manager app permissions issue
Hello,
I'm trying to use the manager app but recieve the following error:
java.lang.SecurityException: Servlet of class
org.apache.catalina.servlets.ManagerServlet is privileged and cannot be loaded by this
web application
Did some looking around and the only thing I can come up with is changing the
catalina.policy file. So I added:
grant codeBase file:${catalina.home}/webapps/manager/- {
permission java.security.AllPermission;
};
to catalina.policy, but that did not fix it.
Has anyone seen this before and no what the problem is?

Is it possible that you made a change to the xml file that is not showing up in the

The include that you are using is a compile time include meaning that if you change
the included xml file without changing the including jsp file then those changes will
not be reflected.

Subject: Not getting CSS with XML
I'd be very grateful for any advice regarding a CSS problem that is
puzzling me.
Our setup is Tomcat 4.0.6-LE on a Sun running Solaris 8.
We have a webapp with the href base set as /acsam.
In the acsam webapp directory we have this very simple test CSS
stylesheet (mary.css):
paragraph {
display: block;
border: solid red;
line-height: 2
}
.green {color: green}
We also have a simple html file (mary.html):
?xml version=1.0 encoding=UTF-8?
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Strict//EN SYSTEM
http://www.w3.o
rg/TR/xhtml1/DTD/xhtml1-strict.dtd
html
head
titleCSS Test/title
link rel=stylesheet type=text/css href=/acsam/mary.css/
/head
body
div
p class=greenMary had a little lamb./p
/div
/body
/html
If we access this file directly (ie. [path]/acsam/mary.html)
it displays
correctly - the text is green as dictated by the mary.css stylesheet.
Similarly, if we access mary.html by using an include statement in a
JSP, like this (mary2.jsp):
%@ include file=mary.html %
it displays correctly as before.
Now to the XML. We have a simple XML file (mary.xml):
?xml version='1.0' encoding='UTF-8'?
?xml-stylesheet type=text/css href=/acsam/mary.css?
document
paragraph
Mary had a little lamb.
/paragraph
/document
If we access this file directly (ie. [path]/acsam/mary.xml)
it displays
correctly, with a red border around the paragraph, as dictated by the
mary.css stylesheet. However (here's the puzzling part), when
we try to
access mary.xml with a very simple JSP file like this (mary.jsp):
%@ include file=mary.xml %
it does NOT display correctly. For some reason the ?xml-stylesheet?
link is not getting the CSS, even though it does get it when we access
the XML file directly. As you can see, the path to the CSS file is the
same in both mary.html and mary.xml.
Can anyone explain why accessing the XML via the JSP doesn't
get us the
CSS styles?
Thanks,
Paul.

Tomcat 4.1 and IIS 5
Wazzup, Problem is that IIS is not serving up JSPs via Tomcat. Tomcat runs perfectly standalone. IIS is up and running. Jakarta filter shows a green light. The isapi redirect log shows, all is good. Found the mapping, etc. The error message reported to the browser is Unable to load module. So I thought maybe it was a problem with the isapi redirector. Strange because the isapi log shows all is good. The isapi redirector that I was using was from the connector binaries folder. So I decided to go get the one from 3.3.1 and try that. After restarting Tomcat and IIS with the new dll in place, IIS locked. Maybe I should have thrown a reboot in there before switching dll's. Has anyone gotten the isapi_redirector.dll from the connector binaries folder to work?

Subject: one servlet question
Hi,
I have to write a servlet which will be a base servlet
for all servlets in my applications.
I have a class called GetConnection which gets the
connection from servletcontext depending upon some
parameters in the session, so i have go send
servletcontext, and session to this class.
now the question is should i create the instance of
this class in init method of the servlet or define a
seperate method and create the instance of that class
from doget or dopost method of the child servlet,(this
servlet will extend the base servlet).
i have this doubt because if i create the instance of
this getconnection class in init method, it will be in
memory for the full life cycle of servlet(i.e. untill
i stop the app server).
so if i extend this base servlet for other 100 child
servlets, then there will be 100 instance of
getconnection for life cycle of servlet.
so am i thinking in the right way???
any suggestions
Ashish

