Null pointer exception in the morning
Hi all,
I have built a custom JSP DYN page application that for the most part works ok. However, I've found on occassion that when I arrive in the morning, the application errors out in our dev and qa portal environments with a null pointer exception type error. The error info in the trace log file is below. I've found that if I redeploy a fresh copy of the application to the dev portal server, it makes the problem go away. In our QA environment, if I restart the portal the problem goes away. In other words, I'm not making any changes to the code to make the problem go away. It's like something has gone awry in the portal.
The trace log file isn't really telling me anything significant. Maybe someone out there has heard of this problem and knows what I'm doing wrong.
Here's the error info:

This runtime error occurs when the application fails to resolve the pernr of the logged in user in the backend. Could you please check if the user has correct assignment in IT0105. If you are using CE, kindly check if the CE settings are properly checked. Also check if the IT0105 is correctly shared across all the CE assignments.
Hope this helps

Your problem is in your ExtendedPage.java file. You can fix this by changing the line

Java Null Pointer Exception while Importing a Table to IS
Hello All,
I am trying to import a table into IS and receiving a JAVA Null Pointer Exception. The table is in a Teradata database and I am able to import other tables belonging to the same schema.I get the Java error only while trying to import this one particular table. The DBA has confirmed that the table belongs to the schema/owner I am using. In any case, it seems more of a application error than a database level error. Can anyone provide any insight? Thank you in advance.hi Keerthi,
thank you.
i tried with below code but still unsuccesfully
+ oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
anyway i'm not able to reach your suggested if statement because execution stops before.
Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
page doesn't give error and saves data.
any suggestion appreciated,
thanx,

Null pointer exception in ISimpleTypeModifiable
Hi
I am trying to add values to dropdownbykey dynamically using this code:
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute("PROCESS");
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
Code is giving null pointer exception in the following line:
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
How to Solve it.Its urgent.
Points will be awarded.Actually the process is the attribute of node within context.
so i changed the code to:
IWDAttributeInfo attributeInfo = wdContext.nodeAuditNode().getNodeInfo().getAttribute("PROCESS") ;
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
The second point is: we can't modify the data type of mapped attribute in view controller.
So for that, we have to write that code in component controller. -
Null Pointer exception in Webshop
Hi,
We are facing a problem of null pointer exception in the webshop when opening the product details (only in case of handful of products and not for other products) from the hyperlink of the product in the basket.
The product itself appears with short description as soon as we type the product ID in the basket along with price. Still, only for certain products, we always get the null pointer exception when opening the hyperlink of the product details.
The logs of initial replication as well as delta replications later on do not indicate any errors during replication.
These few products are no different from the rest that are OK in the webshop. The details in the product master is also no different. I have tried delta replication multiple times and all of them have been successful. The trace at Unix level also did not help much.
Can somebody help?

GetUserRoles in viewobject throws null pointer exception
Hello,
I've set up security for our jsf-adf-bc4j application.
I now want to get the user role in our viewobject.
I use the following code :
SessionImpl session = (SessionImpl) this.getDBTransaction().getSession();
String[] roles = session.getUserRoles();
for (String role : roles){
System.out.println(role);
This throws a null pointer exception at the"System.out.println(role);" line .
The user has a role (I can read the role in the viewcontroller project)
In the view object i can also get the session.getUserPrincipalName(). This works fine.
Can anybody help me with this problem ?You define a local ArrayList here:public MonthlySchedule()
ArrayList<Request> monthlyschedule= new ArrayList<Request>() ;
}Just instanciate the instance variable. -

If a EJB (Remote) has a method that returns an ArrayList, and one of the entries of the ArrayList is null, we get a NullPointerException, when clonnning the ArrayList .
This looks same as the one posted in relation EJB-Remote returning HashMap has null values. -

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)

