I'm uploading the files on the server like this: I create folder on the server and then I put all my uploading files in this folder
#Override
public String executeAction(HttpServletRequest request,
List<FileItem> sessionFiles) throws UploadActionException {
String response = "";
int cont = 0;
userNumber = request.getParameter("userNumber");
File f = new File(ConfAppServer.getRealContextPath() + "/edoc/"
+ userNumber);
for (FileItem item : sessionFiles) {
if (false == item.isFormField()) {
cont++;
try {
String extension = item.getName().substring(
item.getName().length() - 3);
File file = null;
file = new File(ConfAppServer.getRealContextPath()
+ "/edoc/"
+ userNumber
+ System.getProperty("file.separator")
+ item.getName().substring(0,
item.getName().length() - 4) + "."
+ extension);
item.write(file);
receivedFiles.put(item.getFieldName(), file);
receivedContentTypes.put(item.getFieldName(),
item.getContentType());
response += "<file-" + cont + "-field>"
+ item.getFieldName() + "</file-" + cont
+ "-field>\n";
response += "<file-" + cont + "-name>" + item.getName()
+ "</file-" + cont + "-name>\n";
response += "<file-" + cont + "-size>" + item.getSize()
+ "</file-" + cont + "-size>\n";
response += "<file-" + cont + "-type>"
+ item.getContentType() + "</file-" + cont
+ "type>\n";
} catch (Exception e) {
throw new UploadActionException(e);
}
}
}
removeSessionFileItems(request);
return "<response>\n" + response + "</response>\n";
}
It works ver well on my colleague computer, but on my computer I get an error
There is an error in file name. Help me please fix my problem. Thanks.
As you can see the file name is not displaying correcly. So the problem is the encoding of the Request/Response. You need to add a filter servlet. Here is a tutorial.

