MS Graph API: Getting 404 when saving to _layouts folder

I'm using the MS Graph Java SDK to save a file to user's OneDrive and under a given path:
#Test
public void createDriveItem() {
String fileName = "moon.pdf";
String fullPath = "a/_layouts/b" + fileName;
byte[] content = Files.readAllBytes(Paths.get(fileName));
graph.users(userId)
.drive()
.root()
.itemWithPath(encodePath(fullPath))
.content()
.buildRequest()
.put(content);
}
private String encodePath(String path) {
String encoding = StandardCharsets.UTF_8.name();
try {
return URLEncoder.encode(path, encoding);
} catch (UnsupportedEncodingException e) {
return path;
}
}
I'm using MS Graph Java SDK v2.5.0, Java 11.
However, this request fails with 404 : Not Found. It also fails if I don't encode the path. It looks like the /_layouts/ which is making troubles because, once I add something to it, the request works.
Also, I reproduced this error with a number of accounts.
My question is: Is this actually expected? If yes, why does creating the same folder structure work when done through the web UI?

I believe you should not be able to add items into /_layouts/ on SharePoint Online.

How do you define a stored procedure in java?

I've worked with web on asp.net C# defining connections with the following structure
try
{
sqlConnection = new SqlConnection(dbConnectionString);
SqlCommand command = new SqlCommand("sp_Test", sqlConnection);
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("#Id", SqlDbType.VarChar).Value = txtId.Text;
command.Parameters.Add("#Name", SqlDbType.DateTime).Value = txtName.Text;
sqlConnection.Open();
return command.ExecuteNonQuery();
sqlConnection.Close();
}
catch (SqlException ex)
{
Console.WriteLine("SQL MESSAGE Error" + ex.Message.ToString());
return 0;
}
...but I'm looking for its equivalent in java. The application I'm working on it is only local. I just need to connect my netbeans, the java IDE I'll use, to my ORACLE Database. The version of the database is Oracle 11g release 2. Thanks for the help!

Eclipse Plug-in use standard Format function in the code

I'm working on a plugin for Eclipse and I created a StructuredTextEditor. The editor contains an XML. And I want to align the code nicely (like indent etc.). I search a possibility to apply the standard function "Format" of Eclipse SHIFT+Ctrl+F.
I found a code snippet that does exaclty this but I didn't get it to work:
String commandId = IJavaEditorActionDefinitionIds.FORMAT;
IHandlerService handlerService = (IHandlerService)PlatformUI.getWorkbench().getService(IHandlerService.class);
try {
handlerService.executeCommand(commandId, null);
} catch (Exception e1) {
e1.printStackTrace();
}
I always get the following Exception:
org.eclipse.core.commands.NotHandledException: There is no handler to execute for command org.eclipse.jdt.ui.edit.text.java.format
Does anyone can help me get running this code, or got en other solution to format the xml content, its important to use the same format like the eclipse formatter uses.

Thanks to greg-449 I searched the correct function to call and found it.
Here is my function that works with StructuredTextEditor.
private void formatString() {
String commandId = "org.eclipse.wst.sse.ui.format.document";
IHandlerService handlerService = (IHandlerService) PlatformUI.getWorkbench().getService(IHandlerService.class);
try {
handlerService.executeCommand(commandId, null);
} catch (Exception e1) {
}
}

How to execute the Windows 'printto' verb using Java?

In the past I have used the 'printto' verb to print PDFs from with a .Net application. It looked something like this:
ProcessStartInfo psi = new ProcessStartInfo(file);
psi.Verb = "printto"; // print to given printer
psi.Arguments = "LPT1";
psi.CreateNoWindow = true;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.ErrorDialog = true;
Process.Start(psi);
How can I do this from a Java application? Or is there an alternative approach? Note that the target platform will always be Windows.

Please try this.
public void print() {
//The desktop api can help calling native applications in windows
Desktop desktop = Desktop.getDesktop();
try {
desktop.print(new File("yourFile.pdf"));
} catch (IOException e) {
e.printStackTrace();
}
}
Please Note : This is the easy fix. You can also use java's Print API to achieve the same thing

Running a Java program with a .dll from Adobe AIR's native process

I would like to be able to operate a scanner from my AIR application. Since there's no support for this natively, I'm trying to use the NativeProcess class to start a jar file that can run the scanner. The Java code is using the JTwain library to operate the scanner. The Java application runs fine by itself, and the AIR application can start and communicate with the Java application. The problem seems to be that any time I attempt to use a function from JTwain (which relies on the JTwain.dll), the application dies IF AIR STARTED IT.
I'm not sure if there's some limit about referencing dll files from the native process or what. I've included my code below
Java code-
while(true)
{
try {
System.out.println("Start");
text = in.readLine();
Source source = SourceManager.instance().getCurrentSource();
System.out.println("Java says: "+ text);
}
catch (IOException e)
{
System.err.println("Exception while reading the input. " + e);
}
catch (Exception e) {
System.out.println("Other exception occured: " + e.toString());
}
finally {
}
}
}
Air application-
import mx.events.FlexEvent;
private var nativeProcess:NativeProcess;
private var npInfo:NativeProcessStartupInfo;
private var processBuffer:ByteArray;
private var bLength:int = 0;
protected function windowedapplication1_applicationCompleteHandler(event:FlexEvent):void
{
var arg:Vector.<String> = new Vector.<String>;
arg.push("-jar");
arg.push(File.applicationDirectory.resolvePath("Hello2.jar").nativePath);
processBuffer = new ByteArray;
npInfo = new NativeProcessStartupInfo;
npInfo.executable = new File("C:/Program Files/Java/jre6/bin/javaw.exe");
npInfo.arguments = arg;
nativeProcess = new NativeProcess;
nativeProcess.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onStandardOutputData);
nativeProcess.start(npInfo);
}
private function onStandardOutputData(e:ProgressEvent):void
{
tArea.text += nativeProcess.standardOutput.readUTFBytes(nativeProcess.standardOutput.bytesAvailable);
}
protected function button1_clickHandler(event:MouseEvent):void
{
tArea.text += 'AIR app: '+tInput.text + '\n';
nativeProcess.standardInput.writeMultiByte(tInput.text + "\n", 'utf-8');
tInput.text = '';
}
protected function windowedapplication1_closeHandler(event:Event):void
{
nativeProcess.closeInput();
}
]]>
</fx:Script>
<s:Button label="Send" x="221" y="11" click="button1_clickHandler(event)"/>
<s:TextInput id="tInput" x="10" y="10" width="203"/>
<s:TextArea id="tArea" x="10" width="282" height="88" top="40"/>
I would love some explanation about why this is dying. I've done enough testing that I know absolutely that the line that kills it is the SourceManager.instance().getCurrentSource(). I would love any suggestions. Thanks.

When calling Java add this -Djava.library.path=location_of_dll to the command line

I have 0 experience with Air, but this reminded me of a Java issue I once spent some time figuring out. I don't have a suggestion on why the scanning doesn't work, but I think a stack trace would be your best friend right now.
I'm guessing you're relying on this line to capture and display it?
nativeProcess.standardOutput.readUTFBytes(nativeProcess.standardOutput.bytesAvailable);
However, you are writing IOExceptions to System.err - is there a nativeProcess.standardError you could read in Air? Alternatively, output everything to System.out.
