How to get the contents of jar file?

Hi
is there any way we can see the contents of jar file.(Since it is similar to zip file can we unzip it and see the contents)

You can use:
this->getClass().getResourceAsStream("/something.txt")
where 'something.txt' is a file inside your .jar

thanks masijade,
i have filter the file chooser for only text files,
but i still don't know how to use FileReader to put text file content to the text area (ta) ..
please tell me how and where to use it..How? -- See the IO Tutorials on Sun for the FileReader (and I assume you know how to call setText and append in the JTextArea).
Where? -- In the actionPerformed method (better would be a separate thread that is triggered through the actionPerformed method, but that is probably beyond you at the moment), of course.
Give it a try.

You will not be able to use a normal InputField to upload file contents. This is not allowed by the browser security model. You must use one of the upload specific UI mechanisms - the FileUpload UI element or as of 7.01 ACFUpDownload or FlashIslands.

I am thinking of buying a MacBook Air and am wondering how to get the content of my iPad into iTunes.

I have iTunes on an old pc and am thinking of buying a MacBook Air. I am wondering how to get the content of my iPad on to the Mac as I know that sync only happens in one direction, from pc to device. I assume therefore that when I attach my pad to the new Mac it will sync to an empty iTunes and I will have lost all the content of my pad. I know I can restore purchases, but what about contacts, calendar, photos and music not purchased from apple. I have a fairly recent backup on a pen drive but it is a usb2 device and is formatted for a pc. Any advice would be appreciated.

Do I copy my media library or from a backup. I have a backup on my pc and on an external drive. This drive is usb2 and formatted for windows so I can't connect it to a MacBook Air to make the transfer. Equally I don't think there is a way to connect the 2 computers via a cable ie usb2 one end and usb3 the other. Will the computers talk to each other via wifi if I enable home share although I think this is only for music which still leaves contacts, mail etc.
I am sorry to be such an ignoramus but any further help would be appreciated.

WD ABAP: How to get the contents of selected table lines?

Hi,
I'm trying to figure out how to get the contents of table lines back from the UI. I display a table with several lines of data. The user selects some rows. I want to move the contents of the selected rows to another table. I have a context attribute, say DATA, with attributes FIELD1... FIELDn, using a DDIC structure. These are bound to the table UI element and the corresponding table columns. To get the selected rows, I use wd_context->get_selected_elements(). This works, but what I get from this method is references to if_wd_context_element. How do I know which row (row number = ?) this corresponds to? And how do I get the actual data? I want a structure with FIELD1 = value1 FIELD2 = value2 etc. My context attributes FIELD refer to table columns, but I'm looking for the table line...
Can somebody help me?
Thanks,
Ira

Hi Ira,
wd_context->get_selected_elements() returns WDR_CONTEXT_ELEMENT_SET which is a table type of IF_WD_CONTEXT_ELEMENT. You can loop through the WDR_CONTEXT_ELEMENT_SET, get into variable say node_elelement which is of type ref to If_Wd_Context_Element. Then you could use the method GET_STATIC_ATTRIBUTES of If_Wd_Context_Element which returns a structure with values of all the attributes in the selected row.
If you need the row number, while populating the node you could have an additional attribute called rowno and populate it correctly. When you select the data using method GET_STATIC_ATTRIBUTES, you would get the appropriate row number.
Regards,
Srini.

How To Fetch the Content of a File from Client's PC?

In my JSP I have this:
<input type="file" name="filename">for visitors of the web page to browse their PCs' directories to select a file to upload (when the Submit button is clicked).
What appears in the text field will be a file name. How do I get both the file name and the content of that file to be saved in the database?

From http://www.htmlhelp.com/reference/html40/forms/input.html:
A form that includes a file INPUT must specify METHOD=post and ENCTYPE="multipart/form-data" in the <FORM> tag. CGI libraries such as CGI.pm allow simple handling of such forms.
Form-based file upload is unsupported by many currently deployed browsers. Authors should provide alternative methods of input where possible.
The following example allows the user to upload an HTML document for validation:
<FORM METHOD=post ACTION="/cgi-bin/validate.cgi" ENCTYPE="multipart/form-data">
<P>Select an HTML document to upload and validate. If your browser does not support form-based file upload, use one of our alternate methods of validation.</P>
<P><INPUT TYPE=file NAME="html_file" ACCEPT="text/html"></P>
<P><INPUT TYPE=submit VALUE="Validate it!"></P>
</FORM>
Your servlet would then have to process whatever data is put into that parameter. You can look at O'Reilly's servlet utilities, or one of the other other links here:
http://www.google.com/search?q=java+servlet+file+upload&sourceid=opera&num=0&ie=utf-8&oe=utf-8

     s1=sh.getCell(0,i).getContents();
     s2=sh.getCell(1,i).getContents();
     s3=sh.getCell(2,i).getContents();
     s4=sh.getCell(3,i).getContents();
                         table.setName(s1);
     table.setAddress(s2);
     table.setDesignation(s3);
     table.setDummy(s4);
     al.add(j,table);
     j++;
wdContext.nodeTable().bind(al);

How to get the URI of a file in a WAR

Hi all,
I have a deployed WAR.
One of its files need to get the URI of another file in this war.
In exploded format, application.getRealPath(thefilename) would do the
trick. But it failed if the application is deployed in WAR archive.
What's the workaround ?
Note that I need the full path of the file since I need to read its
content and parse it as XML using DOMParser that requires the full URI ..
Any help appreciated ..
mona

I have a piece of code that does this that looks like this:
InputStream inStream =
<ServletClassName>.class.getResourceAsStream("/foo.xml");
InputStreamReader inReader = new InputStreamReader(inStream);
And 'foo.xml' is put in the classpath either by placing it in a .jar file in
the WEB-INF/lib directory or by placing it in a .jar file that is deployed
with the webapp .war file in an .ear file and then referenced by the
'Class-Path:' manifest directive in the META-INF/MANIFEST.MF file of the
webapp.war file. Both ways work. I would think you could put 'foo.xml' in the
WEB-INF/classes directory and that work work, too. But, I haven't tried that.
