I am trying to display a pdf saved in FileSystemStorage inside the browsercomponent, but it keeping giving me this error on the console: [0813/072549.347989:INFO:CONSOLE(37)] "Not allowed to load local resource: file://home//Chapter_11.pdf#toolbar=0&navpanes=0&scrollbar=0&statusbar=0&messages=0&scrollbar=0&view=FitH", source: https://cn1app/streams/1 (37) [0813/072551.123557:INFO:CONSOLE(0)] "Not allowed to load local resource: file://home//Chapter_11.pdf#toolbar=0&navpanes=0&scrollbar=0&statusbar=0&messages=0&scrollbar=0&view=FitH", source: https://cn1app/streams/1 (0) . Its like there is a restriction that I need to work around. How can I go around this?
Edits... Added information below.
This is the code I am using:
Form hi;
Container loadingMsg;
public void Home(){
Form form = new Form("Display pdf", new BorderLayout());
Button showPdf = new Button("Show Pdf");
showPdf.addActionListener(l->{
show();
});
form.add(BorderLayout.CENTER, showPdf);
form.show();
}
private void show(){
hi = new Form("PDF Viewer", new BorderLayout());
Label loadingLabel = new Label("Loading PDF...");
loadingMsg = FlowLayout.encloseCenter(loadingLabel);
hi.add(BorderLayout.NORTH, loadingMsg);
String pdfUrl = "https://as.vanderbilt.edu/chemistry/Rizzo/chem220a/Chapter_11.pdf";
String fileName = FileSystemStorage.getInstance().getAppHomePath() + "Chapter_11";
if (!FileSystemStorage.getInstance().exists(fileName)) {
Util.downloadUrlToFileSystemInBackground(pdfUrl, fileName);
};
hi.addShowListener(l -> {
run1(fileName);
});
hi.show();
}
private void run1(String fileName) {
BrowserComponent browser = new BrowserComponent();
browser.setPage(getPdfViewerHtml(fileName), null);
hi.add(BorderLayout.CENTER, browser);
loadingMsg.remove();
hi.revalidate();
}
private String getPdfViewerHtml(String fileName) {
String html = "<!DOCTYPE html>\n"
+ "<html>\n"
+ " <head>\n"
+ " <title>PDF Viewer</title>\n"
+ " <style>\n"
+ " html{\n"
+ " height: 100%;\n"
+ " padding: 0;\n"
+ " }\n"
+ " body{\n"
+ " height: 100%;\n"
+ " overflow-y: hidden;\n"
+ " position: fixed;\n"
+ " width: 100%;\n"
+ " padding: 0;\n"
+ " margin: 0;\n"
+ " }\n"
+ " </style>\n"
+ " </head>\n"
+ " <body>\n"
+ "\n"
+ " <div style= \"height: 100%; margin: 0;\">\n"
+ " <iframe\n"
+ " src='"+fileName+"#toolbar=0&navpanes=0&scrollbar=0&statusbar=0&messages=0&scrollbar=0&view=FitH'\n"
+ " width=\"100%\"\n"
+ " height=\"100%\"\n"
+ " >\n"
+ " <p>This browser does not support PDF!</p>\n"
+ " </iframe>\n"
+ "\n"

