Hi,
I am using documentum 6.0 and I would like to export a docx document from the content server to my local harddrive. The following is my code:
-
private void doExport( IDfId docId, String destDir, String exportName, String exportFormat, IDfSession session ) throws DfException {
try {
System.out.println("ServiceRequestMsgBody.java: start doExport 1 - docId: " + docId.toString());
IDfClientX clientx = new DfClientX();
IDfSysObject sysObj = (IDfSysObject) session.getObject( docId );
System.out.println("ServiceRequestMsgBody.java: start doExport 2");
if( sysObj == null ) {
System.out.println("Object " + docId + " can not be found.");
return;
}
//System.out.println("ServiceRequestMsgBody.java: start doExport 2");
sysObj.setObjectName(exportName);
IDfExportOperation operation = clientx.getExportOperation();
operation.setDestinationDirectory( destDir );
IDfExportNode node = (IDfExportNode)operation.add( sysObj );
node.setFormat( exportFormat );
System.out.println( "exported file path: " + node.getFilePath() );
} catch (DfException e) {
e.printStackTrace();
} catch (Exception e2) {
e2.printStackTrace();
} finally {
System.out.println("export finished.");
}
}
-
this is how I invoke the method
this.doExport(docId, "C:/dll", "new_report", "docx", workitem.getSession());
Whenever I call this export method, an exception will be thrown at the execution line in bold:
operation.execute();
The error thrown is as follows:
java.lang.NullPointerException

Any idea what went wrong here? Is exporting of docx document type supported in documentum 6.0? And if not, are there any recommended workaround?
PS: I am not able to change the file type to a doc file due to some requirements stated by my users. So I have to work with the docx file format. Any help is greatly appreciated. Thanks in advance.
