Use web bean problem

I work with BusinessComponent and DataWebBean for create JSP page.
I want change the whereClause at run time for the View Object as code:
<jsp:useBean class="oracle.jbo.html.databeans.NavigatorBar" id="nbc" scope="request" >
<%
nbc.setShowNavigationButtons(true);
nbc.setReleaseApplicationResources(false); nbc.initialize(pageContext,"bcPackage_BcPackageModule.DeptView");
nbc.render();
%>
</jsp:useBean>
<jsp:useBean class="oracle.jbo.html.databeans.RowSetBrowser" id="rsb" scope="request" >
<% rsb.setUseRoundedCorners(true);
rsb.setShowCurrentRow(true);
rsb.setVisibleRows(10);
rsb.setAlternateColors(true);
rsb.setShowRecordNumbers(false);
rsb.setReleaseApplicationResources(false);
rsb.initialize(pageContext,"bcPackage_BcPackageModule.DeptView");
rsb.getRowSet().getViewObject().setWhereClause("DeptNo=20 ");
rsb.getRowSet().getViewObject().executeQuery();
rsb.render();
%>
</jsp:useBean>
Afther this operation, the NavigatorBar don't respond correctly (if I go next and then go prev it fails)
idem with:
<jsp:useBean class="oracle.jbo.html.databeans.NavigatorBar" id="nbc" scope="request" >
<%
nbc.setShowNavigationButtons(true);
nbc.setReleaseApplicationResources(false);
rsb.getRowSet().getViewObject().setWhereClause("DeptNo=20 ");
rsb.getRowSet().getViewObject().executeQuery(); nbc.initialize(pageContext,"bcPackage_BcPackageModule.DeptView");
nbc.render();
%>
</jsp:useBean>
<jsp:useBean class="oracle.jbo.html.databeans.RowSetBrowser" id="rsb" scope="request" >
<% rsb.setUseRoundedCorners(true);
rsb.setShowCurrentRow(true);
rsb.setVisibleRows(10);
rsb.setAlternateColors(true);
rsb.setShowRecordNumbers(false);
rsb.setReleaseApplicationResources(false);
rsb.initialize(pageContext,"bcPackage_BcPackageModule.DeptView");
rsb.render();
%>
Where's the problem?
Thanks you
Andrea

Using web beans in JSP

I would like to know how create a tree using Web Beans that Jdeveloper provides. Using the web object editor I could add two Beans which mapped to JSTree and JSTreeData(in oracle.jdeveloper.jsp.wb package), though I don't know the difference between them. I tried to include Both these beans in the JSP(which appear as tags) but I am unable to render the tree. Let's say I have a parent node (text: row1, url: url1, 3 childs) and 3 child nodes (text: row2..row4, url: url2..url4, each with no childs). How do I write it in the JSP to render it properly

How to clear/delete previously instantiated web beans?

Is there a way to flush out all the previously used web beans that were created programmatically in the CO?
In my earlier version of the CO, I had used a webBean.addIndexedChild(MessageTextInputBean), to add create a text input field on the fly at the Page Level.
I have since then, revised my CO code to create a table bean and then create the MessageTextInputBean within the table bean. However, for some reason, I am now seeing duplicate tables (i.e. two instances) of the table on my page.
I have tried all the following but none of these attempts have been successful in removing the older web bean that still seems to be lurking around:
1) vo.clearCache()
2) vo.reset()
3) am.clearVOCaches
4) am.resetState(true)
5) bounced apache (even though I'm running the page locally)
6) even cloned the current VO and the PG to new names, and ran the new page.
7) cleared IE cache/cookies
8) used webBean.clearIndexedChildren() - This one removes everything (all declaratively defined items) but keeps the original Web bean. Opposite of what I'm trying to achieve.
Any idea on what could be going on?

