JTextArea, getText, and Null pointer exception
Hi, I am having trouble figuring out why i get a null pointer exception when i call
ta = theGUI.AbName_TA;
ta.getText();does anyone have any ideas as to what the problem is?
(NOTE: i am somewhat new to java, and am DEFINITELY new to swing. so, if there is a better way to go about the stuff that i'm trying to accomplish, PLEASE feel free to offer suggestions.)
Thanks, Kim

I changed my "actionPerformed" function a bit.
Thanks for your comments - I hadn't realized some mistakes I had made while trying to fix my code.
I'm still getting a null pointer exception, though.
Also, in the main function of GUI_CreateAntibody, I call init for GUI_CreateAntibody. Within THIS init function I call init for GUI_CreateAntibody_Sketcher. I don't understand what is wrong with this (except that I suppose I should be using constructors as opposed to init functions.)
Thanks,
Kim

Returning vector and null pointer exception
Hi, I'm writing a mailing program which so far is working fine, but I have now run into a problem which is completely throwing me. My mailer needs to be able to load multiple attachments - and also to be able to deal with an HTML text which contains multiple images. In each case, what I'm trying to do is to put the attachments and the images into separate vectors and process them through an iterator. The logic, at least, I hope is correct.
I can get my code to compile but it keeps throwing a null pointer exception a runtime. Somehow, I just can't get it to pass the vector from one part of the code to another.
Can anyone help me? I've tried various things, none of which seem to work. My code, as it stands, is posted in a skeletal form below.
Thanks for any ideas:
public class MailSender
// declare various variables, including:
Vector embeddedImages;
String HTMLString;
public MailSender()
setup();
private void setup()
//this part of the program sets up the various parts of the mail (to, from, body etc)
HTMLString = "blah blah blah"; //sample HTMLString
Vector embeddedImages = null; //is this correct?
if (HTMLString.length() > 0)
processHTMLString(HTMLString);
private String procesHTMLString(String htmlText)
Vector embeddedImages = new Vector(); // I construct my vector here, is this correct?
//Here I process the HTML string to extract the images
//get the file path of the image and pass it to the vector
addToVector(imageFile);
return HTMLString;
public Vector addToVector(String imageFile)
embeddedImages.add(imageFile);
return embeddedImages;
private void send()
//this part does the sending of the mail
//at some part in this method I need to get at the contents of the vector:
//but this part isn't working, I keep getting a null pointer exception
Iterator singleImage = embeddedImages.iterator();
while (singleImage.hasNext())
public static void main(String[] args)
MailSender ms = new MailSender();
ms.send();
System.out.println("MailSender is done ");
}>>>>while they don't have a clue on how the language and/or programming in general works.
Thank you, salpeter, for your esteemed estimation of my programming competence.
>>>What I'm wondering is: how come people always start building applications... blah blah
The reason being, is that it happens to be my job.
OK, I'm perhaps slower than most and there are things I don't yet understand but I get paid probably about a tenth of what you do (and maybe even less). I regard it as a kind of apprenticeship which, after a past life having spent twenty years packing crates in a warehouse, is worth the sacrifice. Six months ago I'd never written a line of code in my life and everything I've learned since has been from books, the good people in these forums, and a lot of patient trial and error. It's hard work, but I'll get there.
I say this, only as encouragement to anyone else who is trying to learn java and hasn't had the benefit of IT training at school and a four year computing course at university paid for by the parents, and for whom the prohibitive cost (in both time and money) of most java courses would never allow them to get on this ladder.
Excuse my somewhat acerbic posting, but comments such as yours tend to provoke...
Thank you EverNewJoy for explaining this to me. I haven't had time yet to try it out, but at least the concept now is clear to me. -
Drop down menu and null pointer exception
I am trying to build a drop down menu that gives you options on sorting a list (eg. it sorts on the Title) . The drop down must show which sort option has been selected after the sort occurs.
I keep getting a "java.lang.NullPointerException". I realize this error arises from not assigning a variable to a specific object in java. I'm a .net developer who got thrown into customixing a java application and I just don't see the error. The error message didn't say on which line this occured but it is in the posted code.
It worked for a while and now i gives me this error.
Can someone help me please!?!?

