J2EE Filter for /irj application

Hi,
i developed a J2EE Filter for irj application but i am getting some problem:
1) The irj application cannot load the J2EE Filter; it throws a ClassNotFoundException. I think that the problem is linked with a
    ClassPath/ClassLoader issue.
2) I don't know the session attribute name that stores the URL alias used by a user during logon step. I have to set up to null
     this attribute in order to obtain a recomputation of the portal desktop to show when a user change application using
     different alias.
These are the steps:
1) I made a jar file for the filter linked to a .sda file through NWDS.
2) I deployed this sda file throug NWDS
3) I changed the web.xml to configure the new filter component
4) restart the server but not worked.
Can anyone help me please?
Carlo Paglia

Hi,
the file is correctly located in the dir that you suggested. Opening Visual Administration tool i can see the entry "EnteprisePortalFilterLibrary" in the Libraries section linked with the jar name.
Restarting the server i obtain again ClassNotFoundException. I think that the problem is correlated to the server ClassPath but i don't know how to configure it.
Have you got other suggestions?
Kind regards,
Carlo Paglia

11.1.1.4 - MDS-00068 Error for the Application using user customization

Hi All,
I would like to check on this forum before I submit a SR. We have upgraded our ADF APP from 11.1.1.3 to 11.1.1.4. Many bugs are fixed, however while deploying the application we get following warning on integrated WLS Logs and application deployed successfully. The same app is working ok in 11.1.1.3. Also, if I deploy this application on Standalone WLS server and try to go to Enterprise Manager MDS configuration page for this Application it gives me a message - "MDS configuration information is not found. This application does not use MDS repository or MDS repository may not have been configured properly".
Any help would be appreciable.

Hi Frank,
I was able to solve the issue after isolating it to ADF faces caching filter. We are using ADF faces caching filter for our application and we have defined <caching-rules> tag in adf-config.xml file. I found that <caching-rules> was part of the schema definition of namespace "http://xmlns.oracle.com/adf/config" till 11.1.1.3 and now in 11.1.1.4 it is not anymore and that's why just specifying <caching-rules> tag was working in 11.1.1.3.
To solve the error I changed caching-rules to read from http://xmlns.oracle.com/adf/faces/rich/acf namespace. Now my caching rule tag in adf-config.xml looks like given below.
<caching-rules xmlns="http://xmlns.oracle.com/adf/faces/rich/acf">
<caching-rule id="cache-js">
<cache>true</cache>
<compress>true</compress>

Reports 9i/10g J2EE Thin Client for Websphere Application Server 5.x /6.x

We are having Reports developed in 6i which needs to be migrated to Reports 9i/10G and we want to deploy these reports in web using Websphere Application Server 5.x /6.x without Oracle iAS.
Do we have Reports 9i/10g J2EE Thin Client for Websphere Application Server 5.x /6.x and if so please let me know.
Also if anybody has the configuration details please let me know?
Thanks in Advance.

No there is not. I don't think you can use reports services with Websphere - besides as far as I know it is not supported by Oracle (not anywhere in their support matrix).

J2EE server stops while stopping irj application

Hi
We are getting Problem while trying to stop irj application before applying Patch 2 SP2 in EP 6.0. The server stops and displays message connection Lost in admin tool.
Pl help me to solve the Problem.
Regards
Atul

it stops every time if i make some changes. it is eclipse or bea-plugin which thinks the server has to be restarted/redeployed and so the server will be stopped (that's what i think)
i could now "resolve" the problem with deactivating the builders on the utility-project where my beans are located.
Properties/project/builders:
[X] Java Builder
[ ] Faceted Project Validation Builder
[ ] Validation
[ ] Web Logic J2EE Library Framework Validator
this is a quite adventurous solution! if i restart the workbench with the configuration above, eclipse will migrate the project and "Web Logic J2EE ... Validator" is active again and doubled. This looks like so and it is still working:
[X] Java Builder
[ ] Faceted Project Validation Builder
[ ] Validation
[ ] Web Logic J2EE Library Framework Validator
[X] Web Logic J2EE Library Framework Validator

How to deploy one common filter for all web applications

I want to deploy a filter for all the web applications i have running on weblogic server. I don't want to deploy the filter just within a specific web
context, was able to achieve this on tomcat as it provides a common web.xml
which will apply to all web apps. But i don't know how to achieve this on Weblogic. Your help would so much appreciated.

Thanks Vidyut! You've answered my question.
I placed the jar file in the $CATALINA_HOME/shared/lib directory. But where should I place the taglib TLD file? And how should I reference it in web.xml?
Currently, my web.xml is as follows and it doesn't work.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<taglib-uri>http://abc.com</taglib-uri>
<taglib-location>c:\Tomcat\shared\lib\mytags-taglib.tld</taglib-location>

Thanks again!

Hey Seshu
1>By default it'll be in
C:Documents and Settings<user>.dtc
2>FYI we dont deploy applications in EP, we deploy in the J2ee engine and portal just a component on top of the java engine.
An Administrator can deploy the applications developed.
or anyone can deploy applications knowing the SDM password

I want to create home page for my application with short URL

I want to create home page for my application with short URL
as when I want user to use my application user must go to URL like this
http://127.0.0.1:7101/My-Project/faces/app/empModule/allEmployees/viewMyEmployees.jspxI want the user to use short URL , How can I use shorter URL not all this one.
I want shorter URL for my application not to write full path .
thanks in advance.
Edited by: user611775 on Oct 31, 2010 10:21 PM

Well,
it's up to you. The first part (Mcit-Project-ViewController-context-root) is the context root which you define in the view controller project. 'faces' is the name the servlet filter reacts on. You can't omit it but shorten it in web.xml. The rest is your directory structure. I'm not sure how to shorten this other as to move the jspx files back into the web root folder.
By the way an ADF faces app never uses the .jspx at the end of the url. If you specify '.jspx', you only render the page but don't start the work flow.

How to set filter for few Setup Objects on Geneneral Foundation?

Controlling the download of sub-entities:
By default all sub-entities are downloaded. Pass a non-existing value
for the parameter (primary key) of the sub-entity if you don't want to
download a specific sub-entity.
For example, if you don't want to download the values of a value set,
then use following input to FLEX_VALUE attribute while setting filter;
FLEX_VALUE='THIS_IS_A_NON_EXISTING_VALUE_I_DONT_WANT_TO_DOWNLOAD_VALUES'
VALUE_SET
Notes:
- To download '$FLEX$.%' value sets pass '$FLEX$.%' argument.
- Upload API automatically submits the hierarchy compiler request
- FLEX_VALUE_SET_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Value Set Values.
VALUE_SET has subenities such as VSET_SECURITY_RULE, VSET_ROLLUP_GROUP and VSET_VALUE.
Setting value for attribute FLEX_VALUE_SET_NAME downloads all the subentities. If you want
to restrict the subentities, set appropriate filter at VSET_SECURITY_RULE, VSET_ROLLUP_GROUP
and VSET_VALUE.
Parameters:
VALUE_SET
| FLEX_VALUE_SET_NAME : Value set name.
|
+-VSET_SECURITY_RULE
| FLEX_VALUE_RULE_NAME : Value set security rule name.
| PARENT_FLEX_VALUE_LOW : Independent value for the dependent value sets.
|
+-VSET_ROLLUP_GROUP
| HIERARCHY_CODE : Hierarchy (rollup group) code.
|
+-VSET_VALUE
PARENT_FLEX_VALUE_LOW : Independent value for the dependent value sets.
FLEX_VALUE : Flexfield segment value.
DESC_FLEX
Notes:
- Upload API automatically submits the flexfield compiler request
- Upload API automatically submits the DFV view generator request
- APPLICATION_SHORT_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Descriptive Flexfields.
DESC_FLEX has subenities such as DFF_REF_FIELD, DFF_CONTEXT and DFF_SEGMENT.
Setting value for attributes DESC_FLEX and DESCRIPTIVE_FLEXFIELD_NAME downloads all the subentities.
If you want to restrict the subentities, set appropriate filter at DFF_REF_FIELD, DFF_CONTEXT
and DFF_SEGMENT.
Parameters:
DESC_FLEX
| APPLICATION_SHORT_NAME : Application Short Name.
| DESCRIPTIVE_FLEXFIELD_NAME : Descriptive Flexfield Name.
|

+-DFF_CONTEXT
| DESCRIPTIVE_FLEX_CONTEXT_CODE : Context Code
|
+-DFF_SEGMENT
END_USER_COLUMN_NAME : Segment Name
APPLICATION_COLUMN_NAME : Column Name
KEY_FLEX
Notes:
- Upload API automatically submits the flexfield compiler request
- Upload API automatically submits the KFV view generator request
- Upload API automatically submits the structure view generator request
- APPLICATION_SHORT_NAME is a required argument for download.
You can find the following parameters in Set Filter screen of Key Flexfields.
KEY_FLEX has subenities such as DFF_REF_FIELD, DFF_CONTEXT and DFF_SEGMENT.
Setting value for attributes APPLICATION_SHORT_NAME and ID_FLEX_CODE downloads all the subentities.
If you want to restrict the subentities, set appropriate filter at KFF_FLEX_QUAL, KFF_SEGMENT_QUAL,
,KFF_STRUCTURE,KFF_WF_PROCESS,KFF_SH_ALIAS,KFF_CVR_RULE and KFF_SEGMENT.
Parameters:
KEY_FLEX

PARENT_MENU_NAME Name of the menu to start downloading at. If this
parameter is specified on its own, that menu and
all its children will be downloaded. If specified
with FUNCTION_NAME and/or SUB_MENU_NAME, then only
the menu entry with that function and/or submenu name
immediately under the PARENT_MENU_NAME will be
downloaded.
FUNCTION_NAME Function name to limit download to. If this parameter
is specified then PARENT_MENU_NAME must also be
specified in order to download menus. Specifies

Set filter for only one column in tableview

Hi
i am using in MVC a htmlb:tableview with filter in only one column of 8.
This is all working fine, except that the user can enter a searchsting in the filterfield for all columns, but in handle_event (of the controller) ; i only react to a text in the filterfield of column 4 and ignore all other filtertext , which were maybe entered in the other columns.
My question:
how can i enter the filter only for one column, in a way that the user cannot enter any text in the filterfield of the other columns, only in column 4 ?
my view:
<htmlb:tableView id = "requirements"
 table = "//model/pdst_reqs"
 filter = "APPLICATION"
 keyColumn = "EXTID"
 iterator = "<%=model%>"
 footerVisible = "FALSE"
 encode = "TRUE"
 visibleRowCount = "<%=model->rowcount%>"
 width = "100%"/>
Best Regards
Britta

You can disbale the Filter for the particular column by setting the DISABLE_FILTER in the Iterator method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS. Here is the sample code
method IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS .
CLEAR p_column_definitions.
CLEAR p_overwrites.
data tv_column TYPE TABLEVIEWCONTROL.
tv_column-COLUMNNAME = 'FLDATE'.
tv_column-SORT = 'X'.
tv_column-EDIT = 'X'.
tv_column-ONCELLCLICK = 'MyCellClick1'.
tv_column-title = 'Date '.
APPEND tv_column TO p_column_definitions.
CLEAR tv_column.
tv_column-COLUMNNAME = 'PRICE'.
tv_column-horizontalAlignment = 'right'.
tv_column-verticalAlignment = 'middle'.
tv_column-ONCELLCLICK = 'MyCellClick2'.
tv_column-title = 'Currency'.
tv_column-EDIT = 'X'.
tv_column-DISABLE_FILTER = 'X'. " <-------Like this
APPEND tv_column TO p_column_definitions.
endmethod.
Hope this will solve your problem.