Data web bean (chart) using a dynamic view object

Please I want a quick help. I read all forums concerning this subject but I still couldn't do it.
- I create a view object which takes a proameter using the ? style parameter.
- I passed the parameter from an html page and execute the query
of the view as follows:
<%
String deptno = request.getParameter("deptno");
if(deptno != null) {
oracle.jbo.html.jsp.JSPApplicationRegistry.registerApplicationFromPropertyFile(session , "MyProject21_package3_Package3Module");
oracle.jbo.ViewObject v = oracle.jbo.html.jsp.JSPApplicationRegistry.getInstance()
.getAppModuleInstance("MyProject21_package3_Package3Module",request,session)
.findViewObject("View1");
v.setWhereClauseParam(0,deptno);
v.executeQuery();
%>
- And then I used the data web bean chart as follows:
<jsp:useBean class="oracle.jbo.html.databeans.ChartRenderer" id="ch" scope="request" >
<%
ch.setReleaseApplicationResources(false);
ch.initialize(application,session, request,response,out,"MyProject21_package3_Package3Module.View1");
ch.setCommonScriptName("/webapp/jsp/chart_common.jsp");
ch.getChart().setGraphType(ch.PIE);
ch.setSeriesLabelColumnName("DeptNo");
ch.setDisplayAttributes("CountEmplNo");
ch.getChart().setPieFeelerTextDisplay(0);
ch.getChart().setPieTilt(10);
ch.getChart().setPieRotate(0);
ch.getChart().setLegendDisplay(true);
ch.getChart().setLegendMarkerPosition(0);
ch.getChart().setTitleString("Title");
ch.getChart().setSubtitleString("Subtitle");
ch.getChart().setFootnoteString("Footnote");
ch.setImageWidth(400);
ch.setImageHeight(400);
ch.render();
%>
- I tried to use the View1 as a view name, and the v as a view name
but both of them get the same result
SQL Statement error and the sql statement is displayed with the ? in it which means that he didn't replace it by the parameter.
Please I need quick help.
Thanks.

Using a view-object as a data web bean?

Hi,
When writing JSP pages, I'd like to have a web bean that allows basic data manipulation such as:
- set up a row set - e.g. by specifying a view object and an (optional) where clause;
- navigate this row set (first, next, etc.);
- get or set the values of the attributes of the current row;
- insert, update or delete a row;
- commit or rollback the modifications;
- etc.
This bean should be "silent" - i.e. it would not have to be able to "render" anything - instead, I would use it in <%= bean.method() %> tags, or in <% ...java code... %> sections, in conjunction with other (custom) beans.
I guess I could use a view object - but:
1) How would I have to use it in a JSP context?
2) Or, are there more appropriate objects to do this job?
3) What methods could I use (i.e. where are they documented)?
4) What pitfalls should I be aware of (most notably related to housekeeping after bean use)?
Any information greatly appreciated!
Thanks in advance,
Serge

There are two ways of getting info from the bean.
1) the jsp:getProperty tag, which seems correct in your code
2) the <%= ... tag. In that case you must write a valid java expression. In your case: list.getValue1()

How to use JavaScript in Web bean generated JSP

I want to do some simple JavaScript validations (for example, checking if a particular field is empty) in the JSP page rendered by the data web bean. Because the HTML is rendered by the bean, I'm not able to refer to the HTML controls in the JSP page. I'm not even able to refer to the form with the following standard piece of JavaScript code - "document.forms[0].control_name".
Is anybody aware of how to use JavaScript with these rendered JSP pages?

You just have to add it like and applet , including this line in your JSP or JSF
<script src="http://dl.javafx.com/dtfx.js"></script>Then add the applet
<script>
    javafx(
              archive: "./resources/jar/Draw.jar",
              width: 400,
              height: 200,
              code: "Draw",
              name: "Draw"
</script>./resources/jar/Draw.jar - is the path and the name of the jar

Problem in completing the TASK when using Web Dynpro Java and BPM

Hi,
I am using Web Dynpro Java and BPM.
i see my Web Dynpro View when i run the process.
Just that the task is not completing.
when i click on the Web Dynpro button to signal the completion of the event, nothing happens.
i have appropriately created events in both Component controller and Interface Controller and used the same in creating the Task.
a method in Component controller fires the event and a button click in the view calls this method.
i have successfully completed Donka Dimitrova's "SAP Netweaver Business Process Management-End-to-End Process Implementation Sample " but when i tried my own with slight modifications, it is not working !!!

regards,
-Amol Gupta

Hi Amol,
The way you described the things, I dont see any problems. Just to make sure that you are triggering the right event that you mapped as completion event for the task, try to cross check once again and see if the correct event is getting triggered. Also try to put some messages for debugging to see till where the control goes.

