MyBatis-Guice multiple datasource configuration does not work with JNDI datasources #799

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Is it expected that JNDI datasources should work using the Multiple Datasources 
configuration advice given at
  http://mybatis.github.com/guice/core.html
??

We spent a great deal of time reading doc and forums - both before and after we 
encountered the problem described below - but could find nothing related.

We needed to add an additional datasource to the application that has been 
running fine with a single JNDI connection configured using the MyBatisModule 
directly.

When we used a PrivateModule to wrap each of our MyBatisModules for the two 
datasources we get the message:
  null returned by binding at org.mybatis.guice.MyBatisModule.bindDataSourceProviderType(MyBatisModule.java:215) ... while locating javax.sql.DataSource

After tracing and checking for hours, we finally got this to work by using 
direct JDBC with the PooledDataSourceProvider.class. 

I've attached three files:
 - the log from Tomcat showing the detailed exceptions we get.
 - The AppListener module configured with JNDI that fails.
 - The AppListener module configured with direct JDBC

The two modules are identical except for the lines I've commented out by each. 
A quick diff will show.

Thank you.

Are you looking to work with the rules of JNDI in Tomcat?
http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html
Does the example in section "Using resources"?

Error stack shows that failed to get JNDI resource.
