Displaying userform on jsp page

Hi.
I'm using idm 5.5
I created new form (with BPE) that displays some messages defined in rule.
I would like to display this form on jsp page. How can I do it?
Or is there any other way how to display strings defined in rule on jsp page in IdM?
Thanks

What do you mean "print data on a JSP?" If you simply mean display dynamic content, you should def read up both on sun's resources and other googled resources for JSP walkthroughs...

Junk characters like" � � "displayed in the jsp page please help.

Hi,
I am getting junk characters like � � displayed in the jsp page.
In the JSP page i used javascript "& nbsp" for appending spaces to a string "CCR" to get "CCR " .
Now the Resultant string "CCR " has three spaces appended to its right.
This String is set in session in that JSP page.
In the next JSP page i am getting that string from session.
After getting the string the "substring" function is performed to get only the first 5 charcters of the string. Now the result is displayed as " CCR� � " with has last 2 characters as junk values � � insteed of displaying as "CCR ". Please help me in solving this issue.
Please note that initially the sting "CCR" is got from the Oracle database in Solaris Machine.
Regards,
Vijay

have you tried:
strenuously inspecting the string that is coming from the db? do an actual loop over the string, character by character, dumping to System.out to make sure the characters are EXACT coming out of the db.
note you have to append " " not just "& nbsp"
post the code that is doing the output. the relevant bean code, the jsp, everything relevant - WITH COMMENTS discussing where things are happening.
Also, is it "weird characters" in the browser only? have you done a view source on the actual html source that the browser is rendering (right click in IE and click view source). browsers can act odd if you don't feed then exactly what they want, and it looks like you're feeding it escaped characters that it is rendering as something else.

Display image on jsp page

I have to display image on jsp page with some text output. This image is already saved at a location parallel to web-inf and is generated dynamically using a servlet. I have used img tag html to display the image. Other outputs are taking their values from database.
First problem is that image will be taking time to display in comparision of other outouts from database. I have to refresh the page to get imageon my page.
Second is that if I save image in a folder parallel to web-inf in my project then it will not be displaying the image.
Can I use any jsp functionality to display image with other outputs from database. I have used "*include*". but it shows only that image and other outputs.

Best way is to use a servlet for this.
<img src="path/to/imageservlet?id=someidentifier">

<img src="path/to/imageservlet/someidentifier">In the servlet's doGet() just write code which gets an InputStream of the image (either directly generated, or just read from the local disk file system, if necessary with help of ServletContext#getRealPath(), or even from the DB by ResultSet#getBinaryStream()) and writes it to the OutputStream of the response. That's basically all. Don't forget to buffer the streams properly to speedup performance and to save memory.
You can find here a basic example: [http://balusc.blogspot.com/2007/04/imageservlet.html].

               out.println(imgLen.length());Your JSP was supposed to write an image to the output and you wrote some irrelevant strings to the output before? This will corrupt the image. It's like opening the image in a text editor and adding some characters before to it.
               byte [] rb = new byte[len];Memory hogging. Don't do that.
          out.println(ee);You should be throwing exceptions and at least printing its trace, not sending its toString() to the output.

Problem in displaying image on jsp page

I want to display an image on jsp page.I copied the image the image in WebContent folder.
I am able to see the image on the design pane when using the following code:-
<img src="/image.gif" height="50" width="50"> but when i run it in the browser nothing gets diplsyed.
also when i use the image container and select the source option that image is not displayed in the WebContents file..plz help.

Hi,
Seems that the Problem is there with the way how you specifuied the Image relative Path:
You have specified the below: The opath of image starts with (/) forward slash:
*<img src="/image.gif" height="50" width="50">*
It means to access this Image WebLogic Container will form a Path like this:
http://localhost:7001/image.gif
BUT may be the image is available inside your Context root: So Change the <Img> tag like following in your JSP:
*<img src="image.gif" height="50" width="50">*
(*NOTE:* Never Start your src path with a Preceesing /)
Now WLE will consider the path like below ..if your Applications Context root is "TestApp"
http://localhost:7001/TestApp/image.gif
I am Assuming that Inside the TestApp Application "image.gif" And "your.jsp" jSP pages are Co-Located (Means available in the Same Directory).

