Error deploying grails portlet on liferay 6 - grails

I want to test a simple liferay portlet with grails.
I am using: Liferay version liferay-portal-6.1.1-ce-ga2 that has tomcat version
tomcat-7.0.27 embedded , Grails 2.1.0 , IDE Groovy/Grails Tool Suite Version: 3.0.0.RELEASE andJDK1.7.0_05
I have instaled plugins.portlets=0.9.2 and plugins.portlets-liferay=0.4
After installing the grails plugins in a project i simply ran the following commands: create-portlet directorio.testLiferay and generate-portlet-views directorio.testLiferay
I have configurated Config.groovy following like http://grails.org/plugin/portlets-liferay
My portlet class looks like follow:
package directorio
import javax.portlet.*
class TestLiferayPortlet {
def title = 'Grails test'
def description = '''Portlet de pruebas.'''
def displayName = 'GrailsTest'
def supports = ['text/html':['view', 'edit', 'help']]
//uncomment to declare events support
//def events = [publish: ["event-1"], process: ["event-2"]]
//uncomment to declare public render parameter support
//def public_render_params = ["prp-1","prp-2"]
// DEFINITIONS FOR liferay-display.xml
def liferay_display_category = 'SCRD'
// DEFINITIONS FOR liferay-portlets.xml
def liferay_portlet_ajaxable = 'true'
def liferay_portlet_header_portlet_css = [
'/css/protoFlow.css'
]
def liferay_portlet_header_portlet_javascript = [
'/plugins/richui-0.5/js/flow/lib/prototype.js',
'/plugins/richui-0.5/js/flow/lib/scriptaculous.js',
'/plugins/richui-0.5/js/reflection/reflection.js',
'/plugins/richui-0.5/js/flow/protoFlow.js'
]
def actionView = {
//TODO Define action phase for 'view' portlet mode
portletResponse.setRenderParameter("prp-1", "value-1");
}
def eventView = {
//TODO Define event phase for 'view' portlet mode.
def eventValue = portletRequest.event.value
}
def renderView = {
//TODO Define render phase for 'view' portlet mode.
//Return the map of the variables bound to the view,
//in this case view.gsp if it exists or render.gsp if not
['mykey':'myvalue']
}
def resourceView = {
//TODO define resource phase for 'view' portlet mode.
//Render HTML as response
render {
html {
head()
body {
"Render me!!"
}
}
}
}
def actionEdit = {
//TODO Define action phase for 'edit' portlet mode
portletResponse.setEvent("event-1","event-1")
portletResponse.setPortletMode(PortletMode.VIEW)
}
def renderHelp = {
//TODO Define render phase for 'help' portlet mode
//Return the map of the variables bound to the view,
//in this case help.gsp if it exists or render.gsp if not
['mykey':'myvalue']
}
def doResource = {
//TODO Define handling for default resource URL handling method, independent of porlet mode
//Return the map of the variables bound to the view,
//in this case resource.gsp
['mykey':'myvalue']
}
//invoked by setting 'action' param in resourceURL (as an example) to 'doSomethingAjaxy'
def doSomethingAjaxy = {
//render JSON
render(contentType:"text/json") {
example(mykey:"myvalue")
}
}
//invoked by setting 'action' param in eventURL (as an example) to 'handleThisEvent'
def handleThisEvent = {
//render thisEvent.gsp
render(view:"thisEvent")
}
}
If i execute run-app and war, it works fine. However when i put the war into deploy liferay directory and startup tomcat, i get error:
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

I really apreciate any help.
Many tx.

It's a bug in liferay 6.1.1
http://issues.liferay.com/browse/LPS-29103
It appears hot deployment rearranges the listeners in web.xml when it merges it.
Might be better to stick with 6.1.0, or manually fix the web.xml everytime you redeploy

Add compile 'javax.portlet:portlet-api:2.0' in your dependencies of BuildConfig.groovy
:D

MissingPropertyException in groovy enum values iterator

Groovy code in the Grails project throws MissingPropertyException during values collection find() iteration. It doesn't happen every time, only sometimes and I didn't find the case during which the MissingPropertyException happens.
Here is the enum class:
public enum SurveyStateTransitions {
TRANSITION_ONE(SurveyState.UNDEFINED, [SurveyState.ACQUISITION, SurveyState.PROCESSING] as Set),
TRANSITION_TWO(SurveyState.ACQUISITION, [SurveyState.PROCESSING, SurveyState.ARCHIVED] as Set),
private SurveyState current
private Set<SurveyState> transitions
SurveyStateTransitions(SurveyState current, Set<SurveyState> transitions) {
this.current = current
this.transitions = transitions
}
public static Set<SurveyState> getTransitions(SurveyState current) {
values().find { it.current == current }.transitions
}
}
And here is the row, where the exception is actually thrown:
values().find { it.current == current }.transitions
The whole stacktrace:

Grails "Template not found error"

