How to debug JSP?

I'm a starter at JSP. I have JBuilder, websphere (both are trial edition), and J2EE installed on my computer.
How can I debug a JSP page?
Thanks

Well well, i say, i have not heard of any program you can use to debug your jsp. The only method i used is, placing numerous "System.out.println" before/in/after every loops, conditions and those statements that yields a result.

How to debug JSP in JDeveloper

I want to debug a JSP page in JDeveloper. I have put break point in jsp page, but when called from browser, control does not stop at break point in JSP. Please suggest, how to debug a JSP page in JDeveloper

You might use logging, log4j or standard jdk , <c:out> or even good old scriptlets <% ..%>and out.println(); to display the values of the variables that interest you.
Consult for instance chapter 14 of Beginning JSP, by Wrox, or any other equivalent.

How to debug jsp program

Thanks,
I havenot used Oracle before I know that
you could debug JSP in Visual Age for Java,
but where could we debug jsp code,
thanks,

You can debug JSPs and Servlets in JDeveloper locally in the IDE itself, or remotely.
To debug locally within JDeveloper, simply place breakpoints anywhere in the source code and choose Run | Debug from the main menu. The JSP is run using Oracle's Web-to-Go server.
Remote debugging requires a little more setup. See the online help for more information.

How to Debug JSP in Websphere 3.5 ?? Urgent

Hi,
can somebody help me debuuging JSP in Websphere Application server 3.5 .Remember I dont have
Websphere Studio or any other tool.any help in this regard is appreciated.
Thanks
Jack

In most cases, you can debug an application by using the old standby of printing status lines after each significant chunk of code. For example, you can always output the page's parameters to make sure you've received what you think you've received.
In the cases that Java throws an exception, you can make a rough guess as to what the problem is, based on the exception. A NumberFormatException usually occurs when you try to convert a letter into a number. The original intent would be to take a string "10" and convert that into the integer 10. SQL Exceptions are a little more vague, but again, you can at least narrow down the problem.
Specific debuggers, while nice to have, are not really necessary. Through experience, and trial and error, you will eventually discover (and remember) the most common kinds of errors and how to avoid them.
As a general rule, until you become proficient, always code a little chunk of the application at a time, and test that chunk to make sure it's working properly. It's far easier to track down a bug if you know it's somewhere in a dozen lines of code that you wrote that morning.
If you are using Internet Explorer, you may want to confirm that Explorer is not giving you "friendly error messages". You can check this in the tools->internet options->advanced dialog box. By default, IE hides specific error messages, including JSP errors, because Microsoft rightly feels that your grandmother would just get confused.

assuming you are running on Windows, you can use a .cmd file with the
 following command in it
 javac -g %*
 if you name it c:/java/bin/javac.cmd, then replace the line with
 compileCommand=C:/java/bin/javac.cmd,\

HOW TO: Debug a remote JSP

<h1>HOW TO: Debug a remote JSP</h1>
Note: The process of debugging a remote JSP on an Apache/Jserv
installation involves a couple extra steps that were not covered in the JDeveloper
3.2 documentation. 
Introduction
You use JDeveloper to debug JavaServer Pages (JSP) deployed and running on
a server that includes a JSP container, such as Apache Jserv. Your JSP container
will need to be configured to enable remote JSP debugging using JDeveloper.
JDeveloper allows you to use one of two protocols for JSP debugging - the
Oracle Java Virtual Machine (OJVM) debugging protocol or the Sun Java Platform
Debugging Architecture (JPDA). Before you start your remote debugging session,
you will have to choose which method to use. If you use the OJVM protocol, your
debugging session will run more quickly and you will have some additional features
to assist you. You can only use OJVM on a Windows NT system. If your server
is running UNIX or another operating system, you must use the
"classic" JVM.
Setting up your project for remote JSP debugging
Once you have created a JSP project, you need to set your project options
so that remote debugging is enabled: 
<ol>
From the Project menu, select Project
Properties. 
</li>
Click the Run/Debug tab.
</li>
From Debug Files As: dropdown list, select Remote
Debugging. 
</li>
Click OK. 
</li>
</ol>
Configuring the Remote Server
The following options must be changed on the host running the Apache/Jserv
server. These instructions assume the server is running Windows NT: 
Changes to jserv.properties
These options control which Java Virtual Machine is used and how it is loaded.

