Wildfly 10/infinispan cache

[dhall01]

We have a project which was migrated from JBoss 4 to Wildfly 10. Under JBoss 4, we had multiple caches which were implemented as TreeCaches.

In our current project, those who did the migration defined these caches in the inet-standalone-full.xml, for example:

            <cache-container name="cancache" default-cache="can_last_sent">

                <local-cache name="can_last_sent" jndi-name="java:/atms/cache/can/lastSent">

                    <string-keyed-jdbc-store data-source="AtmsDbData" dialect="MYSQL" passivation="false" preload="true" purge="false" shared="true">

                        <string-keyed-table prefix="cache">

                            <id-column type="NVARCHAR(256)"/>

                            <data-column name="value" type="BLOB"/>

                        </string-keyed-table>

                    </string-keyed-jdbc-store>

                </local-cache>

            </cache-container>

We have a class which formerly used to be used as a key, and implements Serializable. But when we try to use this class as a key, we are getting the error:

2017-06-06 13:59:42,134 ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (Thread-28 (ActiveMQ-client-global-threads-808130985)) ISPN000136: Error executing command GetKeyValueCommand, writing keys []: org.infinispan.persistence.keymappers.UnsupportedKeyTypeException: Unsupported key type: 'com.networks.can.jpa.SentKey' on key: SentKey{alertId=22292, alertCategory='CMS', alertDesc='Comm Failure Detected', notifiedVia=email, address='[e-mail]', alertItem='Comm Failure Detected', hashCode='976212382'}

Is there some configuration we are missing which adds our object as a supported key type?

A <string-keyed-jdbc-store/> can only store cache entries whose keys are of type java.lang.String.

Change this to <binary-keyed-jdbc-store/> and you should be good to go.
