Bytes from jsp to MIDlet (newbie question)

Hi,
is it possible to send bytes from a jsp page to a MIDlet?
actually i want to send an image as bytes to the MIDlet from the jsp.
for this, i don't know how to obtain an image in the jsp.
( i mean withnthe jsp , for the image to be then sent to the MIDlet).
i tried using HttpURLConnection unsuccessfully.
plz help.

thank you Mr.Prabhu.
the client side of the work is over.
i have established a connection to jsp and
BUT NOW I WANT THE JSP TO POST THE IMAGE TO THE MIDLET.
i am able to access the image directly from the MIDlet, but now my target is to send the image in an outputstream from the jsp to the MIDlet so that my MIDlet can receive it as bytes using the inputestreamn object.

Questions/answers from jsp to java bean

Hi
This is what i need to do .
I am showing some questions, say 4 of them , and radio buttons(yes/no) as answers in the JSP.
Now how do i transfer these questions and their answers from jsp to java bean .
I did try hashmap ,but not quite working .
any help?
thanks

Name each radiobutton differently, and then provide 1 property and accessor methods for each of your four answers in the JavaBean, with the same name as specified in the HTML FORM.
So in the HTML:
<input type="radio" name="answerOne" value="true"...>
and then have a property named answerOne with accessor methods in the javaBean...

Launching a Discoverer report from jsp page

Hi
I have a discoverer workbook created using BI Discoverer (for relational). I want to accept some parameters for this workbook from a jsp page, which will also have a "View report" button. This button when pressed should open up the Discoverer workbook and all the parameters from the jsp should be passed to the workbook.
Is it possible? If yes, any details on it?
We do the same thing successfully to launch Oracle Reports from jsps, we simply build the url in the jsp, and from jsp we submit it to a new window, and it opens up the report. Similar functionality we are looking to launch Discoverer reports.
Any help will be appreciated.
Thanks
Shalu

You can open the workbook with URL parameters with Discoverer Viewer much like you would Oracle Reports. Setting anything form the username, password, workbook name, worksheet, and parameters. All the information can be found in the following document:
http://download-east.oracle.com/docs/cd/B14099_11/bi.1012/b13918/urlstart.htm
The specific question your asking is addressed under 13.5.2 Example 2. Let me know if you have any issues

Total Newbie Question ... Sorry :-(

I know it's a windows thing, and I am now converted to Mac but I gotta know this because it's doing my head in. It's a complete stupid green gilled newbie question.
When installing new programs on a Mac can you create shortcuts to the programs on the Dock? I did what I THOUGHT it would be, i.e I made an Alias and stuck it in the dock, but on rebooting my Mac later on, in place of the shortcuts where 3 question marks which when clicked on did absolutely nothing???
Help?

You aren't installing something from a dmg file are you? The dmg is a disk image – kind of a virtual CD. So when you double click the dmg and then get the little disk/hardrive/custom icon on your desktop that is the same as if you had mounted a CD. You then need to drag the application off of that "CD" into your application folder. Then it is truly installed.
You can then "eject" the icon your your desktop. This is what happens when you shutdown and without remounting the image your dock shortcut can't find the original.
Just a thought.

Newbie Question about FM 8 and Acrobat Pro 9

Hello:
I have some dcouments that I've written in FM v8.0p277. I print them to PDF so that I can have a copy to include on a CD and I also print some hard copies.
My newbie question is whether there is a way to create a PDF for hard copy where I mainitain the colors in photos and figures but that the text that is hyperlinked doesn't appear as blue. I want to keep the links live within the soft copy. Is there something I can change within Frame or with Acrobat?
TIA,
Kimberly

Kimberly,
How comes the text is blue in the first place? I guess the cross-reference formats use some character format which makes them blue? There are many options:
Temporarily change the color definition for the color used in the cross-reference format to black.
Temporarily change the character format to not use that color.
Temporarily change the cross-reference definition to not used that character format.
Whichever method you choose, I would create a separate document with the changed format setting and import those format into your book, create the PDF and then import the same format from the official template.

Passing value from JSP to scriptlet

Hi
I am trying to find a way to pass a value from jsp to the scriptlets, i.e.
<c:set var="testValue" value="123" />
<%
System.out.println(testValue);
%>
the above code just demonstrates what I was trying to achieve, by passing the value from the jsp into the scriptlet.
Can someone tell me if there's an easy way to do this?
Thank you.

