[EJB 3.0] - deleting objects in a Collection based OneToMany mapping

by aberezin

I am using Jboss 4.0.4.ga and have a OneToMany like this @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "order") public Collection getLineItems() { return lineItems; } On the other side, I have this: @ManyToOne @JoinColumn(name = "order_id") public Order getOrder() { return order; } I persist an Order with one LineItem. I then clear the collection of LineItems and repersist (actually call em.merge(Object) ) the Order. Jboss doesnt appear to delete the underlying row in the LineItem table. I cant understand from the docs if the cascade = CascadeType.ALL implies that the contained objects should be deleted from the datastore when they are removed from a Collection. The docs seem to indicate this is not done for a ManyToMany bc it is not possible to know if the objects that are removed from a collection are still referenced by another entity. However, it does seem that in a OneToMany, JBOSS could know enough to delete the dependent entites from the datastore. Thanks for any help on this one.

[Beginners Corner] - ejb socket client with configurable port

by herm

An EJB connects to another system via tcp/ip. What is the best way to make the connection properties (ip, port) configurable from outside the code?

[JBoss Seam] - Re: JBoss Rules problem (where else to post?)

by dgallego

You shouldn't use an absolute path to load your rules. Instead, use this method (extracted from Drools examples and modified). | public static RuleBase readRule(Class readerClass, String rulesFile, String rulesDslFile) throws Exception | { | if (rulesFile == null) | return null; | PackageBuilder builder = new PackageBuilder(); | Reader source = new InputStreamReader(readerClass.getResourceAsStream(rulesFile)); | if (rulesDslFile == null) | builder.addPackageFromDrl(source); | else | { | Reader dsl = new InputStreamReader(readerClass.getResourceAsStream(rulesDslFile)); | builder.addPackageFromDrl(source, dsl); | } | RuleBase ruleBase = RuleBaseFactory.newRuleBase(); | Package pkg = builder.getPackage(); | ruleBase.addPackage(pkg); | return ruleBase; | } | [...] | RuleBase ruleBase = readRule(MyClass.class, "rules.drl", null); | WorkingMemory wm = ruleBase.newWorkingMemory(); | Hope it helps.

[EJB 3.0] - Re: How to know when entity is removed?

by ALRubinger

The lifecycle methods in EJB3 are defined through annotations - looks like you'd like @PostRemove. http://trailblazer.demo.jboss.com/EJB3Trail/persistence/entitylifecycle/i...

[JBoss Eclipse IDE (users)] - Re: hibernate tools hangs eclipse

by bugra

> do you have just the hibernate tools installed or also the rest of jobsside installed ? I have only hibernate tools installed. > Where you editing some xml while it were happening ? It could be possible that I had a few editor windows (tabs) open with XML files. but the "second" before the hang up of eclipse I wasn't on this editor tab. so the answer would be, I had open XML editor tabs but i was not editing them. > ... unless the jdbc driver were having a hard time to connect to the db ..could this be the case ? i don't think so. I'm currently using Apache Derby 10.1 "Nature" as a project in eclipse (starting & stopping the server from inside eclipse) - for testing purposes - and using "org.apache.derby.jdbc.ClientDriver" driver. since the DB is on the same box the connectivity shouldn't be a problem. thanks for your feedback.
