How to use Axis2c to generate C files from WSDL file

Question

I want to use a webservice in C code. I am trying to make a client. I need something to do what Axis2java does and generates the classes from a wsdl files. I found that Axis2c makes (.c) files generated from wsdl file. I downloaded it from here . unzipped it. I created the environment variable for AXIS2C_HOME and I created AXIS2C_CLASSPATH. but I can't make it work.

when I type this command :

WSDL2C -uri -ss -sd -d none -u -f -o

I get this error :

echo off
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C

how can I solve this problem. and please tell me how to use this Axis2c tool properly.

Thank you in advance.

@loentar : I installed Axis2/Java and I set the environment variable for it. now I run the wsdl2c.bat I get this :

E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>WSDL2C.bat

after that I run this command :

E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>WSDL2C.bat -uri hello.wsdl
-u -uw

E:\dev\Tools\axis2c-bin-1.6.0-win32\bin\tools\wsdl2c>echo off
Unrecognized option: -uri
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

what can I do ? I'm using windows 8 by the way.

Answer 1

I set the envinroment variable for JAVA_HOME, AXIS2_HOME, AXIS2C_HOME, and added their lib folder to CLASSPATH. after running this command: WSDL2C.bat -uri hello.wsdl -u -uw I got this message:

echo off 
Error: Could not find or load main class org.apache.axis2.wsdl.WSDL2C

I found the solution myself. :) I double checked if I had created the environment variable for AXIS2_HOME and I saw that it is there, correctly. in spite of it's existence I tried to set it again in command prompt. so I typed:

SET AXIS2_HOME=E:\dev\Tools\axis2-1.6.2

then I typed the command for WSDL2C code generator:

WSDL2C.bat -uri hello.wsdl -u -uw

And BAM ! it worked properly. Now I can generate C files from WSDL file.

In addition to Axis2/C you must have Axis2/Java installed.

AXIS2_HOME must point to Axis2/Java installation.

For details please see README of codegen.

The complete list of commands to create and compile client is:

# create stubs
sh $AXIS2C_HOME/bin/tools/wsdl2c/WSDL2C.sh -uri Calculator.wsdl -u -uw

# implement main() in src/your_client.c
# see samples/codegen/client/calculator for example

# compile and link client
gcc -o calculator_client src/*.c -I$AXIS2C_HOME/include/axis2-1.6.0 -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_parser -laxis2_engine -lpthread -laxis2_http_sender -laxis2_http_receiver -ldl -Wl,--rpath -Wl,$AXIS2C_HOME/lib
