Using HTML caller in case the command line is too long

Whenever the command line sent exceeds 8192 characters, an error message is displayed ("filename or extension is too long"). In this case, it is necessary to use a dedicated tool to send MetaServlet API commands.

1. Make sure your Talend Administration Center is up and running, and its license is up to date.
2. Make sure you were provided the HTML MetaServlet caller tool. If it is not the case, contact Talend Support team.
3. Open MetaServlet.html. An HTML page is displayed in your browser.
4. Enter the command in json-params field and click Call MetaServlet button to send the command.
