    <description>Hi, 
&lt;BR /&gt;I have an ESB service exposed as a web service.It was built on Talend ESB studio 5. I am able to invoke it via SOAP UI. I would like to invoke the job through the browser. For this I have tried hitting it as 
&lt;BR /&gt;&lt;A href="http://hot" target="_blank"&gt;http://hot&lt;/A&gt; 
&lt;span class="lia-inline-image-display-wrapper" image-alt="0683p000009MAB6.png"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/158321i00588DF41617C922/image-size/large?v=v2&amp;amp;px=999" role="button" title="0683p000009MAB6.png" alt="0683p000009MAB6.png" /&gt;&lt;/span&gt;ort/services/DummyService?method=runJob&amp;amp;args=--context_param%20testid=123 
&lt;BR /&gt;but I get SOAP fault. When I check the logs it gives 
&lt;BR /&gt;11:42:55,751 | INFO | ram%20testid=123 | ernal.GenericServiceProviderImpl 72 | - - | Invoke operation 'null' 
&lt;BR /&gt;. 
&lt;BR /&gt;. 
&lt;BR /&gt;. 
&lt;BR /&gt;Caused by: java.lang.NullPointerException 
&lt;BR /&gt; at org.talend.esb.job.controller.internal.GenericServiceProviderImpl.invoke(GenericServiceProviderImpl.java:74) 
&lt;BR /&gt; at org.talend.esb.job.controller.internal.GenericServiceProviderImpl.invoke(GenericServiceProviderImpl.java:42) 
&lt;BR /&gt;I think it was not able to find the operation to invoke. Hence I tried to add the operation as well in the url like 
&lt;BR /&gt;&lt;A href="http://host" target="_blank"&gt;http://host&lt;/A&gt; 
&lt;span class="lia-inline-image-display-wrapper" image-alt="0683p000009MAB6.png"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/158321i00588DF41617C922/image-size/large?v=v2&amp;amp;px=999" role="button" title="0683p000009MAB6.png" alt="0683p000009MAB6.png" /&gt;&lt;/span&gt;ort/services/DummyService/DummyServiceOperation?method=runJob&amp;amp;args=--context_param%20testid=123 
&lt;BR /&gt;I get a soap fault as 
&lt;BR /&gt;&amp;lt;soap:Fault&amp;gt;&amp;lt;faultcode&amp;gt;soap 
&lt;span class="lia-inline-image-display-wrapper" image-alt="0683p000009M9p6.png"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/134116iFBD5D7F21624A744/image-size/large?v=v2&amp;amp;px=999" role="button" title="0683p000009M9p6.png" alt="0683p000009M9p6.png" /&gt;&lt;/span&gt;erver&amp;lt;/faultcode&amp;gt;&amp;lt;faultstring&amp;gt;Parameter should be ordered in the following sequence: &amp;lt;/faultstring&amp;gt;&amp;lt;/soap:Fault&amp;gt; 
&lt;BR /&gt; 
&lt;BR /&gt;Could someone please guide me on how to invoke the service. Its a simple service which creates a log file.</description>
