----------------------------下面针对cBPM

[root@localhost html]# gedit /root/.bashrc
[root@localhost html]# gedit /etc/profile
末尾添加：
---------------------------------
export WF_HOME=/etc/nginx/html
export CRITERIA_HOME=/etc/nginx/html
---------------------------------

[root@localhost criteria-lin]# gedit ./src/Criteria/Criteria.WorkflowEngine/WAPI/WAPI.cpp
-------------------------
使用绝对路径, 如下。因为代码里面不能解析 ${CRITERIA_HOME}。权宜之计。
       //ztg alter path
       //String sWfHome = System::getEnvironmentVariable("${CRITERIA_HOME}");
       //String sWfHome = "/opt/cBPM/criteria-lin/bin/Criteria/Debug/Tools.Executor";
       String sWfHome = "/etc/nginx/html";

   //ztg alter path
   //string sDirectory = bOS::CoreSystem::System::expandEnvironmentStrings ("${WF_HOME}");
   //String sDirectory = "/opt/cBPM/criteria-lin/bin/Criteria/Debug/Tools.Executor";
   String sDirectory = "/etc/nginx/html";
-------------------------

[root@localhost html]# gedit database/Criteria.xml
-------------------------
使用绝对路径, 如下。因为代码里面不能解析 ${CRITERIA_HOME}。权宜之计。
/etc/nginx/html/database/processTemplate
而非：
${CRITERIA_HOME}/database/processTemplate
-------------------------

[root@localhost html]# gedit database/processTemplate/TestNotePad.xml
-------------------------
?NoteResult?@gedit@%FileName1%
修改为
?NoteResult?@touch@%FileName1%

FileName1 ——> /opt/cBPM/criteria-lin/bin/Criteria/Debug/Tools.Executor/notepad.txt
-------------------------

[root@localhost html]# cp /opt/cBPM/criteria-lin/bin/Criteria/Debug/Tools.Executor/executer .
[root@localhost html]# cp -a /opt/cBPM/criteria-lin/bin/Criteria/Debug/Tools.Executor/database/ .

[root@localhost html]# export WF_HOME=/etc/nginx/html; export CRITERIA_HOME=/etc/nginx/html

[root@localhost html]# spawn-fcgi -a 127.0.0.1 -p 8088 -f /etc/nginx/html/executer

[root@localhost html]# ./executer TestNotePad

[root@localhost html]# lsof executer
