Please recommend IDE for JSP and Beans

Hi guys,
I am looking for a decent IDE to work with JSP and Beans. I have tried JBuilder which has too much going on at the same time and I find it to be an overkill for what I am doing; I find NetBeans kind of irritating. I develop web applications, hence I dont need any GUI stuff for beans.
Just looking for something that will enable me to rapidly develop beans as a support system for JSP pages and at the same time, it should provide good support for coding JSP pages. Little bit of management functions wont hurt either, but are not required. I dont mind if I have to pay for the IDE. Any recommendations?

I like Eclipse for Java Development, and I use the MyEclipse plug-in for J2EE development.
There is a free J2EE plug-in (Lomboz) but I'd much rather pay the $29.99/year for MyEclipse. It's been perfect for me.

Good IDE for JSP/Servlets Development

Guys, I was looking for a good IDE for JSP/Sevlets development. I for myself wouldn't need or atleast wouldn't want to have one, but for our production they say they need one. So please can u guys advise one. I have downloaded and tried JDeveloper but it just hangs, dont know but looks like its too memory intensive. Any suggestions??? Thanks in advance

IBM's Websphere Studio Application Developer (WSAD) is a good one. It can also connect to any CVS servers, which allows you to control the versions. Hope this may help you...

How to set default encoding and charsets for jsp and servlets.

Hi,
Is there any possibility to set default encoding or charset for jsps and servlest (for both request and response)?
For example in Weblogic such parameters can be set in weblogic specific configuration files (weblogic.xml).
Thanks in advance.

Do you understand when a NullPointerException will be thrown? This will be thrown if you want to access an uninstantiated Object.
So look to the stacktrace and go to the line where the NPE is been thrown and doublecheck if the object reference is actually instantiated.
Or add a null-check to the object reference:if (someObject != null) {
    someObject.doSomething();
}or just instantiate it:if (someObject == null) {
    someObject = new SomeObject();
someObject.doSomething();

Memory leak with jsp and beans

The application we have created has one particular page that is designed to stay up in the browser and refresh with new information from database queries once every 60 seconds. Running with Tomcat3.2.1 and IE5.5
The problem is that the memory usage of java.exe continues to grow until the machine crashes from out of memory. It does take more than 24 hours to crash.
Things I have tried to do to track down the problem or eliminate the problem.
- I have explicitly set the scope of the beans to "page"
- I have watched the DatabaseAccess.class (the beans are all extended from this class) and put in code to watch how many instantiations of the class are made and subsequently garbage collected. This appears to be where the memory leak may reside - hundreds of instantiations from some other source than the page I am displaying.
- the top frame makes database queries for security and display of a menu system dependant upon security clearance. It does not set any time for refresh (refresh == 0). Nor does it explicitly set a scope for the beans.
- I have run a different jsp engine to see if this was directly related to Tomcat - same problem with resin2.0.0
The main jsp page that is in the bottom section of the page has the following code:
** only the relevant lines are included here
<%@ include file="../../common.jsp" %>
<%
refresh=60;
%>
<head>
<%@ include file="../../meta_head.jsp" %>
</head>
<body bgcolor="#FFFFFF" text="#003399" link="#660099" vlink="#990099" alink="#006666" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">
<%@ include file="../../access.jsp" %>
<%@ include file="../../page_title.jsp" %>
<jsp:useBean id="Line" class="jsp.Line" scope="page" />
<jsp:useBean id="Machine" class="jsp.Machine" scope="page"/>
<jsp:useBean id="Alarm_log" class="jsp.Alarm_log" scope="page"/>
contents of meta_head.jsp
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<META HTTP-EQUIV= "expires" content = "0">
<META HTTP-EQUIV="Pragma" CONTENT="no_cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache" forua="true">
<META NAME="robots" content="NOINDEX,NOFOLLOW">
<%
if (refresh > 0)
%>
<meta http-equiv="Refresh" content="<%= refresh %>">
<%
If anyone has some suggestions on how to trap this memory leak, it would be terrific. Or, some other things to try to stop the instantiation of the DatabaseAccess object (perhaps setting the scope of the beans in the header to "session" or "application"?).
Thanks in advance.
Roberta

jsp:useBean tags scope declaration :
page = Create a new instance on each load.
session = Load instance from the session, if not there, create one
application = Load instance from the ServletContext, if not there, create one.
Not sure how you are populating the data variables, but make sure you are closing all ResultSet, (Prepared)Statement, and Connection objects.

