Re: GORM outside Grails

i've been playing around with this code for a couple of days now trying to get it to work in a self-contained jar file (since i eventually want to use the code to access gorm from java) - the problem i run into is that the dynamic gorm 'save()' method isn't found at runtime (see stack trace below) - the problem disappears if i include the 'grails-app' directory containing the domain class definitions in the same directory as the jar file containing the compiled class files

my jar file ('beckwith.jar') includes all the class files generated by 'grails compile' as well as the 'grails-app' directory contents and the 'application.properties' file - at the moment i have to include the file 'scripts/Main.groovy' in the same directory as the jar file until i figure out how to load it as a resource from the jar file

here's the command i'm using to run the program

java -classpath beckwith.jar:$GRAILS_HOME/lib/groovy-all-1.5.6.jar:$GRAILS_HOME/lib/spring-2.5.4.jar:$GRAILS_HOME/lib/commons-logging-1.1.jar:$GRAILS_HOME/dist/grails-core-1.0.3.jar:$GRAILS_HOME/lib/javaee.jar:$GRAILS_HOME/dist/grails-spring-1.0.3.jar:$GRAILS_HOME/dist/grails-gorm-1.0.3.jar:$GRAILS_HOME/lib/hibernate-annotations.jar:$GRAILS_HOME/lib/hibernate3.jar:$GRAILS_HOME/lib/dom4j-1.6.1.jar:$GRAILS_HOME/lib/hibernate-commons-annotations.jar:.:$GRAILS_HOME/lib/commons-lang-2.1.jar:$GRAILS_HOME/lib/commons-collections-3.2.jar:lib/mysql-connector-java-5.0.8-bin.jar:$GRAILS_HOME/lib/cglib-nodep-2.1_3.jar Tester

here's the exception i get - any idea how to get around this?

Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: com.burtbeckwith.gorm.domain.Book.save() is applicable for argument types: () values: {}
