Abstract

A portlet state maintenance system can include a portal page setup component configured to generate a logical form in a single portal page from a multiplicity of forms defined within portlet markup aggregated into the single portal page. A portal state save component further can be configured to save state values for selected portlets defined within the logical form. Finally, a portal state restore component can be configured to restore the saved state values in refreshed portlet markup for the selected portlets. Notably, a refresh timing component further can be configured to embed submit auto-initiation logic in the single portal page responsive to identifying a dynamic refresh requirement associated with the portlet markup in the single portal page. Finally, a portlet markup cache can be coupled to the portal state restore component.

Claims

1. A portlet state maintenance system comprising:

a processor;

a portal page setup component connected to the processor and configured to generate a logical form in a single portal page from a plurality of forms defined within portlet markup aggregated into said single portal page;

a portal state save component connected to the processor and configured to save state values for selected portlets defined within said logical form; and

,

a portal state restore component connected to the processor and configured to restore said saved state values in refreshed portlet markup for said selected portlets.

2. The system of claim 1, further comprising a refresh timing component configured to embed submit auto-initiation logic in said single portal page responsive to identifying a dynamic refresh requirement associated with said portlet markup in said single portal page.

3. The system of claim 1, further comprising a portlet markup cache coupled to said portal state restore component.

4. A portlet state maintenance method comprising the steps of:

receiving a submit request specifying a set of form field data in a portal page comprising a plurality of portlets aggregated within said portal page;

identifying a specific portlet in said portal page as a source of said submit request and forwarding a submit request and portions of said form field data associated with said specific portlet to a portlet application corresponding to said specific portlet;

associating others of said form field data with respective ones of said portlets, storing said others of said form field data, refreshing each portlet application corresponding to said respective ones of said portlets to produce refreshed portal markup, and populating form fields in said refreshed portal markup with said stored form field data; and

,

aggregating said refreshed portal markup and portal markup produced by said forwarded submit request in a new portal page; and

,

forwarding said portal page in response to said received submit request.

5. The method of claim 4, wherein said aggregating step comprises the steps of:

stripping tags from said refreshed and produced portal markup which denote individual forms in each of said portlets; and

,

adding a single set of form tags to said new portal page to denote a single, logical form.

6. The method of claim 5, wherein said stripping step comprises the step of converting each <

FORM>

tag in said refreshed and produced portal markup to a comment tag.

7. The method of claim 4, further comprising the step of caching said refreshed and produced portal markup.

8. The method of claim 7, wherein said refreshing step comprises the step retrieving cached ones of refreshed portal markup in lieu of refreshing each portlet application corresponding to said respective ones of said portlets to produce refreshed portal markup.