Special characters are not displaying in ADF jsp page

Hi All,
By using ADF view controller,I am getting the data from database table but when I display the data in jsp page after special character < what ever the data is there it is not displaced.Provide any suggestions.
Thanks in Advance
Mani

Hi Mani,
< is a special HTML character and obviously it may not me displayed correctly.
Here is a reference of all HTML special characters: http://www.w3schools.com/tags/ref_entities.asp
In your case you can replace < with its special symbol representation - *&#60; or &lt;*
I also advice you to do so for all special HTML characters.
You can use this Java library for that purpose : http://commons.apache.org/lang/api/org/apache/commons/lang3/StringEscapeUtils.html

can I use UTF-8 to display my jsp page, which have Chinese Character in there?Thank you!

Hi Niklas
thank you for the suggestion. somebody told me UTF-8 suppose work, only if you typing your Chiness character in UTF-8 formate, i don't know that is true or not, but that realy a challenge for me, I using jdbc , some time ago, and then stop, and on that period,if I got free time, I did try to learn some tutorials on struct, hibernate, like http://javaboutique.internet.com/tutorials/Struts/; http://courses.coreservlets.com/Course-Materials/struts.html
recently I need to deal with some online form , first I want to use struct, but I keep got forwad problem, I forget the detail error message, and found not place to ask questions, so , I pick jdbc again, so ,if you have some useful link in struct or a nice community for people to learn struct, I am look forward to
know that,
by the way I set *<meta http-equiv="Content-Type" content="text/html; charset=big5" /> in my jsp*
String dbURL="jdbc:mysql://localhost/survey?useBig5=true&characterEncoding=Big5"; in jdbc
keep UTF-8 setting in mysql, it looks solute the problem that I had, hope that can enhabce our knowledge in that
thank you for the help and wish good luck for future.

Displaying content in JSP page, want BR but not other Html tags

I have a page and am reading files and displaying the contents of the files onto the page in a <div> Oneissue is that in the file the end of line are \n or \r\n whichever operation system. I replaced those with <BR> no problem. Now my issue is that I display that in the JSP page:
<c:out value="${filecontents}" escapeXml="false" />I use escapeXml so that <BR> will add the line breaks. Now my issue is that the file might contains other HTML tags that I want to display simply as text - I don't want the browser to render the other HTML tags.
Is there a way to do that? Would I have to replace HTML tags with something special?

Hmm... your file contains HTML tags, but you don't want the browser to interpret them as HTML tags, right? So the way to do that is to use escapeXml="true" in your c:out element.
But then that also escapes the <BR> tags that you carefully put in there. And you don't want that. You want the browser to interpret those as HTML tags.
I guess you can't have it both ways. Can you do something like outputting one line of the file at a time with <c:out ... escapeXml="true"> followed by <br>?

ADF BC:Displaying Image On JSP page

Hai All
I'm using ADF BC and JDev 10.1.3.
I want to show an image on my jsp page from database.
For this I have written an servlet with the following code
response.setContentType("image/gif");
OutputStream os = response.getOutputStream();
String amDef = "package.AppModuleName";
String config = "Configuration Name";
ApplicationModule am = Configuration.createRootApplicationModule(amDef, config);
ViewObjectImpl vo =
(ViewObjectImpl)am.findViewObject("ViewObject"); // get view object (the same as used in the table)
System.out.println("vo:" + vo);
vo.executeQuery();
Row row = vo.first();
BlobDomain image = (BlobDomain)row.getAttribute("field");
//System.out.println("image:" + image);
InputStream is = image.getInputStream();
// copy blob to output
byte[] buffer = new byte[10 * 1024];
int nread;
while ((nread = is.read(buffer)) != -1)
os.write(buffer, 0, nread);
os.close();
Configuration.releaseRootApplicationModule(am, false);
This servlet working perfectly.The image is displayed on the page while running
the servlet alone.
My problem is the image is not got displyed on the jsp page
I tried following code to call the servlet
<af:objectImage source="ImageServlet"/>
<img src="ImageServlet" width="140px" height="50px" align="right">
Where ImageServlet is the url-pattern in the web.xml for the servlet
Both method are not working
Any body please help me.......
what I'm missing..............
Is there any other way to display an image on JSP page using backing bean
method.
Thanks

You also might want to check JDK versions and J2EE versions being used. These might yield different results.

