Using jsp:getProperty ... inside a scriptlet

When I use the following line in a jsp file,
<% boolean userExists=<jsp:getProperty name="xxx" property="exist/> %>
it gives an error saying that a term is missing, when I try to load this page. Any help is appreciated.
Thanks,
Nalini

Don't put the bean in the servlet context but use the HttpSession
session.setAttribute("xxx", loginBean);
in the JSP retrieve the bean by
<jsp:useBean id="xxx"
scope="session"
class="package.LoginBean" />
Where id = the name of the attribute in the session
class = the full package name of the bean.
Or
LoginBean myBean = (LoginBean) session.getAttribute("xxx");
Don't forget the import
<%@ page import="package.LoginBean" %>

No Sir,
I think I did not explained clearly.what I try to say is I dont want to use JSTL.I am using only Scriptlets only.I can able to receive the values from the database to the resultset.But I could not populate it in Combobox.
My code is :
<tr>
<td width="22%"><font color="#000000"><strong>Assign To Engineer</strong></font></td>
<td width="78%">
     <select NAME="Name" size="1">
<option><%=Username%></option>
</select> </td>
</tr>
in HTML
and in Scriptlets:
ps1 = con.prepareStatement
          ("SELECT Username FROM Users");
          rs2=ps1.executeQuery();
          System.out.println("SECOND Succesfully Executed");
          while(rs2.next())
               System.out.println("Coming inside rs2.next loop to process");
               Username=rs2.getString("Username");
               System.out.println("Success");
               System.out.println("The value retrieved from UsersTable Username is:"+Username);
In the server(Jboss console) I can able to display the username but I could not populate it in the Combobox .
Can you now suggest some changes in my code,Please..
Thanks a lot

Using JSP variable inside Java Script's alert function.

Hi Gurus,
We are trying to use alert function with one of the string variables populated inside JSP code, but its not working.
Here is the code snippet, please advice.
     <%
     oracle.apps.qot.util.RequestCtx.log("qotcustom.jsp",AOLMessageManager.getMessageSt(QotUtil.QOT_APPS_CODE, "XDPYY_DISC"));
     %>
     var alert_text="<%=AOLMessageManager.getMessageSt(QotUtil.QOT_APPS_CODE, "XDPYY_DISC")%>";
     alert(alert_text);
     Here in the first line we are using API to get text message defined in database, the line is getting executed properly and we could see output text message in debug log file, after this in the 4th line, we are assiging this string output of API to java script variable alert_text and further using alert function with the variable alert_text as argument. But alert function is failing, no errors are thown in debug log file.
Please advice whether we are doing any thing wrong.
Thanks in advance.

What pgeuens means is that you can't mix javascript and jsp/java code in this way.
ALL of the jsp/java code gets executed at the server end.
This produces an HTML page (with embedded javascript) which gets sent to the client.
The client then runs javascript code in response to events (onLoad, onClick, onChange etc etc)
So in this case, the jsp:forward will always be executed, because as far as the server is concerned, the javascript is just template text.
If you WANT to do a conditional forwarding on the server side you do it in java ie (horribly using scriptlet)
<%
if (testCondition){
%>
<jsp:forward>
%<
%>Or if you want to test what the client has entered client side, all you can do is submit the form, or navigate to a URL
<script>
function test()
if(document.f.htemp.value=="true")
alert("jus");
else
var s=document.f.htemp.value;
alert(s);
document.f1.action="success.jsp";
document.f.submit();
</script>You cannot run JSP code based on your javascript code.
Java. Javascript. Not the same thing.
Hope this helps,

Regarding jsp:getProperty

hi
i have a bean. I am setting the values of the bean and setting that bean as an attribute in the session.
In another jsp i am able to access the bean using
<jsp:getProperty name=".." property="..">
Here the name is the same as the attribute name.
But here i am not using <jsp:useBean /> tag.
I have read some where that <jsp:getProperty> or <jsp:setProperty> should be used with the <jsp:useBean> tag.
Please correct me where i am wrong?

I too read the same.
But i done an example on my local machine and i am able to access the <jsp:getProperty> without <jsp:useBean>
Consider Testbean.jsp

Is it possible to find and Replace a string inside a textfile using JSP?

FileInputStream fs = new FileInputStream("/opt/Abhishek/software/tomcat/webapps/AMS/listpass");
DataInputStream in1 = new DataInputStream(fs);
while (in1.available() !=0)
String str1=in1.readLine();
StringTokenizer st1 = new StringTokenizer(str1);
String node=st1.nextToken();
if (node.equals(sports))
String pass=st1.nextToken();
out.println ("<b>"+sports[i]+" <b>");
out.println("**Your Required Password**");
out.println(pass);
out.println("<br></br>");
%>
Hi ,
I have a text file (named listpass in the above code) inside tomcat-webapps folder containing a node name and its password.You could see the path of the text file at the starting line of the code.The Scene behind the program is once the particular node is clicked the password is retreived for the user against the particular node.What i would need is to change the password in the text file once it is retreived. So i would need to find the password that is retreived recently and change that one with a randomnly generated new password in the text file.
So can i do this?Is it possible to search for the string in the text file and replace that with a new one using JSP.For your note i am running all my HTML amd JSP inside the same folder where i have the text file in which the string has to be replaced .
Could anyone give your comments on this please?

