Java Access Bridge Windows 11
Christin Baus
Good morning all,
I work in a project that's I need to open java application by enter the link in edge, So I create two Objects the first object for open edge and enter the Link and the second object for attach Java application. But when I run second object, Attach stage don't work and give me this error:
Error - Failed to launch application - Could not initialise Java Access Bridge support - Failed to load Java Access Bridge DLL. The file could not be found in any of the following expected locations -
Application Directory:C:\Program Files\Blue Prism Limited\Blue Prism Automate\WindowsAccessBridge-64.dll
System Directory:C:\Program Files (x86)\Java\jre1.8.0_151\WindowsAccessBridge-64.dll
Windows Directory:C:\Windows\WindowsAccessBridge-64.dll
Current Directory:C:\Program Files\Blue Prism Limited\Blue Prism Automate\WindowsAccessBridge-64.dll
I try to fix this error by enable Java Access Bridge from Control Panel But doesn't work.(same error)
I try another solution to open java from Control Panel and updated it.(same error)
Note : I open C:\\ drive and go to java folder to search "WindowsAccessBridge-64.dll" file and I don't find it.
And this computer have JRE not JDK should I wanna Install new version of JDK in this computer and uninstall JRE "jre1.8.0_151" from control panel ?

First follow Ala's instructions to make sure JAB is enabled in windows. Next try using JavaMonkey or JavaFerret (if you can get hold of them online still) to test that JAB is working and there is no Windows issues prevent it from working.
Once you have validated it is on and Working but not working with your app you need to enter the dark world of manually hacking about to get JAB working for your application - which is rare but sometimes needed. There is good online Blue Prism help for JAB, there also used to be a good Java guide on the Blue Prism portal with instructions for a manual install where it is needed (not sure if it still exists) - if you can't find good instructions start by copying the missing dll to the Blue Prism Automate folder it is looking for to see if that works as a shortcut.
We have built an Assistant for working with Java application's element structure and Java locators.The Assistant provides copy-paste-able locators for each element and also allows testing locators againstselected application.
If our tools fail to pick the locator from your target application, there is always theAccess Bridge Explorer from Google that enables you to see the raw view. Please note thatAccess Bridge Explorer repository has been archived on July 27, 2022 and is no longer activelymaintained.
The Accessibility Insights for Windows can show element properties if application frameworksupports Windows UI Automation (UIA), see more at using Accessibility Insights. Then the recommendedlibrary would be RPA.Windows library.
Workaround for this situation is to initialize JavaAccessBridge library with parameter ignore_callbacks=True.Then application's element information is still accessible and any actions on those elements can be performedwith RPA.Desktop library. Keep in mind that you can still manuall refresh an element with Refresh Element.
Keyword for this purpose is Select Window. Window selection is based on the title parameter, which can begiven as a regular expressions to match the correct window. The keyword brings the window into focus and initiallyreads window's element structure.
New locator type strict has been added in rpaframework==12.5.0. Currentlyproperty values of string type have been evaluated with startsWith whichcan match several property values. With strict set in the locator string,all locator on the right side of this definition will be matched usingstrict (equal matching), example:
Keyword Get Elements still returns ContextNode objects, but with parameterjava_elements=True the keyword returns JavaElement objects instead (theystill contain reference to ContextNode object via node property, e.g.JavaObject.node).
But because application and technology support for the actions might be limited, it is alsopossible to opt for interaction elements by their coordinates by giving keyword parameteraction=False if parameter is available.
Hi. You first need to install the Java runtime environment which you can get from the oracle website. A search on google will yield you the needed result. Choose the one for your windows environment, 32 or 64bit. Install it as you would a normal application or program. Once installed, go to your command line.
Hi Bill. Sorry I forgot to mention one crucial step. Navigate to your java installation. This should be in your c:\Program Files\java\jre\bin, or something similar. press W until you get to the WindowsAccessBridge-64.dll. Copy the file to your C:\Windows\System32.
and you should be good to go. You might want to restart your pc after you copy the WindowsAccessBridge-64.dll to make sure the dll is registered to your system first, then enable your accessBridge as directed earlier. Let me know. Cheers!
Hi Vaughan. I forgot to list one more crucial step. I sent the missing procedure to Bill White but here it is in case you miss it. After you install Java, you need to navigate to your java\bin directory. This can be typically found in your C:\Program Files folder if you install Java 64Bit, or, C:\program files (X86) if you have java 32Bit installed. Here's where you have to pay particular attention.
If it is java 64Bit you have installed, copy the WindowsAccessBridge-64.dll from the Java\Jre\bin to your C:\Windos\System32 subdirectory. On the other hand, if you have java 32bit installed, then copy the WindowsAccessBridge.dll from your Java\Jre\Bin directory to your C:\Windows\SysWow64 subdirectory. After completing those steps, go to your command line and type
Hi Bill. If you downloaded the 64Bit Java Runtime environment, you should get the WindowsAccessBridge-64.dll which you should copy to C:\Windows\System32 Check if you got the 64Bit JRE downloaded, because from what you've written, you got the WindowsAccessBridge.dll instead which is the 32Bit version. Cheers!
