public class AlfrescoUtil {

public static void main(String args[]) throws Exception {
String fileName = "upload.jpg";
WebServiceFactory.setEndpointAddress("http://localhost:8080/alfresco/soapapi");
AuthenticationUtils.startSession("admin", "admin");
ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
RepositoryServiceSoapBindingStub repositoryService =WebServiceFactory.getRepositoryService();

Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
String parentSpace = "/app:company_home/cm:ACH_Space";
ParentReference parentReference = new ParentReference (storeRef, null, parentSpace, Constants.ASSOC_CONTAINS, null);
parentReference.setChildName("cm:"+ fileName);

NamedValue[] contentProps = new NamedValue[3];
contentProps[0] = Utils.createNamedValue(Constants.PROP_TITLE,fileName);
contentProps[1] = Utils.createNamedValue(Constants.PROP_DESCRIPTION, fileName);
contentProps[2] = Utils.createNamedValue(Constants.PROP_NAME, fileName);

NamedValue[] aspectProps = new NamedValue[3];
aspectProps[0] = Utils.createNamedValue("{mandate}UMRN","18062014_01");
aspectProps[1] = Utils.createNamedValue("{mandate}IRN", "18062014_01");
aspectProps[2] = Utils.createNamedValue("{mandate}status", "TDS");

CMLAddAspect addAspect = new CMLAddAspect();
addAspect.setAspect("{mandate}mandateImage");
addAspect.setProperty(aspectProps);
addAspect.setWhere(new Predicate(new Reference[] { parentReference }, null, null));
addAspect.setWhere_id("1");

CMLCreate create = new CMLCreate("1", parentReference, parentReference.getUuid(), Constants.ASSOC_CONTAINS,null, Constants.PROP_CONTENT, contentProps);

CML cml = new CML();
cml.setCreate(new CMLCreate[] { create });
cml.setAddAspect(new CMLAddAspect[] { addAspect });
UpdateResult[] result1 = repositoryService.update(cml);
Reference content = result1[0].getDestination();
FileInputStream is = new FileInputStream("C:\\Users\\0021083\\Desktop\\PostGoLive4.jpg");

byte[] bytes = ContentUtils.convertToByteArray(is);

ContentFormat format = new ContentFormat("image/jpeg", "UTF-8");
contentService.write(content, Constants.PROP_CONTENT, bytes,format);
System.out.println("File Uploaded Successfully");
}

You can simply use the out-of-the-box webscripts available to upload and get content of the files from the repository and invoke them through your java code.

Webscript to upload a content - tomcat\webapps\alfresco\WEB-INF\classes\alfresco\templates\webscripts\org\alfresco\repository\upload\upload.post.desc.xml
Webscript to get the content - tomcat\webapps\alfresco\WEB-INF\classes\alfresco\templates\webscripts\org\alfresco\cmis\content.get.desc.xml

Hope this helps.

The file is still there its just not "exploded".   There's no change required.
