Accessing File On Remote Ubuntu Machine Using Java
Mar 3, 2015
From java running on Windows, I need to access a file on a remote Ubuntu machine. I use the following:
URL U = new URL ( "http://" + SERVER_IP + ":" + SERVER_PORT + "/" + ClsName + ".class" );
where:
SERVER_IP is the Ubuntu IP address obtained from any site that shows the IP address of the machine you are using.SERVER_PORT is the Ubuntu port where the server is listening.
Now:
Do I need to modify this code any further?Do I need to configure the Windows and/or Ubuntu machine(s) for this to work?
I am developing a web application in java(JSF 2.0 - Prime Faces). I need to do below operation. My appllication is running on WLS server. WLS is deployed on a server(say Machine-X). In my application i have a requirement , where i have to copy file from Machine-X to another Machine-Y. The Machine-Y is access restricted.
When i tried to copy the file from my app, getting no access exception. I have full control over Machine-Y. We cannot use SFTP as SFTP cannot be installed on target machine(Machine-Y). Robocopy is failing for some use cases. Is there any other way we can copy/write file from one server to other by providing userid/password in java
I have developed a code to connecting remote windows M/C from local M/C by using SSH2 (ganymed-ssh2-build209.jar) API. when I run the code its giving below error. Is there any other way to connect remote windows system using java code.
Exception.
java.io.IOException: There was a problem while talking to <host name>:22 at ch.ethz.ssh2.Connection.connect(Connection.java:642) at ch.ethz.ssh2.Connection.connect(Connection.java:460) at Connect.RemoteServer.ConnectWindowsServer.runCommand(ConnectWindowsServer.java:55) at Connect.RemoteServer.ConnectWindowsServer.main(ConnectWindowsServer.java:27) Caused by: java.net.ConnectException: Connection refused: connect
I am trying to connect a remote machine but I can't. There is a shared folder in the remote machine, when I write the path to file browser in local machine, it does not find the path specified. Both machines have successful network condition and ping each other. Also, the shared folder is opened to everyone, there should not be a permission problem, right?
I am new in java. I executed a java program using eclipse. the program contain two java file. when i try to run it using terminal in Ubuntu. Two files are not linking. it shows error. i am attaching all the data.
It shows the following error
regex2string.java:83: error: cannot find symbol str = randomstr.nextString(2000); ^ symbol: variable randomstr location: class regex2string 1 error
I have a requirement where I have to send a file from a local system to unix box(present on client side) using java code.I have developed a code that is successfully sending the file from local system to client side unix box (I am connecting to client side unix box using VPN) provided I run the code in my eclipse IDE present in local system. But when I am running the same code in the unix box it is throwing null pointer exception.Might be the unix system is not recognising the local system. Please find the code.
… and it tells me 1.7.0_51 IcedTea etc. I haven't found an OpenJDK version of Java8, so I tried the usual technique of unzipping the Oracle download into /usr/java (which I have created and given “campbell” ownership of).
campbell@xxxxx:~$ /usr/java/jdk1.8.0_05/bin/java -version bash: /usr/java/jdk1.8.0_05/bin/java: cannot execute binary file: Exec format error campbell@xxxxx:~$ /usr/java/jdk1.7.0_55/bin/java -version bash: /usr/java/jdk1.7.0_55/bin/java: No such file or directory
Same download in my home directory as I had last week. I repeated the download and got the same error. It is different from the error for Oracle Java7, which I haven't actually got installed at the moment.
I have built a Java app that uses SQLite (sqlite-jdbc-3.8.7.jar). Running the jar file on windows works as expected however, trying to run it on Ubuntu Server 14.04 has turned into quite a task!
I put together a brand new machine in VirtualBox for testing. I installed Java (sudo apt-get install default-jre) and have installed SQLite (sudo apt-get install cl-sql-sqlite3 sqlitebrowser). I created a new sub-directory within my home directory and copied over the jar file. From terminal, I then run the command: sudo java -jar ProductionView.jar and I receive a java.lang.unsatisfiedlinkerror. For troubleshooting, within the app, before making a connection to the db, I have printed out the location of where the db is to be created and it is correct (see attached pic). Is there more that needs to be configured before I can run this app on Ubuntu? I have posted the relevant code below :
(AppDatabasePath() is what is printed in the image...).
map1 is hashmap which contains the destination ip adress.When i run the above code the exit code for process (pr) is 1 and hence the tshark command is not executing properly.
