Hi Christine I'm not totally sure from your example that betwixt was or wasn't using the .betwixt file. You could turn on commons-logging to debug and you'll see what .betwixt files it loads. If you don't have log4j or logkit on your classpath and are not on JDK1.4 then there's a description of how to do this here...
http://nagoya.apache.org/gump/javadoc/jakarta-commons/logging/dist/docs/api/ org/apache/commons/logging/impl/SimpleLog.html Also you could try the following .betwixt file, which will use attributes for all properties of your Knowledge object <?xml version="1.0" encoding="UTF-8" ?> <info primitiveTypes="element"> <element name="KnowledgeObject"> <addDefaults/> </info> James ----- Original Message ----- From: "Christine Keim" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, June 13, 2002 11:30 PM Subject: Torque OM Betwixt and general use Hello, since there is no commons-user-List, i'll try my luck here. I am using Turbine along with Torque as an OM-Tool. Some data of an object generated with Torque should be stored in a XML-DB (Xindice, to be ecaxt). Now i thought i might use betwixt to map the wanted attributes to a nice XML and put it in the DB. Now i first wanted to look at the example of betwixt, for some reason i can't (ant failes the build cause it doesn't find org.apache.commons.betwixt.strategy.NameMapper, which is in the source-directory, but not in the jar - why's that? ). Well, after that i tried to figure it out, and i now have a prettyprinted XML from the OM-Class, though there's all attributes in it. Probably i'm using it all wrong, but the documentation is rather short, so i ought someone here could provide me with some insight ^^ (pretty please) my OM-Class is named KnowledgeObject and to test it i want to generate an xml just with the subject and description attribute in it. I made a KnowledgeObject.betwixt-File which looks this way: <?xml version="1.0" encoding="UTF-8" ?> <KnowledgeObject primitiveTypes="attribute"> <element name="subject" property="subject"/> <element name="description" property="description"/> </<KnowledgeObject > and i put that in the class-directory, actually exaclty in the directory the om-Class also is (KnowledgeObject.class) In the Class KnowledgeObjectPeer i made a new method which should also create the xml from the OM-Class. public static ObjectKey doInsert(Criteria criteria, KnowledgeObject ko) throws Exception { // insert the data in the relational DB ObjectKey result = BaseKnowledgeObjectPeer.doInsert(criteria); ko.setPrimaryKey(result); // Use Betwixt to create an XML file from the Knowledge Object BeanWriter beanWriter = new BeanWriter(System.out); beanWriter.enablePrettyPrint(); beanWriter.write(ko); } // doInsert Now this produces some nice looking XML, though i only want something like this to be created (and i thought with the betwixt-file i ruled it). <KnowledgeObject id="2"> <subject>Subject</subject> <description>Description</description> </KnowledgeObject How do i tell the BeanWriter to use the betwixt-file? There is no error thrown, so i think it doesn't use the betwixt file at all ... ^^;; tia, Christine Keim _________________________________________________________ Do You Yahoo!?
