How to proceed to the next iteration of a loop whenever the program fails to read files

I'm creating a program that can read .log files in certain directories and then dumps the data from the .log files into a local database.
However, i noticed in my testing that whenever the program reads the files and i happen to access the files during the test run - the program freezes.
How do i solve this issue?
public static void file(File[] files)
{
try
{
for (File lister : files)
{
System.out.println("HERE " + lister);
in = new FileReader(lister);
br = new BufferedReader(in);
try
{
while ((sCurrentLine = br.readLine()) != null)
{
if (sCurrentLine.contains("Performance"))
{
String[] aCurrentLine = sCurrentLine.split("\\|");
if (aCurrentLine.length >= 6) {
Date date = dateinsert.parse(aCurrentLine[0]);
CurrentTime = dateinsert.format(date);
CurrentFlow = aCurrentLine[2];
CurrentModule = aCurrentLine[5];
CurrentType = aCurrentLine[4];
sCurrentID = aCurrentLine[6];
aCurrentLine = aCurrentLine[6].split("ORDER_ID");
if (aCurrentLine.length >= 2)
{
aCurrentLine[1] = aCurrentLine[1].replace (":", "");
aCurrentLine[1] = aCurrentLine[1].replace (" ", "");
aCurrentLine[1] = aCurrentLine[1].replace ("_", "");
aCurrentLine[1] = aCurrentLine[1].replace ("{", "");
aCurrentLine[1] = aCurrentLine[1].replace ("}", "");
aCurrentLine = aCurrentLine[1].split ("\"");
sCurrentID = aCurrentLine[2];
}
else // Happens when there's no order id
{
sCurrentID = "N/A";
}
cal = Calendar.getInstance();
year = cal.get(Calendar.YEAR);
month = cal.get(Calendar.MONTH);
datenum = cal.get(Calendar.DAY_OF_MONTH);
hour = cal.get(Calendar.HOUR_OF_DAY);
minute = cal.get(Calendar.MINUTE);
second = cal.get(Calendar.SECOND);
if (month<9)
{
month = month + 1;
smonth = "0" + Integer.toString(month);
}
else
{
month = month + 1;
smonth = Integer.toString(month);
}
if (datenum<10)
{
sdatenum = "0" + Integer.toString(datenum);
}
else
{
sdatenum = Integer.toString(datenum);
}
if (hour<10)
{
shour = "0" + Integer.toString(hour);
}
else
{
shour = Integer.toString(hour);
}
if (minute<10)
{
sminute = "0" + Integer.toString(minute);
}
else
{
sminute = Integer.toString(minute);
}
if (second<10)
{
ssecond = "0" + Integer.toString(second);
}
else
{
ssecond = Integer.toString(second);
}
scalendar = Integer.toString(year) + "-" + smonth + "-" + sdatenum + " " + shour + ":" + sminute+ ":" + ssecond;
ls.insertdata(sCurrentID, CurrentTime, CurrentFlow, CurrentModule, CurrentType, scalendar);
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
flag = 0;
}
}

1 - Do you need to worry about the fact that it does not work when the file is open or are you just interested in why it does not work as expected ?
2 - All of the code that you wrote to determine the value for scalendar can be reduced to 2 lines of code :
Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String formattedDate = formatter.format(Calendar.getInstance().getTime());
Here is unit test
#Test
public void quickTest() {
Format formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String formattedDate = formatter.format(Calendar.getInstance().getTime());
System.out.println(formattedDate);
}
where the result will look similar to : 2018-03-19 06:42:58

xmlhttp.status returns 0

I have this java script code for ajax and I'm having trouble of get response.
xmlhttp.status always become 0. I have repeatCallHr Servlet and getting parameters from jsp page as follows.
function loadResults() {
var tt = document.getElementById("StartDate");
alert(tt);
if (xmlhttp) {
var query = "repeatCallHr?skill="
+ document.getElementById("ServiceCode").value
+"&startDate="+document.getElementById("StartDate").value
+"&startTime="+document.getElementById("StartTime").value
+"&endDate="+document.getElementById("EndDate").value
+"&endTime="+document.getElementById("EndTime").value;
xmlhttp.open("GET", query, true);
xmlhttp.onreadystatechange = loadStallsResponse;
xmlhttp.send(null);
} else {
alert("Browser not supported!");
}}
In following code I'm calling AJAX request and try to get response out of it.
function loadStallsResponse() {
alert("come here");
alert(xmlhttp.readyState);
if (xmlhttp.readyState == 4) {
alert("status is :"+xmlhttp.status);
if (xmlhttp.status == 200) {
resultList = [];
if (xmlhttp.responseText.indexOf("Error") == -1) {
alert("come to inside of status::")
console.log(xmlhttp.responseText);
stallList = $.parseJSON(xmlhttp.responseText);
populateStallData();
} else {
alert(xmlhttp.responseText);
}
} else {
alert("Error in loading salesman data");
}
}}
function populateStallData() {
var table = "<tr><th>Date</th><th>Time</th><th>Skill</th><th>Total Call</th><th>Unique Calls</th><th>Repeat Calls</th></tr>";
for (var i = 0; i < resultList.length; i++) {
table += "</td><td width='140'>"
+ resultList[i].date
+ "</td><td width='140'>"
+ resultList[i].time
+ "</td><td width='140'>"
+ resultList[i].skill
+ "</td><td width='140'><a style='color: -webkit-link; text-decoration: underline; cursor: auto;' href='http://"
+ resultList[i].totalCall
+ "</td><td width='140'>"
+ resultList[i].uniqueCall
+ "</td><td width='140'>"
+ resultList[i].repeatCall
+ "</td></tr>";
}
document.getElementById("ResultTable").innerHTML = table;}
But it gives xmlhttp.status as 0. Please help me to figure out what is the issue.

