Service to checkin file if it does not exist, else version the file

Question

Hi All,
From java layer I use WEBDAV and use PUT command and this command creates a new file if it does not exist, and if the file exists it versions the existing file.
I have developed a java component to unzip a folder and checkin all individual files and folders into UCM whenever a zip file is checked in.I would like similar feature in my UCM component.i.e whenever files are unzipped they should always be versioned if they exist.I use the below code,but it always creates a new file(even if file with same name exists in the same folder)
m_binder.setEnvironment(SharedObjects.getEnvironment());
m_binder.putLocal("dDocName","");
m_binder.putLocal("IsAutoNumber", "true");
m_binder.putLocal("AutoNumberPrefix", "olm_");
m_binder.putLocal("IdcService","CHECKIN_NEW");
m_binder.putLocal("dDocTitle",entityName);
m_binder.putLocal("xCollectionID",parentId);
m_binder.putLocal("dDocType", "Document");
m_binder.putLocal("dSecurityGroup","Public");
m_binder.putLocal("dDocAuthor","sysadmin");
m_binder.putLocal("dCreateDate","");
m_binder.putLocal("primaryFile", entryName);
executeService(ws, m_binder,"sysadmin",true);
So, I would like to know, if there is a service to achieve the same or is there a parameter I can add in m_binder.putLocal to achieve the same? OR am I suppose to query the UCM Database to check for existence of the file and if it exists I need to manually check out and check it in?
Thanks,

Thanks Fabian and Ryan for your feedback.
So I queried db to retrieve the ddocName and if no rows are returned my code checks in new file. But if rows are returned I checkout the file using CHECKOUT_BY_NAME and then checkin using CHECKIN_UNIVERSAL using same ddocName.
Creating/checking in new file is successful.
For existing files the checkout is successful.I also confirmed the file is checked out by querying documenthistory and ensuring a new row is created with dction = 'Check out'
But post checkout when i try to re-check using CHECKIN_UNIVERSAL command, I receive the below exception
intradoc.common.ServiceException: !csUnableToCheckIn,OLM_002103!csCheckinItemExists
at intradoc.server.ServiceRequestImplementor.buildServiceException(ServiceRequestImplementor.java:2115)
at intradoc.server.Service.buildServiceException(Service.java:2326)
at intradoc.server.Service.createServiceExceptionEx(Service.java:2320)
at intradoc.server.Service.createServiceException(Service.java:2315)
What am I missing here?
Code snippet:
m_binder.setEnvironment(SharedObjects.getEnvironment());
m_binder.putLocal("IsAutoNumber", "true");
m_binder.putLocal("AutoNumberPrefix", "olm_");
String docName = getDocname(ws, parentId, entityName);
if(docName != null && docName.equals("FILENOTFOUND")) {
System.out.println("Creating new file");
System.out.println("parentId is "+ parentId);
m_binder.putLocal("IdcService","CHECKIN_UNIVERSAL");
m_binder.putLocal("dDocName","");
m_binder.putLocal("dDocTitle",entityName);
m_binder.putLocal("xCollectionID",parentId);
m_binder.putLocal("dDocType", "Document");
m_binder.putLocal("dSecurityGroup","Public");
m_binder.putLocal("dDocAuthor","sysadmin");
m_binder.putLocal ("doFileCopy", "1");
m_binder.putLocal("dCreateDate","");
m_binder.putLocal("primaryFile", entryName);
executeService(ws, m_binder,"sysadmin",true);
System.out.println("Created file successfully");
}else{
System.out.println("Check out file");
System.out.println("parentId is "+ parentId);
m_binder.putLocal("IdcService","CHECKOUT_BY_NAME");
m_binder.putLocal("dDocName",docName);
executeService(ws, m_binder,"sysadmin",true);
System.out.println("File checked out successfully");
System.out.println("Check in file");
m_binder.putLocal("IdcService","CHECKIN_UNIVERSAL");
m_binder.putLocal("dDocName",docName);
m_binder.putLocal("dDocTitle",entityName);
m_binder.putLocal("xCollectionID",parentId);
m_binder.putLocal("dDocType", "Document");
m_binder.putLocal("dSecurityGroup","Public");
m_binder.putLocal("dDocAuthor","sysadmin");
m_binder.putLocal ("doFileCopy", "1");
m_binder.putLocal("dCreateDate","");
m_binder.putLocal("primaryFile", entryName);
executeService(ws, m_binder,"sysadmin",true);
System.out.println("Checked in file successfully");
public String getDocname(Workspace ws, String folderId, String originalName)
throws DataException,ServiceException
System.out.println("Entered getDocname");
String val = new String("FILENOTFOUND");
String sql = "select a.ddocname from documenthistory a, docmeta b, documents d " +
"where a.did = b.did and a.did = d.did and d.DORIGINALNAME = '" + originalName +
"' and b.xcollectionid = '" + folderId + "'";
System.out.println("sql query is : " + sql);
ResultSet rs = ws.createResultSetSQL(sql);
if(rs == null) {
System.out.println("Resultset for getDocname is empty");
throw new ServiceException("Resultset for getDocname is empty");
DataResultSet result = new DataResultSet();
result.copy(rs);
if(result.getNumRows() >= 1) {
result.first();
val = result.getStringValue(0);
System.out.println("ddocname is :" + val);
return val;
else {
System.out.println("FILENOTFOUND");
return val;
