I have a web application and i need to export a list to a .xlsx or .pdf format. During exporting the page, page should contain the page header of the company along with the list. How is it possible? I am doing this project in grails. Is there any plugin which would make this possible. I've already tried Export Plugin in Grails, it does not have that facility.
we are currently creating some exports to PDF with Grails. The reports contain also tables and different logos in the header.
We are using the itext library which fits pretty good our requirements. You have to be aware that the newer itext versions are not open source.
Here is a sample code snippet:
Document document = new Document(PageSize.A4)
def baos= new ByteArrayOutputStream(30)
def dos= new DataOutputStream(baos)
PdfWriter writer = PdfWriter.getInstance(document, dos)
PageNumberEventHelper events = new PageNumberEventHelper()
writer.setBoxSize("art", new Rectangle(36, 54, 559, 788))
writer.setPageEvent(events);
Font titleFont = new Font(Font.UNDEFINED, 22, Font.BOLD)
document.open()
// render title
document.addTitle(getMessage('pricelist.title', [(new Date()).format('dd.MM.yyyy')]));
document.add(new Paragraph(getMessage('pricelist.title', [(new Date()).format('dd.MM.yyyy')]), titleFont))
document.add(new Paragraph(' '))
...
document.close()
try jasper plugin, you can make you own style output

I have a requirement to show multiple languages in a single PDF. We are using jsPDF library.
i tried with different methods
Method 1 :
var doc = new jsPDF()
doc.text(10, 10, 'This is a test')
doc.setLanguage("en-US")
doc.save('english.pdf')
Method 2
doc.addFont("test/reference/MouhitsuBold.ttf", "Mouhitsu", "bold");
doc.setFont("Mouhitsu", "bold");
Both methods are not working for me.
Anyone who developed this scenario in your project please do the help.
I have a jasper report where the text fields are having hyper links to share point documents.The links work just fine in report and in other export formats such as excel and pdf but when exported to pptx , only the text fields are exported but not the links.
FYI -- the jasper reports version is 5.6.1
Plz help if anyone has a solution to my problem.
I have tested it (with hyperlinkType="Reference") and can not find any problems.
This is how I export to pptx
JRPptxExporter exporter = new JRPptxExporter();
File outputFile = new File("test.pptx");
exporter.setExporterInput(new SimpleExporterInput(print));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(outputFile));
SimplePptxReportConfiguration configuration = new SimplePptxReportConfiguration();
configuration.setIgnoreHyperlink(false);
exporter.setConfiguration(configuration);
exporter.exportReport();
Naturally the hyper link does not work if your are in design mode (since its design mode) you need to switch to presentation mode.
If you still have problems please post jrxml related to your textField definition and your code for exporting to pptx.
Trying to fix an old .asp site to work on an ipad. One of the features is the users ability to download their search results into an excel worksheet. The code uses:
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "attachment;filename=results.xls"
Response.CharSet = "iso-8859-1"
When viewing the site on the ipad, when the link is click for the page with the code above it does nothing, just spins. Is it the fact that I am trying to export the data as excel, I have read in some posts how it is the encoding! Should I convert the code to export the results page as a csv file and then allow the user to open it in anything they want/have available? What's the best way to do it to hit the most devices...
Thanks
In the past i'd a same scenario so what i did:
FILE: DOWNLOAD.ASP
<%
' get the file to download
myFile = request.querystring("File")
myFullPath = "c:\name_folder\" & myFile ' example of full path and filename
' set headers
Response.ContentType = "application/octet-stream"
Response.AddHeader "Content-Disposition", "attachment; filename=" & myFile
' send the file using the stream as
Set adoStream = CreateObject("ADODB.Stream")
adoStream.Open()
adoStream.Type = 1
adoStream.LoadFromFile(myFullPath)
Response.BinaryWrite adoStream.Read()
adoStream.Close
Set adoStream = Nothing
%>
FILE: HTML
Download Excel file
This example is full working with Ipad using the native browser Safari.
The file Result.xls is downloaded and loaded in the Viewer whitout the capability to be edit.
My iPad users use the App QuickOffice to let the file be saved in a virtual folder, rename the file, delete, ... but they cant edit the file, that App is just for manage the files and isnt required for download the file.
If your user need also edit the XLS file on the iPad i suggest to use (for example) the Google App Document, it let the user to edit and manage the file directly in the browser.
Hope it help
I'm new to search engines and web crawlers. Now I want to store all the original pages in a particular web site as html files, but with Apache Nutch I can only get the binary database files. How do I get the original html files with Nutch?
Does Nutch support it? If not, what other tools can I use to achieve my goal.(The tools that support distributed crawling are better.)
Well, nutch will write the crawled data in binary form so if if you want that to be saved in html format, you will have to modify the code. (this will be painful if you are new to nutch).
If you want quick and easy solution for getting html pages:
If the list of pages/urls that you intend to have is quite low, then better get it done with a script which invokes wget for each url.
OR use HTTrack tool.
EDIT:
Writing a your own nutch plugin will be great. Your problem will get solved plus you can contribute to nutch by submitting your work !!! If you are new to nutch (in terms of code & design), then you will have to invest lot of time building a new plugin ... else its easy to do.
Few pointers for helping your initiative:
Here is a page which talks about writing own nutch plugin.
