[jboss-user] [JCA/JBoss] - No suitable driver found for java:PostgresDS

Hello all, First of all, this is my first post and I would like to thank anyone that has interest in helping me. That's the way communities grown. Below follows my development environment configuration: * Java 6 Update 3; * JBoss 4.2.2 GA; * PostgreSQL 8.2; I am trying to run a very simple example in order to check if I correctly configured a PostgreSQL datasource, but I'm receiving an error message: javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for java:PostgresDS" I have done the following steps in order to configure the PostgreSQL datasource: 1. Included a postgres-ds.xml in the [JBOSS_HOME]/server/default/deploy directory, with the follwing content: <local-tx-datasource> <jndi-name>PostgresDS</jndi-name> <connection-url>jdbc:postgresql://localhost:5432/jboss</connection-url> <driver-class>org.postgresql.Driver</driver-class> <user-name>jboss</user-name> jboss <!-- sql to call when connection is created. Can be anything, select 1 is valid for PostgreSQL <new-connection-sql>select 1</new-connection-sql> --> <!-- sql to call on an existing pooled connection when it is obtained from pool. Can be anything, select 1 is valid for PostgreSQL <check-valid-connection-sql>select 1</check-valid-connection-sql> --> <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml --> <type-mapping>PostgreSQL 8.0</type-mapping> </local-tx-datasource> 2. Included the postgresql-8.2-506.jdbc4.jar file in the [JBOSS_HOME]/server/default/lib directory. 3. Create the needed database (jboss) and the needed username and password combination (jboss/jboss). I am trying to connect to the PostgresSQL database with the following line of code inside a JSP page: <sql:setDataSource dataSource="java:PostgresDS" /> I have already changed the dataSource propertu value to "PostgresDS", "java:/PostgresDS", and received the same error. Please, any help is appreciated! Thank you for reading, André View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4107706#...
