CreateViewObjectFromQueryStmt in jsp
Can anyone tell mi if it's possible to use a viewobject you created using createViewObjectFromQueryStmt as the datasource of a jsp page, showing the data as a read only dynamic Table. If it's possible could anyone please provide me with an example how to do this.
So far I'm able to create the viewobject in the application module, but I realy have no idea how to add the viewobject to the bindingcontainer.
Thanks
Is the view object in your application such that the select list is not known until runtime?
Or is it just the where clause or bind variable values that aren't known until runtime?
I find many customers use the createViewObjectFromQueryStmt() API because it's easy without realizing:
(a) They could have created the view object at
design time using just the desired SQL statement
without being related to any Entity Object, and
(b) They incur a runtime overhead of describing
the dynamically-supplied query so ADF can
determine the attribute names and datatypes.
Does your situation require a truly-dynamically-supplied SQL statement?
If so, I have an example I can send you, but I'd recommend that unless you truly need this level of dynamicity, that you create an expert-mode SQL statement-based View Object at design time. It will perform better and is easier to use.

I have a JSP page where I want to display the results from a query with a parameter supplied by a form.
The problem is, my query does not have a where clause but instead is a hierarchical query e.g.
http://www.dbazine.com/mishra3.shtml
SELECT LEVEL, EMP_NAME , EMP_ID, MGR_ID
FROM EMPLOYEE
START WITH MGR_ID IS :1
CONNECT BY PRIOR EMP_ID = MGR_ID;
Where :1 is where I want to put in a parameter.
Can I do this using an ADF ViewObject and JSP page?
I am open to design suggestions here.
I have tried two naive ways of doing this which did not work.
1. Just try to set the parameters before opening the page using a DataActionMethod that opens the page on success
ViewObject vo = findViewObject("TrayTrackFwdHistory1");
vo.setWhereClauseParam(0, my_parameter);
vo.executeQuery();
In this case, somehow the page errors out before the set method is invoked with a ":1 is not set as an input or output parameter"
2. Simply drop and recreate the view object with the query parameter value inside it. e.g.
ViewObject vo = findViewObject("TrayTrackRevHistory1");
vo.remove();
vo = createViewObjectFromQueryStmt("TrayTrackRevHistory1", sqlStr);
vo.executeQuery();
In this case I get the error
Operation getCurrentRowSlot cannot be performed because the working set object is not bound. So somehow I have to reset the iterator binding for the JSP page I generated versus the above view?
Any help much appreciated.So, I figured out the solution for this.
The answer here was to set the parameter value in the prepareModel event before the page is loaded. It turns out that setWhereClauseParam seems to set a parameter even if it is not part of a where clause so e.g.
protected void prepareModel(DataActionContext ctx) throws Exception {
String manager= ctx.getHttpServletRequest().getParameter("manager");
DCDataControl dc = ctx.getBindingContext().findDataControl("AppModuleDataControl");
AppModule am = (AppModule)dc.getDataProvider();
ViewObject vo = am.findViewObject("EmployeeManagers");
vo.setWhereClauseParam(0, manager);
vo.executeQuery();
super.prepareModel(ctx);

ArnoldAccording to the release notes, for the JRCHelperSample to compile, you must set the target runtime for the project.
To do this, either create a project from scratch that uses the Tomcat 5.5 target runtime, or go to the properties menu and ensure that the target runtime is set to the application server you will be using. -
.How can I add data from one list to other in Jsp Page
Hi..I have three multiple selection ListBox..I want to add the selected item from 2 list boxes to 3rd list box how can i do that..do i need to write javascript? If possible then suggest me some link where i can get help?
Thanks
Regards
ChintanYep, Javascript.
Unless you want to post the data to the server and then rewrite the page (ie. jsp/servlets) then you are going to need to use a client side script to modify the page.
Javascript. You need to get the onClick() event of one list box and get the item that was clicked. then you can rewrite the 3rd list box.
If possible, try doing a search on google. Or do you want someone to hold your hand. -

Thanks in advance.HTTP is a request/response protocol. You can't do what you're suggesting without "pushing" what you type to all the other users. That's not the way HTTP works. Maybe an applet and servlet.

How to print new line in jsp page
hi
how to print new line in jsp page
thanks\n - new line character is in java specific not HTML
specific.Well, if the correct line separator sequence (by far not always \n) would be used, it does add a new line to the HTML output. Too bad that you don't want to see HTML but formatted text. The BR tag is a formatting element for the displayed text, not a line break in HTML. ;) -
How to Get Portlet Namespace in a JSP attribute
Hi All,
The id of any component in a JSF application (with JSR168 portlets) takes the form
'view'+'<portlet:namespace/>'+':'+'formname:componentidname';
I need this id to be used for certain validations.
Currently I am using it as below :-
<h:intputText required="#{ ! empty param['viewns_7_CGAH47L000NAF0I04I42ND10P7_:form:login']}"/>
Presently I have hardcoded the portlet namespace 'ns_7_CGAH47L000NAF0I04I42ND10P7_' by looking into the html source of the rendered page.
Is there any way by which i can automatically get this portlet namespace within the param tag in the jsp.
I know for a fact that within javascript tags, it can be used as <portlet:namespace/> as shown below :-
<script type="text/javascript">
function doSomething()
buttonId= 'view' + '<portlet:namespace/>'+':'+'formName:buttonId';
document.getElementById(buttonId).disabled = true;
</script>
Kindly treat this on high priority.
Thanks and Regards,
Darshan ShroffPerhaps so.
I need to use it within param as below
<h:inputText value="#{bean.userid}"
required="#{!empty param['viewns_7_CGAH47L00GLRE0I0BCOUKS00I5_:form:login']}" />
Here 'viewns_7_CGAH47L00GLRE0I0BCOUKS00I5_:form:login' is actually
'view' + '<portlet:namespace/>'+':'+'formName:buttonId';
I am just trying to check the presence of the client ID in the request paramameter map inorder to attain action dependent requiredness.
Kindly tell me how i could access it within param.
Thanks & Regards,