return html;
}
So in the method String getPdfViewerHtml(String fileName),when i replace the fileName with a URL, thing works fine. But I want it to display a file from FileSystemStorage.
The code below should support the local embed tag correctly:
private Container loadingMsg;
public void start() {
if (current != null) {
current.show();
return;
}
home();
}
public void home() {
Form form = new Form("Display pdf", new BorderLayout());
Button showPdf = new Button("Show Pdf");
showPdf.addActionListener(l -> {
showPdf.setText("Dowloading PDF...");
showPdf.setEnabled(false);
form.revalidate();
show();
});
form.add(BorderLayout.CENTER, showPdf);
form.show();
}
private void show() {
String root = getAppHomePath() + "httpdocs/";
mkdir(root);
hi = new Form("PDF Viewer", new BorderLayout());
Label loadingLabel = new Label("Loading PDF...");
loadingMsg = FlowLayout.encloseCenter(loadingLabel);
hi.add(BorderLayout.NORTH, loadingMsg);
String pdfUrl = "https://as.vanderbilt.edu/chemistry/Rizzo/chem220a/Chapter_11.pdf";
String fileName = root + "/Chapter_11.pdf";
if (!FileSystemStorage.getInstance().exists(fileName)) {
Util.downloadUrlToFile(pdfUrl, fileName, false);
try {
run1(docRoot, "Chapter_11.pdf");
} catch (IOException ex) {
Log.e(ex);
}
} else {
try {
run1(docRoot, fileName);
} catch (IOException ex) {
Log.e(ex);
}
}
hi.show();
}
private void run1(String docRoot, String fileName) throws IOException {
BrowserComponent browser = new BrowserComponent();
String localUrl = fileName;
String htmlPage = getPdfViewerHtml(localUrl);
File indexHtml = new File(docRoot, "index.html");
writeStringToFile(indexHtml, htmlPage);
browser.setURL(docRoot + "/index.html");
hi.add(BorderLayout.CENTER, browser);
loadingMsg.remove();
hi.revalidate();
}
private String getPdfViewerHtml(String fileName) {
String html = "<!DOCTYPE html>\n"

}

XpsDocument is loaded from disk
Create a FixedDocumentSequence via XpsDocument.GetFixedDocumentSequence Method ()
Display the via a DocumentViewer
Would like to add to add header and footer to print
I don't need to add the header and footer back to the XPS document - only to the print output
I tried implementing DocumentPaginator but cannot get the sizing or placement to work
NOT the same as this footer to FlowDocument
I use the solution there for FlowDocuments just fine
Convert XAML Flow Document to XPS with Style
On the FixedDocumentSequence the sizing comes from document (I guess)
For example could mix landscape and portrait
I cannot figure out how to hook into the sizing and make room for a header and footer
I can stamp a header on it but it is over the top of the page
And landscape pages are cut off
Cannot assign a PageSize when it comes from a FixedDocumentSequence
As stated in the link it is a suggested pages size
DocumentPage.Size is read only
Even if I create DocumentPage of the Size I want when the page is loaded using DocumentPaginator.GetPage then the Size is overwritten
Even worse the DocumentPaginator does not seem to be properly aware of the Size as it does not deal with mixed landscape and portrait properly. Landscape is printed portrait and just runs off the page.
some one asked me to post code
there also might be a just plain better approach
see footer to FlowDocument for how to use it
this is where it breaks

Not sure from your code what you are trying to do, but if its synchronous you can trace it after SendMessageToWinMachine() ,else you can use CallBack Method for asynchronus call.

The column exists, so I don't know what is the problem...
The code line is this one:
Float distancia_restante = (float) ( Integer.parseInt(rs.getString("DistanciaMision")) - (myodometer - initialodometer));
The same problem appears on other columns but it usually crash here.
Thank you!
Edit: ok, this is the whole method:

And the statement, maybe i'm doing something wrong?:
private static Statement conStatement(Properties properties){
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"; // Load the JDBC driver
String dbURL = "jdbc:sqlserver://"
+ properties.getProperty("qualcomm.action.JDBC.MSSQLServerAccess.ddbbserverIP")
+ ";DatabaseName="
+ properties.getProperty("qualcomm.action.JDBC.MSSQLServerAccess.ddbbName")
+ ";SelectMethod=Cursor;"; // Connect to a server and database
String userName = properties.getProperty("qualcomm.action.JDBC.MSSQLServerAccess.userName");
String userPwd = properties.getProperty("qualcomm.action.JDBC.MSSQLServerAccess.userPwd");
Connection dbConn;
try {
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
//log.info("Connection Successful!");
Statement myst = dbConn.createStatement();
return myst;
} catch (Exception e) {
log.error(e);
System.out.println(e);
return null;
}
}
Thanks guys :) Could be something wrong with the statement?
remember that Java is case-sensitive and so can be your table on SQL depending on the way you created them, actually depending on the collation on your DB. If your database is created with a Case Sensitive collation then all object names will be Case Sensitive.
try to check the exact columns name of the column on SQL and access it using [] and the exact case
