I have a method that allows me to type part of the computer name into a jtextfield and I submit via jbutton. The cmd prompt successfully gives me the full computer name. So if I typed 111255 the command prompt will output coud111255. Query I'm using (#dsquery computer -name *%1)
This part works great. My issue is pulling the full computer name out of the batch file and assigning it to a java variable. I'm trying to append the full computer name to textArea, but it is only pulling the hardcoded value from here:
String dn = "CN=FDCD111304,OU=Workstations,OU=SIM,OU=Accounts,DC=FL,DC=NET";)
Any Suggestions on how to get the full computer name appended to textArea?
sendParam() passes half of computer name into batch script to find full computer name.
public static void sendParam(){
try{
String val = MISControlPanel.textField.getText(); //Put whatever you want to pass as a prefix in place of "Computer"
jLabel1.setText(val);
Process p ;
p = Runtime.getRuntime().exec("cmd /c start c:\\computerQuery.bat "+val+"");
}
catch(Exception e){
e.printStackTrace();
}
}
StringBuffer sbuffer = new StringBuffer();
BufferedReader in = new BufferedReader(new InputStreamReader(p
.getInputStream()));
try {
while ((line = in.readLine()) != null) {
System.out.println(line);
//textArea.append(line);
String dn = "CN=FDCD111304,OU=Workstations,OU=SIM,OU=Accounts,DC=FL,DC=NET";
LdapName ldapName = new LdapName(dn);
String commonName = (String) ldapName.getRdn(ldapName.size() - 1).getValue();
textArea.append(String.format(" %s%n", commonName));
//textArea.setText(ComputerQuery.val);
selectedComputerFromAD.setText(commonName);
selectedComputerFromAD.setFont(new Font("Tahoma", Font.BOLD, 14));
selectedComputerFromAD.setForeground(Color.RED);
selectedComputerFromAD.setBounds(349, 84, 102, 19);
frame.getContentPane().add(selectedComputerFromAD);
}
ComputerQuery.sendParam();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (InvalidNameException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} finally
{
try {
fw.close();
}
catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
try {
in.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();

ComputerQuery.sendParam();

I have created a java gui which takes values from the user send it to python file for processing and then displays the output from the python file onto the java gui. This is working perfectly on eclipse but when i exported it into a jar file the output is not displayed. I've seen a bunch of other questions like this but they do not give a solution that would help me.
This is how i connect my python script to java.
public void connection(String name)
{
ProcessBuilder pb= new ProcessBuilder("python","recomold.py","--movie_name",name);
///System.out.println("running file");
Process process = null;
try {
process = pb.start();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
int err = 0;
try {
err = process.waitFor();
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// System.out.println("any errors?"+(err==0 ? "no" : "yes"));
/* try {
System.out.println("python output "+ output(process.getInputStream()));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}*/
try {
matches.setText(output(process.getInputStream()));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private String output(InputStream inputStream) throws IOException {
StringBuilder sb = new StringBuilder();
BufferedReader br = null;
try{
br= new BufferedReader(new InputStreamReader(inputStream));
String line = null;
while((line=br.readLine())!=null)
{
sb.append(line+"\n");
//descp.setText("<html><br/><html>");
//sb.append("\n");
}
}
finally
{
br.close();
}
return sb.toString();
}
I am creating an application that makes calls to the Hitbox API. I am trying to get the game name (listed as category_name from a list.
Thus far, I have managed to get the game name one time during the programs running stage, however when I change where to get the game name from, the program doesn't do anything. I am at a loss as to what could cause it not to send another request to the server.
public void apiConnect(){
String channel = text.getText();
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://api.hitbox.tv/media/live/" + channel);
HttpResponse response = null;
try {
response = client.execute(request);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// Get the response
BufferedReader rd = null;
try {
rd = new BufferedReader
(new InputStreamReader(response.getEntity().getContent()));
} catch (UnsupportedOperationException | IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String line = "";
try {
while ((line = rd.readLine()) != null) {
hitbox.append(line);
}
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
FileUtils.writeStringToFile(new File("hitbox.json"), hitbox.getText());
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
String game = null;
FileInputStream fileHitbox = null;
try {
fileHitbox = new FileInputStream(new File("hitbox.json"));
} catch (FileNotFoundException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
String strHitbox = null;
try {
strHitbox = IOUtils.toString(fileHitbox, "UTF-8");
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
JSONObject obj = new JSONObject(strHitbox);
JSONArray ar = obj.getJSONArray("livestream");
for (int i = 0; i < ar.length(); i++)
{
game = ar.getJSONObject(i).getString("category_name");
nameOf.setText("Game Name: " + game);
}
File hb = new File("hitbox.json");
if(hb.exists()){
hb.delete();
}
}
The above sample is the defined function, and the Get Game Name button code is below:
btnGetGameName.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
apiConnect();
}
});
Could anyone suggest what is causing it to not work after the first request, and if possible suggest a solution?
EDIT: I have found the issue. The reading of the data from the API is appended to the hitbox variable. I have thus added a snippet that clears what "hitbox" variable has when the button is pressed, thus meaning the code works without issues.
Try to consume your response after your read it to release the resource :
rd = new BufferedReader
(new InputStreamReader(response.getEntity().getContent()));
response.getEntity().consumeContent();
//Or if you have EntityUtils
EntityUtils.consume(response.getEntity());

