Hi
I have a validation for email which should allow only , or ;

the validation works fine if I enter the following in the text field
mail1@email.com,,,,,,,mail2@email.com

but the validation does NOT work if I enter the following in the text fields
mail1@email.com;;;;;;;mail2@email.com

the following will work properly
mail1@email.com;mail2@email.com

this is the regular expression that I have written in my validator class



can anyone let me know what's going wrong here? any solution to this would be very much helpful.

Thanks in advance.

How can we prefix a string to EL expression for rich:modalpanel , something like this



wintype will be a parameterized value passed from another file and it could be "small" or "big" or "other", so for example if wintype is big then props.height_big value will be picked from props file.

props.height_ and props.width_ are the strings that should be appended.


Thanks in advance.

I have to pass value for id for a rich:modalPanel dynamically , as of now i am passing it as <ui:param.../> but that is not working.
My requirement is that I should have a overlay template with a specified dimensions and the body(content) of the overlay will change depending on different pages , I do not want to repeat the overlay code in all pages execpt the overlay content part. The code for template part of overlay and the implementation of template is here below. It would be great if you could suggest me a solution on this or any other alternative approach.

Thanks in advance


Template.jspx

Hi,
I am trying to read a flat file which has millions of records (more than 50 millions) and save the data read into database.
I am currently making use of collections framework but that is slowing down the processing (by fetching a few lines and parsing those lines and then again start from the point where last ended) so I would like to know if there is any best solution for this..
I am using JDBC for updating DB and a helper class that would read the flat file and update the collections and ultimate pass this collections object to DAO layer for further processing.

any help/suggestion in this regards would great,
Thanks in adv:

    The following is the error when I try to update the database.


    can any of you let me know if this is a licensing issue or any other issue, this application used to work fine when It was hosted on Tomcat, but when we deployed this application on BEA this error came up.
