Servlets :: CSS Stylesheet Will Not Work With JSP Files
Feb 11, 2014
Why I can't get an external style sheet work work when using JSP files? Putting a link in the doc head like I would for an HTML or PHP file does not work. The style sheet is in the exact same directory as the JSP files and I cannot get it to work. I think I have tried about everything that has been suggested on the web with no luck.
If I create an HTML doc in the same directory as the JSP files, and add the below line in the document head, it works fine. Doing the same thing with a JSP file does nothing.
After confirmation to the login details I added new cookie having logging information and then dispatched this request to controller servlet where this cookie is checked if it is present then user is forwarded to a particular page. Otherwise is redirected to the sign in page. Now the problem is when we add cookies then it is added into "response" object and when we get cookies we get them from "request" object. So for the first time redirection to controller servlet "response" object would not have this cookie as it is not available in "request" object. But will be available for later requests.
My question is what is the way to get this cookie in the first request. Or is there any way to send refresh like response to the browser so that this cookie is added??
Okay I am new to web-programming in general and am confused about how sessions work-:
1) Are sessions stored only on the client computer ? If so then if cookies are disabled then if browsers only store the session how are they able to remember the exact JSESSIONID ? Also how does the server (like Tomcat) remember which JSESSIONID belongs to which user ? Where does it store that information ?
2) If the server also stores the session information then how fast does it become out of date ?
3) If a client has cookies disabled does the server maintain a key-value pair of the IP and the session-id, so that if the same client logs in then the same session-id will be appended ?
4) When does the web-container make the decision of using cookies or the encodeURL() method to embed the session info ?
I am using servlet 2.4 I used the ff. code below to set httponly in my application's cookies but it did not work. When I do a javascrip alert (document. cooke) in my page, the session id still shows up.
How can I set the default stylesheet for a user control that I have created? I want to make the control available for anyone to use and I want it to use a stylesheet by default without the user of the control having to do anything. I also want it to be possible for the user of the control to override the definitions set on the default stylesheet if he wants to.
I would like to know what is the best way to upload & download files using Servlets/Jsp's . In some websites I have seen example using third party API(by oreilly). Is it better to follow any third party or can we do it just by using I/O streams. What are the steps of uploading files. And where do we need to store files once the user uploads ,Database or server??
We have a website used for downloading large files as large as 6gb and sometimes larger. We have all files in FTP server. The websit is JSP/Servlet /Tomcat combination. Below is code sample. I need a solution to increase the download speed. I understand it is bound to network bandwidth but are the steps that we need to take while we have such large files.I read about multipart downloads,gunzip streaming.
//first connect to FTP server and login and keep connection Calendar cal=Calendar.getInstance(); startTime=cal.getTime(); fis=ftp.downloadFile(ftpclient,separator+resourceID); response.setContentType("application/*"); response.setHeader("Content-Disposition", "attachment; filename="" + downloadFileName + "";"); byte[] bytes = new byte[1024];
When I map my servlet to the ROOT of the site, the javascript, CSS and image files are not served. The conversation between the server and browser shows the files are being sent, but they are not rendered in the browser. This happens in both Firefox and Chrome.
If I change the mapping to anything other than the root, such as /x/, everything works as it should.
I wrote a code to download a zip file in jsp, but it is not working as expected, when i execute this following program i am able to download file with "download_all.jsp" name, but now original download file (/tmp/Download_All/1244687508907.Zip). The download_all.jsp is my jsp name which is having the following code. Here is the code snippet:
try { String filename = "/tmp/Download_All/1244687508907.Zip"; if(request.getParameter("filepath")!=null){ filename=request.getParameter("filepath"); } // set the http content type to "APPLICATION/OCTET-STREAM response.setContentType("APPLICATION/OCTET-STREAM");
In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){ try { BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt")); Random rand = new Random(); int low = rand.nextInt(400); String fil=""; int i=0; while(i!=low){
[Code]...
The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?
I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
The problem is as follows: I've been running java script using git bash and at one point it tells me that I need to increase heap size because apparently it takes more than 1gb to run. However although I manually increase it via control panel>programs>java nothing changes. I've been told that I need to ' figure out how to use 64bit java (and a VM that supports 64bit) in order to increase the maximum memory allocation (heap size) to something north of 2g.'
My laptop has 8GB worth of RAM (Windows 7)so it shouldn't technically have problems running anything above 1G. But there is apparently a 1GB wall But increasing the heap size to above 2G results in an error stating that VM doesn't initialize within git bash, I thought that my java is 32 bit so I downloaded a 64 bit java. Now how and if it is even possible to allocate a program to run under 64 bit java and if I should delete the other java version.
1) Instead of showing 0K 5K 10K, I would like to show the country names (A - D), with no number or tick. I figured out this one by just commenting out all the codes relating to ticks.
2) Place the country names in the center of the arch. I don't know how to do this one.
I've got a panel which an arbitrary number of text fields may be added to at run time. I've got it set up so that the window's height, and the height of the panel in which the fields appear will never exceed the height of the screen.What I don't have is a way to make the panel scroll to access the fields that are being visually truncated. I'm setting the autoscrolls on the panel to true, but when I run the program, the fields are simply truncated.
So I'm working on a project and noticed that my toString() method won't work. This is just an example of the type of code that I have in my real project. THIS IS MY MAIN CLASS
XML Code:
package trialanderror; import java.util.Scanner; public class TrialAndError { public static void main(String[] args) { Scanner keys = new Scanner(System.in); String name; String phonenumber;
I want to create a dropdown menu with contents from a database. You can see my Code in the attachment. It does not work, but why? I have a dropdown-symbol, but no contents.
I use Chrome rather than IE. Recently I got an error message when I tried to deposit a check online.
It said that I needed up get a newer version of Java than 6.10, so I downloaded 7u51.
When I tried to deposit the check again, Chrome asked if I wanted to run the app, and I said yes, but that took me back to the download link again.
I spent almost an hour with my bank experts, but they were unable to solve the problem.
When we tried it on Internet Explorer, it worked fine.
Later, I discovered that on the Java Control Panel under the Default Browser for Java, it has only IE and Mozilla, with the IE being checked and greyed out.
I'm assuming that's why the problems on Chrome, even though up until a few days ago, I was able to deposit checks using Chrome-Java.
All I am trying to do is to make a section of code execute if two strings are equal. The two strings are userId and "A001062". When I use the debugger in Eclipse, I can see the value of userId as "A001062" but whatever string comparison I try never evaluates to true. I have tried
userId=="A001602" userId.equals("A001602") "A001602.equals(userId) Assigning A001062 to a string called AAA and comparing userId to AAA
My code is as follows. I have also attached a screen shot from the Eclipse Debugger which makes me think the string comparison should succeed. I never see the debugger execute the print line nor do I see the print line on the JBOSS console.
String userId = StringUtils.trim(nextLine[HR_USER_ID]); String AAA="A001062"; if (userId.intern().equals(AAA.intern())) {System.out.print("MKP1: " + userId+"-"+managerId);} if (userId.compareTo("DTS0428")==0) {System.out.print("MKP2: " + userId+"-"+managerId);}
