Web Dynpro JAVA Application using to Upload and Download files KM of SAP Portal

[vdurgarao09]

Dear All

I have a requirement for client.Here 2 types of users available.User one upload the documents in KM using the WDJ application and same time that user can create the sub folder.once that folder is available in that upload the documents.This user is a admin type.An other user can see the document by using the WDJ application. this user is end user type and Read only.

->My question is by using the WDJ application to upload and download and creating the folders or sub folders in run time process.

I was checked this blow links but i am unable to get the information.

hi Durga rao,

File upload :

try {

          IPrivateCompView.ICtx_vn_FileDataElement element = wdContext.currentCtx_vn_FileDataElement();

      IWDResource resource = element.getCtx_va_FileResource();

      if(resource!=null){

      //To get the Current User

      IWDClientUser wdClientUser = WDClientUser.getCurrentUser();

      com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();

      com.sapportals.portal.security.usermanagement.IUser ep5User =WPUMFactory.getUserFactory().getEP5User(sapUser);

      ResourceContext resourseContext = new ResourceContext(ep5User);

      //Portal KM Path

      RID pathRID = RID.getRID("/documents/Links"); //Root Directory

      IResourceFactory resourseFactory =

      com.sapportals.wcm.repository.ResourceFactory.getInstance();

      ICollection collection = (ICollection)resourseFactory.getResource(pathRID,resourseContext);

      //Read the File

      InputStream stream = resource.read(true);

      String resourceName = resource.getResourceName();

      wdContext.currentContextElement().setFileName(resourceName);

      wdContext.currentZep_Sug_Submit_InputElement().setAttachment(resourceName);

      String resourceExtn = resource.getResourceType().getFileExtension();

      //KM Content

      Content cont = new Content(stream,"application/octet-stream",-1,"UTF-16");

      //create a file in above mentioned path in KM

      com.sapportals.wcm.repository.IResource new_resource =collection.createResource(resourceName, null, cont);

      //Get the File length

      long contentLen = new_resource.getContent().getContentLength();

      //If no data in file

      if(contentLen <= 0){

      wdComponentAPI.getMessageManager().reportException("No data in file" , true);

      }else {

      // wdComponentAPI.getMessageManager().reportMessage(IMessageUploadFile_KMComp.SF__UPLOAD,new Object[] {resourceName},true);

      }

      }else{

      element.setCtx_va_FileResource(null);

      }

      }catch (Exception e) {

      wdComponentAPI.getMessageManager().reportSuccess(""+e.getMessage());

      //wdComponentAPI.getMessageManager().reportWarning(e.printStackTrace());

  // TODO: handle exception

  }

File Download :

  IWDClientUser wdClientUser;

   try {

  wdClientUser = WDClientUser.getCurrentUser();

  IUser sapUser = wdClientUser.getSAPUser();

  com.sapportals.portal.security.usermanagement.IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);

  //Getting the Resource.........

  IResourceContext resourseContext = new ResourceContext(ep5User);

  //wdComponentAPI.getMessageManager().reportSuccess("resourseContext"+resourseContext);

  IResourceFactory resourseFactory = ResourceFactory.getInstance();

  //wdComponentAPI.getMessageManager().reportSuccess("resourseFactory"+resourseFactory);

  //path to the KM Folder ("/documents/Alice In Wonderland/alice.gif")

  RID pathRIDimg = RID.getRID(path);

  if(wdContext.currentOutputElement().getAttachment() != null){

  if((null != pathRIDimg )&&(null != resourseContext))

     {

     IResourceFactory factory = com.sapportals.wcm.repository.ResourceFactory.getInstance();

     com.sapportals.wcm.repository.IResource resource = factory.getResource(pathRIDimg, resourseContext);

     // wdComponentAPI.getMessageManager().reportSuccess("resourceimg :"+resource);

     String s = path;

     String result = s.substring(s.lastIndexOf('.')+1).trim();

     BufferedInputStream bufIn = new BufferedInputStream(resource.getContent().getInputStream());

      IWDCachedWebResource cachedWebResource = null;

      if(result.equalsIgnoreCase("xlsx")){

      cachedWebResource = WDWebResource.getWebResource(bufIn, WDWebResourceType.XLSX);

      String url = cachedWebResource.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal()) ;

      wdContext.currenDetailsElement().setDoc_link(url);

}

The above worked code worked perfectly for me.

Hi Durga Rao,

for creating a folder in the KM pragmatically use the below code,

try {

IWDClientUser WDClientUser = WDClientUser.getCurrentUser();
com.sap.security.api.IUser sapUser = WDClientUser.getSAPUser();
com.sapportals.portal.security.usermanagement.IUser epUser = WPUMFactory.getUserFactory().getEP5User(sapUser);
// wdComponentAPI.getMessageManager().reportSuccess(epUser.toString());
IResourceContext context = new ResourceContext(epUser);
RID rid = RID.getRID(“/documents”);
ICollection parent = (ICollection)ResourceFactory.getInstance().getResource(rid, context);
IResource resource = parent.createResource(“file”, null, null);
ICollection collection = parent.createCollection(“folder”, null);
wdComponentAPI.getMessageManager().reportSuccess(“uploaded”);
//ILink link = parent.createLink(″link″, ″/documents/file″, LinkType.INTERNAL, null);

} catch (ResourceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (WDUMException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UserManagementException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
