Read windows registry info from remote system using Jacob

Im trying to run some WMI queries using JACOB, and so far i've been successfull in getting the services and processes however i need to query the registry to see if a certain key is there
i've stummbled across this link
but i dont understand how to implement it
in order to query the services i've used the following code
ActiveXComponent wmi = null;
wmi = new ActiveXComponent("WbemScripting.SWbemLocator"); <-- side question what is the WbemScripting...
variantParameters[0] = new Variant("localhost");
variantParameters[1] = new Variant("root\\cimv2"); <-- what is this root?
String query = "Select ExitCode,Name,ProcessId,StartMode,State,Status from Win32_Service where State='Running' and Name='MSDTC'";
Variant vCollection = wmiconnect
.invoke("ExecQuery", new Variant(query));
is there a place with decent documentation for this?
and how to implement queries on the registry?
Thanks
UPDATE
Im trying a new implementation where i try to call the StdRegProv
and i have the following code
int HKEY_LOCAL_MACHINE = 0x80000002;
String strKeyPath = "SYSTEM\\CurrentControlSet\\Services";
String [] sNames = new String [5];
ActiveXComponent wmi = new ActiveXComponent("WbemScripting.SWbemLocator");
// no connection parameters means to connect to the local machine
Variant variantParameters[] = new Variant[4];
variantParameters[0] = new Variant("192.168.1.2");
variantParameters[1] = new Variant("root\\default");
variantParameters[2] = new Variant("admin");
variantParameters[3] = new Variant("pass");
Dispatch services = wmi.invoke("ConnectServer", variantParameters).toDispatch();
Dispatch oReg = Dispatch.call(services, "Get", "StdRegProv").toDispatch();
Variant ret = Dispatch.call(oReg, "EnumKey", HKEY_LOCAL_MACHINE, strKeyPath, sNames);
System.out.println("EnumKey: HKEY_LOCAL_MACHINE\\"+strKeyPath+"="+ret);
I was hoping to get the sNames array filled with data but its just nulls

I was unable to do it with Jacob but succeeded using j-interop library
here is the code that cost me so much suffering
IJIAuthInfo authInfo = new JIDefaultAuthInfoImpl("remoteComputerIpAddress", "wmiUserName", "wmiUserPassword");
IJIWinReg registry = null;
try {
registry = JIWinRegFactory.getSingleTon().getWinreg(authInfo, "remoteComputerIpAddress", true);
JIPolicyHandle policyHandle = registry.winreg_OpenHKLM();
JIPolicyHandle policyHandle2 = registry.winreg_OpenKey(policyHandle, "SOFTWARE\\wisemon",
IJIWinReg.KEY_ALL_ACCESS);
// JIPolicyHandle policyHandle3 =
// registry.winreg_OpenKey(policyHandle2,"wisemon",IJIWinReg.KEY_ALL_ACCESS);
System.out.println("Printing first 1000 entries under HKEY_LOCAL_MACHINE\\BCD00000000...");
for (int i = 0; i < 1; i++) {
// String[] values = registry.winreg_EnumKey(policyHandle3,i);
// Object[] values = registry.winreg_EnumValue(policyHandle3,i);
Object[] values = registry.winreg_QueryValue(policyHandle2, "name", 100);
Object[] values2 = registry.winreg_QueryValue(policyHandle2, "date", 100);
System.out.println(new String((byte[]) values[1]));
System.out.println(new String((byte[]) values2[1]));
}
} catch (UnknownHostException | JIException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
System.out.println("Closing registry connection");
registry.closeConnection();
}

Android Rename File using Google Drive REST API v3?

How do I rename a file using the Google Drive REST API on Android? I have searched the internet however I could, but I can't find how to do this.
I am trying to write a sync method that moves and renames the cloud files if it detects that the local copy has been moved or renamed:
void syncMetadataOnly (com.google.api.services.drive.model.File cloud,
java.io.File local) throws IOException {
Workspace.FINF fileInfo = Workspace.getFileInfo (this, local); // Just my metadata object.
Map<String, String> appProperties = cloud.getAppProperties ();
// We keep track of the last rename and move in our private app properties:
long cloudLastRename = appProperties.containsKey ("last-rename") ?
Long.valueOf (appProperties.get ("last-rename")) : 0;
long cloudLastMove = appProperties.containsKey ("last-move") ?
Long.valueOf (appProperties.get ("last-move")) : 0;
boolean needUpdate = false;
boolean needName = false;
boolean needMove = false;
if (fileInfo.lastRename > cloudLastRename) {
// The file was renamed locally since the last sync.
needName = true;
needUpdate = true;
} else fileInfo.title = cloud.getName ();
String oldRecognizedParent = null;
if (fileInfo.lastMove > cloudLastMove) {
// The file was moved to a different folder locally since the last sync.
oldRecognizedParent = getFirstKnownParentId (cloud); // May be null, if not found.
needMove = true;
needUpdate = true;
}
if (needUpdate) {
cloud.setAppProperties (appProperties);
Drive.Files.Update update = mDriveService.files ().update (fileInfo.driveResourceId, null);
if (needName) update.set /// How do I rename the file?
if (needMove) {
if (oldRecognizedParent != null)
update.setRemoveParents (oldRecognizedParent);
update.setAddParents (fileInfo.driveParentId); // Set to the NEW parent's ID.
}
com.google.api.services.drive.model.File result = update.execute ();
}
}
The closest answer I have found is this, but do I really have to use raw HTTP for this?

