Instantiating/declaring classes in JSP (Was: simple question)

I know this is somewhat off topic, but I have looked everywhere and can't
find the answer to this simple question...
Is there a way to test and see whether a variable has been instantiated and
if it hasn't, instantiate it?
Object myObject;
if (myObject == null) {
myObject = new Object();
}
Tada!
My problem is that I am working on an application that makes use of jsp's
that are included inside many others. I want to use a bean, but if I call
it by a different name in every spot, then they don't share information. If
I use the same name, and the containing jsp has already declared that it is
using the bean, then it gives me an error and says it has already been
declared. Any ideas on how I can get around this? Thank you in advance for
any help!!!
Ah! A different question...
Try jsp:usebean... If the bean is declared, it'll use it. If not, it'll
instantiate a new one.
If you want to know whether you've instantiated it, or if you are reusing a
previously instatiated class, it's a bit more difficult. The only way I can
think of is by setting a variable internally on instantiation and checking
that. Of course, you'd have to ensure that all the developers do the same
thing.

tomcat.policy limitation?
I am trying to grant a servlet in the
/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/WEB-INF/classes/joe/
directory write permissions to the /test.txt file.
//---
The following code snippet from my tomcat.policy file seems to work
correctly;
I can write to the /test.txt file just fine with my servlet.
grant codeBase file:/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/- {
permission java.io.FilePermission /test.txt, write;
};
//---
BUT, the following code snippet does NOT work correctly.
grant codeBase
file:/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/WEB-INF/- {
permission java.io.FilePermission /test.txt, write;
};
I get the following error message :-((
Error: 500
Location: /servlet/joe.joe1
Internal Servlet Error:
java.security.AccessControlException: access denied
(java.io.FilePermission /test.txt write)

...
etc.
//---
What the heck?!?!
Anyone have any ideas for me to try?
I want to create a bunch of user/programmer subdirectories like
/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/WEB-INF/classes/joe/
/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/WEB-INF/classes/tom/
/usr/tomcat/jakarta-tomcat-3.2.2/webapps/ROOT/WEB-INF/classes/henry/
etc.
so that I can grant all servlets in these directories and subdirectories
read/write access to their own separate directory structure so they
won't be able to write over anyone elses files, including the system
files, of course.
This is a wierd one.
Thanks for any help!

Re: Too many process?
Hi, Are you using native threads? if so then this is ok (from memory each java thread gets mapped to a seperate process). If you use green threads then they should share a single process (from memory).

All, Thanks for the suggestions. I found my problem. Here is a short synopsis in case anyone else runs into this. Assuming the problem was security related, I moved my servlet into it's own context and added rules to tomcat.policy for the permissions I needed.

It seems that the problem gets better for a while, which makes you think that something you did fixed it, when in reality, it is just lying dormant like some gestating alien life form waiting for the right point in development where it can burst forth again. Sometimes, restarting Tomcat and Apache helps. Sometimes I reboot the whole machine, and other times, even that does not work. Then, I just have to wait until it decides to play nice again. It is always the .jsp pages that don't load, though. The frame containing the .html page loads fine, and that has a link to another .html page which also loads fine when clicked. Val
User Authentication Apache+mod_ssl+Tomcat 3.2.3
Hello all, I am using the above config and have a JDBC realm set-up using FORM based login. What I want to know is: 1. Is it possible to get the login page to use SSL (https or 443 port) and once the user is validated continue on the standard (http 80 port)? 2. If so, is there any documentation with regards to this?

