Struts tomcat

hy!
my promblem doesn't exactly match JSP and JSTL, but my problem is in the beginning.
i've installed NetBeans IDE 3.6 on my laptop, this includes tomcat.
then i installed a separate tomcat server...i downloaded struts, searched for instructions how to start an example (included in the struts download archive) and followed instructions...first with the separate tomcat. the message i got when i entered the url was:
"the connection was refused when attempting to contact localhost:8080"
i restarted tomcat, but nothing happend...
then i tried to include it to a netBeans project, but then several errors occured...
i don't know what i'm doing wrong!
my jdk version is "sdk1.4.2_04", classpath is set
please give me help either to include struts to netBeans or to solve my problem with the separate tomcat...
i'm open for all...
i hope i could explain my problem in an understanding way

Hi Baer,
do you get any errors when you start up tomcat? Have you tried going through a command prompt window and starting tomcat? What is the output?
If you go to your <tomcat>/bin directory and run: catalina start you should see what the output of tomcat is. Also, is tomcat already started as a service? If so, you might want to disable that service.
Best of luck,
Nate

Content-type problems while using struts+tomcat+apache+mod_jk

Hi!
Could anyone tell me how to solve the following problem.
Struts-application works under apache + mod_jk + tomcat 3.3.1. Operating system is Linux.
It's impossible to me to make tomcat to send HTTP-answers in UTF-8.
I was trying the following:
1. Set <DecodeInterceptor defaultEncoding="UTF-8" /> in server.xml
(Has no effect. Tomcat responds with Content-Type: text/html; charset=iso-8859-1)
2. Insert <%@ page contentType="text/html; charset=utf-8"%> into each page header.
(Works fine but when struts-application gets GET/POST-data the two-bytes national characters
are comverted into "?"-symbols)
Is there any way to make tomcat 3.3.1 to send HTTP-answers in UTF-8?

I don't know what the DecodeInterceptor does... but....
If you use number 2, you are only telling the browser what that page's output is. When you process the data, Tomcat for some reason always reads it as ISO8895-1, so you need to tell Tomcat to change it to UTF-8. You can do that by calling request.setCharacterEncoding("UTF-8"), either in the JSP page, or if you need it in a servlet, you can do that in a filter...
It's somewhat described here how to set it up...

Remote debug struts Tomcat 4.1

I'm trying to setup jdeveloper 10g to remote debug a struts application which is located in the web apps of the tomcat directory. I called myself setting up everything by using the help documentation. I'm doing something wrong, I need some help.

Hi.
For remote debugging, the Virtual Machine setting on the Runner options panel is not used. That Virtual Machine setting is used for local running/debugging, when JDev will be launching the debuggee process.
For remote debugging, you need to select the correct Remote Debugging Protocol. In the most recent JDev (the preview that came out in November/December 2004), that setting is in the Tools Preferences dialog box, on the Debugger - Remote panel. In previous versions of JDev, that setting is in the Project Properties dialog, on the Debugger - Remote panel (it's right under the Remote Debugging checkbox).
If you will be starting up Tomcat with ojvm (with -XXdebug,detached,port8080 option), then you want to select the "Attach to OJVM" radio button.
If you will be starting up Tomcat with Hotspot (with -Xdebug -Xrunjdwp:<blah blah blah> options), then you want to select the "Attach to JPDA" (or perhaps, but less likely, the "Listen for JPDA") radio button.

What is a listener for/ especially in struts + tomcat + hibernate

some example code sugguested that we should create a listener for the hibernate connection. i stil dont get it. anyone can explain this?

The listener is the product that allows APEX to communicate with the App Server.. The supported App servers are WebLogic & GlassFish (for version 2.x of the listner, version 1.x allows the usage of Tomcat and OC4J)..
In the prior database/app server setup you would use the HTTP server (Apache) with a mod called Mod_plsql to communicate between the app server and the database.
With the APEX Listener 2.x you can use it to host RESTful web-services and allow your APEX apps to import Excel workbooks directly and also print PDF files similar to FOP.
You really Can't share session state with other apps.. Why exactly would you want to do this??
Re: Run java applets in APEX, No you can run them in the app server.. Apex can work with Oracle EBS, there is a posted whitepaper on this from Oracle:

Handling runtime Exceptions in tomcat / struts

Hi, I'm trying to find a way to cleanly handle exceptions in struts/tomcat. I've read a number of suggestions in my struts book, but none seem to work.
What I've done is created an instance within my action class that deliberatley creates a NullPointerException. I want to be able to display an errorPage at this point, but whatever I do I just get the same horrible HTTP Status 500 error.
Can anyone give any advice with this please?