Why won't my compiled GWT project run in a browser?

I have a GWT project which is very very simple: it's one module with a single EntryPoint that just calls GWT.log in order to tell me that it has compiled and run successfully.
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
public class Tester implements EntryPoint {
public void onModuleLoad()
{
GWT.log("I have compiled and run successfully");
}
}
It does compile - it spits out a bunch of files in the WAR folder.
My understanding of what I need to do to run it (based on http://www.gwtproject.org/doc/latest/FAQ_DebuggingAndCompiling.html) is that I need to run the hosted.html file in a browser and it will do all of its magic. I've put the entire WAR folder on a HTTP server (so that it can get the other files without being blocked by file:// stuff like I've had issues with in web development before) and fetched it in Chrome. It does nothing. I looked at the network monitor in it and recorded while refreshing the page - the only file ever loaded is hosted.html:
There are no errors or messages in the JavaScript console...
The resulting hosted.html is as follows:
<html>
<head><script>

What do I do?

Reflection recursive display of object with attributes types, names and values

I have some complex objects that I would like to print out including the attributes names, types and values. As long as I don't know in advance the amount and depth of all attributes/sub-attributes, I need a recursive call including a loop. I have done it for 2 levels
StringBuilder descr = new StringBuilder();
foreach (PropertyInfo propertyInfo in req.GetType().GetProperties())
{
if (propertyInfo.CanRead)
{
string attributValue = "";
string attributName = propertyInfo.Name;
Type attributType = propertyInfo.PropertyType;
var propertyInfoValue = propertyInfo.GetValue(req, null);
//if (attributType == typeof(XFkType))
if (attributType != typeof(System.String) &&
attributType != typeof(System.Boolean))
{
PropertyInfo[] nestedpropertyInfoArray = propertyInfo.PropertyType.GetProperties();
attributValue += "{";
foreach (PropertyInfo subProperty in nestedpropertyInfoArray)
{
// var instance = (EntityBase)Activator.CreateInstance(subClass);
attributValue += subProperty.Name + "=";
try
{
attributValue += propertyInfoValue == null ? "" : subProperty.GetValue(propertyInfoValue, null).ToString();
}
catch (Exception e)
{
attributValue += "null";
}
attributValue += ",";
}
attributValue = attributValue.Length > 1 ? attributValue.Substring(0, attributValue.Length - 1) : attributValue;
attributValue += "}";
}
else
attributValue = propertyInfo.GetValue(req, null) == null ? "" : propertyInfo.GetValue(req, null).ToString();
descr.Append("[" + propertyInfo.PropertyType + "]" + attributName + "=" + attributValue + " | ");
}
}
The result is something like:
[XPhone]class{Phone,protocol=SIP,protocolSide=User,callingSearchSpaceName=XFkType,devicePoolName=XFkType,commonDeviceConfigName=XFkType,commonPhoneConfigName=XFkType,networkLocation=Use System Default,locationName=XFkType,mediaResourceListName=null,wirelessLanProfileGroup=null,ctiid=null} | [System.UInt64]sequence={} | [System.Boolean]sequenceSpecified=False |

It's a bit difficult to understand your structures but I would expect the solution to be in the following form:
public String propertyDescription(PropertyInfo[] properties) {
StringBuilder description;
for (PropertyInfo property: properties) {
if (property.containsNestedProperties()) {
description.append(propertyDescription(property.getNestedProperties()));
} else {
description.append( ... );
}
}
return description.toString();
}

This part is supposed to add a train to the TRAININFO table in my database. I have to use mysql.
So there are some constraints I have to see before adding the train.
jTextField1.getText(); TrainNo. should not have more than 6 characters and it should be an integer.
jTextField2.getText(); TrainName. Should not have more than 30 characters.
jTextField10,jTextField12 have Depttime and araivaltime respectively.
It has 5 characters,"hr:mn" So I have to check if 'hr'<=24 and 'mn'<=59.
If the value of jTextField3.getText()==0 (number of ac1 coaches), then the trainfare for ac1 coaches (tfac1) should also be ==0.
Keeping this in mind I have tried to code it. but it doesn't work.
when ever i run this there is an error message .
Please do tell me where I am wrong.

s will always be - if !jCheckBox7.isSelected(). Think about it, you have:
if(something) {
...
} else {
s = ...;
}
if(something2) {
...
} else {
s = ...;
}
...
if(somethingN) {
...
} else {
s = "-"; //This will always be executed if !somethingN
}
You might want to have if.. else if instead of if below if.
Also note that it's not a good practice to compare boolean by writing == true. This might lead to problems if you, for example, write = instead of ==. Just write if(isTrue()) instead of if(isTrue() == true).

Basically you need to split your code into many functions. That will make it more readable.
Below is an example of how to structure your code, not a complete working code.
public void InsertTrainInfo() {
String runson = GetRunSon();
Boolean validTime1 = IsTimeValid(jTextField10.getText());
