Hi all!
JBOSS,datasource jndi?datasource's config should be correct!But In the init()
mothod of HttpServlet's instance I could not lookup datasource.
env:
jboss3.26+linux+jdk1.4.2?DB:oracle9i
I met with a little matter in my project.
When I init the data in my startup-servlet,I can't lookup the datasource.
Datasource's config should be correct! I'm reffering to
'example/jca/oracle_ds.xml'
Thus once the web-app has deployed,it is normal for accessing the datasource!
I'm worried and indignant.
Maybe some config was missing or wrong! Help me! thank u very very very much!
1?config datasource:
<!--test_oracle_ds.xml-->
<local-tx-datasource>
<jndi-name>jdbc/test</jndi-name>
....
ps:config in web.xml and jboss-web.xml
<!--web.xml-->
<resource-ref>
DB Connection
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
==============================
<!--jboss-web.xml-->
<jboss-web>
<resource-ref>
<res-ref-name>jdbc/test</res-ref-name>
<jndi-name>java:/jdbc/test</jndi-name>
</resource-ref>
</jboss-web>
2?java code
StartupServlet.java:
init(..)
Context init = new javax.naming.InitialContext();
ctx = (Context) init.lookup("java:comp/env");
DataSource ds = (DataSource)ctx.lookup("jdbc/test");
or Context ctx = new javax.naming.InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/jdbc/test");
or Context ctx = new javax.naming.InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/test");
All of this are fail,they give me the info: datasource no bound
more info ?"javax.naming.NamingException: Could not dereference object [Root
exception is javax.naming.NameNotFoundException: jdbc not bound]"
jdbc not bound: this jdbc must be refer to the "jdbc" of
"<jndi-name>jdbc/test</jndi-name>",
as I have tested "<jndi-name>test</jndi-name>", then give me info- "test not
bound".
The rather that when I read the log,I find the datasource has been bound to
"java:/jdbc/test".
The state of datasource must be valid.
........
mbeans:
jboss.jca:service=LocalTxCM,name=jdbc/test state: Registered
jboss.jca:service=ManagedConnectionPool,name=jdbc/test state: Started
jboss.jca:service=ManagedConnectionFactory,name=jdbc/test state: Started
.....
.......
[org.jboss.web.tomcat.tc5.TomcatDeployer] Linking 'jdbc/test' to JNDI name:
java:/jdbc/test
Thus once the web-app has deployed,it is normal for accessing the datasource!
I'm worried and indignant.
The relative oracle jar(ojdbc14.jar) has been copied into "...server/all/lib".
I greatly appreciate your timely help.
