我在水壶的转换中添加了一个公式。在该公式的属性中,当我单击公式文本字段时,出现错误:

有几个问题可能会阻止此功能正常工作。根本原因是 Pentaho 使用的 SWT 功能需要安装在操作系统中的两个浏览器之一。请参阅此常见问题解答 ( http://www.eclipse.org/swt/faq.php#browserlinux )。就我而言,我们必须通过在 java 命令行中添加 VM 选项来选择是使用 WebKitGTK (webkit) 还是 Mozilla Firefox (mozilla):

-Dorg.eclipse.swt.browser.DefaultType=mozilla

在我的系统 Ubuntu 14.04 中,webkit 浏览器导致 libsoup 出错,所以我需要将其设置为 mozilla。有关参考,请参阅https://bugs.launchpad.net/ubuntu-gnome/+bug/1163501以了解 Eclipse 中的 libsoup 错误,它也使用 SWT,类似于 Pentaho。

然后,我们需要系统中存在 mozilla firefox,以及 mozilla XUL 运行程序库。先安装火狐:

apt-get install firefox

安装 XUL runner 1.9.2,因为据说 2.0.0 或更高版本不兼容(请参阅http://jira.pentaho.com/browse/PDI-8730)。

wget http://ftp.mozilla.org/pub/mozilla.org/xulrunner/nightly/2012/03/2012-03-02-03-32-11-mozilla-1.9.2/xulrunner-1.9.2.28pre.en-US.linux-x86_64.tar.bz2

tar -xjf xulrunner-1.9.2.28pre.en-US.linux-x86_64.tar.bz2

mv xulrunner /opt/xulrunner-1.9.2

使用此 VM 选项配置 xulrunner 路径:

-Dorg.eclipse.swt.browser.XULRunnerPath=/opt/xulrunner-1.9.2

我们还需要配置 LD_LIBRARY_PATH 和 MOZILLA_FIVE_HOME 指向 xulrunner :

MOZILLA_FIVE_HOME=/opt/xulrunner-1.9.2 LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}

spoon.sh 中的最终设置是:

(spoon.sh,大约第 13 行) MOZILLA_FIVE_HOME=/opt/xulrunner-1.9.2 LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}

(spoon.sh,大约第 184 行) if [ -z "$PENTAHO_DI_JAVA_OPTIONS" ]; then PENTAHO_DI_JAVA_OPTIONS="-Xmx512m -XX:MaxPermSize=256m -Dorg.eclipse.swt.browser.DefaultType=mozilla -Dorg.eclipse.swt.browser.XULRunnerPath=/opt/xulrunner-1.9.2" fi

您还可以通过替换 Kettle 的 libswt 文件夹中的 SWT jar 和 SWT-GTK jar 来解决此问题。

Diethard Steiner 在他的博客上使用 Eclipse 的 JAR 文件描述了这个简单的过程:

这样你就不必弄乱启动脚本了;但请记住,更改也将被更新覆盖。