Check out the org.apache.struts.action.ExceptionHandler class. Basically you extend this class, and override the execute method. In the struts config file you add this entry...
<global-exceptions>
<exception
handler="the pathname of the class that extends ExceptionHandler"
key="message properties entry"
path="error page jsp"
scope="request"
type="type of Exception you want to catch (Throwable)"/>
</global-exceptions>
This basically acts as a "catch all" global exception handle.

There should be a ApplicationResources.properties in your
/WEB-INF/classes
This file should also be in your servlet mapping for struts in the web.xml.
In the ApplicationResources.properties should be a key that is called in the jsp you are using.
For
<bean:message key="index.title" />
something like:
index.title=Welcome!

UIX/Struts+BC4J Comparision

In one project, I'll develope a Thin-client Web-based appliation, this is my hypo architecture:
1. JSP+Struts+Tomcat+Oracle 9i
2. JSP+UIX+BC4J+Tomcat+Oracle 9i,
I'm a newbie to Oracle UIX, can anybody give me suggestion about the comparision between Struts and UIX ?
or How about the second architecture?
Welcome any comment/advice.
Thanks in advance.

Jaas tomcat auto login

I have a webapp running Struts, Tomcat 5 and JAAS. After a user
registers on my site they then verify their e-mail through clicking a
link. How can I get them to be automatically logged in after clicking
that link using JAAS??

Did you find how to make automated login.
I'm trying to do almost the same thing.
I want the same identity for each user in order to be able to communicate with another web app running on the same server.
Some kind of impersonation will be a good solution too.
I have no solution which I can deploy on a live server yet.
You are well dressed

Problems with JAVA_HOME

Hope someone can help me with this quickly. I've been setting up various software for my job (Ant, Struts, Tomcat, etc) and I'm having trouble with environment variables. And in case it matters, I'm using Vista.
I don't have any problems when I put the absolute paths in the PATH variable, but it's when I try to use JAVA_HOME, ANT_HOME, etc. that the weirdness begins. Here's my command prompt:
C:\Users>echo %ANT_HOME%
C:\dev\ant
C:\Users>echo %path%
C:\Windows\system32; C:\Windows; C:\Windows\System32\Wbem; C:\dev\java\jdk\bin; C:\dev\ant\bin
C:\Users>ant -version
'ant' is not recognized as an internal or external command, operable program or batch file
C:\Users>cd C:\dev\ant\bin
C:\dev\ant\bin>ant -version
Apache Ant version 1.7.0 compiled on December 13 2006
So when I set the current directory to my ant directory, it detects it, but the path seems to be exactly the same and doesn't work.
This did work once before. But then I restarted my computer, and it suddenly couldn't detect java or ant anymore.
Hope that makes sense, is there something I'm just not seeing? Thanks.

Ha nevermind, solved it. The fact that adding a space between elements in the path screws it all up completely went over my head last night.

Session problems due to abruptly closed browser window

Hi
We have an application running which uses JSP,struts , tomcat and JMS. When the user logs in we store some values in the session which are very critical for the application to function. we have kept a logout button thru out the application. After pressing the logout button those values are cleared from the data structure we maintain at the application scope. But if the user closes the browser window then those "clearing" operations dont take place which causes critical problems.
can anybody suggest anything on this situation ?
Martin

Yes, have a session timeout value set and write a SessionListener that cleans out the cache whenever a session is invalidated.

Is JDeveloper ready for me?