Portal requests don't hit the deployed J2EE filter

Hi,
What I am tring to obtain is that all requests are filtered via a J2EE filter. I've deployed the filter and tested it successfully. The filter mapping was set to "/*" so that it catches all requests. It works fine when tested at the J2EE level.
The problem comes when I tested it within the portal. The filter doesn't seem to be hit (because upon hitting some values are stored in the HttpSession. A session dump shows interesting results; the test at the J2EE level (via a servlet) shows the values set correctly in the session, as below:

The test at the portal level (via a portal application PAR deployment, jsp) shows different results, even if the session ID stays the same. Both tests were made in the same browser window.

Now the question: why the filter is not being invoked? Also, where is the object named TEMP_LANG from the first test? What am I missing here?
Thank you,
Adrian

What I noticed when I had a similar problem was that it matters which order the definition of the filter is declared in the web.xml file. Try playing around with these settings and see whether this sorts it out.
Perhaps even post the web.xml file so that we can check it is configured correctly

Including External JARs for Java Application in OC4J

Hi Experts,
Here is my requirement.
I have developed my Java application using Tomcat Server & Eclipse. In my application I have used some External JARs & imported the classes in my JSP.
Now that I'm using OC4J Server instead of Tomcat I'v no clue as to where I have copy these External JARs for my application to work.
I have installed OBIEE-Client which includes OC4J server. The path where I have placed my application is as below
*"C:\OracleBI\oc4j_bi\j2ee\home\default-web-app"*
If I run my application the server does not import the classes in the JSP which we include using Import statement using JSP tags (*ex* - <%@ page import = "org.apache.commons.fileupload.*"%>).
This is the location which I found, where I need to put my Java-J2EE application. This OC4J_BI comes with OBIEE.
Kindly help me out on where to place these External JARs exact location in OC4J.
Also let me know if I have to alter any configuration/xml file (if so pls specify the file name & its location).
Thanks in advance,
Venky

You can either include the external libraries in the application, by placing them into WEB-INF/lib, or you can import them into the server as "shared libraries", normally you'd use the "enterprise manager" application to do this. Having loaded a shared library you then add it to the classpath when you're deploying the application.

F4 for employee select options in WD for abap application

Hi,
I have defined a select option for employee selection in my WD for abap application. The only problem is that I cannot get a f4 help button to be displayed. I have defined the select option using the following code :
wd_this->m_wd_select_options = wd_this->wd_cpifc_select_options( ).
init the select screen
wd_this->m_handler = wd_this->m_wd_select_options->init_selection_screen( ).
create a range table that consists of this new data element
lt_range_table = wd_this->m_handler->create_range_table(
i_typename = 'PERNR_D' ).
add a new field to the selection
wd_this->m_handler->add_selection_field(
i_id = 'PERNR_D'
it_result = lt_range_table
i_read_only = read_only ).
I have tried adding entries for the parameter help_id but still cannot get a f4 button.
Thank you in advance for any assistance provided.

Hi,
Try this.
DATA lo_interfacecontroller TYPE REF TO iwci_wdr_select_options .
lo_interfacecontroller = wd_this->wd_cpifc_select_options( ).
DATA lo_r_helper_class TYPE REF TO if_wd_select_options.
lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).
Creating range table
DATA lt_range TYPE REF TO data.
CALL METHOD lo_r_helper_class->create_range_table
EXPORTING
i_typename = ''PERNR_D'
RECEIVING
rt_range_table = lt_range.
Disabling the global options
CALL METHOD lo_r_helper_class->set_global_options
EXPORTING
i_display_btn_cancel = abap_false
i_display_btn_check = abap_false
i_display_btn_reset = abap_false
i_display_btn_execute = abap_false.
Adding the selection field
CALL METHOD lo_r_helper_class->add_selection_field
EXPORTING
i_id = 'PERNR_D'
I_OBLIGATORY = ABAP_TRUE
i_value_help_type = if_wd_value_help_handler=>CO_PREFIX_SEARCHHELP
I_VALUE_HELP_ID = 'PREM'
it_result = lt_range.
Check this artcle for more details which uses VBELN as select option with search help.