Gate- Loading a gapp file is taking time .Hoe can I reduce it?

I am working on GATE related project. So, Here I am creating a pipeline through GATE. I am using that .gapp file in my java code. So, for loading a .gapp file, it takes around 10 seconds, which is too much for my application.
How can I solve this issue?
Second problem is that, I have to do System.exit after processing a document to release the memory, if I didn't then I got OutofMemoryError.
So, how can I solve these issues?
My code is like:
public class GateMainClass {
CorpusController application = null;
Corpus corpus = null;
public void processApp(String gateHome, String gapFilePath, String docSourcePath, String isSingleDocument) throws ResourceInstantiationException {
try {
if (!Gate.isInitialised()) {
Gate.runInSandbox(true);
Gate.setGateHome(new File(gateHome));
Gate.setPluginsHome(new File(gateHome, "plugins"));
Gate.init();
}
application = (CorpusController) PersistenceManager.loadObjectFromFile(new File(gapFilePath));
corpus = Factory.newCorpus("main");
application.setCorpus(corpus);
if(isSingleDocument.equals(Boolean.TRUE.toString())) {
Document doc = Factory.newDocument(new File(docSourcePath).toURI().toURL());
corpus.add(doc);
} else {
File[] files;
File folder = new File(docSourcePath);
files = folder.listFiles(new FileUtil.CustomFileNameFilter(".xml"));
Arrays.sort(files, LastModifiedFileComparator.LASTMODIFIED_REVERSE);
for (int i = 0; i < files.length; i++) {
Document doc = Factory.newDocument(files[i].toURI().toURL());
corpus.add(doc);
}
}
application.execute();
} catch (Exception e) {
e.printStackTrace();
} finally {
corpus.clear();
}
}
And my gapp file is like:
1.Document Reset PR
2.Annie English Tokenizer.
3.ANnie Gazetteer.
4.Annie Sentence Spiliter.
5.Annie POS Tagger.
6.GATE morphological Analyser.
7.Flexible gazetteer.
8.HTML markup transfer
9.Main Jape file.

Search Box for Jpanel

I am in the middle of creating an app that allows users to apply for job positions and upload their CVs. I`m currently stuck on trying to make a search box for the admin to be able to search for Keywords. The app will than look through all the CVs and if it finds such keywords it will show up a list of Cvs that contain the keyword. I am fairly new to Gui design and app creation so not sure how to go about doing it. I wish to have it done via java and am using the Eclipse Window builder to help me design it. Any help will be greatly appreciated, hints, advice anything. Thank You.

Well, this not right design approach as real time search of words in all files of given folder will be slow and not sustainable in long run. Ideally you should have indexed all CV's for keywords. The search should run on index and then get the associated CV for that index ( think of indexes similar to tags). There are many options for indexing - simples DB indexing or using Apache Lucene or follow these steps to create a index using Maps and refer this index for search.
Create a map Map<String, List<File>> for keeping the association of
keywords to files
iterate through all files, and for each word in
each file, add that file to the list corresponding to that word in
your index map
here is the java code which will work for you but I would still suggest to change your design approach and use indexes.
File dir = new File("Folder for CV's");
if(dir.exists())
{
Pattern p = Pattern.compile("Java");
ArrayList<String> list = new ArrayList<String>(); // list of CV's
for(File f : dir.listFiles())
{
if(!f.isFile()) continue;
try
{
FileInputStream fis = new FileInputStream(f);
byte[] data = new byte[fis.available()];
fis.read(data);
String text = new String(data);
Matcher m = p.matcher(text);
if(m.find())
{
list.add(f.getName()); // add file to found-keyword list.
}
fis.close();
}
catch(Exception e)
{
System.out.print("\n\t Error processing file : "+f.getName());
}
}
System.out.print("\n\t List : "+list); // list of files containing keyword.
} // IF directory exists then only process.
else
{
System.out.print("\n Directory doesn't exist.");
}
Here you get the files list to show now for "Java". As I said use indexes :)