Hi,
I've heard good things about JDeveloper so I have been giving it a spin recently. The learning curve is steep (i come from Eclipse).
My new project is about to start and I wanted to know if you think it is good enough to use as the main IDE. I found the JSF functionality good (but a bit slow), I've seen bugs reported with the PL/SQL debugger (NOT good) and random errors reported when using the table designer.
Perhaps I should go back to Eclipse for this project and wait a couple more months for JDeveloper to stabilise?
What do you think?
Rakesh

hi Rakesh ;
For me , jDev is very stable using ADF uix and ADF bc4j.
Some months ago, i though that jDev was just another java IDE and the best of choice about using it or not was related to ADF choosing ADF or NOT;
But i was quite wrong, jDev certainly one of the best tools to java developing, just to see the helper utilities it has relating debugging and coding, and we expect more for new version incoming as we could see downloading it's preview version;
About the learning curve , i can't say nothing because , i came from delphi and never work with java until i choose jDev, so i spend a looooonnggg time to learn all the ways for java. Certainly it was more about java (and it's word, j2ee, struts, tomcat, jdbc and more was just short names for me) than about jDev;

XML or Sql or ??

Hi
I'm developing my first app for iOS using Flashbuilder 4.6 and need to have a database to keep track of certain items, probably no more than 20 items per record (including username and password) in a single table for a single user.
I don't want to use server technology but want to keep the data on the device. My question is should I use XML or SQL or some other way to store the data on the device.
Any guidance would be appreciated.
Thanks.

Ok ... drop sitemesh and jmeter. So we have:
mysql + hibernate + log4j + ant + struts + tomcat (app server) + apache (web server) running on freebsd and tested using junit.
mysql - Half decent and free. Easy to setup.
hibernate - Provides OR mapping. Takes a bit of learning but keep it simple and you'll be ok.
log4j - Really easy to setup and use.
ant - Again will take a bit of learning but once you get going you can write a basic ant script in no time (it integrates really well with eclipse)
struts - Probably the most difficult technology to learn but it will keep your app well structured. (MVC)
tomcat + apache - You can probably get away with just tomcat but if you've got time use the jk2 connector stuff.
freebsd - Any unix based OS will do really.
junit - Will look really good if you show you've properly unit tested your work. And you can integrate with junit with ant.
How long have you got to do this btw ...

Blob.getBinaryStream not work !

Hello all,
The blob length give me correct number (~7445), but the inputStream image always return 0. I stuck here. I use oracle10g. Please help,
Thanks,
pstmt = conn.prepareStatement("SELECT aggraph FROM antigenic_t WHERE agid = ?")
pstmt.setString(1, refid);
rset = pstmt.executeQuery();
if(rset.next()){
Blob blob = rset.getBlob(1);
log.info("BLOB length @@@@ ---> :" + blob.length());
image = blob.getBinaryStream(1);
// image = ((oracle.sql.BLOB)blob).getBinaryStream(1);
log.info("inputStream length @@@@ ---> :" + (int)image.available());
}

Hi there,
Here are my code, hope it help; I use struts, tomcat and jsp. These are the key code, but you need to put the right place :)
For insert:
InputStream image = isyourfilereadInputStream...
pstmt = conn.prepareStatement("INSERT INTO antigenic_t ("agid, aggraph) VALUES (?, ?)");
pstmt.setString(1, agid);
oracle.sql.BLOB newBlob = oracle.sql.BLOB.createTemporary(conn, false, oracle.sql.BLOB.DURATION_CALL);
byte[] imageBytes = null;
imageBytes = new byte[(int)image.available()];
int bytenum = image.read(imageBytes);
newBlob.putBytes(1, imageBytes);
pstmt.setBlob(2,newBlob);
int rowcnt = pstmt.executeUpdate();
for get image from oracle:
InputStream image = null;
pstmt = conn.prepareStatement("SELECT aggraph FROM antigenic_t WHERE agid = ?");
pstmt.setString(1, refid);
rset = pstmt.executeQuery();
if(rset.next()){
Blob blob = rset.getBlob(1);
image = blob.getBinaryStream();
byte by[] = new byte[1000000];
int index = image.read(by,0,1000000);
response.setContentType("image/tif");
out = response.getOutputStream();
while(index != -1){
out.write(by,0,index);
index = image.read(by,0,1000000);
}
