JDBC connection works in IDE (eclipse), but not in .jar file

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.

new Rengine(...); fails without error

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

deploy already installed application on WebLogic 10.3.4 using wlfullclient.jar

I have an application named HelloWorld installed, yet not deployed. Its state is Installed, like such:
When I'm trying to deploy it on target server, say AdminServer, it results in creating a new application named helloworld.war which is deployed on AdminServer whereas the original HelloWorld app remains in Installed state. App helloworld.war is the one that is in state Active... Snapshot:
Here's the code I use to deploy the already installed app:
File warFilePath = new File("c:/helloworld.war"); // war file path on AdminServer machine
Target adminServerTarget = deployManager.getTarget("AdminServer");
WebLogicTargetModuleID targetModuleID = deployManager.createTargetModuleID(
"HelloWorld", ModuleType.WAR, adminServerTarget);
WebLogicTargetModuleID[] targetModuleIDs = new WebLogicTargetModuleID[1];
targetModuleIDs[0] = targetModuleID;
ProgressObject redeployProcessObject =
deployManager.redeploy(targetModuleIDs, warFilePath, null /*no deployment plan*/ );
There are two surprising facts, though.
First, when running this code on WebLogic versions 9.x to 10.3.3 it works great.
Second, when running this code from WLST prompt, with jython it also works great even on version 10.3.4 (I can attach the exact commands although they're the same as java except for syntactic adoptions)...
My question is, how do I make it work also on 10.3.4?

I should have thought that no one would answer this question... :)
Anyway, I found a solution. I should have used deploy instead of redeploy, with a DeploymentOptions of which name is the existing application name (HelloWorld):
ProgressObject redeployProcessObject = null;
try {
final DeploymentOptions options = new DeploymentOptions();
options.setName(applicationName);
redeployProcessObject = deployManager.deploy(
targetModuleIDs, warFilePath, null /*no deployment plan*/, options);
} catch (TargetException e) {
final String message =
String.format("Deployment of application %s on target %s failed: %s",
applicationName, allTargets, e.getMessage());
_log.error(message, e);
}
According to the docs, redeploy only replaces the current application files and plan with an updated version. Whereas deploy distributes the files (from the AdminServer) to the target(s) and starts the application.
Also, after digging deep in WebLogic's jython scripts and jars I found out that this is exactly what's done when invoking redeploy in the WLST.

Possible causes can be invoking https when the application is not configured for security

I create web service
#WebService(serviceName = "DynamipsService2")
#Stateless()
public class DynamipsService2 {
#WebMethod(operationName = "StartSession")
public static String StartSession(#WebParam(name = "key") String key) {
try {
return "100-Session started";
} catch (Exception ex) {
return null;
}
}
}
I want to test but on the page
http://localhost:8080/DynamipsService2/DynamipsService2?Tester crash bug
Error generating artifacts for the
following WSDL
http://localhost:8080/DynamipsService2/DynamipsService2?WSDL
Possible causes can be invoking https
when the application is not configured
for security
I created other Web services in the same assembly and it works.

I just experienced this problem as well. The solution for me was to use my hostname rather than localhost in the URL for the Tester.
So in my case, the following, which is what NetBeans/Glassfish did by default when I clicked Test Web Service in the NetBeans UI, did not work:
http://localhost:8080/Calculator/Calculator?Tester
However, when I paste the following into a browser, it does work:
http://david-pc:8080/Calculator/Calculator?Tester
I couldn't figure out how to change the hostname that NetBeans uses for the built-in Test dialog (nor could I cut+paste the URL from the error dialog). So I had to visually copy the URL from the error message into a browser, replacing the hostname along the way.

I had the same problem and the reason apeared in the Server's log. I'm useing Glassfish 3.1 with netBeans 7. And the error I got in the Glassfish output was:
INFO: [ERROR] com.sun.tools.javac.Main is not available in the classpath, requires Suns JDK version 5.0 or latter.
I googled a bit and it appeared to be because the glassfish server was working with the openjdk that came with ubuntu. If your problem is the same the solution I found was to remove the openjdk jre, like this:
sudo apt-get remove openjdk-6-jre
sudo apt-get autoremove
Hope this is useful.
PS: I assigned /usr/lib/jvm/java-6-sun/bin/java in the java tab at the servers configuration wizard in netBeans but don't know if that was part of the solution (I'm afraid to change it back :p)

I had the same problem with Glassfish
but it was more compilcated because of the NAT
I have GF in NAT - do MYDOMAIN and port is redirected to internal machine
the problem in GF is that it tries to connect to itself by the domain name which again redirects to inside network
(the ?wsdl works properly)
I have made temp solution adding to /etc/hosts (127.0.0.1 domainname)
be aware that it's only a temp solution
try to check if you have "localhost" in your hosts file (in windows c:/windows/system32/drivers/etc/hosts )
and ping localhost
I will add GF log - maybe someone in future will search it by google :) :)
moreover I looked GF logs there was something like ->
Connection timed out
Failed to read the WSDL document: http://MYDOMAIN:8080/MYSERVICE?WSDL, because 1) could not find the document; /2) the document could not be read; 3) the root element of the document is not <wsdl:definitions>.
failed.noservice=Could not find wsdl:service in the provided WSDL(s):
At least one WSDL with at least one service definition needs to be provided.
Failed to parse the WSDL.

Which web server do you use? If you use glassfish you can open server admin page and select Configurations===>server-config===>Security
and make Security Manager enabled

Check your domains/{YOUR_DOMAIN}/config/domain.xml
If you setup Glassfish using Eclipse, all will be done for you automatically.
Now I am surprised if I start the domain from the command line, it gave me that error, but starting Glassfish 4 from Eclipse, it is not showing any problem.

One cause could be that you don't have correctly configured the environment variable JAVA_HOME (with the correct path) and the JAVA_HOME/bin directory added to global PATH environment variable as well. For some processes the glassfish look for the classpath of the JDK installed.
Hope this help.

I had the exact same problem and it is because you have a static method, I realised after debugging for some while. Just remove static from the method and it should work.
#WebMethod(operationName = "StartSession")
public String StartSession(#WebParam(name = "key") String key) {
try {
return "100-Session started";
} catch (Exception ex) {
return null;
}
}

How to run a Mac application From Java?

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.
