JSP + Struts2

Hello,
I'm in a new project that needs to be in JSP. I'm using JSP + Struts2, do you guys think its good? Whats the best and the the most recent technologies to use with JSP?
I'm having a problem when passing JSP parameters values to Java Classes in IE8, with firefox and chrome it just works fine. Whats the problem with ie8 ?
Thanks in advance,
João

If You say that don't want to use jsp script and don't like javascript, there might a problem occur. These technologies are a basement of web development. Interest in GWT, the framework from google. It might be very useful for You, there's no jsp - everything is written purely in java and the whole web-app is written in AJAX, so there's almost no page refreshing. Of course there're some limitations but You can always write native code in javascript.

Pointers needed to create a JSP for week/hour calendar type component

Hi,
I am looking to get some pointers on how to create week/hour calendar type component in JSP.
My application is JSP/struts2 based web application. I need to create a web page where users will see a week hour calendar and for any time slot will enter some information. Each time slot can have different information. For example: Sunday 9:30am to 10:00am - Click on this cell and pop up a dialog for info and save it without refreshing the page. At the end combine all this info for each slot and submit to the server.
If there is already a component like this is available to use, please point me to that.
Any ideas are welcome.
Thanks,
Developer in need.

I dont know of an already existing application that can do this. However, here are some ideas on creating your own:
Create an html table in JSP who's number of rows and columns match what you would find in an ordinary wall calendar for the given month and year. Use the Calander.java class to obtain the number of days in the current month and build the JSP page accordingly (Calendar.java should automatically take care of leap year). You will probably need to add 'next' and 'previous' buttons to the form to retrieve the previous and next month(s) in case the user wants to access previous or future months. Each cell in the table displays that day (example ' 28 '). Notice my convention the first column is usually 'Sunday'.
Next, determine what to put in each cell. One suggestion is to embed a table in each cell with 48 rows (24 hours in a day, 1/2 hour resolution= =48), and two columns (first column is for time: example: "10:30am to 11:00am", the second column is for the user's appointment message).
Above that embedded table is the day (example: '28'). If a user has no information in the embedded table, the outer cell will appear to have nothing but the '28' in it.
Next, how to populate the cell. When the user clicks on the cell, have an onclick event call a javascript function. The function will pop up a new window (a child window) by calling 'window.open( )' (google 'window.open'). In the pop up, show a table with 48 rows, 2 columns that the user can type in a message within column 2. When the user clicks 'submit' button on the pop up, call a javascript onclick function that reads all the message cells. Any cell not empty will populate the corresponding cell (day, rowID, columnID) back on the parent window by calling something like this: window.opener.document.myFormName.myTextField.value = someValue
(google 'window.opener'). Once this is done, close the child window from that javascript function. By calling 'window.opener', you dont have to refresh the parent window.
Next, if the user clicks on the parent window cell that is already populated, you will have to pass all theexisting information for that day through the window.open( ) to the child window so the pop up child window will show that preexisting information (that way he can add to the cell or alter it as he pleases).
Next, after he alters many days on the calender, you have to provide an 'update' button on the parent form so the user saves his changes (write the data to a database record, with his name attached to that record). Note: if he clicks the previous/next button, he will lose any changes unless you also save the information before going to the previous/next page.
Next, you might want to provide a vertical scroll bar on the table cell if
the end user has many messages that cant be viewed in the parent cell all at once. Note each cell should be a fixed number of pixels width/height so it shows correctly. Have Fun!

Array of Fields in JSP page

hi,
i am just a biginer in java forum& application developement,
*********problem****************
I am using jsp+struts2 combination. one of my jsp page contains a select field to select number (n).
on basis of that selected number(n) I've to display n text fields.for every text field there is an submit button.
how it is possible? using arry index?

Yes, you can use the array notation in the name of the input element. You should end up with something like:
<table>
    <tr><td><input name="input[0]"></td></tr>
    <tr><td><input name="input[1]"></td></tr>
    <tr><td><input name="input[2]"></td></tr>
</table>
<input type="hidden" name="rows" value="3">You can use JSTL c:forEach with a varStatus for this.

Help a beginner start....

