Spring boot JNDI datasource lookup failure - Name comp/env/jdbc not found in context “java:”

Question

I have setup a spring boot (v 1.1.9) application to deploy as a WAR file. And I\'m trying to integrate this web application with an existing data service module (added as a

Answer 1

I am able to connect my Spring-Boot application (deployed in Websphere Application Server 9) to WAS datasource. The following code worked for me, for connecting to DataSource:

@Bean(name = "WASDataSource")
public DataSource WASDataSource() throws Exception {        
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
return dataSourceLookup.getDataSource("DSNAME");
}   

@Bean(name = "WASDataSourceJdbcTemplate")
public JdbcTemplate jdbcTemplate_WASDS(@Qualifier("WASDataSource")
DataSource dsDB2) {
return new JdbcTemplate(dsDB2);
}

Note: The name of Datasource "DSNAME" is the name which appears on the UI of Websphere console. You can see that via -> Select Resources > JDBC > Data Sources.

Then I created jdbc template:

@Autowired
@Qualifier("WASDataSourceJdbcTemplate")
private JdbcTemplate db2WASTemplate;`

And running query using the query method works fine :
db2WASTemplate.query()

I did not create any Web.xml or ibm-web-bnd.xml files

Answer 2

You need to have resource reference with jdbc/fileUploadDS name in your web.xml. And make sure it is bound to actual datasource name during installation or via ibm-web-bnd.xml file.

Definition in web.xml:

<resource-ref>
    <description />
    <res-ref-name>jdbc/fileUploadDS</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

If you dont want to use web.xml, then in normal Java EE app you could just add in web component (servlet, filter) the following class annotation:

@Resource(name="jdbc/fileUploadDS", type=javax.sql.DataSource.class, lookup="jdbc/fileUploadDS")

but I'm not Spring-boot expert, so don't know, if it will work or is possible there.

Answer 3

I am facing the same problem. I don't know how to define tag in spring boot since there is no web.xml file in the spring boot.

So far what I came to know that we have to define it in the application file from where we start our spring application. I think we need to use this method to set the Datasource:

  @Bean(destroyMethod="")
  @ConfigurationProperties(prefix="datasource.mine")
  public DataSource dataSource() throws Exception {
      JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
      return dataSourceLookup.getDataSource("java:jdbc/configurationFile");
  }

Answer 4

I just configured spring boot with my custom datasource as follows:

@Bean
@ConfigurationProperties("spring.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

and inside the application.properties file I defined all datasource settings as usual

spring.datasource.driver-class-name= ***
spring.datasource.url= ***
spring.datasource.username= ***
spring.datasource.password= ***
spring.datasource.jndi-name=jdbc/myDB

It works no nicely with @SpringBootApplication with all other default settings

Thanks
