CMIS getRepositories exception - Cannot access WSDL: http://******/alfresco/cmis/RepositoryService

[mikerawlins]

We're developing a new client application using CMIS and Alfresco. (Sorry - don't have access to server logs or even know what version we're running - set up by a different group).

My code works fine with using the Atom Pub binding, but we are having a lot of performance problems. In poking around I came across one article where a user said he got a 50% performance improvement using a web services binding instead of Atom Pub. So I decided to try it. Here's a relevant code snippet (URL masked)

                // Web Services binding - test for performance                String webservicesUrl = "http://******/alfresco/cmis";                final String BINDING_TYPE = BindingType.WEBSERVICES.value();                parameter.put(SessionParameter.BINDING_TYPE, BINDING_TYPE);                parameter.put(SessionParameter.WEBSERVICES_ACL_SERVICE, webservicesUrl + "/ACLService");                parameter.put(SessionParameter.WEBSERVICES_DISCOVERY_SERVICE, webservicesUrl + "/DiscoveryService");                parameter.put(SessionParameter.WEBSERVICES_MULTIFILING_SERVICE, webservicesUrl + "/MultiFilingService");                parameter.put(SessionParameter.WEBSERVICES_NAVIGATION_SERVICE, webservicesUrl + "/NavigationService");                parameter.put(SessionParameter.WEBSERVICES_OBJECT_SERVICE, webservicesUrl + "/ObjectService");                parameter.put(SessionParameter.WEBSERVICES_POLICY_SERVICE, webservicesUrl + "/PolicyService");                parameter.put(SessionParameter.WEBSERVICES_RELATIONSHIP_SERVICE, webservicesUrl + "/RelationshipService");                parameter.put(SessionParameter.WEBSERVICES_REPOSITORY_SERVICE, webservicesUrl + "/RepositoryService");                parameter.put(SessionParameter.WEBSERVICES_VERSIONING_SERVICE, webservicesUrl + "/VersioningService");                SessionFactory factory = SessionFactoryImpl.newInstance();                List<Repository> repositories = factory.getRepositories(parameter);                m_session = repositories.get(0).createSession();‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

getRepositories worked fine with Atom Pub, but I get an exception using the above code. cmisBaseException.getErrorContent() returns (URL masked):

Edited - I did figure out how to get info from the repository:

<blockcode>
         <cmisroductName>Alfresco Repository (Enterprise)</cmisroductName>
         <cmisroductVersion>4.1.3 (97)</cmisroductVersion>
</blockcode>



Any ideas?

Thanks,

RepositoryService's wsdl address is

http://localhost:8080/alfresco/cmisws/cmis/RepositoryService?wsdl‍

,you should appedn the "?wsdl" to it.
It is the same with other services wsdl.

[mikerawlins]

From CMIS workbench I tried connecting to URL

http://XXX.XX.XX/alfresco/cmisws/cmis/RepositoryService?wsdl

I get:

Exception: CmisConnectionException Cannot access WSDL: http://XXX.XX.XX.XX/alfresco/cmisws/cmis/RepositoryService?wsdl

  Check the URL, the binding, and the credentials.

The login credentials are correct.

I also tried specifying port 8080. I get a slightly different exception, but it also doesn't work.

Ideas?

For me on enterprise 4.1 the URL to use is

http://localhost:8080/alfresco/cmisws/RepositoryService?wsdl

That works as the URL in chemistry cmis workbench too.

[mikerawlins]

mrogers - Thanks!

Incremental progress - I can connect to the server from CMIS workbench using that form of URL the web services binding. When using it in my application I get an exception. Here's the code:

<java>
        try {
            if (m_session == null) {
                Map<String, String> parameter = new HashMap<String, String>();
                // Can also try org.apache.chemistry.opencmis.client.runtime.repository.ObjectFactoryImpl
                final String FACTORY_CLASS = "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl";
                parameter.put(SessionParameter.USER, userName);
                parameter.put(SessionParameter.PASSWORD, password);
                final String BINDING_TYPE = BindingType.WEBSERVICES.value();
                parameter.put(SessionParameter.BINDING_TYPE, BINDING_TYPE);


