JBoss中查找UserTransaction的JNDI问题，急啊！

[ccc426]

我在JBOSS下用到UserTransaction，但是总是在绑定JNDI时出错
我是需要进行什么配置吗？还是代码有问题，诸位大侠帮忙

代码：
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.transaction.UserTransaction;
import java.util.Hashtable;

import com.basic.vo.adm.RolesVO;
import com.bo.adm.RolesManager;

public class TestJTA2 {
public TestJTA2() {
}

private Context getInitialContext() throws Exception {
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
return new InitialContext(environment);
}

public void test() throws Exception {
Context context = getInitialContext();
UserTransaction ut = (UserTransaction) context.lookup("java:/comp/UserTransaction");
try {
ut.begin();
//操作数据
RolesVO roles = new RolesVO();
roles.setStaffID("pk");
roles.setAgentID("ag");
roles.setName("tt");
RolesManager.getInstance().registerRoles(roles);
ut.commit();
} catch (Exception ex) {
try {
ut.rollback();
} catch (Exception syex) {
throw new Exception
("Rollback failed: " + syex.getMessage());
}
throw new Exception
("Transaction failed: " + ex.getMessage());
}

}

public static void main(String[] args) {
TestJTA2 testjta2 = new TestJTA2();
try {
testjta2.test();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}

错误：
javax.naming.NameNotFoundException: comp not bound

不懂
帮您顶下先

[jFresH_MaN]

你使用的JNDI name是tomcat的
呵呵
应该是

UserTransaction ut = (UserTransaction) context.lookup("java:/UserTransaction");

[jFresH_MaN]

你应该配置了UserTransaction
javax.transaction.UserTransaction作为JNDI那么
lookup的时候应该使用
java:/JNDIName即java:/UserTransaction

[飞行的兔子]

Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
prop.put(Context.PROVIDER_URL, "localhost:1099");
prop.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
是这样写,没错,楼主将jndi 目录空间搞错了
jboss: java:/defaultDs

tomcat: java:comp/env/defaultDs
这是两个服务器的默认jndi空间名称!
如果楼主用comp/UserTransaction这个作为绑定名称,也可用comp/UserTransaction作为查找名称啊!

谢谢楼上两位，通过！