</form> Thanks,
LuisThis is not JSF ..
Anyway, it looks like that the following code returns nullsession.getAttribute( "theUid" )and invoking the equals() on it thus causes a NullPointerException.
So check if this attribute really exists in the session and add a nullpointer check to the code. For example:if (session.getAttribute("theUid") != null && session.getAttribute("theUid").equals("blah")) { } -
Can you please look at this stack trace to see if you can identify a reason why this error happens when I leave a page open in my ADF application for 3 minutes or longer?

I do not get this error when I run the application on the Weblogic standalone server. I do not get this error when I run the application on my integrated weblogic server, unless I run it is debug mode. I do get it on my integrated weblogic server if I run in debug mode.
Can you please give me an idea of where I can look for settings on the other weblogic servers where this is happening to see if I can chase this down? I am not a weblogic server admin by any means, but I have looked at the Debug tab for the server to see if I can see anything enabled. Unfortunately, I may not be looking in the right place to know if there is some kind of debug setting enabled.
Any assistance would be greatly appreciated! This is happening to our users on our production server as well.
Thank you! -

Is there a reason why this is and how do I get by it.
ii. Can I just add the field directly within the MDS>file/user.xml? Would there be an issue with changing an existing attribute metadata using the user.xml?Pradeep thank you for your response. it was helpful. However, I also found the responses to both my questions.
i. The null pointer exception was due to using a complex query I was using in the LOV query. I tried a simple query and that worked fine.
ii. For modifying the user defined attributes one can consult the following forum post:
OIM 11g - Change UDF Field Type form String to LOV
Thanks -
Null pointer exception and servlet
I cant figure out why i am getting a null pointer exception. this works if i keep my form output in the same class as my driving servlet. All i did was break off the html display to a new form and i get a null pointer exception.
this is just an excerpt. no reason to post the whole form.

}anyway to write the system.err to an html screen with
a servlet?Why would you ask that? Surely you should have asked "Any way to write a stack trace to an HTML screen from a servlet?"
And in fact there is. I am sure you have not yet looked up the Exception class and the versions of its printStackTrace() method. But when you do, you will see that there are printStackTrace(PrintStream) and printStackTrace(PrintWriter). And you know how to write HTML (or text in general) to the servlet response so that it shows up in the client's browser, right? I will let you figure out how to put those things together. -
Null Pointer Exception and Illegal Arguement when ran with Wireless Toolkit
The following code throws a null pointer exception after it tried to initialize the textBox. I am not sure if there is something I am not importing, or if it's just because I'm sick and my head is cloudy. :-}.
I am using Wireless Toolkit 2.2 and Java 5.0
Anyhelp would be appreicated. Thank You.

