PRB: Some Visual J++ Samples Report Errors when Compiling

ID: Q162119

The information in this article applies to:

Microsoft Visual J++, version 1.0, 1.1

SYMPTOMS

Compiling some of the samples on the Visual J++ CD may result in the following error messages.

JavaCallingCOM

   C:\Msdev\samples\microsoft\javacallingcom\usecom.java(10,8) :
   error J0051: Undefined package 'comserver'

OLEControls

   C:\Msdev\samples\microsoft\olecontrols\orgchart.java(8,8) :
   error J0051: Undefined package 'msoutl32'

HTMLControls

   C:\Msdev\samples\microsoft\daosample\simpledao.java(12,8) :

CabAndSign

   C:\Msdev\samples\microsoft\cabandsign\javabeep.java(31,2) :
   error J0049: Undefined name 'IBeeper'

CAUSE

The samples listed above all require Java descriptions of the COM components they use. The build errors are generated if the Visual J++ Java Typelib Conversion Utility is not run on the type library required by the samples.

RESOLUTION

You can create the Java description of COM components by running the Java Type Library Wizard from within the IDE under menu Tools.Java Type Library Wizard, or by running JavaTlb.exe from an MS-DOS command line.

Help and the Readme.html for the samples listed above describe the steps required to successfully compile and run the samples. Following the steps described in Help and each individual Readme.html file for the specific sample should resolve the errors. You can find the Readme.html file in the directory where each individual sample is located.

You can find these steps in the Readme.html under "How to use this sample," which includes a topic on "Creating a Java Description of COM Components."

The Readme.html also has information that should help in troubleshooting problems with the specific sample.

STATUS

This behavior is by design.
