Getting started with Talaxie (formally Talend Open Studio)

Leave a comment

Talend Open Studio was pulled in early 2024 by Qlik.
However, the open source project has been picked up and renamed ‘Talaxie’.

Today when running the latest stable version (version 8.8.8) on a fresh Windows VM I got the following error after launching: 

Talaxie java.lang.NoClassDefFoundError: org/talend/designer/runprocess/maven/MavenJavaProcessor

The solution was to install the Java Development Kit rather than the runtime. I used: AdoptOpenJDK ‘JDK x64 v17’. After installing and running:

> java --version

openjdk 17.0.13 2024-10-15
OpenJDK Runtime Environment Temurin-17.0.13+11 (build 17.0.13+11)
OpenJDK 64-Bit Server VM Temurin-17.0.13+11 (build 17.0.13+11, mixed mode, sharing)

Talaxie opened and ran without issue.

Spago BI Installation

2 Comments

TL;DR

Installing Spago BI.

  1. First install JDK and set 3 system paths:
    • JAVA_HOME: C:\Program Files\Java\jdk<version>
    • JRE_HOME: C:\Program Files\Java\jre<version>
    • Add to PATH: ;C:\Program Files (x86)\Java\jdk<version>\bin
  2. Now run the SpagoBI installer.
  3. Run SpagoBI from Start Menu
  4. Open up a browser and enjoy.

Here are some rough notes from installing Spago BI in a somewhat blind way. (I should have probably read the docs first.)

Installation Platform:

  • Windows Server 2003 R2 x64
  • 2gb ram
  • 2 vcpus
  • XenServer 6 as host.
  1. Download the SpagoBI 4.2 installer and unzip and run.
  2. Run installer, I ticked all the options (not sure that this was the best idea).
  3. Each package selected in Step 2 has to be individually downloaded, so it takes a while.
  4. Java needs to be installed. I grabbed the JDK from Ninite.
    But the System Path Variables also need to be put in place before Spago will run. (I used the Program Files (x86) folder in the paths below).

    • JAVA_HOME: C:\Program Files\Java\jdk<version>
    • JRE_HOME: C:\Program Files\Java\jre<version>
  5. After startup, open your browser at:
    http://localhost:8080/SpagoBISpagoBI login page will appair. Log yourself as:
    – biadmin/biadmin (technical user)
    – biuser/biuser (business or functional user)
    – bidemo/bidemo (showcase user)
  6. Nothing loaded for me. Trying a reboot.
  7. Reading the console output, I possibly shouldn’t have left everything ticked in step 2, now that it has to try and load them all.
    Finally it loaded and reported the following in the console:
    INFO: Server startup in 630557 ms (that’s 10.5 minutes!)
  8. Can’t connect to sample database, I found a “start.bat” file which complained about not having access to “JAVA”. Looks like I need to add JAVA bin folder to the System Path. Restarting Spago / Tomcat
  9. This time round, a second command prompt window has also opened loading the foodmart database.
  10. Demo now appears to be working.
