Append to HTML file
Hi,
I have a VI that controls a stepper motor attached to a camera. I want people to be able to access this camera and control its position through the web. Is there any way to append an HTML file or icon from labview and rotate the camera with the data sent from the web?
Thank you for your help.
Guillermo Naranjo
Solved!
Go to Solution.
I tried using the labview web publishing tool like you suggested, but when I tried to preview the page (even with the VI running) I only get the border of the front panel without the VI in it. Do you know why this is happening?
Thank you for your help.

Hello Friends,
i want to append a existing html file using jsp.
At the end of the existing html file, i should have a textarea.
if i enter sometext into that textarea, the text should be appended into the same html file.
do u have any idea?.

tskarthikeyanThere is nothing special in file operation in JSP/Servlet except file path. The way you read/write file from java application follow the same. Sample to read a file:
FileReader reader=new FileReader("FileNameWithPath");
BufferedReader buffer=new BufferedReader(reader);
String text=null;
while((text=buffer.readLine())!=null){
FileWriter writer=new FileWriter("FileNameWithPath");
BufferedWriter buffer=new BufferedWriter(writer);
buffer.write("......");To get physical path of HTML file use following method of ServletContext:
getRealPath(String path);The HTML content will be displayed in a JSP. When user clicks on submit button additional content goes to server side. At server side Servlet/JSP updates the html file content and finally displays the same (or other) JSP page with modified HTML content.
Hope this helps.
Thanks,

A working method to load local PDF and HTML files on iOS
I had a lot of trouble getting this to work, and I'm hoping this post saves someone time. Some of the information that's been posted in other locations is either wrong, incomplete, or might only work on Android. By the time you read this message the information here may no longer be accurate, so here's the testing environment:
Window 7
Flash CS 5.5.0
AIR 2.7.0.19530, which was compiled on June 28, 2011
iPad 1, version 4.3.5 of iOS
Let's get started.
On iOS, you load external PDF and HTML files using the StageWebView class.
On Windows, StageWebView works but the HTMLLoader class is a better choice if you're creating a desktop app.
You can also load HTML files by reading in the file's text. The information in this post is only for loading external HTML files.
StageWebView will not load a file that's in File.applicationDirectory. All files bundled in your app are placed in File.applicationDirectory, which means you'll have to copy any external file you wish to load with StageWebView to another directory.
So where can you copy your file? File.applicationStorageDirectory won't work. File.documentsDirectory does work.
Several people have recommended copying to a temporary file using File.createTempFile(). This works, but there's a catch: it seems that, like Windows, StageWebView relies on a file's extension when determining how to load it. When you create a temporary file on iOS using File.createTempFile(), the file will have no extension (and on Windows, File.createTempFile() creates a file with the extension .tmp, which is equally problematic).
The solution to the file extension problem is to rename the temporary file by appending the original file's extension. AIR currently does not have a <file>.rename() function, so you'll have to do it using <tempFile>.moveTo().
Here's some code I've successfully tested several times on both iOS and Windows. The file is copied to the temp directory. The file's extension is restored by just slapping the original file name to the end of the temp file.
private function loadExternalFile():void
var webView = new StageWebView();
webView.stage = this.stage;
webView.viewPort = new Rectangle( 0, 0, 1024, 555 );
// Works with either html or pdf files.
// These are stored in the root of the application directory.
var fileName:String = "euei.pdf";
//var fileName:String = "euei.htm";
var sourceFile = File.applicationDirectory.resolvePath( fileName );
var workingFile = File.createTempFile();
try
sourceFile.copyTo( workingFile, true );
// You have to rename the temp file
var renamedTempFile:File = workingFile.resolvePath(workingFile.nativePath + fileName);
workingFile.moveTo(renamedTempFile, true);
webView.loadURL( renamedTempFile.url );
catch (err:Error) { }I tried this with Flash CS5.5 and AIR 4.0 SDK. Any pdf loaded simply fills the viewPort with black. Also tested with a png version of the pdf and that displayed just fine.
What's the purpose of copying to a temp work file? I found that webView.loadURL( sourceFile.url ); gave me the exact same results.
Any ideas?

