[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1952) persistenceUnitProperties on EntityManagerFactory must be parameterized

persistenceUnitProperties on EntityManagerFactory must be parameterized ----------------------------------------------------------------------- Key: JBSEAM-1952 URL: http://jira.jboss.com/jira/browse/JBSEAM-1952 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 2.0.0.CR1 Reporter: Dan Allen Assigned To: Pete Muir Priority: Minor Fix For: 2.0.0.CR2 Attachments: JBSEAM-1952-v1.txt Original Estimate: 30 minutes Remaining Estimate: 30 minutes The XML configuration schema boast support for persistence-unit-properties on the EntityManagerFactory component. However, the configuration does not work because persistenceUnitProperties is not parameterized and therefore the Seam map converter cannot figure out what to do. If key/value pairs are specified, Seam fails to start. Here is an example: <persistence:entity-manager-factory name="emf" persistence-unit-name="pu"> <persistence:persistence-unit-properties> <key>hibernate.hbm2ddl.auto</key> <value>create-drop</value> </persistence:persistence-unit-properties> </persistence:entity-manager-factory> Here is the exception that is thrown: Caused by: java.lang.IllegalArgumentException: collection type not parameterized at org.jboss.seam.util.Reflections.getCollectionElementType(Reflections.java:188) at org.jboss.seam.Component$MapInitialValue.<init>(Component.java:2457) at org.jboss.seam.Component.getInitialValue(Component.java:526) at org.jboss.seam.Component.getTopInitialValue(Component.java:510) at org.jboss.seam.Component.initInitializers(Component.java:488) at org.jboss.seam.Component.<init>(Component.java:260) at org.jboss.seam.Component.<init>(Component.java:214) at org.jboss.seam.init.Initialization.addComponent(Initialization.java:940) Unfortunately, the best option we have, from the converters that Seam supports, is to make it a Map<String, String>. In the patch supplied I have used this signature.
