Alfresco with CMIS 1.0 some time error Resource leaked

[phong_van]

Hi everyone,

I'm using Alfresco 5.2 - community version with cmis on Java 8. Recently, on log file some time miss error:

I've check CPU, RAM, DISK on Alfresco server, everything still good. So someone can give me some help?

Are you including Basic Auth credentials in your invocation?

[phong_van]

Yes,

This is my code 

private void configureSessionFactory()
{
if (sessionFactory == null)
{
this.parameters = new HashMap<String, String>();

// user credentials
parameters.put(SessionParameter.USER, username);
parameters.put(SessionParameter.PASSWORD, password);

// connection settings
parameters.put(SessionParameter.ATOMPUB_URL, repoUrl);
parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

// Create session factory
this.sessionFactory = (SessionFactoryImpl) SessionFactoryImpl.newInstance();
}
}


private void getRepository()
{
configureSessionFactory();
List<Repository> repositories = sessionFactory.getRepositories(parameters);
this.repository = repositories.get(0);
}

public Session createSession() throws Exception
{
log.debug("try to create session");
if (repository == null)
{
throw new RepositoryUnavailableException(lastException);
}
return repository.createSession();
}

You can try to create the session just after getting the repository reference:

Dear Angel Borroy,

Thanks for your reply. You mean that I have to change my code from:

parameters.put(SessionParameter.ATOMPUB_URL, atompubUrl);
parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

To 

parameters.put(SessionParameter.BROWSER_URL, browserUrl);
parameters.put(SessionParameter.BINDING_TYPE, BindingType.BROWSER.value());

And, other question, which binding type (BROWSER, ATOMPUB) is better about performance?

Once again, many thanks your help.
