How to get an overview of a document within the framework in my application

Hello

I have an ADF project that integrates with Cloud Computing service for the oracle document

I can download, download, create folder, delete the folder and file list version using my ADF application.

My problem is one which is how can I preview the document on cloud of in my adf page. I don't want to download the file, I want to see it.

I tried to accomplish this task, but I faced this error

but this error occurs

java.lang.RuntimeException: failed: HTTP error code: 400

State Info: Bad Request

What follows is the source of the page

  <af:panelStretchLayout id="psl1" binding="#{backingBeanScope.backing_WEBINF_fragments_previewDoc.psl1}"
                           dimensionsFrom="parent" topHeight="250px" endWidth="50px">
        <f:facet name="center">
            <af:panelBox text="Preview Area" id="pb4"
                         binding="#{backingBeanScope.backing_WEBINF_fragments_previewDoc.pb4}" type="stretch"
                         styleClass="AFStretchWidth">
                <f:facet name="toolbar"/>
                <af:inlineFrame id="if1" source="#{cloud.frameSource}" partialTriggers="b1"/>
              
               
            </af:panelBox>
        </f:facet>
        <f:facet name="top">
    <af:panelBox text="Preview Uploaded File By File ID" id="pb2">
                    <f:facet name="toolbar"/>
                        <af:inputText label="Enter File Id" id="it1"                                     
                                      value="#{cloud.fileId}" placeholder="Copy and paste the file id here"/>
                        <af:button text="Preview" id="b1"                                 
                                   action="#{cloud.viewFileAction}"/>
                   
                </af:panelBox>
            </af:panelGroupLayout>

When the user click on the Preview button, the document should be included as part of the line

It is the method that returns the string url of the document. To be honest, as this method is not mine, I took this post How to integrate oracle doucument cloud service at my request

And I add a few modifications to this

public String getFileUrl() {


        //Read properties file to get host, port, contextroot, username, password
        try {
            m_protocol = SamplesUtils.readConfigFileValue("protocol", m_cfgFilePath);
            m_host = SamplesUtils.readConfigFileValue("host", m_cfgFilePath);
            m_username = SamplesUtils.readConfigFileValue("username", m_cfgFilePath);
            m_password = SamplesUtils.readConfigFileValue("password", m_cfgFilePath);
            m_contextroot = SamplesUtils.readConfigFileValue("contextroot", m_cfgFilePath);
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println(e.getMessage());
            return;
        }


        try {
            Client client = SamplesUtils.getClient();
            String resourceStr = m_protocol + "://" + m_host + "/" + m_contextroot;
            System.out.println("Calling GET on " + resourceStr + m_restresource);
            WebResource webResource = client.resource(resourceStr + m_restresource);
            String authString = m_username + ":" + m_password;


            try {
                authString = DatatypeConverter.printBase64Binary(authString.getBytes("UTF-8"));
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }


            ClientResponse response =
                webResource.header("Authorization", "Basic " + authString).post(ClientResponse.class);         
          
            if (response.getStatus() != 200) {
                throw new RuntimeException("Failed : HTTP error code: " + response.getStatus() + "\nStatus Info: " +
                                           response.getStatusInfo());
            }         
            Item item = response.getEntity(Item.class);


            //To print out all folder and item info, just call toString on the Object. A little verbose, however.
            System.out.println(item);


            //Print out individual top level variables of FolderItems object
            System.out.println("*************************************************************************");
            System.out.println("Name: " + item.getName());
            System.out.println("Owned by: " + item.getOwnedBy().getDisplayName());
            System.out.println("Created by: " + item.getCreatedBy().getDisplayName());
            System.out.println("Modified time: " + item.getModifiedTime());
            System.out.println("Id: " + item.getId());
            System.out.println("Parent Id: " + item.getParentID());
            System.out.println("ErrorCode: " + item.getErrorCode());
            System.out.println("Size in bytes: " + item.getSize());
            System.out.println("Version: " + item.getVersion());
            System.out.println("*************************************************************************");




        } catch (Exception e) {
            e.printStackTrace();
        }
  return resourceStr+"applinks/file/"+item.getId()
    }

You have a bad request. You are not passing in the attributes assignerUser and role on the URL that is required to create Applink. You pass to one these two parameters in like a load of JSON or URL params.

JsonPayload String = "{\"assignedUser\":\. "" + m_assignedUser + "\",\"role\":\ " » » + m_role + « \ »} » ;

Or on the URL:

/API/1.1/applinks/file/DCA4BBA0908AE2F497832BC2T0000DEFAULT00000000?assignedUser=someusername&role=Downloader

Example below shows passing as a string in JSON format. I also atrtached the POJO AppLink.java I use entitled it the answer, so the values are accessed.


/* ********************************************************************************************************************
