I have a problem with my application running in jboss 4.2.2. I recive randomly the following error: java.sql.SQLException: The result set is closed. | at org.jboss.resource.adapter.jdbc.WrappedResultSet.checkState(WrappedResultSet.java:1939) | at org.jboss.resource.adapter.jdbc.WrappedResultSet.next(WrappedResultSet.java:1181) while processing a resultset in a stateless session bean. The bean is invoked by a web layer not directly, but through a session facade. I can reproduce this error running a test application made with Selenium. This test case reproduce several time the same user navigation flow. The test case uses few stateless session bean: everyone makes a query to the db using stored procedures. The error occurs not in the same piece of code everytime, but in different db call. Every call to ejb layer is synchronized. I check that every connections is closed after the use. Checking the connection pool i verified that only one connection is used. Follows the datasource definition. <local-tx-datasource> | <jndi-name>myDS</jndi-name> | <connection-url>jdbc:microsoft:sqlserver://dbserver:1433;SelectMethod=cursor;DatabaseName=myDBSchema</connection-url> | <driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class> | <user-name>user</user-name> | <password>password</password> | <!-- sql to call when connection is created | <new-connection-sql>some arbitrary sql</new-connection-sql> | --> | <min-pool-size>1</min-pool-size> | <max-pool-size>10</max-pool-size> | <idle-timeout-minutes>15</idle-timeout-minutes> | <blocking-timeout-millis>5000</blocking-timeout-millis> | | <!-- sql to call on an existing pooled connection when it is obtained from pool | <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql> | --> | | <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> | <metadata> | <type-mapping>MS SQLSERVER2000</type-mapping> | </metadata> | </local-tx-datasource> This error occurs using also Sql Server 2005.
