JFileChooser throws NullPointerException when in a non-traversable Dir
Hi all
I think I found a bug of JFileChooser. Unless one of you knows the issue and the corresponding workaround.
It occurs when one extends JFileChooser and overrides isTraversable() to dissalow the navigation to specific
directories. When the user then uses the JComboBox of the JFilechooser dialog to navigate to a non-allowed
directory and from there tries to again select a not allowed directory, the following Exception gets thrown
within the JFileChooser.showDialog method.
To reproduce this try:
import java.io.File;
import javax.swing.JFileChooser;
public class yxJFileChooser
extends JFileChooser
public boolean isTraversable(File _f)
if (_f == null) return false;
else if (!_f.isDirectory()) return false;
String fileToCheck = _f.getAbsolutePath().toLowerCase();
if (fileToCheck.startsWith("c:\\windows")) return true;
else return false;
}the try:
yxJFileChooser fc = new yxJFileChooser();
int ret = fc.showDialog(null,"try the combo twice. Choose both times a non traversable dir");Once you have chosen for the second time a non-valid directory (using the combo) you will get a NullPointerException:
Is this indeed a Java VM bug or am I doing something wrong?
My operating system is Windows XP service pack 2 and the java version I am running this with is:
java version "1.6.0-rc"
Java(TM) SE Runtime Environment (build 1.6.0-rc-b102)
Java HotSpot(TM) Client VM (build 1.6.0-rc-b102, mixed mode)
Here the Exception:

Weblogic throws NullPointerException when using ServiceControl.setTimeout
We are invoking a SOAP service via a com.bea.control.ServiceControl that was generated from a WSDL (right click WSDL, Generate Service Control) using Weblogic 8.1.6.
SOAP service execution is successful using an http and https endpoint. However, when setting a timeout via ServiceControl.setTimeout(int millisecods) method, the Weblogic API is throwing a NullPointerException when using an https endpoint. When using an http endpoint with the setTimeout method execution is successful.

JFileChooser throws NullPointerException
Dear all,
Please check out the following code:
JFileChooser addItemChooser = new JFileChooser();
addItemChooser.setMultiSelectionEnabled(true);
int returnVal = addItemChooser.showDialog( SAP_Functions.this, "Add" );
if (returnVal == JFileChooser.APPROVE_OPTION)
File selectedFiles[] = listFileChooser.getSelectedFiles();
When running the program i get the FileChooser but when i approve the selection the compiler gives me a NullPointerException message, what are the possible reasons for it?
Thanks for your help.
Kareem NaouriLooking at your code, I think what you mean to do is
File[] selectedFiles = addItemChooser.getSelectedFiles();
That is call getSelectedFiles() on the JFileChooser object that you have declared and instantiated within your code. -
LOV throws NullPointerException when there are no rows to display
Hi,
I have cascading LOVs in my application. I have 3 of them. I select values for the first 2 LOVs, and then I click on the 3rd LOV. The query for the third LOV returns no records from the database and so, a NullPointerException is thrown.
When there are no rows to display in the LOV, I want the LOV to still pop up with a message saying "No rows to display".
Is there a way I can achieve this functionality using the existing features?
I am using JDev 11.1.1.3.0
Thanks

Workshop throws NullPointerException when starts
Hi, I recently installed WL Portal 10.1 on a Windows XP SP2 machine and I'm working on migrating a 8.1.5 app into 10.1.
Everything seems working fine, until all of the sudden, the next time I open the WL workshop, I get a nasty error:
An unexpected error has occurred in Workshop. This error may be due to a bug in the program...
from the .log file:

Any help is appreciated! the only way I can get around this error is by deleting the workspace and creating a new one, but after a few days, it happens again :(
Thanks!
Javier.Vimala, I made the change yesterday (after re-creating the workspace) and was working fine all day. This morning I opened the Workshop for the first time, and the error is back :-(
Any other ideas?

