使用p7b证书的Jboss Https配置失败

我们正在为使用Jboss作为应用服务器的应用程序实现Http到Https的转换。我们在standalone.xml文件中做了以下更改

        <subsystem xmlns="urn:jboss:domain:web:1.1" native="false" default-virtual-server="default-host">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http" redirect-port="8443"/>
            <connector name="https" protocol="HTTP/1.1" scheme="https" socket-binding="https" enable-lookups="false" secure="true">
                <ssl name="ssl" key-alias="mykey" password="changeit" certificate-key-file="C:\Programs\Siemens\JBoss7.1.0\domain\configuration\winstore.jks" protocol="TLSv1" verify-client="false"/>
            </connector>
            <virtual-server name="default-host" enable-welcome-root="false">
                <alias name="localhost"/>
                <alias name="example.com"/>
            </virtual-server>
        </subsystem>

我们从认证团队收到了p7b格式的证书，我们必须将其转换为CER格式，然后将其添加到keystore-winstore.jks中，我们正在上面的路径中使用它。但是有了上面的配置，我们在尝试重新启动jBoss时遇到了以下错误

请让我们知道潜在的问题是什么，因为这是我们理解Https的初步步骤

请注意，如果证书是自签名证书，则问题不会出现

谢谢， 帕万2