IIS 5.0 and Tomcat not connecting
Hello, I've set up tomcat and IIS 5.0 on my machine (win2k server). Tomcat works fine if I call it wiht the :8080 extension. Likewise, IIS servers normal pages fine. The problem arises when I try to get them to work together:) I've followed the howto exactly, and double checked every step, install and troubleshooting, a couple times. All my spelling is correct, and all the files are in the right places. The error I get when I try to get http://localhost/examples/jsp/ is: 2001-07-20 14:19:27 127.0.0.1 IMPSERVER\Administrator 127.0.0.1 80 GET /jakarta/isapi_redirect.dll+ - 404 Mozilla/4.0+(compatible;+MSIE+5.5;+Windows+NT+5.0) Anyone have any ideas? I've been searching the mailing list archives for a while, and the internet, and not having any luck... thanks! Dave

Here is the second option... -Original Message- From: Forrest R. Girouard [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 18, 2001 3:18 PM To: [EMAIL PROTECTED] Subject: Re: Tomcat Frames I could be wrong but I thought that if the server supports HTTP 1.1 and the client does not receive a 'connection: close' with the response that it will re-use the connection. This means that some of the multiple simultaneous requests might be handled by the same connection and if the server has a bug in it's handling of persistent connections one might get an unexpected connection reset by peer. So, if all the other possibilities can be eliminated I would investigate the handling of persistent connections. Cheers, Forrest Craig R. McClanahan wrote: Servers don't know anything about frames. The only relevance it has in this context is the fact that your browser will typically do multiple requests (one per frame) simultaneously, up to some maximum -- typically 4. This is the same reason you see multiple images being downloaded simultaneously (these are also done on separate requests). In most browsers, the number of simultaneous requests is configurable somewhere. The server is reporting connection reset by peer in the middle of a request. That means one of the following things: * The browser started a request and the user pressed STOP. * The browser started an request in one frame and JavaScript on another frame told it to go somewhere else (which has the same effect as a user pressing STOP). * You have a meta refresh reload someplace that is firing so fast that the previous request hasn't had a chance to complete yet. The five second periodicity makes me pretty suspicious of this. * You have some network component in between (a router or proxy) that is misbehaving. * You have some completely separate connection attempts going on that are disobeying the HTTP protocol (such as doing a telnet connection to port 8080 and then disconnecting).

Any pointers on where to look would be greatly appreciated.

Re: starting tomcat 3.2.3
Hi Sampath, This is most likely one of two things: 1) Some other program is already running and using port 8080. You can use netstat to check this out. You might to telnet to port 8080 and see what you get. 2) This may be because you had previously started Tomcat, without stopping it, and are now trying to start it again. You should stop tomcat using the shutdown scripts, or, easier -- use the tomcat.sh script (type 'tomcat.sh' to see usage) to start and shutdown Tomcat.

RE: starting tomcat 3.2.3
This usually happens when tomcat's default port (8080) is already in use. A simple check would be to point your browser to http://localhost:8080; and see if you have another http service running on that port. If not, it could be that some other service is using that port.

Getting the values of context-params defined in web.xml ??
I set up a servlet web.xml based on the sample web.xml provided with
the Tomcat 3.2.2 distribution. I left in the example definition of the
context-param ( shown below ). I added code (shown below) to the
servlet to print the names of all context-params. I didn't see any of
the context-params I added to my web.xml and I didn't see the example
either. I should point out that defining init-params on a per servlet
basis worked as described and is my current work-around.
Adding to the confusion is the example in the Tomcat 3.2.2 web.xml.
The example says:
The values actually assigned to these (context-param) parameters can
be retrieved in a servlet or JSP page by calling:
String value = getServletContext().getInitParameter(name);
However, the javax.servlet.ServletContext interface does not have
getInitParam( String ) method. And, to add to the confusion, there IS a
getInitParam ( String) method in the javax.servlet.ServletConfig
interface.
Since this sort of thing is done all of the time I'm sure I'm just
missing something really simple but after several hours of trying
everything I can think of I still can't get those damned
context-params. Can anyone shed some light on this situation?
.
Thanks in advance,
--beeky
Typical context-param definition in web.xml from Tomcat:
web-app
context-param
param-namewebmaster/param-name
param-value[EMAIL PROTECTED]/param-value
/context-param
!-- all other web.xml contents omitted --
/web-app
Servlet code to print context-param names:
Enumeration contextParams =
getServletConfig().getInitParameterNames() ;
while ( contextParams.hasMoreElements()) {
String p = (String)contextParams.nextElement() ;
System.out.println( config param= + p);
}
I also tried:

