Check the stack trace and look for the jsp converted to java inside the
work/ tomcat directory to check wich line generated the error.
If you don't have a stackTrace surround all your jsp with a try/catch
%try {%
YOUR JSP ...
%} catch(NullPointerException npe) {
npe.printStackTrace();
}%
and check the tomcat log (console or catalina.out inside the logs subdir).
Good luck.

Re: null pointer exception when running mail example
My two cents follow. Make sure that your invoking your services consistently. Something like: localhost/MyWebApp/jsp_or_servlet or: 127.0.0.1/MyWebApp/jsp_or_servlet or: 128.43.10.19/MyWebApp/jsp_or_servlet Inconsistencies like these, can bring you headaches. since the default session management specs bind sessions to the url. If you change the url then you loose the session and hence you get errors like the ones you listed below.

Re: null pointer exception when running mail example
How I'm invoking the mail example is by entering the following as the URL: http://localhost:8080/examples/jsp/mail/sendmail.jsp If this were kwilliamsLinux (my machine name) instead of localhost, I'd definitely see that as the potential source of the problem (although I didn't think of that until I read your email). I searched the internet, and they all said to ensure that 127.0.0.1 localdomain.localhost localhost was in my hosts file, which it was. What I had to add was the 127.0.0.1 kwilliamsLinux I can't figure out why tomcat is needing that when running from a command line (and removing tomcat from the equation) doesn't. I think this issue is specific for linux as well. Kevin My two cents follow. Make sure that your invoking your services consistently.

Re: Null Pointer Exception - would you please take a look?
Alas, I do not have code to the JDBCRealm =( I figured that this would be a cut-and-dried problem -- either the JDBCRealm implementation or perhaps my driver behaving poorly. In either case, I figured someone would be able to tell right off my my description, but perhaps I described the circumstance poorly. It happens when I visit a page that has a security constraint.

Re: Null Pointer Exception - would you please take a look?
I'm getting really annoyed =) It seems you people haven't actually read my question thoroughly enough to actually understand what I'm doing. The thought crosses my mind that you see the subject and then just scan and put in some standard Oh he's an idiot - he needs to do this response. The problem is with a JDBCRealm! I do NOTHING to send/receive anything to/from the database. I was of the understanding that Tomcat did this when I configured the realm and set up the security-constraint. While I believe my XML to be valid and correct, I will happily post it for inspection if someone thinks it would help. Here is a sequence of what happens and the actors that are involved: Actors: Me and Tomcat Me: Enter url of page that is protected by a security constraint into my browsers address bar. Press enter. Tomcat: Returns to the client a page that looks like: !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN HTMLHEAD META http-equiv=Content-Type content=text/html; charset=windows-1252/HEAD BODYPRE/PRE/BODY/HTML (This is not what the actual page is - it's a JSP file - index.jsp - with much different content. Also notice I'm not calling a servlet! Even if I were, it wouldn't make a bit of difference at this point because Tomcat hasn't authenticated me! This happens when Tomcat should authenticate me - it is NOT my coding!!!) In my server log file, I have an error that starts off as: 2002-06-17 12:29:28 [org.apache.catalina.connector.warp.WarpRequestHandler] java.lang.NullPointerException at interbase.interclient.PreparedStatement.setString(Unknown Source) at org.apache.catalina.realm.JDBCRealm.credentials(JDBCRealm.java) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java) My catalina.out has no indication of anything having gone awry - it merely has status messages indicating that the server was started (why isn't there a timestamp in here?). Any ideas? Thank you for having actually READ THE ENTIRE MESSAGE so you UNDERSTAND my problem before having issued a reply =) Ack! I'm sorry but I'm frustrated by the responses I am getting - makes me wanna just jump up and down and scream at the top of my lungs ... Please - I BEG of you - clue me in here - any thoughts why this is happening? Again, I can post my XML if you think I need to.

Re: Null Pointer Exception - would you please take a look?
This may be to much to ask for - but are you able to get this to work with a different DBMS? On first glance, it appears you (not literally) might be passing null to the JDBC driver's setString() method and the JDBC driver can't handle the null value. Consequently - things explode. If so - it would be JDBC driver's fault and not tomcat.

Re: Null Pointer Exception - would you please take a look?
Hi Eddie, Have you tried accessing Tomcat directly and not going through Apache? I was having too much trouble using mod_webapp together with Apache and Tomcat due to that form-based authentication didn't work through Apache but it did directly with Tomcat. Maybe we should all use mod_jk instead. Is anybody running it on Mac OS X BTW?

