[JBoss Seam] - Re: Any way to debug why Seam isn't registering a component?

by SmokingAPipe

I got it working, using: http://chiralsoftware.com/blog/PropertyNotFoundException-Target-Unreachab... blog entry Conclusion: Wrong seam jar file in WEB-INF/lib. I'm not sure how that prevented the ejbs from being installed, but it did. Debugging was by tediously going over exploded archives, modifying until it worked. I hope this helps someone else.

Do you have a jndi.properties in the classpath of your client application (the HelloTestRemote client). I believe, you do have one. What are its contents?

[JBoss Seam] - Re: Seam on OAS

by michael.yuan＠jboss.com

OC4J 11 supports EJB3. So, you can use EJB3 beans with Seam if you deploy there. See the examples/jee5 example for more details. If you are stuck with J2EE 1.4 version of OC4J, you cannot use EJB3 session beans. Instead, you use POJOs with Seam managed transactions. They are really the same as EJB3 session beans except that they do not require EJB3 annotations (e.g., @Stateful and @Remove) and do not require interfaces. So, they are simpler than EJB3 session beans. See the examples/jpa example to see how Seam POJO + JPA is used in J2EE application servers.

[JBoss Seam] - [Bug?] noSelectionLabel, <s:selectItems>, equals()

by fmars

Hi, After i added noSelecteionLabel to my <s:selectItems>, i got a NullPointerException in my entity's equals method, because the parameter was null. if noSelectionLabel is selected, the equals method of the entity is called and because "Please select ..." doesn't exists, it sent as null object. My suggestion: if noSelectionLabel is selected, then we don't need to call equals() method anymore. Am i right?

[JBoss Seam] - Seam on OAS

by omilian3

The Seam homepage states: "you can use Seam in any J2EE application server, with one caveat: you will not be able to use EJB 3.0 session beans. However, you can use either Hibernate or JPA for persistence, and you can use Seam JavaBean components instead of session beans" (http://labs.jboss.com/jbossseam/faq#j2ee) Does this mean that if I were to deploy Seam on Oracle App Server (OAS) then I would not be able to use Session Beans at all? Maybe I can use EJB 2.1 Session Beans? If Session Beans can't be used, then how should transactions be handled? Lastly, if anyone has actually deployed Seam on OAS I would be very interested to hear of your experiences. Alex.

[EJB 3.0] - Re: Invalid invocation of local interface (null container)

by jaikiran

You are trying to lookup a local bean interface from the standalone client (remote client). Local interfaces are not meant for that. Local interfaces can be used when the client is part of the same JVM as the application server. Lookup the remote interface instead of the local interface from your main() method: HelloRemote helloR = (HelloRemote) ctx.lookup("HelloBean/remote"); | if (helloR == null) { | System.out.println("Hello is null"); | } | System.out.println("Output = " + helloR.hello()); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067627#4067627 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4067627
