Exceptions While Using RIDC API @ Webcenter

1) Unable to locate authentication handler for Content Server response: HTTP/1.1 502 Bad Gateway
Source breakpoint occurred at line 54 of MyManagedBean.java.
oracle.stellent.ridc.protocol.ProtocolException: java.io.IOException: Input terminated before being able to read line.
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:142)
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:107)
at MyManagedBean.RIDC_CreateFolder(MyManagedBean.java:54)

The code i was using to initialize the connection was:

IdcClientManager manager = new IdcClientManager();

IdcClient idcClient = manager.createClient("http://localhost:4444/idc/idcplg");

The problem resolved by changing the code to:

IdcClientManager manager = new IdcClientManager();

IdcClient idcClient = manager.createClient("idc://localhost:4444");

2) oracle.stellent.ridc.protocol.ServiceException: No service defined for null.
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:135)
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:107)
at MyManagedBean.RIDC_CreateFolder(MyManagedBean.java:54)

Reason: Ohhh....Very silly mistake. Following is the code with error:

dataBinder.putLocal("idcService", "COLLECTION_ADD");

Correct Code:

dataBinder.putLocal("IdcService", "COLLECTION_ADD");


3) oracle.stellent.ridc.protocol.ServiceException: Unable to display virtual folder information. Unable to open folder.
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:135)
at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:107)
at MyManagedBean.getFolderIDFromPath(MyManagedBean.java:165)

Reason: I was specifying only the folder name instead of complete path :)... Ex: RIDCFolder instead of /Contribution Folder/RIDCFolder.... in binder.putLocal ("dCollectionPath", path);


4) This time i was not getting any exception. But there was something wrong. I was trying to upload document, the code was working fine but the document was not uploading. The point to be noted is that there was error in code but i was not getting any exception. Actually, i was not using following code to get the document id of the document i was uploading:

DataBinder serverBinder = res.getResposeAsBinder();
S.O.P(serverBinder.getLocal("dDID"));

I re ran my code with above lines and i got my exception at res.getResposeAsBinder(); So it is important to use above line to ensure that the operation was successful and to save some time.

5) java.lang.RuntimeException: oracle.security.jps.service.idstore.IdentityStoreException: JPS-01520: Cannot initialize identity store.
This exception is is not related to RIDC but i got it suddenly while working. This cause my navigation model to stop working properly. In the logs of UCM managed server i found below exception:


javax.naming.CommunicationException [Root exception is java.net.ConnectException: t3://[2001:0:4137:9e76:2c71:1810:854e:e6a5]:9001: Destination unreachable; nested exception is: 
java.net.ConnectException: Connection refused: connect; No available router to destination]


Not sure, resolved it self in next run.

6) File size is to large and can't be uploaded: When using RIDC the default size of document that can be uploaded is 2 MB. In order to increase this limit, we need to make an entry in web.xml file. Under the Application option in Overview tab, expand Context Initialization Parameter and add following parameter:

Name : org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE
Value: The maximum file size in bytes

7) Invalid JCR Name or Path: I am still working on this exception.
