- JBoss 4.2.0GA Hello, everybody! I'm having problems with the <jar-file> element of my persistence deployment descriptor (persistence.xml). I have deployed my EJB jar file to the directory C:\jboss-4.2.0.GA\server\default\deploy and I have placed a jar file that also has entity beans to be analysed in the directory C:\jboss-4.2.0.GA\server\default\lib. This file is referenced in the persitence.xml file. But the problem is that I keep getting error messages when I'm deploying my EJB jar file to the directory deploy. The persistence provider can't find the jar file specified in the <jar-file> element. This was my persistence.xml file the first time I tested it: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="laboratorio-informatica"> <jta-data-source>java:/LaboratorioInformaticaDS</jta-data-source> <mapping-file>META-INF/orm.xml</mapping-file> <jar-file>urca.jar</jar-file> </persistence-unit> and I got this error message when deploying: java.lang.RuntimeException: error trying to scan <jar-file>: file:/C:/jboss-4.2.0.GA/bin/urca.jar So, I kept modifying the <jar-file> element and got these results: <jar-file>lib/urca.jar</jar-file> java.lang.RuntimeException: error trying to scan <jar-file>: file:/C:/jboss-4.2.0.GA/bin/lib/urca.jar <jar-file>/lib/urca.jar</jar-file> java.lang.RuntimeException: error trying to scan <jar-file>: file:/C:/lib/urca.jar <jar-file>../lib/urca.jar</jar-file> java.lang.RuntimeException: error trying to scan <jar-file>: file:/C:/jboss-4.2.0.GA/server/default/deploy/lib/urca.jar <jar-file>../server/default/lib/urca.jar</jar-file> java.lang.RuntimeException: error trying to scan <jar-file>: file:/C:/jboss-4.2.0.GA/server/default/deploy/server/default/lib/urca.jar So, I couldn't in any way tell the persistence provider to look the file at the directory C:\jboss-4.2.0.GA\server\default\lib. Please, what do I have to specify in the <jar-file> element to solve this problem? Thank you. Marcos View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058118#...
