Hello, i’m having problems running liquibase (2.0.5) inside websphere ce 3 Liquibase is wrapt inside an @Singleton @Startup EJB and liquibase is called inside the @PostConstruct Method With the Thread.currentThread().getContextClassLoader() classloader, and a JdbcConnection optained by an injected @Resource DataSource datasource. [datasource.getConnection()] This works fine in JBoss6/7 and Weblogic 12c. But with websphere ce 3 i’m getting following stacktrace, 1. Caused by: de.company.core.exception.LiquibaseUpdateException[\_Pzc3MFsYEe6LG6biO6Txsw]: Unable to update/verifiy database         at de.company.core.persistence.LiquibaseUpdateBean.update(LiquibaseUpdateBean.java:145)         at de.company.cmsservice.logic.CmsServiceStartupBean.startup(CmsServiceStartupBean.java:36)         … 58 more Caused by: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger         at liquibase.logging.LogFactory.getLogger(LogFactory.java:19)         at liquibase.logging.LogFactory.getLogger(LogFactory.java:30)         at liquibase.database.DatabaseFactory.findCorrectDatabaseImplementation(DatabaseFactory.java:67)         at de.company.core.persistence.LiquibaseUpdateBean.doUpdate(LiquibaseUpdateBean.java:100)         at de.company.core.persistence.LiquibaseUpdateBean.update(LiquibaseUpdateBean.java:137)         … 59 more Caused by: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger         at liquibase.servicelocator.ServiceLocator.newInstance(ServiceLocator.java:179)         at liquibase.logging.LogFactory.getLogger(LogFactory.java:17)         … 63 more Caused by: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger         at liquibase.servicelocator.ServiceLocator.findClass(ServiceLocator.java:145)         at liquibase.servicelocator.ServiceLocator.newInstance(ServiceLocator.java:177)         … 64 more so it might be related to [https://liquibase.jira.com/browse/CORE-789](https://liquibase.jira.com/browse/CORE-789) any hints where i could find the error in my setup would be a appreciated. regards, frank ---

I’m having exactly the same problem. I run liquibase from code with something like (Scala): 1. val database = DatabaseFactory.getInstance.findCorrectDatabaseImplementation(new JdbcConnection(dbConnection)) 2.     val classLoader = classOf[SchemaMigration].getClassLoader 3.     val resourceAccessor = new ClassLoaderResourceAccessor(classLoader) 4.     val liquibase = new Liquibase(diffFilePath, resourceAccessor, database) 5. … 6. liquibase.update(null) It works fine in Jetty and Tomcat, but when I run it in a standalone app it fails with the same exception as above. I have Scala applications that use Liquibase and they have loggers available and working fine (logback, slf4j). Not sure what to do. ---

Maybe there are better ways to run Liquibase from code? I didn’t find any higher level APIs. ---

I tried with 2.0.5 and 3.0.5 Liquibase versions ---

That should be the best way to call liquibase through the java APIs. Could you post the stacktrace you are seeing with 3.0.5?  Nathan ---

Hi Nathan, thanks for looking into it. Here is the stacktrace: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger     at liquibase.logging.LogFactory.getLogger(LogFactory.java:19)     at liquibase.logging.LogFactory.getLogger(LogFactory.java:30)     at liquibase.database.DatabaseFactory.findCorrectDatabaseImplementation(DatabaseFactory.java:71)     at com.mycompany.db.migration.SchemaMigration.createLiquibase(SchemaMigration.scala:27)     at com.mycompany.db.migration.SchemaMigration.updateDb(SchemaMigration.scala:35)     at com.mycompany.db.migration.SchemaMigration.run(SchemaMigration.scala:55)     at com.mycompany.server.JobServerRunner.init(JobServerRunner.scala:49)     at com.mycompany.server.JobServerRunner$.startup(JobServerRunner.scala:67)     at com.mycompany.server.JobServerRunner$.main(JobServerRunner.scala:79)     at com.mycompany.server.JobServerRunner.main(JobServerRunner.scala)     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)     at java.lang.reflect.Method.invoke(Method.java:606)     at com.simontuffs.onejar.Boot.run(Boot.java:340)     at com.simontuffs.onejar.Boot.main(Boot.java:166) Caused by: liquibase.exception.ServiceNotFoundException: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger     at liquibase.servicelocator.ServiceLocator.newInstance(ServiceLocator.java:188)     at liquibase.logging.LogFactory.getLogger(LogFactory.java:17)     … 15 more Caused by: liquibase.exception.ServiceNotFoundException: Could not find implementation of liquibase.logging.Logger     at liquibase.servicelocator.ServiceLocator.findClass(ServiceLocator.java:154)     at liquibase.servicelocator.ServiceLocator.newInstance(ServiceLocator.java:186)     … 16 more So this is a regular jar file (packaged with one-jar). Please let me know if I can do any tests to help clarify this issue. Thanks ---

Nathan, if it helps, I can create a small project (Scala/jar) that reproduces this issue and put it on github for you to look at. Let me know if that could be useful to you. Thanks ---

It is still working fine for me. If you could create a jar that reproduces it that would be great. You can put it on github, attach it here or email it to me ([nathan.voxland@liquibase.org](mailto:nathan.voxland@liquibase.org)) Thanks, Nathan ---

Thanks, Nathan Will make a jar tomorrow
