Web App將不會加入Infinispan的集羣

Question

我被玩弄的Infinispan最近，曾與Infinispan的沒有經驗。

我遇到了一個有趣的問題，我想知道，如果任何人可以擺脫一些關於它的光。

我有捆綁Infinispan的罐子和有一個類添加/刪除和列表從電網項目一個獨立的Java應用程序（GridGrabber.jar）。在該應用程序創建的CacheManager如下：

DefaultCacheManager m = new DefaultCacheManager("cluster.xml"); 

應用程序的命令行中運行具有java -jar GridGrabber.jar和工作正常，當我在終端上，他們兩個集羣啓動兩個實例在一起，我可以看到的內容來自兩個節點的網格：

Sam@macbook $ java -jar GridGrabber.jar -Djava.net.preferIPv4Stack=true -Djgroups.bind_addr=127.0.0.1

現在，在這裏它變得有趣。我還有一個在AS7上部署的Web應用程序（servlet + JSP），誰的目標是提供一個實時更新網頁的數據輸入網格。該servlet基本上調用與GridGrabber相同的代碼並使用相同的cluster.xml。

當它啓動了一切部署好了，但是但由於某種原因，它不會在網格拿起其他節點，儘管它們都在同一臺機器上運行，並且看到對方沒有問題。部署信息是：

有誰知道是否有一個原因，一個在AS7部署不會看到在網格中的其他節點？在我看來，它應該可以工作，因爲它們都在尋找相同的羣集名稱（demoCluster），並且它們都使用相同的cluster.xml。該cluster.xml如下：

<infinispan 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="urn:infinispan:config:5.1 http://www.infinispan.org/schemas/infinispan-config-5.1.xsd" 
     xmlns="urn:infinispan:config:5.1"> 

    <global> 
     <transport clusterName="demoCluster"/> 
     <globalJmxStatistics enabled="true"/> 
    </global> 

    <default> 
     <jmxStatistics enabled="true"/> 
     <clustering mode="distribution"> 
     <hash numOwners="2" rehashRpcTimeout="120000"/> 
     <sync/> 
     </clustering> 
    </default> 
</infinispan> 

一件事，我已經從部署的消息注意到的是，Web應用程序似乎使用的IPv4地址和罐子似乎使用與JGroups的IPv6地址，但我不知道這是否會成爲根本原因。任何幫助讚賞。

Answer 1

我似乎做已經解決了這個問題，以下內容：

我沿着圍繞的JGroups的IPv4/IPv6地址行權，所以我不得不獨立的應用程序通過給予以下JVM參數使用IPv4： -Djava.net.preferIPv4Stack=true

在這裏需要注意的一件事 - 我從終端運行獨立的jar，並且Web應用程序從Eclipse內部部署到AS7。從終端運行JAR時傳遞JVM參數不成功。但是，也可以從Eclipse內部運行應用程序，並在運行配置「運行」菜單 - >「運行配置」 - >在Java應用程序下添加新的應用程序（或編輯現有應用程序） - >參數 - > VM參數中爲其提供JVM參數 - >在上面粘貼喜歡ipv4stack參數的方塊。

現在在Eclipse中運行兩個獨立的應用程序和Web應用程序時，他們應該加入同一集羣，並開始將消息發送到對方。

在附註上 - 在發出「放棄郵件 - 發件人不在窗口中」之後，我有一個JGroups錯誤。經過進一步調查後，事實證明，連接到（企業）VPN導致郵件被丟棄。一旦我關閉VPN，它就開始工作完美。

希望這可能會幫助有同樣問題的人。

Answer 2

如果您想在AS7中部署Infinispan實例，我強烈建議您遵循here的指導。這樣，如果最終在AS7中使用其他集羣服務，則不需要保留單獨的通信層以及其負擔等。
