[Persistence, JBoss/CMP, Hibernate, Database] - NULL FOREIGN KEY

by pvelarde

Hi all, I've got a master-detail relation mapped with these two simple EJB3.0 beans below; when I modify master record, the detail records lose the join with master so masterid is set to null in detail table. I don't want any cascade efect so CASCADETYPE is not established in master. I've read something about this problem in forus but have no solution. Is this an Hibernate bug¿? have any idea ¿? thanks for your help. MASTER BEAN CODE @Entity | @Table(name = "master") | @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) | public class MasterEJB implements Serializable { | | ... | | protected Collection<DetailEJB> details = new Vector<DetailEJB>(); | | @OneToMany(targetEntity = DetailEJB.class) | @JoinColumn(name="master_id") | public Collection<DetailEJB> getDetails() { | return details; | } | | public void setDetails(Collection<DetailEJB> details) { | this.details = details; | } | | ... | DETAIL BEAN CODE @Entity | @Table(name = "detail") | @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) | public class DetailEJB implements Serializable { | | ... | | @ManyToOne(optional=false) | @JoinColumn(name="master_id", nullable=false) | public Integer getMasterID() { | return masterid; | } | | public void setMasterID(Integer masterid) { | this.masterid = masterid; | } | | ... | Each bean has its own table on a MySQL DBMS, here are master and detail tables definitions: CREATE TABLE `master` ( | `id` int(11) NOT NULL auto_increment, | PRIMARY KEY (`id`) | ) ENGINE=InnoDB | | CREATE TABLE `detail` ( | `id` int(11) NOT NULL auto_increment, | `master_id` int(11) default '0', | PRIMARY KEY (`id`), | KEY `FK30E0AFBF496DF04C` (`master_id`) | ) ENGINE=InnoDB | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092982#4092982 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4092982

[EJB/JBoss] - ejbFindByPrimaryKey not calling when we perform the action o

by akm115

Hi, We are using the EJB1.1 When we perform Edit Action on a record, we are getting the data by using ejbFindByPrimaryKey & getter on ejb. (BMP EntityBean) in ejbFindByPrimaryKey, we are calling the load() to load all the details. in the getter method we are just returning the already loaded details. If we again perform the same Edit Action then ejbFindByPrimaryKey not calling. But correct data is coming. i thought JBOSS internally maintaing the data in cache. Where can i modify/change the property for every time to call EJB Find by Primary Key? We are using the JBOSS 4.0.5 Thanks in advance Krishna Mohan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092979#4092979 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4092979

[Clustering/JBoss] - Re: NameNotFound Exception on switching over

by bstansberry＠jboss.com

For the service you listed it's the deploy/cluster-service.xml file "jboss:service=${jboss.partition.name:DefaultPartition}" mbean, "StateTransferTimeout" attribute. If increasing the timeout doesn't work, have a look at the logs on the coordinator node (the one providing state) to see if they show anything.

[JBoss jBPM] - Delegation Class Problems (Repost)

by Tom Brough

I have desgined a very small workflow using eclipse. I have incorporated an assignment class to delegate a task to a particular user. All micky mouse stuff but I am getting the following in JBOSS log ERROR [Delegation] couldn't load delegation class '' and this from the web page :- Error starting process: An exception of type "org.jbpm.graph.def.DelegationException" was thrown. Now this is my processdefinition.xml | <?xml version="1.0" encoding="UTF-8"?> | | <process-definition | xmlns="urn:jbpm.org:jpdl-3.2" | name="IT01"> | <swimlane name="initiator"> | <assignment class=""></assignment> | </swimlane> | <swimlane name="ITManager"> | <assignment class=""></assignment> | </swimlane> | <start-state name="start"> | <transition name="transition1" to="getDetails"></transition> | </start-state> | <end-state name="end"></end-state> | <task-node name="getDetails"> | <task name="getDetails" swimlane="initiator"></task> | <transition name="Transition2" to="Check Form"> | </transition> | </task-node> | <task-node name="Check Form"> | <task name="ITManagerFormCheck"> | <assignment class="uk.gov.torbay.it01.jbpm.ITManagerAssignment"> | <actor>manager</actor> | </assignment> | </task> | <transition name="Transition3" to="end"></transition> | </task-node> | </process-definition> and this is the source of my uk.gov.torbay.it01.jbpm.ITManager Assignment class. | package uk.gov.torbay.it01.jbpm; | | import org.jbpm.graph.exe.*; | import org.jbpm.taskmgmt.def.*; | import org.jbpm.taskmgmt.exe.Assignable; | | public class ITManagerAssignment implements AssignmentHandler { | | private static final long serialVersionUID = 1L; | | private String actor; | | public ITManagerAssignment() | { | } | public void assign(Assignable assignable, ExecutionContext executionContext) { | assignable.setActorId("manager"); | } | public String getActor() { | return actor; | } | public void setActor(String actor) { | this.actor = actor; | } | | } | >From the above error It would appear I have a parsing problem with the processdefinition.xml file since it seems to be trying to load a null class path/name. Anyone got any ideas where I am going wrong here ? The Eclipse deploy seems to indicate everything is ok so I am not sure whate to believe here. Appologies for repost I quoted the code instead of coding it and it didnt like it, price you pay for not previewing things in the first place. Tom.

[JBoss Seam] - Re: Mapping exception

by pete.muir＠jboss.org

No, I think you have a problem with your mappings - are you *sure* that class is mapped as an entity? Check in the entity mappings at startup and post code!
