I did this:
context.mxl
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/mavenproject3">
<Realm className="realm.test.MyDataSourceRealm"
dataSourceName="MyDataSource"
userTable="usertable"
userNameCol="usercol"
userCredCol="passcol"
userRoleTable="roltable"
roleNameCol="rolcol"/>
</Context>
MyDataSourceRealm.java:
package realm.test;
import java.sql.Connection;
import javax.naming.InitialContext;
import javax.sql.DataSource;
public class MyDataSourceRealm extends
org.apache.catalina.realm.DataSourceRealm{
@Override
protected Connection open() {
DataSource dataSource = null;
try{
dataSource = (DataSource)new
InitialContext().lookup("java:openejb/Resource/" + dataSourceName);
return dataSource.getConnection();
}
catch(Exception e){
e.printStackTrace();
}
return null;
}
}
And i always get ClassNotFoundException:
Severe: Begin event threw exception
java.lang.ClassNotFoundException: realm.test.KxDataSourceRealm
My class is in my same project, and the package is correct, i dont know why
my class cannot be found.
What can be??
Thanks
