Connection issue to Talend Administration Center during Talend CommandLine's task generation

When generating a Job with the Talend CommandLine, the HTTP connection to Talend Administration Center might fail and you might encounter the following error: 'Unexpected error, contact your administrator'

This is a specific error that sometimes happens if:

1. the Talend CommandLine application and the Talend Administration Center server are based on different machines
2. the first connection to Talend Administration Center was made on a web browser with "localhost" in the URL instead of a specific hostname or IP address.

This issue can be solved by specifying the static URL of the web application in the configuration file. To do so:

1. Make sure the Tomcat server is stopped and open the following file to edit it:

   <TomcatPath>/webapps/org.talend.administrator/WEB-INF/classes/configuration.properties

2. Uncomment the MISC PARAMETERS part and replace the value of the conf.applicationStaticLocation parameter with the URL to your Web application, as shown below:

   ############################################################### # MISC
   PARAMETERS ############################################################### #
   Specify and url for static location or comment the line for dynamic compute:
   conf.applicationStaticLocation=
   http://serverName:8080/org.talend.administratorCopy code to clipboard

3. Save your changes and re-start your Tomcat server.

   From now on, the static URL you defined will be called every time during the task generation process.