Thanks for taking your time to look into my problem.
I have actually come up with a solution of my own. It is probably very amateur like but it works for me.
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent arg0)
{
list.clear();
String s = SearchBox.getText();
int i = 0,present = 0;
int id;
try
{
Class.forName(driver).newInstance();
Connection conn = DriverManager.getConnection(url+dbName,userName,password);
Statement st = conn.createStatement();
ResultSet res = st.executeQuery("SELECT * FROM javaapp.test");
while(res.next())
{
i = 0;
present = 0;
while(i < 9)
{
String out = res.getString(search[i]);
if(out.toLowerCase().contains(s.toLowerCase()))
{
present = 1;
break;
}
i++;
}
if(tglbtnNormalshortlist.isSelected())
{
if(present == 1 && res.getInt("Shortlist") == 1)
{
id = res.getInt("Candidate");
String print = res.getString("Name");
list.addElement(print+" "+id);
}
}
else
{
if(present == 1 && res.getInt("Shortlist") == 0)
{
id = res.getInt("Candidate");
String print = res.getString("Name");
list.addElement(print+" "+id);
}
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
});

Open Office 1.1.4 Export to PDF with background images using java

I have a problem that needs solving where we use OpenOffice 1.1.4 templated reports and programmatically export them to PDF.
The team who create the templates have recently changed the header image and some images in a table to background images (before they were just inserted) since this change the current program is not creating the PDFs with the images. We can export from OpenOffice manually and the images are included. Can anyone help with a change I may need to make to get these background images included please?
The current code:
private void print(XInterface xComponent,
PrintRequestDTO printReq, File sourceFile,
Vector<String> pages) throws java.lang.Exception {
String pageRange;
// XXX create the PDF via OOo export facility
com.sun.star.frame.XStorable pdfCreator = (com.sun.star.frame.XStorable) UnoRuntime
.queryInterface(
com.sun.star.frame.XStorable.class,
xComponent);
PropertyValue[] outputOpts = new PropertyValue[2];
outputOpts[0] = new PropertyValue();
outputOpts[0].Name = "CompressionMode";
outputOpts[0].Value = "1"; // XXX Change this perhaps?
outputOpts[1] = new PropertyValue();
outputOpts[1].Name = "PageRange";
if (printReq.getPageRange() == null) {
pageRange = "1-";
}
else {
if (printReq.getPageRange().length() > 0) {
pageRange = printReq.getPageRange();
}
else {
pageRange = "1-";
}
}
log.debug("Print Instruction - page range = "
+ pageRange);
PropertyValue[] filterOpts = new PropertyValue[3];
filterOpts[0] = new PropertyValue();
filterOpts[0].Name = "FilterName";
filterOpts[0].Value = "writer_pdf_Export"; // MS Word 97
filterOpts[1] = new PropertyValue();
filterOpts[1].Name = "Overwrite";
filterOpts[1].Value = new Boolean(true);
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
if (pages.size() == 0) { // ie no forced page breaks
// set page range
outputOpts[1].Value = pageRange;
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
File outputFile = new File(
sourceFile.getParent(),
printReq.getOutputFileName()
+ ".pdf");
StringBuffer sPDFUrl = new StringBuffer(
"file:///");
sPDFUrl.append(outputFile.getCanonicalPath()
.replace('\\', '/'));
log.debug("PDF file = " + sPDFUrl.toString());
if (pdfCreator != null) {
sleep();
pdfCreator.storeToURL(sPDFUrl.toString(),
filterOpts);
}
}
else if (pages.size() > 1) {
throw new PrintDocumentException(
"Only one forced split catered for currently");
}
else { // a forced split exists.
log.debug("Page break found in "
+ (String) pages.firstElement());
String[] newPageRanges = calculatePageRanges(
(String) pages.firstElement(), pageRange);
int rangeCount = newPageRanges.length;
for (int i = 0; i < rangeCount; i++) {
outputOpts[1].Value = newPageRanges[i];
log.debug("page range = " + newPageRanges[i]);
filterOpts[2] = new PropertyValue();
filterOpts[2].Name = "FilterData";
filterOpts[2].Value = outputOpts;
String fileExtension = (i == 0 && rangeCount > 1) ? "__Summary.pdf"
: ".pdf";
File outputFile = new File(
sourceFile.getParent(),
printReq.getOutputFileName()
+ fileExtension);
StringBuffer sPDFUrl = new StringBuffer(
"file:///");
sPDFUrl.append(outputFile.getCanonicalPath()
.replace('\\', '/'));
log.debug("PDF file = " + sPDFUrl.toString());
if (pdfCreator != null) {
log.debug("about to create the PDF file");
sleep();
pdfCreator.storeToURL(
sPDFUrl.toString(), filterOpts);
log.debug("done");
}
}
}
}
Thanks in advance.

Glad that suggestion of making the document visible helped. Since it has ALSO fixed the problem you have a timing/threading issue. I suspect you'll find that another dodgy option of doing a sleep before executing the save to PDF will also allow the images to appear. Neither of these solutions is good.
Most likley best fix is to upgrade to a newer version of Open Office (the API calls you have should still work). Another option would be to try to call the API to ask the document to refresh itself.

After finding the correct property I was able to open the file with the hidden property set to false, this meant when the file was exported to PDF it included the background images. Its a shame I could not find another solultion that kept the file hidden but at least its working.
