I then made a change in the TLD file adding 1 more tag to the TLD. I tried changing these and i got my JSP working with the above lines. When i entered the URL's for the DTD's in a browswer they are found. CompileException: C:\jakarta-tomcat-3.3a\webapps\taglib\time.jsp(0,0) Unable to open taglibrary WEB-INF/exampleTags.tld : Parse Error in the tag library descriptor: External entity not found: "". Here is the error im getting for the browser: Im having trouble getting a very simple taglibary working. 1.7K Training / Learning / Certification.165.3K Java EE (Java Enterprise Edition).7.9K Oracle Database Express Edition (XE).3.8K Java and JavaScript in the Database.You can enable it by setting the enviroment variable ETA_LISTEN to 0.0.0.0, and set ETA_IP and ETA_PORT to the IP address and the port that you want to use for remote connection to this computer. Remote access is disabled by default to keep your computer safe.In the ETA GUI you can then specify the IP address and port number of the computer running the backend, which can just be localhost:5678 if you run backend and frontend on the same PC with the default settings.The computer which runs the ETA Backend will do the number crunching and it might be advantageous to run it on the computer which has the timetag files so the (potentially large) files do not have to be copied around. If problem occurs, try pip install -upgrade again to upgrade each ETA dependencies. In order to analyze your own time tag file, you can drag a recipe ( recipe_name.eta) onto the main screen to load it, specify filename in the variables, and then click "Run" button besides the Display Panel you want to execute.Click the "Run" besides the Display Panel you want to execute to see the results. After launching the ETA GUI, click New and then click Simulation, it will load a simulation recipe which can run without any actual timetag.Open a Web browser window and type the ETA URL on the address bar to launch the GUI.When the Backend is started, it should look lile.Set C:\Users\\Anaconda3\Scripts\activate.bat python -m etabackend Create a text file and add the following, adjusting the path to your Anaconda installation, then save save as a. Optionally, you can create a short cut for faster launching. This will create a conda environment for ETA with python newer than 3.9.Īctivate the ETA conda envronment, and type python -m etabackend to start the ETA Backend. Open the Anaconda promt and type the following lines.After installation, type python3 -m etabackend to start ETA Backend.įor Anaconda/Miniconda in separate environment:.Please note that on certian platforms you should put python instead of python3. If you use offical Python installation, type python3 -m pip install etabackend -upgrade to install ETA.Install as a Python package For offical Python distribution: Check the Github Releases ( ) for further information about whether the recipes should be updated.If you prefrer to do it manually you can run the extracted ETA-Setup-x.x.x.exe like in a fresh installation. It will then be automatically installed when the program is closed. ETA will attempt to download a new release if one exists at program start.Click the ETA Backend (icon with black background) to start the backend first, and then click ETA (icon with white background) to launch the GUI. After installation, two icons will be created on the desktop.(It is recommended to temporarlily disable realtime thread scanning on your anti-virus software to accelerate the file unzipping.) Run the extracted ETA-Setup-x.x.x.exe to install ETA GUI and ETA Backend.You will need only the ETA_Install-win64.zip file for the installer of ETA GUI and ETA Backend. You can download ETA from Github Releases ( ).Currently, Windows 圆8_64 binary builds are provided on Github. You can install ETA GUI and ETA Backend as a standalone program. Install as a standalone program (Windows-only) We recommend users to install ETA as a standalone program on Windows, and as a Python package on other platforms. If you transfered the time tag files to your own computer for evaluation, make sure you are running both the GUI and the backend locally.Ĭurrently, ETA (>=0.7.0) has been tested on 64-bit versions of Microsoft Windows 7/10/11, Ubuntu 20.04/22.04 and Mac OS 10.15 with Python >3.6, but it may also work nicely on other platforms. The GUI, however, can be used from anywhere with a morden browser, and network access to the data aquisition computer. Since correlators are typically close to the setup and require a fast interface for data transfer, it is advisable to run the backend on the computer controlling the correlator. We chose to separate the program in this way to allow remote analysis of time tags. ETA is comprised of two parts communicating via websocket: the GUI and the backend.
