How to pass a java variable to a JSP custom action?

I am trying the following code to display a list of 5 choices. But it shows me choices as <%= i %> and not the actual values of i as 0,1,2,3,4.
what's going wrong?
<body>
<form>
<test:SearchList name="testList" listSize="5" listWidth="300" multiple="Y" >
<% for(int i=0; i< 5; i++){%>
<test:SearchListOption label="<%= i %>" value="<%= i %>" />
<%}%>
</test:SearchList>
</form>
</body>
</html>
thanks-

Hi,
Thanks for reply.
Oh I guess by mistake I sent part of code for the jsp file which in full is as :
<%@ taglib uri="/WEB-INF/tlds/taglib.tld" prefix="test"%>
<html>
<body>
<form>
<test:SearchList name="testList" listSize="5" listWidth="300" multiple="Y" selectList="" >
<% for(int i=0; i< 5; i++){%>
<test:SearchListOption label="<%= i %>" value="<%= i %>" />
<%}%>
</test:SearchList>
</form>
</body>
</html>
and here is the taglib.tld code.
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"

How to pass a JavaScript variable into a java method

I would like to know how to pass a JavaScript variable into a java method with in a <% %> tag inside a JSP file like so:
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<script LANGUAGE="JavaScript">
myValue = someDynamicValue;
<% System.out.println(myValue)%>
</script>
</head>
<body>
</body>
</html>
obviously "System.out.println(myValue)" will not work because myValue is seen as a java variable and not a JavaScript variable.
I would like to know how to let the jsp file, that I wrote in the above code, see myValue as a JavaScript variable and not a java variable so that I can pass it to a java method.
NOTE: the java method does not have to be a println() method, it can be any method of my choice.
NOTE: someDynamicValue is a JavaScript value that can dynamically change

I don't believe you can. JSPs are really just elaborate templates that an engine such as Tomcat parses and generates an HTML page based on. That page is then displayed to the user. By the time you want to use some function in Javascript, the JSP has already been parsed and generated.
Basically, Javascript and JSPs can't talk to each other. One's server-side and the other is client-side.

Passing a variable from Javascript to java variable in a JSP.

Here is simple test Ive been messing around with.
How do I assign the value that was selected in the radio button to a java variable in my JSP here. Javascript being client side and JSPs being serverside makes this difficult.

Thanks dudes.

Please excuse me for appearing dim but my JSP skills are rather weak.
I dynamically create rows in a table from an Iterator. If the mainTopic is news then I need a third column to appear with radio buttons. I have all this done. When a radio button is selected and the UPLOAD button is selected I need to know which of the values in the table was selected.
When I ran the test below the selected value was null. Can you help me?
Thanks.

How can we use java variable in javascript code on JSP page?

How can we use java variable in javascript code on JSP page?
Pls help

Think about it:
JSP/Java is executed on the Server and produces HTML+JavaScript.
Then that HTML+JavaScript is transfered to the client. The client now interpretes the HTML+JavaScript.
Obviously there's no way to access a Java variable directly from JavaScript.
What you can do, however, is write out some JavaScript that creates a JavaScript variable containing the value of your Java variable.

How to pass the USER variable to RPD in 11g?

I am trying to figure out how to pass the USER variable to the RPD in 11g.
In 10g, I had define an intializtion block to store the USER variable and pass it to a statement that has to be executed before the query is executed.
We use the Oracle VPD technology that allows to restrict data access. This is the statement that has to be executed before a query can run.
select vpd_adwh.setclnvpdcontext_fnc('VALUEOF(NQ_SESSION.cuser)', UPPER(:USER))) from dual
That is the 10g version and it works fine.
In 11g, I tried to use
select vpd_adwh.setclnvpdcontext_fnc('VALUEOF(NQ_SESSION.cuser)', UPPER('VALUEOF(NQ_SESSION.USER)')) from dual
but this is not working.
Any help?

any ideas?

