[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2602) Document use of flat dataset file in the Seam reference

[ http://jira.jboss.com/jira/browse/JBSEAM-2602?page=comments#action_12399058 ] Siarhei Dudzin commented on JBSEAM-2602: ---------------------------------------- Ok, I think I might know where the default format as 'flat' is coming from in Seam. As you already know dbunit supports two data formats: flat and xml (actually flat is also an xml-like format but it's somewhat closer to insert statements and also more compact). Apparently when performing data export with *ant tasks* it uses "flat" format as default (which is I guess why flat format was chosen for Seam). See section "Parameters specified as nested elements" at http://www.dbunit.org/anttask.html At the same time there is a maven2 plugin, which also can perform export but for some reason the default format is "xml": http://mojo.codehaus.org/dbunit-maven-plugin/export-mojo.html#format While Seam reference does not specify in which format the mock data should be used I (naively) used the default format my build system used (Maven 2). Further, when trying to use this exported file in Seam Integration Tests (just as specified in the examples) DbUnit was just throwing "NoSuchTableException: null" without a word on wrong data format. org.jboss.seam.mock.DBUnitSeamTest uses FlatXmlDataSet in "public DataSetOperation(String dataSetLocation, DatabaseOperation operation)". DbUnit itself also isn't doing much error handling and simply throws "NoSuchTableException: null" if 'xml' data format is fed to FlatXmlDataSet. As soon as I changed format to flat the problem was gone. While I am not going to argue which format is better as a default (actually flat looks more compact) I thought it may be a good idea at least to mention in the reference which data format should be used or even allow usage of both formats. Pete, is this enough for the reference or did you mean something else? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
