Q.5. How do I use the JDK1.1 features from Visual J++?
A. Visual J++ does not provide support for JDK1.1. In order to use
JDK1.1 you need to install the SDK2.01 for Java, whose VM and class libraries
provides JDK1.1 support. Once you install the SDK2.01 for Java, you can
integrate it with Visual J++ 1.x. For more information about how to use SDK2.01
from within Visual J++, refer to the Microsoft Knowledge Base article
183712, HOWTO: Installation Instructions for SDK for
Java.
Q.6. After installing IE4 in the integrated desktop mode, I am
unable to debug Java applets with Visual J++ 1.1. Why?
A. For more
information about this refer to the Microsoft Knowledge Base article
167998, FIX: Cannot Debug Visual J++ Programs on IE
4.0.
Q.7. When trying to compile a simple Java program, I get the
following error:
error J0136: Public class 'identifier'
should not be defined in 'identifier'
A. There could be several
reasons for this error. If your Java class name is different than the file name
it is present in, then it fails with this error, for example:
public class myclass { }
When it is saved in
a file that is not Myclass.java. Also remember to use the correct case for the
names.
The J1036 error also occurs when there is more than one
"public" class declared in a single .java file. This is not allowed. There may
be only one public class in a .java source file. If you need to write multiple
public classes, they must each be in their own .java file.
Q.8. Why
does the MS-DOS command prompt window disappear after my Java application
terminates when executed from the Developer Studio IDE?
A. For more
information about this, refer to the Microsoft Knowledge Base article

After Running Jview.exe.
