Re: How to access a map in jsp

[Christoph Nenning]

What are the types of antibioticId and organismTypeId ?
Are they primitive integers/longs?
I would add methods to DTOs to get them as Strings.


I suggest to store the list in a pageScope variable, to make the 
expression better readable.
There should be no dot before the bracket. You wrote "oaMap.[", it should 
be "oaMap["

How to access a map in jsp

[Yaragalla Muralidhar]

Hi,
 the following is the code in action class

//_
private List antibiotics;
private List organismTypes;
private Map> oaMap;
@Override
public String execute() throws Exception {
try{
antibiotics=dtService.getAllAntibioticsList();
organismTypes=dtService.getAllOrganisumTypes();
oaMap=dtService.getAllSelectedOrganismTypeAntibiotics();
}catch(Exception e){
log.error(e.getMessage(), e);
return "error";
}
return SUCCESS;
}
//_

The following is the code in jsp




checked  value='' style="line-height: 35px;" />




//__

i am trying to get the arrylist from the map and trying to check whether it
contains a particular string but this is not working? is this the right way
to do this? If not how to do this?

*Thanks and Regards,*
Muralidhar Yaragalla.

With struts1 you can use JSTL EL, too. The form bean names are available 
in EL. And struts1 has it's own tag lib.

replace Java scriptlets in JSP page

[Albert Kao]

The following Java scriptlet code in a Struts jsp is working fine. 
However, is it possible to change the jsp code so as to remove all the Java 
scriptlet codes? 

The .jsp code is like this:<%
  HttpSession httpSession = request.getSession(true);
  MyClient myClient = (MyClient)httpSession.getAttribute(MyConst.MY_CLIENT);
%>

  <%
    pageContext.setAttribute("requiredIndex", myClient.getRequiredIndex(index), 
PageContext.PAGE_SCOPE);
  %>
  
     <%= myClient.getNumber(index) %>
  

  
    
  
    
    
  
    
    
  ">
    
  
    
    
  



The java code is like this:public class Owner implements java.io.Serializable {
    private static final long serialVersionUID = 7920764268572909394L;
    private String lastName;
    private String ownershipCode;
    //...
    
    public Owner() {
    }

    // getter and setters
    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    //...
    public Integer getRequiredIndex(Integer index) {
        Integer requiredIndex = index;
        if (OWNRSHP_PARTNER.equals(ownershipCode)) {
            requiredIndex = requiredIndex - 1;
        }
        return requiredIndex;    
    }

    public String getNumber(Integer index) {
        String number = Integer.toString(index + 1);
        if (OWNRSHP_SOLE.equals(ownershipCode)) {
            number = "";
        } 
        return number;    
    }

Re: put ArrayList to s:hidden in jsp?

[umeshawasthi]

You can not do this directly as hidden field is used to store only a value

You need indexed field to store those value

I am not sure why you want to do this as more information can help others to 
provide some solutions

Is there a way to put hidden ArrayList in JSP please?

For example in a.jsp:



In action java class:
private ArrayListarraylist1 ;

So that abean.arraylist1 could be retrieved by action java class.

Dynamic Attributes ? I cannot find more info, just this [1] but I'm

Hi,
If I want to have an additinal attribute, say, in a textfield tag, in a

text.ftl:

- can it be done without extending the tag library?

Re: Struts2 resource property and dynamic population of action in jsp file

[Sachin Lale]

Thanks Dave.
I am using Struts 2.2.3. For #2 question i have a common jsp which is 
used for both Add and Edit operation. So on the basis of whether it is 
add/edit i want to set appropriate action.
Well one tweak just now came in my mind is to set the action name in 
request scope and use this as OGNL in setting form action.


Best regards,
Sachin

Nope; you can use the "key" tag attribute to define the property name
and label key at once.

JSP:
Resource: name=Full Name


2. I want the 'action' property of s:form tag to be populated dynamically.
For this i added a instance variable in my action 'onsubmitAction' and

Not sure; I might consider doing this a different way, though, perhaps
through a custom JSP-based tag (possibly a thin layer over an existing
tag).

(Why that way? I find it more informative, and it allows some
interesting games to be played.)

In any case, which version of S2 are you using?

Actually, it would have been good to note that the contact information

Yep.