But I have a couple of questions that may help us understand the problem better. If you're reading from a CSV file, why do you need a DB connection? Couldn't you just open a FileReader, read a line at a time, use StringTokenizer to get your tokens? This approach will be very fast and use very little memory, even for huge CSV files, because only one line of the file has to be in memory at a time and the StringTokenizer for a String is a small object. This is what I'm doing. I actually used jakarta-oro to split the lines. In fact, you problem statement says No database work is done at this point... so why all the discussion about Oracle connection pooling? Jumped the gun a bit I guess, retrieving db connections and inserting into a database is the last thing I do and is when I notice the Tomcat process is about to die. The next part would be the connection pooling implementation questions. Did you try to get a new connection each time and not go through the pool? That would degrade performance significantly (although you could just get one connection at the beginning and use it until you're done), but maybe memory behavior will be better? I will be removing the pooling and just getting new connections to see if this makes a difference today, and will post results. Did you try an alternative connection pooling implementation instead of Oracle's? One such as commons-dbcp or PoolMan? If nothing else, it would allow you to pinpoint the blame on the Oracle connection pooling implementation. I will be doing some performance tests with different pooling implementations soon. Will post my results if anyone would like to see them. If anyone knows of benchmarks already available, please let me know. And finally, are you trying to do any fancy cloning of data in the file / objects in the ImportManager? no This shouldn't be a tough problem ;) I'm sure we can figure this out...

Just tested getting a new connection, the system will still crash. I've noticed the smaller the file import, the longer it takes for Tomcat to crash after I've done an import. i.e. a file with 12 lines in it will import successfully, then I can get maybe 20 more connections before Tomcat crashes. Where as a file with 50 lines in it will cause Tomcat to crash immediately after the import, anymore lines than that and the import will fail before the import completes. The number of lines that will succeed is variable. Sometimes 50 lines will get imported, sometimes Tomcat will crash before I can import 50 lines. BTW, Tomcat is not reporting any errors in the logs.

Subject: Re: problems with Connections
I don't think it is TOTALLY offtopic, since the problem
occurs within
Tomcat...
From your description of the problem and your design
approach, I'll bet it
would happen to you in a long-running non-servlet application as well.
and when I close tomcat all the connections and cursors are
released...
Exactly what you'd expect if your application is leaking open
connections,
statements, or result sets.
as I said in my email I close ALL ResultSets and Statements
in finally
blocks...
Fine, I'll take your word for it ... but missing a case would easily
account for what you are seeing. (In the particular case of Oracle, a
cursor is allocated for each result set, which is not
released until the
result set is closed).
as for closing the Connection... can I use the finalize()
in the DAO*
classes to use the method that returns the Connection to
the pool?? Cuz
I can't see anywhere else where I'd be able to do that...
The right design pattern is to acquire a connection, do whatever
processing is required, and immediately release it. For example:
DataSource dataSource = ...; // Acquire reference to
connection pool
Connection conn = null;
try {
conn = dataSource.getConnection();
... perform SQL operations as necessary ...
conn.close(); // Return connection to the pool
conn = null;
} catch (SQLException e) {
... deal with problems ...
} finally {
if (conn != null) {
try {
conn.close(); // Return to pool even if an exception occurred
} catch (SQLException e) {
;
}
conn = null;
}
}
Waiting for the finalize() method to clean up just occupies resources
needlessly until the garbage collector gets around to running -- this
by itself could easily exhaust your available connections in a busy
environment. It also assumes that your JDBC driver's
implementation of
the finalize() method knows that this Connection was stored in a pool.
That seems like a really shaky bet.
A primary goal of your designs should be to minimize the
amount of time
that you have a database connection allocated to the processing of a
particular request -- connections are expensive to create, and there's
always an upper limit on how many your database will support.

Tomcat Crash
I'll try to make the circumstances of the crash as brief as possible. What I'm doing: Importing data to my app from a comma delimited file. The data is parsed out of the file (one pass through the file only) put into objects and stored as static members of an ImportManager class. The app then asks the user about the data, make some corrections, delete entries, etc. No database work is done at this point, only manipulating/removing objects from a static Map in the ImportManager class. The crash occurs on a doImport() method or shortly after. This method gets a connection from an Oracle connection pool (the pooling that comes with their drivers). The import will succeed if the data file size is small, roughly 50 lines and then the system crawls for a bit before dieing. Seems like a memory leak. Does anyone know of any problems with the connection pooling in the Oracle JDBC drivers? I increased the maximum heap size for tomcat service to 256MB, which should be more than enough for my development environment. Here's a sample of the logging that I set up to monitor the import: ** Connection Retrieved, Free Memory: 1008416 Total Memory:4079616 ** Line: 47 PR completed: 1029879840 ** Line: 48 Squadron completed: 1029879840 ** Line: 48 Flight completed: 1029879840 ** Line: 48 Ratee completed: 1029879840 ** Line: 48 Rater completed: 1029879840 ** Connection Retrieved, Free Memory: 1276760 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1137368 Total Memory:4079616 ** Connection Retrieved, Free Memory: 973464 Total Memory:4079616 ** Connection Retrieved, Free Memory: 809640 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1185096 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1007808 Total Memory:4079616 ** Line: 48 PR completed: 1029879840 ** Line: 49 Squadron completed: 1029879840 ** Line: 49 Flight completed: 1029879840 ** Line: 49 Ratee completed: 1029879840 ** Line: 49 Rater completed: 1029879840 ** Connection Retrieved, Free Memory: 117 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1026288 Total Memory:4079616 ** Connection Retrieved, Free Memory: 853176 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1203568 Total Memory:4079616 ** Connection Retrieved, Free Memory: 1064440 Total Memory:4079616 ** Connection Retrieved, Free Memory: 882136 Total Memory:4079616 ** Line: 49 PR completed: 1029879841 ** Connection Retrieved, Free Memory: 990840 Total Memory:4079616 ** Connection Retrieved, Free Memory: 876248 Total Memory:4079616 Thanks for any help. -Dave -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Design question
Another option might be to use LDAP to query a windows active directory, if you're using that.

