topic irregular error with RepositoryService in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/irregular-error-with-repositoryservice/m-p/164035#M117799 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I have Alfresco (2.9, but was the same with 2.1) instances running on tomcats on 4 machines as well as 1 virtual machine (xen). Operating systems are Windows XP and debian linux. My application is also running in the tomcats and connects to Alfresco. So I make connections from machine A to B, B to A, A to A, … a lot possibilities. Believe it or not: the following error depends on the connection.</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>java.lang.NullPointerException<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.AxisFault.makeFault(AxisFault.java:101)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.AxisClient.invoke(AxisClient.java:216)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.Call.invokeEngine(Call.java:2784)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.Call.invoke(Call.java:2767)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.Call.invoke(Call.java:2443)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.Call.invoke(Call.java:2366)<BR />&nbsp;&nbsp;&nbsp;org.apache.axis.client.Call.invoke(Call.java:1812)<BR />&nbsp;&nbsp;&nbsp;org.alfresco.webservice.repository.RepositoryServiceSoapBindingStub.get(RepositoryServiceSoapBindingStub.java:1078)<BR />&nbsp;&nbsp;&nbsp;de.mycompany.RepositoryBrowser.listDirectory(RepositoryBrowser.java:37)<BR />&nbsp;&nbsp;&nbsp;de.mycompany.webclient.List.doGet(List.java:50)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:690)<BR />&nbsp;&nbsp;&nbsp;javax.servlet.http.HttpServlet.service(HttpServlet.java:803)<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><SPAN>The last line within my application's realm is:</SPAN><BR /><PRE class="language-none line-numbers"><CODE>Node[] selfs = null;<BR />selfs = repositoryService.get(new Predicate(refs, Filesystem.STORE, null));<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><EM>refs</EM><SPAN> contains 1 valid (!) reference, </SPAN><EM>Filesystem.STORE</EM><SPAN> the standard store.

However, after the error occurred there may be a big time span until the next request which than works fine again without re-login or similar (until I wait 20 secs again…). For other connections no error occurs at all. For others every now and then. It seems it works better if the two applications don't reside on </SPAN><STRONG>one physical machine</STRONG><SPAN>.</SPAN><BR /><BR /><SPAN>Any hints on what I could have done wrong, how to search/get more precise information is much appreciated.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>Tim</SPAN><BR /><BR /><BR /><SPAN>—-</SPAN><BR /><BR /><SPAN>Another interesting scenario: Alfresco on machine X, my application on the virtual machine on X -&gt; every other request gives that error, 100% regular. Klick, error, refresh, works, refresh/klick, error, refresh, works…</SPAN></BODY></HTML> Mon, 21 Apr 2008 14:02:12 GMT tim-erwin 2008-04-21T14:02:12Z irregular error with RepositoryService https://connect.hyland.com/t5/alfresco-archive/irregular-error-with-repositoryservice/m-p/164035#M117799 Hi,I have Alfresco (2.9, but was the same with 2.1) instances running on tomcats on 4 machines as well as 1 virtual machine (xen).

After months…</SPAN><BR /><BR /><SPAN>As my setup is x users (with x sessions) connect to 1 application which connects (with 1 session) to alfresco, I couldn't use the standard way of session handling as in AuthenticationUtils. I really wonder how a ThreadLocal variable for authenticationDetails can help at all. Since it is stored "in a thread" of a pool of which the threads are assigned to users rather randomly it's not for sure the respective user is getting it back, is it?</SPAN><BR /><BR /><SPAN>Anyways, we don't have the authenticationDetails available which causes the </SPAN><STRONG>CookieHandler</STRONG><SPAN> to fail. Thus, I just removed it from the </SPAN><EM>WS_SECURITY_INFO</EM><SPAN>. Now, everything works fine. Is that an issue regarding session management? Or is it really just one session I have between my application an alfresco?</SPAN><BR /><BR /><SPAN>I thought such a setup (server talks to server) is a rather common setup. However, it seems the API is not really prepared for that.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>Tim</SPAN></BODY></HTML> Tue, 22 Apr 2008 08:43:38 GMT https://connect.hyland.com/t5/alfresco-archive/irregular-error-with-repositoryservice/m-p/164036#M117800 tim-erwin 2008-04-22T08:43:38Z