Note, using scriptlet code on your page is generally something to be avoided. 99% of what you should be doing on a JSP page can be done with EL/JSTL. If you can't do it with EL/JSTL then it probably belongs in a servlet/bean.
I always aim for 100% scriptlet free jsp pages.
Having said that, I can still answer your question: EL attributes are stored in the scope - page, request, session, application
${testValue} is equivalent to pageContext.findAttribute("testValue").
The <c:set> tag example doesn't specify a scope, so therefore you could get it like this:
<c:set var="testValue" value="123" />
<%
String testValue = (String)pageContext.getAttribute("testValue");
System.out.println(testValue);
%>alternatively exploit the feature of the useBean tag that creates a scriptlet variable:
<c:set var="testValue" value="123" />
<jsp:useBean id="testValue" type="java.lang.String"/>
<%
System.out.println(testValue);
%>Note that the EL variable and the Scriptlet variable are initially pointing at the same String.
But changing the string in scriptlet code will change the value it is pointing at, while leaving the EL variable untouched.
If you have a List in scope, and sharing it between EL and scriptlet variables then any changes to the list would be reflected because they both point at the same List object.

How to call custom Login Module from JSP

Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
Mike

You have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it!

Removing ADFBindingFilter from jsp page

I have showReport()method in showReport bean (it is not registered in faces-config.xml as managed-bean) that I am calling from jsp page with JSP call showReport.showReport(). My showReport() method looks like this:
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding("#{data.documentReportsPageDef}");
DCBindingContainer dc = (DCBindingContainer) vb.getValue(fc);
OperationBinding execute =
dc.getOperationBinding("ExecuteWithParams");
execute.execute();
Headless_ documentReportsPageDef code:
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
version="10.1.3.36.73" id="documentReportsPageDef"
Package="...view.pageDefs">
<executables>
<iterator id="DocumentReportsIterator" Binds="DocumentReports"
RangeSize="-1" DataControl="AppModuleDataControl"/>
</executables>
<bindings>
<action id="ExecuteWithParams" IterBinding="DocumentReportsIterator"
InstanceName="AppModuleDataControl.DocumentReports"
DataControl="AppModuleDataControl" RequiresUpdateModel="true"
Action="95">
<NamedData NDName="DocumentType" NDValue="@CDBR"
NDType="java.lang.String"/>
<NamedData NDName="RefNo" NDValue="12635"
NDType="java.lang.String"/>
<NamedData NDName="IsInstant"
NDValue="1"
NDType="java.lang.String"/>
</action>
<table IterBinding="DocumentReportsIterator" id="DocumentReports" >
<AttrNames>
<Item Value="Id"/>
<Item Value=".."/>
</AttrNames>
</table>
</bindings>
</pageDefinition>
It is registered in DataBindings.cpx
Everything works fine until I remove:
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
from web.xml so ADFBindingBindingFilter would not be invoked for my jsp page. I have reason for this
On execute.execute()line I get:
Resolving collection source:DocumentReports for iterator binding:DocumentReportsIterator
DCUtil, returning:oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding, for DocumentReports
Looking for RSI with name :DocumentReports for iterator binding:DocumentReportsIterator
DCBindingContainer.reportException :oracle.jbo.JboException
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
If I restore filter-mapping so adfBindings are used for *.jsp page I get:
Resolving VO:DocumentReports for iterator binding:DocumentReportsIterator
DCUtil, returning:oracle.adfinternal.view.faces.model.binding.FacesCtrlRangeBinding, for DocumentReports
Column count: 13
So everything works fine again.
Question: Can I make this work without ADFBindingsFilter on jsp page? I am invoking everything programmatically and I don’t understand why I need to set this filter on jsp?
With this strange implementation, I am trying to solve problem discussed in article:
oracle.jbo.common.Lock locks the application
If my idea is hopeless, please clarify me this :)

Ok, this is quite clear answer. Thank You.
One more thing:
In oracle.jbo.common.Lock locks the application Steve M, has left the the question open by "I'll ask one of our developers to comment in this thread on ideas for implementing this long-running report.". Maybe You could close this one too?

Domain name settings - Newbie question

Sorry for a newbie question!
I am already pointing a domain name to web hosting for email account. Now, I need an application server to run ERP software and Oracle, and installing Solaris and Oracle need a domain name.
If I point my domain name to the server, how do I receive emails from web hosting???
Install an email server to the application server instead? What can I do if I want the same domain name? Any option?

Setting up a mailserver and making sure it doesn't suddenly turn into a spambox is not something you do with the use of a few commands. I suggest to dive into the Solaris admin guide on docs.sun.com and read up on e-mail and network services.
If that is asking too much of your time you'll be better off getting your ISP to handle all this for you.

