did i miss some? or is it about the method handle() - which takes no arguments? in this case - override or modify it.
by the way - why do you start variables with a capital letter?

I have a Handler.java class in which i need to use a function handler() which should take in the parameters from Connect.java file's method handleConnect() as input .Also handleConnect() return type is a class(Response)I dont know how to accomplish that..?can u please help me and also explain how is that to be done.?

Ah - now I see what you mean (or at least I think I do so).
You fault was not to follow simple rules. Use the naming conventions - use Checkstyle.
If you do so, you will realize, that Response is a typ of object and not a variable. You need to differ between what is a name of a variable/member (starts with lower character) and what is a type (starts with upper character).
So if you write your method handle() in class Handler like this:
public void handle(final Response aResponse){
}
...it should do the job. Then you can use the Object Response and squeeze your info from it.

Function handle() needs to be rewritten as handle(function arguments here) . Perhaps you have not explained your problem too clearly.
Just say 'NO' to evaluated arguments for diadic functions! Ash

most servers have a log file. Did you look for it?
|
|
|
|
|
did you checked that there is no other server or program which is using same port as your glassfish, besides as a tip glassfish is stupid ,it gives problem many times or you can say its still incomplete or buggy, better use tomcat(not installer for netbeans) or sun java application server.
|

If you take a look to Server Tab in NetBeans IDE, probably you'll find that needs an inexistent file into ../domains/domain1 folder. Try to start it from IDE without any project (Start Server) or manually from <<install_dir>>/glassfish/bin/startserv.
Best Regards

May be that you are having another server listening on the same port. Stop other services on the port and then start the GlassFish server. If there is no other problem it should run cool.

I am having a ComServer, and its outlined functions are implemneted in C++. Below is the Cpp function.
HRESULT cIntuneServer::GetActiveProjectName( BSTR* nameOfProject)
{
CComBSTR projectName(L"\\Default\\");
*nameOfProject = projectName;
return S_OK;
}
I tried to implement the same function in Java:
JIString outStr = new JIString("");
dispatch.callMethod("GetActiveProjectName", new Object[]{outStr});
System.out.println("Out String = "+outStr.toString();
OUTPUT:
Out String = [Type: 1 , []]
How do i implement this in java?, I knew i am doing something worng, how do i get the BSTR* value to the OutStr in Java?

I'm not a JNI expert but a quick google search suggests this is not so straight-forward. Here is how one person describes it:
a BSTR is a funky kind of Microsoft String object, and converting between them and C strings is complicated (and from there to Java Strings adds yet another step)
Google "BSTR java string" brings up lots of articles about it. One of them may help.

My guess is the question is incomplete.
Java doesn't access random dll methods.
One must use JNI to do it.
I believe the poster is using a dynamic 3rd party wrapper for JNI because a similar post with info to that effect showed up in the Oracle Java forums.

You are right jschell, i posted it at oracle forums too, the thing is no one was actually helping at the J-Interop forum, so i have been posting at some other good forums for help etc...
My only aim is to read a string from a cpp function, doesn't matter if i am using a wrapper. At least if someone could help me how to do this using Native or Standard Java without a wrapper like an example or something. Maybe i can proceed from there.

Having a C++ written class, you need to convert it into a shared library (so or DLL); for example, suppose you can embed the snippet you are using in C++ (the one you posted before) into a function like LPSTR yourSnippet(). You can dynamically link the generated shared library from Java using: static {System.loadLibrary("libreria.dll");} and declaring method as native : native String getCadena();
When building wrapper header file (with javah) you'll see in .h file type corresponging :
JNIEXPORT jstring JNICALL <<java_function_name>>_getCadena (JNIEnv *, jobject)
You just have to write a C file including the generated header file you builded with javah, and implement <<java_function_name>>get_Cadena function with: return yourSnippet(); . Just compile and link them as shared library 'libreria.dll' and you got it!
I hope helped you.
Best Regards.

Jinterop is a Java library that by its very nature provides direct access to existing shared libraries. It does that by using dynamic access (via OS calls) in it own jni library.
Thus one does NOT need to create another shared library when using that API.
Jnative is another example of the same sort of thing.

Google "postgresql glassfish". There are a number of articles that tell you how to do it.

Hi,
I have a web application which has a simple java class.
In my java class I have a function that returns Collection<classt>.
For example:
Collection<classt> coll = funcA();
I want to somehow print the contents of the coll collection to the screen - this is for debugging purposes.
How can I do this?
I tried throwing an exception - RuntimeException - but it only accepts a string.
I tried converting the collection to a string, but it doesn't work:
Collection <classt> col = funcA();
String str1 = "";
Object[] arrCol = col.toArray();
for (int i = 0; i < col.size(); i++)
{
str1 = str1 + arrCol[i]+ " ";
}
Is there another way I can view during runtime the contents of the collection?
By the way, I am very new to java - i am a C++ programmer...
Thanks!

Did you try the toString method ?
|
|
|
|
|
toString on what? on arrCol[i]?
arrCol[i].toString() gives me a cannot find symbol error.
|
|
|
|
|
|
Do you mean:
Collection col = funcA();
String sCol = col.toString();
If so it doesn't work...
If it's not what you meant, I would appreciate it if you could write some code since I am very new to Java...
