Hello, I am trying to JBoss Cache working with a Firebird database using the Jaybird JDBC driver. However, when I start up my example I get the following exception (see below). I am sure this is because of the BLOB type size limitations, however I'm not entirely sure. I know there is a workaround for Mysql to use "longblob" instead of "blob" in the configuration file. Is there something similar for Firebird? Any help is greatly appreciated. Thanks, Ryan Exception in thread "main" org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544351. unsuccessf ul metadata update key size too big for index JBOSSCACHE_PK at org.firebirdsql.jdbc.AbstractStatement.executeUpdate(AbstractStatement.java:281) at org.jboss.cache.loader.JDBCCacheLoader.start(JDBCCacheLoader.java:726) at org.jboss.cache.loader.AsyncCacheLoader.start(AsyncCacheLoader.java:303) at org.jboss.cache.loader.CacheLoaderManager.startCacheLoader(CacheLoaderManager.java:353) at org.jboss.cache.TreeCache.startService(TreeCache.java:1413) at org.jboss.cache.aop.PojoCache.startService(PojoCache.java:94) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:274) at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:181) at TestCache1.main(TestCache1.java:25) at org.firebirdsql.gds.GDSException: unsuccessful metadata update key size too big for index JBOSSCACHE_PK at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.readStatusVector(AbstractJavaGDSImpl.ja va:2113) at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.receiveResponse(AbstractJavaGDSImpl.jav a:2063) at org.firebirdsql.gds.impl.wire.AbstractJavaGDSImpl.iscDsqlExecute2(AbstractJavaGDSImpl.jav a:1155) at org.firebirdsql.gds.impl.GDSHelper.executeStatement(GDSHelper.java:223) at org.firebirdsql.jdbc.AbstractStatement.internalExecute(AbstractStatement.java:1109) at org.firebirdsql.jdbc.AbstractStatement.executeUpdate(AbstractStatement.java:277) at org.jboss.cache.loader.JDBCCacheLoader.start(JDBCCacheLoader.java:726) at org.jboss.cache.loader.AsyncCacheLoader.start(AsyncCacheLoader.java:303) at org.jboss.cache.loader.CacheLoaderManager.startCacheLoader(CacheLoaderManager.java:353) at org.jboss.cache.TreeCache.startService(TreeCache.java:1413) at org.jboss.cache.aop.PojoCache.startService(PojoCache.java:94) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:274) at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:181) at TestCache1.main(TestCache1.java:25) Configuration file: org.jboss.cache.loader.JDBCCacheLoader <!-- same as the old CacheLoaderConfig attribute --> cache.jdbc.table.name=jbosscache cache.jdbc.table.create=true cache.jdbc.table.drop=true cache.jdbc.table.primarykey=jbosscache_pk cache.jdbc.fqn.column=fqn cache.jdbc.fqn.type=varchar(255) cache.jdbc.node.column=node cache.jdbc.node.type=blob cache.jdbc.parent.column=parent cache.jdbc.driver=org.firebirdsql.jdbc.FBDriver cache.jdbc.url=jdbc:firebirdsql:127.0.0.1/3050:pango.fdb cache.jdbc.user=sysdba cache.jdbc.password=xxx <!-- whether the cache loader writes are asynchronous --> true <!-- only one cache loader in the chain may set fetchPersistentState to true.
