How do you display images relative to a Portlet JSP page?

For Welblogic Portal 7.0, I want to display a simple image (.gif) on a JSP page.
The problem is that I need to use a 'hard coded' url to the image such as the following:
<img src="portlets/test/images/test.gif" border="0" alt="Test 1">
- OR -
<img src="<webflow:createResourceURL resource="/portlets/test/images/test.gif" />"
border="0" alt="Test 2">
This makes the portlet less portable.
My goal is to display an image relative to the current JSP Portlet page (in the test
directory).
Does anyone know how to accomplish this?
In WL Portal 4.0 I used:
<img src="<%=fixupRelativeURL(pathFromRequest(request) + "images/test.gif", request)%>"
width=24 height=22 border=0 alt="test">
This does not work anymore as fixupRelativeURL does not seem to exist in the 7.0
API.
Your help would be greatly appreciated!
Thanks,
Matt

Exactly what I was looking for!
Thank you Subbu.

Matt,
There is an indirect way to achieve this.
(a) In your portlet JSP, get the PortletState. There is an example in
/framework/portlet.jsp.
(b) Get the content URL for this portlet by calling
portletState.getUrl(Portlet.URL_CONTENT).
Depending on where your image is (with respect to the content URL), you
can construct a new URL to the image. For example if your content is at
at /portlets/myportlet/foo.jsp and your image is in at
/portlets/myportlet/images/myimage.gif, you can reconctruct the latter
from the first one.
Once you do this, prepend the constructed URL with the web app context
root (request.getContextPath()).
Hope this helps.

Creating a File object in a JSP page

Hi,
I am trying to create a File object in my JSP page by passing it a relative path. The jsp page is in 'website/testfolder/index.jsp' and the File is in 'website/photos/1.jpg'. In my jsp page i do the following:
<% File f = new File("../photos/1.jpg");
boolean test = f.isFile(); %>
The value returned is false. I am trying to figure out why it can't locate the file.
Thanks

You have to use absolute paths. You can get the absolute path for the given relative path by ServletContext#getRealPath().

Can't use relative paths in jsp pages or javabeans

Hi everyone,
Can someone please help me with this little problem.
When I want to use in a JSP page the object 'FileReadInput' to read in a file, it can't find when I only give the filename. The target file and source file are in the same directory so I would expect if I only give the filename, it will automatically search in the current directory. But when I give the complete absolute path, everything works fine. Is it possible to use relative paths in a jsp or javabean file?
By the way, I am working with JDeveloper from Oracle. (maybe that has something to do with my problem)
Can someone help me???
Thx

My dear friend,
It will not work at all. coz, for any jsp file, ur application server will create a .java file and then .class file in a directory other than the directory where ur .jsp file present. that's why, ur file to be read can't be found. that's why use the following.
String path=getServletConfig().getServletContext().getRealPath("/")+File.seperator+"yourfilename";

Absolute and relative addressing for stylesheets: issue with IE6 and pages not in the root

The following conditional comment gives me a problem when I arrange my site into folders (instead of all pages in one directory, or all in the root). The directories are built according to the site hierarchy.


</style>
What do you suggest I do to get the pages not in the root to read the dropdown_ie.css file when using IE6?
And I have a feeling that the way I import the styles may not be right, but I am not sure.
Any help will be greatly appreciated.
Erik

I solved this one by changing the relative addressing of my stylesheet location in absolute addressing. And I had to do this not only for the stylesheet, but for all addressing in the html related to this drop down menu:
href="http://mysafety.be/styles/dropdown_ie.css"
Changing the location of my files into subdirectories (and removing the spaces in the file names) also means that all my google indexing got screwed up; I submitted to google the whole list of addresses for removal from their cache. It will be another 4 weeks before everything is indexed correctly again, but I guess I better do this now before the site becomes fully operational.

How to address form controls in jsp page

i cant find anything either on the internet. can somebody help me plz?

Hi Kim,
You can use the following JavaScript command:

You can use this on submit of the form or in a click event at the field.

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

How to include a .class file in a jsp page

hi everyone,
i know the syntax as:
<%@ include file = "filename.class" %>
then at run time the server could not find the class file

<%@ page import = "FileName.class" %>
then also the same problem persists
& if i use
<jsp:include page = "Relative address"/>
the problem still remains as it is...
please help me out...i am working on developing an EJB application in which client interacts with server's Stateful session bean through a jsp page...it is necessary for me to include the home interface class file in my jsp page.
P.S. do not suggest me to include the class file in a package & then use
<%@ page import = "packageName.ClassFileName" %>

"package University does not exist".How can i overcome this problem. The package University, which you are trying to import, must be in the classpath. If you removed it then you will have to add it back.
i have tried my best..but tell me if there's any possible way of including a class file in the jsp page without involving a package.No, there isn't.
If not,then pls help me to generate the class file of my home interface within a package called test.Read the New To Java Tutorial and understand how packages work.

Single signon between JSP page and Net.Data page

I am trying to setup a single signon between a JSP page hosted on a tomcat server, and a Net.Data page hosted on an IBM HTTP server. Both of these servers are running on an AS400. The JSP page (www.jsppage.com/menu) contains a link to the Net.Data page (www.netData.com/page2). In order to access www.jsppage.com/menu the user needs to login. Once this happens I want them to be able to go back and forth between the two pages without having to log in when they switch servers. Page navigation is handled through myServlet.java so that when a user clicks on a link the request is forwarded on to myServlet.java where the servlet determines where to redirect the user to. The servlet uses
RequestDispatcher requestDispatcher = getServletContex().getRequestDispatcher(url);
requestDispatcher.forward(request, response);
to forward the user to the correct page. This works fine for the JSP pages but when I forward to www.netData.com/page2 I get an error telling me the address doesn't start with a /. I also need to send the user name and password for the net.data pages to avoid the second login window to popup.
I understand that the requestDsipatcher.forward() method directs the browser to a page that is relative to the current root directory. If I try to use response.sendRedirect(url) I get sent to the right page but the signon window pops up. I would appreciate any help.