This means that users with in your domain can be automatically authenticated (by using Windows Intergrated Authenticaton in IIS). There are several ways to upload files to a server, one is by using MultiPart Requests (Method POST). All you need is a MultiPartRequestParser and then you can parse the files from the request and do what ever you like with em, such as upload the files to a remote server. If you need to use NTLM authorisation for this It can get little bit complicated. In theory you should be able to do it anyway, but not with out the user giving out his username/password/domain combination, to authenticate against the remote server. Then for step 2 (downloading files from a remote server authenticated with NTLM) you could write a servlet that acts similar to a proxy. This could be achived by using the http://www.innovation.ch/java/HTTPClient/ along with http://www.innovation.ch/java/ntlm.html and last but not least http://www.luigidragone.com/networking/ntlm.html hope it helps [EMAIL PROTECTED] -Original Message- From: Raju Lokhande [mailto:[EMAIL PROTECTED]] Sent: 19. ágúst 2002 17:01 To: Tomcat Users List Subject: Design question Greetings everybody, I am doing some research on possibility of using Tomcat to do a project.

Subject: RE: Quick Question
IMO, it seems like a bad idea to me to tie your bean
code to a servlet context unless you REALLY need to.
To me, a better way would be to put the file in a
directory under classes, and use the classloader of
the current thread to get to the file.
This way, you do not need servlet.jar to use your bean
if you every decide to use it outside of a servlet.
This is a very simple process. Here is an example:
private InputStream getFile(String name){
return Thread.
currentThread().
getContextClassLoader().
getResourceAsStream(name);
}
To read a properties file classes/myprops.properties
for instance, you just do this:
Properties p = new Properties();
p.load(getFile(myprops.properties));

RE: Configuration for High TPS
You can set up an event listener to cache this data when the context is initialized.

Quick follow up on this. I'm testing a servlet I've written that does some caching, and is very quick once it has cached all of its data. During the first run, I test it going 40 TPS (over several thousand requests). Then I start upping the TPS (same set of requests), and I plan to stop at 200 TPS. Now here's an intresting problem. My tool has reported on several runs that it cannot connect within only a second or two of starting the tool. With an accept count of over 1000, I find this rather odd as it should take at least 5 seconds at 200 TPS to fill an acceptCount of 1000 (typically the lowest I've set acceptCount). I normally run into can't connect errors early during a test run, when my servlet is still caching its data (still working on a way to better handle that problem also).

RE: Trying to work with JDBC
He's not using oracle's jdbc drivers, although maybe that is something to try. I recommend getting the newest drivers from oracle because it has been reduced to a single jar file, is much smaller (I think the old drivers were like 8MBs the new ones are around 2MB), and there is support for the jdbc 2 optional packages which means that connection pooling is supported. -Dave -Original Message- From: Mike Jackson [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 08, 2002 3:42 PM To: Tomcat Users List Subject: RE: Trying to work with JDBC First and foremost, don't unjar the oracle classes. They're fine in the jar files as is. You'll just need to put them in the lib directory under your WEB-INF or in tomcat's lib directory. Also another thing to watch for is what jar's you're putting out there. You only need the classes12.jar and nlscharset12.jar generally. If your jdk isn't 1.2+ then you'll want the 11 series drivers. Don't put both of the versions in your classpath however, you can sometimes get weird results that way. Second, your driver is ok, but the jdbc url is all wrong. It should be something like the following: jdbc:oracle:thin:@server-name-or-ip-address:1521:ORCL Third, I'm not sure what you're attempting to do with the server.xml file, unless you're attempting to use the jdbcrealm authentication you don't need to do anything with it (I don't do jdbcrealm, so you'll need to ask someone else). If you are attempting to use it (jdbcrealm) then you'll need to put the oracle jar files into the tomcat lib directory. If you put them in the webapp tomcat won't be able to see them and you'll not get anywhere. As for your Java Beans and JSPs, you might have better luck after you fix the url that you're using to connect to the database.

