[EJB 3.0] - Automatically create schema in database

by hamtho2

Hi, is there any chance to let the EntityManager automatically create a schema? I defined a default schema for my entities through setting the property 'hibernate.default_schema' in the persistence.xml, but unfortunately it is only possible to deploy these entities, if the schema already exists in the database. I thought of something equal as it is already possible for automatic creation of database-tables for the entities if the property 'hibernate.hbm2ddl.auto' has been defined to 'create'. Thanks for your help Thomas View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4120317#4120317 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4120317

[EJB 3.0] - Re: Update exiting BLOB does not work

by CarstenRudat

Hi all, I have tested this with Hibernate directly. a) If I set the blob while my entity (Signature) is attached to a EntityManager-Session, my new blob will be updated to the database b) If I set the blob while it is not attached, then reattache to a new session and calling a EntityManager.merge(signature) the blob will not be updatet to the database. Is a) the only way to update a blob? If I create a new Signature with a Blob (not attached) and call EntityManager.perist(signature), my blob will also be inserted. So, why does update causes these problems?

[Javassist user questions] - know who has the monitor on an object

by cat4hire

Hi, is it possible using Javassist to understand if a specified instance has a monitor active? I know this is not a problem of reflection, but given an instance CI of class C, if I need to load a modified version of class C to produce CI2 that substitutes CI I should bother with any possible thread blocked on CI. Any idea on this?

[JBoss jBPM] - Re: task in start state

by debnathm

Hi I have the following state definition (fragment): <process-definition> | <start-state name='start'> | <task name='StartStateTask'> | <controller> | <variable access='read,write,required' name='variable1' mapped-name='Var1'></variable> | </controller> | </task> | <transition to='task-node1' name='to_task_node1'></transition> | </start-state> | ... I use the following code to create a process Instance: ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( <xml string above>); ProcessInstance processInstance = new ProcessInstance(processDefinition); Later, I call the following code: TaskMgmtInstance taskmgmtInstance = processInstance.getTaskMgmtInstance(); Token token = processInstance.getRootToken(); if (taskmgmtInstance.hasUnfinishedTasks(token) == false) { ... } else { ... } However, even though the start state has a task, it seems to enter the "if" block, not the "else" part. Any suggestions would be appreciated.

[JBoss Tools (users)] - model -> action dependencies in seam module

by nickarls

Hi, Taking my complaints to new ground ;-) http://www.jboss.com/index.html?module=bb&op=viewtopic&t=127566 I think the "no model -> action dependencies" in new seam web projects might be a little confusing for some (hoping that it's not only me) since adding a reference from an entity to an action results in a NoClassDefFoundError at deploy time. Now with DDD being hip and all, it would be nice to be able to put business logic into the domain objects. I wouldn't mind if it would only be the actions that would be hot-deployable as long as the project would be deployable at all...

[JBossWS] - WebContext annotation and contextRoot

by fbenvegna

I have a web-service (Session EJB3 as WS) within web application named 'wmi'. My web context root is 'wmi'. The original wsdl url is http://host:port/wmi-wmi/beanClassName?wsdl. I want wsdl url as http://host:port/wmi/services?wsdl The problem is that when I set @WebContext(contextRoot = "/wmi" , urlPattern="/services") on EJB3, url http::/wmi/services?wsdl return 404 (page not found). But set @WebContext(contextRoot = "/wmi-ws" , urlPattern="/services") works fine (http://host:port/wmi-ws/services?wsdl).

It's probably my Eclipse configuration. I stopped trying to use a real database (for testing) and now use a HSQLDB. Works fine for me...
