java - SSL chain validation failed with intermediate cert -

-

i want understand way validation chain works. certs need in truststore?

i have chain root ca -> intermediate 1 -> intermediate 2 -> server cert. have intermediate 2 cert in truststore. on 1 test machine works right, on other not (contacting different server similar configuration). popular suncertpathbuilderexception: unable find valid certification path requested target exception. server sends full chain. guess solution put whole chain root ca truststore.

i want know why works on 1 machine , not other. possible have influence on how chain validation works? can server require full chain validation?

i not figure out, if default truststore jdk automatically included or not. 2 machines have different jdk versions 1.7.0_21 (not working) , 1.7.0_25 (working). matter?

one more thing: suncertpathbuilderexception - possible find out part of chain not like?

i happy hints. thanks, heike

you need certificate of any of signers in certificate chain. typically topmost one.

i have @ chain visible -djavax.net.debug=ssl,handshake , @ local truststore file make sure @ least 1 of certificates in chain present same signature, date, subjectdn, issuerdn etc in debug log.

i'm trying create program sum n-1 , n-2 numbers create n , store value in array. currently, output (assuming numdisp > 2 ) num1 , num2 , 0 , 0 , 0 ... size of array correct, i'm having issues reassigning elements. num1 = input('input first integer of fibonacci sequence: '); num2 = input('input second integer of fibonacci sequence: '); numsdisp = input('how many integers display? --> '); list = zeros(numsdisp,1); list(1) = num1; list(2) = num2; if (numsdisp <=0) disp('value must integer greater zero.') elseif (numsdisp == 1) disp(num1) elseif (numsdisp == 2) disp(num1) disp(num2) else disp(num1) disp(num2) index = 3:numsdisp disp(list(index)) list(index) = list((index-1)) + list((index-2)); end end example input: 3 3 4 corresponding output: 3 3 0 0 you aren't printing out final result, intermediate steps. in for loop, printing list(index) updating value, rather updat...

i have php code pulls info database. uses prepared statement, works fine written below: <?php $n = '5'; if ($stmt = $connection->prepare("select title items id = ?")) { $stmt->bind_param("s", $n); $stmt->execute(); $stmt->bind_result($title); while ($stmt->fetch()) { echo $title; } $stmt->close(); } ?> and let's echo "batman". however, when move placeholder here: "select ? items id = 5" and change: $n = 'title'; instead of echoing "batman", echoes "title". not possible use placeholder select parameter? what have done this: select "title" items id = 5 you cant use prepared statement bindings identifiers, parameters.
