使用 JODConverter 將 Microsoft Office 文件轉換成 PDF

使用版本：
JODConverter v2.2.2,
LibreOffice v3.5
JODConverter 需要在本機電腦中安裝 LibreOffice (OpenOffice 也可)，本處以 LibreOffice 為範例


可轉換類型：
*.doc,
*.ppt,
*.xls,
*.docx,
*.pptx,
*.xlsx


使用教學：

Step1: 安裝 LibreOffice

Step2: 啟動 LibreOffice Service
   1. cd C:\Program Files\LibreOffice 3.5\program
   2. soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

Step3: 將 JODConverter library 裡的 jar 檔放進專案

完成以上動作後，即可開始測試下面範例程式

使用方式，可傳入檔案完整路徑，或檔案的 File 物件，如

OfficePDFUtil officePDFUtil = new OfficePDFUtil();

officePDFUtil.convert("test.doc", "doc.pdf");

        } finally {

                throw e;

            }

        }

    }

RedHat Linux 上安裝 RPM 版本 LibreOffice 3.5

1. 解壓縮

tar zxvf [安裝檔名]

例如:

tar zxvf LibO_3.5.2_Linux_x86-64_install-rpm_en-US.tar.gz

2. 解壓縮的目錄會位於壓縮檔的相同路徑下

例如:

LibO_3.5.2_Linux_x86-64_install-rpm_en-US.tar.gz ← 在 /user/home

LibO_3.5.2rc2_Linux_x86-64_install-rpm_en-US ← 也會在 /user/home

進入解完壓縮後的目錄

cd LibO_3.5.2rc2_Linux_x86-64_install-rpm_en-US/RPMS

並執行下列命令 (必須為 root 帳號)

rpm -Uvh *.rpm

3. 安裝完畢後的路徑

/opt/libreoffice3.5/program

4. 啟動 Service 指令(背景執行)

/usr/bin/nohup /opt/libreoffice3.5/program/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard 0</dev/null 1>/dev/null 2>/dev/null &

5. shell 檔案如下 (在 server 上啟動 Libre Office 的服務)

<startup_soffice.sh>

#!/bin/bash

# Update source files from Subversion and build them

#

# History

# 2012.04.20 GUC-Kaohung

# create this file

LibreOffice_HOME=/opt/libreoffice3.5/program/soffice.bin

# find tomcat PID

tomcatpid=`ps -ef | grep "$LibreOffice_HOME" | grep -v grep | awk '{print $2}'`

if [ -n "$tomcatpid" ]; then

kill -9 $tomcatpid

echo "LibreOffice3.5 service is stopped."

fi

/usr/bin/nohup /opt/libreoffice3.5/program/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard 0</dev/null 1>/dev/null 2>/dev/null &

echo "LibreOffice3.5 service is started."

<shutdown_soffice.sh>

#!/bin/bash

# Update source files from Subversion and build them

#

# History

# 2012.04.20 GUC-Kaohung

# create this file

LibreOffice_HOME=/opt/libreoffice3.5/program/soffice.bin

# find tomcat PID

tomcatpid=`ps -ef | grep "$LibreOffice_HOME" | grep -v grep | awk '{print $2}'`

if [ -n "$tomcatpid" ]; then

kill -9 $tomcatpid

echo "LibreOffice3.5 service is stopped."

fi
