I have been trying to upgrade spring-flex 1.0.3 to 1.5.2 in order to check new features, i.e. Hibernate lazy fetching support in BlazeDS 4. I downloaded all necessary packages, changed dependencies in Maven for Spring (to 3.0.7), Hibernate (to 3.6.9) and Spring flex core (to 1.5.2). When I try to build and deploy application, I got NullPointerException which indicates cause in my domain class (at the end of stack trace):

I appreciate any supportive replies.
It comes from your code :
com.educationathome.domain.Device.toString(Device.java:182)
so check this line, and check what can be null.

I am running wso2is Version 5.7 and tried to implement a TokenGenerator based on msf4j JWTAccessTokenBuilder.

<AccessTokenValueGenerator>org.wso2.carbon.identity.oauth.tokenvaluegenerator.SHA256Generator</AccessTokenValueGenerator>

Can anybody give me a hint?
As per the error com.nimbusds.jwt.ReadOnlyJWTClaimsSet cannot be found by JWTAccessTokenBuilder_2.7.4.SNAPSHOT, it is due to the OSGi class binding.
In the maven-bundle-plugin configuration Import-Package of the pom, make sure you have the com.nimbusds.jwt with the correct version range.
Or the quick fix is to add <DynamicImport-Package>*</DynamicImport-Package>
I found the problem:
I used an old version of org.wso2.carbon.identity.inbound.auth.oauth2
I updated the pom.xml to
<dependency>
<groupId>org.wso2.carbon.identity.inbound.auth.oauth2</groupId>
<artifactId>org.wso2.carbon.identity.oauth</artifactId>
<version>6.0.172</version>
<scope>provided</scope>
</dependency>
from https://mvnrepository.com and had to update the code to use the version of com.nimbusds.jwt used by wso2is.
And finally in the service provider settings you must select the Token Issuer.

As far as I understand, Spring MVC’s dispatcher servlet complains that there are two controllers (SingleArticleController and ArticleViewController) mapped to the same view (/viewArticle.jsp). But I triple-checked and there is only one servlet mapped to this view, which is ArticleViewController.
The problem is, SingleArticleController simply does not exists in the project; I guess it’s the name of an old servlet that was removed, or maybe the old name of the controller currently mapped to the view.
How can I resolve this conflict?
edit: I have already tried to clean the project and the Tomcat working dir but it didn't help
Eventually, I solved this problem: the class SingleArticleController was not showing up anywhere in Eclipse, however for some reason it was still in my workspace, under the controllers folder. Once I deleted it from the folder, the application worked again.
Apparently both the Eclipse clean and the Maven clean failed to solve this problem, so I had to delete the file manually from the workspace.
Getting error while executing program in Eclipse:
og4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
