Perl - Unable to call java jar file

Question

system("java -jar \"TRNDHTMLtoPDF.jar\" \"test.pdf\" \"c.txt\" ");

Above code used to run a java jar file from Perl (cgi) page. When I run it from command prompt, it working fine, but when i try to run from a page, nothing happened, no error and no output.

$result= `"java -jar \"TRNDHTMLtoPDF.jar\" \"test.pdf\" \"c.txt\" "`;

When I try to print the $result. it show empty. Seems like the jar not executed at all. How do I solve this? Please advice.

Answer 1

You should try to use the character ' at the beginning and at the end. No escape with \\ should be needed anymore.
