Hi All,

I am creating a form like a Grid will be having some data, and if we select a row, details of that row will be displayed in the adjecent form.

I am able to show the values in grid and form, but when ever i am loading the page i want to show first recocrd on the grid is highlighted and the corresponding values loaded to form.

I am not getting the logic to show a row is selected, can you please help?

I am creating com.extjs.gxt.ui.client.widget.grid.Grid type grid and the Grid will have arguments as ListStore and ColumnModel.

Hi All,

I need your help. Let me explain the issue,

A XML file is need to parsed and data should be stored in database. So existing implementation is XML file inserted into a database table and fired a trigger on that table. The trigger is reading the XML content and storing the data into appropriate table.

What my idea is, with out inserting the XML file into database i am planning to use JAXB here. I will unmarshalize XML file and using DAOs i can store them into database.

But here i need to prove which approach is better? I need to find the CPU % usage and lapse time in both the cases. Can anybody help me here with you suggestions to find CPU% and lapse time in bothcases.

Hi Vijitha & Ankit,

Thank you for your reply.

Hi All,

I checked with a examination center and they said that they still allowing people to take 1.4 exam. The exam 310-035 SCJP 1.4, is it still conducted by SUN? I searched in SUN website but did n't found any information.

I found the solution. It is because of library files, they were got corrupted some how! i copied them and everything is fine.

Hi All,

I need to use jar.exe where java is not installed. A user downloaded a application, that application need to jar some files and process them (So there is no guarantee that user has installed java). I want to add the jar.exe and jli.dll in my installer itself. But i am unable to find jli.dll any where. Also what configurtion i need to do so that the user side my program run without any issues.

yes Ove, i need to read them from a java program. So the location is a central location to all the files.

Thank you verymuch Rob. I am sorry for not clearly writing my problem.

I am doing this from a batch file. This batch file should be in the c:\upload folder. Thatsway i clearly mentioned the path names.

As unjaring will be done at server side. Can i do something while unjaring, so that the specified files can be moved to particular folder?

Hi Folks,

I am sorry if i am posting my question in wrong area.

I am creating a jar file using a batch file. It will create the jar files
jar -cvf0 c:\upload\temp\afile.jar c:\datafiles\*.xml c:\datafiles\*.doc

it is creating "afile.jar". I need to unjar this file in a UNIX meshine.
I copied it to UNIX meshine and unjared it. It is creating 2 folders in UNIX meshine named "c:" folder and "datafiles" folder and coping all XML and DOC files there.

What i need to do, to have the files in the same folder where i unjar them or move to some specified folder of UNIX meshine?

I am using AES algorithem.

Key Generator code is: --------------------- KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(128); //128 bits key = kgen.generateKey(); Encryption: ---------- Cipher ecipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); //paramSpec is a Initialization Vector ecipher.init(Cipher.ENCRYPT_MODE, skey, paramSpec); FileInputStream in = new FileInputStream("c:\\encryption\\Source.zip"); FileOutputStream out = new FileOutputStream("c:\\cipher\\cipher.enc"); OutputStream cout = new CipherOutputStream(out, ecipher); int numRead = 0; while ((numRead = in.read(buf)) >= 0) { cout.write(buf, 0, numRead); } Decryption: ----------- Cipher dcipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); dcipher.init(Cipher.DECRYPT_MODE, skey, paramSpec); FileInputStream fis = new FileInputStream("c:\\cipher\\cipher.enc"); InputStream in = new CipherInputStream(fis, dcipher); FileOutputStream fos = new FileOutputStream("c:\\encryption\\Result.zip"); int numRead = 0; while ((numRead = in.read(buf)) >= 0) { fos.write(buf, 0, numRead); }

Hi Folks,

I am facing a problem while encrypting and decrypting a ZIP file. The result file is corrupted.

If i encrypt .txt and .doc files, i am able to get them in decryption. But problem with ZIP files. What could be the reasone?

Yes, i did some mistakes. Your code is working. Thank you once again.

Thank you Ulf and Greg. But these changes are not made any difference, i am getting same exception. I am searching google for references, but they are using MD5 to encode and checking signatures also. I am confused can't we simply read from txt files and recreate the RSA keys? is it is not that simpler? folks please help!
