Utilizzando il connection pool di tomcat via app attrraverso ibatis/mybatis alcune chiamate a Store Procedure Oracle generavano errore
Caused by: java.lang.RuntimeException: unexpected invocation exception: unexpected invocation exception: null at oracle.ucp.jdbc.proxy.PreparedStatementProxyFactory.invoke(PreparedStatementProxyFactory.java:138) at oracle.ucp.jdbc.proxy.CallableStatementProxyFactory.invoke(CallableStatementProxyFactory.java:101) at $Proxy17.getResultSet(Unknown Source) at com.ibatis.sqlmap.engine.execution.SqlExecutor.getFirstResultSet(SqlExecutor.java:337) at com.ibatis.sqlmap.engine.execution.SqlExecutor.handleMultipleResults(SqlExecutor.java:299) at com.ibatis.sqlmap.engine.execution.SqlExecutor.executeQueryProcedure(SqlExecutor.java:283) at com.ibatis.sqlmap.engine.mapping.statement.ProcedureStatement.sqlExecuteQuery(ProcedureStatement.java:34) at com.ibatis.sqlmap.engine.mapping.statement.GeneralStatement.executeQueryWithCallback(GeneralStatement.java:173)
La soluzione è semplicemente NON chiamare le procedure con ibatis.callProcedure() ma con ibatis.update()
