using postgresql driver in as7

oourfali Jun 28, 2011 9:35 AM

Hello,

I want to deploy the postgresql jdbc driver, so I downloaded a driver that supports jdbc4 from http://jdbc.postgresql.org/download.html

(the version I used is 9.0-801 JDBC 4 )

I added a datasource entry in standalone.xml, and also a driver entry there.

On startup, I get the following errors:

16:27:54,850 ERROR [org.jboss.as.server] Boot update failed: "Failed to load module for driver [org.postgresql.Driver]"

and afterwards:

16:27:58,353 INFO [org.jboss.as.server] (MSC service thread 1-1) Service status report

New missing/unsatisfied dependencies:

service jboss.jdbc-driver.____________________________ (missing) required by [service jboss.data-source.java:/DataSource]

I followed the manual in https://docs.jboss.org/author/display/AS7/How+do+I+migrate+my+application+from+AS5+or+AS6+to+AS7

and http://community.jboss.org/wiki/DataSourceConfigurationinAS7

in order to add that jdbc driver.

I made sure I have the META-INF/services/java.sql.Driver in the jar, and I put the jar in the deployments directory.

(Before trying version 9.0-801 I tried an older version that didn't contain the file above, so I used the manual to add the file, but it didn't help).

Are you familiar with some kind of problem with the postgresql driver with AS7?

A working postgresql-as7 configuration sample will be helpful.

Thank you,

Oved

I'm using PG 9.1beta2, and the driver 9.1 since 2 or 3 weeks. There are no problems. What did you exactly do:
a) Deployment of the driver or provisioning as a module?
b) What exactly are your modifications in standalone.xml?

I used provisioning.

I made the following modifications to standalone.xml:

under datasources:

	<datasource jndi-name="java:/DataSource" pool-name="DataSource" enabled="true" use-java-context="true">
	<connection-url>
	jdbc:postgresql://10.35.1.30:5432/db
	</connection-url>
	<driver-class>
	org.postgresql.Driver
	</driver-class>
	<driver>
	postgresql-9.0-801.jdbc4.jar
	</driver>
	<transaction-isolation>
	TRANSACTION_READ_COMMITTED
	</transaction-isolation>
	<pool>
	<min-pool-size>
	1
	</min-pool-size>
	<max-pool-size>
	100
	</max-pool-size>
	<prefill>
	true
	</prefill>
	<use-strict-min>
	false
	</use-strict-min>
	</pool>
	<security>
	<user-name>
	postgres
	</user-name>
	<password> password
	</password>
	</security>
	<validation>
	<validate-on-match>
	false
	</validate-on-match>
	<background-validation>
	false
	</background-validation>
	<useFastFail>
	false
	</useFastFail>
	</validation>
	<statement>
	<prepared-statement-cache-size>
	100
	</prepared-statement-cache-size>
	<share-prepared-statements/>
	</statement>
	</datasource>

and under drivers:

This is my module.xml:
      <?xml version="1.0" encoding="UTF-8"?>
      <module xmlns="urn:jboss:module:1.0" name="org.postgresql">
         <resources>
            <resource-root path="postgresql.jar"/>
         </resources>
         <dependencies>
            <module name="javax.api"/>
            <module name="javax.transaction.api"/>
         </dependencies>
      </module>
This is my datasource section
      <datasource jndi-name="java:/swe1DS" pool-name="swe1DS">
         <connection-url>jdbc:postgresql:jbossdb</connection-url>
         <driver>postgresql</driver>
         <security>
            <user-name>...</user-name>
            <password>...</password>
         </security>
         <pool>
            <min-pool-size>1</min-pool-size>
            <max-pool-size>4</max-pool-size>
         </pool>
         <validation>
           <check-valid-connection-sql>SELECT 1</check-valid-connection-sql>

         </validation>
      </datasource>
...
      <driver name="postgresql" module="org.postgresql">
         <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
      </driver>
I defined the XA datasource class because I also had problems before. I don't have the driver class declaration inside the datasource section.

As a module it indeed worked.

Thank you,
