer, fetchCellValues(ezcell, ezcolumn))-method is calling deeper to fetch values and I actually get a "no Session"-exception at one call (call regular as all the other calls trying to fetch another domain-object):
Message: org.quartz.SchedulerException: Job threw an unhandled exception. [See nested exception: org.hibernate.LazyInitializationException: could not initialize proxy - no Session]

You use them like you would anywhere. Both are independent of the class they're called on; withTransaction just runs the wrapped code in a transaction, joining a current active transaction if there is one, and withSession makes the current Hibernate Session available to the wrapped code but otherwise doesn't do anything.
You don't indicate any reason for needing either, so it's not obvious what to advise specifically. You don't need a transaction if you're only reading data, and if you're calling domain class methods you shouldn't need access to the session.
One use for withTransaction that I've advocated in the past (pretty much the only use for it since it's typically misused) is to avoid lazy loading exceptions when there isn't an active session already. Wrapping code in a withTransaction block has the side effect of creating a session and keeping it open for the duration of the block and that lets you work with lazy-loaded instances and collections. Controllers have an active session because there's an open-session-in-view interceptor that starts a session at the beginning of the request, stores it in a ThreadLocal, and flushes and closes it at the end of the request. Jobs are similar because the plugin uses Quartz job start/end events to do the same thing.
But whether you are making your code transactional because of lazy loading or because you're updating, you should usually be doing the work in a transactional service.
Services are great for transactional work because they're transactional by default (only services that have no #Transactional annotations and include static transactional = false are non-transactional), and it's easy to configure transaction demarcation per-class and per-method with the #Transactional annotation. They are also great for encapsulating business logic, independent of how they're called; there's usually no need for a service method to have any HTTP/Job/etc. awareness, just pass it the data needed in String/number/boolean/object arguments and let it do its work.
I like to keep controllers simple, doing data binding from the request params and calling services to do the real work, then rendering a response or routing to the next page, and I do the same thing in Quartz jobs. Use Quartz for its scheduling functionality, but do the real work in a service. Dependency-inject the service like any bean (def fooService) and put all of the business logic and database work there. It keeps things cleanly delineated in the code, and makes testing easier since you can test the service methods without having to mock HTTP calls or Quartz.

Grails dynamic scaffolding error

I am new to Grails, I installed Grails 2.4 on Ubuntu 14.04
I have this Grails Domain:
class EndUser {
String username
String password
String fullName
String toString() {
"$fullName"
}
static hasMany = [projects: Project, tasks: Task]
static constraints = {
fullName()
username()
password()
}
}
and it's controller:
class EndUserController {
static scaffold = true
def index = {
// redirect(action: "list")
}
}
I am getting the error below, and everytime i create a new EndUser, I am getting an error page showing this message:
Error 500: Internal Server Error
URI
/ProjectTracker/endUser/create
Class
java.lang.NullPointerException
Message
null
What did I do wrong? and how can I fix it?
Please let me know if I need to provide more info.

Thanks,

It looks like you hit this bug: https://jira.grails.org/browse/GRAILS-11430. It will be fixed in Grails 2.4.1; you can either wait until that version is released or try the workaround provided in the comments of that link, which has been reported to work.