Edited by: Saravana Parthiban Palaniswamy on Feb 4, 2009 1:26 PMHi,
If u goes to room directory in collaboration, there is a tab called Restricted Rooms. End of the room name there is context menu if u click that, it will show the menu there you can see the option called Request Membership. If you click that, corresponding room owner will receive the mail if he/she enabled the mail properties.
If the answer helps your Question, provide the points.

IsTraversable making files invisible, rather than non-traversable
I have some files stored in a folder (some kind of "compound" file) so when the user opens the folder it acts like a file. At the moment I am drawing its own little icon and stuff, everything works fine except the user can "double click" on the file and instead of opening it, they will go into it and see all the guts inside. I found the isTraversable method of the FileView object and that does half the job (other half would be to support double - click opening) However, when i try to use it anything I set as non traversable becomes invisible. I suppose its doing its job (I cannot traverse the file that isnt there) but i would like to be able to choose this file.
public Boolean isTraversable(File f)
Boolean ret = super.isTraversable(f);
if (QuantitationFileChooser.isQuantitationFile(f, false))
ret= new Boolean(false);
return ret;
}Am i missing the point of this function or something? It seem pretty simple, i have no idea what i am doing wrong! The documentation says its exactly what i want:
"public Boolean isTraversable(File f) Whether the directory is traversable or not. This might be useful, for example, if you want a directory to represent a compound document and don't want the user to descend into it. "

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 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 help me , thank you
Edited by: Rocky.c.Xu on 2013-3-1 上午2:52Solved it on my own.
The sso from Java->ABAP was OK
I reconfigured the sso from ABAP->JAVA by creating new ABAP certificate and import it to the J2EE.

CreateEntityManagerFactory throws NullPointerException for ejb3 jse client
This question has been posted to the Toplink/jpa forum without any reply.
Dear experts!
I am trying to create a java standard edition client, to test outside the weblogic server, my ejb 3 entities, declared as shown in the following persistence.xml.
The java code follows also. I have read about some relevant bugs in eclipselink back in 2006, or 7 or 8 and mostly unanswered threads :
CreateEntityManagerFactory null pointer exception and
Returned null to createEntityManagerFactory about tomcat and oc4j.
Persistence.createEntityManagerFactory() throw NullPointerException in oc4j
I am using JDeveloper 11g Studio Edition Version 11.1.1.3.0, Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660.
Any helping hand available?
Thank you very much in advance!

Process exited with exit code 1.Thank you for your reply!
The client now works correctly. It seems that the line
em = emf.createEntityManager(emProps);//
throws an exception when no argument is given for em = emf.createEntityManager();// emProps missing!
There was also a warning in jdev editor, about the line you mentioned:
<property name="eclipselink.target-server" value="WebLogic 10"/>
Carry on with your good work!

Reset 'Administrator' when there is None?
How can I reset 'Administrator' when there is None?
Up to now I was only mildly disappointed at the process of rebuilding mom's aging iMac. Basically, she needs to throw it away, sparing any subsuquent user the hassles I've endured 24/7 for the past 8 days or so... So, now I have a great, and utterly simple question which every single advanced user should know how to resolve. "Jean" -the main and only named user, is not an Administrator, and evidently it wants some other password to enter the space that would enable us to go any further.
I can firewire the drive, doctor it from my REAL Macintosh, and I can blank it out for a third time and start over, but eventually the motherboard is going to catch fire, that's a certainty. This brings into question the entire validity of rerstoring "Permissions"alltogether.This may help:
Restore admin user status.
If your admin user loses admin status for whatever reason (and it has happened to a few people), and you do not have a second admin account, then try the following:
Boot into single-user mode. At the prompt enter:
mount -uw /
nicl -raw /var/db/netinfo/local.nidb -merge /groups/admin users your-username-here
Press RETURN after each command. To restart in OS X enter:
reboot
I recommend you write down these commands in a monospaced font. Be sure to carefully note where there are spaces in the command line.