Do the templates use the same models as the web layer? If so, seems
like direct rendering would be *much* more efficient.

Re: Velocity Inclusion in JSP

Seems like a JSP-based custom tag would be the easiest, but I don't
actually know what your template requirements are, so it's tough to
say.

What's the use-case?

Velocity Inclusion in JSP

[Biesbrock, Kevin]

There seem to be plenty of documents outlining how to include a jsp in a
velocity template, but not the other way around.  I am having a
difficult time finding information on how to include a Velocity template
in a JSP.  I recognized the s:component tag could work, but my templates
are not currently in my template (or "theme") folder and I feel like
they don't belong there because they are specific to my app, not the
chosen theme.  I don't have enough time with the schedule of our
application to go back and convert all of the JSPs to Velocity
templates.
 
So one solution I thought of would be to create an action that returns
the Velocity result...but I don't really know how I feel about this
approach:

/WEB-INF/myVelocityTemplates/{1}.vm

 
I would appreciate any guidance on this.

Re: retaining the values in html:select multiple="true" in jsp + collection + struts

[Dave Newton]

No; you'd need to re-load the contents/selections either in page load,
like normal, or on document ready via Ajax.

Re: How to set the value of request scope in a interceptor and get it in jsp?

[Li Ying]

Hi lunch716:

For more detail information about this issue,
you can read these documents:
  http://struts.apache.org/2.2.1/docs/ognl.html
  http://struts.apache.org/2.2.1/docs/ognl-basics.html

And in [ognl-basics.html], it says:
  "#request['foo'] or #request.foo"
means
  "request attribute ['foo'] (request.getAttribute())"

So i believe that "#request.key" and #request['key']
should work both.

How to set the value of request scope in a interceptor and get it in jsp?

[lunch716]

Hi,

When I set a value in my interceptor,I could not get it in a jsp.
How to do that?


### my interceptor
public class HogeIntercepter extends AbstractInterceptor {

   @Override
   public String intercept(ActionInvocation invocation) throws Exception {
  HttpServletRequest request = ServletActionContext.getRequest();
 
  request.setAttribute("key", "aaa");
 
 return invocation.invoke();
   }
}

### jsp
 -> it's return 0.
 -> it's return 0.
<% out.println(request.getAttribute("key")); %> -> return "aaa"



FYI.
I also refered the following the URL
http://stackoverflow.com/questions/1804266/struts2-understanding-the-value-stack
but I could not get it in a jsp. 

   public String intercept(ActionInvocation invocation) throws Exception {

 Map map= new HashMap();
 map.put("key", "aaa");
 invocation.getStack().push(map);
 
 return invocation.invoke();
 
}
Thanks.

how about if you change the location of the xml file, take it out of

Thanks for quick reply Brian.!

I tried adding new timestamp as parameters which generates new number

Even added those headers setting for no cache...

Re: XML file reloading in JSP (Caching issue)

[Brian Thompson]

What extra parameters have you added to the request?  AFAIK the
standard solution to this type of "improper caching" problem is to
simply append a random number or a timestamp to the request URL.  It's
an ugly hack, but it does work even when the headers don't seem to do
the trick.

Of course, the "Right Way" is to rely on the no-cache headers, so you
might want to do a bit more troubleshooting on that front.

Hope this helps,

-Brian

XML file reloading in JSP (Caching issue)

[XML User]

Hi,

I am running into an issue of caching. 

I have a jsp which generates the tree view from an XML file. This XML file
are loaded when the jsp is loaded. So whenever I add new child to the tree
view the xml file is updated by action class and the request reloads the jsp
page which in turns reload that updated XML file.

The issue is everytime it reloads the XML file, it gets from the temporary
internet file which is not getting updated until I kill the browser and
reload it.

For example.

For the first time, I have the xml file with content
.Parent 1
...Child 1
...Child 12
...Child 13
.Parent 2
...Child 2
...Child 21

When I call the action,to show tree then it calls the jsp file which loads
the XML file and shows the jsp tree which works perfectly. Shows complete
tree view based on XML file.

Then I will add new child "Child 22" into ".Parent 2" then the action will
be called and that action will update the XML file which is located into
"../WEBINF/pages" and returns to the same jsp and reloads jsp which also
needs to reloads the updated XML file.  

