I want to upload file using RIDC functions,but before uploading it i have to check wheather it is already present on specified path in content server or not.
How i check it.

Answer 1

I tried to write a (simpler) version of my own code:
    public static Results CheckInToFolder(File f) {
        // create the binder
        DataBinder checkinDoc = idcClient.createBinder();
        // populate the binder with the parameters
        checkinDoc.putLocal("IdcService", "CHECKIN_UNIVERSAL");
        checkinDoc.putLocal("dDocTitle",
                            "Document checked in through RIDC at " +
                            new Date());
        checkinDoc.putLocal("dDocType", "Document");
        checkinDoc.putLocal("dDocAccount", "");
        checkinDoc.putLocal("dSecurityGroup", "Public");
        checkinDoc.putLocal("dCollectionID", "909964822906001607");
        // add a file
        // execute the request
        try {
            checkinDoc.addFile("primaryFile", f);
        } catch (IOException e) {
            myExecutable.logEvent("File" + f.getName() + " not found.");
            return null;
        ServiceResponse checkinResponse;
        try {
            checkinResponse = idcClient.sendRequest(userContext, checkinDoc);
            myExecutable.logEvent("Check-in successful. Size:" + f.length() + " bytes");
        catch (oracle.stellent.ridc.protocol.ServiceException e) {
                        myExecutable.logEvent("ServiceException");
                        e.printStackTrace();
                        return null;   
        catch (IdcClientException e) {
            myExecutable.logEvent("Check-in failed.");
            e.printStackTrace();
            return null;
        DataBinder checkinData;
        try {
            checkinData = checkinResponse.getResponseAsBinder();
            Results res =
                new Results(checkinData.getLocal("dID"), checkinData.getLocal("dDocName"));
            myExecutable.logEvent("Successfully got response - dID is " +
                                  res.getDID() + ", dDocName is " +
                                  res.getDDocName());
            return res;
        catch (oracle.stellent.ridc.protocol.ServiceException e) {
                        myExecutable.logEvent("ServiceException2");
                        //e.printStackTrace();
                        return null;   
        catch (IdcClientException e) {
            myExecutable.logEvent("Unable to get response.");
            e.printStackTrace();
        return null;
    }What I'm getting is this:
Mon Aug 13 14:51:29 CEST 2012 0ms: Started
Mon Aug 13 14:51:29 CEST 2012 57ms: Connection to idc://192.168.44.129:4444 successfully established.
Mon Aug 13 14:51:29 CEST 2012 102ms: Check-in successful. Size:702 bytes
Mon Aug 13 14:51:29 CEST 2012 5ms: ServiceException2
Mon Aug 13 14:51:29 CEST 2012 0ms: Finished
This means:
a) it does, indeed, return the exception (oracle.stellent.ridc.protocol.ServiceException)
b) you could use this mechanism for your code
c) it is, indeed, primaryFile.name what's being checked
I will also take a look at the other service to perform the check prior to check-in service call.
