ovirt-engine-sdk-java的使⽤过程中的错误整理本篇记录ovirt java sdk的使⽤前准备与使⽤中的⼀些坑。
0、参考⽂档：
java下载过程1、下载ovirt java sdk的jar包
2、下载ine.sdk所需要的依赖包
在ing.sdk下载页⾯下⽅，有着⼀个“Compile Dependencies”表格，是sdk的依赖包。
根据表格中的信息下载相应的版本的jar包。
3、测试使⽤ine.sdk
import ine.sdk.Api;aspenv9
import ptions.ServerException;
import ptions.UnsecuredConnectionAttemptError;
import java.io.IOException;
import java.security.KeyManagementException;
import java.util.List;
public class SdkTest {
private static final String URL = "host/api/";
private static final String USERNAME = "123@hao";        // 普通⽤户账号
private static final String PASSWORD = "123456";
@SuppressWarnings("deprecation")
public static void main(String[] args) throws ClientProtocolException, ServerException,

Api api = new Api(URL, USERNAME, PASSWORD);
List<VM> vm = VMs().list();
int len = vm.size();
for (int i = 0; i < len; i ++) {
System.out.printf("%s\n", vm.get(i).getName());
}
try {
api.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
* 注意：“ClientProtocolException”异常是Api类必须的，⽽且是在org.apache.http.client.ClientProtocolException（httpclient 4.2）中。
4、不停的ClassNotFoundException
（1）照理来说，只要将这些jar包放⼊buildpath中，就可以正常使⽤sdk了，但是实际的运⾏结果：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/params/HttpParams
at ine.sdk.Api.<init>(Api.java:596)
at ine.sdk.Api.<init>(Api.java:109)
at SdkTest.main(SdkTest.java:22)
Caused by: java.lang.ClassNotFoundException: org.apache.http.params.HttpParams

at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 3 more
显⽰缺少了org.apache.http.params.HttpParams，但是我并没有⽤到这个东西！？
org.apache.http.params.HttpParams ----->>> httpcore-4.2.jar
（2）加⼊了httpcore之后，还没完：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

这次缺的是org.apachemons.logging.LogFactory。有种没完没了的感觉。
org.apachemons.logging.LogFactory ----->>> commons-logging-1.2.jar
（3）⼜加了jar包，再次运⾏程序：
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/codec/binary/Base64

是真的没完没了！？⼜缺了包！这次是dec.binary.Base64。到底是哪⾥⽤到了这东西dec.binary.Base64 ----->>> commons-codec-1.10.jar
5、创建Api代理过程中的错误
（1）执⾏上⾯的代码，没有ClassNotFoundException。但是出现了500服务器错误。
Exception in thread "main"
code  : 500
reason: Internal Server Error
detail: <html><head><title>Error</title></head><body>Internal Server Error</body></html>

不知道具体原因。代码中使⽤的是普通账号，但是该账号和密码在ovirt engine上能成功登录。
后来使⽤管理员账号登录绕过了这个问题。
（2）管理员账号登录失败，因为证书验证失败
Exception in thread "main" javax.ssl.SSLPeerUnverifiedException: peer not authenticated

武汉java培训机构在这⾥采⽤的解决⽅法是将ovirt engine的证书添加到jre的证书库中。
⾸先将下载好的crt证书复制到jre的安装⽬录下的bin⽬录中。
然后，在bin⽬录下打开cmd，执⾏命令：
D:\Software\Java\jre1.8\bin>keytool -import -v -trustcacerts -alias svcloud - -storepass changeit -keystore D:/Software/Java/jre1.8/lib/sec
urity/cacerts