Your questions are completely off-topic for the forum.
These SunOS forums are for questions on <i>"how do I install my OS"</i>
You particular question is in the <i>"how can I install Solaris while using the CD drive"</i> forum.
So, if you had a question on how to edit the /etc/inet/hosts file to establish a FQDN on the computer, then it might be appropriate for the forum.
Unfortunately, I don't have a clue on where to redirect you, except perhaps to the Sun Java Enterprise System suite of applications?

Newbie Question: How much computer do I need?

Newbie Question:
I would like to use MainStage 3 in a live performance environment to play bars, parties, etc. I'm not looping, using it to playback recordings, processing outboard equipment or vocal processing. I want to stop carrying Rolands, Nords, Korgs, etc and get to a controller and a rack with a Mac Mini in it.
I tested a download of Mainstage 3 on my home Mac Mini (late 2012, 3.5 Ghz i5, 4GB RAM, 500GB drive) and it seemed to run fairly well. $30 well invested so I trekked forward... I purchased a Mac Mini (late 2009, 2.52GHz Core 2 Duo, 6GB RAM, 128GB SSD) for $200. I started to do more elaborate keyboard setups to see how the CPU would hold up. It typically runs from 30% to 50% of capacity (CPU and Memory) It actually boots and runs better than the i5. I hear the occasion gitch, but it actually seems to be getting better in time (or I'm rock and roll deaf.
I got a rack, an Airport Express, a Radial USB interface and a Nektar Panorama P6. It's starting to get expensive, but I'm emboldened by the actual quality for the sound and the flexibility of arranging for live performance. What used to take me two and three keyboards to play, I can now fit on one performance patch.
OK, now the question... am I at the limits of this little Core 2 Duo? Should I upgrade the i5 with more RAM and a bigger SSD and use that? Should I get a new(er) i7 and bite the $1,500 bullet for the additional RAM and SSD?
I see that most of you are running pretty nice Macbook Pros with i7 and lots of everything. My needs are modest; am I OK?
BTW, I want to run a Mac Mini in a box because I don't want to carry a laptop out in the open. If I was doing bigger shows I wouldn't care but I play some rowdy bars and constantly have folks hanging off me while I'm playing. It's fun, but hard on gear. If you can't drop it or dip it in beer, it won't last long where I work.
Matt Donnelly

Rule of thumb: newer and faster is better. But, depending the complexity of your needs you may be OK with an older Mac. Some glitches that happen in a live performance are due to loss of communication with USB or Firewire inputs, so make sure they're secure. I recently upgraded from a 2010 Mac Mini 2.6 dual core with 16 GB RAM, which was used live for nearly four years, to the latest Mac Mini 3.0 i7 with 16 GB RAM and a 500 GB SSD. I was getting an occasional stuck note with the older one. The new one is rock solid. Some of my patches may have up to a dozen channel strips mapped to three keyboards. The Mini is mounted in a rack next to a MOTU Ultralite Hybrid. It is a good idea to map a panic button on your keyboard to controller # 123(all notes off). Also, you might want to invest in a battery backup power supply(APC, Cyberpower, etc.-$40-$60) to protect your Mac against power loss, which can damage you hard drive.

Multiple version of JRE in company..How to manage? (newbie question)

Greetings..this is a newbie question
We have 48 versions of JRE running in on XP IE6 in our company.
Some version beat up other JAVA applications.
It's a mess.
How can anyone manage this many versions?
Can we consolidate down to a few versions?
I saw some posts on changing the JRE dynamically or perhaps using a wrapper with a product from "sourceforge".
Are these viable?
Thanks in advance

It's a mess.can you elaborate on how some versions "beat up" other apps?
How can anyone manage this many versions?you don't, each computer should periodically upgrade (IMO) but you shouldn't care. if you do, tell your users to load the latest version
Can we consolidate down to a few versions?sure

