Updating a document
Scenario: The document was created using DocumentManagementService’s createDocument() method and then how to update a document if we pass the updated byte[] of the same document.
The sample code would look like:
package com.sungard.bootcamp.client; import java.io.DataInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.util.HashMap; import java.util.Map; import ag.carnot.workflow.runtime.DmsUtils; import ag.carnot.workflow.runtime.Document; import ag.carnot.workflow.runtime.DocumentInfo; import ag.carnot.workflow.runtime.DocumentManagementService; import ag.carnot.workflow.runtime.ServiceFactory; import ag.carnot.workflow.runtime.ServiceFactoryLocator;
public class DMSClient {
public static void main(String[] args) {
// Obtain a reference to the ServiceFactory ServiceFactory sf = getServiceFactory(null, null, null, "motu", "motu"); DocumentManagementService dms = sf.getDocumentManagementService(); Document doc = createDoc(dms, new File("D:/SampleFile1.txt"));
System.out.println("Id of CREATED Document is : " + (doc).getId()); System.out.println("Description from CREATED Document : " + doc.getDescription()); System.out.println("Content of CREATED Document : " + new String (dms.retrieveDocumentContent(doc.getId()))); System.out.println("======================================================");
Document updatedDoc = updateDoc(dms, doc);System.out.println("Id of UPDATED Document is : "+ (updatedDoc).getId()); System.out.println("======================================================");
Document fetchedDocument = dms.getDocument(updatedDoc.getId()); System.out.println("Id of Fetched Document is : " + fetchedDocument.getId()); System.out.println("Description from Fetched Document : "+ fetchedDocument.getDescription()); System.out.println("Contents of UPDATED/Fetched Document : " + new String (dms.retrieveDocumentContent(fetchedDocument.getId())));
}
private static Document createDoc(DocumentManagementService dms, File file) {DocumentInfo documentInfo = constructDocInfo(file); try { byte[] documentContent = FileUploadUtils.getBytesFromFile(file); return (dms.createDocument("/", documentInfo, documentContent, null)); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null;
}
private static Document updateDoc(DocumentManagementService dms, Document doc) {doc.setDescription("This is the UPDATED Description of the document"); return (dms.updateDocument(doc, readFileContent(), "UTF-8", true,"TOBEREVISED", false));
}
private static byte[] readFileContent() {byte[] bytes = null; try { File file = new File("D:/SampleFile1.txt"); // File length int size = (int) file.length(); if (size > Integer.MAX_VALUE) {
System.out.println("File is to larger");} bytes = new byte[size]; DataInputStream dis = new DataInputStream(new FileInputStream(file)); int read = 0; int numRead = 0; while (read < bytes.length&& (numRead = dis.read(bytes, read, bytes.length - read)) >= 0) {
read = read + numRead;} // Ensure all the bytes have been read in if (read < bytes.length) { System.out.println("Could not completely read: "+ file.getName()); } } catch (Exception e) { e.getMessage(); } return bytes;
}
private static DocumentInfo constructDocInfo(File file) {DocumentInfo documentInfo = DmsUtils.createDocumentInfo(file.getName()); documentInfo.setContentType("text/plain"); documentInfo.setDescription("This is a txt document."); return documentInfo;
}
// Return ServiceFactoryprivate static ServiceFactory getServiceFactory(String partition, String domain, String realm, String user, String password) { Map properties = new HashMap(); properties.put("partition", partition); properties.put("domain", domain); properties.put("realm", realm); return ServiceFactoryLocator.get(user, password, properties); } }
The output of the above program is like:
Id of CREATED Document is : {jcrUuid}cbe663c6-c6fb-432b-a260-b6c4d18e597a
Description from CREATED Document : This is a txt document.
Content of CREATED Document : These are the contents of Sample File1.
======================================================
Id of UPDATED Document is : {jcrUuid}cbe663c6-c6fb-432b-a260-b6c4d18e597a
======================================================
Id of Fetched Document is : {jcrUuid}cbe663c6-c6fb-432b-a260-b6c4d18e597a
Description from Fetched Document : This is the UPDATED Description of the document
Contents of UPDATED/Fetched Document : These are the contents of Sample File1.