Help needed:Printing HTML file using javax.print

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.

I have created an html file that i want to email. I didn't want to email it as an attachment but as the contents of the email(so the recipient opens the email and sees the html file).
How do I do this?hi there,
I am not familiar with Multiparts.....
I want to send a html file as a newsletter so it has graphics
String urlMailContent = "http://java.sun.com/developer/onlineTraining/JavaMail/";
BodyPart urlPart = new MimeBodyPart();
URL urlToAdd = new URL(urlMailContent);
URLDataSource dsURL = new URLDataSource(urlToAdd);
DataSourceurlPart.setDataHandler(new DataHandler(dsURL));with the above code example, what do i set the content to?
My code is below(I can see how my code doesn't work as the BufferedReader doesn't read graphics), can u help me fix it. My problem is that the graphics ar enot coming through.
StringBuffer body = new StringBuffer();
BufferedReader br = new BufferedReader(new FileReader("C:\\Documents and Settings\\Ushantam\\My Documents\\My Office\\Autopax Passenger Services\\IT News Letter\\ITLetter220704.html"));

Abstract Portal Component: How to inclue a HTML file into the response?
Hi experts,
i am currently working on the problem, that i want to access KM inside my AbstractPortalComponent in order to retrieve a HTML File.Afterwars i want to include this file into my IPortalComponentResponse.
IPortalComponentResponse offers the method include(IPortalComponentResponse , IResource)
Is it possible to use this method to achieve my goal?
I have tried this approach:
IResourceContext resourceContext = new ResourceContext(requester);
RID rid = RID.getRID("/documents/test.gif");
IResource resource = ResourceFactory.getInstance().getResource(rid,resourceContext);
response.include(request,resource);
But the problem is that this IResource doesn't match the IResource that is needed for this method.
My IResource belongs to com.sapportals.wcm.repository.IResource
But the Methos just works with com.sapportals.portal.prt.resource.IResource
So can you help me on this one?:)
With Best Regards
MarcusHi,
read the contents of the resource and put them to the output.
Dumb but working piece of code:
private String renderResource(IResource resource, boolean html) {
StringBuffer buf = new StringBuffer("");
try {
IContent content = resource.getUnfilteredContent();
if (content != null) {
InputStream is = content.getInputStream();
byte[] bytes = new byte[(int) content.getContentLength()];
int i = is.read();
int count = 0;
while (i != -1) {
char b = (char) i;
bytes[count] = (byte) i;
count++;
i = is.read();
buf.append(new String(bytes, "UTF-8"));
if (html) {
buf.append("</br>");
} else {
buf.append('\n');
} catch (Exception e) {
// do something
return buf.toString();
hope this helps,

Dynamic html file generation problem
I have a HTML file(abc.html) which is used when user clicks on a particular link in my web application. Web application has been developed in java. Now due to certain law changes , user wants to add some notices to existing HTML file(abc.html). So when he clicks on the old link, he gets abc.html with those notices appended to it. All the notices are different HTML files.
So it looks like simple file append problem. But if it will modify my original file permanently, then it is not helping my purpose.
So my doubt is , how I can append different notices html files to abc.html file and still keep my abc.html file as it is because the changes are based on user conditions. So if X is affected with new laws, he will see abc.html along with notices , if Y is not affected, then he will see abc.html only.The best solution would depend on the implementation details of your current web app, but, likely, the easiest way is to convert your html files to jsps. The jsp can then conditionally include relevant disclaimer fragments.

