Question

I am building a project using “Maven”.
In the Pom.xml i have added dependency for Postgresql and it is downloaded (as required) and is present in the Project’s libs/ folder.

Now i have made a connection to it in my java file as follows :

static String userid="postgres", password = "myPassword";
static String url = "jdbc:postgresql:coredb_jfeed6";
static Connection con;
con = DriverManager.getConnection(url,userid, password);

Where “coredb_jfeed6” is my database name.

There is no compile time error. But at runtime it produces the following error :

   Exception stack is:
    1. No suitable driver found for jdbc:postgresql:coredb_jfeed6 (java.sql.SQLException)
    java.sql.DriverManager:640 (null)
    Could not get JDBC Connection; nested exception is java.sql.SQLException: No suitable driver found for jdbc:postgresql:coredb_jfeed6
    (org.springframework.jdbc.CannotGetJdbcConnectionException)
    org.springframework.jdbc.datasource.DataSourceUtils:80 (null)

Root Exception stack trace:
java.sql.SQLException: No suitable driver found for jdbc:postgresql:coredb_jfeed6
    at java.sql.DriverManager.getConnection(DriverManager.java:640)
    at java.sql.DriverManager.getConnection(DriverManager.java:169)
    at org.springframework.jdbc.datasource.DriverManagerDataSource.getConnectionFromDriverManager(DriverManagerDataSource.java:173)

Could anyone please help me regarding this.?

Answer 1

Ok. I figured it out.

Its a BUG in Mule 3.1.2.

Its like “When an external library is to be searched, then Mule looks it in projects/lib folder. But this does not hold true for All the Database related Libraries like postgresql library” . So we need to put it in mule/user/lib folder for it to Work Correctly.
