             Summary: Seam Transaction is no longer working with servlet containers like Tomcat that don't support CDI injection in listeners
                 Key: SEAMTRANSACTION-15
                 URL: https://issues.jboss.org/browse/SEAMTRANSACTION-15
             Project: Seam Transaction
          Issue Type: Quality Risk
    Affects Versions: 3.1.0.Final
         Environment: Apache Tomcat 7.0.25


            Reporter: Miguel Z
            Assignee: Stuart Douglas


Lack of transaction injection causes:

java.lang.NullPointerException
	org.jboss.seam.transaction.TransactionServletListener.requestInitialized(TransactionServletListener.java:106)
	org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98)

The implementation has changed after SEAM Transaction 3.1.0.Beta5:

https://github.com/seam/transaction/commit/64ef15aee882d8809a42749fc2283a1dd53542be

Instead of a filter there is now a listener doing the job. This "better" implementation excludes all users that use non-EE-containers like Tomcat that don't support @Inject in listeners:

e.g. Tomcat 7.0.25 startup:

...
INFO: Tomcat 7 detected, CDI injection will be available in Servlets and Filters
. Injection into Listeners is not supported
...