This is sort of off-topic, but I don't know of a better forum targeting Java web/servlet programming. If anyone does know of one, could you let me know? I'm basically wondering if others have found effective ways to avoid the tempting but bad practice of loading up the session with all sorts of attributes. I often find myself needing some Bean or other object for maybe 2 or 3 requests, and, rack my brains as I may for an elegant way of passing the object along without putting it in the session, I usually end up with nothing more than a headache and 1 more attribute in my session. :( I'm developing with an MVC approach, with Struts for more recently developed apps and a similar custom framework for our older apps, but I just can't seem to see a way to get around this problem. I would love it if there were an object like a thisRequestAndTheNextOne object, where attributes would stick around for the current request and subsequent request, and then the controller could get objects from the previous request and determine if it should put them in the new thisRequestAndTheNextOne object for the current request. I don't know if that makes sense to anyone else, but, nevertheless, does anyone have any ideas to do what I'm trying to do? Does anyone else feel my pain? ;) Thanks, -Jeff -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

You can get it from the tomcat 3.3 distribution Here are possible problems (use the ajp connector docs for IIS as reference) http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html (bottom half of page) Check your registry entries, typos can be a problem of course, but probably not the problem since you have a green arrow in IIS. Check the uriworkermap.properties file, you need something like: /examples/servlet/*=$(default.worker) /examples/*.jsp=$(default.worker) Also, can you view the examples on port 8080, i.e. not going through IIS? If you can't do that, then it they obviously won't work through IIS and your problem is elsewhere. -Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, July 29, 2002 3:21 PM To: Tomcat Users List Subject: RE: Problem with IIS Win2K + Tomcat You mentioned mod_jk.

RE: Tomcato4.0.4 and included jsp compilation problem
There are 2 kinds of includes, one is compile time, one is runtime. If you're using a compile time include, i.e. %@ include file=include.jsp% then you need to update the file that is calling the include. For example, 'touch file_that_includes_something.jsp'. This is not a bug. -Original Message- From: Ashish Kulkarni [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 25, 2002 10:31 AM To: Tomcat Users List Subject: Tomcato4.0.4 and included jsp compilation problem Hi, I m using tomcat4.0.4 , i found out today that when i modify the included jsp , tomcat does not recompile it. i.e. I have suppose a jsp called test.jsp and i include a jsp called test1.jsp.

RE: determining URL selected prior to redirection for j_security_check?
Yeah, I think you might be better off with implementing your own security mechanisms
for this.
Although, maybe request.getHeader(Referer) has something in it? Interesting to note
that this differs from javascripts document.referrer which has 4 r's.

RE: How to close a response?
Well not sure what to tell you about your particular issue, but I experienced a very
similar problem (double page, or at least partial double page). In a JSP page
something like this:
%@ include file=header.jsp %
%
// check login
if (!user.loggedIn()) {
response.sendRedirect(login.jsp);
return;
}
%
The problem is that the response content is sent along with the response headers. I
think this is appropriate, but produces undesirable results in IE (double page). The
solution was to be sure that any redirects were sent and the method returned before
any HTML was added to the response, like this:
%
// check login do this before sending any HTML to response
if (!user.loggedIn()) {
response.sendRedirect(login.jsp);
return;
}
%
!-- now HTML is fine --
%@ include file=header.jsp %
I'm not sure but I think that a call to reponse.close() will flush anything left in
the buffer then close. The fact that double clicking a link produces the same result
is strange (and I've never seen that), because you would think that the first response
never gets a chance to do anything, or just gets ignored by the browser
Hope this helps
Dave

Subject: How to close a response?
Hi,
I need to close the response completely. In some case I need to avoid any
process write to response output.
Using
response.getOutputStream().close();
response.getWriter().close();
response.reset();
do not help.
Thanks for any suggestions.

