com.crimetrack.service.monitoringmanager.getmonitoringstdate(monitoringmanager.java:60)

public string getmonitoringstdate(integer crimerecno,             integer socialsecuritynumber) throws exception {          return this.getmonitoringstdate(crimerecno, socialsecuritynumber);     }

dao getmonitoringstdate

public string getmonitoringstdate(integer crimerecno, integer socialsecuritynumber){      //select minimum start date in event there several records although not allowed     string sql = "select ifnull(min(monitoringstdate),'0') monitoringstdate tblmonitoring crimerecno = ? , socialsecuritynumber = ?";      string monitoringstdate = (string)getjdbctemplate().queryforobject(sql, new object[]{crimerecno,socialsecuritynumber}, string.class);      return monitoringstdate; }

i have following listeners registered:

listeners

 <listener>           <listener-class>org.springframework.web.context.contextloaderlistener</listener-class>      </listener>       <listener>          <listener-class>org.springframework.web.context.request.requestcontextlistener</listener-class>     </listener>

code

dao

public boolean hasmonitoringrecord(integer crimerecno, integer socialsecuritynumber){          //select count of monitoring records there should 1 monitoring record         string sql = "select count(*) monitoringstdate tblmonitoring crimerecno = ? , socialsecuritynumber = ?";          integer count = (integer)getjdbctemplate().queryforobject(sql, new object[]{crimerecno,socialsecuritynumber}, integer.class);          if(count > 0 ){              return true;         }else{             return false;         }      }

if(result.haserrors()){      mymonitoringtypelist.put("monitoringtypelist",this.monitoringtypemanager.getlistofmonitoringtype());     model.addattribute("icon", "ui-icon ui-icon-circle-close");     model.addattribute("results", "error: unable save record!");     model.addattribute("monitoringtype",mymonitoringtypelist);     model.addattribute("monitoring",monitoring);     model.addattribute("records", session.getattribute("records"));     model.addattribute("crimerecno",session.getattribute("crimerecno"));       //return user page on not first page 1 error     return new modelandview("monitoringlist","page",session.getattribute("page")); }else{      int crimerecno = monitoring.getcrimerecno();     int socialsecuritynumber = monitoring.getsocialsecuritynumber();          logger.info("no errors going process records");         logger.info("crimerecno " + monitoring.getcrimerecno());         logger.info("socialsecurity number  " + monitoring.getsocialsecuritynumber());         //check if record exists. if 1 exist update else insert         //to check if record exists can start date          string dbmonitoringstdate = monitoringmanager.getmonitoringstdate(crimerecno,socialsecuritynumber);          logger.info("the dbmonitoringstdate " + dbmonitoringstdate);          if(monitoringmanager.hasmonitoringrecord(crimerecno, socialsecuritynumber)){             logger.info("has monitoring record");             //do update              monitoringmanager.updatemonitoringrecord(monitoring);             model.addattribute("icon", "ui-icon ui-icon-circle-check");             model.addattribute("results", "record updated");         }else {             logger.info("does not have monitoring record");             //do insert             monitoringmanager.savemonitoringrecord(monitoring);             model.addattribute("icon", "ui-icon ui-icon-circle-check");             model.addattribute("results", "record saved");         }

look @ method definition:

public string getmonitoringstdate(integer crimerecno,                                   integer socialsecuritynumber) throws exception {     return this.getmonitoringstdate(crimerecno, socialsecuritynumber); }

the thing method calling itself. obviously, have infinite recursion loop.
