Apache Axis2/C Installation Guide (Windows)

Posted on May 18, 2018 by admin

First

http://archive.apache.org/dist/ws/axis2/c/1_6_0/axis2c-bin-1.6.0-win32.zip
ftp://ftp.zlatkovic.com/libxml/libxml2-2.7.8.win32.zip
ftp://ftp.zlatkovic.com/libxml/iconv-1.9.2.win32.zip
ftp://ftp.zlatkovic.com/libxml/zlib-1.2.5.win32.zip
http://archive.apache.org/dist/httpd/binaries/win32/httpd-2.2.25-win32-x86-openssl-0.9.8y.msi

Install Axis2/C

Extract the binary distribution to a folder of your choice.(example: C:\axis2c-bin-1.6.0-win32)
Copy the iconv.dll, libxml2.dll and zlib1.dll to C:\axis2c-bin-1.6.0-win32\lib
Set the variable AXIS2C_HOME to the deploy folder (C:\axis2c-bin-1.6.0-win32)
Add the path to lib directory to the PATH variable (%AXIS2C_HOME%\lib)

Install Apache 2.2

Copy C:\axis2c-bin-1.6.0-win32\lib\mod_axis2.dll C:\Apache22\modules\mod_axis2.so
Edit the Apache2’s configuration file (generally httpd.conf) and add the following directives
LoadModule axis2_module modules/mod_axis2.so
Axis2RepoPath C:/axis2c-bin-1.6.0-win32
Axis2LogFile C:/axis2c-bin-1.6.0-win32/logs
Axis2MaxLogFileSize 40
Axis2LogLevel warn
Restart apache2 and test whether mod_axis2 module is loaded by typing the URL http://localhost/axis2/services in your Web browser
