problem with char in Visual COBOL for Eclipse

[Migrated content. Thread originally posted on 20 January 2012]

Greetings.

New to JVM COBOL and this forum.

Wondering if anyone can shed any light on what I am experiencing in Visual COBOL for Eclipse.

I have created a .java file in the Visual COBOL for Eclipse IDE and it seems I cannot save the file when I try to populate a byte in a byte array with a cast of a char to a byte. This code construct works elsewhere in java.

byte[] crtioDataByteArray = new byte[16240];

crtioDataByteArray[0] = (byte) 'a';

I get the same error if I even define a char as below:
char OPENED = 'O';

When I attempt to save the file I get a dialogue box indicating

"Save Failed
java.lang.NullPointerException"

and the detail button offers no further explanation.

Thanks

I am really not sure what you are referring to here.

On which platform are you running, Windows, Linux?
Are you using the Dev Hub product to compile under Unix?

It sounds as if you are using the Eclipse IDE to create a Java project not a COBOL project is that correct?
I used the Visual COBOL Eclipse R4 product to create a new Java class in a Java project and I successfully added the code that you are getting an error on.

Can you please explain the exact steps that you are taking so that I can try to reproduce this error?

Be aware that the Java compiler and Eclipse IDE themselves are not Micro Focus products.
Visual COBOL Eclipse is the plugin that Micro Focus supports that allows you to create COBOL applications using the Eclipse IDE that will compile to either native code or to JVM byte code.

Thanks.

Thanks for the response, Chris.

Sorry I did not include all the information.

I am working on Windows.

Yes, I created a java project to add java classes to call and be called from separate JVM COBOL project members.

I do realize that Eclipse is separate from JVM COBOL.

For some reason char constants seem to cause problems. I am getting another error (when I build the java project) when the java class references an existing java class which contains char constants.

"Problems occurred building the selected resources.
Errors running builder 'Java Builder' on project 'LawsonAppsJavaProject'.
org/eclipse/jdt/internal/compiler/impl/CharConstant"

I will explore further given the new info in the build error...

Chris,

BTW version of Eclipse I am using is also "Micro Focus Visual COBOL R4 for Eclipse"
