 Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library.

so can somebody suggest that what is wrong?

回答1:

Pentaho do not supports the openjdk java version. Install the the Oracle/Sun java.

But anyway... Are you trying to run the kettle environment on a Ec2 instance? without X screen? If you want simply to run kettle jobs or transformations you have to use kitchen.sh or pan.sh , not spoon.sh. Spoon.sh is only to create the trans or jobs with a GUI interface.

回答2:

You have exported the wrong path of JAVA_HOME. It should be the as below:

export JAVA_HOME=/usr/lib/jvm/jre-1.6.0-openjdk.x86_64

回答3:

The issue I see here is that the yum repository for EC2 Amazon Linux AMI instance does not include any graphical binaries. These binaries include gtk and swt with gtk. You can either compile all dependencies or use another image. Since you are a newbie, I suggest you switch to an ubuntu image.

On an ubuntu image, you should be able to run apt-get to install missing dependencies:

For Java: - sudo add-apt-repository ppa:webupd8team/java for oracle java - sudo apt-get update - sudo apt-get install oracle-java8-installer

For libswt: - sudo apt-get install libswt-gtk-3-jni libswt-gtk-3-java

Another issue I can think of is that you are likely trying to run a graphical application. If that is the case, you will have to run it with a window manager like Xvnc or Xvfb.
