Hi All, I'm trying to integrate a Drools Guvnor application to an existing project. My problem is in the repository.xml file (and Jackrabbit jndi lookup, I think) - I'm trying to get an existing datasource. It is successfully deployed and all the other applications can use it to access the DB. I'm using the following configuration to get the datasource: Of course the file contains much more config tags and if necessary, I'll give them. And the exception from the JBoss console is: 18:39:39,713 INFO [STDOUT] ERROR 23-10 18:39:39,713 (DatabaseFileSystem.java:init:195) failed to initialize file system java.sql.SQLException: No suitable driver at java.sql.DriverManager.getConnection(DriverManager.java:545) at java.sql.DriverManager.getConnection(DriverManager.java:171) at org.apache.jackrabbit.core.fs.db.DbFileSystem.getConnection(DbFileSystem.java:187) at org.apache.jackrabbit.core.fs.db.DatabaseFileSystem.initConnection(DatabaseFileSystem.java:956) at org.apache.jackrabbit.core.fs.db.DatabaseFileSystem.init(DatabaseFileSystem.java:175) at org.apache.jackrabbit.core.config.FileSystemConfig.createFileSystem(FileSystemConfig.java:47) at org.apache.jackrabbit.core.RepositoryImpl.(RepositoryImpl.java:244) at org.apache.jackrabbit.core.RepositoryImpl.create(RepositoryImpl.java:557) at org.apache.jackrabbit.core.TransientRepository$2.getRepository(TransientRepository.java:245) at org.apache.jackrabbit.core.TransientRepository.startRepository(TransientRepository.java:265) at org.apache.jackrabbit.core.TransientRepository.login(TransientRepository.java:333) at org.apache.jackrabbit.core.TransientRepository.login(TransientRepository.java:363) at org.drools.guvnor.server.repository.RepositoryStartupService.newSession(RepositoryStartupService.java:135) at org.drools.guvnor.server.repository.RepositoryStartupService.create(RepositoryStartupService.java:56) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ... 18:39:39,932 INFO [STDOUT] ERROR 23-10 18:39:39,932 (RepositoryImpl.java::343) failed to start Repository: File system initializat ion failure.: failed to initialize file system org.apache.jackrabbit.core.config.ConfigurationException: File system initialization failure.: failed to initialize file system: failed to i nitialize file system at org.apache.jackrabbit.core.config.FileSystemConfig.createFileSystem(FileSystemConfig.java:54) at org.apache.jackrabbit.core.RepositoryImpl.(RepositoryImpl.java:244) at org.apache.jackrabbit.core.RepositoryImpl.create(RepositoryImpl.java:557) at org.apache.jackrabbit.core.TransientRepository$2.getRepository(TransientRepository.java:245) at org.apache.jackrabbit.core.TransientRepository.startRepository(TransientRepository.java:265) at org.apache.jackrabbit.core.TransientRepository.login(TransientRepository.java:333) at org.apache.jackrabbit.core.TransientRepository.login(TransientRepository.java:363) at org.drools.guvnor.server.repository.RepositoryStartupService.newSession(RepositoryStartupService.java:135) at org.drools.guvnor.server.repository.RepositoryStartupService.create(RepositoryStartupService.java:56) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.seam.util.Reflections.invoke(Reflections.java:22) at org.jboss.seam.intercept.RootInvocationContext.proceed(RootInvocationContext.java:31) at org.jboss.seam.intercept.SeamInvocationContext.proceed(SeamInvocationContext.java:56) I tried to migrate to jackrabbit 1.5, but there was no change in the deployment exceptions. Please, ANY ideas are welcome.
