bla bla bla
kf = KeyFactory.getInstance("RSA");
pk = kf.generatePrivate(priServer);
cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.DECRYPT_MODE, pk);IMHO RSA is 2-keys algorithm => you cannot use it in cipher class
If u need encrypt use PBE for example
PBEKeySpec pbeKeySpec;
PBEParameterSpec pbeParamSpec;
SecretKeyFactory keyFac;
// Salt
byte[] salt = ...;
// Iteration count
int count = 20;
// Create PBE parameter set
pbeParamSpec = new PBEParameterSpec(salt, count);
// Prompt user for encryption password.
pbeKeySpec = new PBEKeySpec(pass); //String with
keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);
// Create PBE Cipher
Cipher pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");
// Initialize PBE Cipher with key and parameters
pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);
// Our cleartext
byte[] cleartext = "This is another example".getBytes();
// Encrypt the cleartext
byte[] ciphertext = pbeCipher.doFinal(cleartext);

Hi Timo,
Thanks for the reply,
If I understand correctly I need to apply to the weblogic server 10.3.5 + Sherman patch UPDATE1 patch #12979653 and patch #12917525. After this the ADF Runtime 11.1.1.5 installed in the Production environments will allow me to run my application that is running in ADF Runtime 11.1.2.1. right?
I'm working on getting this patches installed. Thank you very much for your help.
I run the test on my local server as a test class and as a web service, it worked perfect, nevertheless in the Production environment I got a interesting answer:

Java.lang.NullPointerException when trying to start UM

I get java.lang.NullPointerException when I try to start Unified Messaging using EM on a new Windows 2000 single-box installation. Has anyone enountered this problem?

I have also encountered same issue. Please let me know the solution in case you find it.
In fact after configuiring Oracle files as per the document provided at Oracle OTN site 'Collaboration handbook', I am unable to connect OID. As per log it says
2003/04/01:20:37:58[Oidmon]: Unable to connect to database, will retry after 20 sec
2003/04/01:21:20:21Starting Monitor Process, PID=2920
2003/04/01:21:20:21ORACLE_SID not set, setting to iasdb
2003/04/01:21:41:22Failed to fetch Process Table. ORA-12571: TNS:packet writer failure
I checked Listener, which was found ok, then I checked TNSPING, which executed ok.
I have dowloaded documents troubleshooting OID, but no success. The document itself says that architecture of OID is fairly complex and the log does not suggest much insight.
Any solution?
Regards,
Vipul

Java.lang.NullPointerException when doing SQL on ms access

I am trying to perform Insert and delete commands on an access database and I continue to get a java.lang.NullPointerException when performing the action. Everything is fine when i do a Select * FROM..., I am able to read all of the information I ask for, but when performing the Insert/Delete commands I get the error. Any help would be appreciated, I will copy and past a portion of my code below. All of the fields and variable types match with what is in the database.
public void executeAddSecretary() throws SQLException{
String a,b;
a= txtSecLname.getText();
b= txtSecFname.getText();
statement.execute("INSERT INTO Contact_Sec (Sec_Lname,Sec_Fname) Values ('" + a + "', '" + b + "')");
System.out.println("updated Secretary");
public void executeDeleteContact() throws SQLException{
String a = "a";
statement.execute("DELETE FROM Contact WHERE Lname = ('" + a + "')");
System.out.println("deleted contact");
Thanks to anyone who can help me out.

1) Use prepared statement instead of statement.
2) Do like this ...
PreparedStatement prepStmt = null;
try
     String query="INSERT INTO Contact_Sec (Sec_Lname,Sec_Fname) Values (?,?)");
     prepStmt = connection.prepareStatement(query);
     prepStmt.setString(1, value1);
     prepStmt.setString(2, value2);
     prepStmt.executeUpdate();
catch (SQLException e)
     throw e;
catch (Exception e)
     throw e;
finally
     try
          if (prepStmt != null)
               prepStmt.close();
     } catch (Exception e) {}
     try
          if (connection != null)
               connection.close();
     } catch (Exception e) {}
}3) If you still get the null exception then put step wise System.out's
and debug it.

please let me know if you have configured any RPS for the same.i faced a similar issue while i was trying to create an instance taken from oracle export dump taken from one of our client.our error got resolved when we changed the web profile to PROD. More often than not this is an issue with the webprofile. try changing the web profile one by one from dev to test to prod and kiosk.
if none of these resolves the issue, try ruuning version app engine program. this will update the ppltools version. in correct version may also some times cause this issue.
Please let me know if you have configured ldap.