I am having an arraylist fetching name and status of a person. Arraylist is storing the status and name. Its displaying one name at a time. How can I be able to display multiple names at once in alert dialog?
private ArrayList getunfiledRogspDoctorList() {
SqlDataStore sd = new SqlDataStore(this);
sd.open();
String gspQuery = " SELECT * FROM "+ TABLE_DOCTOR + " WHERE " + Queryclass.DOCTOR_ROGSP_STATUS + " == " + 0 + " AND " + Queryclass.DOCTOR_DATE_ID + " = '" + selectionID + "'";
Cursor gspCu = sd.getData(gspQuery);
if(gspCu.moveToFirst()){
do {
rogspname = gspCu.getString(gspCu.getColumnIndex(Queryclass.DOCTOR_CONTACTNAME));
unfiledrogspDoctorList.add(gspCu.getString(gspCu.getColumnIndex(Queryclass.DOCTOR_ROGSP_STATUS)) + rogspname);
}while (gspCu.moveToNext());
}
gspCu.close();
sd.close();
System.out.println("unfiledrogspDoctorList "+unfiledrogspDoctorList);
return unfiledrogspDoctorList;
}
From the code, you are having an ArrayList of your target display String in unfiledrogspDoctorList:
// Suggest to also define the type of your returning ArrayList
private ArrayList<String> getunfiledRogspDoctorList() {
// Define a local ArrayList
ArrayList<String> unfiledrogspDoctorList = new ArrayList<>();
SqlDataStore sd = new SqlDataStore(this);
sd.open();
String gspQuery = " SELECT * FROM "+ TABLE_DOCTOR + " WHERE " + Queryclass.DOCTOR_ROGSP_STATUS + " == " + 0 + " AND " + Queryclass.DOCTOR_DATE_ID + " = '" + selectionID + "'";
Cursor gspCu = sd.getData(gspQuery);
if(gspCu.moveToFirst()){
do {
rogspname = gspCu.getString(gspCu.getColumnIndex(Queryclass.DOCTOR_CONTACTNAME));
unfiledrogspDoctorList.add(gspCu.getString(gspCu.getColumnIndex(Queryclass.DOCTOR_ROGSP_STATUS)) + rogspname);
}while (gspCu.moveToNext());
}
gspCu.close();
sd.close();
System.out.println("unfiledrogspDoctorList "+unfiledrogspDoctorList);
return unfiledrogspDoctorList;
}
You can consider to convert your ArrayList of String into just a String.
private String concat(ArrayList<String> unfiledrogspDoctorList) {
StringBuilder sb = new StringBuilder();
for (String item : unfiledrogspDoctorList) {
sb.append(item);
sb.append(","); // Or change into other separate you would like to display
}
sb.setLength(Math.max(0, sb.length() - 1)); // Remove the appending character
return sb.toString();
}
Then you can make use of an AlertDialog to display that concatenated String.
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder
.setMessage(concat(getunfiledRogspDoctorList()))
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// Do anything upon pressing OK button
}
);
AlertDialog alert = builder.create();
alert.show();
You could use :-
SELECT group_concat(name) FROM ....
or to place each on a line you could change the default comma separator to a line feed using
SELECT group_concat(name,'\n') FROM ....
.... representing the rest of the SQL in the question
See https://www.sqlite.org/lang_aggfunc.html#group_concat
note that the GROUP as no GROUP BY clause is provided is a single group (and therefore output row) made up of ALL extracted rows.
Using the WordCount.java example to test metrics. The PrintMetricsFn function (see below) prints the metrics correctly once the pipeline is finished, but fails when called while the pipeline is processing. DirectRunner and FlinkRunner both throw exceptions (null input), while SparkRunner prints only the header line (similar to "* Metric Values *").
private static void PrintMetricsFn(final MetricsFilter inputFilter) {
final MetricResults metrics = result.metrics();
final MetricQueryResults returns = metrics.queryMetrics(inputFilter);
final Iterable<MetricResult<Long>> counters = returns.getCounters();
System.out.println("*** Metric Values ***");
for(final MetricResult<Long> s: counters){
System.out.println(s.getName().getNamespace() + ":" +
s.getName().getName() + ":" + s.getStep() + ": count=" +
s.getAttempted()) ;
}
final Iterable<MetricResult<DistributionResult>> dist = returns.getDistributions();
for (final MetricResult<DistributionResult> d: dist) {
System.out.println(d.getName().getNamespace() + ":" +
d.getName().getName() + ":" + d.getStep() + ": sum=" +
d.getAttempted().getSum() + ", count=" +
d.getAttempted().getCount() + ", min=" +
d.getAttempted().getMin() + ", max=" +
d.getAttempted().getMax() + ", mean=" +
d.getAttempted().getMean());
}
final Iterable<MetricResult<GaugeResult>> gauge = returns.getGauges();
for (final MetricResult<GaugeResult> g: gauge) {
System.out.println(g.getName().getNamespace() + ":" +
g.getName().getName() + ":" + g.getStep() + ": gauge=" +
g.getAttempted().getValue());
}
return;
}
Here are the declarations for the external variables:
private static PipelineResult result;
private static MetricQueryResults returns;
private static MetricsFilter mFilter;
And here's where the mFilter and result variables are set:
mFilter = MetricsFilter.builder()
.addNameFilter(MetricNameFilter.named("ExtractWordsFn", "emptyLines"))
.addNameFilter(MetricNameFilter.named("ExtractWordsFn", "lineLenDistro"))
.addNameFilter(MetricNameFilter.named("ExtractWordsFn", "maxLineLen"))
.build();
result = p.run();
Finally, here's the function that calls PrintMetricsFN without success:
#ProcessElement
public void processElement(#Element final String element, final OutputReceiver<String> receiver) {
lineLen = element.length();
lineLenDist.update(lineLen);
if (element.trim().isEmpty()) {
emptyLines.inc();
}
if (lineLen > localMax) {
localMax = lineLen;
maxLineLen.set(localMax);
}
if((lineCnt++ % 10) == 0) {
PrintMetricsFn(mFilter);
}
// Split the line into words.
final String[] words = element.split(ExampleUtils.TOKENIZER_PATTERN, -1);
// Output each word encountered into the output PCollection.
for (final String word : words) {
if (!word.isEmpty()) {
receiver.output(word);
}
}
}
And for completeness, here's the error I get from DirectRunner:
Caused by: java.lang.NullPointerException
at org.apache.beam.examples.WordCount.PrintMetricsFn(WordCount.java:158)

