JspDynPage debugging

I am not able to debug JspDynPage components. Control never stops at a breakpoint. Debugging DynPage and AbstractPortalComponents was fine. But have problem with only JspDynPage components. Do I need to do any additional setting in the debug configuration??
I am working with Sneak Preview EP6.0 SP4 and Developer Studio 2.0.5
Thanks.

Hi!
If you creates a new Portal Application based on JSPDynPage with the wizard SAP Developer Studio, the wizard adds two properties (in portalapp.xml) to the component that should be deleted.
The properties are:
<property name="ComponentType" value="jspnative"/>
<property name="JSP" value="pagelet/hubba.jsp"/>
If you try to run the JSPDynPage with these properties, the JSPDynPage is <u>never</u> called and you will not be able to debug the component.
Cheers

JspDynpage debug

Hi,
I want to debug a portal application Iview.I have done the following and my application is not stopping in the breakpoints.
- using config tool i have set the debug mode on and the pot number is 50021.
- using sap management console ,i have restarted server process
- set the break point in doInitialization and doProcessBeforeOutput
- Configure the NWDS debug configuration for Remote java application.Set the host name to localhost and port as 50021.Selected debug mode as "Enterprise portal" from Common tabpage.
please help me if i missed something.

Not stopping in your breakpoints can have different reasons. Check the following list:
1. Does your IDE successfully connect to the engine?
2. If your source code is not in sync with the deployed one, you can set a "method breakpoint" rather than a "line breakpoint". In this case the engine will stop when this method gets invoked, independent of the concrete implementation line.
3. I can successfully debug my portal application from Eclipse (not NWDS), so I don't know if setting the debug mode to "Enterprise Portal" is needed at all.
4. Also a have debugged jspnative components, so I don't see why one should remove these properties in the portalapp.xml as stated in the previous post.

Dieter

JSPDynPage unable to debugging in NWDS?

Hi, I'm using EP 6 SP9 sneak preview edition to develop and test portal components. I'm running SAP J2EE engine in debug mode and I have successfully debugged AbstractPortalComponent.
I recently created a JSPDynPage component but unable to debug, I don't know why. When I copied the code from JSPDynPage and created a new AbstractPortalComponent, set some breakpoints debug seems to work but not working for JSPDynPage, any reason? Am I missing anything here?
Another question here is can we debug JSP as well?
FYI: I was able to debug JSPDynPage component when I exported EP5 JSPDynPage component into NWDS, it then created EP6 portal component structure and deployed into EP6.
Appreciate your help.
Thanks
Siva

Thanks Ganesh,
One of the link you provided had resolved my issue with debugging. All I did is remove the below two entries from portalapp.xml file
<property name="ComponentType" value="jspnative"/>
<property name="JSP" value="pagelet/InitialPage.jsp"/>
These 2 entries are created by default for JSPDynPage components by the wizard in NWDS SP9. I don't know if this is same in later releases.
I can debug now.

Debugging DynPage/JspDynPage application

Hi All,
I'm trying to debug DynPage/JspDynPage.
I followed this thread: Debuggin of Portal Components
and this weblog: NetWeaver Portal Debugging
When I try to debug I see that the application's threads are running but the the browser doesn't open and the application doesn't stop at the breakpoints.
No error messages are displayed.
What do I need to config in order to debug portal applications?
Thanks,
Omri

Hi Patrick,
I tried running the application from portalapp.xml and I got error (see attached pictures).
http://img69.imageshack.us/img69/9522/debugprespective7hq.jpg
http://img83.imageshack.us/img83/4231/remotedebug8zt.jpg
Do I need to add some entries in the portalapp.xml?
(The debug session is working because I can see the threads are running).

