java.net.SocketTimeoutException: Read timed out WebServiceTemplate.sendAndReceive(WebServiceTemplate.java:561)

Question

I am getting below exception while calling a SOAP service using WebserviceTemplate. I am using a proxy to connect to the endpoint url.

Below is my XML configuration:

    <bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">
    <property name="marshaller" ref="jaxb2Marshaller"></property>
    <property name="unmarshaller" ref="jaxb2Marshaller"></property>
    <property name="defaultUri"><value>${ws.url}</value></property>
    <property name="interceptors">  
        <list>  
            <ref local="wsClientSecurityInterceptor"/>  
        </list>  
    </property>
    <property name="messageSender" ref="messageSender"></property>
    </bean>

    <bean id="messageSender" class="org.springframework.ws.transport.http.CommonsHttpMessageSender">
    <constructor-arg ref="httpClient"></constructor-arg>
    </bean>

    <!-- This is my custom class to set the proxy -->
    <bean id="proxyConfig" class="com.somepackage.client.ProxyConfiguration">
    <property name="proxyHostPlusPort"><value>${proxy.host}:${proxy.port}</value></property>
    </bean>

    <bean id="httpParams" class="org.apache.commons.httpclient.params.HttpClientParams">
    <property name="soTimeout" value="120000" /> 
    </bean>

    <bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
    <property name="hostConfiguration" ref="proxyConfig" />
    <property name="params" ref="httpParams" />
    </bean>

    <bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="packagesToScan">
        <list><value>com.aaa.wsdl</value></list>
    </property>
    </bean>

    <bean id="wsClientSecurityInterceptor"  
    class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor">  
    <property name="securementActions" value="UsernameToken" />  
    <property name="securementUsername"><value>${ws.username}</value></property>  
    <property name="securementPassword"><value>${ws.password}</value></property>
    <property name="securementPasswordType" value="PasswordText" />
    </bean>

Sometimes I am getting below exception while calling the webservice:

org.springframework.ws.client.WebServiceIOException: I/O error: Read timed out; nested exception is java.net.SocketTimeoutException: Read timed out
at org.springframework.ws.client.core.WebServiceTemplate.sendAndReceive(WebServiceTemplate.java:561)
at org.springframework.ws.client.core.WebServiceTemplate.marshalSendAndReceive(WebServiceTemplate.java:390)
at org.springframework.ws.client.core.WebServiceTemplate.marshalSendAndReceive(WebServiceTemplate.java:383)

Even though I've set the soTimeout, I am getting this issue. What i suspect is, issue comes when proxy is down for more than 2 minutes.

Can someone guide me how can I get rid of this issue? Is setting soTimeout alone is enough or we need to set some more params?

Thanks.

You can't get rid of the proxy being down for more than two minutes, other than by using a more reliable proxy. Unclear what you're asking. — user207421, Nov 02 '17 at 02:51
How can I confirm whether it was really an issue with proxy or the actual endpoint system? — rupesh, Nov 02 '17 at 05:49

You cannot ignore lower level (hardware/network) errors, this being said you can track them and respond accordingly by adding some intelligence in your application.

For example by doing a couple of additional attempts, etc. In order to have a more robust application.

After several try you can send back a message to the user saying that there is a network issue and that is request can not be fulfilled right now and use a logger to track it.

If this is really frequent, an action should be taken at the infra level.

Use:

-> try/catch, throw exception