Help on JSP and Beans!

Hi! I am new to JSP and I need help on how to utilize java bean on JSP. I have gone through this forum, I found similar question but did not find any answer that could solve my question. Tons of thanks to anyone who could help me out!
I have a java bean class called Bean1, which I put under /ROOT/WEB-INF/classes/, and a JSP file that utilizes class Bean1, saved under /ROOT/, which should be a correct way indicated by several posts I found in this forum. But when I try to compile the JSP file over TOMCAT4.1 over http://localhost:8080/beanexample1.jsp, it throws me a lot of error messages (see below). I've been struggling for so long. Any help is greatly apprecitated! Thanks!

you need to put your bean in a package. do this by
making a sub directory under the classes directory,
let's say you call it "mybeans".
so copy Bean1.java to
/ROOT/WEB-INF/classes/Bean1.java
add the line "package mybeans;"
to the top of the Bean1.java file,
and then compile it there.
the standard way to use the bean in your jsp file is like this:
<jsp:useBean id="thisbean" scope="page" class="mybeans.Bean1" />
this <jsp:usebean> tag instantiates the bean for you.
then refer to it by its id:
thisbean.myMethod();
thisbean.setProperty();
I have a java bean class called Bean1, which I put
under /ROOT/WEB-INF/classes/, and a JSP file that
utilizes class Bean1, saved under /ROOT/, which should
be a correct way indicated by several posts I found in
this forum. But when I try to compile the JSP file
over TOMCAT4.1 over
http://localhost:8080/beanexample1.jsp, it throws me a
lot of error messages (see below). I've been
struggling for so long. Any help is greatly

IDE developing JSP And Hebrew Encoding

Hi.
I�m using Sun One Studio 4 CE.
I�m new Java Programmer.
I create JSP that use Taglib and read XML file written in Hebrew (Encoding iso-8859-1);
When I run the file on a Tomcat I have no problems.
But when I run the file within the ide of Sun One Studio I get gibberish.
So. Do you know where I cane change the character settings so It work the same?

The default encodings specified by the JSP and Servlet spec are unfortunately no good for most of the world!
There are two issues you need to understand: page encoding, vs response encoding.
Page encoding defines what encoding was used to create a particular page (JSP, XML, HTML). Unless the page encoding is set correctly, the entity that reads the page (e.g. the JSP parser, the web container, or the web server) cannot understand the characters before they do anything with them.
Response encoding defines what encoding is used when the server sends the HTTP response to the browser. This is actually a separate issue from page encoding. For example, a JSP could have the page encoding set correctly (so that the JSP parser can read it), but if the response encoding is not set correctly, then what goes to the browser is still gibberish.
To set the page encoding of a JSP, use a page directive:
<%@page pageEncoding="UTF-8"%>
(UTF-8 will work in Studio, there is no need to pick another more specialized charset).
In a HTML file or XML file, use an XML directive to set the page encoding. The XML directive will not work in JSP though.
So now the parser can translate the JSP into a servlet. But that's not good enough, because we also have to produce a response that the browser can understand.
To set the response encoding from a servlet, you can use
response.setContentType("text/html;UTF-8")
In J2EE 1.4, you can also use response.setCharacterEncoding("UTF-8");
To set it from a JSP, use
<%@page contentType="text/html;UTF-8"%>
All modern web browsers understand UTF-8, so that is a safe encoding to pick for the response. (It is a good encoding at the page level too if you use Studio. If you use another tool for your JSPs and it prefers a different encoding, use that at the page level but stick to UTF-8 for the response unless you have wireless clients and know that you need something else).
Note that this can only be set before any of the response is written. So if this JSP is included into another one, and the response buffer size has been exceeded, it won't work. So the response encoding must be set as early as possible.
What if you have a servlet that forwards to a JSP? Well, if you consider how the response object works, you should only have to set it once and earlier is better, so the servlet controller would be the obvious place. However, in J2EE 1.3, the encoding model wasn't well spec'd out, so on some servers, even if you set the response in the servlet, the JSP will overwrite it with the default if you didn't specify the content type. So experiment and set it in both the servlet and the JSP if you have to.
From J2EE 1.4, it's OK to set the response encoding once, it the servlet - the JSP container doesn't overwrite it anymore.

