[jboss-jira] [JBoss JIRA] (WFLY-7973) WildFlyDataSource needs implementation of isWrapperFor method

[Ivo Studensky (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13354250#comment-13354250 ] 

Ivo Studensky commented on WFLY-7973:
-------------------------------------

I am really not sure the attached reproducer is valid. {{org.jboss.as.connector.subsystems.datasources.WildFlyDataSource}} you get from lookup does not implement XADataSource directly. It is a wrapper with {{unwrap}} method unsupported, i.e. {{isWrapperFor}} should always return {{false}}, see javadoc for {{java.sql.Wrapper}}.

Moreover, I can't see any way how to determine from {{delegate}} WildFlyDataSource consist of if the proxy represents an XA datasource or non-XA datasource. The {{delegate}} is in fact {{org.jboss.jca.adapters.jdbc.WrapperDataSource}} which does not seem to contain any information if it belongs to XA or non-XA datasource. It neither contains any XA/non-XA datasource instance that can be returned from {{JBossWrapper.getWrappedObject}}.

I recall similar questions from the past, I will try to look around for any forum post related to this.
