In such a case we have to check if there is another process that is running on the same port.
You can know this by running the Resource Monitor (Start>>All Programs>>Accessories>>System Tools>>Resource Monitor). If the found program is something you cannot live without it, than you will have to change the port used by the Collect Tomcat instance. In order to do this, you have to change the file c:\opt\openforis\collect\tomcat\conf\server.xml (take a backup copy first) and modify the values of the port attributes specifying something different from the original values.
You can find an alternative version of the server.xml file at this address: server.xml
Rename the original server.xml file into server.old, download the new server.xml file and put it inside the conf folder.
With this file Collect will work on port 8580, so after Collect will start up, you will have to access it using this link from your web browser: Collect on port 8580 link
Let us know, many thanks.
