Hi Qin,

Here's a stage that I use to load values from a properties file.  You should 
be able to do something similar in your case:

######
# Get the next document ID
######
get-next-doc-id.stageType=Scripting
get-next-doc-id.nextStage=perl-post-doc
get-next-doc-id.failOnError=true
get-next-doc-id.language=javascript
get-next-doc-id.script=\
	var document_id;\
	var propertiesFile = new 
java.io.File(${document.get("merchant_properties")});\
	var properties = new java.util.Properties();\
	if (propertiesFile.exists()) {properties.load(new 
java.io.FileInputStream(propertiesFile));}\
    document_id = properties.getProperty("next_document_id", "10001");\
    document_id++;\
    properties.setProperty("next_document_id", document_id);\
    properties.store(new java.io.FileOutputStream(propertiesFile),null);\
    document.put("document_id", document_id);

Note that you cannot import in Javascript.  This is why you have to use the 
fully-qualified class name.


Hope this helps,

David
