I am totally new to liferay.

i have created Liferay portlet in which i need to uploaded document

I used DLUtil.addFile method to upload document from webservice and from local. I also succeed in uploading it. But the problem comes when I tried to upload the document again. It shows com.liferay.portlet.documentlibrary.DuplicateFileException

my code is 

        long companyId = serviceContext.getCompanyId();
        File sampleChapter = (File) serviceContext.getAttribute("sampleChapter");
            String folderName = "Sample_Chapters";
            LMSUtil.createFolder(folderName, companyId);
            String filePath = folderName+StringPool.SLASH+fileName;
            System.out.println(filePath);
            try {
                DLStoreUtil.addFile(companyId, CompanyConstants.SYSTEM, filePath, sampleChapter);


            } catch (PortalException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (SystemException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

And the error I got is

com.liferay.portlet.documentlibrary.DuplicateFileException: D:\rajkumar\softwares\liferay\liferay-portal-6.2-ce-ga2\data\document_library\10154\0\Sample_Chapters\hello1.txt\1.0

Just from glancing at the API, you'll want to check if hasFile then updateFile else addFile

I'm performing a similar operation using a different API (DLAppServiceUtil) and given that the needed parameters are less when using DLStoreUtil, I'm going to investigate converting to this approach.

Edit: I'm not able to see the folders/directores in the Documents and Media portlet that are added through DLStoreUtil. I have verified they are uploading correctly into the /data/document_library directory. For my particular case I'll want to stick with DLAppServiceUtil due to the requirement that the files be managed via that portlet after being uploaded through my custom portlet.
