Java Mail Problems within JSP Page

Hi all,
I'm encountering the following problem. I hava a jsp file named common.jsp with holds all common functions like write header and footer and also a send mail function. i include this page in all my other jsp pages. In the signup page - i need to send out 2 emails, one to the administrator and the other to the user who signed up. so i call that send mail function twice. the first call works(meaning it sends out the email) but the second call gives me a No SMTP Provider exception. Can anyone help me with this.
thx a bunch
p.s: i have included the sendEmail Function below
public void sendEmail(String emailServer, String sEmail, String sName, String rEmail,
     String subject, String strmsg) throws Exception {
     java.util.Properties props = new java.util.Properties();
     props.put("mail.host", emailServer);
     javax.mail.Session mailConn = javax.mail.Session.getInstance(props, null);
     javax.mail.Message msg = new javax.mail.internet.MimeMessage(mailConn);
     javax.mail.Address sender = new javax.mail.internet.InternetAddress(sEmail, sName);
     javax.mail.Address receiver = new javax.mail.internet.InternetAddress(rEmail);
     msg.setContent(strmsg,"text/html");
     msg.setFrom(sender);
     msg.setRecipient(javax.mail.Message.RecipientType.TO, receiver);
     msg.setSubject(subject);
     javax.mail.Transport.send(msg);
}

This is what i use and it works just fine
import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
import javax.mail.*;
import javax.mail.internet.*;
public class sendMail {

     boolean debug = false;
     try{
Properties props = System.getProperties();
     Session session = Session.getDefaultInstance(props, null);
     Message msg = new MimeMessage(session);
     if (debug)
          session.setDebug(true);

     msg.setRecipients(Message.RecipientType.TO,
                         InternetAddress.parse(to, false));
     msg.setSubject(subject);
msg.setText(message);
     msg.setHeader("Mail","test.com");
     msg.setSentDate(new Date());

Problems with JSP pages and BC objects

Hi all. I have a new problem. I'm creating an application based on a database, using BC and JSP pages. I created entity objects from tables and then view objects. I put these view objects in an Application Module. When I test my view objects from This Application Module all works, but when I create a new JSP, I can't drag and drop any view objects in it. I'm using Jdev 10.1.2.
Is there any one who can help me?
Thank you,
Caterina.

I'm using the MVC pattern, so I have a Model directory that contains my BC, and a ViewController directory in which I want to create JSP pages with a Struts page flow.

EL problem in JSP page, boolean vs. String

We are migrating from WebSphere 6 to WebLogic 11g and are receiving the following error from the JSP pages where we use EL to determine if an element is readonly or not:
The method setReadonly(boolean) in the type BaseHandlerTag is not applicable for the arguments (String)
In doing some testing I can simplify the problem to this:
works (just using EL to set tab index)
jsp:
<c:set var="myTabIndex" value="765" />
<html:text property="user.email" size="28" tabindex="${myTabIndex}" readonly="true" />
source output:
<input type="text" name="user.email" size="28" tabindex="765" value="[email protected]" readonly="readonly">
doesn't work (added EL to set readonly attribute)
jsp:
<c:set var="myTabIndex" value="765" />
<c:set var="myReadOnly" value="true" />
<html:text property="user.email" size="28" tabindex="${myTabIndex}" readonly="${myReadOnly}" />
error output:
userProfile.jsp:60:86: The method setReadonly(boolean) in the type BaseHandlerTag is not applicable for the arguments (String)
<html:text property="user.email" size="28" tabindex="${myTabIndex}" readonly="${myReadOnly}" />
I'm not sure what is going on here and have spent two days researching this and trying different things to no avail. I don't believe any casting should be necessary. I thought for a while EL was not enabled but in my working sample EL is being used to determine tab index. The 'does not work' code works ok in WebSphere 6 and Tomcat 6, so it is just WebLogic we are having an issue with.
Thanks in advance for any help that can be provided.

Problems with JSP-Pages in more than 1 Frame

I have 4 Frames on my Page and every Frame is a JSP-Page. Every Page has different Data Tags, different View Objects etc.
I could run each of the 4 Pages without getting an error-message, but after starting the Frameset-Page, I get the Error-Message:
Error Message: JBO-27022: Failed to load value at index 1 with java object of type
java.lang.String due to java.sql.SQLException.
Now I press the Reload-Button of my Browser and it works !!!
Could anyone help me ?

Um, what am I missing? What is the work around? Is it impossible to use frames and data tag JSPs? Heino, how did you get around this problem?
Do I have to create separate App Modules for each frame (yuck)
Thanks!

This happens very frequently during development, I just do ctrl+F5 in IE to keep refreshing till I finally get a response back from the jsp or servlet... usually it takes about 2-4 refreshes to get the jsp to respond and after that its smooth till you change the jsp or restart Apache. Also this problem, in my experience, is associated with Apache forwarding requests to OSE via mod_ose and I dont see this problem if I access the jsp directly using the database listener http endpoint.
Hope this helps.

I have problem in jsp page

i have build jsp page using javascript and java for the database connectivity .....i have dbtest.java in which i write the sql quiry and set the sql column in setter and getter another java class.in dbtest.java i pass a date from jsp which restrict the sql query according to that date.this date when i write hard coded its works but when i pas i from jsp calender it not works.Now i want to print the Date value in dbtest.java to test whether the date is passed corect or not.How i can do once, If i want to print the date in XML how i can do it.Beacuase i have xml file to print the data return from the
dbtest.java???

