Hi,
I'm trying to upload a file using <input type="file" ... >
my form is like <form name="someName" enctype="multipart/form-data" .... >

This is working fine with IE on Windos but , causing problem with Safari on Mac machine.

Also, if I don't upload any file and click on Back button in my page, it throws an exception "file size unknown"

If I remove "enctype" entry from jsp-form , back button functionality works fine but file upload fails.

Any help for this behaviour???

Thanks ..

Hi,
I'm caught into a strange problem. Is there some issue with IE7?
My problem :

I have a file input element in my page. When I select an image, I want to display the selected image in a span. I have tested and found that my code works fine with IE6 but does not show up the image in IE7. It only shows default "image not found" icon.

I'm invoking js function on onchange event of file input.
My code :
var innerhtml = "<img height=60 width=60 src='" + imgName + "'>"; document.getElementById("thumbnailImage").innerHTML=innerhtml;

is there anything wrong with this code?(the code is working fine for IE6, but causing problem in IE7)

Thanks for spending your time.

Thanks Ulf, Thanks a lot for your help.

hi,
I'm writing some PDF files using iText.In general it's fine, but , is there some way I can attach my css to the pdf to avoid lot's of coding and parsing for html tags and rendering them?

Thanks for spending time for me.

Hi Ben,
Thanks for giving a look at the problem.

To explain you further,

On In my page I've a file component (file uploader).
Once I select a file, I want to have a lok at the file first, using a link preview for that.

The above code is rendered inside a div component.

This works fine if i'm editing the page ( the file is there in ftp server and the file name is there with my jsp), before I select new file for preview.

sending you code snipet again with additional info...

var vidstring =' '; vidstring+='<center>'; vidstring+= "<object classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" codebase=\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0\" >"; vidstring+= "<paramname=\"movie\"value='${urlStr}${cardFilePath}"+cardFile+"'>"; vidstring+= "<param name='quality' value='high' />"; vidstring+= "</object>"; // Insert our HTML and display the file. _vidPane.innerHTML=vidstring;

here _vidPane is just a div and is used to render the preview of the file.

Hope , this time I could make it more clear.
Thanks again.

Hi All.

Have not much experienc ewith GWT , but just have some Idea about it.

used while iterating thru the columns for export...
Thanks...

Hi,

i'm using displaytag. trying exporting data.
In my table , there are some columns which are generated at runtime .
When starting export , getting unusual results:
1) Total number of columns is reduced by 1 ( i.e. n-1)
2) Object value = column.getValue(this.decorated);

if this.decorated is true , getting only columns which NOT generated programatically, else getting only those columns which generated programatically and rest of the columns are coming as null

would welcome any hint/help .

Thanks

Hi.

How could we find out the host IP requesting for some resource or service in the net? need to find out the Ip of host which is not in local LAN.

Thanks .

Hi.

I've written a TLD for rendering dropdown in jsp page .
The tag takes Map with key / value in it for rendering the list.
optionally we can pass key / value to display as selected item.
here is the sample jsp code snipet :

<html:select property="countryList" onchange="javascript:checkCountry();"> <% String country=""; country=(String)countryMap.get(countryId); if( null != country && ! country.equals("") ){ %> <util:list data="<%=countryMap%>" key="<%=countryId%>" value="<%=country%>"/> <%} else { %> <util:list data="<%=countryMap%>" /> <% } %> </html:select>
the first one renders dropdown with some data selected and the other without selection.

The problem is, when I reset my form , the dropdown is with no selection , regardless of it contained some data initially or not.
I wanted to retain the data in case it was there .

here is the code for tld ..
public int doEndTag() throws JspTagException { try{ Collection values= data.values(); String [] valuesArray = (String [] )values.toArray(new String[values.size()]); Arrays.sort(valuesArray); pageContext.getOut().write("<option value=\"\" selected >Select</option>"); for(int i=0; i<valuesArray.length;i++){ Set entrySet = data.entrySet(); Iterator itr = entrySet.iterator(); while(itr.hasNext()){ Map.Entry entryObj =( Map.Entry)itr.next(); String key =(String) entryObj.getKey(); String value = (String) entryObj.getValue(); if(value.equals(valuesArray[i])){ if (key.equals(getKey()) && value.equals(getValue())) pageContext.getOut().write("<option value=" +key + " selected> " + value + "</option>"); else pageContext.getOut().write("<option value=" +key + " > " + value + "</option>"); break; } } // end of while }// end fof for }catch(IOException ioe){ throw new JspTagException ("JSP TAG ERROR..."); } return EVAL_PAGE; }

what could be the possible reason ?
some help pls.

Thanks.

Hi Merrill,
Thanks for your response.

Actually , the problem I told starts after download is completed.

After d/l when I try fire some other action, nothing happens .
If I choose to OPEN the file , or CANCEL , my program works normally.

Also, I've a link to NEW page in my that jsp only , and a dropdwon list.
The link merely opens a new jsp , but ,onchange ,dropdown fires action .
After saving the D/L file , when I start with NEW link it is alright.
but , If I try with dropdown , it causes a js error saying ACCESS is denied.

If , I try wotking with other actions from my side menu, nothing happens .
not even simple jsp links work.

Hope , it is better to understand now.

Thanks again for giving some thought for my problem.

Hi.
i'm trying to download a file ( using streamOutput ) .
I'm able to download file successfully.
When i choose "Open" file or 'Cancel" when prompted , things go fine , but when i choose "Save" , file is downloaded successfully , but further no action is being executed.

Using trace i could find that actions fired but not Invoked ( not showing any jsp forwarded from action , nor executing the body of action ... only able to trace which is action is fired )

Showing up what I have in my code =======

struts-config --

<action path="/populateCSV" name="xlsDataForm" scope="request" type="XlsDataAction">
</action>


=================

Action --

public ActionForward populateCSV( ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { CSVWriter csvWriter = new CSVWriter(); StringBuffer buffer = csvWriter.generateCSV(); // buffer contains data to be written to the file ... // write the buffer into .csv file.... prompt for download response.setContentType("application/octet-stream"); response.setHeader("Content-disposition", "attachment; filename=directoryData.csv"); ServletOutputStream fOut = response.getOutputStream(); fOut.write(buffer.toString().getBytes()); fOut.flush(); // Done deal. Close it. fOut.close(); return null; }


=================

Also, if i click some url in the page ( that I do have in my page ) , It starts working normally. ( the url must not be another Action (.do) . This is doing fine for jsp in url .

Please help .

Thanks and regards,
