[javaCompiler-users] Can't find default package 'xxxx'. Check the CLASSPATH environment variable and the access to the archives

[Ewald P. <ewa...@gm...>]

Hi,

I tried JavaCompiler today first with a HelloWorld-Example (it worked) 
then with a more complicated Swing-application I wrote in the last years.

There was the error "Can't find default package 'cica0.languages'. Check 
the CLASSPATH environment variable and the access to the archives."

However, cica0.languages is my own subpackages, which I of course 
included in the page 1/3 sources (source, not .class-files).

--Here's the project file:--------------------
projectType=ch.mtSystems.javaCompiler.model.projects.ManagedAwtSwingProject
dir=D:\Eigene_Dateien\cica0\src
dir=D:\Eigene_Dateien\cica0\src\cica0
dir=D:\Eigene_Dateien\cica0\src\cica0\languages
mainClass=cica0.App#D:\Eigene_Dateien\cica0\src
outputDir=D:\Eigene_Dateien\cica0\native
outputName=Cica-native
java5Preprocessing=false
useJni=false
ignoreMissingReferences=false
omitWindows=false
omitLinux=true
omitStripping=false
omitPacking=true
iconFile=null
useIcon=false
hideConsole=false
beepWhenDone=true
---------------------------------------------

Do you have any ideas what could be the problem/solution here? Thanks.

Thanks also in general for this application.

regards
Ewald

Actually, I wouldn't expect too much if it's more than a "hello world" 
swing application. AWT and Swing is not very advanced in gnu classpath 
and swingWT...
Anyway, this seems to be another problem. Can you create a simple 
failing class? Maybee the "0" in the package name is the problem...

Have you tried to compile from the class files?

Ah, and by the way: Directories are recursively searched. So adding 
"dir=D:\Eigene_Dateien\cica0\src" is enough...

Although I'm not new to Java programming in general I have neither 
experience with "free" implementations of it nor with compiling to 
native code. So I am a bit confused about your statement; 
http://www.kaffe.org/~stuart/japi/htmlout/h-jdk14-classpath.html states 
that swing and awt are implemented nearly 100 % in gnu classpath?

--------------------

There were similar errors which I could avoid by commenting out some 
method calls. It looks like some (quite a few actually) methods are just 
not implemented in SwingWT, just as you said before.

Alright, thanks. Looks like I wasn't up to date with gnu classpath 
itself. In this case, the problem reduces from gnu classpath and GCJ to 
GCJ only.
The main GCJ developpers are pretty much only interested in compiling 
java to shared executables on linux.
Because there's no active windows maintainer, building shared windows 
executable is currently broken.
Because no one ever looked into it, the gnu classpath AWT/Swing 
currently only works with shared executables on linux (static 
executables on linux won't work and noone ever tried gnu classpath 
AWT/Swing on windows).

That leaves me no other option than use swingWT instead of the gnu 
classpath implementation...

Yes, swingWT doesn't cover all you needs. I suggest to either work on 
swingWT (it's open source) or (what I prefer) change to SWT directly...

Ah, and thanks for reporting the bug. Looks like my parsing of the 
package from source files has a bug. I'll investigate that...