I am getting the following error when trying to render my GSP (using Grails 2.3.6):
org.codehaus.groovy.grails.web.taglib.exceptions.GrailsTagException: Template not found for name [/shared/mymenu] and path [/shared/_mymenu.gsp]
...long stacktrace omitted
java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
java.lang.Thread.run(Thread.java:745)
Inside the /shared/_mymenu.gsp:
<g:render template="/shared/mmenustub" model="${['root':appmenu]}">
</g:render>
Am I missing something here? Perhaps a plugin attribute or something? If so, what am I missing and what should its value be?
The globalmenu taglib is define as follows:
class GlobalMenuTagLib {
def globalmenu = { attrs, body ->
List<NavigationScheme> allNavigationSchemes = navigationSchemeService.listAll()
def mapped = allNavigationSchemes.groupBy { menu -> menu.appreference }
def registeredApps = registerInfoService.listAllActive()
def activePage = attrs.activepage
def tempName = attrs.tempName?:'anothermenu'
out << render(template: "/shared/$tempName", model:[navscheme: mapped, regApps: registeredApps, activepage:activePage])
}
}
It is failing to find the /shared/_mymenu.gsp file. If this file exists in a plugin, then you need to reference it with the "plugin" argument in the render method so that it knows where to search for the file.
out << render(template: "/shared/$tempName", model:[navscheme: mapped, regApps: registeredApps, activepage:activePage], plugin: "myplugin")
where "myplugin" is the name of your plugin.

Expired activiti jobs throwing exception while server startup - Grails

This is with regard to activiti workflow timer jobs in grails application.
While starting the grails app with expired jobs, exception is thrown for normal grails features such as log and methods of domain classes.
For eg:
Caused by: groovy.lang.MissingPropertyException: No such property: log for class: com.service.common.UtilityService
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:49)
at org.codehaus.groovy.runtime.callsite.PogoMetaClassGetPropertySite.getProperty(PogoMetaClassGetPropertySite.java:50)

This happens in dev environment running the app from Spring STS. We are using activiti plugin 5.8.2 for grails (1.3.6)
After the web-app is started up completely, the jobs (schedule to a time after startup) run properly and no missing property exception is thrown.
Even though we can fix the of missing property issue for log by using private static final log = LogFactory.getLog(this) instead, then any reference to domain classes throw an error, like using get or find method.
eg:
Caused by: groovy.lang.MissingMethodException: No signature of method: static com.domain.wr.WorkRequest.read() is applicable for argument types: (java.lang.String) values: [44700]
Possible solutions: getId(), getAt(java.lang.String), setId(java.lang.Long), grep(java.lang.Object), each(groovy.lang.Closure), find(groovy.lang.Closure)