Where do I send great ideas for iPhone and iTouch applications??

I have some great ideas that Apple might be interested, but how do I let them know what they are. I don't want to ring as it would be an expensive international call!
If anybody working for Apple is moderating these forums could you please contact me and let me know what to do?
Or if any of you guys know how to speak to them, leave your comment.
My app ideas are fun and enjoyable, I'm sure you will be downloading them in the near future!

You can find an app developer and let them know.
I doubt Apple will accept unsolicited ideas, but you could use their feedback link if you feel compelled to do so.

JSP and beans

Is the bean spec for use w/ jsp any different than the one for J2EE? are there any required methods for use w/ jsp like in tag handlers?
Thanks

just make sure that you meet the basics of the bean properties for example
your bean class should meet the following constraints
no argument constructer
if you have instance variables i.e count
make sure that you have public getter and setters for it
getCount()
setCount(int c)
you may add as much methods as you want
make sure that your bean is existing either under web-inf/classes
or web-inf/lib

Where do I place JSP and Beans?

Hello,
I have just installed JDeveloper and have no idea where to place JSP pages and Bean class files so thet JDeveloper can access them when I run or debug a page.
Any help would be appreciated.

In JDeveloper, applications are grouped by one or more projects and a workspace containing projects. In your case, if you already have beans and JSPs built, here's what you need to do:
1. Create a new workspace.
2. Create a project using the 'create a project from existing source code' option.
3. Optionally check the 'copy to project's source directory' to include your files in the project.
Hope this helps,
Lynn

Character Encoding for JSPs and HTML forms

After having read loads of postings on character encoding problems I'm still puzzled about the following problem:
I have an instance (A) of WL 8.1 SP3 on a WinXP machine and another instance (B) of WL 8.1 without any SP on a Win2K machine. The underlying Windows locale is english(US) in both cases.
The same application deployed as a war file to these instances does not behave in the same way when it comes to displaying non-Latin1-characters like the Euro symbol: Whereas (A) shows and accepts these characters as request-parameters, (B) does not.
Since the war file is the same (weblogic.xml, jsps and everything), the reason for this must either be the service-pack-level or some other configuration setting I overlooked.
Any hints are appreciated!

Try this:
Prefrences -> Content -> Fonts & Color -> Advanced
At the bottom, choose your Encoding.

Load balancing for JSPs and servlets

Hi:
          I am using IIS as the proxy server, with the WLS plug-in, to a WLS
          cluster. This provides round robin load balancing just fine. Will it
          provide weight based load balancing if I set 'weblogic.system.weight'
          differently on each server, or is that not relevant for clustering JSPs
          and servlets?
          Sincerely,
          Ashish


Currently the plugins ( for NES, IIS and Apache) just use the round robin
          algorithm. the property
          weblogic.system.weight is used only be weblogic's replica aware clusterable
          RMI/EJB stubs.
          To use this property for your JSP/Servlet load balancing you have to use
          weblogic server as proxy fron-ending your weblogic cluster.

Please recommend IDE for JSP and Beans