Writing html file in a jeditorpane
I have read one of your threads titled as "How to insert a string in a JEditorPane (Urgent)". according to this thread I am using insertString() method to write in an jeditorpane. what I am writing is an html file. when I used insertString() method it doesn't show the html content in my jeditotpane. it displays the source code of my html file. I have setContentType("text/html"); moreover I used setText() and it shows the html file correctly but it over writes the previous content of jeditorpane. please help me to be able to
write to a jeditorpane without overwriting and displaying html file properly not its source code.
following is my code:

do{
last = find.lastIndexOf("str");

If you mean a JEditorPane then please use the correct case, so we can be confident you refer to the J2SE class, as opposed to a 3rd party jeditorpane that we neither know, nor support.

We have a software application that programmatically launches the default web browser using the Windows shell execute function ("ShellExecuteA" in the "shell32.dll" library of the Windows API) along with a file path for a saved local html file that is to be displayed. In the case that FireFox is the default browser and the file path for the html file contains any space characters in the html file's file name, Firefox (in this case v7.01) will display an error message "File not Found..." and then will also proceed to open tabs for each of the individual words in the file name, launching as the URL path, each individual word appended to ".com".
In the following example, the path "C:\KSSecOfState\Forms\Kansas Secretary of State - Filings and Forms.htm" when launched programmatically, resulted in the error message "File not Found...Firefox can't find the file at /C:/KSSecOfState/Forms/Kansas." and opened up browser windows for "http://www.secretary.com/", "http://www.of.com/", "http://www.state.com/", "http://www.and.com/", and attempted to launch "http://forms.htm". If the same file (renamed) is launched using the path string "C:\KSSecOfState\Forms\KansasSecretaryOfState-FilingsAndForms.htm" the file opens up correctly in Firefox. Clearly the presence of spaces in the file name is causing the problem.
I should also note that either path (with or without space characters) works properly if pasted directly into the Firefox URL path menu bar for a live instance of Firefox. The test path strings I used were:
C:\KSSecOfState\Forms\KansasSecretaryOfState-FilingsAndForms.htm
C:\KSSecOfState\Forms\Kansas Secretary of State - Filings and Forms.htm
Does anyone know anything about this problem or how to work around it (other than the obvious answer of taking the spaces out of the file name which is not possible for this application). It seems the problem is specific to Firefox. IE works properly if launched programmatically with spaces in the file name passed to it. I haven't tested other browsers yet.
Thanks!If starting from ShellExecute works the same as starting from the command line then there are two options:<br>
Put everything inside double quotes<br>
'''C:\Program Files\Mozilla Firefox\>'''firefox.exe '''"c:\test\svg test.htm"'''<br>
Convert to a valid url with file:// protocol and percentage-escaping the space<br>
'''C:\Program Files\Mozilla Firefox\>'''firefox.exe '''file://c:\test\svg%20test.htm'''<br> -
How to mail the html file using javamail????
hi
i have captured the output of a jsp page in a html file....
now i wish to send it in the mail ( *** not as an attachment)
ie
i wish the output of the jsp ie the html file to be displayed in
the message box (ie text area) ..... and then when recieved by the
receipient it shoud be displayed in the message area....
is there any way to do this ........well as said by my fellow poster googling could have given you quick results.
Anyways,if you are unable to do so checkout the below code snippet.
SendMail.java:
===========
import java.io.File;
import java.io.FileReader;
import java.io.BufferedReader;
import java.util.Properties;
import javax.mail.Session;
import javax.mail.Message;
import javax.mail.Transport;

try{
input = new BufferedReader(new FileReader(fileName));
String str = null;
while ((str = input.readLine()) != null){
sb.append(line);
}catch(Exception exp){
exp.printStackTrace();
}finally{
try {
if (input!= null)
input.close();
}catch (Exception ex) {
ex.printStackTrace();
return sb.toString();
/** Send an HTML Email with the specific subject to specfic toAddress based on specified fromAddress & Smtp Hostname

