check the tld file for jstl/core. there could be a possibility that forEach tag is not defined in there or may you are using older version of tag library

Hide the dropdowns while the "modal dialog" is displayed.

Use an iframe to contain the body of the "dialog".

P.S. Tell your powers that be that IE6 is deprecated and even Microsoft no longer supports it. Time to move on...

Yeah the iframe part worked for me.
Thanks.

Well I was facing the same issue as Amol had, but I removed the timeZone attribute from the <f:convertDateTime /> tag, and guess what I got it on the track.

Hi All,
I don't know whether its a stupid question or not, but I am a little bit curious about this.
So my question is can we change the location of a deployment descriptor in a web application from WEB-INF to some other place.
Can we move it outside the WEB-INF or can we put it inside any subdirectory of WEB-INF.

If yes then where should we have to mention it, so the container gets to know about it.

Thanks

OCP Introduction to Oracle9i: SQL
Exam Code 1Z0-007

The problem is simple buddy, the query syntax you are using supports Oracle 9i and higher. Its called ANSI/ISO Syntax. Instead of using this, try the older one, which most of the developers use to avoid the error.
It goes like this.

SQL> select e.ename, e.deptno, d.dname from dept d, emp e where d.deptno(+) = e.deptno;
This is the example of left outer join. The (+) operator is on the left side of the compare operator, if you put it on the right side you'll get the right outer join.

I hope this helps you out.

Hi all,

I guess I solved the problem. After posting the problem here I installed a FTP client, CuteFTP and did the same thing and i figured it out through the console that it was doing the same thing but for the response 125 which means data connection already open it was uploading the file. So i made the changes in my code and its working perfect.

The changes i made in the above code was at line 207:
so instead of the previous line
if (!response.startsWith("150 ")) { throw new IOException("SimpleFTP was not allowed to send the file: " + response); }
I changed it to
if (!response.startsWith("150 ") && !response.startsWith("125 ")) { throw new IOException("SimpleFTP was not allowed to send the file: " + response); }
Now I am going to write the download code, and as soon as i'll come up with it, i'll post it here.

Thanks Joe for the reply but I think that the problem is not with the code part, because I am able to make the connection. When I am trying to write the file then the reader gives the response for Access Denied.

Hi All,
I m working on a module in which I have to generate sales report and then transfer it to a server using FTP connection. The file generation part is working very well. I am using an open source FTP code known as SimpleFTP which I have modified a little bit.
The problem occurs while uploading the file. Its showing Error 125: Data connection already open; transfer starting.
Could any one please suggest me what is the problem. I am attaching the code snippet below.
The file path is hard coded for the test purpose.
The host, user name and passwords have been modified to xxx

I am looking for a light weight base64 encoder and decoder class that very small size because I need to use it with mobile application.

Thank you very much.

Hi all,
I m working on a module in which i have to upload an image, create its thumbnails and then display it. I m using struts2 copyFile() method for this. In the normal case everything is working perfect. Now I want to rename the actual file with the datetime stamp and then upload it so that i can distinguish two files. Here is the method i m using for it.
public String uploadImage() throws Exception { ActionContext ctx= ActionContext.getContext(); HttpServletRequest request= (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST); Date currentDate = new Date(); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String uploadedDateTime = sdf.format(currentDate); ServletContext servletContext = request.getSession().getServletContext(); String contextPath = servletContext.getRealPath("/"); try { if(uploadFile.length()!=0){ // The length of the file is zero when no file is browsed or selected. String uploadFileExt = getUploadFileFileName().substring(getUploadFileFileName().lastIndexOf(".")); String fullFileName =contextPath+"\\uploadimages\\"+getUploadFileFileName(); File theFile = new File(fullFileName); FileUtils.copyFile(uploadFile, theFile); String largeImageName="large_"+getUploadFileFileName(); String smallImageName="small_"+getUploadFileFileName(); String inFileName = contextPath+"\\uploadimages\\"+getUploadFileFileName(); String large_outFilename = contextPath+"\\uploadimages\\"+"/"+largeImageName; makeThumbnail(inFileName, 346,145, 100, large_outFilename); String small_outFilename = contextPath+"\\uploadimages\\"+"/"+smallImageName; makeThumbnail(inFileName,117 ,145, 100, small_outFilename); item.setLargeImageName(largeImageName); item.setSmallImageName(smallImageName); request.getSession().setAttribute("sku", item.getSku()); if(item.getActionName()!=null && item.getActionName().equals("edit")){ bookStoreService.updateEditedItemUpload(getItem()); }else{ bookStoreService.insertItemDetails(getItem()); } File file =null; file = new File(fullFileName); // Make sure the file or directory exists and isn't write protected if (file.exists()){ if (file.canWrite()){ if (!file.isDirectory()){ file.delete(); } } } } } catch (Exception e) { } return SUCCESS; }
You can see in the code i m using two variables uploadedDateTime for the time stamp thing & uploadFileExt which returns the file extension.
Now suppose if i m uploading a file abc.jpg from any location i want to rename it with uploadedDateTime.jpg and then upload it.
Now as the code show, I m also deleting the original file and leaving only two thumbnails on the system.
So I need suggestions or help. Mean while I m also trying & if i'll find any solutions i'll update it.
Thanks

thanks to all of you...
@Ashok The current cost is 3500/- but the scheme is valid till 7th of July, as i have been told by the NIIT

Playing mafia wars on face book and always try to apply my developer mind there..and guess what, most of the time i came out with glitches there which helps a lot in improving my skills in that game...its really really fun guys...

yeah i also got the same voucher, but i have been told that the scheme of 3500/- is valid till 7th of July, but from the counter i got the voucher with the validity of 30th June.