Hi Quatre ,
-Select the breakpoints in your Dynpages /beans in ur project
-To debug u have to change the prespective to debug which u can find in
window/open prespective /Debug in NWDS
-Select the Run/Debug or the Debug icon in the toolbar.
-Fill the project name ,application name in the in the wizard opnend .
- Follow the debugging using the next step over F6 ,step return F7 keys .
These link may be helpful:

MYSAPSSO2 - JSPDynPage - (Re)Authentication Issue

Good Afternoon,
I have created a JSPDynPage and deployed on an EP7.0 2004s SP14 server. You can access the JSPDynPage
by using http://host:port/irj/servlet/prt/portal/prtroot/<jsp_dyn_class>
When I browse to the location I am challenged for credentials. I enter a valid Portal user name and password and am granted access. However if I browse to the http://host:port/irj/portal I have to re-authenticate. It seems there is double authentication and my question is why? Usually you can enter the portal at irj/portal and then enter /useradmin etc in the address bar and gain access to the requested portal component. I have put debug listeners on the JSPDynPage showing a valid MYSAPSSO2 cookie exists and I can retrieve the username, (UMFactory, IAuthenticator) etc. Do I need to configure a SAP Login Ticket for the Portal to Access itself. Using the DiagTool I have traced both authentication methods (entering from /irj/portal and /irj/servlet/prt/portal/prtroot/<jsp_dyn_class>) and they appear identical.
The reason I am using this is the 'quick links' functionality is not working; I suppose a separate issue and we want to provide a users with a link that will insert them into the requested iView. Thanks!

Good Morning,
Thanks for your response. You may be right, as a user my domain name is <Associate#>@<DomainController>.<DOMAIN>.COM and the server resides at <portal_hostname>.<DOMAIN>.com. Could this be causing the issue? You would think not since in both cases the Portal Server is issuing the ticket - when accessing my JSPDynPage and at /irj/portal. I exchanged keys & followed 701205 to establish SSO between an SRM 5.0 system. When SSO'ing to the ITS - SRM Logon screen - if I first go to the portal's /irj/portal, logon and then go to the SRM Logon screen I am SSO'ed in. However, if I go to my JSPDynPage, authenticate and then enter the SRM's logon screen I must enter username and password (essentially the MYSAPSSO2 cookies is not passed?). I then created a 'system' connection in the Portal's System Administration area for the SRM system and under the Support area I can run SAP Transactions in the SRM (ABAP) system, such as sm21 etc. Curious.

JSPDynPage not working

Hello Friends,
   I am trying to create a portal applicaton. I have a JSPDynPage (which calls the initial JSP) and a bean to store the client data. I am facing a strange problem here. when the user hits a button in the Jsp page i am doing some process in the onClick event for the button in the JSPDynpage and setting a flag file so that the controller calls the next JSP. The problem is the same JSP is getting showed up even after hitting the button. Is there anyway to debug this? I even doubt if the JSPDynPage is really getting executed. Coz even if I comment out this.setJspName("initial.jsp") the jsp gets displayed.
I am just having a single component and my portalapp.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>
</application-config>
<components>
    <component name="FR100JSPDynPage">
      <component-config>
        <property name="ClassName" value="com.test.fr100.FR100JSPDynPage"/>
      </component-config>
      <component-profile>
            <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
</components>
<services/>
</application>
Can anyone explain this?
Regards,
Nathan.

Hello All,
Thanks for the reply. The problem got solved. There was a bug in the controller program. The JSP part is working fine now. Now I am facing another issue. The bean that i am having in the session is not available in the result jsp.
The following are the piece of codes that i use for session tracking..
JSPDynPage: doInitialization()
         IPortalComponentRequest request = (IPortalComponentRequest)this.getRequest();
          IPortalComponentSession session = request.getComponentSession();
         dataBean = new FR100Class();
        session.putValue("clientData",dataBean);
and I am setting few values for the Bean in the onClick event of JSPDynPage and few by calling an external java class say c1 by passing this bean instance to c1's void method(doesn't return any value).
Initial JSP:
<jsp:useBean id="FR100Bean" scope="session" class="com.test.fr100.FR100Class" />
Result JSP:
<jsp:useBean id="FR100Bean" scope="session" class="com.test.fr100.FR100Class" />
Here when i tried to read FR100Bean.getName() it returns null.
Where have i gone wrong?
Thanks in advance.
Nathan.

Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input

Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.
2.2] Host file updated in Windows-System 32.
3] In SICF following services are active,
3.1] default_host/sap/bc/webdynpro
3.2] default_host/sap/public/bc
3.3] default_host/sap/public/bc/webdynpro/viewdesigner
3.4] default_host/sap/bc/wdvd
3.5] default_host/sap/public/icman
3.6] default_host/sap/bc/gui/sap/its/webgui
3.7] default_host/sap/public/ping
3.8] default_host/sap/bc/error
3.9] default_host/sap/bc/echo
4] In SE80
4.1] Internet services-System-are published
4.2] Internet services-WEBGUI-are published
4.3] Utilities-Setting-ABAP Editor-Debugging-Username & New Debugger set.
4.4] Utilities-Setting-ABAP Editor-Editor-Front-End Editor(New) set.
5] In Su01 for user profiles sap_all & sap_new is assigned and role SAP_BC_WEBSERVICE_DEBUGGER is assigned.
6] The support packages are also updated to latest level.
7] Gone through following links but not getting any clues.

Hiding table columns in a table view in JspDynpage

hi,

Hi,
What senthil has given is for dynpage not for jspdynpage
If u r using jspdynpage
<hbj:tableView

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?

Firefox can't open normally without going through the "this is embarrassing" routine; nor does it close down properly; I get the "end program" message and have to say "end now"it also sticks frequently, i.e. screen freezes for a minute or more; should I uninstall and re-install to try and debug?
- I've used Firefox exclusively for around 2 years.
- My outlook express has no problems
- other programs seem unaffected; it seems peculiar to Firefox.
- my main use is surfing the net, primarily entering competitions on line via specialist competition sites.
- every day at some stage(s) I have to switch computer off as Firefox has got very slow/sticky/freezes.
I'm not techy by any means, but I can only thing of un- and re-installing to hopefully start with a clean slate.

Sounds like something is keeping Firefox from closing properly. See this: <br />

ERROR while debugging a SELECT..ENDSELECT

Hello All,
We get an error while we go into the select..endselect loop during debugging. Because of this if we try to do some research on existing program with Select-endselect..it fails in the second pass of this loop.
This problem was not there earlier, but after we upgraded from 4.6 to 4.7 this problem is bugging us..every day. Does any one have a clue why ?
Thanks!!

Hi,
debugging a SELECT...ENDSELECT statements brings to a LUW commit work if no other work processes are available for debug.
See OSS notes 675, 2104.
From OSS note 675 **********************************
Cause and prerequisites
Chain of causes:
      1. There is a statement in one of the Select loops, that leads to a database Commit (or Rollback).
      2. A database Commit causes the database to lose the cursor.
      3. The system cannot automatically continue within Select loop after loss of cursor.
Following statements lead to a database Commit:
    * All statements that cause a change of screen (CALL SCREEN, CALL DIALOG, CALL TRANSACTION, SUBMIT, I/W-Message)
    * BREAK-POINT/ Debugging
      . if no debug process free
      . always after regeneration (in order to release generation lock).
    * WAIT Here a work process is released and a Commit is executed.
    * COMMIT WORK/ROLLBACK WORK
From OSS note 2104 **********************************
Solution
The "COMMITWORK" message appears in the ABAP debugger when programs
orscreensrequireregeneration,or when not enough free capacity
is available inthesystem (or else the debugger blocks a system
process).
Normallyonly one work process is released for debugging. This
isgenerally insufficient ina developmentsystem, as processes
can be blocked for other reasonstoo(background processing,
CPI-C connections,andso on).
The number of work processes made available for debugging can
be configured using the profileparameter
                  rdisp/wpdbug_max_no
Forexample:
                rdisp/wpdbug_max_no = 10
setsthe maximum number of work processes made available for
debuggingto 10. It may be necessary to generally increase the
numberofwork processesatthis time (parameter rdisp/wp_no_dia).
In all other known cases, an error in the application program is
involved.
Regards, Manuel

DID YOU KNOW?: Debugging with BC4J Tester

Did you know that in JDeveloper 3.2, you can run the BC4J tester in debug mode to exercise your business components and hit breakpoints at the same time?
Just do the following:
[list]
[*]Expand the navigator node for your Application Module, revealing its XML and Java implementation files.
[*]Right-mouse on the YourAppModImpl.java file, and select Debug...
[list]
By default, it will debug using the "local mode" connection configuration. If you want it to debug using a difference configuration, just change the configuration name that appears as the 2nd argument in the launchTester call in the main() method of the application module implementation file.

grin Thanks, Steve.
Does this mean that in JDev 5.0 we're going to see an animated Steven Muench head in a tiny window in the lower corner, occassionally tapping on the glass to offer us hints?
