I already install jco3 for linux.
I'm using ubuntu 16.04 x86_64 and java-8-oracle
as the documentation said, i need to add LD_LIBRARY_PATH and CLASSPATH to jco directory.
export LD_LIBRARY_PATH=/home/zain/sapjco
export CLASSPATH=/home/zain/sapjco/sapjco3.jar
then create simple jco connection test
import com.sap.conn.jco.*;
public class testjco {
public static void main(String[] args) {
JCO.Client mConnection;
try {
mConnection = JCO.createClient("301", // SAP client
"somecoolguy", // userid
"****", // password
"EN", // language
"XXX", // application server host name
"00"); // system number
mConnection.connect();
System.out.println(mConnection.getAttributes());
mConnection.disconnect();
} catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
}
}
but when i run my project i got error
error: package com.sap.conn.jco does not exist
is there any particular step i missed?
I don't know if you've already done this but:
export LD_LIBRARY_PATH=/home/zain/sapjco
export CLASSPATH=/home/zain/sapjco/sapjco3.jar
only work in the current bash instance, which means that if you ever close that terminal window then that export path will be gone. One way to keep it is to add it to your ~/.profile
then you can just run this source ~/.bashrc in order to refresh your bash window.
Don't know if that helped since I have never coded Java in Ubuntu, only on Mac with Eclipse/Idea. Anyways, if that's not how to do it, then there's a problem with the way you imported your sapjco3.jar to your project.
You also need to use your CLASSPATH environment variable and pass it as classpath argument to your JVM instance that shall run your project.
But I don't think that you are really at the step of running your project, you must be already failing to compile your class testjco. (By the way, I recommend to follow the common Java naming conventions and let all class names start with an uppercase letter.)
You are importing the package com.sap.conn.jco which belongs to the SAP Java Connector 3.0 (sapjco3.jar), but in your code you use the JCo API from package com.sap.mw.jco of the outdated SAP Java Connector 2.0/2.1 (sapjco.jar). That does not work and cannot be compiled.

I've set up a jep project within IntelliJ-IDEA, and keep getting this error when I run my code:
Exception in thread "main" jep.JepException: <class 'ModuleNotFoundError'>: No module named 'spacy'
at src/main/python\nlq_wrapper.<module>(nlq_wrapper.py:2)
at <string>.<module>(<string>:1)

Even though spacy is included in my interpreter SDK packages.
Another weird thing is that the Python terminal within IntelliJ-IDEA can find and use spacy.
But when I try and run the program from the terminal or from my system's CLI, it can't find the modules and I get the same error.
Is there some extra configuration for jep that I need to do to be able to use other python modules with it? or is jep just not compatible with other modules?
EDIT
For further clarification here are the run configurations for Java and Python.
Java run configuration:
Python run configuration:
I fixed it thru this code you call before JEP interpreter:
PyConfig pyConfig = new PyConfig();
pyConfig.setPythonHome("/home/user/[NEW_PYTHON_HOME]/");
try {
MainInterpreter.setInitParams(pyConfig);
} catch (JepException e) {
e.printStackTrace();
}

Yesterday I installed a new version of Netbeans (NetBeans IDE 8.2 (Build 201705191307)) and since then I can't connect to my gitlab repo (fails on trying to clone project). Credentials are fine, work on other computers and systems and I logged in over the browser(my first thought was that I tried a wrong password and banned my IP).
I use Windows 10, Java 1.8.0_31.
EDIT: Access to gitlab worked on an older version of NetBeans (not sure which one was it but above 8.0)
Updated JDK to 1.8.0_171 - still no success.
Also this was found in IDE log

