MORE INFORMATION

Q.1. The Visual J++ 1.0 Setup program does not run. Do I have a bad CD-ROM?

A. For more information on this refer to the Microsoft Knowledge Base article Q157877, PRB: Visual J++ Requires a Protected Mode CD-ROM DriverObject in Java.

Q.2. When I attempt to extract sample programs using the online Help in Visual J++, I get a dialog box that reads "Infoview automation object," "error accessing sample data."

A. For more information on this refer to the Microsoft Knowledge Base article Q171844, FIX: InfoViewer Cannot Download Samples if IE4.0 is Installed.

Q.3. When I try to compile simple Java applets or applications, I get the following error J0051:

Undefined package 'lang'.

A. For more information on this refer to the Microsoft Knowledge base article Q169799, PRB: Error J0051: Undefined package 'lang'.

Q.4. When trying to debug from Visual J++, a dialog box appears with the following message:

Failed to connect to Java debug manager. Please make sure your JAVA components are correctly installed.

A. For more information on this refer to the Microsoft Knowledge Base article Q172201, PRB: Problem Connecting to Debug Manager in Visual J++.

Q.5. When trying to install SDK2.01 for Java using the Setup Wizard, I get the following error during installation:

Invalid Picture Error when running SDK setup.exe on Win95

A. Try installing SDK2.01 using the self-extracting file also available at

http://www.microsoft.com/java/.

When installing this manner, make sure to run clspack -auto manually to install the Classes.zip from the package manger. For more information on SDK2.01 setup, refer to the Microsoft Knowledge Base article Q183712 , HOWTO: Installation Instructions for SDK for Java.

Q.6. 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 on how to use SDK2.01 from within Visual J++, refer to the Microsoft Knowledge Base article Q183712, HOWTO: Installation Instructions for SDK for Java.

Q.7. 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 on this refer to the Microsoft Knowledge Base article Q167998, FIX: Cannot Debug Visual J++ Programs on IE 4.0.

Q.8. 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.9. 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 on this, refer to the Microsoft Knowledge Base article Q169798, HOWTO: Prevent Output Window from Closing After Running Jview.exe.
