[kaffe] How I can solve the java.lang.ClassNotFoundException

[정종진_KETI]

Hi kaffe export.

I have built kaffe(V1.07) successfully. Building Kaffe made a kaffe tree in the directory /usr/local/kaffe.



First, I compiled jikes 1.18 with following opions

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

./configure prefix=/usr/local/bin/jikes

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

It made a jikes tree in /usr/local/bin/jikes



Next I compiled kaffe with the following options

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

export QTDIR=/usr/local/qt-3.1.1

CC=mips-linux-gcc CFLAGS="-mcpu=r5000" \

CXX=mips-linux-g++ CXXFLAGS="-mcpu=r5000" \

KAFFEH=/usr/local/x86kaffe/bin/kaffeh \

ac_cv_c_char_unsigned='no'  ac_cv_alignmentof_voidp='4' \

ac_cv_c_bigendian='yes'  ac_cv_sizeof___int64='0' \ 

ac_cv_sizeof_int='4' ac_cv_sizeof_long='4' ac_cv_sizeof_long_long='8' \

ac_cv_sizeof_short='2' ac_cv_sizeof_voidp='4' 

~/kaffe/configure \

--with-engine=intrp \

--with-jikes=/usr/local/bin/jikes/bin/jikes \

--target=mips-linux-gnu --host=mips-linux-gnu --build=mips-linux \

--with-includes=/usr/mips-linux/include --with-libraries=/usr/mips-linux/lib \

--with-awt=qt --with-qtdir=/usr/local/ qt-3.1.1 --without-alsa --without-esd 

--disable-sound –enable-debug --disable-xprofiling --enable-xdebugging \

--disable-feedback --without-profiling --without-stats --disable-gcj

cf) 1. QT Version 3.1.1

      2. OS : Linux (2,4,17)

      3. CPU : mips-R5000
      4. cross-compiler toolchain : SGI cross-compiler tool chain
                                                     mips-linux-gcc(egcs-2.91.66), mips-linux-g++, etc..

      5. jikes – 1.18 (it is not updated from CVS. It is just a tar file in jikes-homepage)

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

After I built kaffe successfuly, I copied kaffe tree (usr/local/kaffe) in the same directory of target. 

I tested test files. I succeeded the test of files in /test/regression. 

But I found the following message.



> Warning: Unrecognized version number 47/0 in classfile.



I can’t know why the message happens. Is it related with jikes 1.18?  Must I update jikes from jikes CVS Repository?

Also the awt test files doesn’t work except TextEdit. 

When I tested Cals, Unico and WidgetsDemo,  I cound found the following error.

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

java.lang.ClassNotFoundException: /Java_Test/awt/Cals/Cals

        at kaffe.lang.SystemClassLoader.findClass0(SystemClassLoader.java:native)

        at kaffe.lang.SystemClassLoader.findClass(SystemClassLoader.java:150)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:98)

        at java.lang.Class.forName(Class.java:73)

        at java.lang.Class.forName(Class.java:42)

Caused by: <null cause>

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

I can’t solve this problem. Is this error related with jikes?

When I had a jikes, doesn’t other java compiler ( kjc, kopi,etc) need?

Please give me a solution.

Thanks.
