Hello,
I am trying to use CMIS query to retrieve list of folders in the repository using the following code:

query = "SELECT cmis:path, cmis:name, cmis:objectId, cmis:creationDate, cmis:lastModificationDate FROM cmis:folder";
ItemIterable<QueryResult> rows = m_session.query(query, false);

for (QueryResult row : rows)
{
    List<PropertyData<?>> properties = row.getProperties();

    for (PropertyData<?> property : properties)
    {
          ……
    }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Sometimes, it throws this exception:

I use the following code for create session:

// default factory implementation
SessionFactory factory = SessionFactoryImpl.newInstance();
Map<String, String> parameter = new HashMap<String, String>();

// connection settings
parameter.put(SessionParameter.ATOMPUB_URL, "https://api.alfresco.com/cmis/versions/1.0/atom");
parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
parameter.put(SessionParameter.AUTH_HTTP_BASIC, "false");
parameter.put(SessionParameter.HEADER + ".0", "Authorization: Bearer " + accessToken);
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");

List<Repository> repositories = factory.getRepositories(parameter);
session = repositories.get(0).createSession();
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks.

Were you able to figure out the problem behind this? I am facing a similar issue. Exception below.

I tried changing the alfresco tomcat's Connector configuration to increase connectionTimeout but it did not seem to help.

File: /home/alfresco/alfresco-4.0.e/p_alf_svc1/conf/ server.xml

    <Connector port="8080" URIEncoding="UTF-8" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" address="10.3.4.84" />
‍‍‍‍‍

Any other pointers/help?

In your previous post you said your alfresco port is 8080,but the url you pasted did not contain the port part.
And make sure you provided the correct atom url

http://localhost:8080/alfresco/cmisatom for cmis version 1.0
http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom for cmis version 1.1
‍‍‍‍

You can paste your code here.

amit_kapps

port 8080 does not show up on the URL since the requests are handled by apache.
the error "Unexpected end of file from server" only happens sporadically.

I'm using the below 2 cmis client libraries. I believe they are cmis version 1.0. How do I know if I need to use cmis 1.0 or 1.1 url?:

<groupId>org.apache.chemistry.opencmis</groupId>
<artifactId>chemistry-opencmis-client-impl</artifactId>
<version>0.7.0</version>

         
<groupId>org.alfresco.cmis.client</groupId>
<artifactId>alfresco-opencmis-extension</artifactId>
<version>0.3</version>

‍‍‍‍‍‍‍‍‍‍‍

kaynezhang

Have you tried to send request to alfresco server directly ?
Which url you are using depends on whether you want to use features in cmis specification 1.1.
I sugest you use 1.1 url.
