Thank you for the library. The 3rd party jars you added and the ones you specify in the example projects are of different version.

Edit: Seen the jar files now.

New issue: If the installed chrome driver is different from the chrome driver 104, it crashes. Is that the expected behaviour?

B4X:

Each version of ChromeDriver supports Chrome with matching major, minor, and build version numbers.

You can download other version and try:

Hi, I am not really familiar with Selenium, but this library has been very helpful so far!

I do have a question, how can I read the value/text/content of an element?

Hi, I'm trying to set adtitional arguments to Selenium Browser with
B4X:
jChrome.Initialize("jChrome", "C:\path-to-driver\", "chromedriver.exe")
jChrome.addArgument(Array As String ("--incognito"))
jChrome.Create
but it seems that it's not working, also I'm trying to open the browser with the user's google profile with this instruction but it doesn't work
B4X:
jChrome.AddArgument(Array As String ("{'user-data-dir':'C:\Users\juven\AppData\Local\Temp\scoped_dir7444_539956608\Default'}")
probably I'm not using your library as it should @tummosoft ?

From where can I get the additional jars mentioned in the post #1
B4X:
#AdditionalJar: client-combined-3.14.0.jar
#AdditionalJar: animal-sniffer-annotations-1.14.jar
#AdditionalJar: byte-buddy-1.8.15.jar
#AdditionalJar: checker-compat-qual-2.0.0.jar
#AdditionalJar: commons-codec-1.10.jar
#AdditionalJar: commons-exec-1.3.jar
#AdditionalJar: commons-logging-1.2.jar
#AdditionalJar: error_prone_annotations-2.1.3.jar
#AdditionalJar: guava-31.1-jre.jar
#AdditionalJar: httpclient-4.5.5.jar
#AdditionalJar: httpcore-4.4.9.jar
#AdditionalJar: j2objc-annotations-1.1.jar
#AdditionalJar: okhttp-3.10.0.jar
#AdditionalJar: jsr305-1.3.9.jar
#AdditionalJar: selenium-api-4.3.0.jar
#AdditionalJar: selenium-chromium-driver-4.3.0.jar
#AdditionalJar: selenium-java-3.14.0.jar
#AdditionalJar: selenium-support-4.3.0.jar
#AdditionalJar: selenium-remote-driver-4.3.0.jar
#AdditionalJar: okio-1.14.1.jar
#AdditionalJar: opentelemetry-sdk-1.16.0.jar
#AdditionalJar: opentelemetry-sdk-extension-autoconfigure-spi-1.16.0.jar

I believe that all these additional jars are required to successfully compile/run the application

I found that most of the jars are available in the jSelenium_source.7z except few listed below.

#AdditionalJar: guava-31.1-jre.jar
#AdditionalJar: opentelemetry-sdk-1.16.0.jar
#AdditionalJar: opentelemetry-sdk-extension-autoconfigure-spi-1.16.0.jar

I am getting 'No such Element' errors. I understand that we get such errors if we try to access/locate/find an HTML element inside an iFrame.
In this library is there a way to handle this ?

Before you try searching for the elements within the iframe you will have to switch Selenium focus to the iframe. Hence we need to have a method in the library to switch to iFrame.

For eg
B4X:
driver.switchTo().frame(driver.findElement(By.name("iFrameTitle")));

Basically, we can switch over the elements and handle frames in Selenium using 3 ways.
By Index
By Name or Id
By Web Element

To exit from the iFrame and then switch back to the default, we need another method

B4X:
driver.switchTo().defaultContent();

tummusoft, would you mind adding these 2 methods to the library ?

B4X:
     public  SwitchToIFrame(String element, String ByProperties) {
         String prop = ByProperties.toLowerCase();
         try {
            if (prop.contains("classname")) {
                driver.switchTo().frame( driver.findElement(By.className(element)) );
            } else if (prop.contains("id")) {
                driver.switchTo().frame( driver.findElement(By.id(element)) );
            } else if (prop.contains("cssselector")) {
                driver.switchTo().frame( driver.findElement(By.cssSelector(element)) );
            } else if (prop.contains("xpath")) {
               driver.switchTo().frame( driver.findElement(By.xpath(element)) );
            } else if (prop.contains("linktext")) {
                driver.switchTo().frame( driver.findElement(By.linkText(element)) );
            } else if (prop.contains("name")) {
                driver.switchTo().frame( driver.findElement(By.name(element)) );
            } else if (prop.contains("partiallinktext")) {
                driver.switchTo().frame( driver.findElement(By.partialLinkText(element)) );
            } else if (prop.contains("tagname")) {
                driver.switchTo().frame( driver.findElement(By.tagName(element)) );
            }           
         } catch (Exception ex) {
            BA.LogError(ex.toString());
         }
      
     }


    public void SwitchtoDefault() {
        driver.switchTo().defaultContent();     
    }

I am not a JAVA developer and I haven't used Eclipse or cradle or anything hence don't know how to compile this to a library

New update on jSelenium 2.0.1
---------------------
(1) Add the function to switch and interact with HTML frames
(2) Fix bugs with Argument options
(3) Enhance the function to export the application as an exe file.
----------------------
* Load Chrome Profiles:
jChrome.ProfilePath("c:\")
-----------
* If you want to publish your B4J project in EXE format, you need to add 2 additional options (see example below).

Options:
#PackagerProperty: AdditionalModuleInfoString = uses org.openqa.selenium.remote.session.CapabilitiesFilter;
#PackagerProperty: AdditionalModuleInfoString = uses org.openqa.selenium.remote.session.CapabilityTransform;

In the demo zip file, I have prepared a project that can be published in EXE format, if you want. In the source code folder on Github, there are also the necessary Java libraries for you to download. The source code is also uploaded to Github.

You must add this option:
jChrome.AddArgument(Array As String("--disable-notifications"))

B4X:
jChrome.Initialize("jChrome", "C:\Users\hienh\Downloads\chromedriver_win32", "chromedriver.exe")
    jChrome.AddArgument(Array As String("--disable-notifications"))
        
    jChrome.Create
