Java.lang.NullPointerException still in the beta 2
I opened a class with 322 lines of code, press CTRL+A (select all) and then CTRL+C (copy to clipboard) and gives me the exception:
"Copy" did not complete normally. Please see the log for more information.
java.lang.NullPointerException
This error was already reported in the beta 1 of the Flash Builder 4.7 so seems that still remains in this new release.
Hi,
Could you please send a sample snippet or class to [email protected] ? It will help us reproduce this issue.
Also, please attach log file (Location: yourworkspace/.metadata/.log)?
Thanks,
Radhakrishna

Hi,

as i create a fileupload and i wish to get the file name and the pdf, then i to run and deploy it but i get <b>java.lang.NullPointerException</b>
the code are as below when i click on send email button

Near the begining of the method foo is initialised to null.
A load of conditional statements follow in only one of which foo is instantiated.
If this condition is not satisfied foo will remain null.
If that happens then you will get the error that you're getting on line 239.
Essentially all the conditions before the above mentioned condition would have to evaluate to false for foo not to remain null by the time line 239 is executed.
Line 239 is executed regardles of any of the conditional statements in your method, i.e. regardless of whether null is instantiated or not, in which case it remains null - hence the NullPointerException. -

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 -
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.

Uncaught Exception: java.lang.NullPointerException
Hi,
My BB 8220 flip has always had battery problems. Lately the battery dies after only 8 hours in standby mode. The last time it died was two days ago, and after four hours of charging it finally turned back on - only to have the error 'Uncaught Exception: java.lang.NullPointerException' showing on the screen. I have noticed that now the Call Log does not work for Incoming, Outgoing and Missed calls. The SMS has also mysteriously disappeared so I am unable to send and receive texts. My address book is still intact. I don't have a data plan so I do not have any extra applications on the phone, simply what it came with. I have tried to reboot (removing battery) a few times, but the error has not fixed itself.
Any simple ways to fix this error, or is my phone beyond repair?
Solved!
Go to Solution.Hi and Welcome to the Forums!
Given your description, I advise an OS reload or upgrade. From a PC, you can install any OS package to a BB via this procedure:
http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
Note that while written for "reload", it can be used to upgrade, downgrade, or reload -- it all depends on the OS package you download and install to your PC. You can even use a different carriers OS package by simply inserting, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML. Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

Unexpected exception with file: java.lang.NullPointerException
Hi :)
Still a Newbee
Geting the message Unexpected exception with file: java.lang.NullPointerException
Have traced the error down with the use of System.out.println(a sequential number); but having got it down to bReader.close();, I think, I'm not understanding why. I think it has something to do with the line while (text != null){
Don't fully understand yet as a newbee, but one can only learn. Like my other error (I once spent six hours on a pair of {}!!!! we all learn) I've spent two evenings now resarching and trying to solve this, so a bit of help would be very much appreciated.
Error occurs after System.out.println(7);
Code
private void initialiseData()
String text;
int size;
try
File file = new File("needleData.txt");
FileReader fReader = new FileReader(file);
BufferedReader bReader = new BufferedReader(fReader);
text = bReader.readLine(); // Read the first line to get the number of needles stored
size = Integer.parseInt(text);
while (text != null){
String type;
double length;

Data Federator Connection to R3 - java.lang.NullPointerException
Hi.
We are trying to add a SAP R3 DataSource in Data Federator XI 3.0 SP2.
Test Connection gives us the following message: "The connection was established but there is no table for the given connection parameters", what it seems to be ok according to the SAP doc.
However, when we try to get a list of the Functions or Infosets in the SAP system, an error comes because of a "java.lang.NullPointerException". Checking the application log we get the following:
2010/03/30 12:21:27.059|<=|||0|26537104| |||||||||||||||"[LeSelect.Api.LSStatementImpl] - [Execution Thread 4]Executing query: CALL executeConnectorCommand '/TEST//TEST/user_bla/sources/draft/R3SYS', 'GET_FUNCTION_LIST * * 200'"