String p = (String)contextParams.nextElement() ;

request.getAttribute() problems
Hi all, I have a Bean whose scope I would like to set to request. I would like to retrieve this Bean's instance when the next page is requested. On the first page, I have: jsp:useBean id=beanclass class=BeanClass scope=request / On the next page, I have: BeanClass b = (BeanClass) request.getAttribute(beanclass); However, when I try to use instance b of my Bean, I get a NullPointerException. The strange thing is that the code seemed to working in Orion. Is there something I'm doing wrong? Note that I can use the instance without errors when I set the scope to session and use session.getAttribute() instead but I don't want to do this as my instance should only last for a request.

Re: Getting the values of context-params defined in web.xml ??

Subject: Getting the values of context-params defined in web.xml ??
I set up a servlet web.xml based on the sample web.xml provided with
the Tomcat 3.2.2 distribution. I left in the example definition of the
context-param ( shown below ). I added code (shown below) to the
servlet to print the names of all context-params. I didn't see any of
the context-params I added to my web.xml and I didn't see the example
either. I should point out that defining init-params on a per servlet
basis worked as described and is my current work-around.
Adding to the confusion is the example in the Tomcat 3.2.2 web.xml.
The example says:
The values actually assigned to these (context-param) parameters can
be retrieved in a servlet or JSP page by calling:
String value = getServletContext().getInitParameter(name);
However, the javax.servlet.ServletContext interface does not have
getInitParam( String ) method. And, to add to the confusion, there IS a
getInitParam ( String) method in the javax.servlet.ServletConfig
interface.
Since this sort of thing is done all of the time I'm sure I'm just
missing something really simple but after several hours of trying
everything I can think of I still can't get those damned
context-params. Can anyone shed some light on this situation?
.
Thanks in advance,

Typical context-param definition in web.xml from Tomcat:

param-namewebmaster/param-name

Servlet code to print context-param names:
Enumeration contextParams =
getServletConfig().getInitParameterNames() ;
while ( contextParams.hasMoreElements()) {
String p = (String)contextParams.nextElement() ;
System.out.println( config param= + p);

I also tried:

Performing actions prior to j_security_check
Hello, I have a single user system and I set up a JDBCRealm where the form-login-page is a servlet which either redirects to a simple login page or to a registration page if this is the first use. The simple login page works fine. However, on the registration page, I want to store the registration information as well as inserting the username/password into the jdbc table. If everything is successful, I want to redirect again to j_security_check (using the parameters j_username and j_password) from the registration page. I was hoping that authentication would succeed at this point and the user would be redirected to their original page, since I just added the user to the database. Unfortunately, I get the following traceback instead: java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:380) at org.apache.tomcat.session.StandardSession.setAttribute(StandardSession.java:731) at org.apache.tomcat.request.FormSecurityCheckHandler.doService(AccessInterceptor.java:540) at org.apache.tomcat.core.Handler.service(Handler.java:287) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:812) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:758) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java:213) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:501) at java.lang.Thread.run(Thread.java:484) Anyone have any idea what I'm doing wrong or a better way that I should be doing this.