The servers keep track of the user by storing a cookie on the clients computer. The cookie is only valid for the domain that created it.
So, to make this work you need to send the username and password as part of the sendRedirect. the forward() method won't work.
What you could do is create some code on the .net machine that accepts username, password and target URL as input. Once it receives those parameters it should perform the .net login procedure and redirect to the correct page.
In your servlet you should pass those parameters on to the .net machine and the user should get the correct page without ever seeing any login windows.
Make sure to use https if you decide to follow this scheme since http will transmit the username/password in cleartext.

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.

Issue in applying SSL selectively to Login JSP Page--Session getting lost.

Hi,
I am facing some issues with SSL configuration on my web site running on tomcat 5.5. I am using jdk 1.5 and form based authentication with JAAS framework.
The SSL configuration is working perfectly when applied to complete web site, but starts giving problem when applied selectively to some JSP pages. At present I am trying to apply SSL just on the login page.
When the login screen loads up, the URL in the browser has a protocol "*https*", as expected, but it doesn't gets changed to "*http*" once the user has successfully logged in. Why is the automatic change from https to http not ocurring?
Also I want to know which is the default page, tomcat will direct the logged in user to, once successfully authenticated using form based login; Is there any way to change this default page to some other page. It looks like that tomcat automatically directs to index.html , once the user has been successfully authenticated, but I am not so sure. My index.html page is having 4 frames; the source of these frames are different JSP pages, which are not under SSL.
My aim is to apply SSL just on login.jsp so that password doesn't travel in clear text. Once the user is authenticated he should see index.html and the address bar's URL should change it's protocol from https to http.

I have gone through the http://forums.sun.com/thread.jspa?threadID=197150 and tried implementing it; The filter as explained in the thread does gets called but the session values are still lost.
Please note I am using javascript to go from secure "https" to "http" once the user has successfully logged in The javascript code is as below:
top.location.href="http://localhost:8080/qtv/index.html." ;
If I use response.sendRedirect("http://localhost:8080/qtv/index.html") for going to non-secure mode, the index.html page does not gets loaded properly. (Please note that my index.html is made of *4 frames*, as explained earlier. This is a legacy code and frames can't be removed).
The reason for index.html not getting loaded properly is that the Address bar URL does NOT change its URL and protocol from https (https://localhost:8443/qtv/index.html ) to "*http*" (http://localhost:8080/qtv/index.html) when esponse.sendRedirect() is used ;this is the default behaviour of response.sendRedirect(). And because the protocol in address bar is https, index.html is not able to load the other JSP's in it's frames because of cross-frame-scripting security issues (The other JSP's to be loaded in frames are are NOT secure as discussed earlier).
Please let know if any way out.

Pls help me writing logic:iterate tag in jsp page

Hey guys , I am struck in retriving string p1,p2,p3 in the jsp page
Pls have a look ata the code
In DAO class:-
StdprdDAO.java
Public arrayList getPFP()
ArrayList a = new ArrayList();
While(rs.next())
     columnsVO colVO = new columnsVO;
     colVO.setProduct(rset.getString(1));//will store in String colProduct
     colVO.setFamily(rset.getString(2));//will store in String colFamily
colVO.setPrice(rset.getString(3));//will store in String colPrice
a.add(colVO);
return a;
In Action Class:-
ArrayList final = null;
StdprdDAO DAO = new stdprdDAO();
final = DAO.getPFP();
For(int i = 0; final !=null && i<final.size() ; i++)
     columnsVO VO = null;
     VO = (columnsVO)final.get(i);
     String p1 = (String) VO.getProduct();
     String p2 = (String) VO.getFamily();
     String p3 = (String) VO.getPrice();
     Request.setAttribute(p1,p1);
     Request.setAttribute(p2,p2);
     Request.setAttribute(p3,p3);
In JSP PAGE:-
id = columnsVO>
<bean:write name = columnsVO property=final id=p1>
but still I am doubting my above sentences in jsp page ,so pls correct them if possible.
Instead of l;ogic:iterate can I use directly getattribute(p1)? <logic:iterate
Still I m doubting I can not utilize columnsVO file in logic:iterate, I can utilize only formbean file.
So pls help me with this.

May I ask why have you done it?
If it is related to printing of the list then it is of no use.But it IS of use. The objects compEmployees is in scope.
It has the list we want to print out.
With logic:iterate:
<table>
     <tr>
       <th>Number</th>
       <th>Employee</th>
     </tr>
     <logic:iterate name="compEmployees" property="totalEmps" id="emp">
          <tr>
            <td>
              <bean:write name="emp" property="empNo"/>
            </td>
            <td>
              <bean:write name="emp" property="empName"/>
            </td>
          </tr>
     </logic:iterate>
</table>or alternatively with JSTL and c:forEach
<table>
     <tr>
       <th>Number</th>
       <th>Employee</th>
     </tr>
     <c:forEach items="${compEmployees.totalEmps}" var="emp">
          <tr>
            <td>
              <c:out value="${emp.empNo}"/>
            </td>
            <td>
              <c:out value="${emp.empName}"/>

Are your records javascript variables? If so, you can use a json formatter to serialize the records to a string and send it from PageA to PageB using mechanism that supports strings (i.e. query parameter, cookie, etc).
You can learn more about json at http://www.json.org/ and about a json serializer/parser at http://www.json.org/js.html .

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.
