In some cases, it is caused by the datasource not in the same target with your servers. The servers that are using the datasource should be added to the same targets.

blocks|key|450622|text|可能听起来很蠢，但既然发生在我身上，我会分享的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|450623|当您在Weblogic下创建数据源时(至少10.3.4)，不要忘记完成整个配置过程(在结束之前启用了Finish按钮)。|offset|length|style|CODE|450624|在最后一页中，您将能够为服务器activate数据源，而不仅仅是创建它。|450625|要检查您的DB是否已启动，您可以查看服务器的JNDI树。|450626|entityMap^0|0|1E|6|0|F|8|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@$D|S|E|T|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|U|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|M|$]]

May sound stupid, but since it happened to me I'll share it.

When you create the datasource under Weblogic (at least 10.3.4), don't forget to go through the whole configuration process (The <code>Finish</code> button is enabled before the end).

On this very last page, you'll be able to <code>activate</code> the datasource for a server, not only create it.

To check if your DB is up you can look the JNDI tree of the server.

I've faced the same problem. My application is connecting to a Oracle DB that runs on a local Oracle Sql Server (Oracle XE 11g). From other answers I've seen that deleting the Weblogic cache /tmp, /cache and even /logs might work. My problem was that the local service Oracle Service XE was STOPPED. I know it's silly but it might help. So you should do this 3 things: 
- clear cache; 
- check if the DB server service is running; 
- try restarting the WEBLOGIC server;
Those things above worked for me.

blocks|key|1337383|text|java是资源的根JNDI命名空间。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1337384|所以也许你需要|1337385|dataSource+=+(javax.sql.DataSource)+context.lookup("java:jdbc/testDatasource");|code-block|syntax|javascript|1337386|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

java is the root JNDI namespace for resources. 

So maybe you need

<pre><code>dataSource = (javax.sql.DataSource) context.lookup("java:jdbc/testDatasource");
</code></pre>

blocks|key|2479668|text|当我们在weblogic中的两个数据源中定义了相同的JNDI名称(我创建了两个用于测试Datasource不同属性的JNDI名称)时，也会发生此错误。我不得不删除其中一个，效果很好。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2479669|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I faced the same issue and it's fixed now :)

The fix is,

<pre><code> String DATASOURCE_CONTEXT = prop.getProperty("tcDataSourceContext");
 log("DATASOURCE_CONTEXT.."+DATASOURCE_CONTEXT);
 Properties env = new Properties( ); 
 env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); 
 env.put(Context.PROVIDER_URL,"t3://abc.com:8001");
 Context initialContext = new InitialContext(env);
 DataSource datasource = (DataSource)initialContext.lookup(DATASOURCE_CONTEXT);
 if (datasource != null) {
 conn = datasource.getConnection();
 }
 else{
 log("Failed to lookup datasource.");
 } 
</code></pre>

1#. abc.com is the server URL where WebLogic is deployed.
2#. 8001 is the port number where WebLogic Admin server is listening.

3#. Make sure the below is configured correctly.

Wrong one:
tcDataSourceContext=java:comp/env/jdbc/datasourcename

Correct one:
tcDataSourceContext=jdbc/datasourcename

4#. Also, go to WebLogic server and navigate to /Oracle/Middleware/wlserver_10.3/server/lib/ and execute the below command.

Command:
java -jar wljarbuilder.jar -profile wlfullclient5

The above command creates a jar file with all the jar's inside WebLogic server /lib folder and place it in your client java code build path and server/lib folder as well.

Hope this helps! Kindly let me know if you have any issues.

blocks|key|1337650|text|在我的情况下，这是由于数据源在部署期间被销毁。解决方案是添加destroyMethod="“|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1337651|@Bean(name+=+"dataSource",+destroyMethod="")

In my case, it was due to the datasource was being destroyed during deployment. The solution is to add destroyMethod=""

It appeard that password was wrong, this won't necessery be your case, as the first exception is generic and may have different causes, some were already explained the previous answers, so I am just adding mine.

Fixing password and testing the db connection gave then :
