Not able to create the session in OSB console - Could not create directory /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



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

XML-22036: (Error) Cannot convert result tree fragment to NodeSet - Oracle SOA Suite 11g

We are getting the below exception in runtime while passing the parameter and accessing the same from XSLT in Oracle SOA Suite.

</exception>

The actual issue is, the xsl:param name in the XSLT is different from the parameter name send from BPEL.




The issue got resolved after changing the xsl:param in XSLT as same as the parameter name in Oracle BPEL.

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);