First i would suggest to print the date which you are passing from jsp to java, in java class where you executing your query.
Second : For data not coming when passed the calender date, i would suggest to check the date format.

Plugin problem in JSP page with applet

i am using applets in my jsp page. the applet works properly if the java plugin is installed. it is not working with the default jvm.
my question is
if any client who does not have java plug in, views the page the plugin should be downlaoded automaticllly.
how do i get this happen.
Need support from Applet Gurus
Cheers!!!!!!!!!!!!!!

If you are using the <applet> tag, then it will not try to download the plugin. You should use the <object> and <embed> tags, which will only use the plugin, not the default JVM.
See the bottom of this page...
http://java.sun.com/products/plugin/1.3/docs/intranet.html
Only IE has a JVM built-in (and Netscape 4.x, if anyone still uses it). And in either case, that JVM is version Java 1.1.4, so it's very old.

Syntax problem in JSP page (PDKSTRUTS tag)

I have got a Struts project inside JDev 10.1.2.
Here is a part of my source code project:
<a href="procedure.do?event=DrillDown&procName=<c:out
value=${Row['Name'}"/>">click here
I am deploying this project inside Portal, so I am using PDK-STRUTS tag for
rewriting some specific tags (error, form, a, ...).
This part of source code must be replaced using LINK tag:
<pdkstruts:link action="procedure.do?event=DrillDown&procName=<c:out
value="${Row['Name']}"/>">click here</pdkstruts:link>
The following error message appears at compilation:
Error(31): Attribute: ${Row['Name']}"/ is not a valid attribute name
I think that this is a problem with the "dynamic" part of my link, generated by
<c:out value="${Row['Name']}"/> command.
I have also tried to following: (<c:out value=\"${Row['Name']}\"/>)
Compilation is ok but the <c:out> tag is not interpreted.
The question is : How can I translate this URL for preventing this error and
correctly interpretating the <c:out> tag ?

one thing i noticed from your codes, you missed the < ) > character.. try to look at your codes

Problem in jsp with container(JEUS)

Hi I am a developer in Korea
Nowadays I have a problem in jsp pages which have contained some pakage directive in a library path
so my problem is changing some of the classes in the package during service time.
Error result is
-Root Exception stack trace :
-jeus.servlet.jsp.compiler.JspCompileException: fail to compile : source = C:\TmaxSoft\JEUS6.0\webhome\epims_container1\_generated_\j2ee-modules\harweb\jeus_jspwork\_custermg\_html\_mypage\_600_MyReqJob_5fjsp.java, -error msg = C:\TmaxSoft\JEUS6.0\webhome\epims_container1\_generated_\j2ee-modules\harweb\jeus_jspwork\_custermg\_html\_mypage\_600_MyReqJob_5fjsp.java:76: cannot access custermg.MyPageQuery

-class file has wrong version 8241.8224, should be 49.0
-Please remove or make sure it appears in the correct subdirectory of the classpath.
- MyPageQuery myquery = null;
I don't know why this could be happed in random period of time It happens nearly each 10 hours . after this failure, the same error happen in other classes.
Before ten hours?.... No problem with the jsp pages
The number 8241.8224 tells me that it is not generated by java compiler but I don't have any clue but the above error
my run time environment is

so any help from you will be appreciated...

Mr. Ahmed,
Excuse-me by my bad english.
I experienced the same problem when surrounded my scripts with comment caracters:

If this is your case, simply uncomment it and the script will work fine.

After getting this kind of error I have analyzed my code furhter then I came to know that there was problem with static include tag.
In my jsp page I have used following line which is the main cause of error
<%@ include file="top.jsp" %>If I ommit this line then it is working properly.
Instead of static include I have used jsp:include also.
Still I m getting same problem.
We have to migrated from JDK 1.5 to 1.6 and Tomcat 5.0.28 to 6.0.14, still same problem is there.
We have tried a lot but didnt get success to overcome this problem.
If anybody having any solution then ur each reply will be appreciated.
Thanks in advance..........!!!!!!!

Hi "mshanu" and "amit" Thanks for ur replies Here I m posting the code of "top.jsp"........!!!!
<%@ page errorPage="errordisplay.jsp"%>
<table cellpadding="0"
       cellspacing="0" height=50 width=780>
       <tbody>
         <tr class="header">
           <td class="logo"><IMG SRC="assets/Logo.gif" BORDER=0 ALIGN=top></td>
           <td align="right"><span class="applicationtitle"><%@ include file="/contents/logo.htm" %></span><br>
           <span class="companyname"><%@ include file="/contents/companyname.htm" %></span></td>
         </tr>
        </tbody>
</table>To include top.jsp I have tried
<jsp:include page="top.jsp" flush="true">
</jsp:include>
         AND
<%@ include file="top.jsp"%>but none of this worked.
If I remove the include then It is working properly.
But I need inluded file too so that I am wondoring for the solution.
This problem seems very wiered to me. I dont know why it is happening.
This problem is started only when I used the TOMCAT 6.14.
Is it the bug of TOMCAT 6.14 or What somebody Plz help.
I got stuck here.........!!!!!!!!!!
It doesn't seem any problem with top.jsp. As per my thinking the problem is there in include due to that it doesn't compile the JSP page in Tomcat 6.0.
Earlier I am having same code running on the Tomcat 5.0.28 and JDK 1.5.0.
But problem occured when I have used Tomcat 6.x...!!

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )
