I would like to ask how i can create a bidirectional folder copy system with SFTP JSch is there any example. Like i see the code can only transfer file, I need to transfer a folder with many files from my pc to a server and the opposite.
View RepliesWhere can I learn or how can I, being the most efficient way known to do so, create a folder outside my JAR file with the java source code, this then will copy YAML documents from my JAR file to that folder, then I need to read the YAML documents some way. I'm making an addon for a game, I am using an API that allows you to make a config.yml easily, and add and read entries from it, but I've read that I need to make my own methods to be able to create additional YAML documents.
I don't exactly know what to type in google to perhaps find such a page, but I did try to find a tutorial page about this or something and couldn't.
I've partially figured out how to create a folder, but I have a problem, how can I RETURN one directory to make the folder, I don't want to make the folder in the JAR file I want to make it just outside the Jar file in the same folder that the Jar file is at.

I'm looking for a way to put a tabs on a TabPane starting from both sides on the same edge.
Imagine having 3 or 4 tabs at the top left as in the default behavior, and one at the top right for some "special" features.
Is there a way to do it? Or is something expected to exist in the future? (or not at all?)
I use the jsch libraries to create a SHH connection to a remote linux machine. In the next code, given from a tutorial of the JSCH creator, you can see it is implemented shell communication, it is a direct communication from a cmd window. You enter a command from the cmd window and you get aback the results in the cmd window.
Java Code:
String user = "username";
String host = "hostname";
ession session=jsch.getSession(user, host, 22);
String passwd = JOptionPane.showInputDialog("Enter password");
session.setPassword(passwd);
Channel channel=session.openChannel("shell");
session.connect();
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');
How i can redirect the next two lines to jTextField1 and jTextField2. To give an example i want to sen the command from the jTextField1 and to get the results from the jTextField2.
Java Code:
channel.setInputStream(System.in);
channel.setOutputStream(System.out); mh_sh_highlight_all('java');
I work on SSH for creating a external tool to manage remote OS.
I find out the JSch library and i create the java GUI project as jar application, and worked for me very well. (i am working on Netbeans ).
I introduce the JSch library with Netbeans as follow. Right click on the Project-> Properties -> Libraries ->Compile ->Add JAR/Folder.
After that i try to transform the project to applet in order to work it form web server.
I made the transformation in all the code.
When i run the applet through the Netbeans it worked for me. When i build the project to create the jar file.
I create a folder with the my.jar file, index.html, a folder named (lib) which contains the jsch-0.1.50.jar file.
Then try to run the index.html, the GUI appear but cannot connect to the remote with the SSH, and does not give any error.
I think that the problem is that my.jar cannot communicate with the jsch-0.1.50.jar.
Why the project runs trough the Netbeans an does not run when i call it from the next html code.

View Replies View RelatedI have an android device which i want to be able to switch off remotely from a console hosted on the amazon cloud.The console is a simple html button that on click sends a command to a listening server on an android device that i know its ip address.
My question,is this even possible given the huge security bleach this would present to rogue apps to be able to order actions on remote devices not started by the device owner?.
The way i know the ip is via once internet is connected on an android deice,i shall then make it announce its ip that it has been assigned by the service provider,then starting a server to accept external connections.
My theory could be wrong if what i want is not permitted.
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'm working on an application I made a few years ago. At that time I connected to a local database so my address was 'jdbc:mysql://localhost:3306/'. That database is long gone so I recreated it on one of my hosted servers but I'm a little unsure of how to connect to it. At the moment I'm trying "jdbc:mysql://www.mydomain.com:3306/" but it is giving me an access denied error.
java.sql.SQLException: Access denied for user 'myusername'@'c-[my-ip].hsd1.pa.comcast.net' (using password: YES)Every result on Google seems to use localhost so I'm having a little difficulty figuring out the correct format.
jboss 7.1.1
EJB 2.1
Though it may seem strange but in one of the application i work on still uses EJB 2.1 entity beans.While looking at the deployment log, seems like each Entity bean is registered using both remote-home and remote interfaces.
java:app/EJBApp/Entity!com.abc.remote.Remote
java:app/EJBApp/Entity!com.abc.remote.RemoteHome
Using the remote-home's JNDI lookup i was able to get the EJBObject proxy and subsequently create and use the entity.But what about the remote interface JNDI lookup ? Reason i am asking is that one needs to create an entity before use it. That said, how to use the object that i get from remote interface JNDI lookup ? Note that the class of the returned object says its "com.sun.proxy.$Proxy13" type.The JNDI location i am using "java:app/EJBApp/Entity!com.abc.remote.Remote"

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 reading input from a file that has following information:
line 1 = numbers of integers in array,
line 2 = elements in array1,
line 3 = elements in array2.
These lines constitute a test case. There are 1000 test cases in the input file.
So basically, I read the length of arrays, populate the arrays by reading from the file.
The code is below ( I have not included reading input code):
while(test_case<1000){
if (count == 1){ //count keeps track of lines in input file
vec_length = Integer.parseInt (tokenizer.nextToken());
count++;
continue;
}
if (count == 2){ //populates array1
vector1 = new int[vec_length];
for (int i = 0; i < vector1.length; i++)
vector1[i] = Integer.parseInt (tokenizer.nextToken());
count++;
continue;
}
Array2 is populated using the same as above code. However when I use the following code:
for (int i=0; i<vec_length; i++)
temp += vector1[i]*vector2[i];
I get " local variable vector1 and vector2 have not been initialized error". But both arrays have been initialized in the if{} block. Is it because initialization was local to if block?
As a studyproject I'm currently writing a class the allows me to get al fun dates (like when eastern is in a given year, what day a given date has, calculate the date of tomorrow).
While working on the following method:
public String getNextDate (int day, int month, int year) {
String nextDate;
int nextDay = getNextDay(day, month, year);
int nextMonth = getNextMonth (day, month, year);
int nextYear = getNextYear (day, month, year);
return nextDate = "the day after " + month +"-" + day + "-" + year + " is " +
nextMonth + "-" + nextDay + "-" + nextYear + ".";
}
I get a notion in my lovely IDE (eclipse) reminding me I'm not using nextDate ("The value of the local variable nextDate is not used"). But I feel I really do use nextDay here. So either I'm making a coding(style) mistake giving me this notion or I should just ignore this notion.
you can also refer this link Local variables in java?Local variables in java?To meet temporary requirements of the programmers some times..we have to create variables inside method or bock or constructor such type of variables are called as Local Variables.
----> Local variables also known as stack variables or automatic variables or temporary variables

-----> The local variables will be created while executing the block
in which we declared it and destroyed once the block completed. Hence the scope of local variables is exactly same as the block in which we declared it.

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?