Activiti Configuration
Config.groovy
// Added by the Grails Activiti plugin:
activiti {
processEngineName = "activiti-engine-default"
databaseType = "oracle"
deploymentName = appName
history = "audit" // "none", "activity", "audit" or "full"
sessionUsernameKey = "username"
useFormKey = true
deploymentResources = ["classpath:activiti/escalation/WorkRequest.bpmn20.xml"]
}
Config.properties
activiti.processEngineName =activiti-engine-default
activiti.databaseSchemaUpdate =true
activiti.jobExecutorActivate =true
activiti.mailServerHost = "mail1.net"
activiti.mailServerPort = 25
activiti.mailServerUsername = ""
activiti.mailServerPassword = ""
activiti.mailServerDefaultFrom = ""
This is killing my application as a downtime makes the workflow unusable with timer tasks.
I had more or less the same problem, and in our case was caused by Activiti starting jobs execution before Spring injection being finished. That's why it only happens at startup: the job is accessing properties that are not there yet.
You can confirm that you are in the same situation by increasing the RETRIES_ in the ACT_RU_JOB table after the app has finished bootstraping and see if the jobs execute successfully.
If this is your case, I think the only option is to upgrade the plugin and if still fails, create a bug.
This issue got solved.
1) Edit Config.groovy and disable activiti during startup
activiti {
processEngineName = "activiti-engine-default"
databaseType = "oracle"
disabled = true
deploymentName = appName
sessionUsernameKey = "username"
useFormKey = true
deploymentResources = []
}
2) add the initialization of Activiti Objects in the init method of User BootStrap
def init = { servletContext ->
org.springframework.context.ApplicationContext ctx = ServletContextHolder.getServletContext().getAttribute(GrailsApplicationAttributes.APPLICATION_CONTEXT)
def bb = new grails.spring.BeanBuilder(ctx)
bb.beans {
//println "Activiti Process Engine Initialization..."
customDbIdGenerator(com.mycompany.activiti.customDbIdGenerator){
idBlockSize=CH.config.activiti.idBlockSize?:100
}
processEngineConfiguration(org.activiti.spring.SpringProcessEngineConfiguration) {
processEngineName = CH.config.activiti.processEngineName?:ActivitiConstants.DEFAULT_PROCESS_ENGINE_NAME
databaseType = CH.config.activiti.databaseType?:ActivitiConstants.DEFAULT_DATABASE_TYPE
databaseSchemaUpdate = CH.config.activiti.databaseSchemaUpdate ? CH.config.activiti.databaseSchemaUpdate.toString() : ActivitiConstants.DEFAULT_DATABASE_SCHEMA_UPDATE
deploymentName = CH.config.activiti.deploymentName?:ActivitiConstants.DEFAULT_DEPLOYMENT_NAME
deploymentResources = CH.config.activiti.deploymentResources?:ActivitiConstants.DEFAULT_DEPLOYMENT_RESOURCES
jobExecutorActivate = CH.config.activiti.jobExecutorActivate?:ActivitiConstants.DEFAULT_JOB_EXECUTOR_ACTIVATE
history = CH.config.activiti.history?:ActivitiConstants.DEFAULT_HISTORY
mailServerHost = CH.config.activiti.mailServerHost?:ActivitiConstants.DEFAULT_MAIL_SERVER_HOST
mailServerPort = CH.config.activiti.mailServerPort?:ActivitiConstants.DEFAULT_MAIL_SERVER_PORT
mailServerUsername = CH.config.activiti.mailServerUsername
mailServerPassword = CH.config.activiti.mailServerPassword
mailServerDefaultFrom = CH.config.activiti.mailServerDefaultFrom?:ActivitiConstants.DEFAULT_MAIL_SERVER_FROM
dataSource = ref("dataSource")
transactionManager = ref("transactionManager")
idGenerator= ref("customDbIdGenerator")
}
processEngine(org.activiti.spring.ProcessEngineFactoryBean) {
processEngineConfiguration = ref("processEngineConfiguration")
}
runtimeService(processEngine:"getRuntimeService")
repositoryService(processEngine:"getRepositoryService")
taskService(processEngine:"getTaskService")
managementService(processEngine:"getManagementService")
identityService(processEngine:"getIdentityService")
historyService(processEngine:"getHistoryService")
formService(processEngine:"getFormService")
activitiService(org.grails.activiti.ActivitiService) {
runtimeService = ref("runtimeService")
taskService = ref("taskService")
identityService = ref("identityService")
formService = ref("formService")
}
}
println "## Registering Beans ##";
bb.registerBeans(ctx);
ctx.getBean("processEngine");
println "Bean Count2 "+ctx.getBeanDefinitionCount();
}

GRAILS: groovy.lang.MissingPropertyException: No such property.

I'm trying to debug a Grails application. Unfortunately, I have no prior experience in said language.
When I do grails generate-all org.example.Book, I get back a vague error:
Generating controller for domain class org.example.Book ...
groovy.lang.MissingPropertyException: No such property: Event for class: SimpleTemplateScript6

Error running generate-all: No such property: Event for class: SimpleTemplateScript6
After looking at the generated org.example.BookController.groovy source, I noticed that it was not fully generated (stopped at List fields = []):
package org.example
// import needed for export plugin
import org.codehaus.groovy.grails.commons.ConfigurationHolder
class BookController {
...
def exportService
def export = {attrs ->
def response = attrs.response
List fields = []
This error appears to be caused by the following code in templates/scaffolding/Controller.groovy:
<%=packageName ? "package ${packageName}\n\n" : ''%>
// import needed for export plugin
import org.codehaus.groovy.grails.commons.ConfigurationHolder
class ${className}Controller {
static allowedMethods = [save: "POST", update: "POST", delete: "POST"]^M
def exportService
...
def export = {attrs ->
def response = attrs.response
List fields = []
<% excludedProps = Event.allEvents.toList() << 'version'
allowedNames = domainClass.persistentProperties*.name << 'id' << 'dateCreated' << 'lastUpdated'
props = domainClass.properties.findAll { allowedNames.contains(it.name) && !excludedProps.contains(it.name) && !Collection.isAssignableFrom(it.type) }
Collections.sort(props, comparator.constructors[0].newInstance([domainClass] as Object[]))
props.eachWithIndex {p, i -> %>fields.push("${p.name}"<%="\n"%><% } %>
Map labels = [:]
<% props.eachWithIndex { p, i -> %>labels.putAt("\${p.name}", "\${p.naturalName}")<%="\n "%><% } %>
Map formatters = [:]
Map parameters = [:]
response.setHeader("Content-disposition", "attachment; filename=${domainClass.propertyName}s.\${attrs.extension}")
if("\${attrs.extension}" == "xml") {
exportService.export(attrs.format, response.outputStream, attrs.exportList, fields, [:], formatters, parameters)
} else {
exportService.export(attrs.format, response.outputStream, attrs.exportList, fields, labels, formatters, parameters)
}
}
...
}
It appears that the def export {} block seems to be causing problems. Is there something wrong with the above code?
What is the Event class? Is there an import for it?
Check your domain class for syntax errors. Make sure that in your domain class, you've included necessary packages, in your case, package org.example.
