Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

How can I get Java to fill out form on web page and submit?

I need to write a Java program that will submit a HTML form. I tried using POST already, but the only response I got back was the source code for the page itself. Looking more closely, I realized that there is a PHP script that will actually take the data from the forms and use it. How can I get Java to enter the data on the forms automatically and then run this PHP script? I don't need code, just a pointer in the right direction should do.
Thanks in advance,

If you are writing a program to submit a form,how come the PHP script come out of nowhere ? At this momemnt you are just writing some Java program,isn;t it ?
My feeling is you are trying to edit some pre-written code.
Is it ?
Thanks.

Hi,
Based on your code, I see your code related to
iTextSharp Pdf.
iText is a third party library to create PDF originally written for java. iTextSharp is
the C# adaptation of that library.
Question regarding iText are better asked on the iText forum, rather than the Microsoft Forum:
http://itextpdf.com/support
Thanks for your understanding.

How can I get the cursor's position in a opened file and display a menu?

Hello,
I want to make a program by which I will be able to display a panel/pops up menu at the corsor's current position, (In any text/doc file or in the desktop, we can display a menu by right click of the mouse.) Now I want my program to do the same task.
More clearly-
1. First I would save some words or sentences in a file(aa.txt).
2. Then I would open another text file/ a word/ excel/ or any other editor( bb.txt / cc.doc / dd.xls / ee.html ).
3. While editing or writing something in the opened file, if I click the right mouse button/ press a key (ctrl+space), a menu will appear containing the sentences I saved in the file(aa.txt) previously.
My program will tell me the cursor's position in bb.txt / cc.doc / dd.xls / ee.html that i opened. And display a menu. my problem is not reading / writing in a file.
My problem is how can I get the cursor's position in a opened file display a menu at that position by a mouse/key action*.
Would you please help me on this regard.
Thanks

How can we get ADFSecurity work when used in OC4J, OID and OAM?

I am getting error in http server log "mod_oc4j: Response status=499 and reason=Oracle SSO, but failed to get mod_osso global context."
But I am not using Oracle SSO and my client doesn't want to use it either, I am using OAM SSO(CoreIDSSO) in my configuration. Please read the details below.
I am using ADFSecurity in an app that is protected by OAM. To migrate ADFSecurity permissions from
system-jazn-data.xml to OID, I used JAZNMigrationTool to populate OID with Grantees and Permissions. OAM gives login page, and authentication works fine.
But ADFSecurity is not working. ADFComponent Delete button is enabled even for roles that dont have permissions for the iterator delete.
- The app works fine when I use without OAM. ADF Security permissions work fine.
- The app works fine when used with OAM, but with ADFSecurity disabled (enforce=false).
- When I enforce ADFSecurity alongwith OAM, ADFSecurity is not working.
In the doc "Oracle Containers for J2EE Security Guide b28957", there is a mention of use of CoreIDPrincipal for permissions. Our OID Permissions entries show
LDAPRealmRole for attribute orcljaznprincipal. I am not sure if this could be the reason.
We have configured AccessServerSDK for the SOA instance and have policy for the urls in the policy manager. We have entries in orion-application.xml, orion-web.xml and system-jazn-data.xml as per the documentations.
How can we get ADFSecurity work when used with OID and OAM?

Have you been able to successfully integrate OAS with OAM & OID? We have similar requriement and so far we have not been able to get it working.
We have application specific roles which we map to OID roles using orion-application.xml.
Any pointers to achieve this would be greatly appreciated.
thanks,
Dipal

If streaming music when connected to your carrier's cellular network, it uses cellular data.
Only the music you purchased from the iTunes Store can be streamed unless you have purchased iTunes Match.
If there is a slow down at the server where the music is stored or high traffic, steaming can be paused. You can also download a song from the iTunes Store cloud to your iPhone so it doesn't need to be steamed.

Had you never backed up the phone before? When you saw the iTunes logo and cable, the device was in recovery mode. The data was already lost. The only way to recover from that is to restore the device, which will delete all of your data. You will only be able to restore to your last backup, whenever that was. Sorry this happened, but this highlights the importance of doing regular backups. The backup is the only protection you have against a problem like this.

How can i get apps with out using credit card info because i do not have a card ?

how can i get apps with out using credit card info because i do not have a card ?

Yo Chris. I've been following your answers to different threads and quite frankly, you're very keen in answering everybody regarding this stupidity that Apple has brought upon its customers. Kudos to you. But the problem is, most of the time, in some devices, your solution doesn't work because the NONE option is not there. The same goes for me.
Meanwhile, I found a temporary workaround for the iPhone 4s, iPad 2 and iPod Touch 4th Gen.
Register a free Apple ID from the iCloud Settings.
Go to Settings>iCloud>Account>Tap Payment Information on the Storage Plan Category.
Fill in the other boxes and choose "None" on Credit Card Information.
That's it! Hope I helped those who still couldn't find the "None" Option.
Must be running IOS 5.0.1 though, else there would be no iCloud.

How can I get Colorful Tabs to use separate colors for 2 different gmail accounts?

Running Firefox 29.0.1 on iMac OSX 10.9.3. I have multiple Google accounts: 2 gmail accounts and 1 Google Calendar. The Add-on Colorful Tabs will allow me to choose a color for one gmail account , but it also uses that same color for the other gmail account. How can I get different colors on 2 different gmail accounts?
Also, Colorful Tabs is also doing the same thing for my homepage (google.com) and my google calendar. How can I get different colors on these 2?

I personally use "Fabtabs" for my mozilla FireFox.

How can I get Sender Display Name using Get-MessageTrackingLog?

Hi, could you please help me. We have got a monitoring system at work which monitors some devices, so if something wrong happening with these devices email is sent from MASTER email (Customer Name <[email protected]>) to us. I'm trying to get a list
of all emails of that monitoring mailbox using PoweShell command
Get-MessageTrackingLog and export them to CSV file. In the end of the day I need CSV file with 3 columns: TimeStamp, MessageSubject and SenderDisplayName! Yes, I need Sender Display Name cause all emails are sent from one MASTER email
(Customer Name <[email protected]>) and only difference between them is sender Display Name which is cexactly what I need.
This is the code I'm using:
Get-MessageTrackingLog -EventId Receive | Select Timestamp, MessageSubject, Sender | Export-CSV C:\NagiosAlerts.csv
–NoTypeInformation
So how can I get sender Display Name(Customer Name) using Get-MessageTrackingLog insted of Sender email (<[email protected]>)?

The DisplayName is not recorded in the Logs only the EmailAddresses are so there Is nothing you can do with Message Tracking to get this the way you want. You need to look at another property may soureIP or include something in the Subject
of the Email (eg a customerId in the Subject is a much better option) to give you some differentiation. Otherwise you need to access the Email directly from the Mailbox it was sent to and then extract the DisplayName from the message (or use a journaling
on those emails etc)

How can I get firefox to execute perl scripts from local files

I have created perl scripts on my local host (file type ".pl").
In MS Windows I have associated that type to a perl interpreter installed on my local host.
IE allows me to create links to them and to execute them (after asking for permission).
How can I get firefox to do the same? It doesn't seem to allow me to add application types, only to change those that are already defined. As a result, in firefox, they just show up as text, instead of being executed.

First guess is that you did not use an .html extension on the file. The file may well be ''name.html.txt''