I'm looking into developing a website using either JSP or servlets. However, I have hard time starting due to the difficulty of identifying what I need. I very well versed with Java, but have little experience with JSP or servlets. My knowledge in JSP/Servlets come from reading a book briefly years ago. I have great knowledge of programming and understand web technology. I have programmed dynamic sites in PHP and ColdFusion.
What I'm trying to accomplish is a site that has the following attributes:
- create general classes that can be used across multiple sites i.e. database access class etc... (portable code) I intend to start with a small test site, but design it with a larger production web site in mind.
- prefer if they work with hosting companies (which probably limites me to JSP), but is not a requirement
- has an easily updated front end i.e. look and feel to site (Struts2 seems to fit this bill). PHP is extremely difficult to update the look and feel of a site. I suspect JSP would be the same....
I dabbled around with WebSphere and DB2 for a while, but got nowhere since it was rather difficult to get setup and started properly. So here are my questions:
1) What technology should I at least take a look at before making a decision? (I'm strongly considering JSP + Struts2 + Dojo, but many have recommended Google Web Toolkit)
2) What web server should I be looking at? (Tomcat, Websphere, JBoss.... I realise that hosting companies probalby use Tomcat)?
3) What do people use for small sites that could have been done in PHP, but like the extendability and backwards compatibility of Java? JSP or Servlets?
4) Where should I start? Should I start learning Servlets, JSP or Struts2? Any resources?
5) Do one need to know JSP or Servlets in order to take advantage of Struts2?
There seems to be very little information for people that jump from PHP to Java for web development. Any advice would be appreciated.... It has been a frustrating experience.

((((Use MVC (model view controlller) archtecture. You can use a central servlet to take in all url requests and dispatch to the appropriate jsp. Then you can use a framework such as Struts2 or Spring as an alternative to the cental servlet.

Struts2 and JSP

Hi All,
I am new to the struts2 concept but have to do a project in struts2 and jsp wherein all the user data from a textarea on a jsp page has to be stored in a file(doc, pdf or txt) on the users system using struts2. Can anyone please help me out with a sample code for it?
Thank You in advance.

An old fashioned way to add dynamic sorting is to use a group on a variable that reverses the letters of the text values depending on which column and whether user chooses Ascending or Descending. Does not even need SDK. The HTML export can be done using report parts but will not do well for full complex reports.
We provide both these features in our Dashboard Launch product seen on the Ecohub

I think we have a case here of trying to use the Struts1.2 tag libraries in Struts2.0
The tag libraries are quite different :-)
I believe the <s:textfield> tag is probably what was intended here?
Or install struts 1.2 instead of struts2 :-)

Can any one help me to download a file using struts2

can any send me a sample program to download a file using struts2

saradhi

i cannot find it in google please help me by sending a link or a code

Jsp flex chart

Hello
I would like to create a horizontal bar chart according to data from a struts2 action class and place the flex chart in a jsp.
I have already seen code on how to do a horizontal bar chart @ http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Live Docs_Book_Parts&file=charts_types_109_03.html
I am watching James Ward's video on java and flex @ http://www.jamesward.com/blog/2008/07/21/video-flex-and-java/
How do I place the flex graph in my jsp? What kind of flex project/component do I create and where do I place it?
Appreciate all help.
Thanks

Once you compile your Flex app you can size it and embed it anywhere you
want in your web page.

Struts2 and Tiles2 - Error executing tag: Attribute 'title' not found.

I keep getting Error executing tag: Attribute 'title' not found when I go to the baseLayout.jsp page. I am figuring it is not seeing the tiles.xml file, but I have placed it in the /WEB-INF directory like every web page I have found says too. Any help or pointers would be appreciated.

I was playing around with it some more and was trying to follow this page:
http://www.vaannila.com/struts-2/struts-2-example/struts-2-tiles-example-1.html
I made sure I had the same jar versions. I still get the same exception in the Browser, but I get a few more log messages in the tomcat log;
Obviously I have something configured wrong. I'll see what searching brings up, and of course any help would be appreciated.

Dynamic row in STRUTS2

dear java,
Help needed for updating an list in jsp with values added as dynamic row in STRUTS2.
I have a table displaying data from list (<s:iterator>). It displays 2 rows. I have a button which on clicks added one more row.. blank row (consists, textfields).. in which data is added. now on submit, i need to update list.
Any help would be much appreciated!

tnx friend.,
anyway i got the result.
instead of using <s:textfield name="textFields[0]" />, i have replaced for (within JS method)
<input type='text' name='locationId[" + num + "]' value='' id='dyamicRowAction_locationId_" + num + "_'/>
(its actual replacement html tag for S2 tag - get it from view source ).