I have this code that creates a file and saves the users input, but it keeps overwriting and I want it to save each entry a user gives. How can I do this?
File file = new File("info.txt");
BufferedWriter output = null;
try {
output = new BufferedWriter(new FileWriter(file));
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
output.write("Users pick: " + myint+ "\t");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
output.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//file writer
Change
output = new BufferedWriter(new FileWriter(file));
to
output = new BufferedWriter(new FileWriter(file,true));
for opening the file in append mode.
I've found this topic, but the code doesn't work for me... Return Windows cmd text from Java?
After pressing a button I want to execute a batch-file, for testing purposes it's just the ipconfig-command.
The cmd-output should be written into a JTextFiled, but all I get is no text...
Here the code for writing it into the JTextField:
btnLock.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
String g = "";
try {
Runtime.getRuntime().exec(new String[] {"ipconfig", g});
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Process p = null;
try {
p = Runtime.getRuntime().exec(new String[] {"ipconfig", g});
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
InputStream s = p.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(s));
String temp;
try {
while ((temp = in.readLine()) != null)
{
System.out.println(temp);
}
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
});
btnLock.setBounds(10, 68, 89, 23);
contentPane.add(btnLock);
So what do I do wrong?
It's my first project with cmd-input, so please don't get mad cause of silly mistakes I made. ;)
Thx
Try the exec command that just takes a String parameter. The following test code worked on my system (though I was only printing to console, not to textfield):
BufferedReader in = null;
try{
Process p = Runtime.getRuntime().exec("ipconfig");
InputStream s = p.getInputStream();
in = new BufferedReader(new InputStreamReader(s));
String temp;
while ((temp = in.readLine()) != null) {
System.out.println(temp);
}
} catch (Exception e){
e.printStackTrace();
} finally {
if (in != null) in.close();
}
Also your code in the original post is also using a System.out.println. As far as I'm aware, you can't print to a JTextField using System.out.println.... You'd have to use the setText method.
If I run
ipconfig ""
I get
** Error: unrecognized or incomplete command line.**
You can only run from Java, commands which work on the command line.
BTW: If you are looking for errors, you need to read the error stream.
I would Runtime.getRuntime().exec(new String[] {"ipconfig > temp.txt"}); and then just read it as a text file using a BufferedReader.
I hope this helps.
How can I mount a .dmg file through java code under OS X?
This will work (but only on OS X):
try {
String[] command = {"/usr/bin/hdiutil", "attach", "/Users/path/to/your.dmg"};
String sendback = "";
Process proc = Runtime.getRuntime().exec(command);
InputStream istr = proc.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(istr));
String str;
while ((str = br.readLine()) != null) {
sendback = sendback + str;
}
int resultCode = proc.waitFor();
br.close();
if (resultCode != 0) {
throw new Exception("failed to open system profiler");
}
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
DMGs are not executables, are apple diskimages
reference is here
thus you can't "run" it.
You can use a Process, of course. But it won't work anywhere except on a Mac.
Saying that is like asking how to run an ISO file through Java. You simply can't; it's a disk image.
