I have an ant script which does lots of stuff but I have been asked to provide jar so it can be run as an app.
I have managed to write the java code to invoke ants programatically but I am having the problem to refrence the build file from the code.
File buildFile = new File(BUILD_FILE);
where BUIlD_File is my build.xml (exists in the main directory).
When I export my proj as Runnable jar it throws an exception (File not found build.xml)
Even if I add the build.xml file into jar still it moans though if I put the build.xml file in the same folder where the jar is then it works fine. (But i dont wanna do this)
Can aynone guide me how can I make sure when I export as jar the build.xml file is added in jar and how can I refrence that file(inside jar) in my code.
Any Object running in the JVM can fetch an InputStream for any resource/file within the JAR as follows:
InputStream is = this.getClass().getResourceAsStream("yourpackage/yourfile.xml");
In your case, it sounds like build.xml isn't in a package so you should be able to use:
InputStream is = this.getClass().getResourceAsStream("build.xml");

I am struggling with opening a PDF file as a user's documentation in JavaFX program.
Code works fine whenever I open it using IDE. The problem begins when I build my program and try to open it from distributions folder.
For example, this method works, when I am using IDE:
public void helpButtonOnAction(ActionEvent actionEvent) {
File file = new File("src/main/resources/pl/com/buleek/docs.pdf");
hostServices.showDocument(file.getAbsolutePath());
}
But obviously, when I pack my program with gradle build, it is in a directory:
C:\Users\Matthew\Desktop\xxx\ProgramNameFolder\build\distributions\ProgramName\bin
And from now on, it can't see src/main/recources/pl/com/buleek/docs.pdf, because in ProgramNameFolder there are only bin with ProgramName.bat and lib folders.
Is there a way (after building distributions) to paste another folder inside my ProgramName folder, put there my docs.pdf file, and then set code like:
public void helpButtonOnAction(ActionEvent actionEvent) {
File file = new File("ProgramName/docs/docs.pdf");
hostServices.showDocument(file.getAbsolutePath());
}
Or shall I use some command to pack pdf file with my program?
Your build tool will usually place your resources in a jar. As your PDF file is already in your resources folder, it should be packaged into your application jar by default.
You can read resources from your jar file via YourClass.class.getResourceAsStream(), then write the stream to a temp file using basic Java I/O APIs, specifically the version of Files.copy(...) which takes an input stream as a parameter.
The intermediate step of extracting the PDF file from your jar and writing to a temp file in the file system is necessary because you are using host services to launch an external browser and, unlike java, the external browser will be unable to directly read resources from a jar file.
You can convert the file name of the temporary file to a URL string and show it via HostServices.showDocument(uri) as you are currently doing.
If the browser is capable of displaying PDFs (most are) then the PDF will be displayed in the browser, otherwise, the browser will usually allow the user to download the PDF to a file location of their choice on their machine and open the PDF via an external application.
I'm working with selenium. The script is in :
C:\Users\User\Desktop\Data Analytics Arg\Proyectos\datademia\Py_install\py_ejemplo.py . Venv is activated and chromedriver.exe is in C:\Users\User\Desktop\Data Analytics Arg\Proyectos\datademia\Py_install\chromedriver.exe
The script runs perfectly. Then I created an only .exe-file via terminal :
pyinstaller --add-data "chromedriver.exe;." --windowed --onefile py_ejemplo.py
Folders are created correctly (build and dist). The .exe file (py_ejemplo.exe) was created, but when I try to run it, I get this message:
I've been looking and still can't solve it... I've tried these solutions :
filenotfound
but didn't work for me...Could someone help me? I don´t know what's wrong...
Thanks in advance
I got the same problem but I was working with Firefox and geckodriver.
In my case, I copied the selenium folder from the virtual environment to the dist folder and it worked.
There are a few things you should ensure when packing a script with pyinstaller build with selenium web driver.
It may require to add driver executable when building. I.e. chromedriver.exe
It may also require to add some package files related to selenium such as getattributes.js file when building. It was required at my project.
pyinstaller will extract those files to temp folder in AppData for windows users. So in your code, your relative paths may require to be resolved with a sample function as below (if you are running your code in vs code or you are running through pyinstaller executable the paths should be resolved by function).
For item 1 and 2, you can use --add-binary and --add-data features of pyinstaller for each of them. It is also possible to do this in *.spec file with add-files list, following your first running of pyinstaller (see this explanation) I preferred command-line option as below.
pyinstaller ./app.py --onefile --noconsole --add-binary "./driver/chromedriver.exe;./driver" --add-data "C:\Users\YOUR_USER_NAME\.conda\pkgs\selenium-3.141.0-py38h2bbff1b_1000\Lib\site-packages\selenium\webdriver\remote;selenium\webdriver\remote"
For item 3, to resolve relative paths in your source code, you can use below function in related places (for example when accessing chromedriver.exe)
def resource_path(relative_path):
try:
base_path = sys._MEIPASS
except Exception:
base_path = os.path.dirname(__file__)
return os.path.join(base_path, relative_path)
Use above function once you need to access packaged executables and files in your source code. In below example, my chromedriver is inside driver folder in my workspace. But when it is accessed through pyinstaller executable, it will be extracted to temp folder in AppData, yet function will access it through sys._MEIPASS variable set by pyinstaller.
driver = webdriver.Chrome(executable_path = resource_path('./driver/chromedriver.exe'))
Hope it works.
I was trying to run a TestNG.xml file from CMD but there are no errors shown and it seems that ChromeDriver is not starting.
Note: if i go to Eclipse -> right click on testng.xml -> run as TestNG suite it will work perfectly.
Below is the message i get when executing through cmd.