boolean flag = false;
try {
String to = toAddress;
String from = fromAddress;
String host = hostName;
// Setting Mail properties
Properties props = new Properties();
props.put("mail.smtp.host",host);
props.put("mail.debug","true");
// Getting a New Instance Generated by the API
Session session = Session.getInstance(props);
NOTE: a Mail Session could be configured and could be got from the Container via JNDI
which could be a better practise.
// Instantiate a message
Message msg = new MimeMessage(session);
//Set message attributes
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
// Setting Subject Type
msg.setSubject(subject);
msg.setSentDate(new Date());
// Setting Content Type
msg.setContent(contentType);
// Set message content
msg.setText(htmlMessage);
//Send the message
Transport.send(msg);
flag = true;
}catch (Exception mex) {
// Prints all nested (chained) exceptions as well
mex.printStackTrace();
return flag;
public static void main(String args[]){
SendMail sm = new SendMail();
String htmlMessage = sm.readFile("myHtmlFile.html");
boolean flag = sm.sendMail("[email protected]","[email protected]","your.smtp.server","EMail SubJect",htmlMessage,"text/html");
if(flag)
System.out.println("MAIL SENT SUCCEFULLY");
else
System.out.println("MAIL SENDING FAILURE");
}NOTE:

Make sure you inculde javamail & java activation libraries.
Hope that might help :)

Hello,
I have a question about parsing HTML files. Usually when I get an HTML file and I need to find all the text in it I do this. This stuff just collects all of the hyperlinks and ignores all the html tags just keeping the actual text. It's fine for smaller files but occasionally I'll hit a large online text file and it will work but its way to slow for large files. I don't need to do all of this HTML tag stripping however for text files. Is there a way to still grab all the text without doing any tag searching to make it faster?
thanks,
private void find() throws IOException
//Really slow for large text files. Need a way to just use a regular scanner on an internet text file
new ParserDelegator().parse(new InputStreamReader(myBase.openStream()),
new ParserListener(),
true);
* Inner class for processing all "<a href.."> tags when reading a base URL.
private class ParserListener extends HTMLEditorKit.ParserCallback
final String IGNORED_LINKS = "^(http|mailto|\\W).*";
public void handleStartTag (HTML.Tag t, MutableAttributeSet a, int pos)
if (t == HTML.Tag.A)
String href = (String)(a.getAttribute(HTML.Attribute.HREF));
//System.out.println(href);
//System.out.println(href.matches(IGNORED_LINKS) + "\t" + href);
if (! (href == null || href.matches(IGNORED_LINKS)) && !myURLs.contains(href))
myURLs.add(href);
//TODO fix
if (t == HTML.Tag.TITLE)
String title = (String) (a.getAttribute(HTML.Attribute.TITLE));
if (!(title == null))
myTitle = title;
else myTitle = "No title was found";
public void handleText (char[] data, int pos)
myText.append(" ");
myText.append(data);

My question is. If I know an html file is actually just a txt fileThis isn't a question. HTML files are text by definition.
is it possible to look through it (maybe use something similar to a regular scanner) without doing anything with html.That depends on what you mean by "doing something with HTML". You can certainly read it one line at a time. -
Corruption of non-HTML files with oracle_smp_chronos.js script element
When serving a JavaScript file through the portal, the server always appends:
<SCRIPT SRC="/oracle_smp_chronos/oracle_smp_chronos.js"></SCRIPT>
which causes a JavaScript syntax error in the browser.
Why does it append this HTML element to a JS file ?
How can I stop it ?
MikThe script only uses the event to find the HTMLEntity where the handler was originally called - it then uses this reference to locate the original handler which it replaced - and calls it.
Things really start to get messy when you use a LINK to submit a form....the original javascript probably does something like this:
if ((!form.onsubmit) || form.onsubmit()) form.submit();
Chances are, the original onclick handler did not pass the event, and the event does not get passed to form.onsubmit(). Even if it did that just pushes the error further down - because oracle_smp_chronos.js replaces the onsubmit for forms too. So what happens is:
user clicks link, this calls Oracles handler
Oracles Handler does its thing, then identifies the link from the event and calls the original handler
Original Handler calls form.onsubmit, passing on the event
but since the onsubmit method has been replaced, its actually calling Oracle's handler again, which does its thing again, then sees that the event references the LINK (not the form) so it calls the backed up Original handler
Original Handler calls form.onsubmit()
...and so on until the stack overflows.
In the version I've got, this only happens where oracle_smp_chronos thinks the browser is Netscape Navigator or one of its descendants. There is a seperate branch of code for MSIE - it uses 'this' to track back to the original code, ignoring the event. Ironicaly, the MSIE code runs fine in Mozilla 5, and any version of Firefox (I don't have a copy of Navigator v4 to test) so a better solution would be to change the browser identification code to treat everything as MSIE