We registered the callback program and did all of the steps indicated for the installation, also checked the possible sources of the error according to OSS Note 1278491.
Any idea how to solve this? Thanks.Hello, we have the similar problem: while connecting from Data Federator to SAP ERP we get the following error - "Wrapper /ZTEST/sources/ZTEST reported an exception which is not a WrapperException: java.lang.NullPointerException: null"
It's necessary to install "SAP BusinessObjects Data Federator Infoset, SAP Query and ABAP Functions Connector Prototype"

for connection to SAP ERP.
Are there any ideas? Thanks -
Hello,
I'm trying to run a simple OpenScript script in Eclipse that creates a record (a Supplier in this case) in Oracle E-Business Suite. So I copied the the script file from OpenScript and created it as a Class in Eclipse. Then I created a main class to call the methods within the script class but no matter what method I call (initialize, run or finalize) I'm getting the java.lang.NullPointerException message. The error doesn't seem to be related with any specific line in the script but with the way that I'm calling it.
Should I call the OpenScript class from my main class in a different way? (see my examples below)
BTW, all external .jar files coming with OATS have been added to my project in Eclipse.
1) Here's the main class I created to call the OpenScript method (Eclipse auto-corrected my main class adding a Try and Catch around the method call):
public class Test {
public static void main(String[] args) {
nvscript nvs = new nvscript();
try {
nvs.initialize();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
2) Here's the script from OpenScript (the actual script has more steps but I'm just using the first one for a proof of concept):
import oracle.oats.scripting.modules.basic.api.*;

3) Here's the error messages I'm getting based on the method I call from my main class:

Any help and/or constructive comment will be appreciated it.
Thanks.
Federico.UPDATE
Compiling from command line I found out that the class definition for oracle.oats.scripting.modules.basic.api.IteratingVUserScript is missing. Do you know what .jar file contains this class?
Thanks.

Java.lang.NullPointerException warning beside components on ADF JSP page
java.lang.NullPointerException warning beside components on ADF JSP page problem
Hello
i developed a web application with the help of the Adf technology On jdeveloper 10.1.3.3.0 . Everything is Ok.
But when i use application sometimes on the page i take a java.lang.NullPointerException warn beside the some components like a inputbox or a radio button ..)
i looked the logs but nothing.
How can i solve this problem.
Have you got any idea?Hi,
it's the validator property on inputText components that causes it. not validation or StateValidation or EnableTokenValidation.
Paste your inputText source from the page if you are not sure.

Java.lang.NullPointerException (OC4J 10.1.3.1 & JDeveloper 10.1.3.1)
My project that ran perfectly under JDeveloper 9.0.5.2/OC4J 9.0.2 no loner runs under Jdeveloper 10.1.3.1/OC4J 10.1.3.1.
The failure (java.lang.NullPointerException ) is in the following code snippet:
=================================================
Public String getString(String columnName) throws SQLException {
return getResultSet().getString(columnName);
=================================================
columnName is being passed the same value in both environments.
The JSP snippet that executes the above is:
=================================================
com.app.servlet.SQLDataSource detail =
((com.app.servlet.SQLDataSource)request.getAttribute("AcctList"));
<td width="20%" class="tableRow">
<a class="a4"><%= detail.getString("ACCT")%></a>
</td>
==================================================
AcctList is a text file that contains the following SQL code:
============
select ACCT
, VDESC
from GL
:WhereClause
:OrderByClause
============
:WhereClause & :OrderByClause are set in a calling "Filter" JSP filter page.
All debug statements in my code indicate the the getResultSet is properly executed. Yet when the detail.getString("ACCT") is hit I receive the NullPointerException.
Any clues?
Remember, no code has changed between the 9.0.2 and 10.1.3.1 environments. They both hot the same database with the same JDBC drivers.
TIA,
Ed.Jan,
The NullPointerException is pointed to:
at oracle.jdbc.driver.ScrollableResultSet.findColumn(ScrollableResultSet.java:1308)
at oracle.jdbc.driver.OracleResultSet.getString(OracleResultSet.java:1572)
at oracle.jdbc.SQLDataSource.getString(SQLDataSource.java:388)
at apps.AcctList._jspService(_AcctList.java:66)
The code ( in "_AcctList.java") at line 66 reads:
out.print(detail.getString"ACCT") );
However, digging into my application log file I found that the following error happend at 10:52:46.0 (the above error occured at 10:52.50):