The bat file contains:
java -cp "D:\Java Applications\WebDriverProject\lib*;D:\Java Applications\WebDriverProject\bin" org.testng.TestNG testng.xml
pause
The testng.xml contains:
The project structure from eclipse is:
I figured this out. First of all, how you set up the classpath environment is crucial. The very first path must be a path to your project bin folder (where the .class files are found). I will just paste what my classpath environment looks like:
set classpath=C:\eclipse-2018\ACR_Tests\bin;C:\Selenium_dependencies\*;C:\TestNG\plugins\*
Set TestNG classpath:
java -classpath %classpath% org.testng.TestNG testng.xml
Note:
I have a "Selenium dependencies" folder also added to the classpath, this is a folder containing more selenium libraries, including chromedriver.jar
Download the zipped package:
selenium-chrome-driver JAR 3.12.0
It contains the dependencies that you need.
https://jar-download.com/artifacts/org.seleniumhq.selenium/selenium-chrome-driver/3.12.0/source-code
Extract all to a folder. In my case I called it "Selenium_dependencies".
Also, for TestNG libraries I'm using 7.0.0 release which you can download here:
http://dl.bintray.com/testng-team/testng-eclipse-release/zipped/
My testng.xml is like so:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Suite">
<test thread-count="5" name="Test">
<classes>
<class name="P1.ACR_Server"/> <!-- package.class -->
</classes>
</test> <!-- Test -->
</suite> <!-- Suite -->
Also - ensure that you have client-combined.jar included on the build path.
The build path should contain these libraries:
Running your tests using Maven (Recommended way)
From your screenshot I am inferring that yours is a maven project. Maven is a build tool that helps with building java code, running tests etc., in an easy fashion. But it looks like you haven't imported your project into eclipse as a Maven project.
So if you would like to run your tests via Maven, you would need to do the following :
Remove your project from the workspace (delete it from the workspace but not from the file system). Refer here to learn how to do it.
Now remove the following files from your project folder manually :
.settings (I think this should be a folder)
.classpath
.project
If you have already setup Maven properly in your machine (Refer here to learn how to do that), you can easily clean up the eclipse related files by opening up a command prompt, using cd command to navigate into your project directory such that dir pom.xml lists the pom.xml and then running the command mvn eclipse:clean
Now refer to this StackOverFlow post to learn how to import a maven project into eclipse and import the project into eclipse.
You now have your project configured properly so that eclipse recognizes your project as a maven project. Now to run the tests from the command prompt, (refer to surefire documentation to learn how to add surefire plugin to your pom file) run mvn clean test
Running your tests from command prompt
For running your project without using any build tool, you just need to append target\test-classes and target\classes directories to your java -cp command run it. So your modified batch file can look like below
java -cp "D:\Java Applications\WebDriverProject\lib*;D:\Java Applications\WebDriverProject\bin;D:\Java Applications\WebDriverProject\target\classes;D:\Java Applications\WebDriverProject\target\test-classes" org.testng.TestNG testng.xml
pause
On a side note, please add verbose="2" or higher to the <suite> tag in your suite xml file, so that it shows you what error occurred.
Also please ensure that your testng.xml resides under src\test\resources folder (you can very well create this folder if it doesn't exist).
well try to put TestNG.jar file https://mvnrepository.com/artifact/org.testng/testng/6.7 and jcommander jar https://mvnrepository.com/artifact/com.beust/jcommander/1.7 in lib folder.
I'm making a JApplet and need to make a JAR file to connect to a .htm file with the applet tag. The simple solution I could think of was to use the tool in drjava that says "Create Jar File From Project..." but alas, it's not highlighted for some reason, so I can't do that. What I'm really looking for is either (a) an explanation as to why drjava can't turn my classes into a jar file, (b) an alternative to allow me to create this jar file, or ideally (c) both. Thanks for your help ahead of time.
I don't use Drjava, but here is how you can create a JAR file from the command line without any IDE specific complications.
Simply go to the folder/directory where your project is located. Let's say your class files are located in the bin folder. You can then use
jar cvf myapplet.jar -C bin .
The JAR is then ready to be deployed.
I have a little GWT/AppEngine Project which uses RPC. Basically I need to get some data from a XML file that resides on the server. But when I use the RPC to read the file in my server-package I am getting a AccessControlException (access denied). Any ideas what the problem is?
//JAXB powered XML Parser
public PoiList readXML() {
try {
unmarshaller = jaxbContext.createUnmarshaller();
unmarshaller.setEventHandler(new XMLValidEventHandler());
db = (PoiList) unmarshaller.unmarshal(new File("src/com/sem/server/source.xml"));
} catch (JAXBException e) {
e.printStackTrace();
}
return db;
}
java.security.AccessControlException: access denied (java.io.FilePermission \WEB-INF\classes\com\sem\server read)

I think the problem is that you're trying to read a file that is not located in your working directory. The guidlines for structuring your code in gwt apps are as follows
Under the main project directory
create the following directories:
src folder - contains production Java source
war folder - your web app; contains static resources as well as compiled output
test folder - (optional) JUnit test code would go here
Try moving the file to the war directory (for example /war/resources/myFile.xml) and then open it by
File myFile = new File(System.getProperty("user.dir") + "/resources/myFile.xml");
Usually, when you load a resource that is located in your classpath, you should't use java.io.File. Why? Because it's very much possible, that there is no real file - the classes are often packaged as a .jar file, or even loaded in a completely different way (very likely in the case of AppEngine, though I don't know the details.)
So, if you want to load it directly from your classpath, you can use:
ClassLoader classLoader =
getClass().getClassLoader(); // Or some other way to
// get the correct ClassLoader
InputStream is = classloader.getResourceAsStream("/com/sem/server/source.xml");
Then you can use the input stream in your unmarshaller.
