Enhancing The Application Flows

Hi every one.


I'm trying to change the flow of the example so I can land on the query.jsp page rather than going through the seltable.jsp.


As I understood from this http://www.chemaxon.com/forum/ftopic1098.html&highlight=jsp+forward+query+jsp post the seltable.jsp do more than table selection. I joined part of seltable.jsp code mainly the part that do the initialization and connection with query.jsp code and rename it to seltable.jsp so I can land on query.jsp directely.


Attached is the modified query.jsp and the here is the error I get.





Any help will be appreciated.





Thanks

The topic was moved to the "Structure search and chemical database" forum, my colleagues will answer you soon.

Problem solved.


If any one interested in my solution I'm willing to share it. There might be better ways of course.





Thank you.

Hi Saïf,





Actually I am trying to do the same thing as you! Since I am not a java expert, could you please try to give me the solution that you have found?





Thanks.

Hello





My solution was kind of a quick fix that kept me going.


I did some changes in seltable.jsp


Instead of selecting a table I hard coded my table name and get rid of part of codes that I don' need.


I made another copy of initsearch.jsp named it for example initsearch2.jsp


I believe this part could have been done in a better way by looking into the xml files of the software.


In this copy of initsearch2.jsp I add a line of code to forward the user query.jsp

Code:

<jsp:forward page="query.jsp" />

The pages I changed are attached.





As I said there should be a better solution that I will look into when I get time.


I'm involved in a lot other tasks now.


Hope this will help you and others.
