Kodo.jdbc.MappingFactory Null Pointer Exception
Hi I got a problem with the kodoworkbench.
I'm trying to save the mapping information into the .jdo file.
So I set
kodo.jdbc.MappingFactory=metadata
in my kodo.properties.
When I try to save the mapping information I get the following exceptions:
Seems that a string value is missing anywhere but i don't now where ?
Thanks

Hi,
No, if I use the file factory I do not get the errors.
Here is the mapping info from an exported .mapping file.
The exception raises when I change the tablename to STUDENT and then I try
to save it.
I stopped working with the workbench and started editing the .mapping by
hand, because I get several NullPointerException without helpful exception
messages.
Thanks

Katze-
If you use the "file" mapping factory, do you get the same error? Also,
can you provide any details about the mappings you are trying to create
(e.g., what is the inheritance strategy, etc)?

Null pointer exception occured in jdbc application
Hi all,
I am trying to test a sample application in JDBC. While running it in eclipse IDE I am getting the below result.
CourseId:25 CourseName: SQL
CourseId:54 CourseName: XML
CourseId:61 CourseName: HTML
java.lang.NullPointerException
The code i am using is
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}catch(ClassNotFoundException e)
System.out.println("Expected class not found");
return;
try{
Connection con=DriverManager.getConnection("jdbc:odbc:star"," "," ");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("select * from ex1");
while(rs.next())
System.out.println("CourseId:"+rs.getString(1)+" ourseName: "+rs.getString(2));
rs.close();
stmt.close();
con.close();
}catch(Exception e){
System.out.print(e);
Please let me know what i am doing wrong. What should i do to eliminate that null pointer exception in the result.Hi Newbee...
I jsut ran ur program on my system..
and it works fine on my system. No exception at
all...
..AmanWhich is why I asked about the data. If this were my program, I would look to see if the data is what I am expecting (no nulls, proper strings, etc).
Nice of you to actually run Newbee's program though... -

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. -
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. -

MasoodWhat is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

I am testing BOE 4.0 with a simple jsp based on the samples. The code is what I used to test BOE xi 3.1. But I ran into some report display inconsistencies with 3.1 so I am trying 4.0. The code below works in 3.1 But in 4.0, I get the report viewer screen coming up but get a null pointer exception coming to the screen.

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. -
Null pointer exception to database
I can' figure out why it keeps giving me a null pointer exception. I have a database in which I am supposed to search through it based on user input given on a servlet page. Here is the code. Also if anyone could help me on how to execute queries based on an exact search, all search, or any search, that would be great. thanks

}It's easy to see why:
conn.createStatement();This method returns a Statement, but you don't assign that value to anything. Your data member stmt is set to null and you never change the value.
You've got another problem, though. Once you close that connection you can't talk to the database anymore.
You either have to create a connection inside the doGet and close both as soon as you're done with it OR figure out how to use a connection pool. Tomcat can do it for you. Maybe it's worth a read:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
You're not working with the ResultSet properly, either. Do something like this:
rs = stmt.executeQuery("SELECT protocolID,serverID,pageName FROM pages WHERE pageContent LIKE %ucf%");
while (rs.next())
out.println(rs.getString(1) + rs.getString(2) + rs.getString(3));
}I'm not sure how well that LIKE clause is going to work out.
I'd look at the JDBC tutorial to the left, too. It doesn't look like you've done SQL and JDBC before. - MOD -
Null pointer exception without any reason
Can anybody tell me why the following portin of code is throwing null pointer exception
Connection con=null;
ResultSet rs;
Statement stmt=null;
try{
//----------------- Driver -------------------
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//----------------- URL WITHOUT DSN ----------------------------
String conString = "jdbc:odbc:DRIVER={MicroSoft Access Driver (*.mdb)};" +
"DBQ=./data/RMS.mdb";
con = DriverManager.getConnection(conString,"","");
stmt = con.createStatement();
String sql="SELECT * FROM Employee";
stmt.executeQuery(sql);
rs.next();
catch(ClassNotFoundException cnfe){ System.out.println("Driver Not Found !!!"); }
catch(SQLException sqle){
System.out.println("DSN Not Found !!!"); }Thanks a lot brother, how could I do such mistake!!
One more thing, can you tell me how to delete the trace of PK auto-number from MsAccess DB.I mean, if I delete all the data from the table and insert again, yet it does not start from Pk id- 1, auto-number starts from after the previously deleted data.How can I make it start from -" 1 " , if there is no data in the table.
THANKS in advance.

Null Pointer Exception on stmt = conn.prepareStatement( query );
I configured the Tomcat 5.0.27 for using the connection pool feature and connecting to the Oracle. I am testing if I did the configuration correctly. Therefore, I try to retrieve some data from a table. I got the
'Null Pointer Exception" when executing the
stmt = conn.prepareStatement( query );I am not sure where the problem is from.
1. configuration is not done properly?
2. some bugs in my program?
I need your help to diagnose the problem. The messages in the Tomcat log are shown below my program coce.

Oracle native API for AQ - Null pointer exception
Hi
I am trying to enqueue a message to AQ adapter through the java native api. But i am getting a null pointer exception.
import java.sql.*;
import oracle.AQ.*;
Connection db_conn;
AQSession aq_sess = null;
AQQueueTable q_table = null;
AQQueue queue = null;
AQMessage message ;

aq_sess = AQDriverManager.createAQSession(db_conn);
System.out.println("Successfully created AQSession ");
q_table = aq_sess.getQueueTable ("soabrm", "AQ_Test");
queue = aq_sess.getQueue ("soabrm", "AQ_Queue_Test");
message = queue.createMessage();
b_array = test_data.getBytes();
AQRawPayload raw_payload = message.getRawPayload();
AQEnqueueOption enq_option = new AQEnqueueOption();

message.setRawPayload(raw_payload);
queue.enqueue(enq_option, message);
db_conn.commit();

System.out.println("Exception "+ex.getMessage());
Error : Exception null
Please let me know if I missed something.
Thanks in advance!!!!!hi,
I had found the issue. The queue takes object type messages where as I was trying with Raw messages.
Instead of AQRawPayload raw_payload = message.getRawPayload();
I need to use
AQObjectPayload raw_payload = message.getObjectPayload()
and pass object as input to the queue. -

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:

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

}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. -

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.
