ESB与不安全后端服务之间的相互SSL，"Null cert链“。

Question

我得到了以下错误：

ERROR {org.apache.synapse.transport.passthru.SourceHandler} -  I/O error: null cert chain {org.apache.synapse.transport.passthru.SourceHandler}

同时尝试在我的(自定义)代理服务和两个不安全的后端服务之间启用相互SSL。

以下是我迄今所做的工作：

1. 启用<parameter name="SSLVerifyClient">require</parameter>
2. 使用Java工具提取carbon_home/respository/resources/security/wso2carbon.jks中两个后端服务器的公共证书：

密钥工具as-5.2.1\repository\resources\security\client-truststore.jks -export -keystore C:\I_T\WS02\wso2 -file C:\wssecurity \wso2\wso2ASpublic.cert

1. 将这些证书导入ESB信任存储： 键盘工具C:\I_T\WS02\wso2esb-4.8.1\repository\resources\security\client-truststore.jks -import -file C:\wssecurity\wso2\wso2DSSpublic.cert -keystore -storepass wso2carbon -alias wso2carbonDSS
2. 对服务器客户端信任库中的ESB证书也进行了同样的操作。

我怀疑步骤2-4是不必要的，因为信任存储已经包含了这些证书。

也许这就是造成问题的原因？

如果有人想知道如何实现，我就解决了这个问题：

Configuration :

(a) Change the following in the servers(server_home) to point to the new keystores/trustores.

In esb : Changed configuration files of the following files to point to the new keystores and their passwords (as above) :

                [server_home]/repository/conf/carbon.xml            
                [server_home]/repository/conf/axis2/axis2.xml   - also set  <parameter name="SSLVerifyClient">require</parameter>
                [server_home]/repository/conf/security/cipher-text.properties
                [server_home]/repository/conf/security/secret-conf.properties
                [server_home]/repository/conf/sec.policy

Restart server.

In soap , double click on the root project folder , navigate to WS-Security Configurations tab , then add the soapui_ts.jks as a TRUST store using soapui as the password. Then when you open a request in that project, in the Request Properties panel , set the previously configured soapui_ts.jks as the value for the SSL Keystore property.

Should all be good.
