Thank you for the answer.
I learned some concept about JNDI.
Here is what I'v got, please help me to confirm.
for example, I config a datasource in TomEE
<Resource id="jdbc/test1" type="DataSource">
JdbcDriver oracle.jdbc.xa.client.OracleXADataSource
JdbcUrl jdbc:oracle:thin:@localhost:1521:xe
UserName test
Password test
JtaManaged true
</Resource>
And In WEB-INF/web.xml
<resource-ref>
<description>DataSource</description>
<res-ref-name>jdbc/test2</res-ref-name>
<res-type>javax.sql.XADataSource</res-type>
<res-auth>Container</res-auth>
<mapped-name>jdbc/test1</mapped-name>
</resource-ref>
1. "jdbc/test1" is a product sepecific name or global jndi name?
2. "jdbc/test2" is a local jndi name, it is in "java:comp/env".
When I use @Resource to inject this resource.
(in fact, I defined two datasources in tomee.xml, and this is the second
one, to avoid tomee maps the first datasource in tomee.xml when there is no
comfortable mapping.)
@Resource(name="jdbc/test1") OK,(WHY?)
@Resource(name="jdbc/test2") OK, (I can understand)
@Resource(mappedname="jdbc/test1") OK, (I can understand)
@Resource(mappedname="jdbc/test2") NOK, (I can understand)
@Resource(lookup="XXXX") Nerver OK..I don't know what should be here.
the lookup API says
"The name of the resource that the reference points to. It can link to any
compatible resource using the global JNDI names. "
I got confused,
what is the product specific, global jndi namespace?
and what portable string means? it means local JNDI name?
please help me. thanks.