Start with Fetcher.java. See lines 647-648. That is the place where you can get the fetched content on per url basis (for those pages which got fetched successfully).
pstatus = output(fit.url, fit.datum, content, status, CrawlDatum.STATUS_FETCH_SUCCESS);
updateStatus(content.getContent().length);
You should add code right after this to invoke your plugin. Pass content object to it. By now, you would have guessed that content.getContent() is the content for url you want. Inside the plugin code, write it to some file. Filename should be based on the url name else it will be difficult to work with that. Url can be obtained by fit.url.
You must do modifications in run Nutch in Eclipse.
When you are able to run, open Fetcher.java and add the lines between "content saver" command lines.
case ProtocolStatus.SUCCESS: // got a page
pstatus = output(fit.url, fit.datum, content, status, CrawlDatum.STATUS_FETCH_SUCCESS, fit.outlinkDepth);
updateStatus(content.getContent().length);'
//------------------------------------------- content saver ---------------------------------------------\\
String filename = "savedsites//" + content.getUrl().replace('/', '-');
File file = new File(filename);
file.getParentFile().mkdirs();
boolean exist = file.createNewFile();
if (!exist) {
System.out.println("File exists.");
} else {
FileWriter fstream = new FileWriter(file);
BufferedWriter out = new BufferedWriter(fstream);
out.write(content.toString().substring(content.toString().indexOf("<!DOCTYPE html")));
out.close();
System.out.println("File created successfully.");
}
//------------------------------------------- content saver ---------------------------------------------\\
To update this answer -
It is possible to post process the data from your crawldb segment folder, and read in the html (including other data nutch has stored) directly.
Configuration conf = NutchConfiguration.create();
FileSystem fs = FileSystem.get(conf);
Path file = new Path(segment, Content.DIR_NAME + "/part-00000/data");
SequenceFile.Reader reader = new SequenceFile.Reader(fs, file, conf);
try
{
Text key = new Text();
Content content = new Content();
while (reader.next(key, content))
{
System.out.println(new String(content.GetContent()));
}
}
catch (Exception e)
{
}
The answers here are obsolete. Now, it is simply possible to get the plain HTML-files with nutch dump. Please see this answer.
In apache Nutch 2.3.1
You can save the raw HTML by edit the Nutch code firstly run the nutch in eclipse by following https://wiki.apache.org/nutch/RunNutchInEclipse
After you finish ruunning nutch in eclipse edit file FetcherReducer.java , add this code to the output method, run ant eclipse again to rebuild the class
Finally the raw html will added to reportUrl column in your database
if (content != null) {
ByteBuffer raw = fit.page.getContent();
if (raw != null) {
ByteArrayInputStream arrayInputStream = new ByteArrayInputStream(raw.array(), raw.arrayOffset() + raw.position(), raw.remaining());
Scanner scanner = new Scanner(arrayInputStream);
scanner.useDelimiter("\\Z");//To read all scanner content in one String
String data = "";
if (scanner.hasNext()) {
data = scanner.next();
}
fit.page.setReprUrl(StringUtil.cleanField(data));
scanner.close();
}
This one very simple thing I can't find the right technique. What I want is to open a .dotx template, make some changes and save as the same name but .docx extension. I can save a WordprocessingDocument but only to the place it's loaded from. I've tried manually constructing a new document using the WordprocessingDocument with changes made but nothing's worked so far, I tried MainDocumentPart.Document.WriteTo(XmlWriter.Create(targetPath)); and just got an empty file.
What's the right way here? Is a .dotx file special at all or just another document as far as the SDK is concerned - should i simply copy the template to the destination and then open that and make changes, and save? I did have some concerns if my app is called from two clients at once, if it can open the same .dotx file twice... in this case creating a copy would be sensible anyway... but for my own curiosity I still want to know how to do "Save As".
I would suggest just using File.IO to copy the dotx file to a docx file and make your changes there, if that works for your situation. There's also a ChangeDocumentType function you'll have to call to prevent an error in the new docx file.
File.Copy(#"\path\to\template.dotx", #"\path\to\template.docx");
using(WordprocessingDocument newdoc = WordprocessingDocument.Open(#"\path\to\template.docx", true))
{
newdoc.ChangeDocumentType(WordprocessingDocumentType.Document);
//manipulate document....
}
While M_R_H's answer is correct, there is a faster, less IO-intensive method:
Read the template or document into a MemoryStream.
Within a using statement:
open the template or document on the MemoryStream.
If you opened a template (.dotx) and you want to store it as a document (.docx), you must change the document type to WordprocessingDocumentType.Document. Otherwise, Word will complain when you try to open the document.
Manipulate your document.
Write the contents of the MemoryStream to a file.
For the first step, we can use the following method, which reads a file into a MemoryStream:
public static MemoryStream ReadAllBytesToMemoryStream(string path)
{
byte[] buffer = File.ReadAllBytes(path);
var destStream = new MemoryStream(buffer.Length);
destStream.Write(buffer, 0, buffer.Length);
destStream.Seek(0, SeekOrigin.Begin);
return destStream;
}
Then, we can use that in the following way (replicating as much of M_R_H's code as possible):
// Step #1 (note the using declaration)
using MemoryStream stream = ReadAllBytesToMemoryStream(#"\path\to\template.dotx");
// Step #2
using (WordprocessingDocument newdoc = WordprocessingDocument.Open(stream, true)
{
// You must do the following to turn a template into a document.
newdoc.ChangeDocumentType(WordprocessingDocumentType.Document);
// Manipulate document (completely in memory now) ...
}
// Step #3
File.WriteAllBytes(#"\path\to\template.docx", stream.GetBuffer());
See this post for a comparison of methods for cloning (or duplicating) Word documents or templates.