Nasty in so many ways.
First off you shouldn't be doing stuff like this in a JSP. JSPs should just build HTML, use a Servlet and then pass data to a JSP for formatting.
Web applications are multi-threaded, so you have to consider what happens if several of these transactions come in at the same time, each trying to change the same data file.
It's not practical to amend text files in place, generally you have to create a new version of the file for each change because if the size of a password changes the subsequent bytes of the file would all need moving.
Use a database. Databases are designed to deal with these issues and there are perfectly good free ones around like Derby, MySQL and H2.

Problem using jsp:include from inside a custom tag

Hi, All !
          I have a problem using <jsp:include> from inside a custom tag. Exception is:
          "java.lang.ClassCastException: weblogic.servlet.jsp.BodyContentImpl"
          Apparently, weblogic tries to cast BodyContentImpl to JspWriterImpl and
          could not do this. Is it a bug, since in the 1.1 spec is said: "The
          BodyContent is a subclass of JspWriter that can be used to process body
          evaluations so they can retrieved later on."
          My code is:
          <wfmklist:items>
          <jsp:include page="item.jsp" flush="true"/>
          </wfmklist:items>


This is an area of contention with WL. It is not so tolerant with regards to
          the spec. I spent several days recently trying to convince it to accept the
          specification in regards to bodies and includes and it appears to have
          successfully rebuffed my efforts.
          Frankly, this is very disappointing. It appears that some shortcuts were
          taken on the way to JSP 1.1 support, and the result is a very hard-coded,
          inflexible implementation. As I have not seen the implementation myself, I
          hate to assume this, however one could posit that the term "interface" was a
          foreign concept during the implementation, other than as some annoying
          intermediary reference requiring an immediate cast to a specific Weblogic
          class, which in turn is apparently required to be final or have many final
          methods, as if being optimized for a JDK 1.02 JIT.
          I am sorry that I don't have any positive suggestions other than to use a
          URL object to come back in an execute the necessary "include" directly. You
          lose all context (other than session) and that can cause its own problems.
          However, you can generally get the URL approach to work, and you will
          hopefully avoid further frustration.

How to use jsp:scriptlet in site template

hi all,
I want to use <jsp:scriptlet> in site template, but jdev showed me an error msg when I put <jsp:scriptlet> in site template:
scriptlet can not work properly with OJSP, I checked the forums, one possible solution is to encapsulate java code in jsp taglib, but I dislike this solution.
Is there a way to disable OJSP? or any solution to use java code in site template?
Best regards

I believe the official word is if you are trying to use java code in a scriptlet in your site template then you are doing something wrong.
The goal is to keep java code separate from the template and pages. Any logic should go to your supporting serviece objects and all of your front-end work should be accomplished using available or custom tags.
Can you describe what you are trying to accomplish with this java code in your template?

Jsp:getProperty in tag attributes

Hii....
I have a custom tag that displays some information based on an attribute of the tag. I want to set information from a bean to the attribute using the jsp:getProperty tag...
I want to do something like.......
<mytagprefix:MyTag attribute1='<jsp:getProperty id="myID" property="name"/>' />
If I do it right now I am getting the string <jsp:getProperty id="myID" property="name"/> inside the my TAG.
any help will be appreciated.
sanjay.

I'm a bit rusty on custom tags, so maybe this isn't the best solution, but until you find a better one you can try '<%= myID.getName() %>' as the attribute.

Hi, Do you mean to say,
You have an HTML page in which you have a text field and an add button. If you enter anything in that text field and click on Add button the text field contents should be displayed in the same HTML page and you should be able to go on entering new values into the text field and you should be able to retain and display all the previously entered values..
and finally the list of added items are not stored in the database..
If this is the case
i. Your html form should be submitted to the same page.
ii. You need to have a Vector which holds the entered values.
iii. Bind the vector object to the request object and collect the same vector object from the request and display its contents...
I think this would help...