Java.lang.NullPointerException when trying to compile

Hi everybody!
I'm trying to compile a file using javax.tools.JavaCompiler but I get a java.lang.NullPointerException when running the program.
Here is my code:
public boolean CompExecFile(File filename){
 boolean compRes = false;
 try {
 System.out.println(filename.getAbsolutePath());
 JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
 StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null); //line where I get the error
 Iterable<? extends JavaFileObject> compilationUnits2 = fileManager.getJavaFileObjects(filename);
 compRes = compiler.getTask(null, fileManager, null, null, null, compilationUnits2).call();
 fileManager.close();
 if (compRes) {
 System.out.println ("Compilation was successful");
 } else {
 System.out.println ("Compilation failed");
 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 return compRes;
 }There error on the line "StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null);":
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException+
I've seen several examples using the parameters "null,null,null" but I don't know if it's good :(
Many thanks for your help.

I've found something which could maybe be what I need to do but I'm not sure:
// Build a new ClassLoader using the given URLs, replace current Classloader
ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
ClassLoader newCL = new URLClassLoader(myClasspathURLs, oldCL);
Thread.currentThread().setContextClassLoader(newCL);
System.out.println("Successfully replaced ClassLoader");
Class fooClass = newCL.loadClass(appClass); //which replaces the line "Class<?> tempFileClass = Class.forName("TempFile");" ?!Is that what I need to do?
EDIT: I've tried that but I still have the same problem:
 File classFile = new File ("TempFile.class");
 ClassLoader oldCL = Thread.currentThread().getContextClassLoader();
 ClassLoader newCL = new URLClassLoader(new URL[] {classFile.toURL()}, oldCL);
 Thread.currentThread().setContextClassLoader(newCL);
 System.out.println("Successfully replaced ClassLoader");
 Class tempFileClass = newCL.loadClass("TempFile");
 Method main = tempFileClass.getMethod("main", String[].class);
 main.invoke(null,new String[0]); Edited by: Foobrother on Jul 28, 2008 8:18 AM

Other times, it works fine. Anything I might have done wrong in installing this guy? Any thoughts?
Thanks, Michael

I'm agree ... His behavior is very strange.
At the first time, I decompressed zip file into a new dir and at the first run I agreed to import setup from previous version. From the beginning the v2.1 worked wrong.
After that, I removed all, new and previous versions. I deleted sqldeveloper folder and also service folder (under \Documents and Settings\...\Application data\...)
Also I searched into registry ...
Nothing to do ... also new installation hangs ...
So, perhaps I have to wait new release ... (perhaps the exceptions or the environment conflict will be fixed).
Thanks again.
Regards.
PS: Please, if you have other suggestions, let me know. Many Thanks.

Java.lang.NullPointerException when uploading a template using XML Admin R

Morning All,
i have some issue when i try to upload my templates in Oracle Applications.
I was able to upload just one of my templates becasue on some of them i get the java.lang.NullPointerException from the system.
Anyone has alredy experienced something like this? any idea/workaround?
Thank You, Pier Paolo.

hi there and thanks for your answer :_)
actually the two files are completly the same at least concerning the text, font and graphics i have been used (ofc what is written in there is different).
I noticed just a small difference in terms of kb between the two files...so i made a copy of the one that has been uploaded correcly and i have replaced the body with the one i needed. Now it's working fine...so it seems that there was some sort of difference in the file itself and not in what it was containing.
Dunno if you can help me out on this...but have you noticed some characters or form items that are not printed out correcly once you publish the report? (i have some problem in showing the quote and the CheckBoc Form field)
Thank You, Pier Paolo.

Urgent - java.lang.NullPointerException when deploying a WAR file

Hello
I am trying to deploy a WAR file on 9iAS rel 2 using the Enterprise Manager. On the web page, I provide the .war file along with application name and url mapping. When I click on deploy, i get an error back which just says java.lang.NullPointerException. There is no stack trace.
Until now, I have been working on my own PC using tomcat, and the war file works fine in tomcat.
I am presuming that there will be a log file where more information will be available, but I do not know where the log file is kept. The Oracle 9iAS is installed on Solaris.
Any help with this would be greatly appreciated.
Thanks.
Jay

Problem Solved
The problem was the web.xml file which contained some elements that are only valid for servlet 2.4 (used on tomcat) but not on 2.2(used in oracle).
