Java.lang.NullPointerException when shutting down database
Hello
I am using sqldeveloper 1.5.1.
I created a connection as sysdba . When I click on "Shutdown" button (in "manage database"), I get the following exception :
java.lang.NullPointerException
at java.util.Hashtable.put(Hashtable.java:396)
at java.util.Properties.setProperty(Properties.java:128)

at oracle.dbtools.raptor.status.StatusPanel$1.doWork(StatusPanel.java:132)
at oracle.dbtools.raptor.controls.progress.DelayedProgressRunnable$RunnerThread.run(DelayedProgressRunnable.java:163)
Is it a known issue, or how can I fix it ?

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

2003/04/01:21:41:22Failed 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?

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.

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 -

any thoughts...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. -

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.
JayProblem 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).

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

I keep getting the below error in the log file when the process is complete, does any one has this error before?

Hi guys,
I'm getting a java.lang.NullPointerException (with no other details of error) when i try to write to a textfield on my GUI. the line: TF1.setText("F"); is where the problem is occurring. that line is within a loop ->
if(freq >87 && freq < 100)
System.out.println("Note =F" +freq);
TF1.setText("F");
the textfield has been constructed and initialised and given an initial value. what i need to happen is the string in the textfield to be constantly updated (overwritten) with the new string.
the initial value from TextField TF1= new TextField("", 10);
TF1.setText("blank");
works fine, but one the loop above is entered, the current frequency is printed to the command line and then "java.lang.NullPointerException" is thrown.
I'm struggling with this, and have a deadline to meet so I would much appreciate some help.The Gui class is this:

Java.lang.NullPointerException when trying to preview an iVew in EP
We have set up a portal federation with a BI portal as the producer and a enterprise portal as the consumer. When we try to do a preview on iView which is based on BW 7 based contents from producer portal, we get java.lang.NullPointerException. The 3x based reports are being displayed fine on the consumer side. I have put excerpt from the default_trace from producer portal that gives some error messages but I am not able to figure out where the problem might be.
Any help is greatly appriciated.
Thanks

E-Rec - java.lang.NullPointerException when creating a VacancyReq thru MSS
Hi,
While i try attempting to create a vacancy requisition thru MSS using start method, "Previous Request", i get to see an "java.lang.NullPointerException" internal server- error in the portal.
When i checked the error log in the backend in ST22, i see the error description given below,
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: " ").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
When there are many previous requisitions (previously raised) available for the Manager I.D iam testing, iam not sure why this error is showing up,
Has any one faced this issue before? can some one give any clues on the issue iam facing.
Info - I have hidden 2 other start methods available in standard thru configuration (Job & No Reference) from the manager grouping. But i have thorougly checked the configuration and there doesnt seem to be a problem with the configuration as such.
Thanks
G RajHi Raj,
We are also facing the same issue.If you provide us with a solution it would be of great help.
Thanks.
