java - NoClassDefFoundError when code moved from R2007a to R2013a -

-

i working on moving code r2007a r2013a. getting java.lang.noclassdeffounderror during run in r2013a not appear in r2007a. occurs when call.

feval('get',fname,jevent);

where fname product.proxyfield object object filter , jevent product.format.java.internal.javaevent. class in jar file on path , being accessed class in same jar file. stack trace not leave realm of product if helps.

i not have access original code jar file. have access code derived original code , both classes in same package. i'm guessing has differences in java version i'm not sure since don't have original code recompile.

unfortunately can't provide actual source or full detail google search yielded results matlab startup issues. thoughts?

seems difference between r2007a , r2013a first uses 1.5 jre , second uses 1.6 jre. easier if provided stack trace showing exception. classes moved around in between jvm versions, having actual missing classes in determining if missing class class moved around different package. take missing class, google adding same exception message put above , seeing else ran similar issues.

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
