Re: can't seem to access ClientRepository from Servlet
I did get access to a remote RMI repository working in my web application
using the following. This is a duplicate details that I put in my
other reply.
```java
public class MyRepositoryFactory implements ObjectFactory {
public Object getObjectInstance(Object obj,
Name name2, Context nameCtx, Hashtable environment)
throws NamingException {
// Acquire an instance of our specified bean class
Repository repository = null;
String location = new String();
// Customize the bean properties from our attributes
Reference ref = (Reference) obj;
Enumeration addrs = ref.getAll();
while (addrs.hasMoreElements()) {
RefAddr addr = (RefAddr) addrs.nextElement();
String name = addr.getType();
String value = (String) addr.getContent();
if (name.equals("url")) {
try {
repository = new URLRemoteRepository(value);
} catch (MalformedURLException e) {
throw new NamingException("Invalid 'url' value " + value);
}
}
}
// Return the customized instance
return (repository);
}
}
```
```java
public class SessionFactory {
public static Session getSession() throws RepositoryException, NamingException {
//org.apache.jackrabbit.rmi.client.ClientRepositoryFactory a;
Context initial = new InitialContext();
Context context = (Context) initial.lookup("java:comp/env");
Repository repository = (Repository) context.lookup("jcr/Repository");
Session session = repository.login(
new SimpleCredentials("admin", "admin".toCharArray()));
return session;
}
}
```
context.xml placed in META-INF folder
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- The contents of this file will be loaded for each web application -->
<Context path="/jcrweb07/" >
<Resource name="jcr/Repository" auth="Container"
type="javax.jcr.Repository"
factory="gov.ca.brea.jcrweb07.MyRepositoryFactory"
url="http://localhost:8081/rmi"/>
</Context>
```