                // from      http://chemistry.apache.org/java/examples/example-create-session.html
                parameter.put(SessionParameter.WEBSERVICES_ACL_SERVICE, webservicesUrl + "/ACLService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_DISCOVERY_SERVICE, webservicesUrl + "/DiscoveryService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_MULTIFILING_SERVICE, webservicesUrl + "/MultiFilingService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_NAVIGATION_SERVICE, webservicesUrl + "/NavigationService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_OBJECT_SERVICE, webservicesUrl + "/ObjectService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_POLICY_SERVICE, webservicesUrl + "/PolicyService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_RELATIONSHIP_SERVICE, webservicesUrl + "/RelationshipService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_REPOSITORY_SERVICE, webservicesUrl + "/RepositoryService?wsdl");
                parameter.put(SessionParameter.WEBSERVICES_VERSIONING_SERVICE, webservicesUrl + "/VersioningService?wsdl");
                // parameter.put(SessionParameter.REPOSITORY_ID, "Main Repository");
                /*
                    <cmis:repositoryId>3d4aca1d-ac30-46e8-ae2c-26bae0b0629b</cmis:repositoryId>
                    <cmis:repositoryName>Main Repository</cmis:repositoryName>
                 */

                SessionFactory factory = SessionFactoryImpl.newInstance();
                List<Repository> repositories = factory.getRepositories(parameter);
                m_session = repositories.get(0).createSession();
            }
        }
</java>

And the exception in the getRepositories call:

Exception in thread "main" java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V   at org.apache.chemistry.opencmis.commons.impl.XMLUtils.newDocumentBuilder(XMLUtils.java:306)   at org.apache.chemistry.opencmis.commons.impl.XMLUtils.parseDomDocument(XMLUtils.java:332)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.getEndpointUrlFromWsdl(AbstractPortProvider.java:574)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.initServiceObject(AbstractPortProvider.java:500)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.getPortObject(AbstractPortProvider.java:454)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.getRepositoryServicePort(AbstractPortProvider.java:280)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.RepositoryServiceImpl.getRepositoryInfos(RepositoryServiceImpl.java:69)   at org.apache.chemistry.opencmis.client.bindings.impl.RepositoryServiceImpl.getRepositoryInfos(RepositoryServiceImpl.java:85)   at org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl.getRepositories(SessionFactoryImpl.java:109)   at org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl.getRepositories(SessionFactoryImpl.java:96)   at com.harbinger.mek.vm.repository.alfresco.AlfrescoRepositoryHelperImpl.repositoryLoginWS(AlfrescoRepositoryHelperImpl.java:226)   at com.harbinger.mek.vm.repository.alfresco.ECMRepositoryTestHarness.main(ECMRepositoryTestHarness.java:45)Disconnected from the target VM, address: '127.0.0.1:62695', transport: 'socket'‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I can see that my repository supports WSDL, so the problem is in my code. I don't see what's wrong with the code. The credentials are OK, and the webservicesUrl getting passed to the method is in the form:

http://XXXXXX.XXX.XXX.net/alfresco/cmisws

More?

[kaynezhang]

It seems it is a jar collision problem ,maybe there are more than one versions of xml parsing lib(for example xerces ) in your classpath ,and JDK is not choosing the right one.

[mikerawlins]

I had xml-apis.jar and xerces.jar in library path. Commenting out xml-apis.jar had no effect. Commenting out xerces.jar changed the exception to this:

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/xml/ws/developer/WSBindingProvider   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.SunRIPortProvider.createPortObject(SunRIPortProvider.java:84)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.getPortObject(AbstractPortProvider.java:458)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.AbstractPortProvider.getRepositoryServicePort(AbstractPortProvider.java:280)   at org.apache.chemistry.opencmis.client.bindings.spi.webservices.RepositoryServiceImpl.getRepositoryInfos(RepositoryServiceImpl.java:69)   at org.apache.chemistry.opencmis.client.bindings.impl.RepositoryServiceImpl.getRepositoryInfos(RepositoryServiceImpl.java:85)   at org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl.getRepositories(SessionFactoryImpl.java:109)   at org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl.getRepositories(SessionFactoryImpl.java:96)   at com.harbinger.mek.vm.repository.alfresco.AlfrescoRepositoryHelperImpl.repositoryLoginWS(AlfrescoRepositoryHelperImpl.java:226)   at com.harbinger.mek.vm.repository.alfresco.ECMRepositoryTestHarness.main(ECMRepositoryTestHarness.java:45)Caused by: java.lang.ClassNotFoundException: com.sun.xml.ws.developer.WSBindingProvider   at java.net.URLClassLoader$1.run(URLClassLoader.java:202)   at java.security.AccessController.doPrivileged(Native Method)   at java.net.URLClassLoader.findClass(URLClassLoader.java:190)   at java.lang.ClassLoader.loadClass(ClassLoader.java:306)   at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)   at java.lang.ClassLoader.loadClass(ClassLoader.java:247)   … 9 more‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Leaves me to wonder if I am missing some jar files for WSDL support. Any guesses or pointers? I looked around here but couldn't find what I was looking for:

Try to add “jaxws-rt.jar" into your classpath,you can download it here https://jax-ws.java.net/