<ol>
For The Java Virtual Machine interpreter parameter <tt>wrapper.bin</tt>:

</li>
<ul>
[*]Comment out any existing entries by putting a <tt>#</tt> at the beginning
of the line.
<blockquote>
<pre>#wrapper.bin=C:\java1.1.8\bin\java.exe</pre>
</blockquote>
</li>
[*]Add a new entry with the full path of the <tt>java.exe</tt> that you want
to use. To use the JDeveloper 1.3 OJVM, put
<blockquote>
<pre>wrapper.bin=C:\Program Files\Oracle\JDeveloper 3.2\java1.2\bin\java.exe</pre>
</blockquote>
</li>
</ul>
For the Arguments passed to Java interpreter parameter <tt>wrapper.bin.parameters</tt>:
The value you put for this parameter depends on which Debugging Protocol
you will choose in the Remote Debugging Dialog in JDeveloper
when you start debugging.
</li>
<ul>
[*] If you want to use the JDeveloper 3.2 OJVM, put </li>
<blockquote>
<pre>wrapper.bin.parameters=-ferrari -XXdebugondemandquietport4000</pre>
</blockquote>
[*]If you want to use Java Platform Debugging Architecture, put
<blockquote>
<pre>wrapper.bin.parameters=-classic -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000 -Xdebug -Xnoagent -Djava.compiler=NONE</pre>
</blockquote>
The <tt>4000</tt> parameter defines the port number which the JDeveloper
debugger will use to communicate with the server. You can specify a different
port number, but it must match the port which you will enter in the Remote
Debugging Dialog in JDeveloper when you start debugging. 
</li>
</ul>
[*] For the PATH environment value passed to the JVM parameter <tt>wrapper.path</tt>
enter the location of <tt>jdwp.dll</tt>, which is part of the Java Platform
Debugging Architecture.
This parameter is only necessary if you will choose the Java Platform
Debugging Architecture debugging protocol:
<blockquote>
<pre>wrapper.path=C:\jpda\bin</pre>
</blockquote>
</li>
For the CLASSPATH environment value passed to the JVM parameter
<tt>wrapper.classpath</tt>: 
<ul>
Keep the location of <tt>ApacheJServ.jar</tt>. If it is not already
there, add it. 
<blockquote>
<pre>wrapper.classpath=C:\Program Files\Apache\JServ\ApacheJServ.jar</pre>
</blockquote>
</li>
Comment out the location of <tt>jsdk.jar</tt>. 
<blockquote>
<pre>#wrapper.classpath=C:\jsdk2.0\lib\jsdk.jar</pre>
</blockquote>
</li>
[*]Add the location of <tt>servlet.jar</tt> from JDeveloper 3.2.
<blockquote>
<pre>wrapper.classpath=C:\Program Files\Oracle\JDeveloper 3.2\lib\servlet.jar</pre>
</blockquote>
</li>
[*] Add the locations of <code>jdeveloper.zip</code> and <code>ojsp.jar</code>
from JDeveloper.
<blockquote>
<pre>
wrapper.classpath=C:\Program Files\Oracle\JDeveloper 3.2\lib\jdeveloper.zip
wrapper.classpath=C:\Program Files\Oracle\JDeveloper 3.2\lib\ojsp.jar
</pre>
</blockquote>
</ul>
</ol>
Changes to jserv.conf
<ol>
For the ApJServAction parameter: 
<ul>
[*] Comment out any existing <tt>ApJServAction .jsp</tt> entries by putting
a <tt>#</tt> at the beginning of the line. </li>
<blockquote>
<pre>
#ApJServAction .jsp /servlets/org.gjt.jsp.JSPServlet
</pre>
</blockquote>
[*]Add a new <tt>ApJServAction .jsp</tt> entry like this.
<blockquote>
<pre>
ApJServAction .jsp /servlets/oracle.jsp.JspServlet
</pre>
</blockquote>
</li>
</ul>
</li>
</ol>
Changes to zone.properties
<ol>
In the Servlet Init Parameters section: 
</li>
<ul>
Add the following lines. 
<pre>
servlet.oracle.jsp.JspServlet.initArgs=emit_debuginfo=true
servlet.oracle.jsp.JspServlet.initArgs=jspcompiler=oracle.jdeveloper.jsp.JspOjcCompiler
servlet.oracle.jsp.JspServlet.initArgs=classpath=C:\Program Files\Oracle\JDeveloper 3.2\java1.3\jre\lib\rt.jar
</pre>
</li>
</ul>
</ol>
Copying the JSP to the Apache/Jserv Server
Once you have restarted the server with the modified parameters, you need to
copy your JSP to the server's HTML root directory. For most Apache installations
this is <tt>C:\Program Files\Apache\htdocs</tt>. 
You also need to make sure the JSP is in your HTML directory in the JDeveloper
tree, typically <tt>C:\Program Files\Oracle\JDeveloper 3.2\myHTML</tt>. The
reason for this is JDeveloper uses the folder name as its package name.
Debugging a JSP
Debugging a JSP is very similar to debugging any other Java program.
<ol>
From the Run menu, select Debug
"filename.jsp". 
Start the JSP running (for example, start your web browser and open a
connection to the JSP). 
Debug as normal. 
</ol>
If you are using the JDeveloper OJVM debugging protocol, you will be able
to disconnect from the JSP container. This allows you to stop debugging, but
leave the JSP container running. In addition, you will be able to use two extra
debugging functions that are not available using the JDPA protocol - Run
to End of Method and Set Next Statement.
If you using JPDA, you must use Stop to end your debugging.
Using this method will also stop the JSP container.

