Changing database field in jsp

Hello
I have a database table which i want to display in a jsp page. I can get this far but what i want is the table printed with the option of changing individual values of one of the fields i.e change one field in a paticular row. Could anybody let me know how i could approach this please. I am using servlets for DB access.
many thanks
john

Unfortunatey i havent started yet. I have so far created a servlet which accesses a mysql DB passes the results to a jsp page and displays them in a table. This works fine. What i want to do now is create a second jsp page where an adminstrator can change the value of the last field for any paticular row. whether this info should be displayed in a form or table i dont know.thinking about it maybe i can populate a form with an individual DB row with the option of changing the last field in the form. does this sound like it might work or has no one got a clue what i am talking about.
thanks

Frm-40208 from running in query mode. cannot change database fields

Hi,
Could some one help me with this.
I am calling a form from another form. I am passing the parameter list to the calling form and doing a query by setting the block property. But when queries the message
FRM-40208 Form running in query mode. cannot change database fields .
I do not want the message to appear when they go the called form . Please some one could help me how could I avoid displaying the message.
Regards
Bain

Hi,
Good day! I am working with a module that also calls another form. It uses call_form with query mode parameter set to query_only. My problem is, whenever i call the other form using the call_form, it would display the called module and then as it populates the detail block of the called form, it will display frm-40208 from running in query mode. cannot change database fields per record. What I want is for the message to be displayed only once.
I have tried capturing the error by using on-error trigger, but it doesn't go to that whenever the other form was being called. I think the message has to do with the post-query trigger, because it passes some values on a dbase block objects.
Do you have any suggested solutions or workarounds to make the message display only once whenever the other form is being invoked by the call_form?
I would greatly appreciate any suggestions/ideas.
Thanks and regards,
ASantiago

FRM-40208: Form running in query-only mode. Cannot change database fields.

Hi,
I am using forms 6i where it is calling a form from a menu in query like call_form(,query_only). Now an error is occurring on call of that form ‘FRM-40208: Form running in query-only mode. Cannot change database fields.’ Though this is been handled to give a certain message from on_error message from a package from library.
Now the issue is that the error keeps on popping even after the ok button is pressed. There are number of records from the table. How can we handle the error. Any suggestion would be really appreciated!!!
Regards,
Rajesh

thanks Gred but i have resolved the issue. it seems that each row was going into query_only mode (program written such a way). therefore the error was showing even after the OK button. handled the issue from ON_ERROR trigger. anyway thanks for your time Gred!

Sending colour from a JSP page into a MySQL database field

Dear All,
I am working on trying to send different colours into a MySQL database field from a JSP page.
This is so that I can represent different pieces of data on my webpage tables in different colours providing status depending on the user request.
What is the best way to write JSP code for this?

Update sql server database field of type datetime using jsp

I'm working in a jsp applicaion which use SQL server 2000 as database. I need to update database field with current time, so I used a bean for that in which I used following method:
public java.sql.Time getSqlTime(){
Calendar cal=Calendar.getInstance();
cal.setTime(new Date());
java.sql.Time sqlTime=new java.sql.Time(cal.getTime().getTime());
return sqlTime;
when I print the time on a page using this method works properly, but I update a database field of type datetime, it takes correct time but updates with '01/01/1900 12:26:46 PM' like that. I need only time , how can I correct this?
Thank you

public java.sql.Time getSqlTime(){
Calendar cal=Calendar.getInstance();
cal.setTime(new Date());
java.sql.Time sqlTime=new
java.sql.Time(cal.getTime().getTime());
return sqlTime;
}to get the Time for current time, you can just simply do
java.sql.Time sqlTime = new java.sql.Time(System.currentTimeMillis());I dun know about SQL server 2000... but thinked that you should declare you
field as time rather as datetime.

Is there any way to change a field as database item dianamically ?

Is there any way to change one field as databas item dianamically ?
We are using two fields. Depending on a specific condition we have to change one field as database item and other as non database item. and vice versa. Help me Please......

This is because we use OLE. in a specific condition we use MS Excel and in other condition we have to use MS Word. But it stores in to one field.........Thats why ......

Changing databases from MS SQL Express to MySQL in a Report at runtime

Hi all,
I have an issue in changing databases from MS SQL Express to MYSQL or vice versa in a Report at runtime.
Here is what I do:
I create a very simple report with the Crystal Report Designer 2008 V 12.3.0.601.
This report uses a stored procedure to retrieve it's data. I connect to the Database with JDBC.
I have two Databases with similar schema and procedures: MS SQL Express an MySQL.
When I create the report with MSSQL all parameters have the '@' character, as they are named. ok.
I deploy this report in a JSP application with the crystaldecisions SDK an show it in html viewer format.
The connection to the MSSQL DB gets established by my JSP and the CRJavaHelper.
I pass the parameters through my URL to the JSP and finally to the CRJavaHelper (addDiscreteParameterValue)
and everything works fine.
The challenge starts, when I try to change the Datasource of this report to MySQL at runtime (which is a requirement in my project).
I successfully can establish the DBConnection, but my stored procedure just doesn't get called!
The report just displays totally empty, no Exceptions etc. are thrown. In the DB logfile I see the effort to find my procedure
and that's all. The Statements called by the SDK finds the correct Procedure, but there's no call to the procedure.
Of course I know, that MS SQL names it's procedures slightly different (';1' at the end), but even when I rename the table Alias to the correct name in CRHelperJava, I get no call to the procedure in MySQL. I also renamed the parameter-fields in changeDataSource(..) by casting the table to IProcedure and working on its methods. Still no success.
What am I missing to do or what do I do wrong?
Any suggestions or even solutions?
Best Regards,
Tom

after all I have managed to set param Values, now I'm stuck because the parms seem to have dissappeared in the formula fields. E.g. I receive this Exception:

How to change the fields in a JSF form based on a URL parameter

I am trying to build a generic JSF form of parameters which I want to dynamically change (i.e.
change which field is visible, what the label text should be, etc) based on a URL parameter.
I can set the fields using logic in the backing bean as an action on a command button pressed.
But how do I do it based on the URL parameter ? I can retrieve the URL parameter but I
don't know where to put (or hook) the Java code to do this initialization prior to
the page being rendered for the first time.
The fields in the JSF is being configured dynamically using a database table.
BTW I am using Jdeveloper 10.1.3.5
Thanks
CK

Thanks. I decided to set a Session bean to store the value of the URL parameter (if it is set)
and then to use the session bean to initialize the attributes of the fields on the JSF Page.
There also seems to be some caching of the inputText fields (i.e. it reverts back to the first
initialized value) even though I tried to change it using the URL parameter in the requestScope
backing bean. So, setting the values into the Session bean and retrieving it back from there
seems to be more reliable.

Field Explorer help, not all Database Fields available

Greetings all, I'm new to Crystal Reports (version XI by the way) and Tigerpaw. I've had some great luck editing existing reports to the specifications we've needed thus far. But now I've run into a real problem, it seems small, but it's important to me.
The one change I'm unable to accomplish on our new invoice report:
-Adding the Tigerpaw field, Account Name, to an invoice. The "Account Name" field is a field pulled from the tblAccounts Database Fields category in the Field Explorer. But when I'm in my invoice template, I do not have that category available, I only have tblSysListViewPrint and tvwr_Invoices categories, the latter does have the field for "Account ID" which is close for our purposes, but not the same. So how might I go in and pull from the tblAccounts category...specifically to get the tblAccounts.AccountName field. Copying that field from another existing report does not work either, "one or more formulas fail to compile".
I'm not sure how it decides what Database Fields to pull from, because on other reports, the tblAccounts category is available, but not the tvwr_Invoices category, so I am quite confusedl.
Hopefully this makes sense to someone out there.
Thanks.

