i need separate log file each input file processed. have written app using java,log4j,javamail api validate xml.it takes input ini files(to path of xml file validated).once file processed, should generate log file before going next file file name. have trigger error mail each , every ini file if has errors. present status: took xml path ini file name,validated,but generating single log if process multiple file.i need separate log files each , every log files.i attach entire source code this. kindly me how achieve using java log4j
my piece of java code:
static void sendmail() throws ioexception, messagingexception,addressexception { string to1=carparser1.to1; dateformat dateformat = new simpledateformat("dd/mm/yyyy hh:mm:ss"); calendar cal = calendar.getinstance(); string to2 = carparser1.to2; string to3= carparser1.to3; string to4=carparser1.to4; string = carparser1.from; string host = carparser1.host; properties properties = system.getproperties(); properties.setproperty("mail.smtp.host", host); session session = session.getdefaultinstance(properties); mimemessage message = new mimemessage(session); int m_toterr,m_totwarn; string getfilepath=""; string pathlogfile = "d:/logfile.log"; enumeration enumeration = carparser1.logger.getrootlogger().getallappenders(); try { m_toterr=validatexml.total_err; message.setfrom(new internetaddress(from)); message.addrecipient(message.recipienttype.to, new internetaddress(to1)); message.setsubject("re : car validation report @ : "+dateformat.format(cal.gettime())); while ( enumeration.hasmoreelements() ) { appender appender = (appender) enumeration.nextelement(); if ( appender instanceof fileappender ) { pathlogfile = ((fileappender)appender).getfile(); //here path break; } } stringbuffer sb = new stringbuffer(); fileinputstream fstream = new fileinputstream(pathlogfile); bufferedreader br = new bufferedreader(new inputstreamreader(fstream)); string singleline; while ((singleline = br.readline()) != null) { if(singleline.startswith("error")|| singleline.startswith("pls")|| singleline.startswith("total")){ sb.append(singleline + "<br><br>"); } } br.close(); string alllines = sb.tostring(); message.setcontent(alllines, "text/html; charset=iso- 8859-1"); transport.send(message); system.out.println("email sent successfully...."); carparser1.logger.info("email sent successfully..."); system.out.println(); } catch (messagingexception mex) { system.out.println("invalid email address.please provide valid email id send with"); mex.printstacktrace(); } } } my log4j.properties:

thanks in advance expecting have got dead-lined submit today.
code separate log file:
file dir=new file("d:/newlog"); if(!dir.exists()){ dir.mkdir();} string filename=carparser1.si_orderid; file logfile=new file(dir,filename+"_log.txt"); if(!logfile.exists()){ logfile.createnewfile(); } fileutils.writestringtofile(logfile,carparser1.sb.tostring()); //appending sb.append("\ncar validating @ path:"+final_filepath+" order id :"+si_orderid); sb.append("\nunit id : "+si_unitid+" order id: "+si_orderid); but getting o/p
java version 1.7 or below supported car validating @ path:\fms\fms_workarea\bdops\opsbank-ii\signals\eflow\car\abpel\january-2016\batch_16.01.16\6668662\itemfile order id :6668662unit id : 2518073 order id: 6668662order id equalunit idequalsupplier id equal
as dump no next line though wrote on code. please guide me results written read , line line out put read.
thanks in advance
how log4j works: log files written file configuration mentioned in log4j.properties/.xml. example : log4j.appender.rollingappender.file=d:\logfile.log
we can configure different level of logging info,debug,error different log file.
for requirement of writing different log files different input files, please following. 1) create stringbuffer object , append information want log 2) create new file object required name , dump stringbuffer object.