Hi,
It again same as you do in your local server...You can monitor the BPEL process flow in the em console and debug..if its not sufficient....u can also monitor the logs located at
<SOA_Home>\user_projects\domains\domain1\servers\soa_server1\logs to debug.

I modified some javabean, complie them and put classes override the old classes,
but the web app can not find the new classes.
Any one know How to debug web app(with javabeans) in weblogic?
thanks!

how to config the hot deploy?
thxSorry, for this delay in responding. I had set notify me with email option in Watch This topic; but I never did get any email notification.
I use wls6.1; I think the process may be very similar to this in wls8.x. In wls6.1 (sp5), this is done via the -
Dweblogic.ProductionModeEnabled=False or
Dweblogic.ProductionModeEnabled=True
in the startup cmd/sh script. Out of the box, wls6.1 is set to Dweblogic.ProductionModeEnabled=False which automatically enables hot deploys.

How to debug when you can't recreate error consistently

I have a simple illustrator-type application in which I draw rounded rectangles to a JPanel and then the user is able to move them around (the position and repaint is done in via the mouseDragged interface.
Sometimes, the application shuts down when I am dragging a box with this message:
# An unexpected error has been detected by HotSpot Virtual Machine:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d236a0c, pid=3400, tid=2716
# Java VM: Java HotSpot(TM) Client VM (1.5.0_07-b03 mixed mode, sharing)
# Problematic frame:
# C [dcpr.dll+0x6a0c]
# An error report file with more information is saved as hs_err_pid3400.log
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
I checked the error report and it suggests the problem is within the PathFiller.WriteAlpha. The entire report is below. The problem I have is that if I restart the application and place boxes in the exact same locations as before, and try moving the one that caused the error, the error is not thrown.
I have no idea how to debug this as I can't even consistently reproduce. I just upgraded to the newest JDK (I think it was 7).
Thanks for any insight and help you can offer.

This is not your bug, it's Sun's. All you can do is to:
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
On the other hand, if you cannot afford to wait and just
want to find a quick workaround, you will at least need
to find a way to reproduce the bug with a reasonable
frequency. If you are absolutely unable to reproduce it,
just forget it, but still report it to Sun.

How to debug adapter module in PI 7.1

Hello all,
I am trying to figure out how to debug adapter module in PI 7.1.
I guess runtime debugging ( switch AS java in debug mode and attach NWDS to the AS Java to debug as module is being executed) is not possible with adapter module. Please let me know if this is indeed possible and how to enable it.
The only option is to send debug information to log file. So in the module code like:
audit.addAuditLogEntry(key, status, message);
location.debugT(SIGNATURE, message);
I've read that for PI 7.0, you need to add log-configuration.xml to meta-inf. Is this still required for PI 7.1?
My next question is how to read the log in audit log and in location. I've read that the audit log can be read in .../MessagingSystem/monitor/monitor.jsp, under which section of the page I can read the audit log? I can't see any of my log there.
For log in location, I guess I need to go to NWA, can you please share the path (navigation) in NWA to see the location?
Thanks
Jayson

It is possible for adapter modules as well. I know this from our developers
It should work like this:

In the RWB under Message Monitoring for Adapter, or try the shortcut

2.How to debug my application in Eclipse Europa by putting break points.
3.how should i add Tomcat6.0 to my project in order to debug my application so that i can put break points while running the applications and observe the values.
Thanks
Bala

You may find this tutorial useful regarding to JSF, Eclipse and Tomcat: http://balusc.blogspot.com/2008/01/jsf-tutorial-with-eclipse-and-tomcat.html
To put breakpoints, just doubleclick on the left gray rule of the code, you'll get blue bullets at the left rule, indicating a break point. Run Tomcat in debug modus (rightclick Tomcat � debug). Use the Eclipse debug perspective to step in the code (window � open perspective � debug).

Can I debug jsp in eclipse ?

I am using wtp eclipse and I want to debug jsp please guide me how to ?

Yes, just the same way as you do with normal Java classes. Run the server in debug modus and put breakpoints in the source file.
But do you have business logic (scriptlets?) in your JSP then? I'd to put them in separate Java classes (Servlet, Bean, DAO, Utility, etc). It will greatly ease unit testing and debugging (and also maintenance!).
