How to save HTML

How to save html response when execute a siebel load test.

First at all excusme for my english.
I need help to manage html response. I use OpenScript Version: 9.3.1.0 Production.
When i execute a siebel load test, some of the VU returns the error "12152 the server response could not be parsed". Mi boss asked me an image or html response to analize the error. But i dont now how to get it.
I search in all logs but i didn´t find nothing usefull.
Anyone know how to save the html response when execute a load test?
Thanks.
Gabriel.

"First at all excusme for my english."
=> are you french? I am! So no problem of course ;-)
Which ATS version do you use? Because starting with 12.1, you have a better VU Logging capabilities.
From the OLT user guide:
The virtual user logs window has the following toolbar options:
Open - Opens an existing virtual user log.
Save as CSV - Exports the current VU log to a comma-separated value file.
Clear - Clears the virtual user logs.
View Text - Displays the source HTML for pages accessed by the virtual user.
Render HTML - Displays actual pages as accessed by the virtual user.
Auto Display - Displays pages as they are received by the viewer.
See if it can help.
If not, maybe you could implement some logics in OpenScript, but i wouldn' advice that.

The client should probably parse the html that comes down, and look for <img> links, and request those of the server as well.

How to save .html page in iBooks on iPad

I'm on my works intranet site that holds all of our policies and procedures. The links to each specific policy open has .html and not a PDF ( which it does or at least did at one point on my partners ipad that was running an older software version). How can I take that that page ( that specific policy or procedure) and save it in iBooks on my iPad?
Thank you

That poster seems to be referring to a technique used for adding webpages to ebooks created by using the iBooks Author app. I think he misread your question and thought he was in the forum for iBooks Author instead of this one.
You can't do anything with widgets on your iPad.

How to Save HTML page in Apex application into our local Windows Box

Hi,
I am having one HTML page in my Apex Application. I want to download this page into my Local Windows machine. How to do this?
Thanks
Yash

I am having one HTML page in my Apex ApplicationWhat did you mean by this ?
<li> If you meant an application page, then they are anot stored as html file anywhere as the page that you see is generated at the run time only, however you can can save that run time page , but its of not much use.
<li> If your intention is to save/backup an apex page, go to the page and export it . This generates a SQL file which you can import into any other apex application and recreate that apex page.
<li> You can also export the entire application as a single file too.

How do I download and saves html files off my website to store and save using Dreamweaver CS3?

How do I download and saves html files off my website to store and save using Dreamweaver CS3?
I need to save all files from web and store onto a drive to reupload to a new domain name. I use Dreamweaver CS3.

First define your Local Site folder in Dreamweaver. DW will use this folder to store your site files.
Go to Manage Sites > New or Edit site. See screenshots.
Servers: Enter your remote server's log-in details. When complete, hit TEST to see if the connection is working. If all is well, hit SAVE.
From the Files Panel (F8), click on Remote Server to show the files that are currently there. Click the green Down Arrow to GET files from remote server to your local site folder.

How to save diagramm in HTML format or PDF it

how to save diagramm in HTML format or PDF it

You have two alternatives. First of all, there are many utilities, some of them free that can put a "printer" on your printer list that really writes a PDF file. The one I use is free, called CutePDF. Once you have one of these installed, saving to PDF is as simple as print the diagram, choose the printer associated with your utility, then name the file.
I'm not sure if it is in your version of Designer, but all of the latest versions of Designer have a "publish diagram" utility. Just drop down the Utilities menu from the RON or the Design Editor. The bottom selection should be "Publish Diagrams...", which will open a dialog window. Choose the diagram(s) you want to publish, select Publish to File, enter a file name, and select a graphics format from PNG, GIF, JPEG, BMP or TIFF. You can easily add the file to an HTML page inside an <IMG> tag.

How to save JList items!

hello,
i m creating a class that has three JList components.
My problem is how to save the each JList items into a seperate logfile(ie. text file).

More info required:
What are in the JList? Strings? Custom objects?
Do you know basic file IO?
http://java.sun.com/docs/books/tutorial/essential/io/index.html
What you will need to do is get the model, ilterate over each element, then write that element out. If the element is a string, then that is easy, just create a FileWriter, and write the string, followed by a new line.
If it is a custom object, then the task is harder, and you need to decide how that object should be represented.
If you are after a computer readable view of the model, rather than a human readable, which can easily be read by Java back into a ListModel, then you want to look at XMLEncoder and XMLDecode, or the Serializing Objects tutorial.

I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

Hi,
If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
send it to you (sorry, I won't, it's copywrited).
If you cannot get this VI anywhere, you'll need to figure out the BMP file
format yourself. It's not too complicated, but still could take some days.
Perhaps someone figured it out before LV5.1 was released.
Regards,
Wiebe.

Hi,
Yes, you need store data to table, and fetch it when page is opened.
Simple way is create table with few columns and e.g. with CLOB column and then create form based on that table.
Then modify item types as you like, e.g. use HTML editor for CLOB column

Thanks for ur reply
Basically that html file is Excel file only
For view purpose saved it as html b'coz it is using in site(This part is mainetainied By US )
I need to download that file from site(Iam from India)
extract some data from that For that pupose i tried with htmlparser but it is not sovling problem completely.For that purpose i moved towards JExcelAPI .
Manually i saved it as .excel file then it is accessible with JExcel API
If i follow procedural way ie above method then its saving as excel file and looking as Excel file but when iam accesing that file as Excel file then it is giving Exception isOLEException
If i access manually convereted file then it is accessible.
Iam sending source URL
Look at this ::http://www.sttpc.com/reseller/price.htm
Procedural Code As Follows:
BufferedWriter out = new BufferedWriter(new FileWriter("c:/Excel/price.xls"));
BufferedReader in = new BufferedReader(new FileReader("C:/html/price.htm"));
String str;int c=0,r=0;
while ((str = in.readLine()) != null)
out.write(str);
n.close();
out.close();

Another option is save the file as a CLOB in a database column. But I'm not aware of doing that too.
Please guide me.
Thanks in advance.
Surangi.

See Steve Muench's Not Yet Documented Example #85 at http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html#85. While this is for 10.1.3, this is still relevant for 11g. Steve's example is for uploading to a BLOB - same thing for a CLOB. Once your data is in the database, you can use the DBMS_LOB package to write the file to a directory on the database server, if you like.
Also the Developers Guide is your friend - Chapter 9.9 in the Fusion Web User Interface Developers Guide for Oracle ADF 11g, or 19.6 in the ADF Developers Guide for Forms/4GL Developers for JDeveloper 10.1.3.