Now issue is , its not reloading that updated XML file and still showing the
tree without newly added child. When I checked internet temporary files, it
was still old XML file but at "../WEBINF/pages" location, the XML has been
updated. So I figured out that it is an issue of caching.

I tried to remove caching with http headers setting
<%
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy
server
%>

Also tried with adding extra parameters to change the URL request.

But still doen't work.

Anyone has any suggestions, what to do next.

Thanks for your help.

Sorry.., If any typos or explained in too much detail.

Simple answer: Call the appropriate setter method of your form bean in 
the JSP.
Less trivial options exist but depend on what you are trying to 
accomplish, your Struts version etc., none of which you elaborated in 
your original posting, hence my short reply :-)

load dynamically created files in jsp

[Upasana Sharma]

Hi

I have a scenario where i create a temporary dynamic image file from the
database and try to show it on my jsp.
The file url shows the image properly, but when in jsp , my browser says
that "Firefox doesn't know how to open this address, because the protocol
(d) isn't associated with any program"

the url i get is like

D:\myWorkspace\ui\WebContent\images\JavaTemp2261198016333434327.jpg, that is
my struts project folder.

How can i make the image accessible to my jsp.

problem in struts 2 tag in jsp calling spring bean

[Supratim Bandyopadhyaya]

Greetings to all,

I have a spring dao class like this

public class RoleDaoImpl extends SimpleJdbcDaoSupport implements RoleDao {

public Role findRoleById(Long id) {
  .


and I have added it to spring as






when I am calling a method in this dao from struts 2 tag
like this ... (this is a direct jsp call, not forwarding from an action)



this select list is not populating. How can I fix this.
I am using struts spring plug-in by the way.

Thanks in advance.
Supratim.

RE: Displaying an image in JSP in struts+tiles project

[Aruna Ponaka]

I wrote an action class and it worked. 
I called the action class like below...

img src="

and the struts.xml 

 
 
   books
 


ImageAction.java


import java.io.OutputStream;
import java.sql.Blob;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class ImageAction extends ActionSupport {

private static final long serialVersionUID = 1L;
private byte[] img=null;
private int id = 0;
Blob image = null;
   Connection con = null;
   Statement stmt = null;
   ResultSet rs = null;
   byte[] imgData = null;
   OutputStream o = null;
   HttpServletResponse response = ServletActionContext.getResponse();
   
public String execute() {
try {
Class.forName("com.mysql.jdbc.Driver");
  con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","test");
  stmt = con.createStatement();
  rs = stmt.executeQuery("select * from books_tb where
category='Social and Economic' order by publish_date desc");
  
  while (rs.next()) {
image = rs.getBlob(10);
imgData = 
image.getBytes(1,(int)image.length()); 
  } 
  
response.setContentType("image/jpeg");
System.out.println("id   "+getId());
OutputStream out = response.getOutputStream();
   out.write(imgData);
out.close();
return null;
}
catch (Exception e) {
  System.out.println(e.getMessage());
} 
return null;
  }


I was using doDefault function earlier and was trying to return the
outputstream, but that will not work and it should return null.

Hope this is useful to someone....

RE: Displaying an image in JSP in struts+tiles project

[Kawczynski, David]

Being a fan of the KISS policy... I played around with 
this but didn't have the time to figure it out, so I 
made the URL spat out by struts2 points to a servlet 
instead of struts2.  

(Note that my web.xml has struts2 configured to listen 
for *.action rather then slash-star)

Good luck & please let me know what your solution is.

Thanks!

Displaying an image in JSP in struts+tiles project

[Aruna Ponaka]

Hi,

Am building an application in struts2 and tiles. My requirement is to
retrieve an image blob from mysql database and display the image in a jsp
using img tag as below..

img src="" 

Part of my struts.xml is as below:

 




 

 

My MyBytesResult class is:

public class MyBytesResult implements Result {

private static final long serialVersionUID = 1L;


public void execute(ActionInvocation invocation) throws Exception {

MyAction action = (MyAction) invocation.getAction();
HttpServletResponse response = 
ServletActionContext.getResponse();

response.setContentType("image/jpeg");
//response.setContentLength(action.getMyContentLength());

response.getOutputStream().write(action.getMyImageInBytes());
response.getOutputStream().flush();
}

