WS02 JMS传输协议适用于Websphere MQ

Question

WS02 JMS传输协议适用于Websphere MQ

4

经过几天的查找，我无法从IBM MQ消费消息。我按照文档进行操作，但系统仍然无法正常工作。我正在使用4.8.0和MQ 7.5.0.2

错误

我检查了网络，但是没有看到来自esb到mq服务器的任何连接。

有什么想法吗？

更新

我已经在示例中配置了axis服务器($WSO2_HOME/samples/axis2Server/repository/conf/axis2.xml)，使用了完全相同的jms传输(默认)。

编译'SimpleStockQuoteService'并启动服务器后，我可以看到它运行正常。

cd wso2esb-4.8.1/samples/axis2Server/src/SimpleStockQuoteService/ && ant
cd wso2esb-4.8.1/samples/axis2Server/ && ./axis2server.sh

我还不明白为什么它在碳中无法工作！！！

您在CARBON_HOME/repository/logs/wso2carbon.log中看到任何错误吗？ - Kasun Gajasinghe

读取JNDI配置存在问题，因此您会在连接工厂中看到问题，从而无法连接到MQ服务器。ws02使用的配置文件存在一些问题。 - Neeraj Krishna

@Neeraj。我使用JmsJndiConsumer测试了/var/tmp/jndi，它可以正常工作，但我不知道为什么读取文件时会出现问题。 - user3277560

我发现让它工作的唯一方法是修改启动脚本（ws02server.sh），将MQ客户端Java库添加到类路径中。

如果MQ传输类型为BIND（ws02在与MQ服务器相同的服务器上），则还需要包括JNI库（-Djava.library.path=/opt/mqm/java/lib）。

根据文档，在repository/component/lib中复制MQ Java库并不起作用。

在Solaris和RHEL7上测试了MQ 7.5.0.2和ws02 4.8.1。
