gcj and apache

Thu Sep 9 14:45:00 GMT 2004

Hello,
I wrote a GCJ C program and a Java class (see the
attachment for details, java2.cpp and Sigclass.java).
I tried to let the C program to call the "main" method
of the Java class by putting the path of compiled Java
class into CLASSPATH. 
For example, in this way:
export CLASSPATH=/home/zhiqing/make/example3
Directory "example3" contains the compiled class
single/Sigclass.class
The execution of the compiled C program is successful.
(Main procedures:
 gcc java2.cpp -o java2 -lgcj -lstdc++
 javac single/Sigclass.java
 ./java2 single.Sigclasss www
)
If I compressed the class "single/Sigclass.class" into
jar (say single1.jar), the result is also successful. 
(
 jar -cvf single1.jar single/Sigclass.class
 export
CLASSPATH=/home/zhiqing/make/example3/single1.jar
)
However, if I copied the GCJ C program to an apache
module (wrote in GCJ C, no errors occur in
compilation, mod_permis.cpp) and ran the apache after
set CLASSPATH:
export CLASSPATH=/home/zhiqing/make/example3/ or
/home/zhiqing/make/example3/single1.jar
The error_log of the apache:
....
Unhandled Java exception:
java.lang.ClassNotFoundException: single.Sigclass not
found in
[file:/home/zhiqing/make/example3, file:./, core:/]
....
or
Unhandled Java exception:
java.lang.ClassNotFoundException: single.Sigclass not
found in
[file:/home/zhiqing/make/example3/single1.jar,
file:./, core:/]
The apache in my computer is version 1.3.29 compiled
with the same gcc (gcc (GCC) 3.3.2) as mentioned
above.
Why gcj can not search its CLASSPATH in this case? Any
advice or suggestion would be appreciated.
