How to display oracle BOLB column data forms
Hello Francois ,
I also want to display a BLOB column value on Oracle front-end (but this is oracle form 6i version)
I tried your below method but i was not able to make it work....
it displays the other details wen quired but not the blob data column
please help --- urget solution required
<<<<<<<
Create a block based on the table you have the BLOB image, then use an Image Item based on that BLOB column. All you have to do, then is an execute_query() instruction to populate the Image Item.
Francois
I'm not convince that the null pointer exception is coming from the database. Rather, whatever you wrote to package the result might be at fault. Regardless, typically, to avoid the web container swallowing an exception is to catch it yourself. Your database call will need to catch the exception and repackage it for the JSP. A bad style would be to use scriptlet and catch the exception, but it could be useful for debugging.

How to Display an Image on my FORM
Good Day!
I would like to ask some help from you guys with my problem on how to display an image on my form. I would like to display my uploaded image on my form but instead of an image, the get_blob_file is showing. By the way, I'm using Apex 4.1
I downloaded the Order Entry Sample Application and followed the Page 6, the Product Details. I even made snapshots of each details from Page Rendering to Page Processing in order not to miss a thing.
At the moment, I was able to upload or store the image on my created Oracle table and also able to retrieve it on the Download Link Text with Content Disposition value of Inline, provided by APEX Settings. If I invoke the Download link beside the file browser, a page with the image will be shown, below is the address:
http://127.0.0.1:8080/apex/apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6&p_content_disposition=inline
However, instead of showing the image on a region, below is the one showing on my Form:
<img src="apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6" />
As you can see the parameter values are the same but I know I missed something that's why I'm here :)
I would highly appreciate all the help you can provide and many thanks in advance.

How to Hide/show the columns data while doing Drill down or drill up
Hi ,
How to Hide/show the columns data while doing Drill down or drill up in webi report .
Does it possible BO 3.1 version ?
Please suggest me on this.
Thanks & Regards
VenkatWhile that is not there yet, you can make use of the show when empty yes/no in combination with alerters.
So I have an alerter applied to every cell of the table.
When a condition is true (say I drilled down) I just put = "" in every cell, emptying the table,
because its now empty and doesn't need to show, it wont.
For the detail table I use the opposite, so when you drilled down it becomes visible...
Hope this helps all that do not have 40 yet
Good luck,

How to handle the BOLB column Using JDBC adapter
Hi,
I want to sending of a BOLB column from a DB2 database table to another DB2 database, and the sender and receiver both by using JDBC adapter. The two tables in each other database have the same columns.
Here is the table's structure:
<ID>string type</ID>
<PDF>blob type</PDF>
Also, i haved create two DataTypes in PI system.
Sender DataType:
ns:DT_PDF_Req xmlns:ns="http://XXXXX.com/sap/xi">
<row>
<ID>1</ID>
<PDF></PDF>
</row>
</ns:DT_PDF_Req>
Receiver DataType:
<ns0:DT_PDF_Res xmlns:ns0="http://XXXX.com/sap/xi">
<STMT>
<dbtable action="INSERT">
<table>tablename</table>
<access>
<ID></ID>
<PDF></PDF>
</access>
</dbtable>
</STMT>
</ns0:DT_PDF_Res>
When test this interface, i found the that we can get the data, but when execute the insert stms the follow errors occured in RWB :
<ERROR>
Could not execute statement for table/stored proc. "DBDPUSER.pdf" (structure "STMT") due to com.ibm.db2.jcc.b.nm: DB2 SQL Error: SQLCODE=-103, SQLSTATE=42604, SQLERRMC=255044462d312e330a25c7ec8fa20a352030206f626a0a3c3c2f4c656e677468203620, DRIVER=3.50.153
JDBC Message processing failed, due to Error processing request in sax parser: Error when executing statement for table/stored proc. 'DBDPUSER.pdf' (structure 'STMT'): com.ibm.db2.jcc.b.nm: DB2 SQL Error: SQLCODE=-103, SQLSTATE=42604, SQLERRMC=255044462d312e330a25c7ec8fa20a352030206f626a0a3c3c2f4c656e677468203620, DRIVER=3.50.153
</ERROR>
Can anybody tell me how to resolve the problems?
And tell me about how to deal BOLB column using PI.
Best Regards
TerryHi Terry Qin,
I understand, you are getting below XML from sender JDBC channel. But when you getting SAX parser error, in receiver JDBC.
<ns:DT_PDF_Req xmlns:ns="http://XXXXX.com/sap/xi">
<row>
<ID>1</ID>
<PDF></PDF>
</row>
</ns:DT_PDF_Req>
I think it is because the XML which is going to receiver JDBC channel is not well formed (because pdf can containg < & characters).
You can achive this sceanrio, by selecting receiver JDBC channel as Message Protocol "Native SQL Format" [Link1|http://help.sap.com/saphelp_nwpi711/helpdata/en/44/7c24a75cf83672e10000000a114a6b/frameset.htm] you can send non XML to receiver channel.
Before that, you have convert above input XML into SQL statement, using Java Mapping.

How to display Rows as Columns in JSF?
I am using dataTable component to get data for my Menu, i have one column in it which returns me the data, because its automatically adding <tr> and <td> tags to it, its showing data in tabular form.
I want to show output Horizontally instead of Vertically the way its showing.
Is their any way i can display Rows as Columns?
Code:
==============================================
<div class="bodyarea">
<div id="location">
<h:dataTable value="#{menuItem.breadCrumb}" var="bread" >
<f:verbatim><ol></f:verbatim>
<h:column>
<f:verbatim><li></f:verbatim>
<h:outputLink id="crumbID" value="#{bread.menuLink}">
<h:outputText id="crumpName" value="#{bread.menuLabel}"/>
</h:outputLink>
<f:verbatim></li></f:verbatim>
</h:column>
<f:verbatim></ol></f:verbatim>
</h:dataTable>
</div>
</div>
Thank youTable is not the html element for you, in this situation.
I would use a dataList component (distributed with myfaces implementation).
dataList is able to return a list of item, and using css you will be able display in a horizontal grid. (otherwise you can use layout="grid" in dataList).
Anyway...my impression is that who made JSF was not really understanding how a html programmer like to write his code.
Why do JSF gives us only the possibility to write list of items throught tables?
Why do JSF prints error messages throught tables?
Why div is not a standard component?
This is an incredible lack...
I see also other incredible lasks...but they don't concern html ;) . -
How to display 3 month columns and YTD column
Hello,
I need a help. My report layout requires to display the data in 3 dynamic month columns and one Fiscal year Year-to-date column for a period of time. For example, ending month is FEB:
Items : DEC : JAN : FEB : FY YTD
A : $10 : $11 : $12 : $100
B : $1 : $2 : $3 : $10
(Note: FY YTD is the total sum from OCT to FEB (5 months), not 3 months to be displayed)
I tried to create a query and use Matrix with group, but the report always display five (5) month columns
from OCT to FEB instead of displaying three (3) month columns. If the query is limited to display
three months as desired, then the total sum will be 3 displayed months only (instead of 5 months).
How to create a query or how to display three months and FY YTD or do anything else with Oracle Builder9i?
Thanks,You could use the DECODE function and variables
i.e. have a four column report
in your query use somthing like
, decode(period,:P_PERIOD1,1,0)* amount as period1
, decode(period,:P_PERIOD2,1,0)* amount as period2
, decode(period,:P_PERIOD3,1,0)* amount as period3
, amount as ytd
In your before report trigger poulate the variables with your required values -
How to perform calculations using column data in BI Publisher
Hello guys
I am very new to BIP, and recently I am learning to create new templates using XML files..
I am trying to create a report that has Account Amount, Amount Net Amount, PM_Amount and a New field say "X"
For Account Amount it is what it is, but for Net Amount it is "Account Amount/40%", for PM_Amount it is "Net Amount x (Account Amount/30)" and for field X it is "(Net Amount + PM_Amount)/column A" where column A is another data field in the XML file but it should not be included in the template report..
Could anyone help me with how to perform such kind of calculations in BIP Template builder? In OBIEE, it is very easy that I can just use column formula, but in BIP I still haven't figure out the way yet..
PLease advice
ThanksThanks for the reply..
I looked at the link you provided already, what I wanna know is how to exactly apply the expression in my calculation. In other words, I know that Column C = "Column A div Column B", but in BIP form property, how do I actually substitue "column A" with the actual column..
I wish I could post the XML, but it is huge, it contains 6 data sets and more than 100 columns. I only need 15 columns on my template.
On the form property of each measures, in the "advance tab", I see codes like <?accountamount?>. Now I wanna have a new column said "PM_Amt" which should be "(accountamount div %40) x column B". So I just randomly select another column said "payment". I rename it to "PM_AMT" and on its "advanced tab" it is still <?payment?>. So right there, if I wanna replace that code with a new one that does "(accountamount div %40) x column B" calculation, how would I do it? What would be the syntax including how to propertly refer to the right column field as part of the expression?
And do I have to always use xdofx between <>? how would I know?
Please advice if you understood what I am trying to say
Much thanks

How to display Formatted text in adobe form
In adobe form, I want to display the text which is inputed by formatted text edit in WD ABAP application.
It is always displayed as plain text like '<p>this is test text.</p>'. I have set the attribute Data Format to XHTML, Field Format to Rich Text for the Text Field in adobe form. But it doesn't work.
How to display these formatted text?
Thanks and Best Regards,
JunHi Juergen,
I found Your blog and found it really interesting... though I was not able to use it: I (like Jun Li is asking, I guess) need to use a dynamic text, containing formatting informations (according the xhtml syntax).
I tried to pass it to the form by an ABAP-dictionary based interface and by means of the context (in a webdynpro page), but both tries failed.
Some suggestion will be greatly appreciated.
Thankyou

How to display metadata such as data load date in answers report title?
We have a requirement to display the last load date of the data relevant to the report the user is viewing. We have such information stored in a metadata table listed by the fact table the report is referencing. Our proposed solution is to create new answers reports off of this metadata table and put each report (with the appropriate filter on the fact table) on each dashboard section where the corresponding report is placed. One problem with this approach is the load date information will not be reflected in the print form of the report as the date is dashboard content - not report content. Is there any way to overcome this situation (other than create a ton of variables specifically created for this purpose)? I'm open to entertaining javascript ideas, if necessary. I would love to know how to push this OBIEE envelope further. Thanks in advance.
Hi,
I discuss with some people who are familiar with SharePoint, we both thought Windows Explorer may
not accept the custom metadata.
if we want to do some customization, it is recommended to ask for help in development forum.

