java - keytool -genkey error: Keystore file does not exist -

-

i try create new self certified keystore file

the command use is:

keytool -genkey -selfcert -dname "cn=my name, ou=orga unit" -alias selfcertified -keypass somepass -keystore keystore.jks -storepass anotherpass -validity 365

but annoying error:

keytool error: java.lang.exception: keystore file not exist: keystore.jks

i not understand why i'm getting error. command above should create new keystore, why complaining non existing store?

generating key pair (and new keystore) has done separate operation creating self-signed certificate key.

i.e.

keytool -genkey -alias mykey -keystore store.jks keytool -selfcert -alias mykey -keystore store.jks

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
