How to avoid ognl exception.

Hi I have few form fields defined in my html but there is no corresponding
property in action. I am purposefully not defining them. Why i am doing
this is the same form can be submitted to two different actions based on
the requirement. so one action needs few and the other action needs few
form fields. In this case i always get the following exception. After this
exception the server response time is getting very low so how can i avoid
getting this exception. If there are corresponding properties in action the
struts have to set the values and if not it has to be silent. It should not
display the following exception. Kindly help me.

Re: How to avoid ognl exception.

Posted by Yaragalla Muralidhar <ya...@gmail.com>.

too much re factoring also confuses and makes it a great burden for
maintainers. If it is a simple 2-3 form fields that i am not using then let
them be there. It is because the 2-3 fields that are not used in one action
will be used in another action for the same form. we have different modes.
in "xx" mode it could be the same jsp but we dont use all the form fields
of it but if it is "aa" mode  then we use all the form fields of the same
jsp.

*Thanks and Regards,*
Muralidhar Yaragalla.

Re: How to avoid ognl exception.

Posted by Antonios Gkogkakis <gk...@tcd.ie>.

why don't you refactor your form and extract common functionality, so you
don't have unused fields being submitted. You or whoever maintains your
code will thank you some day.

Re: How to avoid ognl exception.

Posted by Yaragalla Muralidhar <ya...@gmail.com>.

Ya but if i don't do anything why should i have unnecessary setters in my
action. I am not arguing but it does not make sense to have just setters
which does nothing.

*Thanks and Regards,*
Muralidhar Yaragalla.

Subject: How to avoid ognl exception.

Hi I have few form fields defined in my html but there is no corresponding
property in action. I am purposefully not defining them. Why i am doing
this is the same form can be submitted to two different actions based on
the requirement. so one action needs few and the other action needs few
form fields. In this case i always get the following exception. After this
exception the server response time is getting very low so how can i avoid
getting this exception. If there are corresponding properties in action the
struts have to set the values and if not it has to be silent. It should not
display the following exception. Kindly help me.
