wildfly部署ejb，访问时出错EJBCLIENT000025

Question

我在ubuntu下有个wildfly。

先新建一个ejb项目，用eclipse部署wildfly上。

再写一个 java client访问ejb：出错

我的jboss-ejb-client.properties:

remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

remote.connections=default

remote.connection.default.host=localhost
remote.connection.default.port = 8080

我的client代码是照着官网写的：

各位 帮帮我吧。困我好久了

Answer 1

remote.connection.default.host=localhost, 这个地址要和jboss部署配置standalone.xm中的发布地址要一致. 最好用IP地址!
