Hi all,
I've searched everywhere for errors similar to mine, but I didn't find anything. I
think I can assume that I'm doing something completely wrong :-P
I am trying to have a web application use a datasource.
I'm using mySQL. I configured the datasource with this file mysql-ds.xml file:
<?xml version="1.0" encoding="UTF-8"?>
| <datasources>
| <local-tx-datasource>
| <jndi-name>springCsm</jndi-name>
|
<connection-url>jdbc:mysql://localhost:3306/spring_csm</connection-url>
| <driver-class>com.mysql.jdbc.Driver</driver-class>
| <user-name>root</user-name>
| <password>root</password>
|
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
| <metadata>
| <type-mapping>mySQL</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
Then I have the web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
| <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID"
version="2.5">
| <display-name>SpringCSM-ws</display-name>
| <servlet>
| <servlet-name>TestWs</servlet-name>
| <servlet-class>com.osdp.csm.test.TestWs</servlet-class>
| <load-on-startup>1</load-on-startup>
| </servlet>
| <servlet-mapping>
| <servlet-name>TestWs</servlet-name>
| <url-pattern>/TestWs</url-pattern>
| </servlet-mapping>
| <session-config>
| <session-timeout>30</session-timeout>
| </session-config>
|
| <resource-ref>
| <description>DB Connection</description>
| <res-ref-name>springCsm</res-ref-name>
| <res-type>javax.sql.DataSource</res-type>
| <res-auth>Container</res-auth>
| </resource-ref>
|
| <welcome-file-list>
| <welcome-file>index.html</welcome-file>
| <welcome-file>index.htm</welcome-file>
| <welcome-file>index.jsp</welcome-file>
| <welcome-file>default.html</welcome-file>
| <welcome-file>default.htm</welcome-file>
| <welcome-file>default.jsp</welcome-file>
| </welcome-file-list>
| </web-app>
and the jboss-web.xml file:
<jboss-web>
| <resource-ref>
| <res-ref-name>springCsm</res-ref-name>
| <jndi-name>java:comp/env/springCsm</jndi-name>
| </resource-ref>
| </jboss-web>
In my client, I lookup the datasource with the following code:
| @WebMethod
| public String greet( @WebParam(name = "name")
| String name )
| {
| Context ctx;
| try {
| ctx = new InitialContext();
| Context envContext = (Context) ctx.lookup("java:comp/env");
| DataSource ds = (DataSource) envContext.lookup("springCsm");
| Connection conn = ds.getConnection();
|
| } catch (Throwable e) {
| throw new RuntimeException(e);
| }
| return "OK";
| }
What I get is this nasty exception:

The last five lines are repeating recursively many times.
I have tried with many different little changes, but what I get is always this kind of
error. Since I'm completely a newbie I think there're something importat I'm
missing, but I don't know exactly what...any clue?
Regards,
GiP
