Hi *, I apologize, if this get's posted twice. My first post (through Nabble) shows up in Nabble, but I got a "You may not post" message. Anyway, I'm trying to get logback (0.9.24) to log to my Oracle Database (11g) from an Enterprise Application running on an Oracle Weblogic (11g). I'm getting the following error: 2010-09-23 11:25:34 INFO LoggerContext Could NOT find resource [logback.groovy] 2010-09-23 11:25:34 INFO LoggerContext Could NOT find resource [logback-test.xml] 2010-09-23 11:25:34 INFO LoggerContext Found resource [logback.xml] at [file:/export/home/zielk_an/workspace_produktion_trunk/trunk/base/project_base/bin/logback.xml] 2010-09-23 11:25:34 INFO ConfigurationAction debug attribute not set 2010-09-23 11:25:34 INFO AppenderAction About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender] 2010-09-23 11:25:34 INFO AppenderAction Naming appender as [STDOUT] 2010-09-23 11:25:34 INFO NestedComplexPropertyIA Assuming default type [ch.qos.logback.classic.encoder.PatternLayoutEncoder] for [encoder] property 2010-09-23 11:25:34 INFO NestedComplexPropertyIA Pushing component [encoder] on top of the object stack. 2010-09-23 11:25:34 INFO AppenderAction About to instantiate appender of type [ch.qos.logback.classic.db.DBAppender] 2010-09-23 11:25:34 INFO AppenderAction Naming appender as [DB] 2010-09-23 11:25:34 INFO NestedComplexPropertyIA Pushing component [connectionSource] on top of the object stack. 2010-09-23 11:25:34 INFO JNDIConnectionSource Driver name=Oracle JDBC driver 2010-09-23 11:25:34 INFO JNDIConnectionSource Driver version=11.1.0.7.0-Production 2010-09-23 11:25:34 INFO JNDIConnectionSource supportsGetGeneratedKeys=true 2010-09-23 11:25:34 INFO RootLoggerAction Setting level of ROOT logger to DEBUG 2010-09-23 11:25:34 INFO AppenderRefAction Attaching appender named [STDOUT] to Logger[ROOT] 2010-09-23 11:25:34 INFO AppenderRefAction Attaching appender named [DB] to Logger[ROOT] 2010-09-23 11:25:41 ERROR DBAppender problem appending event java.sql.SQLException: prepareStatement, Exception = 14 at weblogic.jdbc.wrapper.XAConnection.invocationExceptionHandler(XAConnection.java:190) at weblogic.jdbc.wrapper.XAConnection.prepareStatement(XAConnection.java:1113) at weblogic.jdbc.common.internal.ConnectionEnv.makeStatement(ConnectionEnv.java:1361) at weblogic.jdbc.common.internal.ConnectionEnv.getCachedStatement(ConnectionEnv.java:1114) at weblogic.jdbc.wrapper.Connection.prepareStatement(Connection.java:793) at ch.qos.logback.core.db.DBAppenderBase.append(DBAppenderBase.java:99) at ch.qos.logback.core.UnsynchronizedAppenderBase.doAppend(UnsynchronizedAppenderBase.java:91) at ch.qos.logback.core.spi.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:64) at ch.qos.logback.classic.Logger.appendLoopOnAppenders(Logger.java:283) at ch.qos.logback.classic.Logger.callAppenders(Logger.java:270) at ch.qos.logback.classic.Logger.buildLoggingEventAndAppend(Logger.java:471) at ch.qos.logback.classic.Logger.filterAndLog_0_Or3Plus(Logger.java:425) at ch.qos.logback.classic.Logger.info(Logger.java:629) Has anyone experienced similar problems?