Thanks, V361,
When I go to create a blank report, I get no databases available. My first prompt is the "Database Expert". The "available data sources" list is Current Connections (no items), Favorites (no items), History (no items), and Create New Connection. The "selected tables" list on the right is blank. I honestly don't have a clue how connect to whatever server contains those items. I realized since I first posted that I need to figure that out to make any progress. All the created reports already have the database field categories set up already, but it looks like all the available fields were not initially chosen for the reports.
So what I believe it comes down to is the fact that I need to figure out how to "Create New Connection" to find my available database fields.

Passing Changed extended fields using ALE-IDOC to receiving system

Hi all,
Please tell me how passing changed extended fields using ALE-IDOC to receiving system can be achieved. Is it possible by Chnage pointer concept.Do i need to do some coading after data enters into receiving system as it is required while creating the entries in database table.
For ex. in matmas05 extended for classification and inspection view and then created using 'CREATION'
related bapi.Do i also need to incorporate the changes by change related bapi or ir can be handled by change pointer concept.
Thanks.

Hi Sanu
1) Please tell me how passing changed extended fields using ALE-IDOC to receiving system can be achieved. Is it possible by Chnage pointer concept.
=> Looks like you have extended standard IDOC here. so you need to find User Exit or BADI for the Push program to populate the additional fields. Yes, it is possible thru change pointers as well.
1) Do i need to do some coading after data enters into receiving system as it is required while creating the entries in database table.
=> Yes, as suggested in 1 try finding User Exits/BADIs.

Changing a field based on another field

hi one and all
i am looking for a way to change a field based on another field. if i have item 2 and item 8 on the page and item 8 needs to be required based on item 2 based on a requirement, how would this be done.
ex if item 2 has a PO inputed, when it is moved off the field, item 8 should be changed from required false to required true. i have tried in both the process request and process form request with no luck
any suggestions.
thanks

hello again
after your input and after reviewing the tutorial ( which i accomplished based on data from a table but not a field ) , i did the following and have been fighting it for a day. am i doing this correctly
on the itemid OrgRptCode1 i changed the action type to firePartialAction and the event is name o1
then i added this code to see if the action would fire
if (pageContext.getParameter("OrgRptCode1") !=null) // either line will be commented out
if (pageContext.getParameter("o1") !=null) // either line will be commented out
System.out.println("Field is not empty");
else
System.out.println("Field is empty");
am i missing a step . also
when i enter the page i get Field is empty. when i enter the field and tab off i get the error page w/ this msg

Automatically populate fields in jsp documents based on other fields

hello guys. I have a jsp document
that has the following
<af:inputText value="#{bindings.SourceDocumentId.inputValue}"
label="#{bindings.SourceDocumentId.label}"
required="#{bindings.SourceDocumentId.mandatory}"
columns="#{bindings.SourceDocumentId.displayWidth}"
binding="#{backing_transactions_editTransactions.docId}"
id="docId">
<af:validator binding="#{bindings.SourceDocumentId.validator}"/>
<f:convertNumber groupingUsed="false"
pattern="#{bindings.SourceDocumentId.format}"/>
</af:inputText>
<af:inputText value="#{bindings.DocumentName.inputValue}"
label="#{bindings.DocumentName.label}"
required="#{bindings.DocumentName.mandatory}"
columns="#{bindings.DocumentName.displayWidth}"
binding="#{backing_transactions_editTransactions.docName}"
id="docName">
<af:validator binding="#{bindings.DocumentName.validator}"/>
</af:inputText>
And I have created the generated the backing beans automatically.
public class EditTransactions {
private CoreInputText docId;
private CoreInputText docName;
public CoreInputText getDocId() {
return docId;
public void setDocName(CoreInputText inputText7) {
this.docName = inputText7;
public CoreInputText getDocName() {
return docName;
I have a method in appmodule that has this
public String getDocName(Number docId)
{String docName;
return docName
on the document Id field I have to input a certain docId after I input the docId I have to populate automatically the docName based on the doc Id being given.
question
1. how can I set the document name automatically w/out submitting the page ?
2. how can I use my backing bean to set the docName using the method in my AppModule.?
Can anyone help me regarding this one.
Thank in advance
alvin.

