[Design the new POJO MicroContainer] - Changing jboss-test dependency

by pgier

To follow the maven conventions, I'm changing the groupId of the dependency on jboss-test from "jboss" to "org.jboss". If you have any problems with this, just let me know. I'm also removing the call to the jboss-retro plugin temporarily. I will be replacing it with an updated version soon.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: JBAS-3532 Design

by JerryGauth

Brian - I'm documenting my progress here as I'll be away on vacation when you return. The required dependencies are as follows. The dependency states are reversed from your example. | <bean name="DistributedReplicantManager" ... | <property name="HAPartition"><inject bean="HAPartition" state="Create"/></property> | <depends>HAPartition</depends> | </bean> | | <bean name="HAPartition" ... | <property name="distributedReplicantManager"><inject bean="DistributedReplicantManager" state="Instantiated"/></property> | </bean> | I've checked in the changes necessary to provide dependency injection and I've removed the logic that supported usage of ClusterPartition without DI of DRM (as it appears that was your intent). This implementation differs from DI of DistributedState where DS was injected into ClusterPartitionConfig which was then passed into the ClusterPartition constructor. My implementation injects DRM directly into ClusterPartition as I couldn't resolve the circular dependencies between DRM and ClusterPartition when injecting into the Config object. I'm going to revisit this as I may have missed something when trying it earlier.

[Design the new POJO MicroContainer] - Re: PropertyInfo type creation

by scott.stark＠jboss.org

We should be restrictive on the type so if the setter is more specific use that. If its parameterized you have to assume somewhere SimpleBean bean = beans.get(0) is being used, and allowing a list for which this would not work would cause a CCE.

[Design the new POJO MicroContainer] - PropertyInfo type creation

by alesj

I stumbled upon this issue when testing CallbackItems: The getter returns non-generic List type (ReflectClassInfoImpl), but the setter has generic parameter (ParameterizedClassInfo). | public List getBeans() | { | return beans; | } | | public void setBeans(List<SimpleBean> beans) | { | this.beans = beans; | } | When we create PropertyInfo we use getter's type (in AbstractBeanInfoFactory). But when I do a contextual injection / callback check, I use setter's type. What would be a proper fix? To use ParameterizedClassInfo over plain ReflectClassInfoImpl? Or just log a warning?

If its supposed to create a Class[] from Class, then the depth argument is irrelevant, and misleading. There is no such type as Class[int length]. If its supposed to create a depth dimensional array of Class, then its broken. Based on the existing tests, it seems to be the former and it should just be: | public static Class getArrayClass(Class clazz) | { | return Array.newInstance(clazz, 0).getClass(); | } | In terms of JBMICROCONT-123, I don't think there is a better way to do this as I see the same logic in the jdk code. So either the blind are leading the blind and that is where we got this construct from, or there is no other way to create an array Class.

[Design the new POJO MicroContainer] - Re: ClassCastException for char[] MetaValue creation

by scott.stark＠jboss.org

I have the following changes to the ArrayValue interface working and can preserve the primitive type arrays: | public interface ArrayValue<T extends Serializable> | extends MetaValue, Iterable<T> | { | ArrayMetaType<T> getMetaType(); | | /** | * Get the underlying array value. This will not be an | * Object[] in general. | * @see #getValue(int) | * | * @return the underlying value | */ | public Object getValue(); | /** | * Get the length of the array. | * @return length of the array. | */ | public int getLength(); | /** | * Get the array element at index. | * @param index - index into the array. | * @return element at index. | */ | public Object getValue(int index); | } | As this ArrayValueSupportUnitTestCase test shows, you can use the getValue(int) accessor, the type safe foreach Iterable, or the raw array: | public void testCharArray() throws Exception | { | ArrayMetaType<Character> type = new ArrayMetaType<Character>(1, SimpleMetaType.CHARACTER); | char[] value = {'h', 'e', 'l', 'l', 'o'}; | ArrayValueSupport<Character> avs = new ArrayValueSupport<Character>(type, value); | // Use getValue(int) accessor | for(int n = 0; n < avs.getLength(); n ++) | { | Object element = avs.getValue(n); | assertEquals(value[n], element); | } | // Use typesafe foreach Iterable | int i = 0; | for(Character c : avs) | { | assertEquals("["+i+"]", (Character) value[i++], c); | } | // Validate the primative array | char[] raw = (char[]) avs.getValue(); | for(int n = 0; n < value.length; n ++) | { | assertEquals(value[n], raw[n]); | } | } | There are quirks for multi-dimensional primitive arrays though. This 2d char[][] test shows them: | public void test2DCharArray() throws Exception | { | ArrayMetaType<Character[]> type = new ArrayMetaType<Character[]>(2, SimpleMetaType.CHARACTER, true); | char[][] value = {{'h', 'e'}, {'l', 'l', 'o'}}; | ArrayValueSupport<Character[]> avs = new ArrayValueSupport<Character[]>(type, value); | assertEquals(value.length, avs.getLength()); | for(int m = 0; m < value.length; m ++) | { | Object arraym = avs.getValue(m); | for(int n = 0; n < value[m].length; n ++) | { | // Have to use the java.lang.reflect.Array to access nested elements | Object valuenm = Array.get(arraym, n); | assertEquals("["+m+"]["+n+"]", value[m][n], valuenm); | } | } | // Use typesafe foreach Iterable: current broken with CCE on [C | int i = 0, j = 0; | for(Character[] carray : avs) // CCE here | { | for(Character c : carray) | { | Character cij = value[i ++][j ++]; | assertEquals("["+i+"], ["+j+"]", cij , c); | } | } | // Validate the primitive 2d array | char[][] raw = (char[][]) avs.getValue(); | for(int m = 0; m < value.length; m ++) | { | for(int n = 0; n < value[m].length; n ++) | { | assertEquals("["+m+"]["+n+"]", value[m][n], raw[m][n]); | } | } | } | The first is that you have to use java.lang.reflect.Array.get(Object, int) to access the elements of the nested arrays obtained via the get(int) accessor. The second is that the Iterable implementation on ArrayValueSupport needs to track whether the underlying value is a primitive array, and covert it to the primitive wrapper form to avoid the CCE. Before going further I want to see if we agree that this is the way to go.

[Design of JBossXB] - Re: xsd:attribute ref unsupported in unmarshaller

by anil.saldhana＠jboss.com

I made the attribute ref change to my schema this week (and not checked in AS trunk yet). Yesterday while debugging something, saw this issue. Do you want me to create some kind of a test case for this? It will take a day or two (I am travelling). I am guessing that you should be able to pull out a quick test case yourself. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071988#4071988 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4071988

[Design of JBoss Wiki] - Wiki portlet depends on wiki page?

by mimra

Hi I am using the latest JBoss Wiki on As 4.0.5 and Portal 2.6.1. It seems that the Wiki portlet somehow needs a wiki page with the wiki portlet instance on it. For example if I create a new page and add the wiki portlet intance to that page and delete the page called 'wiki', then bavigation with the wiki portlet fails. It seems to me that regardless of the configuration you have made (other pages with the wiki portlet instance and also the dashboard) navigating pages with the wiki portlet always takes you back to the 'original' wiki - if it still exists... Has anyone else seen this? /Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071954#4071954 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4071954

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Count Messages with Selector and Edit Message

by hendra_netm

hi Tim, Thank you for your reply. As far as I know, List All Messages will return list of messages. I think this will cause problem if we have many messages and each has big size. What I think is, may be we also need another method to count message with selector. So you only get the integer, and not the content of the message.