}

And MyAction class is:

public class MyAction extends ActionSupport {

private static final long serialVersionUID = 1L;
Blob image = null;
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
byte[] imgData = null;
OutputStream o = null;
HttpServletResponse response = ServletActionContext.getResponse();
public String doDefault() {
System.out.println("doDefault()");
try {
  Class.forName("com.mysql.jdbc.Driver");
  con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/project","root","pass");
  stmt = con.createStatement();
  rs = stmt.executeQuery("select * from books_tb where
category='General' order by publish_date desc");
  while (rs.next()) {
image = rs.getBlob(11);
imgData = 
image.getBytes(1,(int)image.length()); 
 } 
   }
catch (Exception e) {
  System.out.println(e.getMessage());
} 
return "myImageResult";
  }

  public byte[] getMyImageInBytes() { 
  System.out.println("getMyImageInBytes()");
  try{
  
  }
  catch (Exception e) {
  System.out.println(e.getMessage());
 
 } 
  return imgData;
  }

//  public String getMyContentType() { }
//  public String getMyContentDisposition() {}
//  public int getMyContentLength() { }
//  public int getMyBufferSize() { }

}

when i run the code the image is not displayed and I get an error saying
No result defined for action com.action.MyAction and result success

In struts.xml is I provide reslut name="success" and the jsp, it does not
throw an error but not displaying the image. However in any case it is not
going to MyAction.java. What could i do to rectify this?
Could provide you with required code if necessary..

Thanks,
Aruna

Ohh ok, thanks. I googled about that and i found that i can add a variable
or Object to page context with this:

pageContext.setAttribute("obj", obj);

That's because creating an object in a scriptlet doesn't mean it will
be in the page context, you need to actually add it to the context.

Question about OGNL in JSP

[Oscar Calderón]

Hi to all, this is my first question here. I have a doubt about the use of
OGNL expressions on JSP to access to an object that i declared in a
scriptlet in the same JSP.

I have the following code:

<%
   AnObject obj = request.getSession().getAttribute(AnObject.OBJECT_NAME);

%>


visitor


something else


I read in some books that when you call attr it searches in the page and
other scopes to find the variable that you specify, in my case obj, but it
doesn't find it. This is the right way to access to that object?

Wrong data being displayed in JSP page

Hello everybody!

I am new to this forum.I am using Struts 1.
This is my jsp page.










  :

Map vals = (Map) tariffCategoriesList.get(i);




<%=vals.get("description")%>

  : 





' name='tariffCat' value="<%=vals.get("tariff_Category_Id")%>"/>





<%

}

%>
















I am facing a strange problem in my application.
In the JSP Scriplet tag you could see that I am dynamically 
creating a few html text input with the help of a for-loop
When using <%=vals.get("description")%> its display the correct data on the
page(As no html elements is being used). But when I want to display the
value in ' name='tariffCat' value="<%=vals.get("tariff_Category_Id")%>"/>..
It displays the data from the bottom 5 struts html properties and not the
correct value from the List,i.e, value of















Can someone please help me out and explain why these things are happening in
my application?
F1 please..

We are using struts with hibernate to develop our application. What we

while inserting image ,we insert the path in the database and have

the webapps.the image is not been loaded after uploaded.. once after
restarting the server the image gets loaded.

We were using session factory for saving and retrieving images.

If there's a back-channel conversation that isn't being posted to the

Re: How to access enum in jsp?

[Bill Bohnenberger]

Ah ha! So when code the test attribute like this:

test="%{state == @com.yata.yata.actionst...@list}"

it works. Thanks, Pawel!

P.S. That syntax sux :-)

Re: How to access enum in jsp?

[Paweł Wielgus]

Hi Bill,
You are comparing string with enum by == operator, so it's always false.
Also if You see this value in debug it's the effect of toString() method.
You can access enum like this com.something.actionst...@none
if i remebmer correctly.

Best greetings,
Paweł Wielgus.

How to access enum in jsp?

[Bill Bohnenberger]

How do I reference an enum variable in an  test attribute?
This is the situation, and the results I get:

1) I have a enum defined as

public enum ActionState
{
NONE, INIT, LIST, ADD, EDIT, DELETE ...
}

2) I have a variable of this type in my action class:

ActionState state;

3) My jsp contains the following code (this is just an example):

state = 

true
false


4) Here are the results in the browser:
