java - JSON Unrecognized character escape ':' -

-

good day,

i doing post of json property follows:

{"db.url":"jdbc\:derby\:c\:\\users\\sasha\\unicentaopos-database;create\=true"}

and getting exception: unrecognized character escape ':' (code 58)\n @ [source: java.io.stringreader@358b85c8; line: 1, column: 480]

now, guess need replace \ \\, whenever that:

jsonstring = jsonstring.replaceall("\\", "\\\\");

i exception:

exception in thread "awt-eventqueue-0" java.util.regex.patternsyntaxexception: unexpected internal error near index 1 \  ^     @ java.util.regex.pattern.error(pattern.java:1955)     @ java.util.regex.pattern.compile(pattern.java:1702)     @ java.util.regex.pattern.<init>(pattern.java:1351)     @ java.util.regex.pattern.compile(pattern.java:1028)     @ java.lang.string.replaceall(string.java:2223)     @ com.openbravo.pos.forms.appconfig.convertconfigtojson(appconfig.java:332)     @ com.openbravo.pos.forms.appconfig.load(appconfig.java:221)     @ com.openbravo.pos.forms.appconfig.init(appconfig.java:141)     @ com.openbravo.pos.forms.appconfig.<init>(appconfig.java:70)     @ com.openbravo.pos.forms.appconfig.getappconfig(appconfig.java:78)     @ com.openbravo.pos.forms.startpos$1.run(startpos.java:99)     @ java.awt.event.invocationevent.dispatch(invocationevent.java:311)     @ java.awt.eventqueue.dispatcheventimpl(eventqueue.java:756)     @ java.awt.eventqueue.access$500(eventqueue.java:97)     @ java.awt.eventqueue$3.run(eventqueue.java:709)     @ java.awt.eventqueue$3.run(eventqueue.java:703)     @ java.security.accesscontroller.doprivileged(native method)     @ java.security.protectiondomain$javasecurityaccessimpl.dointersectionprivilege(protectiondomain.java:76)     @ java.awt.eventqueue.dispatchevent(eventqueue.java:726)     @ java.awt.eventdispatchthread.pumponeeventforfilters(eventdispatchthread.java:201)     @ java.awt.eventdispatchthread.pumpeventsforfilter(eventdispatchthread.java:116)     @ java.awt.eventdispatchthread.pumpeventsforhierarchy(eventdispatchthread.java:105)     @ java.awt.eventdispatchthread.pumpevents(eventdispatchthread.java:101)     @ java.awt.eventdispatchthread.pumpevents(eventdispatchthread.java:93)     @ java.awt.eventdispatchthread.run(eventdispatchthread.java:82)

how deal it? highly appreciated.

in properties files must escape = , : in raw java not need to.

the correct escaping (i believe) should be:

"jdbc:derby:c:\\users\\sasha\\unicentaopos-database;create=true"

i.e. need esacpe \ (and " if there any).