RE: Null Pointer Exception - would you please take a look?
First, back-off. Yeah, maybe some people aren't reading your e-mails carefully, but some of us are supposed to be billing clients and not answering your e-mails. Second, an introduction to the art of reading stack traces. There's no problem loading your driver. If there had been, you would be getting a different error message. The connection is not null. Again, if so, you never your have gotten as far as you have. The statement is not null. If it was, the stack trace would finish one line earlier than it does. The problem is that setString() has been called and there's a NPE. My educated guess is that the String param is null. The username is the parameter there, BTW. Look at the Tomcat source. What puzzles me about your situation is that you say you're accessing a url (a jsp, right?) that you THINK is protected. What's the url and what does your web.xml file say? Tomcat is obviously trying to log you in via the JDBCRealm but you said you're not getting prompted to enter a username and password. That's a stumper to me. It at least explains why setString() might be getting a null param. With basic authentication, the browser remembers the login info and resubmits it on every request, I think. The only way to log out is to restart your brower. By default Tomcat caches the login info also, so you wouldn't see an attempt to hit the db unless you turned off this caching, which you probably didn't. So, I would say there's an issue with web.xml not doing what you think it should do but I can't put my finger on what it is. Post your url and web.xml contents. You might also look at the status codes in the access log. john -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]. org]On Behalf Of Eddie Bush Sent: Tuesday, June 18, 2002 1:57 PM To: Tomcat Users List; [EMAIL PROTECTED] Subject: Re: Null Pointer Exception - would you please take a look?

Re: Null Pointer Exception - would you please take a look?
But why would this be happening? I haven't even been presented with a prompt at which I could enter a usename/password! I understand what you are saying - but I'm not sure ... I'm not sure =) No, I don't really have another DBMS I can plug in easily. Let me go ahead and post my realm definition - maybe someone will see a problem with it: Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=interbase.interclient.Driver connectionURL=jdbc:interbase://host//path/to/my/data/file.gdb connectionName=validuser connectionPassword=validuserpswd userTable=member userNameCol=username userCredCol=passwd userRoleTable=member_role roleNameCol=rolename / Is this good? It's nested in an Engine element (WarpEngine) which is nested in a Connector element (WarpConnector) which is nested in a Service element which is nested in a Server element. Basically what I did was take the config file that came with Tomcat, cut out ALL of the stand-alone stuff - and leave the Warp stuff. Does it sound as though I've approached this poorly? It works for everything except this danged authentication! Thanks so much!

This is a known problem of interclient JDBC driver, they claim partly JDBC 2.0 compatibility, but i should say it JDBC 0.5 :) If you try firebiurd instead of 6.0 you try the jca driver at firebird.sourceforge.org it's a Type 4 driver you doesnt need interserver at all.. last time i tested it worked btw..

In my server log file, I have an error that starts off as: 2002-06-17 12:29:28 [org.apache.catalina.connector.warp.WarpRequestHandler] java.lang.NullPointerException at interbase.interclient.PreparedStatement.setString(Unknown Source) at org.apache.catalina.realm.JDBCRealm.credentials(JDBCRealm.java) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java) at org.apache.catalina.realm.JDBCRealm.authenticate(JDBCRealm.java) My catalina.out has no indication of anything having gone awry - it merely has status messages indicating that the server was started (why isn't there a timestamp in here?). Any ideas? Thank you for having actually READ THE ENTIRE MESSAGE so you UNDERSTAND my problem before having issued a reply =) Ack! I'm sorry but I'm frustrated by the responses I am getting - makes me wanna just jump up and down and scream at the top of my lungs ... Please - I BEG of you - clue me in here - any thoughts why this is happening? Again, I can post my XML if you think I need to. A couple of questions people have asked up to this point, along with the answer: Q: Are you passing a null string? A: I get this when I try to visit a URL that falls under a security constraint. It's a JDBCRealm. Tomcat handles this - it is not my code. Q: Are you sure the fields in your table match what Tomcat is expecting? A: Initially they didn't. My fields were of length 14 and Tomcat says they should be 15 -- but they're varchar, so does that really matter? I rebuilt the tables so that anything Tomcat uses matches exactly what the docs say - meaning I made my fields to be of length 15. I still get the same response - exactly the same response. Is this the JDBCRealm? I put my DB driver in common/lib - so Tomcat SHOULD be able to find it - right? Is this the appropriate spot? Is it possible (and how possible?) that this is my driver? I use this driver just fine doing JDBC stuff all the time - no problem. Thanks for your time!