Problem when using WEB.SHOW_DOCUMENT and passing in lexical parameter

Hi,
I got a blank page with error "An error has occured while trying to use this document" when I tried to use web.show_document and passing a lexical parameter to 10g report on 10gAS. The URL in the web.show_document is:
http://<srvname>:<portnum>/reports/rwservlet?server=repserver90&report=myrpt.rdf&destype=Cache&desformat=pdf&userid=<usr>/<pw>@<db>&where_clause=where%20product_type%20in%20('REPORT')
If I change the desformat to htmlcss, it is fine to display the report. But doesn't work with desformat=pdf. The pdf file has been generated in the cache. Why can't it display on the screen.
Also I tried to use double quote the value for where_clause. The pdf report showed up. But it ignored the where clause.
Experts please help.
Ying

I use lexical parameters and they work fine, but I use a parameter list. The code is contained in a form that is called by all forms that wish to run a report. This way you only need the logic for printing in a single form. If you want the form, email me at [email protected]

Very Urgent Unable to Launch Application using Web Start using JDK 1.4.2

Hi all
I am very serious issue i have ejb client swing application that uses
RMI to contact a session bean deployed in JBoss now i want the client app to be installed in the client machine using web start . Also i understand i require security permission to access network resources. so i have signed all the JAR files with same certificate created using self certificate avialiable in JDK by default also in the JNLP file in have included the following tag
<security>
<all-permissions/>
</security>
Now when I launch my application using Web start it gives an error that " Unsigned application is trying to access local resources"
I unable to understand what could be the problem . Please help me with the steps to be followed where in client should be able to RMI call to the server
Thanks in Advance
Naveen

You may have tried this already, but you might have to sign the jars via command line, outside any export process from your IDE.
$ jarsigner {filename}.jar {key from keystore}
I also had problems using webstart and RMI through an RCP

Using Spring beans from EJB MDB

I have a situation where I need to use spring beans from an EJB 3.0 MDB. The project does not have any webapps or anything,
it will be only a MessageBean facade that needs to call spring beans. It is meant to be a service, that can be called by usign a single EJB message.
The problem is I cannot get the spring context to load properly, since the MDBean it self is initialized(constructor called) only when it receives the first message from the broker, thus It's "too late" to initialize the spring context. What I want to do is load the spring context when the EJB is deployed in the Java EE container. So, is there a way I can call a some method, class, anything when the EJB is deployed in the container. Can I do something with a deployment descriptor?
I am using glassfish V2 UR1, EJB 3.0, Spring 2.0.7 The project is deployed as a jar.

Spring's contract first web services are a very nice way to go. It hides the fact that you're using a message-driven component for processing, too.

what is problem you guess.. ?

yes. service provider and consumer both are generated in weblogic.
the only thing i did is to revise the 'weather' web service example to use java
bean ( complex type ).
( the 'weather' web service example was in Document 'Programming WebLogic Web
services' )
thanks for quick response.

Hmmm. Is this all being generated in WebLogic or are you using an external

in 6.1
and you might have to move to 7.0 for more complete web service support.

I have checked WSDL and i found another mystery.
In my WSDL document that is generated in webLogic 6.1,
'weatherResult' element's schema is like below
<complexType name="weatherResult">
<attribute name="temperature" type="float" />
<attribute name="zipcode" type="string" />
</complexType>
as you can see, return element is supposed to be named 'weatherResult'and composed
of attributes
but responsed element is like below
<return xsi:type='bean:weatherResult' xmlns:bean='java:examples.webservices.rpc.weather'>
<temperature xsi:type='xsd:float'>-273.15</temperature>
<zipcode xsi:type='xsd:string'>SomeString</zipcode>
</return>
there are two strange things.
1. there is 'return' element .
2. 'temperature' and 'zipcode' are elements, not attributes.
where did 'return' element come from? and why response element is composedof
elements?
why it doesn't match up to WSDL document?
I think that this problem caused error to instantiate weatherResultBean.
do you know why?
thanks for reading.
Sam Pullara <[email protected]> wrote:
It looks to me like you are returning a temperature and a zipcode but
your
weather result is expecting a zipcode and a temperature so the constructor
is
being called with a (float, String) rather than a (String, float).
At
least
that is my guess. Maybe the two are listed in the other order in the
WSDL?

JAVA WEB SERVER Problem

Hai,
I am using Java Web Server 1.2 . In JSP , when I use
ResultSet.previous(), it is saying that :
java.sql.ResultSet.previous() command not found. I do not know what to do ?
But, In java file, it is working fine without any problem .But, I need to implement in JSP only.
When I use the bean, which consists Rs.previous() also it says Resultset.previous() Command Not found It is very very urgent to me.
Pl help me.
Thanks & Regards

S,
1. Yes, you're rigth. Something is missing here.
2. If it works for Java App and not in JSP,
that would mean JAVA see your jdbc driver and not JSP
but then how come JSP can use Connection ???
3. I think we need some expert to clarify about setup on your machine. Some thing is not set up well so that JAVA app and JSP see at the same time. It look like only JAVA app see the whole.
4. Can you post your article in JDBC forum also in waiting?