How to pass Unix environment variable to a SQL procedure or SQL * Plus

Can any body suggest me how to ,
How to pass Unix environment variable to a SQL procedure or SQL * Plus file..
I am trying to invoke a SQL Procedure from Unix
by passing the value of a Unix environment variable.
Is it possible..?
Thanks in advance.
Regards,
Srinivas Jaltaru

Within your shell script you can use what is known as a "here document" which is basically a way of wrapping a call to Oracle. The following call to Oracle loops and writes rows to files with numerically increasing file names. Two unix shell variables are used, one in a select statement and one in a spool command :
<pre>
#!/bin/bash
export ORACLE_SID=DEV05
FILENO=1007351
while [ ${FILENO} -le 1008400 ]
do
FILENAME=farm_${FILENO}.txt
DUMMY=`sqlplus -s user20/user20 <<SQLSTOP
set lines 73
set pages 0
set head off
set termout off
set echo off
set feedback off
select rpad(searchx, 8)
from blastx@PRODUCTION
where searchx = ${FILENO} ### here's a shell variable
spool /export/home/user20/sql/psiblast/BACKUP2_D/${FILENAME} ### here's a shell variable
spool off
SQLSTOP`
FILENO=`expr ${FILENO} + 1`
done
exit 0
</pre>

How to pass values to variables in WAD 7.0 using java script

Hi.,
My requirement is based on WAD 7.0.
The sales value has to displayed in WAD using graph with various chart types.
I have created variables for plant and material group in a query.
I have created drop down box for plant with all plants in it, check box for material group and a Submit button in WAD in FORM tag of HTML coding.
Once all the values are set in drop down box, checkbox and if the user clicks on submit button, the values has to captured by the variables for which I have created and the graph has to be aligned to the new values in variables.
Kindly help me how to use java script to get the values from FORM and pass it to variables.
Regards,
Selva

Hi Selva,
You do not need to use Javascript for this. Instead you can achieve this by using API Commands in WAD 7.0.
Please configure Action on the ButtonGroup webitem to use 'Commands'.
->Choose Command 'Set Variables Values / SET_VARIABLES_STATE' under Commands for Web Templates
->Set Display Variable Screen setting to OFF
->Choose Query Variable for Plant, Select Variable Type as 'Binding Type', Binding Type as 'Data Provider Selection', Data Provider as the one you have assigned to the Dropdown webitem, Characteristic as 0PLANT or as that assigned to the Dropdown webitem
->Repeat above steps for Query Variable Material Group
Now when you make a selection from the Dropdown webitems, the Chart output will change accordingly. Let me know if this helps.

How to pass Applet form variables without showing it on top ?

If I use URL method then all are getting displayed on URL location of browser which I do not want. I want to pass many form variables to another .asp file, so it may not be good also.
What is the best way of doing it ? Need urgent help about it.

Well If you create a POST request instead as a GET request the variables will not show up in the URL.

How To pass a period variable

Hi experts!
I have a model in visual composer that calls a query which has a filter on the characteristic 0FISPER, when I execute this query in the query Designer, the period of fiscal year is asked in the format "009.2007 - 008.2008".
The problem is that I don't know how to pass this value in VC, because if I indicate the static text "009.2007 - 008.2008" in the field "Fiscal year period" in the connector between the inputform and the query, when I execute the VC model the following error appears:
"Nested Exception. Failure to execute native function. Nested Exception.
INVALID_VARIABLE_VALUES"
Do you have any idea how to pass the values of the period to the variable of the query??
Thnks in advance!!!

How to pass a shell variable to rman scripts

I want to backup datafile to different directory
depending on the current time,and I can do this to
pass a shell variable to rman scripts,and this
variable will used as part of format ,like this:
backup incremental level=0
tag rman_inc0_bck
filesperset 5
format '$(DIR)/rman_fulldb_%u_%s_%p_%d'
(database include current controlfile)
and $(DIR) is shell variable ,but rman will not
recognize this ,how to achieve this?

You could send your script to rman thru a pipe | or <<
echo "backup incremental level=0
tag rman_inc0_bck
filesperset 5
format '$(DIR)/rman_fulldb_%u_%s_%p_%d'
(database include current controlfile);" | rman target /You could also create a "temp script" and then use it from rman with cmdfile
sed "s,XXXDIR,$(DIR)," yourtemplate > /tmp/rmanscript.$$
rman target / cmdfile /tmp/rmanscript.$$
rm /tmp/rmanscript.$$

I'm using portal eventing to pass a variable to a BW template. While I can pick up this value using javascript, I do not know how to pass it to the query.
Let me just say, I am new to BEx, so any guidance you could give me would be most welcome.
Thanks in advance,
Liz.

Hi,
Perhaps this JavaScript can help?
document.appletName.getQueryObject().setParam(1, param value);
Call this peice of code on some event, for example the click event of a Button.
There are many more examples on this forum, search for more.
Regards,
Michael
