无法以Web用户身份运行oowriter

问题描述：

我在笔记本电脑上设置了一个Web服务器.我正在构建一个可通过本地网络访问的Web应用程序. 我有一个包含以下行的php文件:

I have a web server set up on my laptop. I am building a web application which I am accessing through the local network. I have a php file which contains the following lines:

$command = "/usr/bin/oowriter --invisible --convert-to pdf /var/www/hackathon/document/gaurav.doc -outdir /var/www/hackathon/pdf/"
exec($command, $output, $return_var);
print_r($output);

所以，问题是当我在终端php中运行以上代码时，它运行得很好.但是，当通过Web浏览器访问时，输出只是空的，并且没有按预期完成转换.

So, the problem is that when I run the above code in the terminal php runs perfectly. But when accessed via a web browser, output is just empty and no conversion is done as intended.

Apache错误日志显示以下几行:

Apache error log shows the following lines:

[Java框架]函数createSettingsDocument(elements.cxx)中的错误.
javaldx失败！
警告:无法从javaldx读取路径

[Java framework] Error in function createSettingsDocument (elements.cxx).
javaldx failed!
Warning: failed to read path from javaldx

我尝试了 https://wiki.archlinux.org/index中的解决方案. php/Libreoffice#Fixing_Java_Framework_Error . 但这没用.

I have tried solutions from https://wiki.archlinux.org/index.php/Libreoffice#Fixing_Java_Framework_Error. But it didn't work.

我正在使用OpenJDK 7.

I am using OpenJDK 7.

有人对如何进行这项工作有任何想法吗?

Does anybody have any idea on how to make this work?

答

还不能投票，还不能评论...所以...

Can't vote, can't comment (yet)... So...

蒂姆·爱文(Tim-Erwin)说的是真的.

What Tim-Erwin said is true.

错误实际上表明函数createSettingsDocument中的错误，这提示某些名为createSettingsDocument的函数(注意:创建设置文档)失败了....

The error actually states that Error in function createSettingsDocument which is a hint that some function named createSettingsDocument (note: create Settings Document) is failing....

这就是您的方式(或至少是我)使其正常工作:

以普通用户身份运行一次libre office并记下目录它创建的名称.
检查服务器正在运行的用户(或PHP正在运行的用户) 例如，如果您使用的是FPM等，则可能与www-data不同).
检查为此用户设置的主目录(从 /etc/passwd)
在第3步的目录中创建第1步中提到的目录
从步骤2将创建的目录的所有者更改为用户

Run libre office as a normal user once and note the directory name it creates.
Check which user the server is running (or which user PHP is running as, which might be different from www-data if you're on FPM etc...).
Check what the home directory is set to for this user (from /etc/passwd for example)
Create the directory noted in step 1 in the directory from step 3
Change owner of created directory to the user from step 2

在我的服务器上，所需的目录实际上是/var/www/libreoffice ，而在我的台式机上，该目录将是/var/www/.config/libreoffice ，因此您需要确定.

On my server the needed directory was actually /var/www/libreoffice, while in my desktop machine,the directory would of been /var/www/.config/libreoffice so you need to make sure.