tbHelp = new TextBox("HeLp", "You can press the back button", 25, 0);
This line declares a maximum textbox size of 25 but in reality he is declaring a textbox of size 29.
Thats why it is throwing the illegal argument.
happy coding :) -
JAX-WS Client throws NULL Pointer Exception in NW 7.1 SP3 and higher
All,
My JAX-WS client is throwing an exception when attempting to create a client to connect to the calculation service. The exception is coming out of the core JAX-WS classes that are part of NetWeaver. (see exception below)
Caused by: java.lang.NullPointerException
at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatchContextExistingPort(SAPServiceDelegate.java:440)
at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatchContext(SAPServiceDelegate.java:475)
at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatch(SAPServiceDelegate.java:492)
at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatch(SAPServiceDelegate.java:484)
at javax.xml.ws.Service.createDispatch(Service.java:166)
I have done some research and it appears that as of NetWeaver 7.1 SP3 SAP stopped using the SUN JAX-WS runtime and implemented their own SAP JAX-WS runtime. I also took the time to decompile the jar file that contained the SAPServiceDelegate class which is throwing the null pointer exception. (see method from SAPServiceDelegate below)
private ClientConfigurationContext createDispatchContextExistingPort(QName portName, JAXBContext jaxbContext)
BindingData bindingData;
InterfaceMapping interfaceMap;
InterfaceData interfaceData;
bindingData = clientServiceCtx.getServiceData().getBindingData(portName);
if(bindingData == null)
throw new WebServiceException((new StringBuilder()).append("Binding data '").append(portName.toString()).append("' is missing!").toString());
QName bindingQName = new QName(bindingData.getBindingNamespace(), bindingData.getBindingName());
interfaceMap = getInterfaceMapping(bindingQName, clientServiceCtx);
interfaceData = getInterfaceData(interfaceMap.getPortType());
ClientConfigurationContext result = DynamicServiceImpl.createClientConfiguration(bindingData, interfaceData, interfaceMap, null, jaxbContext, getClass().getClassLoader(), clientServiceCtx, new SOAPTransportBinding(), false, 1);
return result;
WebserviceClientException x;
x;
throw new WebServiceException(x);
The exception is being throw on the line where the interfaceMap.getPortType() is being passed into the getInterfaceData method. I checked the getInterfaceMapping method which returns the interfaceMap (line above the line throwing the exception). This method returns NULL if an interface cannot be found. (see getInterfaceMapping method below)
public static InterfaceMapping getInterfaceMapping(QName bindingQName, ClientServiceContext context)
InterfaceMapping interfaces[] = context.getMappingRules().getInterface();
for(int i = 0; i < interfaces.length; i++)
if(bindingQName.equals(interfaces<i>.getBindingQName()))
return interfaces<i>;
return null;
What appears to be happening is that the getInterfaceMapping method returns NULL then the next line in the createDispatchContextExistingPort method attempts to call the getPortType() method on a NULL and throws the Null Pointer Exception.
I have included the code we use to create a client below. It works fine on all the platforms we support with the exception of NetWeaver 7.1 SP3 and higher (I already checked SP5 as well)
//Create URL for service WSDL
URL serviceURL = new URL(null, wsEndpointWSDL);
//create service qname
QName serviceQName = new QName(targetNamespace, "WSService");
//create port qname
QName portQName = new QName(targetNamespace, "WSPortName");
//create service
Service service = Service.create(serviceURL, serviceQName);
//create dispatch on port
serviceDispatch = service.createDispatch(portQName, Source.class, Service.Mode.PAYLOAD);
What do I need to change in order to create a JAX-WS dispatch client on top of the SAP JAX-WS runtime?Hi Guys,
I am getting the same error. Any resolution or updates on this.
Were you able to fix this error.
Thanks,

9.3.3 Upgrade, null pointer exception when accessing business rules and mac
Hello,
We upgraded from 9.3.1 to 9.3.3. In the Essbase Administration Services Console, when I attempt to access business rules or macros from a client PC, we get a null pointer exception. The message does not tell us much, but I cannot find more.
I can access business rules and macros using EAS Console from the server. Do I have a bad installation, or have I missed a step?
Thank you,Hi,
You might have to re-organize your application module hierarchy to place your common code.
If your intension is to auto populate the primary key for your Entity Objects., I would suggest below common practice.
1). Create a Base Entity Impl class for your project that extends oracle.jbo.server.EntityImpl
2). Code your getDbSequence() method inside this base entity impl class
3). Make sure that all your Entity Objects extend your base entity impl class
4). Use EL expression to call this method for auto-generating primary key attribute of your Entity Object.
e.g., adf.object.getDbSequence("sequenceName")