Remote system JSP project not working in eclipse
Hi
I am developing a JSP project. My files are on a remote server and I want to configure it in Eclipse 3.3 with Lomboz. The problem is After adding the project it gives a warning that xml files can't be validated.The exact warning is
The file cannot be validated as the XML Schema "\192.168.1.10\gunjan_share\workspace\Project1\WebContent\WEB-INF\web.xml (The system cannot find the path specified)" that is specified as describing the syntax of the file cannot be located.
Due to this error JSP pages are not getting compiled.
Plz help me
ThanksExtracted from Note 1067696.1:
You need to either adapt your code to remove the scriptlets in your JSP page,
or you can use the following Java option to disable OJSP:
-Dadfvdt.disableOjspDeployment=true
You can add this option -Dadfvdt.disableOjspDeployment=true in your file "ide.conf" in the directory "<Middleware_Home>\jdeveloper\ide\bin"
For your Production environment, you can have your Managed WLS ignoring the OJSP mode by adding the Java Option -Dadfvdt.disableOjspDeployment=true
* in the "startManagedWebLogic" (if you want to limit it to a specific Managed Server)
* or "setDomainEnv" (for all managed servers in a domain). -

Thanks,
Ritendra.I think too, that is a time machine problem.
I have 4 volume partions (3 hard disk) at this mac. I use only the time machine as backup system. Only one. Before I install Snow Leopard I use the latest MacOS X 10.5.8. Always the newest version of MacOS.
Perhaps I describe it: Under 10.5.8 I use the time machine backup volume at an external firewire drive, always the same. I switch off this firewire drive often. In this case (the drive isn`t connect) the icon of this partition"Pro10.4" was changed to the time machine volume icon, but the time machine does nothing at this partition.
After the installation of 10.6 I cannot access to this "Pro10.4" volume. I get the same error message if I want to open the external drive volume of my time machine backup. There is no problems with my other two partition. Of course my old V10.5.8 is at one of this partition. If I start my mac from a other partition (time machine is off), I have no problem with all partitions.
I change the name of "Pro10.4", but nothing is changing. The time machine protect the backup volume under V10.6. Unfortunately it choose an other partition, if it don`t find my external drive. How can I reset this state of my "Pro10.4"?
Thanks

Hi, everyone.
I'm getting an error trying precompile JSP code using a variable tag in my tag library to define a new scripting variable : Element "tag" does not allow "variable" here.
I also get the same error after deployng the JSP code on Sun One Application server 7.
Any idea?
Thanks a lot for any help.Here is the tag lib file that can't be parsed.

Error in executing a process for compilation for jsp
We have an iView which has jsp pages in it. We deployed the par & try toaccess the iview & we get an exception. The issue is that the iview has a jsp page. At the run time, this jsp is converted into a .java file
without problem. But EP engine is having issues compiling this java fileinto .class file.
On the other hand this same iview works just fine on our windows installation. Only Solaris EP install is having problems. The version onwindows as well as on Solaris is EP6 SP9.
Here is the exact version on the solaris EP:
sap.com/SAP-JEECOR 6.40 SP9 (1000.6.40.9.0.20041119045253) 20041122132733
sap.com/SAP-JEE 6.40 SP9 (1000.6.40.9.0.20041119045409) 20041122132741
When I copy the .class file from windows to unix machine, the iView works fine. Here is the exception I am getting:
>>> JSPCompiler >>> error

I am having the same issue with another iview which has jsp page in it.
The web dynpro iview works fine.Hi, seems like there's some typo in your jsp. Check the .java file listed with a java editor (like eclipse or devstudio.). Maybe you'll find the typo this way faster.
Most often, a multiline page import hampers jsp compilation,
e.g.
<%@page import="java.util.List,
java.util.Map"%>
needs to be
<%@page import="java.util.List,java.util.Map"%>

Using a variable as a value in jsp:param
I was wondering, I have a String variable, vid_1, and want to use a jsp:include and pass that in as one of the parameters. How can I do this? I have to do some testing to make sure vid_1 is valid and set a default if not. It contains a number referring to which video needs to be displayed.
Is there anyway I can get this value to be used in jsp:param value?

Well,First thing you haven't pharsed your question properly.
Anyways as per my understading.
The first thing is make use of in this case as your defined requirement states you need to make use of variables of both the JSP's which need compile time include not at the runtime.use of
<%@ include file="url" %>would be more appropriate as you want to use the variable of parent jsp to the child one.
Anyways if you are thinking to apply a solution using <jsp:include/>
<jsp:include page="url">
<jsp:param name="paramName" value="<%=stringVariable>"/>
</jsp:include>and extract the paramName's corresponding value as a request parameter in other JSP.
Hope that might answer your question :)
REGARDS,
RaHuLRaHul,
Thanks for the reply. The second example you gave is what I was trying to do. I thought I did exactly what you have there and it was not working. I will check it over again and post back on here when I have a chance.
For now I was trying to use c:set to save the variable in the request and then using the EL expression ${requestScope.variable} to put it in the <jsp:param> element. I had some things working and others not when I quit. Hopefully tomorrow I can give you a full report and we can get this worked out.
Maybe my problem is something else? Look at this post of mine:
http://forum.java.sun.com/thread.jspa?threadID=5236252&tstart=10
Thanks so much for the help.