Crystal Report Images Not Showing - JSP inside /WEB-INF folder

Hi Experts,
I am using Crystal report for Eclipse and also using Struts2 and tiles framework combination.
The problem is when viewing the report all I've got is red X on all images and the graph image also not showing. This is when I use tiles and my jsp is inside the web-inf folder.
This is my struts link: href="s:url value='/report/reportOpen.action?report=1'
I've checked that the path to the viewer generated HTML is not correct. see code below.
src="../../../crystalreportviewers/js/crviewerinclude.js"
But when I test to access a simple jsp viewer that resides on the web root folder, this works fine but of course this is not what I want to have. I need to have my banner and menus on top of the report page (using tiles)
This is my jsp link: href="s:url value='/ReportViewer.jsp?report=1'
Viewer generated HTML below.
src="crystalreportviewers/js/crviewerinclude.js"
This might be a common problem and that you can share to me your solution.
Note: I removed the script tags because I can't submit this entry.
Thank you in advance,
Regards,

Crystal Report Images Not Showing - JSP inside /WEB-INF folder

Hi Saravana,
After a few experimentation from your idea i was able to figure out the problem and now it is working.
I don't have to copy the folder to where my jsp resides but still maintains it in the root location: web/crystalreportviewers
The changes should always be in web.xml.
1st: change the crystal_image_uri value to ../crystalreportviewers
2nd: change crystal_image_use_relative value to "web"
Change to "web" instead of webapp because that is what I named my web root folder.
<context-param>
          <param-name>crystal_image_uri</param-name>
          <param-value>../crystalreportviewers</param-value>
     </context-param>
     <context-param>
          <param-name>crystal_image_use_relative</param-name>
          <param-value>web</param-value>
     </context-param>
Thank you. You showed me the way on how to solve the 3 day problem.
BTW, my next problem is when clicking on any buttons prev/next/print/export, I got this error HTTP Status 404.
Well, at least for now I can view my initial report. I just need to figure out the next issue and with the help of the great people here in the forum.
Thanks a lot.
Regards,
Rulix

Can't get EntityManager access in JSP/Servlet

Hi all,
our team has started a EJB project (EJBs + JPA configurations)
we managed to access the configured JPA (EntityManager etc) within the EJB instance; however we don't know how to access the EntityManager within JSP/Servlet
Our project's structure:
1 EJB project (EJB classes, EntityBean classes, JPA configuration + eclipselink)
1 Web project (for JSP, Servlets)
the main problem is ... we can't access EntityManager(s) in JSP / Servlets (and we already tried using Struts2.0 to replace servlets/jsp... the problem is the same... so it is not ... the matter of choosing the view technology...)
Jason

Hi Jason,
How i tried to get EntityManager is as following:
Suppose I want to define my Persistence unit like Following:
*<Your-EAR>/APP-INF/classes/MyEmployee.java*
"*MyEmployee.java*"
package entityA;
import java.io.Serializable;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;
import javax.persistence.*;
@Entity()
@Table(name="MYEMPLOYEE")
public class MyEmployee implements Serializable {
     //default serial version id, required for serializable classes.
     private static final long serialVersionUID = 1L;
     private Long empno;
     private String empname;
public MyEmployee() {
     @Id()
     @Column(name="EMPNO", unique=true, nullable=false, precision=22)
     public Long getEmpno() {
          return this.empno;
     public void setEmpno(Long empno) {
          this.empno = empno;
     @Basic()
     @Column(name="EMPNAME", length=15)
     public String getEmpname() {
          return this.empname;
     public void setEmpname(String empname) {
          this.empname = empname;
     public boolean equals(Object other) {
          if (this == other) {
               return true;
          if (!(other instanceof MyEmployee)) {
               return false;
          MyEmployee castOther = (MyEmployee)other;
          return new EqualsBuilder()
               .append(this.getEmpno(), castOther.getEmpno())
               .isEquals();
     public int hashCode() {
          return new HashCodeBuilder()
               .append(getEmpno())
               .toHashCode();
     public String toString() {
          return new ToStringBuilder(this)
               .append("empno", getEmpno())
               .toString();