A: automatically populate fields in jsp documents based on other fields

here is what you need to do:
1. Change the definitions for your fields as following
<af:inputText value="#{bindings.SourceDocumentId.inputValue}"
                        label="#{bindings.SourceDocumentId.label}"
                        required="#{bindings.SourceDocumentId.mandatory}"
                        columns="#{bindings.SourceDocumentId.displayWidth}"
                        binding="#{backing_transactions_editTransactions.docId}"
                        id="docId" valueChangeListener="#{backing_transactions_editTransactions.docIdChange}"
autoSubmit="true">
            <af:validator binding="#{bindings.SourceDocumentId.validator}"/>
            <f:convertNumber groupingUsed="false"
                             pattern="#{bindings.SourceDocumentId.format}"/>
          </af:inputText>
          <af:inputText value="#{bindings.DocumentName.inputValue}"
                        label="#{bindings.DocumentName.label}"
                        required="#{bindings.DocumentName.mandatory}"
                        columns="#{bindings.DocumentName.displayWidth}"
                        binding="#{backing_transactions_editTransactions.docName}"
                        id="docName"
partialTriggers="docId">
            <af:validator binding="#{bindings.DocumentName.validator}"/>
          </af:inputText>2. add the followig method to your backing bean:
public void docIdChange(ValueChangeEvent valueChangeEvent) {
    getDocName().setValue((String)getDocId().getValue() + "suffix");
}Run your form and enter the value into docId field, then press tab to go to the next field - docName will be populated

How do I get a value from a portal form for a non database field ? HELP!!

I have a form based off of a table that I added a field to. The form is to allow the user to change abbreviation for a
department field ie. BIO to BIOL. for a biology department. I have a pl/sql procedure for validation using the custom option
on the update button to verify the user and update the data. I have tested to code at the sql prompt and it works.
They only difference between the prompt and the form is the non-database field new_dept_abbr was added to the
form. I don't know how to capture the value of the user input into a variable that can be used in the pl/sql.
Any help would be appreciated.
I have tried this approach
v_new_dept_abbr := p_session.get_value_as_varchar2(
p_block_name => 'default',
p_attribute_name => 'new_dept_abbr'
have tried using p_attribute_name as 'a_new_dept_abbr' but this does work and does not exist in the body of the form.
Have also tried setting the p_block_name to _session - still doesn't work.
Any ideas??
Thanks
Debbie Brennan

Thanks for the info. I tried that and it still doesn't pull the value. I have opened a TAR via metalink, but I'm not getting any
satisfactory answers. I ran across an note - 137172.1 that has this snippet of information in it.
Unfortunately, at this time (portal 3.0.7.6.2) , a non-table item cannot be
referenced in a plsql event handler, only in client side JavaScript code. This
is a known limitation and will be fixed in a future release.
I don't know how to get the value from the client side JavaScript code to a pl/sql variable. Do you?
I've been trying to get them to tell me if the 'known issue' has been addressed in 3.0.9.
I'll keep at it. Thanks so much for your suggestion I appreciate it.

Changing the field name at runtime in rpt file

Hi everybody
I'm using C# and Crystal Report XI (Deverlop license) to develop windows application in VS.net 2003.
Please help me to change the field name of the bounded column of Crystal report file at the runtime.
(In some case client's database had changed the structure as fieldname, fieldtype. Then they request a utility to change the field names in the .rpt file programmatically )
Thanks

That's fine but still i want to prefix the schema name within the .sql file. My .sql should contain the name of that parameter only as i want to get that parameter replaced by the schema name at runtime. Some other users are using the same .sql file and they have access to that specific schema only. i want to make the .sql file more general so that it can be used by everyone without altering it every time.Sorry, your requirement no longer makes sense.
If people have to access a specific schema because they need the script for general use, then you will have to hard code the schema name into it.
If the script is to prompt for the schema name and connect to that schema and then use that schema name inside the called sql script, then people would not be able to use it generically, as it would be reliant upon the schema name being passed in.
It sounds as if you're trying to write one generic thing that needs to do two different tasks.
Just have two scripts and make life simple.
