How to Generate a Java file for a JSP Page

Hi ,
I am using weblogic11 .
I am working on a JSP page which nearly consists of 4000 lines of code.
I need to debug the file , but weblogic server is not generating the java file for the JSP pages .
Please let me know how can i genertae Java file for the jsp pages ??

JSPs are compiled into servlets automatically and those classes are stored in WEB-INF/classes folder. Servlet engine handles servlets.

How to generate an XML file for an animation of IK armature

Can someone please tell me how to generate an XML file for an animation of IK armature.
I have a 5 keyframe/16 frame animation of a human character made up of a series of moveiclip symbols that is animated with an IK armature. I need the XML information from the animation.
When I go to Commands > Export Motion XML I get the error message "There is more than one object on frame 1" and then nothing happens.
Thank you,
c

I hope that's not the case. I want to write to adobe about it. I think it's a great feature and it functions really well even though it is not a very developed IK tool. My biggest issue with it is ouput options and integration with motion tweens.
I have seen a lot of examples of animators using it online, just no one talked about output. I just feel it hasn't been developed. It can generate a sprite sheet but only for a single pose frame of the animation, and not all the key frames or pose tweens. I find that functionality quite odd, as if adobe just forgot about IK when added in sprite sheets, etc. and the reason it half works is just an accident.

How to generate the ATR files for reports with out manually?

Hi all,
how to create the ATR files for reports in OBIEE 11g with out manually?
is there any other method to create the ATR files by using the OBIEE Server?
please provide me the solution for this?
we are creating manually for each and every report, it is time taken process how can we generate ATR files automatically
by using the OBIEE Server?
Thanks,

Hi,
I am afraid not.ATR are attributes files contains the object's full name, access controllist (ACL), description, and so on.Each catalog object has a corresponding attributes file, I am not sure why do you have to generate the atr files.In case you need info about atr files: http://businessdecisionsystems.com/blog/?p=7
If you have huge number of similar reports(with filter variations and same kind of layout), try to play around with the xml to minimize the development effort.
Rgds,

How to include a .class file in a jsp page

hi everyone,
i know the syntax as:
<%@ include file = "filename.class" %>
then at run time the server could not find the class file
if i use,
<%@ page import = "FileName.class" %>
then also the same problem persists
& if i use
<jsp:include page = "Relative address"/>
the problem still remains as it is...
please help me out...i am working on developing an EJB application in which client interacts with server's Stateful session bean through a jsp page...it is necessary for me to include the home interface class file in my jsp page.
P.S. do not suggest me to include the class file in a package & then use

"package University does not exist".How can i overcome this problem. The package University, which you are trying to import, must be in the classpath. If you removed it then you will have to add it back.
i have tried my best..but tell me if there's any possible way of including a class file in the jsp page without involving a package.No, there isn't.
If not,then pls help me to generate the class file of my home interface within a package called test.Read the New To Java Tutorial and understand how packages work.

How to generate the trace files for remote db link session's?

User are complaining, the db link queries are performing slowness..
how to enable the sql trace session for db link's in remote database...
Is there any way to enable sqltrace for the dblink session ?
if not how to enable the sql trace for entire database level, rather than session based...

An explain plan of the SQL being ran on the local database will review the SQL being passed to the remote db. You can then explain that SQL on the remote db.
I have had to tune a few distribued queries so more than likely the explain plan alone will be enough to allow you to tune the query to improve performance. If not then you can go to the trouble of trying to set up dual traces.

How can I use java swing class in JSP page design

I am a new developer in Java server pages. I want to use layout managers available in java swing classes to design the page. Can any body suggest me a way to do this.Is it possible if I do it with servelets.

So, you want to use layout managers within your JSPs?
The immediate answer is that "it isn't a good idea". The more considered answer is "tell us what you're up to".
Are you coding all presentation within a traditional JSP? That is, HTML, customer or library tags and/java scriptlets?
Or are you building your HTML within your servlets and sending that back to the browser?
If the first, then you are probably better off either using explicit HTML tables (or the equivalent custom tags) or finding a library that you can use.
If the second, you can write classes similar to the Swing layout managers that end up being a fancy way of putting elements into an HTML table. We have exactly that in my current environment. I wouldn't recommend rolling your own and I'd tend to leave all that presentation stuff to the JSP.
In any case, you can't really use the Swing layout managers as they are for an entirely different pradigm.

How to keep the generated java classes for compiled jsp in WL9.2 Workshop

Hi all,
 
 It should be a very simple question for most of you, however, it seems a bit tricky to me: how to configure the Weblogic 9.2 workshop so that we could keep the generated java files for the compiled jsp when we ran the application within WL 9.2 workshop?
 
 I try some configurations, but not working. Also, where are the generated java files stored?
 
 Thanks for the help!

 Edited by wingagnes at 03/21/2008 7:51 AM

Hi yzeng,
 
 Thanks for the reply. If I change the jsp-descriptor into the following:
 
 <jsp-descriptor>
 
 <keepgenerated>true</keepgenerated>
 
 <working-dir>D:\temp\golGenerated</working-dir>
 
 <debug>true</debug>
 
 </jsp-descriptor>
 
 I will get the following error message:
 
 cvs-complex-type.2.3.d:Invalid content was found starting with element 'precompile'. No child element is expected at this point.
 
 Thanks,
