[Tomcat] Incompatible object argument for function call

Hello,
I've got a jsp which use a DOM parser to read XML. This jsp works good on my station :
Tomcat 4.1.24
JDK 1.3.1_07
Windows XP
I put my webapp on another station :
Tomcat 4.1.24 (the same)
JDK 1.3.1_12
Windows NT
but there, my jsp return an error :
java.lang.VerifyError: (class: org/apache/jsp/doFncaBourse_jsp, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Incompatible object argument for function call

Thanks et good afternoon and sorry for my english.

Is it enough to write
set JAVA_OPT= "-noverify"
before
set EXECJAVA=%RUNJAVA%
set MAINCLASS=org.apache.catalina.startup.Bootstrap
set ACTION=start
set SECURITY_POLICY_FILE=
set DEBUG_OPTS=

Java.lang.VerifyError - Incompatible object argument for function call

Hi all,
I'm developing a JSP application (powered by Tomcat 4.0.1 in JDK 1.3, in Eclipse 3.3). Among other stuff I have 3 classes interacting with an Oracle database, covering 3 use cases - renaming, adding and deleting an database object. The renaming class simply updates the database with a String variable it receives from the request object, whereas the other two classes perform some calculations with the request data and update the database accordingly.
When the adding or deleting classes are executed, by performing the appropriate actions through the web application, Tomcat throws the following:
java.lang.VerifyError: (class: action/GliederungNewAction, method: insertNewNode signature: (Loracle/jdbc/driver/OracleConnection;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V) Incompatible object argument for function call

...The renaming works fine though. I have checked mailing lists and forums as well as contacted the company's java support but everything I have tried out so far, from exchanging the xerces.jar files found in JDOM and Tomcat to rebuidling the project didn't help.
I just can't explain to myself why this error occurs and I don't see how some additional Java code in the other 2 classes could cause it?
I realize that the Tomcat and JDK versions I'm using are totally out of date, but that's company's current standard and I can't really change that.
Here's the source code. I moved parts of the business logic from Java to Oracle recently but I left the SQL statements that the Oracle stored procedures are executing if it helps someone.

After further googling I figured out what was causing the problem: in eclipse I was referring to external libraries located in eclipse/plugins directory, whereas Tomcat was referring to the same libraries (possibly older versions) in it's common/lib directory.

Hello Arnold,
Can you provide us the exact information about the implementation version and Ant-version of the cesession.jar file that you are using.
This could be observed by opening the jar file using winrar or winzip, then go to the MANIFEST.MF file present inside META-INF folder.
Once you will open the MANIFEST.MF file, please let us know the first seven lines present inside the same fle.
Thanks,

Incompatible object argument for function call exception

I am hoping someone has seen this issue before.
Running CF 7.0.1.116466 with JRun 4.
I have a 3rd party search engine application running on a
separate server. I interface with the engine via their Java API. I
am able to use the search engine when executing using a home grown
Java application. It also worked with CF 6. However, when I try to
implement the same cold in CF, it fails with the exception attached
below. I am able to successfully create the objects. The error
occurs when the objects attempt to connect with the engine.
I have also attached the code that is causing the errors.
"seObj" creates an interface with the search engine. It is
constructed with the server address as a parameter. It does not
attempt to contact the engine when it is first constructed.
"dsObj" allows access to specific content in the engine. This
is where the connection to the engine is attempted and the error
occurs.
Any assistance would be greatly appreciated.

Hi, Thanks.
But the problem is still there.
If I put
public class SimpleThread extends Thread
No problem, but if I put
public class SimpleThread implements Runnable
I got java.lang.VerifyError: (class: TestNotify, method: main signature: ([Ljava/lang/String;)V) Incompatible object argument for function call

Please refer to the following code:
public class SimpleThread implements Runnable {

Incompatible object argument for function call

What is the prototype of the function you're calling?
void Norm(uint8_t *Image, uint32_t width, uint32_t height, uint32_t Nx, uint32_t Ny, double *Norm);
What does your LabVIEW code look like?
Files attached. It simply reads in an image and calls the C library. This vi executes with a test-dummy dll that accepts the same inputs, and outputs a direct copy of the image; therefore, I can assume that the vi is fine and my inputs match the correct types.
Are you using arrays? Is the DLL assuming that the caller allocates memory?
Yes. I initialize two arrays in the calling vi and pass the pointer into the dll. Inside the dll, I dynamically allocate 2 arrays and deallocate them at the end of the function.
I am sure that the arrays are initialized correctly in the code and the correct value and type are passed into the dll. I made sure of this by commenting out the real code, and writing a simple function to copy the original array into the the resulting array. The results were favorable and the array was successfully copied in the dll and the vi finished without errors, and with correct copied values in the resulting array.
Is the DLL allocating memory for things like arrays that doesn't get released?
Yes, I dynamically allocate arrays that are used inside the dll only. These do not get used by my calling vi, and as far as I know, they are effectively deallocated at the end of the function.
Are you using the correct calling convention?
My dll is a .cpp file, but it is written as a C-callable function.

Hi Odie,
Not too familiar with XQuery rewrite, but i suspect by providing this hint, Oracle cannot optimize the query whatsoever.... tried this hint in my actual query and basically hangs.... I will attempt at opening an SR with Oracle...
the other option i'm looking at is checking the date ranges outside of xquery, and using a mix of xmltable, xmlexists and the SQL XML functions to reconstruct my xml.

Is it possible to get the caller object in a function call hierarchy ?

Hi,
I have a problem in hand for adding a new functionality to an existing code with MINIMAL code change. For this I need to get some extra information in a function call from its caller. And for this I do not want to change the signature of the method, as it requires a lot of code change. So I need to have a programming facility by which I can get the object from which the function was invoked. Some thing like "{code}this.CALLEROBJECT{code}".
Please let me know whether we can achieve this in JAVA. I wonder if such a facility exists in any programming language...
Thanks in advance.
Regards
Joby

No.
Youd have to buy it Germany or see if an Apple Authrorized reseller in Singapore could order you the keyboard.

Array argument in function call from 3DAnnots to host

Hi,
with Acrobat I am trying this: host.my_func(Array) from within an Annots3D script.
my_func is a pdf document function.
This is what I get in my_func:
1) console.println (Array): Arr_Element_1,Arr_Element2
2) for..in, console.println (Array[i]):
[object ScriptProxy]
[object ScriptProxy]
Array[i] is undefined
(actually I am passing a 2-element array).
So, the only way to work on Array in document my_func is to stringify Array (Array.toString()) and recreate an array. This may be a feasible way with litteral arrays but not as praticable with objects as you can image.
Have you got any workarounds?
Thanks

Global access to objects is indeed part of the sandboxing restriction. What you're trying to do is not transfer an object reference between scripts as you would when web pages interact with one another, but between interpreters. Allowing that would be a huge problem, as you could inject methods as well as properties.

PowerShell: Possible to return a DataReader object from a function call

I have to interact with several different db's. I was wondering how I could use a common Function for the connection and commnad params and have it return a DatReader object that I then could evaluate?
Example: (psuedo-code)
Function SqlCmd(Db, instance, command) {... return <DataReader onject>}
$Datareader= SqlCmd Db instance command
if ($Datareader.HasRows) {..to something..}
Thanks
TR

Hi TR,
This is possible by using the Dot.Net Sql objects. Below is a small function which takes a connection string and a SQL query string and returns a DataReader object:
function
Get-SQLData()
param (
   [string]$sqlConnectionString,
   [string]$query
# Create a connection to the OLAP Database
$connection
=
New-Object
System.Data.SqlClient.SqlConnection
$sqlConnectionString
$connection.Open()
if (!$?)
{throw
"Could not open the connection."}
$command
=
New-Object
System.Data.SqlClient.sqlCommand
$query,
$connection
$dataReader
=
$command.ExecuteReader()
,$dataReader
The most important thing to note in this entire function in the comma in front of the $dataReader at the end of the function. As PowerShell implicitly tries to unpack collection objects, this comma forces the collection to
be returned intact allowing you to use it as required. So here is an example of usage:
$dr
=
Show-SQLData
$sqlConnectionString
$query
if ($dr.HasRows)
   while ($dr.Read())
"$($dr[0]) $($dr[1]) $($dr[2])"
Hope that helps!

Partner for functional location of connecttion object

Hi Fritz,
Thank you for your support,
I would require to have a Migration Object : PARTNER for FUNCTIONAL LOCATION of CONNECTION OBJECT.
i know its a custom development can you help me with this context. To go ahead and develop this.
As i would require this to complete the data migration cycle for one part.
what are the requirement i need to take care to make this customization possible?
Regards,
Robert.

Hi Fritz,
Thank you for your response,
My need is to create a PARTNERS for the FUNCTIONAL LOCATION.
LET ME DESCRIBE IT.
WHEN I AM CREATING A FUNCTION LOCATION USING IL01, AS I ENTER A FUNCTIONAL LOCATION AND PRESS ENTER IN THE NEXT SCREEN.
AND
I NEED TO ENTER THE PARTNERS FROM THE DROP DROWN MENU GOTO ->PARTNERS
WHICH TAKES ME TO THE NEXT SCREEN WHERE I NEED TO FILL THE INFORMATION IN THE TWO FIELDS : FUNCT & PARTNER.
I need a partner for the functional location that i mentioned above.and i need to upload that information in through Emigall.
So my query was that can we customize that partner for this functional location and if yes, what should the constraints,
what are steps required? Do we require a custom service module?
Regards,
Robert.

Using type for function in sql

CREATE OR REPLACE

CREATE OR REPLACE function in_list( p_patseq in number ) return InListType_number
as
l_number number default p_patseq ;
l_data InListType_number := InListType_number();
begin
loop
exit when l_number is null;
end loop;
return l_data;
end;
SELECT p.pat_seq, p.diagnosis_type, ct.code_value || ' ' || p.alt_description as diagnosis_desc
FROM patient_diagnosis p,
(select * from code_set , code_set_type
where code_set.code_set_type_seq =code_set_type.code_set_type_seq) ct
WHERE p.enterprise_seq = (select enterprise_seq from org_lookup where organization_seq = 0 and rownum = 1)
and p.diagnosis_code_seq = ct.code_set_seq(+)
and (p.diagnosis_type LIKE 'A%' OR p.diagnosis_type LIKE 'W%')
and p.PAT_SEQ IN (select /*+ CARDINALITY (t ) */* from table( cast( in_list (list of pat_seq here like 12345,12344,345666,etc over 1000 counts of pat_seqs)
as InListType_number ) ) t)
this gives me
ORA-00939: too many arguments for function
can someone advise? thanks

Well IN_LIST takes a single parameter of type NUMBER and you are passing in
12345,12344,345666which is patently multiple numbers. I think what you want to do is pass in a string ' 12345,12344,345666' and have a function TO_LIST() that parses the string and spits out numbers. Fortunately for you John Spencer has posted Re: Splitting the values in one column.

Dynamically catch a function call from an object at runtime

Hi,
I have a bit of an interesting question.
Say I have a dynamic object named Foo. It may have a set of explicitly defined functions:
public function helloWorld():String
     return "hello world";
public function get name():String
     return "My Name";
etc.
I want to be able to create a further function
public function handleFunctionCall(functionCall:String, args:Array):*
     trace("Function: " + functionCall + " was called with the arguments:");
     for(var i:int=0; i<args.length; i++)
          trace(args[i]);
The purpose of this is so that I can declare the object Foo and then call any function and handle it accordingly at runtime.
e.g.
var foo:Foo=new Foo();
foo.bar();
foo.whathaveyou();
foo.whatever();
Hope someone can point me in the right direction.

I'd be interested to know more about what you are trying to achieve, but the code below should work:
public function handleFunctionCall( functionName : String, args : Array ) : *
   var functionToCall : Function = this[ functionName ];
   return functionToCall.call( this, args );
For alternative approaches you may want to take a look at behavioural design patterns. The command or strategy pattern may suit your needs.

Our requirement is that we are summing up the field "Grant_Amount" which occurs multiple times in the source structure and the sum is mapped to the field "Sum' on the target side.The stylesheet is working fine in stylus studio but whe imported into XI the above mentioned error is being thrown.Can any one one please help me solving this issue.

If you are using below mentioned java code for Convert method, then see you are passing a String Array, but in below statement:
<xsl:value-of select="Trans:Convert(//Grant_Amount)"/>
This is just a single value i think, you have to pass an array with values 100,200,300. Pls check it.
