Error on implementing spring-saml-security with WSO2 - spring-security

Question

I am trying to implement SAML 2.0 is my application, by using my app as a service provider and WSO2 server as an idp. I have downloaded and implemented the spring-security-saml2-sample application and I have modified it to work with WSO2 server as idp and the sample application works as expected.
I am now trying to incorporate securityContext.xml and the related configurations into my application, however I am getting an exception during metadata generation.
The exception is as follows:
java.lang.IllegalArgumentException: Manager with name 'MetadataKeyInfoGenerator' does not exist
at org.opensaml.xml.security.keyinfo.NamedKeyInfoGeneratorManager.getFactory(NamedKeyInfoGeneratorManager.java:157)

I have not made any major changes to the sample applications securityContext.xml. Has anyone encountered any similar errors. Any help would be much appreciated.
Please find below my entire securityContext.xml

I have included SAMLBootstrap in the context.xml

Answer 1

Might be helpful for others. I faced similar issue and the reason this occurred was that another piece of legacy code in the system was re-instantiating OpenSAML library by invoking DefaultBootstrap.bootstrap();
Since SpringSAML already initializes it during container bootstrapping, had to remove initialization from legacy code

Answer 2

Having the complete securityContext.xml in your question would really help. But first of all make sure it contains the following bean, as the exception seems to indicate that the initialization login in SAML bootstrap wasn't executed:
<bean class="org.springframework.security.saml.SAMLBootstrap"/>
Also, try changing the bean to:
<bean class="org.springframework.security.saml.SAMLBootstrap" lazy-init="false"/>