public class FormBean implements Serializable {

public FormBean() {}
public String getUserName() {

}
public void setUserName(String uname) {
this.userName = uname;
}
}
NO MATTER WHAT, as soon as I access the jsp page. This error comes up.
Generated servlet error: C:\jwsdp-1_0\work\Standard
Engine\localhost\messagesmith\en\users$jsp.java:126: Undefined variable or
class name: FormBean out.print( FormBean.getUserName() );
It certainly seems that TC cannot find the FormBean class which lives here:
C:\jwsdp-1_0\webapps\project\WEB-INF\classes\beans.
I've changed that scope attribute to application or page, but it doesn't
change.
With TC3.x I had to do some configuration in the conf/server.xml file, but
this doesn't seem necessary w/ TC4. All the same I've adding the following
context to the server.xml, but it doesn't help.
Context path=/project

Anyone have any ideas? It is killing me. Again, I can instantiate the
FormBean class from within servlets, but not from JSP.

uploading non-ascii files
I have a serlvet that accepts a multipart form submission. Inside the request is a file that is to be decoded and stored on the server. My problem is that it doesn't work with binary (non-ascii) data but does work with ascii data. I'm using JSPSmartUpload, which works fine on IIS, but with Netscape Suite Spot, it does not. I'm using tomcat3.2.3 Is this a problem with Tomcat or Netscape Suite Spot? Anyone got any ideas, suggestions, experience with this before? Been working this issue for several days, searched the web, found nothing particularly useful. I did find some bug reports searching the tomcat-dev list. Apparently this was a bug, awhile back but is fixed now. Does it still not work with Suite Spot? -Dave -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
Repost: Can't upload binaries with JSPSmartUpload, Tomcat and Netscape Server
Can upload text files, binary files fail and stderr.log says: IOException: Connection aborted by peer: socket write error I don't know if that means that the connection to the client's browser failed or possibly the connection to Netscape Server failed. Like I said, this only happens on non-ascii files. jpg's, zip's, etc. Searching through this mailing list archive indicates there was a bug matching this exact problem with mod_webapp?? and a fix posted. My question is: Will upgrading to a newer version of Tomcat fix this problem? I'm currently using 3.2.3 and considering 3.3. That's brings the next question which is will the nsapi.dll I currently have (got it from the 3.1 tree) work with newer versions of Tomcat. Previous post was: I'm locked into Netscape Server for the moment. I can upload text-files fine with jspsmartupload, but when I try to upload binaries it fails. Exact same code works on Tomcat/IIS server, but does not work on Netscape Server. Thought it might have something to do with a proxy, but it didn't. Does Netscape Server block binary file uploads or have the ability to do so? Not much on the web about this. Wondering if anyone else has run into this or something similar. -Dave -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

class cast exception
I receive a class cast exception pulling something out of a session after I recompile a servlet. The object I'm pulling out of the session is of a class that has not changed. i.e. I changed a servlet not the class of an object in the session. Restarting Tomcat fixes the problem. This seems like a bug to me, has anyone else noticed this behavior?

RE: class cast exception
The scenario is this: JSP page creates a an object and puts it in a session. A servlet handles the action of a form and retrieves the object from the session. The class of the session object in the session has not changed and is located in the web-inf directory. If I recompile the servlet, it will give me a class cast exception. Sometimes if I compile an unrelated class. It will still throw a ClassCastException forcing me to restart Tomcat everytime I recompile. Seems like a bug, or maybe something that could be done differently to facilitate development. -Dave -Original Message- From: Craig R.

This will absolutely happen if you are using classes out of a shared library directory instead of within the webapp, or if you are somehow maintaining references to object instances created with the old class and trying to use them after the reload.

RE: Tomcat is very slow when used with Netscape browser
It's not Tomcat that is slow, it's netscapes rendering engine. In other words, the wait is probably for netscape to figure out how to draw the page.

The pages will then run properly. I'm using Tomcat-3.2.3 on Windows NT with an ISAPI redirector for IIS. The JSP application I'm working on is a slightly modified version of Jive Forums 1.2.4.

RE: url relative to directory path?
One idea is to make the application your root context. You will still need to use http://www.qbus.co.nz/servlet/servletName or else do the mappings. If you don't like maintaining the list, write a script to maintain it for you. Should be no problem removing and adding mappings considering this is an xml doc.

setting default pages for Tomcat

RE: Question about WAR and application deployment
If you use a file URL then it assumes that you are pointing to the file or directory on the machine (server). That means you have to put the application on the server first, FTP, or some other means. If you're working locally it's much easier. If you use some other url for the war parameter as in 'http://someserver/something.war' it will try to retrieve the file from that spot and install it. You would later reference your servlets, jsp from the path as in http://localhost:8181/text/index.jsp Hope this answers your question.
