Abstract

A system and method for performing a lookup in a second namespace, the lookup being performed from a first namespace, whereby a component performing the lookup is not required to be configured for performing a lookup in the second namespace, the system and method further comprising: parsing a first lookup request for a URL tag, the first lookup request for an object located in the second namespace, the lookup request including a symbolic name corresponding to a target location in the second namespace, the URL tag corresponding to a URL context; searching the URL context for a provider URL corresponding to the symbolic name; and creating a second lookup request, the second lookup comprising the provider URL and the object'"'"'s name.

Claims

1. A computer implemented method for performing lookup across namespace domains, comprising:

parsing a first lookup request for a URL tag, said first lookup request being performed from a first namespace, said first lookup request targeting an object located in a second namespace, said first lookup request including a symbolic name corresponding to a target location in said second namespace, said URL tag corresponding to a URL context;

searching said URL context for a provider URL corresponding to said symbolic name; and

creating a second lookup request, said second lookup comprising said provider URL and said object name.

2. A method as in claim 1 wherein said first namespace and said second namespace are enabled for communication with each other.

3. A method as in claim 2 wherein said first namespace and said second namespace are disparate namespaces.

4. A method as in claim 2 wherein said first namespace and said second namespace are not configured as a federated domain.

5. A method as in claim 2 wherein said first namespace and said second namespace are enabled with JNDI for communication with each other.

6. A method as in claim 5 wherein said first namespace and said second namespace are disparate namespaces.

7. A method as in claim 5 wherein said first namespace and said second namespace are not configured as a federated domain.

8. A computer system for federating at least two namespaces, comprising:

at least two namespaces, said two namespaces being configured for communication with each other;

a regular naming context, said regular naming context being created by a regular naming context factory in response to said regular naming context factory receiving a lookup request from a component in a first of said two namespaces for an object in a second of said two namespaces, said regular naming context parsing said lookup request for a first URL tag, said first URL tag being indicative of said second namespace; and

a URL naming context, said URL naming context being created by a URL naming context factory in response to said regular naming said lookup request and in response to a second URL tag being included in said lookup request, said URL naming context parsing said lookup request for a symbolic name indicative of a provider URL, said provider URL being indicative of a target location in said second namespace.

9. An article of manufacture for lookups across namespace domains, comprising:

a computer useable medium having computer readable program code embodied therein for performing a lookup in a second namespace, said lookup being performed from a first namespace, wherein said first and second namespaces are disparate namespaces, comprising;

computer readable program code for parsing a first lookup request for a URL tag, said lookup request for an object located in said second namespace, said lookup request including a symbolic name corresponding to a target location in said second namespace, said URL tag corresponding to a URL context;

computer readable program code for searching said URL context for a provider URL corresponding to said symbolic name; and

computer readable program code for creating a second lookup request, said second lookup comprising said provider URL and said object name.
