Question : How to execute batch file & .exe file using jsp servlet?I am giving input for blast in the FASTA format. After that i wants to make the sequence.FASTA file in my project folder. And I wants to execute batch file with parameters as blastp.exe file, sequence. FASTA file, database files, output file.
There is no problem in the file creation of sequence.FASTA
ERROR IN: the batch file is not execute, So the I am not able to get the output file for display.
ERROR is : java.io.FileNotFoundException: D:vaibhav_workspace.metadata.pluginsorg.eclipse.wst.server.core mp4wtpwebapps oxin-dataoutputprotein.txt (The system cannot find the file specified)
Technologies Used :JSP,Servlet,Process-builder
I have the following code as :
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out=response.getWriter();
String values=request.getParameter("t1");
ServletContext servletContext = request.getSession().getServletContext();
servletContext = request.getSession().getServletContext();
String path="//sequence.FASTA"; /*file is created in getRealPath()*/
Batch file (. BAT) problems with some folders on. I created an application in Java and put the JRE folder within the application, because some users do not have Java installed on your machine and the way I did, my application runs. JAR with the JRE that is contained in my application but I created a BAT file that contains the following command:
start "" jre8 bin javaw-jar app.jar
So I run my program in java through the file. BAT calling JRE that is inside the folder and then this JRE runs the mine. JAR and works great anywhere in windows, worked well on a USB key with this command is within. BAT (start "" jre8 bin javaw-jar app.jar).
BAT in certain folders, eg Program Files and Program Files (x86), I need this code to be able to find any directory, regardless of whether the directory has spaces in the name, symbols, numbers or anything else, because maybe people will put the application folder to another location or rename the folder, and if this happens the program will stop working? And especially do not give problems to run inside the Program Files and Program Files (x86) because the application runs everywhere except in these two folders.
I am making a ui in which i have a JTextfield and a JButton(run). I am reading values to JTextField from text file and on pressing Jbutton a Batch file runs. Now when i press the Jbutton the batch file runs showing number running, in place of number running, i want to display the JTextfield value. So i want in place of number running it should display JTextfield value running. How can i achieve it.
I get the following error when I try to run my jar file from a Batch file and CMD manually (The batch file is just set to run the jar and record any output to a text file, and open it after).

However running from Netbeans, it works perfectly; JFrame and all. I'm not sure if it's something wrong with my classpath (which I don't think is likely) or something in my code that's affecting it, here's the code:
There are multiple .CSV files (each file has multiple rows and columns). I need to fetch data from all the files and find MEDIAN of the values for each column and do further calculations. Suppose there are 3 files, i need to find the MEDIAN of column 1 in file1, MEDIAN of column 1 in file2, MEDIAN of column 1 in file3. Below code just fetch data from one file.
I'm trying to make the program read the "Entity.sql" File and then execute it to make it run in phpmyadmin. I did used a mysql connector to link netbeans to mysql and then it should used the Connection for phpmyadmin to execute the Statement (Entity.sql).The Entity.sql file contains as sql Statement:
CREATE DATABASE IF NOT EXISTS Student
The problem is that it's not working and it's giving me this error:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

In my web application i want to upload file to drop-box. I am getting file name from browser.Is it possible to upload file to drop-box with only file name.
I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){ System.out.println("Grade A, full score");} if (numberofcorrect == 2){ System.out.println("Grade B, 2 of 3 ");} if (numberofcorrect ==1) { System.out.println("Grade C, 1 of 3");} else { System.out.println("You failed the test"); }
I want to execute my jsp code to compare two dates after every 10 seconds if user enter date and current sys date are equal it will send the mail to the user automatically. Below is my jsp code
this if condition i want to check the date after every 10 seconds and when two dates are equal it will send the mail using below mail code
if(ExpcReDt.compareTo(dateStr)>0) { out.println("Expected return date is greater than current date"); } else if(ExpcReDt.compareTo(dateStr)==0)
//Main method public static void main(String args[])throws IOException{ boolean runProgram = true; Scanner keyboard = new Scanner(System.in); //runs program while runProgram is true while (runProgram){
I want to retrieve file from database which is stored with blob datatype and i am passing manually id associated with in code. Its not retrieving the file.
public class retrieve_image extends HttpServlet { /** * */ private static final long serialVersionUID = 1L; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ResultSet rs = null;
A user can dislike/like a topic. However I have to submit buttons in my jsp file, the issue is that when a user presses like/dislike it should print out on the consile line. It does that perfectly but it prints out both when it should only print out either like or dislike.
My JSP code:
<form name = "ViewTripServlet" action="ViewTripServlet" method="post">
public class Main { private static void foo(Integer a) { System.out.println("Integer"); } private static void foo(long a) { System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?
I am unable to run this java mail code, whats the error!!
public class Class1 { final String senderEmailID = "from@gmail.com"; final String senderPassword = "password"; final String emailSMTPserver = "smtp.gmail.com"; final String emailServerPort = "465"; String receiverEmailID = null;
[Code] ...
I get an error as this

I want to execute and use the Win7 Speech Recognition with Java. How can I open it?
I tried to open it with "Runtime.getRuntime().exec(" ");" but I couldn't find a command to open it. How can I use the speech recognition once I opened it with commands in Java?
I have few queries regarding compiling v/s execution of a java program. Suppose I have a Main Class which is referring to class Test which is present in JarA. Now, at compile time, this jar JarA must be present in classpath/buildpath. So, what actually is the action performed by the compiler by referring to this jar?
Now, at runtime also, this jar should be present to execute the Main class. Is this correct? If yes, then what is the action performed by JRE when it refers to this class at runtime? WOn't all the dependencies be resolved at compile time only?
