Hi!
I've made a simplest java application. An empty class Test.java stored in
package "saa.test". I've compiled it using jvc.exe /target:library
/out:Test.dll.
It was done fine. The Test.dll was created without errors.
But when I tried to insert a reference to the Test.dll assembly an error
message occured telling me that it is not a valid one.
If I compile the Test.java using the .NET IDE this error does not occurs any
more.

Since I want to use the command line compiler in batch mode,
can anyone help me to solve this problem?

Thanks,

Radu

I responded bellow at some point :

I suppose you have created the client using a new J# Project.
I have not tried this. I tried to link the library in a client written in
VB, in a VB.NET project (since the .dll does not depend on language) and
doesn't work.
This is working for you too?

I will try using a J# project to see if it is work or not.

Thanks,

Radu

P.S. Could be what's happened to me a bug of an older Visual Studio version?
It seems I have an older version of Visual Studio than you ...

Sorry,
I think I was not clear enough.
I managed to make a reference and include the .dll in an .exe using command
line tools, like you.
But I cannot include the .dll as reference in a VB.NET Project (an error
occurs).
This is usefull not just for compilation (which can be solved using command
line tools) but either for IntelliSense, you know.
If you already tried, using a VB.NET project it seams that it was a still
unknown problem on my machine ...
If you don't tried yet please try to add a reference, in a VB.NET to the
..dll (which was compiled only with the command line tool and has no other
files but .java files in it).

Thanks for all,

Radu

I've tried the following example

}
public String getMessage()

Inherits System.Windows.Forms.Form

Public Sub New()
MyBase.New()

End Sub

'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer

'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.

'Form1

Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.ClientSize = New System.Drawing.Size(292, 266)
Me.Name = "Form1"
Me.Text = "Form1"

End Sub

#End Region

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim t1 As Test01

t1 = New Test01("Un mesaj din java!")
MsgBox(t1.getMessage())
End Sub
End Class

---- end file

---- file root\Module1.vb

Module Module1
Public Sub main()
Dim f1 As Form1
f1 = New Form1
f1.Show()
End Sub
End Module

---- end file

----- file root\test.bat ----

vjc /recurse:saa\*.java /out:Test2.dll /target:library
vbc *.vb /target:exe /reference:Test2.dll /out:testVb2.exe
testVb2.exe

----- end file

And it works!

But when I want to import the library Test2.dll in another VB.Net project
an error message occurs:

"A reference to ...\root\Test2.dll could not be added. This is not a valid
assembly or COM component. Only assemblies with extension 'dll' and COM
components can be referenced. Please make sure that the file is accessible,
and that it is a valid assembly or COM component."

I think the .dll was not used by any other program, to lock it, for example.
So I cannot explain myself why it is occured.

Thanks for your patience,

Radu

I have Visual Studio 2003 ...
But I think I had previous a Microsoft .NET Framework on an earlier version
(because that I told you that maybe I have an earlier version).
Maybe when I installed the Visual Studio 2003 there was some files from the
older version which remains ?! I don't know ...
I will manage to reinstall it from scratch ...

Thanks for your help,

Radu