IE and tomcat
hello, I am having a little bit of problem which is very annoying, so may be somebody here can help me. My servlet processes flash template files (.swt) and genarates flash files (.swf). It handles all files from any directory with extension .swt (for those who is interested it's an open source project: http://www.flashgap.com). It works fine when a client is netscape, I mean when I type something like http://myhost/card.swt the servlet receives one request and do the job only once. But when a client is IE the servlet receives three requests! And one of them (seconds) is always result in connection reset by peer... error. Does anybody have any idea what is going on and how to fix it? I print headers of the requests to the log, so here is excerpts from the log file. This is log from netscape request: 'request(GET) - F:\Tomcat3.2\webapps\ROOT\insMovie.swt' 'Header: name='accept-language', value='en,ru'' 'Header: name='connection', value='Keep-Alive'' 'Header: name='accept', value='image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */*'' 'Header: name='host', value='localhost'' 'Header: name='accept-charset', value='iso-8859-1,*,utf-8'' 'Header: name='accept-encoding', value='gzip'' 'Header: name='user-agent', value='Mozilla/4.7 [en] (WinNT; U)'' Processed file 'F:\Tomcat3.2\webapps\ROOT\insMovie.swt', output size 34375 bytes, processing time 751ms, total time 761ms this is log from IE's (3 requests): 'request(GET) - F:\Tomcat3.2\webapps\ROOT\insMovie.swt' 'Header: name='accept-language', value='en-us,ru;q=0.5'' 'Header: name='connection', value='Keep-Alive'' 'Header: name='accept', value='application/vnd.ms-excel, application/msword, image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*'' 'Header: name='host', value='localhost'' 'Header: name='accept-encoding', value='gzip, deflate'' 'Header: name='user-agent', value='Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)'' Processed file 'F:\Tomcat3.2\webapps\ROOT\insMovie.swt', output size 34375 bytes, processing time 60ms, total time 70ms 'request(GET) - F:\Tomcat3.2\webapps\ROOT\insMovie.swt' 'Header: name='accept', value='*/*'' 'Header: name='host', value='localhost'' 'Header: name='user-agent', value='contype'' Connection aborted by peer: socket write error java.net.SocketException: Connection aborted by peer: socket write error at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:83) at org.apache.tomcat.service.http.HttpResponseAdapter.doWrite(HttpResponseAdapter.java:162) at org.apache.tomcat.core.BufferedServletOutputStream.doWrite(BufferedServletOutputStream.java:121) at org.apache.tomcat.core.BufferedServletOutputStream.write(BufferedServletOutputStream.java:192) at com.iv.flash.servlet.GeneratorServlet.send(GeneratorServlet.java:408) at com.iv.flash.servlet.GeneratorServlet.processTemplate(GeneratorServlet.java:292) at com.iv.flash.servlet.GeneratorServlet.doGen(GeneratorServlet.java:216) at com.iv.flash.servlet.GeneratorServlet.doGet(GeneratorServlet.java:174) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404) at org.apache.tomcat.core.Handler.service(Handler.java:286) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection(Ajp12ConnectionHandler.java:166) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498) at java.lang.Thread.run(Thread.java:484) 'request(GET) - F:\Tomcat3.2\webapps\ROOT\insMovie.swt' 'Header: name='connection', value='Keep-Alive'' 'Header: name='accept', value='*/*'' 'Header: name='host', value='localhost'' 'Header: name='accept-encoding', value='gzip, deflate'' 'Header: name='user-agent', value='Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)'' Processed file 'F:\Tomcat3.2\webapps\ROOT\insMovie.swt', output size 34375 bytes, processing time 90ms, total time 110ms -- Dmitry Skavish --- Boston, MA, USA tel. +1 781 370-6909 http://www.flashgap.com
Can't get webapps module to work
Hi, I have built and installed the newset webapp module. However, when I try to access anything I get the following error. I get this error even trying the examples servlets. Is this a config problem? or have I missed something during in the build/deploy? If I'm just viewing stuff its ok. Itrs seems that whenever some sort of request is made (like a post) the problem starts, and the module seems to just loop forever.

/ as path for my webapp
Hi there, I'd like to assign the / as path for my webapp (cocoon). How do I specify that? I tried to copy the servlet and mapping from the web.xml out of the cocoon.war, but with no success. It seems to me that it doesn't recognize the libraries then?!? Any thoughts? Mariano