Moving Scriptlet Code to backing bean when converting from JSP - Facelets

Hello!
We are converting our application from jsf1.2 to 2.0 and all jsps are being converted to XHTML. Some are trivial while others had very complex scriptlets.
I would like to know what are some of the recommended ways of moving Scriptlet Code to backing bean when converting from JSP -> Facelets.
I have thought about listeners, actionListeners, putting code getXXXX() of the backing bean and then calling #{bean.XXXX} but not sure whats the best way.
I do appreciate the response!
Eg of a jsp page:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="/WEB-INF/xxx-jsf.tld" prefix="l" %>
<%@ taglib uri="/WEB-INF/yyy-pp.tld" prefix="p" %>
<%@ page import="com.ttyy.search.beans.jsf.AdvancedSearchFormManagedBean" %>
<%@ page import="com.kkee.util.*"%>
<%
    AdvancedSearchFormManagedBean advancedSearchFormManagedBean = (AdvancedSearchFormManagedBean) request.getSession().getAttribute("AdvancedSearchFormManagedBean");
    if (advancedSearchFormManagedBean == null) {
       advancedSearchFormManagedBean = new AdvancedSearchFormManagedBean();
       request.getSession().setAttribute("AdvancedSearchFormManagedBean", advancedSearchFormManagedBean);
    advancedSearchFormManagedBean.initializeForAdvancedSearchOptions();
    advancedSearchFormManagedBean.setQuickSearch();
     request.setAttribute("portletHeader", "Hello " + advancedSearchFormManagedBean.getPerson().getFirstname() + ", check out the latest programs in your practice areas and jurisdictions");
%>
<h:form id="MYCenterForm">
     <p:portletRenderer portletSetName="test of portlet"
          portletContainer="#{PortletContainerManagedBean}"
          id="MYCenter"
          portletScope = "TEST_SCOPE"
          suppressIfNoData="true"
          portletSkinName="SOME_SKIN">
          <f:facet name="persistenceToolkit">
               <h:commandLink id="persistenceToolkitLink"
                    actionListener="#{PortletContainerManagedBean.persistPortletSetStateListener}">
                    <h:outputText value="Save State Of Portlet Set" id="persistenceToolkitLinkText"/>
               </h:commandLink>
          </f:facet>
     </p:pagePortletSetRenderer>
</h:form>
<%
     String flag = PropertyItems.getInstance().getPropertyItem("response.time.flag");
     if("1".equals(flag)){
          ResponseTime rt = (ResponseTime) session.getAttribute("responseTime");
        if(rt!=null){
            rt.setDesc("my cle loaded");
            long now = System.currentTimeMillis();
            long start = rt.getStart() + rt.getTotal();
            rt.setInterval(now-start);
            rt.setTotal(rt.getTotal()+rt.getInterval());
            LogUtil.log(rt.toString(), LogUtil.DEBUG_LEVEL);
            session.setAttribute("responseTime", rt);
%>

That helps.
This could be another topic question but itst kind of related to what i am doing right now. while converting JSP to facelet (in jsf2) I came across another issue.
<h:commandLink id="Save" rendered="#{RegistrationBean.isNOTInOrigionalRegistrationMode}" action="#{RegistrationBean.updateProfile2Submit}" styleClass="#{portalSkinManagedBean.contentPortletSkin.strongTextStyle}">
          <l:htmlSkinnedImage id="SaveImage" style="border:0;" url="save.gif" alt="Save Information"/>
</h:commandLink>When I click on the generated link, I get this. And this is happening for all the h:commandLink in the application.

Calling method from jsp file

Hi
is it possible to call any method with in the class except handle method from jsp file?

You can call , but it would not be a good design approach.A droplet can do the same task for you.
otherwise :
eg :
<%@ page import="com.mypackage.MyClass"%>
for Static access :
<%
String test= MyClass.myMethod();
%>
for normal classes :
<%
MyClass object = new MyClass();
String test= object .myMethod();
%>

<br><br>
if (object1 instanceof A){
if (object1 instanceof A1)      {A1   object2 = (A1) e;}
          if (object1 instanceof A2)      {A2   object2 = (A2) e;}
          if (object1 instanceof A3)      {A3   object2 = (A3) e;}
          if (object1 instanceof A4)      {A4   object2 = (A4) e;}
          if (object1 instanceof A5)      {A5   object2 = (A5) e;}
object2.callMethod();
<br><br>
Is there any way to do this type of casting just in one line? I mean, I just want to cast object1 to the class it is instanceof. If it is instance of A1, I want to be casted to A1, if it is A2 to A2, etc...
<br><br>
Thanks you in advance.

In fact I know what object1 is on execution time,Which doesn't help your compiler at all, when it's task to link and verify method calls.
because the code posted at the top is working well, i just want to avoid repeating that if's for all the new classes Ax I will create. Big "code smell" here.
In other words if i had from A1 to A200 i dont want to have 200 if's to cast it to the class it is and then execute it's method.You could call the method "doMagic()" and make it abstract in A. Then you can implement it in all Ax classes and would never have to worry about casting in the first place, because A.doMagic() would automagically do the right thing. Polymorphism.
