我與EJB3 Java中大型企業應用程序的工作。異常：javax.resource.spi.ResourceAdapterInternalException：意外的錯誤
我正在從數據庫查詢以下> SELECT含量TBLMXML幫助XML內容。 並獲得該內容與下面的代碼幫助：
if(rowSet.getObject("CONTENT") instanceof oracle.sql.OPAQUE){
XMLType xmlType = XMLType.createXML(((oracle.sql.OPAQUE) rowSet.getObject("CONTENT"));
}
但是，當此查詢解僱我收到以下錯誤：
14:21:15,698 : [WARN ] : [TxConnectionManager] : Connection error occured: org.jboss.resource.[email protected]1357dfa[state=NORMAL [email protected]1897e13 handles=1 lastUse=1336294101874 permit=true trackByTx=true mcp=org.jbos[email protected]9f08ca context=org[email protected]fa3d7c xaResource=org.jboss[email protected]191a3ed txSync=null]

在此先感謝
