Not able to create the session in OSB console - Could not create directory <DOMAIN_HOME>/osb/config/sessions/weblogic

Sometimes we may receive the error "could not create directory <DOMAIN_HOME>/osb/config/sessions/weblogic" in the OSB console while trying to create the session.



There will be a multiple reason for this issue, in our case the root cause of the exception is the space is full for the mount  point

How to Fix

To resolve the issue add extra space to the mount point or clear some of the unwanted files and make the required space.

SCAC-50012 - Oracle SOA Suite 11g

This error will occur most of time compiling the Oracle BPEL component in Oracle SOA Suite with java embedded activity, If there is any issue with the java code this exception will be thrown.

We were facing the SCAC-50012 exception with the following code.

String orderID  =  ((oracle.xml.parser.v2.XMLElement) getVariableData("inputVariable","payload",'/client:process/client:input')).getFirstChild().getNodeValue();
String Title=("OrderID: " +orderID);                                        
setCompositeInstanceTitle(Title);

The actual  issue with the XPATH expression specified within the single quote(copy paste issue), the compilation became successful after converting the single quotes to double quotes.

String orderID  =  ((oracle.xml.parser.v2.XMLElement) getVariableData("inputVariable","payload","/client:process/client:input")).getFirstChild().getNodeValue();
String Title=("OrderID: " +orderID);                                        
setCompositeInstanceTitle(Title);

How to  create Repository Nodes thorough Java in Adobe Experience Manager(AEM)

We can create the repository nodes inAdobe Experience Manager(AEM) through Java API , the below code snippet will help us to create the nodes in Adobe Experience Manager(AEM).

private static final String BASE_PATH = "/etc/commerce/products"; // the folder under which the nodes should be created

//Get the Resource resolver from request - Creating the node through Servlet
ResourceResolver resolver = request.getResourceResolver();

//Get the Resource resolver through resolver factory - Creating the node through Service
@Reference
private ResourceResolverFactory resolverFactory;//Get the resolverFactory reference in the service

ResourceResolver resolver = resolverFactory.getAdministrativeResourceResolver(null);//Get the resolver

//Get the session
Session session = resolver.adaptTo(Session.class);

//Create the Node
Node node = JcrUtil.createPath(BASE_PATH+<<Node Name>>, JcrConstants.NT_UNSTRUCTURED, session);

//Set the required properties
node.setProperty("name", "sample");
node.setProperty("description", "sample");

//Save the session
session.save();

While creating the NT_UNSTRUCTURED node make sure the parent folder is sling:folder, the node will not be created if the parent node is of type nt::folder.
