Oracle UCM -Custom Service创建

Question

I have a requirement where in i need to merge some contents(Documents) into a Single Document and send it back to the Front end ADF Application for a user to download it. I 'm trying to create a custom service which will accept the parameters in the form of an Array List -something like ["Doc,ContentID1,ContentID 2","Document,ContentID3,ContentID4"],Where DOc and Document will be the name of the merged documents and ContentID1,ContentID2 will be the contents to be merged and form a new document "Doc" and ContentID3,ContentID4 will be merged and form a new document "Document" and both these documents are sent back to the application.

If I create a custom service where can I define what type of parameters will it accept. Any help/pointers is appreciated. TIA

Answer 1

Parameters for services are similar to standard html GET parameters, ie they are just strings (so the answer is no, you can't "define what type of parameters will it accept" - they are always strings). Once a service is called all parameters are available in m_binder.

In your case call like:

http://<ucm_host>/<ucm_instance>/idcplg?IdcService=MEGE_DOCUMENTS&merge1=docName1,contentId1,contentId2&merge2=docName2,contentId1,contentId2

will run custom service MEGE_DOCUMENTS with 2 parameters - merge1 and merge2 - in m_binder. You may get them like this:

String parameter1 = m_binder.getLocal("merge1");
String parameter2 = m_binder.getLocal("merge2");

after that parameter1 will have value " docName1,contentId1,contentId2 " and parameter2 - " docName2,contentId1,contentId2 "

So, if this service is supposed to be run independently (eg from browser / as a separate service) - I'm afraid you'll have to iterate through parameters. Like this, for example (I know it is ugly, but it's all you can do in your situation):

Map<String, String> params = new HashMap<String,String>(); 
String prefix = "merge"; 
int index = 1; 
boolean hasMoreParams = true; 

while(hasMoreParams) { 
    String paramName = prefix + index;
    if(m_binder.m_localData.containsKey(paramName)) {
        String paramValue = m_binder.getLocal(paramName); 
        params.put(paramName, paramValue); 
        index++; 
    } else { 
        hasMoreParams = false; 
    } 
}

---

In case your service will be used by other services/filters (ie called from java code only ) you may put any java object (eg HashMap) in binder's local data before service call and then use it:

m_binder.m_localData.put(<Object>, <Object>);

Do not mix up m_localData with m_binder.putLocal(). m_localData is a Property variable (an extension of HashTable). putLocal() is a method which have only one String parameter.