How to reset values in a Data Form Bean?
I have created an ADF application that has a search facility in it. The architecture is as follows:
DataPage (search.jsp) --> DataAction (validateSearch) -->DataAction (refreshCollection) --> DataPage (results.jsp)
I have successfully created a data form bean to hold the data that is submitted in the search and bind it to the refresh method of the collection. I have also successfully overridden the validate method, which catches and throws and displays appropriate ActionErrors on the search.jsp page.
I have added a link back to the search.jsp page from the results.jsp page (as a user may wish to perform another search), the ActionErrors are resetting ok but I have not managed to work out how to reset the values of the actual data form bean.
I have tried several different ways of overriding the reset method within the data form bean but so far have been unsuccessful - I would appreciate any assistance with this matter.
Shown here is a basic example of a form bean that I have been trying different things out with - I can not get the reset method to even be called - please help!
package uk.dmf.eg02;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
public class searchForm extends ActionForm
String search;
public setupForm()
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
ActionErrors errors = new ActionErrors();
if (search.trim().length()==0)
errors.add("search", new ActionError("error.search"));
return errors;
public void reset(ActionMapping mapping, HttpServletRequest request)
System.err.println("EXECUTING RESET METHOD");
this.search = "";
public void setSearch(String search)
this.search = search;
public String getSearch()
return search;If you run in request scope the reset method is called, however in session scope is't only called once (or never?). See documentation of method reset():
public void reset(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request)
Reset bean properties to their default state, as needed. This method is called before the properties are repopulated by the controller.
The default implementation does nothing. In practice, the only properties that need to be reset are those which represent checkboxes on a session-scoped form. Otherwise, properties can be given initial values where the field is declared.
If the form is stored in session-scope so that values can be collected over multiple requests (a "wizard"), you must be very careful of which properties, if any, are reset. As mentioned, session-scope checkboxes must be reset to false for any page where this property is set. This is because the client does not submit a checkbox value when it is clear (false). If a session-scoped checkbox is not proactively reset, it can never be set to false.
This method is not the appropriate place to initialize form value for an "update" type page (this should be done in a setup Action). You mainly need to worry about setting checkbox values to false; most of the time you can leave this method unimplemented. -
How to display a Report 9i from Forms if the Report has a Parameter Form?
Hi,
could some one please post me a code sample to show how to call a (paper layout, RDF) Report from Forms if I would like it to display the Report's parameter form first?
Thank you in advance.
Tamas Szecsy
I used the following code segment do achieve the job, but I get "REP-546: Warning: The value of restricted LOV parameter P_ALAL is not among the selectable values" message, even though I would like to specify the P_ALAL value on the report's parameter Form.
declare
paramlist_id ParamList;
tmp_riport_name varchar2(200);
report_id report_object;
report_job_id varchar2(200);
tmp_id number;
begin
-- init
tmp_riport_name := null;
-- parameter list
paramlist_id := get_parameter_list('mytmp_params');
if not id_null(paramlist_id) then
destroy_parameter_list(paramlist_id);
end if;
paramlist_id := Create_Parameter_List('mytmp_params');
add_parameter( paramlist_id, 'PARAMFORM', TEXT_PARAMETER, 'YES' );
-- call report
report_id := find_report_object( 'DUMMY' );
if report_id.id is null then
return;
end if;
-- display
set_report_object_property( report_id, report_execution_mode, runtime );
set_report_object_property( report_id, report_comm_mode, synchronous );
set_report_object_property( report_id, report_destype, 'preview' );
set_report_object_property( report_id, report_desformat, 'PDF' );
set_report_object_property( report_id, report_server, 'rep_geoias' );
set_report_object_property( report_id, report_filename, :ALAP_REPORTS_NAME||'.rep' );
report_job_id := run_report_object( report_id, paramlist_id );
tmp_id := to_number(substr( report_job_id, length(name_in('rep_geoias'))+2 ));
web.show_document( '/reports/rwservlet/getjobid'||tmp_id||'?server=rep_geoias', '_blank' );
END;I think you specified report object name incorrect.
in command line:
repid := FIND_REPORT_OBJECT('REPORT1');
Report1 must be name of report object in Form Builder.
However to call report from Oracle Form you must do more work. For example:
- Create report server name
- Adding some code to set property for report object base on report server you created.
Cheer!
