OSB – Publishing to Oracle WebLogic Server v10.3 at localhost…”. requested array is larger than heap


An internal error occurred during : “Publishing to Oracle WebLogic Server v10.3 at localhost…”. requested array is larger than heap

Solution: Goto C:\bea\user_projects\workspaces\default\.metadata\.plugins\org.eclipse.wst.server.core\publish  location
And delete the .bat files starting with publish*.bat e.g: publish0.bat, publish1.bat etc. After deleting try to publish application. This should solve ur problem. Even after doing this if the problem persists then delete the server domain and create new domain.

SOAP VS REST Web Service


SOAP – Simple Object Access Protocol
  1. Exposes Operations that implement/represent logic
  2. Provides loose coupling for integrating diverse systems
  3. Designed for distributed systems.
  4. Designed to be extensible – WS-*
  5. Standard error messaging – SOAP faults with standard code/ subcode for error types
  6. Aligns with enterprise application needs and goals.
  • Supports other transport protocols than HTTP – SMTP, JMS
  • Supports enterprise security with WS-Security.
  • Supports language neutrality
  • Supports ACID, Atomic transactions with WS-AT
  • Support Reliable Messaging with WS-RM
  • Easy governance with strong typing.
  • Broad development tool support

REST
- Good for Web service
- Exposes RESOURCES which represent data
- Uses HTTP verbs (GET / POST / PUT / DELETE)
- Emphasis on simple point – to – point communication over HTTP
- Supports multiple data formats
- Emphasizes stateless communication
SOAP
- Good for Enterprise services
- Exposes OPERATIONS which represent LOGIC
- Uses HTTP POST
- Emphasis on loosely coupled distributed messaging.
- Supports only XML and attachments
- Supports stateless and stateful / conversational  operations
- Supports asynchronous messaging
- String Typing
Why Rest is better than SOAP:
- REST can be consumed by any client, even a web browser with Ajax and javascript
- REST is light weight. 1 - Rest doesn’t require XML parsing.   2 - Rest consumes less bandwidth – doesn’t require a SOAP header for every message
- Can learn to use REST very easily.It’s just nouns and verbs
Why SOAP is better than REST:
- Building a client for REST can be challenging and difficult and building client for SOAP will be easy
- I can easily generate client-side artifacts from a WSDL
- I don’t want to write raw http calls
- I don’t want to look at the http response code for success/failure
- REST only supports HTTP/HTTPS
- HTTP is synchronous and in order to scale I need to be able to have asynchronous messaging.
- REST is not secure
- Parameters are part of URL
- No support for acquiring token
- RESTful services have no contract
- Have a WADL that specifies URL’s but not schema for object definition