Null pointer exceptions in CallableStatement
Hi,
Has anyone seen this problem before? I have an app that needs to invoke a stored proc on a SQLServer 2000 database, using the MS SQLServer 2000 JDBC drivers.
We were doing this via CallableStatement classes, but unless we specify implicit transactions in the stored proc itself, this fails with a null pointer exception at the point at which we try to retrieve the resultset from the CallableStatement, after calling CallableStatement.execute.
If I re-factor the code to use just plain Statement classes, and an SQL string that executes the stored proc (as if I were typing the SQL in query analyzer) then it works perfectly without needing to have implicit transactions turned on in the proc?
Any ideas?
Many thanks....Ok, broadly it's as follows:
CallableStatement stmt = conn.prepareCall("{Call MyStoredProc(?,?)}");
stmt.setString(1, null);
stmt.setString(2, "Test Value");
stmt.execute;
ResultSet rs = stmt.getResultSet();
if (rs.next()) {
System.out.println("RS1=" + rs.getString(1));
}That falls over at rs.next() unless the underlying stored proc has implicit transactions turned on. The stored proc can be executed through SQL Query Analyzer with the values used in my code successfully, also by just using 'normal' Statement classes and calling stmt.execute(sql) where sql is the string containg the sql I would use in query analyzer. -
Af:tree Null Pointer Exception using af:switcher
Hi,
I've implemented a Tree (based on 3 linked SQL Query View Objects). The linked View Objects run ok in the Application Module tester...
I wanted to customize the different levels of the tree so implemented a Switcher component on the Tree as follows (note I've limited the Tree to 2 levels):
<af:tree value="#{bindings.listToDoAppsVO1.treeModel}" summary="ToDo List Tree" var="node"
id="pt_t8" contentDelivery="lazy"
initiallyExpanded="true"
styleClass="AFStretchWidth" inlineStyle="height:inherit;">
<f:facet name="nodeStamp">
<af:switcher facetName="#{node.hierType.structureDefName}" id="todo_switcher">
<!-- render the Application Node -->
<f:facet name="app_model.listToDoAppsVO">
<!-- display the Application as the node name -->
<af:outputText value="#{node.Appname}" id="ot_app">
</af:outputText>
</f:facet>
<f:facet name="app_model.listToDoTypesVO">
<!-- Create the node definition for the Report Type -->
<af:commandImageLink id="pt_ot16"
text="#{node.Viewtype}"
icon="/pics/folder-icon.png"
action="callRouter"
actionListener="#{backingBeanScope.cognition3coltempBacking.toDoViewGoActionListener}"
/>
</f:facet>
</af:switcher>
</f:facet>
</af:tree>However, when the page is run the Tree displays correctly initially, but as soon as a link is pressed I get a Null Pointer exception with the following Stack Trace info (top 30 or so lines):

Any ideas please? I'm using JDeveloper 11.1.2.1.0 incidentally...
Thanks.Hi Frank,
Thanks for your reply. The Partial Submit worked up to a point - the expected navigation to the new view now works when the link is initially pressed. However, if the link is tried again the Null Pointer Exception occurs again.
By the way, the Tree is on a Page Template, where there is another Tree that utilises an af:switcher - and the command link from this tree now fails with the same NPE error. I notice there are warnings for both trees in the Page Template View such that 'Reference "node.hierType" not found'. Not sure how relevant this is given that the Trees both display correctly initially.
The Stack Trace is as follows (can't post the whole thing as it exceeds the 30000 char limit):
<UIXInclude> <_warnUnpoppedContextChanges> ADF_FACES-10021:During the processing of the include component, the context change found did not match the current component. Expected oracle.adf.view.rich.component.fragment.UIXInclude$IncludeContextChange, but got UIXCollection.CollectionComponentChange[Component class: oracle.adf.view.rich.component.rich.data.RichTree, component ID: pt_t8].

Using Back button causes Null Pointer exception
Hi,
I have done some customization by extending the seeded Controller on a Page.I have altered the View query and executed it again dynamically as its not a static query.
There is a functionality called compare which directs the users to a page from the page I have customised the controller.
If the user uses the back button to return to the previous page it is giving a Null Pointer exception.
Also refresh button causes a similar Null Pointer exception on the customised controller page.
can anybody throw some light?
Also is there a way to disable the back and refresh button on the page?Is the control entering the back button code in process request in your CO? Have you confirmed this by putting some debug comments?It many be that this error might being from the code where you have handled back button.
Put debugging comments and check.