Export to Excel from Database using JSP

Its is an obvious thing...POI is known to need a lot of memory (the reason for that is most likely the OLE document format, which is quite complex).
I would have used something like the below to see if that can address my client's requirement.
public exportExcel(String fileName){
   Connection connection = null;
   Statement statement = null;
   ResultSet rs = null;
   PrintWriter out = null;
   int index=1;
   try{
     out = new PrintWrite(new FileWriter(fileName));
     connection = DbUtils.getConnection();
     statement = connection.createStatement();
     rs = statement.executeQuery("select * from Myschema.myfile");
     out.prinln("<table>");
     out.println("<th>COL1</th>");
     out.println("<th>COL2</th>");
     out.println("<th>COL3</th>");
     out.println("<th>COL4</th>");
     out.println("<th>COL5</th>");
     out.println("<th>COL6</th>");
     out.println("<th>COL7</th>");
     out.println("<th>COL8</th>");
     out.println("<th>COL9</th>");
    out.println("<th>COL30</th>");
     out.println("<thead>");
     out.println("<tbody>");
     while(rs.next()){
          out.println("<td>"+index+"</td>");

         if(connection != null)
           try{connection.close();}catch(Exception e){}
}and you can simply export the file using the method
ApplicationUtils.getInstance().exportExcel("c:/export/myapp/ApplicationTable.xls");If you are using Office 2000 and above you should able open it as an excel worksheet without any problems.
Hope that help :)

Uploading a file using jsp and com.oreilly.servlet lib package

Sorry to bother you but I need your help folks
I am developing an application to pick up files from a database and sent to a specified location on a different system.
I am presently trying to run this code,I have placed this lib package from oreilly which is supposed to encapsulate the usage of file uploads,which is a jar file called cos.jar into C:\Program Files\Java\jdk1.5.0_03\jre\lib\ext folder .I have a jsp page that calls the bean which does the upload and implement the classes in the oreilly package.I am using tomcat 5
[b]the jsp page that acts as the user interface
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Please Choose The File</title>
</head>
<body bgcolor="#ffffff">
<table border="0"><tr>
<form action="Upload.jsp" method="post"
enctype="multipart/form-data">
<td valign="top"><strong>Please choose your document:</strong><br></td>
<td> <input type="file" name="file1">
<br><br>
</td></tr>
<tr><td><input type="submit" value="Upload File"></td></tr>
</form>
</table>
</body>
</html>
this is the jsp page that calls the bean
<jsp:useBean id="uploader" class="com.UploadBean" />
<jsp:setProperty name="uploader" property="dir" value="<%=application.getInitParameter(\"save-dir\")%>" />
<jsp:setProperty name="uploader" property= "req" value="${pageContext.request}" />
<html>
<head><title>file uploads</title></head>
<body>
<h2>Here is information about the uploaded files</h2>
<jsp:getProperty name="uploader" property="uploadedFiles" />
</body>
</html>
[b]this is the bean class
package com;
import java.util.Enumeration;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.ServletRequest;
import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;
import javax.servlet.*;
public class UploadBean {
private String webTempPath;
private HttpServletRequest req;
private String dir;
// private ServletRequest request;
public UploadBean( ) {}
public void setDir(String dirName) {
if (dirName == null || dirName.equals(""))
throw new IllegalArgumentException("invalid value passed to " + getClass( ).getName( )+".setDir");
//webTempPath = dirName;
dir = dirName;
/* public String getDir()
return webTempPath;
public void setReq(ServletRequest request) {
if (request != null && request instanceof HttpServletRequest)
req = (HttpServletRequest) request;
} else {
throw new IllegalArgumentException("Invalid value passed to " + getClass( ).getName( )+".setReq");
public String getUploadedFiles( ) throws java.io.IOException{
//file limit size of 5 MB
MultipartRequest mpr = new MultipartRequest(req,dir,5 * 1024 * 1024,new DefaultFileRenamePolicy( ));
Enumeration enume = mpr.getFileNames( );
StringBuffer buff = new StringBuffer("");
for (int i = 1; enume.hasMoreElements( );i++){
buff.append("The name of uploaded file ").append(i).append(" is: ").append(mpr.getFilesystemName((String)enume.nextElement( ))).append("<br><br>");
}//for
//return the String
return buff.toString( );
} // getUploadedFiles
On running the code I find this error messages

Hi,
Looks like you are missing a file from the classpath. Make sure servlet.jar is available in your classpath. Ordinarily files in <tomcat_home>/lib directory should be added automatically. You need to check why it hasn't been added in your case. A good place to start would be the bat files in the bin directory viz startup.bat, catalina.bat etc.
cheers,

How to use jsp:plugin type="applet" in jsp

Hi ,
I have a JSP File.
How to use jsp:plugin tag in that.
When I specify the file name in code="applet.class" Then it is giving an error saying that It could not find the class.
What is the solution for this.

its not working.. it shows exception class not found exception.
i have placed the jsp and applet class in the same folder. but its not working.
jsp file path : OracleSpatial\mypackage\webmap.jsp
applet class : OracleSpatial\mypackage\demoApplet.class
demoApplet class inside package "mypackage".
code inside JSP is :
<jsp:plugin type="applet"
code="mypackage.demoApplet.class" width = "100%" height = "100%" >
</jsp:plugin>

Using jsp:getProperty ... inside a scriptlet
