Hello every one,
I have a problem that i recieve null reference object exception in system.dll when i want to access Method of the dotnet application through java application. Below i give explaination of my work. That is my first corba complient application. I have follow the instructions as mentioned in the article below
http://www.codeproject.com/csharp/dist_object_system.asp
First i have created the server appplication named IIOPServer, code of this server application are written as follows,
IiopChannel objChannel = new IiopChannel(7999);
ChannelServices.RegisterChannel(objChannel);
RemoteMethods objMethods = new RemoteMethods();
RemotingServices.Marshal(objMethods , "remoteMethods");
and my RemoteMethods Class has the following methods
public double Add(double num1 , double num2)
{
return num1 + num2;
}
public double Subtract(double num1 , double num2)
{
return num1 - num2;
}
public double Divide(double num1 , double num2)
{
return num1 / num2;
}
public double Product(double num1 , double num2)
{
return num1 * num2;
}
after creating the server application, i creat its IDL file using IIOPNet utility, named as "CLSIDLGenerator" by writing the following lines in the command prompt ,
c:\iiop\iiopnet\CLSToIDLGenerator\bin\CLSToIDLGenerator RemoteMethods
-o c:\working\projects\IIOP\IIOPServer c:\working\projects\IIOP
\IIOPServer\bin\Debug\IIOPServer.dll.
Its create RemoteMethods.idl file in IIOPServer directory.
Then i convert this IDL file to java files using IDLJ utility of java, by wtitting the following lines.
C:\jdk1.4\bin>idlj -td c:\working\projects\iiop\iiopclient -i c:\jdk1.4\lib
-i c:\iiop\iiopnet\CLSToIDLGenerator\Bin C:\Working\Projects\IIOP\
IIOPServer\RemoteMethods.idl
its create five java files in the IIOPClient folder.
In the next step i write code of the IIOPClient application in java. Code the IIOPClient.java is as follows,
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import Ch.Elca.Iiop.GenericUserException;
import IIOPServer.*;
class IIOPClient
{
public static void main(String[] args)
{
RemoteMethods m = null;
try {
InitialContext ic = new InitialContext();
Object obj = ic.lookup("remoteMethods");
m = (RemoteMethods) PortableRemoteObject.narrow(obj, RemoteMethods.class);
System.out.println("Addition: " + m.Add(20,4));
System.out.println("Subtraction: " + m.Subtract(20,4));
System.out.println("division: " + m.Divide(20,4));
System.out.println("Multiplication: " + m.Product(20,4));
} catch (Exception e) {
System.out.println("Exception: " + e.getMessage());
}
}
}
this file is saved in IIOPClient folder. Then i compile this java file to create its class file. And in next step i am going to run IIOPClient application by writting the following line of commands
C:\jdk1.4\bin>java -Djava.naming.factory.initial=com.sun.jndi.
cosnaming.CNCtxFactory -Djava.naming.provider.url=
iiop://localhost:7999 -classpath c:\working\proj
ects\iiop\iiopclient IIOPClient
but it could not find RemoteMethods object on port 7999 and give an error that
"NullReferenceObject" in System.dll
Good Luck

you try with cells[1].controls[0] probably this will give you the required value.

Hi
here
1) if your machine setting is as per the islamic.
then
DateTime dtNow = DateTime.Now;<br />
string strdate = dtNow.ToString("g",System.Globalization.CultureInfo.InstalledUICulture);<br />
or you can specify the
2)
string strdate = dtNow.ToString("g",System.Globalization.CultureInfo.CurrentUICulture);<br />

How to resize a datagrid at run time using Asp.net and VB as code behind.

Hello
I use vs 2005. Can anyone tell me where i can find a tutorial to do something like www.orca.com main animation(the world zone selection) ??

I'm trying to publish an ASP.NET application with VS 2005, and after I choose the folder everything goes smoothly and the Output window tells me
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========<br />
========== Publish: 1 succeeded, 0 failed, 0 skipped ==========
But the folder it's supposed to publish to is empty.

IMHO, there are a couple of things that you may try:
+ Choose the File System for the Target Location if you don't.
+ Use the ASP.NET compile tool: aspnet_compiler.exe.
+ Try with a new location.
+ Try publishing with a simple application.

I do.
minhpc_bk wrote: Try with a new location
I tried different locations. Same result.
minhpc_bk wrote: Try publishing with a simple application
This is just the thing. It doesn't work for this applciation. For others it's ok. Someone said on the asp.net forums to create a new project and add the files from the ex-project one by one. This has the effect on working again for him. Eventually if everything else goes wrong, I'm gonna try it, though it's a big project

Fixed it. I ran aspnet_compiler with the -errostack directive in the shell prompt and the output was the following error: HttpParseException: Unexpected end of file looking for </link> tag.
Aparently some of my pages were not XHTML compliant. After closing properly the tags, everythign runs smoothly and the website publishes correctly.
But what the heck did that error emerge in the first place? I have no doctype in my pages specifying that my pages should be XHTML compliant.

Glad you figured out the cause.

Do you have any xhmtl conformance setting in the web.config file? Also, in the VS do you choose the xhtml in the Target Schema for Validation? Do you see any error in the Error List window when you build the web site in VS?

No.

Unchecked

No errors.

I have created a dynamic control (Button) inside a click event of another button. But, I'm not able to trigger the click event of the dynamically created button! I know there is something goin on with the page cycle, dynamics,...Can anyone post me a simple, easily understandable solution to my problem?
Thanks
|
|
|
|
|
Have you created an event handler for the dynamic button to associate itself to?
Nila Fridley

|
|
|

You need to make sure two things:
+ The dynamic button is readded on postback.
+ The dynamic button is added before the postback event is processed, if it occurs too late in the page life cycle, the event does not get fired, and as a result the event handler does not execute. You can easily find the sample code out there, clickety[^]