I have a servlet. Users from other machines access that servlet and I want to capture the remote user's UserName and do validation over that.It's just a simple servlet and no login/password is present. I tried request.getRemoteUser(), but its of no luck.
I have several different PopupWindows that i want to access from the same fragment. I would like for each PopupWindow to be it's own java file. Here is trimmed down code from an example showPopup.java file,
showPopup.java public class showPopup { //public class showPopup extends Activity implements View.OnClickListener{ //public class showPopup extends Window { public static Context appContext; PopupWindow popupWindow; SQLiteDatabase db; EditText edSpeciesLookup,edSpeciesLookupRowid;
[code]...
How do I configure inheritance to allow showPopup() class to reside in it's own Java file and be called from another class (file)? I've reviewed several hours of online resources as well as my reference books with no productive illumination. I've tried a number of possible implementations and extensions such as "public class showPopup extends Activity implements View.OnClickListener{...", and "public class showPopup extends Window.
I have a doubt about how to design a web application which has their persistent objects in a service layer in a remote server, i mean a business application. So, once we have a web application as a client of this remote business application, how those persistent objects should be mapped in web front?
Should I either pack all jpa annotated classes into the web front application or there is another neat way to do this? I was intending in copy all persistent classes present in the remote business application into the web app package, i know it's not the best way to get what i need.
What is a more appropriate design for a web application which must get some objects from a remote business application and persist some other objects there?
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
I keep getting this error:- /opt/solr# java -v Unrecognized option: -v Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
Since a few weeks i receive windows reports with the text: "Could not create the Java virtual machine". That were not disturbing, but now i would like to play a game that based on Java, but every time I would start it, the message come and the game do not start. The game called "Edna and Harvey: The Breakout" (German: Edna bricht aus) and is developed by a german game studio called "Daedalic entertainment".
I created a program and am able to run it perfectly fine in netbeans/cmd. Then I made an .exe file with "Launch4j" and every time that I run the .exe file I get the following error: Java Virtual Machine Launcher: "A Java Exception has occurred."

I'm making a vending machine program to practice inheritance and have a few questions. My superclass is a Soda class, and I'm making subclasses like "Orange soda", "Coke", etc. My first question is, what is the point of the subclass inheriting the instance variables of the superclass? If you have to define them again is there any point in the super class having them? Here is an example of this:
My superclass:
public abstract class Soda {
public double price; public int numAvailable; public String name; public String machineCode;
[code]...
Besides not having to write the vendSoda() method again, what is the benefit of inheritance in a situation like this if you have to define all variables again? My second question is, how could I store all of the code strings from all of the different subclasses in one place? (so when the user enters a code it can search for the code entered to give the desired soda)...
I'm working in project, my theme is to develop an application management system for fingerprint and RFID card attendance machine in java programming language.
My problem i didn't find documentation in java for connecting with this device.

I am trying to build and IDE for NASM in Java for Ubuntu. There are other IDE's for NASM but they are in C or C++. So i thought i should try making one in Java. Well I am done with the GUI part.
How should i link the NASM compiler to the IDE. Or There is another way like "DEV C++ IDE" does in Windows is that it invokes the CMD and runs it in that so i could try doing something like that by invoking the TERMINAL in Ubuntu and running it in that. Does java have an API for this purpose.
I'm trying to install java_ee_sdk-6u3-jdk7-windows-x64.exe on our new Windows Server 2012 machine but the installer starts and I then get a Setup box appear that says Error: The Java(TM) Virtual Machine has aborted. I've looked in the Event Viewer and there are no messages and I've tried to get the installer to create a log file (by passing the parameter -l <loglocation>) but it doesn't seem to get that far as no log is created.
The very first time I tried to run the JavaEE install on this machine, it installed everything ok but didn't create the windows service as .NET Framework 3.5 was missing. So I uninstalled JavaEE and added in the .NET Framework 3.5 and then my problems began. I have already installed these versions of Java and JavaEE successfully on a previous Windows Server 2012 machine which had the .NET Framework 3.5 on it.
The JRE installed already on the computer is jre-6u45-windows-x64.exe and I am logged in as an administrator. I've tried uninstalling the JRE and reinstalling and also doing a registry clean using CCleaner incase there are any old references to the JRE/JavaEE but it didn't work.