The stack trace shows that the code failed when trying to create a symbolic link by calling Files.createSymbolicLink(). To do that on Windows 10 you must run with Administrator rights, or you need to have the right to create a symbolic link, so the true solution to your problem is to set appropriate User Account Control (UAC). This is the case even if you created the file or directory to which you want to add a symbolic link.
If you open a Command Prompt window, create a directory and then try to add a symbolic link it will fail with the error "You do not have sufficient privilege to perform this operation", but if you do the same thing when selecting Run as Administrator before opening a Command Prompt window it works fine:
The same principles apply when creating a symbolic link in a Java application on Windows 10, and again the proper solution is to set UAC appropriately. However, there is an easy workaround solution: just as you can open a Command Prompt window as an administrator, you can also run NetBeans as an administrator:
Once you do that the java.lang.InternalError should be gone.
You can run the trivial Java application below to confirm that admin rights are needed when creating a symbolic link under Windows 10. The application fails with a FileSystemException ("A required privilege is not held by the client.") when calling Files.createSymbolicLink() from NetBeans if it is started normally, but works fine when NetBeans is Run as administrator.
public class SymLink {
public static void main(String... args) throws IOException {
String originName = "c:\\ThisIsJunk";
String targetName = originName + "SymLnk";
Path origin = Files.createDirectories(Paths.get(originName));
Path target = Paths.get(targetName);
try {
Files.delete(target);
} catch (NoSuchFileException e) {
}
try {
Path symLink = Files.createSymbolicLink(target, origin);
System.out.println("Symbolic link created: " + symLink.toString());
} catch (AccessDeniedException e) {
e.printStackTrace();
}
}
}
After having the same issue mentioned above while running in Administrator Mode, I noticed I had Netbeans running in Windows 8 Compatibility mode. Unchecking compatibility mode, I was then able to connect to the Github repository.
I'm really looking at a mystery here. I created a Java program in Eclipse and established a JDBC connection. The code is the following:
import java.sql.*;
public class Login {
public static void main(String[] args) {
try {
// Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection connection = DriverManager
.getConnection("jdbc:sqlserver://localhost;databaseName=testdb; integratedSecurity=true;");
//adding port 1433 doesn't make a difference
System.out.println("Connection successful");
Statement st = connection.createStatement();
ResultSet rs = st.executeQuery("select * from testtable");
while (rs.next()) {
line = rs.getString(2);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
When I'm running it within eclipse, everything's fine. The database and tables are good, library and authentication in the Java Built Path are set and I get the result I want, namely "Hello World", which is a string in the selected table.
But creating an executable JAR file and running it throws the exception "This driver is not configured for integrated authentication". It does not even connect, so even if there was an error in the database it wouldn't matter at this point.
Even more confusing is the fact, that some weeks earlier, I also created an executable JAR file and it worked!
OS: Windows Vista Home Premium x86
JDBC driver location: "C:\sqljdbc_4.0\enu\sqljdbc4.jar"
Native library location: "C:\sqljdbc_4.0\enu\auth\x86"
Java version: Java 7 Update 17 and JDK 7 Update 17
Previousely, I used Update 21, but I changed back to check if the driver could be the reason.
So, any suggestions? I'd be very grateful!
Check the runtime classpath of eclipse, then try to create a system level "CLASSPATH" variable and add the same path. Once the variable is set, execute it in new command prompt or reload the environment variables
Make sure your executable jar has the dependency in MANIFEST.MF for all the necessary jars (along with MainClass)
Finally, It is always a practice in Java to make the first alphabet in Capital ("Login" instead of "login")
Actual problem is that if you run your project from eclipse, it will automatically add run arguments that are defined in run/run config//arguments, so you run your program with properly set path to sqljdbc_auth.dll. But if you export your application to .jar file and just run it, you will get these errors cause there is no correct classpath to auth file.
So, if you run your app from command line with proper arguments, it should be working.
I'm trying to set up JRI with Eclipse on a Windows 7 x64 system. I tried it once on my Laptop and it worked. Now on my Desktop it fails although everything of the R, rJava and JRI installation is exactly the same.
I set the JRI and R Paths correctly to:
C:\Program Files\R\R-2.15.1\library\rJava\jri;C:\Program Files\R\R-2.15.1\bin\x64
Also I set R_DOC_DIR etc in Eclipse.
Every time I try to run new Rengine(...); it fails without any error or exception. Debugging revealed an: <terminated, exit value: 10>C:\Program Files\Java\jre6\bin\javaw.exe (01.10.2012 18:00:31)
Is there anything I can try? It really bothers me that it works an my Laptop but not on my Workstation despite the same settings everywhere.
Edit: The code that is used to get the Rengine object.
public static Rengine getRengine(){
if (re == null) createRengine();
return re;
}
public static void createRengine(){
if (re!=null) return;
try{
if (!Rengine.versionCheck()) {
System.err.println("** Version mismatch **");
System.exit(1);
}
String[] arguments = {"--save"};
re=new Rengine(arguments, false, null);
if (!re.waitForR()) {
System.out.println("Cannot load R");
return;
}
}
catch (Exception e){
e.printStackTrace();
}
}
Edit: The last time i tried it i got an errormessage (creating of the REngine worked, this happened never before), R was missing a registryentry. After installing R 2.15.1 again it suddenly worked. Now after a restart it's the same like before. The program crashes at the creation of the REngine.
I was having the exact same problem. It turns out I had unchecked the box that asks to make a registry entry with the R version number. Once I let the installer run with that box checked, it seemed to work.
I would make sure your regedit looks like this:
Next up: getting this working in a portable way...
I am using R 3.2.2 and eclipse Mars on Windows 10 x64.
I faced the described issue today and tried around a bit. Finally, I found the root cause in the build path. Please check whether the following conditions are fulfilled:
1.) The following Java libraries from the JIRI folder on your hard disk shall be included as (user) libraries:
JIRI.jar
REngine.jar
JRIEngine.jar
2.) The native library jiri.dll is located in the subfolder "i386" for x86, whereas for x64 it is available in the subfolder "x64". The relevant one shall be added as separate native library location to the Java Build Path of the eclipse project. Otherwise, the file may not be considered as it is not located in the main JIRI folder.
Best regards

I tried the code below to run a stand-alone utility app I created from Apple script but, I get a No File or Directory Exists error.
I put identical copies (for testing) in the project, dist, parent directories but, it didn't help.
So, my questions are:
Is my call to run the app bad (perhaps because it's not a Windows exe)?
How to run a mac app from java?
Thanks
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
Runtime r=Runtime.getRuntime();
Process p=null;
String s="MyLineInInput.app";
try {
p = r.exec(s);
} catch (IOException ex) {
Logger.getLogger(AudioSwitcherView.class.getName()).log(Level.SEVERE, null, ex);
}
}
A Mac App Bunde is not an executable file, it's a folder with a special structure. It can be opened using the open command, passing the App Bundle path as an argument: open MyLineInInput.app.
EDIT:
Even better would be using Desktop.getDesktop().open(new File("MyLineInInput.app"));
I used the Runtime.getRuntime().exec() method with the open command mentioned in the selected answer. I didn't use Desktop.getDesktop().open() since it unwantedly opened a terminal in my case and I didn't want to create an extra File object.
Process process = Runtime.getRuntime().exec("open /System/Applications/Books.app");
Reason for adding '/System':
It seems we need to use the /System prefix for System apps. For user-installed apps, that's not required, and it can be like /Applications/Appium.app.
To answer #Pantelis Sopasakis' issue that I also faced initially -
I get the error message: java.lang.IllegalArgumentException: The file: >/Applications/Microsoft Office 2011/Microsoft\ Excel.app doesn't exist.
In this case, it could be simply due to not escaping the space characters in the path.
