Hi All,
I have customized the Webtop 6.5 to cater to my needs of sending and recieving files through web services. As a result i obtain zip files from a web service of mine. The zip file contain documents ( for example .txt or .doc files). I have my code that saves documents from web services inside the repository (inside the cabinets which are chosen by the user).
But now i have this requirement to unzip the files which i recieve and save it inside the CMS.
public void createFile(byte [] fileReta,String path) throws Exception { System.out.println (" Step 1"); String filenametoberetrieved = FreewayDashboard.filenamos ; System.out.println (" Step 2"); filenametoberetrieved.trim();System.out.println (" Step 3 ::" + filenametoberetrieved.trim()); createSessionManager();System.out.println (" Step 4"); mySession = m_sessionManager.getSession(rname); System.out.println (" Step 5 ::" + mySession); document = (IDfDocument) mySession.newObject("dm_document"); System.out.println (" Step 6 ::" + document.toString()); //document.setObjectName(filenametoberetrieved); System.out.println (" Step 7"); //document.setContentType("zip"); System.out.println (" Step 8"); ByteArrayInputStream baistream =new ByteArrayInputStream(fileReta); System.out.println (" Step 9"); ZipInputStream zistream =new ZipInputStream(baistream); System.out.println (" Step 10"); ZipEntry entry;System.out.println (" Step 11"); while ((entry = zistream.getNextEntry()) != null) { System.out.println("Unzipping: " + entry.getName()); int size; byte[] buffer = new byte[2048]; System.out.println (" Now inside inner while"); ByteArrayOutputStream bos =new ByteArrayOutputStream(buffer.length); while ((size = zistream.read(buffer, 0, buffer.length)) != -1) { System.out.println (" Step 12 :: inside inner while"); bos.write(buffer, 0, size);}System.out.println (" Step 13 "); document.setObjectName(entry.getName()); document.setContentType("crtext"); document.setContent(bos); System.out.println (" Step 14 "); // document.save(); System.out.println (" Step 15 "); document.link(path); System.out.println (" Step 16 "); document.save(); System.out.println (" Step 17 "); //bos.flush(); //bos.close(); }System.out.println (" Step 18::prior to close "); zistream.close();System.out.println (" Step 19::after close "); }
The above given code extracts the zip files into the location of my desire (path).
But the scenario i am facing is this:
1) If the zip file has 3 text files in it, only the middle file gets extracted into the desired location .
2) For the remaining files i get the below seen exception
Step 1
Step 2
Step 3 ::July30TestProject.zip
Step 4
Step 5 ::com.documentum.fc.client.impl.session.StrongSessionHandle@dd422e
Step 6 ::com.documentum.fc.client.DfDocument___PROXY@241a0d
Step 7
Step 8
Step 9
Step 10
Step 11
Unzipping: MyTest2.txt
Now inside inner while
Step 12 :: inside inner while
Step 13
Step 14
Step 15
Step 16
Step 17
Unzipping: MyTest1.txt
Now inside inner while
Step 12 :: inside inner while
Step 13
Step 14
Step 15

There seems to be an error called "[DM_SYSOBJECT_E_ALREADY_LINKED]error".
Could any one please help me with this error to analyse a solution.
Thanks & Regards