Struts portlet Instance Label problem: Appending the html tags in jsp
I have created a struts portlet and given it a Instance Label. I have used struts-adapter-html.tld tld in my jsp which is referenced by my struts portlet. But the problem with using this taglib is that the portlet Instance Label is appended to all the html tags on the JSP as a result of which when the page is submitted, formbean will not pick any of the values as the name will not match. Has anyone has faced this kind of problem? How can I prevent the appending of the HTML tags with the portlet Instance Label?
Please help me overcome this problem..
Thanks in Advance ...1. To begin with, I would not recommend NOT to append portlet instance label to html tags. This is very much required. Take atleast 2 scenarios. If you dropped 2 instances for Same Portlet like News/Articles portlet etc on same page, you need to identify the html fields uniquely for each portlet so that backend java code works properly. Also if you have 2 different portlets assuming you did not give any name to form tag, and if you have html tags with same name, you need to identify them. Remember when portal or desktop is rendered, it is one big html file with html fragmetns from all .portlets files. So I am not sure if there is any option at all, to avoid the appending of instance label value to html tags.
2. Coming to your usecase, I did had this problem once in 8.1 SPxx long back. All we did was, in the back end code, using BackingFile we could get the intance label value of the portlet. We can get this in pageflow also. Then pass this value and manually append this value to the html field of interest. In your case looks like you have Struts and tld tags. See somehow if you can get portlet instance label in jsp file and pass around to your tag lib code in request parameters etc. This is just one idea. I am not fully aware of your code, so try something along these lines.

How to reduce size of html files with JAVA?
We have html files full of tab char, carriage return, blank space between tags etc. We need to reduce the size of this files.
HTML files are automatic generated by an engine and we cannot operate on it.
Those files are in a solaris environment and we need to launch or to schedule something that can clean the files in this environment. The only tools we found are for Win environment so we toughth to make some java classes that parse HTML and clean the files.
Does anyone know how some tool or the way to clean a file in java?
Thank YouSomething like this can reduce the number of spaces between tags in the body of the file:public static final String readTextFromFile (File f)
StringBuffer fileText = new StringBuffer();
if (f != null && f.exists() && f.isFile())
try
FileReader fr = new FileReader(f);
BufferedReader br = new BufferedReader(fr);
String s;
char c;
boolean inTag = false;
boolean lastWasSpace = false; // so we don't have a million spaces in a row
boolean inBody = false;
while ((s = br.readLine()) != null)
s += " ";
s = searchReplace(s, " ", " ");
if (!inBody)
int bodyStartPos = s.indexOf("<body");
// if not in body yet, reloop
if (bodyStartPos == -1)
continue;
// start it off
else
inBody = true;
s = s.substring(bodyStartPos);
for (int i = 0; i < s.length(); i++)
c = s.charAt(i);
if (c == '>')
inTag = false;
else if (c == '<')
inTag = true;
else if (!inTag)
if (!(c == ' ' && lastWasSpace))
fileText.append(c);
if (c == ' ')
lastWasSpace = true;
else
lastWasSpace = false;
if (br != null)
br.close();
if (fr != null)
fr.close();
catch (Exception e)
System.err.println(f + ": Error reading file");
return fileText.toString();
}
