AXIS2C启动虚拟机示例

创建WSDL文件

创建eucalyptusNC.wsdl

<?xml version="1.0" encoding="utf-8"?>

<wsdl:definitions targetNamespace="http://localhost/axis/eucalyptusNC" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://localhost/axis/eucalyptusNC" xmlns:intf="http://localhost/axis/eucalyptusNC" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<wsdl:service name="eucalyptusNC">

<wsdl:port binding="impl:eucalyptusNCSoapBinding" name="eucalyptusNC">

<wsdlsoap:address location="http://localhost/axis/eucalyptusNC"/>

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

配置环境变量

AXIS2_HOME为axi2的放置目录

AXIS2C_HOME为axis2c的安装目录

export AXIS2_HOME=/home/eucalyptus-src-deps/axis2-1.4/

export AXIS2C_HOME=/usr/local/axis2c/

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/axis2c/lib/

export PATH=$PATH:/usr/local/axis2c/bin/tools/wsdl2c/

生成服务端代码

sh WSDL2C.sh -uri eucalyptusNC.wsdl -sd -ss -d adb -u -f -o server

在axis2_skel_eucalyptusNC.c文件adb_ncRunInstanceResponse_t* axis2_skel_eucalyptusNC_ncRunInstance (const axutil_env_t *env ,

adb_ncRunInstance_t* ncRunInstance )

函数中添加如下代码

adb_ncRunInstanceResponse_t* ref=NULL;

char *cmd;

cmd=strdup(adb_ncRunInstance_get_cmd(ncRunInstance,env));

printf("cmd :%s/n",cmd);

ref=adb_ncRunInstanceResponse_create(env);

RunInstances();

adb_ncRunInstanceResponse_set_result(ref,env,"Pending...");

return ref;

其中RunInstances();包含在RunInstances.h头文件中，这个文件是启动虚拟机的代码

RunInstances.h源码如下：

#include <stdio.h>

#include <stdlib.h>

#include <libvirt/libvirt.h>

void closeConn(virConnectPtr conn)

{

if(conn!=NULL)

virConnectClose(conn);

}

int RunInstances()

{

virConnectPtr conn=NULL;

virDomainPtr dom=NULL;

conn=virConnectOpen("");

if(conn==NULL)

{

fprintf(stderr,"Fail To Connect Hypervisor/n");

return 1;

}

const char *xmlconfig="<domain type='xen' id='18'>/

<name>i-52C5093E</name>/

<os>/

<type>linux</type>/

<kernel>/var/lib/xen/images/kernel</kernel>/

<initrd>/var/lib/xen/images/ramdisk</initrd>/

<root>/dev/sda1</root>/

<cmdline> ro</cmdline>/

</os>/

<memory>524288</memory>/

<vcpu>1</vcpu>/

<devices>/

<disk type='file'>/

<source file='/var/lib/xen/images/root'/>/

<target dev='sda1'/>/

</disk>/

<interface type='bridge'>/

<source bridge='xenbr0'/>/

<mac address='d0:0d:52:C5:09:3E'/>/

</interface>/

</devices>/

</domain>";

dom=virDomainDefineXML(conn,xmlconfig);

if (!dom)

{

fprintf(stderr, "Domain definition failed");

return 1;

}

if (virDomainCreate(dom) < 0)

{

virDomainFree(dom);

fprintf(stderr, "Cannot boot guest");

return 1;

}

fprintf(stderr, "Guest %s has booted/n", virDomainGetName(dom));

virDomainFree(dom);

return 0;

}

这个文件启动的虚拟机的镜像文件来自eucalyptus推荐的IMG，放在/var/lib/xen/images/root

这里为了方便，省去了两个空白文件，太大了而且是空文件，所以没考过来

编译服务器代码生成.so文件

gcc -g -fPIC -shared -olibeucalyptusNC.so -I $AXIS2C_HOME/include/axis2-1.6.0/ -Isrc -L$AXIS2C_HOME/lib -laxutil -laxis2_axiom -laxis2_engine -laxis2_parser -lpthread -laxis2_http_sender -laxis2_http_receiver -lguththila -lvirt server/*.c

在axis2c的服务器文件夹下新建一个eucalyptusNC文件夹，并将生成的libeucalyptusNC.so和server.xml文件拷到这个文件夹下，然后启动服务器

生成客户端代码

sh WSDL2C.sh -uri eucalyptusNC.wsdl -g -ss -d adb -u -f -o client

将文件eucalyptusNC.c拷到client文件夹中

eucalyptusNC.c中代码如下

#include "axis2_stub_eucalyptusNC.h"

int main(int argc,char *argv)

{

axutil_env_t * env = NULL;

axis2_char_t * operation = NULL;

axis2_char_t * client_home = NULL;

axis2_char_t * endpoint_uri = NULL;

axis2_stub_t * stub = NULL;

adb_ncRunInstanceResponse_t* ref=NULL;

adb_ncRunInstance_t* sent=NULL;

char val[]="ncRunInstance";

char ref_val[20] ;

endpoint_uri = "http://10.51.3.88:9090/axis2/services/eucalyptusNC";

env = axutil_env_create_all("alltest.log", AXIS2_LOG_LEVEL_TRACE);

/* Set up deploy folder. */

client_home = AXIS2_GETENV("AXIS2C_HOME");

if (!client_home)

client_home = "../../../deploy";

stub=axis2_stub_create_eucalyptusNC(env,client_home,endpoint_uri);

sent=adb_ncRunInstance_create(env);

adb_ncRunInstance_set_cmd(sent,env,val);

int s=0;

ref= axis2_stub_op_eucalyptusNC_ncRunInstance(stub,env,sent);

if (!ref)

{

printf("Error: response NULL/n");

return -1;

}

printf("Result:%s /n", adb_ncRunInstanceResponse_get_result(ref, env));

return 0;

}

其中有一行endpoint_uri = "http://10.51.3.88:9090/axis2/services/eucalyptusNC";这行代表服务器的地址，设置这个可以设置服务器的地址

生成客户端可执行文件

gcc -o eucalyptusNC -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 client/*.c -ldl -Wl,--rpath -Wl,$AXIS2C_HOME/lib

配置好环境变量运行客户端

将上面列子嵌入到eclipse工程

将上面server和client文件更名为eucalyptusNC和eucalyptusNCClient拷贝到eclipse工程文件夹下

用eclipse工程文件生成libeucalyptusNC.so

1. 新建一个C动态库项目eucalyptusNC，如下：

2. 设置环境变量

将“axis2c的安装目录”/include/axis2-1.6.0

“axis2c的安装目录”/include/axis2-1.6.0/platforms

“axis2c的安装目录”/include/axis2-1.6.0/platforms/unix 包含进来

将“axis2c的安装目录”/lib包含到库中

3. 设置编译规则

在GCC C Compiler 选择下的Optimization栏右边添加-fPIC命令

在GCC C Linker command中添加gcc -laxutil -laxis2_axiom -laxis2_engine -laxis2_parser -lpthread -laxis2_http_sender -laxis2_http_receiver -lguththila -lvirt