Struts can't display the input jsp page

Hello,
I'm using Struts 1.3.8 to construct a simple user registration system, in which the user could input his info (such as uuname and gpin, both are strings) in a jsp page, and after the submit, the system should go to a success page. However, somehow, when I access the url, it goes directly to the success page, but not stay at the input page.
Here is my {color:#ff0000}struts-xml.config{color}
bq. <?xml version="1.0" encoding="UTF-8"?> \\ <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd"> \\ <struts-config> \\ <form-beans> \\ <form-bean name="{color:#ff0000}anotherUserForm{color}" type="com.visualbuilder.struts.beans.AnotherUser" /> \\ </form-beans> \\  \\ <global-exceptions></global-exceptions> \\  \\ <global-forwards> \\ <forward name="success" path="success.jsp"/> </global-forwards> \\  \\ <action-mappings> \\ <action path="/{color:#ff0000}addanotheruser{color}" type="com.visualbuilder.struts.action.AddAnotherUserAction" name="{color:#ff0000}anotherUserForm{color}" attribute="user" input="{color:#ff0000}/addanotheruser.jsp{color}" cancellable="true"> \\ </action> \\ </action-mappings> \\  \\ <message-resources \\ parameter="registration.resources.ApplicationResources" /> \\ </struts-config>

Everytime I access http://localhost:9080/addanotheruser.do, it jumps to the success.jsp, but not stay at addanotheruser.jsp to wait for the user input, and in the server's console, I could see the output "UUName: null GPIN: null"
I've been stuck at this simple program for three days, could anybody help to find the errors? Thanks a lot.

sorry, the post looks ugly. Does anybody know how to make the indent not disappear?

Display content in Jsp page

Hi All,
When I am trying to display large the data in jsp I have problem...
It will display entire content in one page but I want some data and Click the next hipar link than it will display the next data...
Like yahoo mail box....
Please give me the idea on this issue

you can have a hidden field which stores information about the current record number. so that you can start from the record pointed by the value in the hidden and proceed till delta records and finally increment the value of the hidden field by delta.
for instance, if you have 20 records, and your hidden field value at the beigning is 0.
when the page loads you can read this hidden field value and display 5 records starting from the hidden field value. Finally you can increment the hidden field value by 5. Your link must post your form to this page.

Displaying Image in JSP page

Hi there.. I have a problem with displaying an image from table with blob data type.
Here's what have I done:
I have this page to display an image from requestScope.test (I've set this value in data action).
But the problem is, the image is only displayed once. Seems that after it read the eof of stream, It'll not move the pointer to the beginning. The image will show up again if view object retrieve new data from the database.
Here's my code:
------------------------------------------------------begin of code----------------------------------------------------
<%@ page import="java.io.InputStream,oracle.jbo.client.Configuration,oracle.jbo.ApplicationModule"%>
<%
response.setContentType("image/jpeg");
response.addHeader("Content-Disposition","filename=img.jpg");
InputStream sImage = ((oracle.jbo.domain.BlobDomain)request.getAttribute("test")).getInputStream();
byte[] bytearray = new byte[4096];
int size = 0;
while((size=sImage.read(bytearray))!= -1 ){
response.getOutputStream().write(bytearray,0,size);
sImage.close();
%>
------------------------------------------------------end of code----------------------------------------------------
Any suggestion?
Thx,
Andre

Sorry, I've just read the java doc for oracle.jbo.domain.BlobDomain and find method toByteArray(), and this method can solve my problem. Here's the new code:
----------------------------------------begin of code-----------------------------------------------
<%
response.setContentType("image/jpeg");
response.addHeader("Content-Disposition","filename=img.jpg");
byte[] bytearray = ((oracle.jbo.domain.BlobDomain)request.getAttribute("test")).toByteArray();
response.getOutputStream().write(bytearray, 0, bytearray.length);
%>
----------------------------------------begin of code-----------------------------------------------
But I still intereset with the first solution, why it always find eof after it displayed. I've already closed the stream.
Thx,
Andre
