Failed to get server protocol; no such resource on this server - sparql

Question

I am trying to run the following query on Sesame:
PREFIX dbp-ontology: <http://dbpedia.org/ontology/>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX dbpedia-owl: <http://dbpedia.org/owl/>
PREFIX dbpedia-prop: <http://dbpedia.org/property/>
select ?country ?capital
where{
SERVICE <http://factforge.net/sparql>{
?country a dbp-ontology:Country .
?country dbpedia-prop:capital ?capital .
}
} LIMIT 100
The query gets successfully executed on one computer where I have Sesame installed. On another computer, Sesame reports the following error:
Query evaluation error: org.openrdf.query.QueryEvaluationException: Failed to get server protocol; no such resource on this server: http://factforge.net/sparql?queryLn=SPARQL&query=PREFIX+dbp-ontology%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2F%3E+PREFIX+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23%3E+PREFIX+dbpedia-owl%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fowl%2F%3E+PREFIX+dbpedia-prop%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fproperty%2F%3E+PREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E+PREFIX+sesame%3A+%3Chttp%3A%2F%2Fwww.openrdf.org%2Fschema%2Fsesame%23%3E+PREFIX+owl%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2002%2F07%2Fowl%23%3E+PREFIX+xsd%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema%23%3E+PREFIX+fn%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2005%2Fxpath-functions%23%3E+SELECT++%3Fcountry+WHERE+%7B+%3Fcountry+a+dbp-ontology%3ACountry+.+%7D&infer=true
What is causing this? How can it be resolved? The hyperlink above actually displays the results of the query in a browser.
UPDATE: All this is for the computer where the connection with FactForge cannot be established:
I am using 2.7.16
Executing the query via the workbench
Following is from the log file named tomcat8-stderr:

This is a repeatable issue
There are two differences between the computers:
Functional Sesame Computer - Windows 8, The folder path where Sesame data is stored is visible in the 'About' page
Sub-functional Sesame Computer - Windows 7. Folder path is not mentioned.

Answer 1

Solved the issue by reinstalling everything starting from jre. There were two versions of jre on the computer and I guess reinstalling just one after removing the previous ones did the trick. Along with jre (i.e., as a component of the Java SE package), I also reinstalled Tomcat and Sesame.