I'm trying to intercept all classes that contains a specific word in their package name... something as below:
#Pointcut("execution(* *..service..*.*(..))")
I have all the classes in the packages to intercept:
com.domain.model.user.service.save(User user);
com.domain.model.user.service.impl.save(XPTO xpto);
com.domain.model.foo.service.HelloWorld.getMessage(Foo foo);
In short, i would like to intercept all the methods in the classes that belong to the
package *service*

Try this. Perhaps you have to exclude your aspect classes to avoid endless loops. This example catch all methods with com..login..* in package

I think you can capture what you need with a pointcut like this:
before(): execution(* *(..)) &&
(within(*..service..*.*) || within(service..*.*) || within(*..service.*)) {}
The three within clauses capture the three alternatives:
within(*..service..*.*): 'service' is somewhere in the package name but not at the start or end
within(service..*.*): 'service' is at the start of the package name (maybe this can't happen in your scenario)
within(*..service.*)): 'service' is at the end of the package name
If you need to capture serviceFoo variants you could add further wildcards around service (I think): within(*..*service*.*)
You should use a pointcut expression like this:
within(your.base.package..service..*)
restrict to at least your base package (typically this is not an issue)
match 'service' keyword in your package name at any level
for example, this will match those classes :
your.base.package.service.ServiceClass
your.base.package.service.customer.ServiceClass
your.base.package.internal.service.ServiceClass
your.base.package.internal.service.customer.ServiceClass

suppose there is a class which contains 4 fields.i have to read these value from xml file and set that value to fields
the xml file is like that
<Root>
<Application >
<AppName>somevalue</AppName>
<IdMark>somevalue</IdMark>
<ClassName>ABC</ClassName>
<ExecName>XYZ</ExecName>
</Application>
<Application>
<AppName>somevalue</AppName>
<IdMark>somevalue</IdMark>
<ClassName>abc</ClassName>
<ExecName>xyz</ExecName>
</Application>
</Root>
now i have to read all the values from xml file and set each value to particular fields.
i hav done reading of the xml file
and i saved the retrieved value in arraylist.
the code is like that
public class CXmlFileHook
{
string appname;
string classname;
string idmark;
string execname;
string ctor;
public CXmlFileHook()
{
this.appname = "Not Set";
this.idmark = "Not Set";
this.classname = "Not Set";
this.execname = "Not Set";
this.ctor = "CXmlFileHook()";
}
public void readFromXmlFile(string path)

break;
case "ExecName":
oRreader.Read();
//strNodeValues[3] = oRreader.Value;
oArrayList.Add(oRreader.Value);
break;
}
}
}
Console.WriteLine("Reading from arraylist");
Console.WriteLine("-------------------------");
for (int i = 0; i < oArrayList.Count; i++)
{
//Console.WriteLine("Reading from Sting[]"+ strNodeValues[i]);
Console.WriteLine(oArrayList[i]);
}
//this.appname = strNodeValues[0];
//this.idmark = strNodeValues[1];
//this.classname = strNodeValues[2];
//this.execname = strNodeValues[3];
this.appname = oArrayList[0].ToString();
this.idmark = oArrayList[1].ToString();
this.classname = oArrayList[2].ToString();
this.execname = oArrayList[3].ToString();
}
static string vInformation;
public void showCurrentState(string path)
{

oStreamWriter.WriteLine(vInformation);
oStreamWriter.Flush();
oStreamWriter.Close();
oFileStream.Close();
}
}
here i set set the fields according to arraylist index but i dont want
is there any another solution for this....
Since there are libraries like Commons Digester why should one write such raw code to achieve this.
