Hazelcast类路径错误

我想使用voldemort商店来保存hazelcast中的数据。我实现了mapstore接口。当我尝试在hazelcast中添加地图项时，我得到这个异常。Hazelcast类路径错误

这是我编辑过的hazelcast run.sh脚本，以便在类路径中包含voldemort jar。

#!/bin/sh 
java -Djava.net.preferIPv4Stack=true -cp  ./:/home/gerrard/workspace/hazelcast/bin/:/home/gerrard/work/voldemort- 0.90.1/lib/:/home/gerrard/work/voldemort-0.90.1/dist/:/home/gerrard/work/voldemort- 0.90.1/bin/:../lib/hazelcast-2.0.1.jar com.hazelcast.examples.TestApp

我也在hazelcast.xml文件中添加了我的实现类。

我还在hazelcast-2.0.1.jar的清单文件中添加了一个类路径条目。

即使这样，当我尝试添加一个条目时，它会给出此noclassdef发现的错误。它试图找到的类肯定是在我添加到类路径的voldemort文件夹中。我仍然不知道问题是什么。有人可以提出其他解决方案吗？谢谢。

您可以尝试Hazelcast配置并自己设置工厂对象。

// Build the config from xml file you have in the classpath 
Config config = new XmlConfigBuilder().build(); 
MapStoreConfig msc = new MapStoreConfig.. 
msc.setFactoryImplementation(new StoreClientFactory()); 
MapConfig mapConfig = new MapConfig.. 
mapConfig.setMapStoreConfig(msc); 
config.addMapConfig(mapconfig); 

// init Hazelcast with this configuration 
// make sure you call init fore any other Hazelcast operation!! 
Hazelcast.init(config); 

// then access to your map 
Map map = Hazelcast.getMap("mymap");
