InvalidPropertyException when using Grails and Spring security core plugin - grails

I have added the spring core security plugin (tried both 1.2.1 and 1.2.7.3)
to a grails 1.3.7 app.
then
s2-quickstart sim GUser GRole

Please can you let me know how to resolve this?

Thanks,

I suspect there is a problem with the capitalization routine and it is tripping up over class names like GUser and GRole. Try naming them GrUser and GrRole (or anything that doesn't start with 2 upper case letters). Grails 1.3.7 is very old and there were issues early on with GrailsNameUtils not doing the right thing with names like those.

How to configure multipart in Grails?

I'm using Servlet 3.0 and the Spring Security REST plugin in my Grails application. When I run the application in Glassfish and when the security plugin looks for the access token in a request, the following exception is thrown:
java.lang.IllegalStateException: Request.getParts is called without multipart configuration. Either add a #MultipartConfig to the servlet, or a multipart-config element to web.xml

Where do I have to place the multipart configuration?
I'm not uploading a file, so I guess I can't use the annotation. But there's also no web.xml in Grails.
I'm using Grails 2.5.0 and GlassFish 4.1
Thanks in advance!

NullPointerException when running Spring Data Neo4j in Advanced Mapping mode (Aspectj)

I've been trying to configure Spring Data Neo4j to use the Advanced Mapping mode with AspectJ but I've not been able to get it to work properly with my Spring Boot project. The project compiles and starts up without exception but when I try to call a controller I get a java.lang.NullPointerException. I've compared my code with some of the example projects and I cannot see what I'm doing wrong.
I've put up a small example program that highlights the issue on github: https://github.com/tjakobsen/nullpointer
Below is a copy of the full stack trace I get when I run the above project (I'm using JDK 1.7 with Tomcat 7). Any insight on what I'm doing wrong would be much appreciated.

I think you're missing the neo4j aspect configuration. Check this out https://github.com/inserpio/nullpointer and let me know if it correctly works also for you.

Searching the internet hasn't turned up anything useful. Any help troubleshooting this would be greatly appreciated. I'm using Grails version 2.0.3 and Jetty version 7.6.3.
Here is my datasource config for the grails app:
dataSource {
dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
pooled = true
url = "jdbc:as400://localhost;naming=system;libraries=*LIBL;errors=full"
driverClassName = "com.ibm.as400.access.AS400JDBCDriver"
username = "user"
password = "pass"
dialect = org.hibernate.dialect.DB2400Dialect.class
}
It may help to note that I am using the systemitools plugin for Grails.
UPDATE: I removed all other webapps so that mine would be the only webapp run when jetty starts and it worked fine. The problem seems to be when a different webapp starts before the grails app.
Don't have Spring create the Data Source.
That's against the rules with the Servlet Spec.
Have Spring just reference the JNDI DataSource that you have defined in the webapp container.
1) The real server side / container DataSource
Setup the server side JNDI reference to the real javax.sql.DataSource, call it anything you want (in this example, we'll call it jdbc/myContainerDS)
Use the documentation at http://wiki.eclipse.org/Jetty/Howto/Configure_JNDI_Datasource
2) The WEB-INF/web.xml resource-ref
You must setup the <resource-ref> reference in web.xml (this is a required part of the servlet spec that some webapp containers fail to follow). Again, use the documentation above for help.
3) The Spring bean reference to the JNDI provided DataSource
Setup the Spring side bean to reference the JNDI datasource on the server side.
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/myContainerDS"/>
<property name="lookupOnStartup" value="false"/>
<property name="cache" value="true"/>
<property name="proxyInterface" value="javax.sql.DataSource"/>
</bean>
I found a work-around at least. If I change my database driver in my datasource to use db2 instead of as400 (and change the url accordingly) then everything is fine. I had tried converting the webapps to Grails hoping that it would solve the problem, but it didn't. Not until I switched to using the db2 driver instead of the as400 driver.
com.ibm.db2.jdbc.app.DB2Driver
Multiple apps using the db2 driver is fine. Some apps using db2 and one using as400 is fine. Multiple apps using the as400 driver is not fine.
I'm still not sure exactly why that is. If someone has an idea then please comment.

What does this exception mean?

I am getting this message while building my Grails app with MAVEN, After bootstrap is done I am getting this exception on my logs. Can someone direct me where to look for the cause of this exception? What does it trying to say ?

Without having any source code or your version of Grails, just looking at your Exception stacktrace, the following stuck out:
Error creating bean with name 'instanceControllersApi': Singleton bean creation not allowed while the singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)
I did a bit of research into Grails JIRA and the following JIRA issue GRAILS-8645 had the same stacktrace as you did. Take a look at the stacktrace on this JIRA issue. Per the JIRA issue, it appears to affect Scaffolding in 2.0 final, but is fixed with 2.0.1.
