[JBoss Seam] - Re: Enum as a Seam component

by pete.muir＠jboss.org

You can't instantiate enums so they can't be Seam components. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071143#4071143 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4071143

[JBoss Seam] - Enum as a Seam component

by ellenzhao

My user is supposed to specify importances of something from the UI. The importance are interpreted as Shorts. Here is my Enum: | @Name("importance") | @Scope(APPLICATION) | public enum Importance{ | DONT_CARE((short) 0, "I don't care"), NOT_VERY((short) 1, | "Not very important"), DONT_KNOW((short) 2, "I don't know"), IMPORTANT( | (short) 3, "Important"), VERY((short) 4, "Very important"); | | private final Short weight; | private final String label; | | Importance(Short weight, String label){ | this.weight = weight; | this.label = label; | } | | public Short getWeight(){ | return this.weight; | } | | public String toString(){ | return this.label; | } | } | I put it into the entity package since semantically it's closer to entities. The client code in the controller package is: | short impor = Importance.DONT_KNOW.getWeight(); | this.foo.setDistanceImportance(impor); | this.foo.setFondnessImportance(impor); | ... | However I got

[Installation, Configuration & DEPLOYMENT] - Re: Update to jdk 1.5.0_12 causes package does not exists in

by shausch

First of all: on windows you have to restart the system after changing the environment variables (like JAVA_HOME, CLASSPATH,...). ;-) To ensure having a clean new build I deleted /work and /tmp of JBoss-server. After each reboot I rebuild and redeployed the whole project. So far I can say: _06 is working. _10 and _12 don't. I didn't test more jdk-versions. It's stupid. So be aware of the risks of changing jdk-versions without any tangible need. Never change a running system.

[JBoss Seam] - Hotel bookinkg sample does not work properly

by fredatwork

Hello, I'm a newbee to seam. I'm building my first app using the good ideas from the seam samples delivered with seam 2.0 (beta). More specificaly, I'm trying to build a new long-running conversation, based on the the hotel booking sample. However, this sample does not work properly. I deploy the sample on my JBoss 4.2.1 server without any error. But when I start the long running conversation by clicking on the 'View hotel' link, nothing happens. Could anyone let me know what is wrong with the hotel booking sample. since the problem happens exactly where the long-running conversation is started with the @Begin annotation ? <s:link id="viewHotel" value="View Hotel" action="#{hotelBooking.selectHotel(hot)}"/> I have the same behaviour with my own trial; no wonder, since I'm using the hotel booking app as a start-up sample.... Thanks in advance for any help on this matter.

[JBoss Seam] - Re: JBoss 4.2.1GA and Hibernate validator - broken

by pete.muir＠jboss.org

Sure, no hibernate stuff from Seam is packaged in as runtime dependencies, but, for the examples at least, the hibernate-all.jar *is* used to compile the example (and hence the @Min annotation). The api for @Min has changed between the version of hibernate-all (not sure what this is btw) we have and the hibernate in the AS. I was able to fix it by removing hibernate-all.jar and adding the hibernate/lib to the compile classpath.

[JBoss Seam] - Re: JBoss 4.2.1GA and Hibernate validator - broken

by wschwendt

Thanks for your reply, Pete. I forgot to mention that I'm using the CVS based Seam 2. When building the Seam example such as the hotel booking example, by default no Hibernate jars are packaged. Rather, the Hibernate jars shipped with JBoss AS are used (I'm using JBoss 4.2.1GA). I looked at the hibernate/lib directory of the CVS based Seam: It includes Hibernate 3.2.1.ga, Hibernate Annotations 3.2.1.GA and Hibernate EntityManager Version: 3.2.1.GA. Thus, only the Hibernate version is more recent than the one shipped with JBoss 4.2.1GA, but the Hibernate Annotations and Hibernate EntityManager are the same as shipped with JBoss 4.2.1GA. While there are more recent versions available (Hibernate EntityManager 3.3.1GA and Hibernate Annotations 3.3.0GA, with Hibernate validator now separate in Hibernate validador 3.3.0GA.jar), these are not included in the Seam based CVS. I also forgot to mention that only the @Min Hibernate validator failed. The @NotNull validator and other validators such as @Length are working fine.