PLease Help me !!
I need this urgently.can you explain what your program tries to do... and
at where it went wrong..Sir,
We are trying to make an project where we can make a person register in our data base & after which he/she can search for other user.
The logged in user can modify his/her own data but can view other ppl's data.
We are in a phase of registering the user & that's where we are stuck. The problem is that after the login screen when we hit register (OK- button) the data are not getting entered in the data base.
Can u please help me??
I am using "jdk1.3' - studnet's edition.
I am waiting for your reply.
Thanks in advance & yr interest. -
Null pointer exception with inner class
Hi everyone,
I've written an applet that is an animation of a wheel turning. The animation is drawn on a customised JPanel which is an inner class called animateArea. The main class is called Rotary. It runs fine when I run it from JBuilder in the Applet Viewer. However when I try to open the html in internet explorer it gives me null pointer exceptions like the following:
java.lang.NullPointerException

Do inner classes have to be compiled seperately or anything?
Thanks a million for you time,
CurtinRI think that I am using the Java plugin ( Its a computer in college so I'm not certain but I just tried running an applet from the Swing tutorial and it worked)
Its an image of a rotating wheel and in each sector of the wheel is the name of a person - when you click on the sector it goes red and the email window should come up (that doesn't work yet though). The stop and play buttons stop or start the animation. It is started by default.
This is the code for the applet:

REG : Null Pointer Exception for RFC values
Hi All,
I am facing peculiar erro in code.I need to check the null entries in SAP server then it should be replaced by space and if not null then should be replaced by the value in backend.But it is throwing null pointer exception
I am using equalsignore case(null) and trim for space.
I am not getting why its is throwing null pointer exception.Kindly advise
Regards,
AnupamaHi
Use
String f = null ;
if(f!==null)
Wdcomponent.getMessageManager.ReportException ("this will cause null pointer exception "+ f.length());
Better to give it any Constant like
priveate static final String NULL_CHECK = "DEL_VAL12";
rather than space ,at the time of chceking see if it has DEL_VAL12 if true then put the actual data else let it be there.
Best Regards

Null Pointer exception returned when object is not null!
I've isolated the problem and cut down the code to the minimum. Why do I get a null pointer exception when the start method is called, when the object objJTextField is not null at this point???? I'm really stuck here, HELP!
(two small java files, save as BasePage.java and ExtendedPage.java and then run ExtendedPage)
first file

ExtendedPage objEP = new ExtendedPage();
objEP.show();Hello ppaulf,
Your problem is in your ExtendedPage.java file. You can fix this by changing the line
private JTextField objJTextField = null;to:
private JTextField objJTextField = new JTextField();This creates a proper instance.
Good luck,

JRC (upg. to CR4E) - Report w Subreport - Oracle DB - Null Pointer Excepti
Hi
We have a Crystal Designer/Developer Version 11.5.10.1263. We develop reports using this.
Most of the reports have SQL Command mode design with JNDI/JDBC connection. It gets deployed with our Web application. And during runtime, when users access these reports from our web application, we typically use Java Reporting Component with Crystal Report Viewer SDK to open and display the report to the user.
Besides other issues, current problem I am having is:
I have a sub-report in my report. I am connecting to Oracle database. If this sub-report does not return any rows, I was getting a Null Pointer Exception. This seems to be a known bug. This happened to us when we had just the above mentioned components.
We recently upgraded just the JAR libraries to the ones packaged in CR4E (Crystal Reports For Eclipse) - initially to get more exporting capability.This upgrade gets us past the Null Pointer Exception issue.
Now, I am getting an error like "Unexpected database connector error". Please see the exception stack trace below if needed. Since we are a product and this display is specific to one out of about 100 different clients; with all the time we spent on making this report stuff work against this oracle DB client, we had finally ended up creating the display in JSP into our general product just for one of about 100 clients. Client must be the Lucky one...As a developer, I felt really frustrated.
One note:- SQL Server DB works perfect.
Other thing - Do we need to change any API calls after upgrading the JARS from standard JRC/Viewer to CR4E package?

In my case, I can get my report to work with a single subreport. When I put multiple subreports, I get the same error as you are currently getting.
Check if your report has any special section formatting (conditional suppression etc). Try to remove those to see if it helps at all. -
