在pentaho水壶中使用功能时出错

Question

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,我收到一个错误:

org.eclipse.swt.SWTError: No more handles [MOZILLA_FIVE_HOME=''] (java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:

当我检查/home/ron/.swt/lib/linux/它有文件libswt-mozilla-gtk-3740.so

请帮我解决这个问题

Answer 1

有几个问题可能会妨碍此功能的运行.根本原因是Pentaho使用SWT功能,需要在操作系统中安装两个浏览器之一.请参阅此faq(http://www.eclipse.org/swt/faq.php#browserlinux).就我而言,我们必须通过向java命令行添加VM选项来选择是否要使用WebKitGTK(webkit)或Mozilla Firefox(mozilla):

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

在我的系统Ubuntu 14.04中,webkit浏览器在libsoup中导致错误,因此我需要将其设置为mozilla.有关参考资料,请参阅https://bugs.launchpad.net/ubuntu-gnome/+bug/1163501,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运行库.首先安装firefox:

apt-get install firefox

安装XUL runner 1.9.2因为2.0.0或更高版本被认为是不兼容的(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,关于第13行) MOZILLA_FIVE_HOME=/opt/xulrunner-1.9.2 LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}

(spoon.sh,关于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