First, back-off. Yeah, maybe some people aren't reading your e-mails carefully, but some of us are supposed to be billing clients and not answering your e-mails. Not trying to start any flames John. I'd just prefer that if someone doesn't have the time to read and understand my question that they not reply - that's all. When you look at the third message in a row that says Make sure you're not giving a null value or He isn't checking to make sure he has a valid connection it gets kinda exasperating. I understand people have things they have to do - that they get paid to do - and I fault nobody for that. Your previous reponse, to be honest, is the most useful one I have gotten until you sent this one - thank you for honestly trying to come up with a solution - I DO appreciate it. Second, an introduction to the art of reading stack traces. There's no problem loading your driver. If there had been, you would be getting a different error message. The connection is not null. Again, if so, you never your have gotten as far as you have. The statement is not null. If it was, the stack trace would finish one line earlier than it does. The problem is that setString() has been called and there's a NPE. My educated guess is that the String param is null. The username is the parameter there, BTW. Look at the Tomcat source. Yes - I agree and these were my thoughts as well - but why? =) Is it perhaps a mis-configuration on my part? I honestly believe I have the XML right. It works fine with a MemoryRealm - only when I go to a JDBCRealm does it start having problems. What puzzles me about your situation is that you say you're accessing a url (a jsp, right?) that you THINK is protected. What's the url and what does your web.xml file say? Tomcat is obviously trying to log you in via the JDBCRealm but you said you're not getting prompted to enter a username and password. That's a stumper to me. It at least explains why setString() might be getting a null param. With basic authentication, the browser remembers the login info and resubmits it on every request, I think. The only way to log out is to restart your brower. By default Tomcat caches the login info also, so you wouldn't see an attempt to hit the db unless you turned off this caching, which you probably didn't. So, I would say there's an issue with web.xml not doing what you think it should do but I can't put my finger on what it is. Post your url and web.xml contents. No - I don't think it's protected =) I know it's protected. If I access it with a MemoryRealm everything works as expected. It's only when I introduce the JDBCRealm that things get out of whack. I always restart my browser =) Heck I've even tried rebooting. Oh - and I always close OutlookExpress when I close IE too - I've had things that cause me to be suspicious of it causing things to be cached between browser session. Call me over-paranoid - but I like to be extra sure =) My web.xml is: ?xml version=1.0 encoding=ISO-8859-1 ? !DOCTYPE web-app (View Source for full doctype...) - web-app - welcome-file-list welcome-fileindex.jsp/welcome-file /welcome-file-list - security-constraint - web-resource-collection web-resource-nameadmin/web-resource-name url-pattern/*/url-pattern /web-resource-collection - auth-constraint role-namemanager/role-name /auth-constraint - user-data-constraint transport-guaranteeNONE/transport-guarantee /user-data-constraint /security-constraint - login-config auth-methodBASIC/auth-method realm-nameAuthentication Test/realm-name /login-config - security-role role-namemanager/role-name /security-role /web-app You might also look at the status codes in the access log.

Hi Eddie, I use Interbasse to do what you are trying, but directly to Tomcat, so I know it can be done. My server.xml entry follows. The only thing I see different is that you have two forward slashes after the host name. Is this a typo? Does this work with your other JDBC apps? I'm accessing a database on a Solaris system so Windows would be a little different. The error message you are getting is from the Interbase driver so Tomcat IS finding interclient.jar. It is basically saying that it is getting a bad filename The only other thing I can think of with Interbase is that you have to be sure that file.gdb has granted read authorization to username on your member table.

Re: Null Pointer Exception - would you please take a look?
Yeah - it works fine except when I use it in this context. The double // after the host is a ... well it's like this: =) protocol:subprotocol://server/path ... and because my path starts with a /, I have two of them - works super on everything else. I run on RHL 7.2 =) The first one is a delimiter - the second is necessary to indicate the path. ... at least that's how I've always done it. I read it somewhere I think, but I couldn't tell you where. I just downloaded Firebird - and upon looking at the docs I think I quite like it. I'm in the process of uninstalling interclient, as it wasn't an RPM install - so I guess I get to do that part by hand =) Ignacio tells me I won't need interserver anymore, so ... I want to be sure everything is as 'tight' (security-wise and file-system-wise) as it can be. I abhor needless clutter floating around ... unless it's in my personal directory ;) lol From the looks/sound of things, I can either use the driver approach or I have the option of binding a datasource into JNDI - InterBase didn't offer that, so it's a step ahead, I think. I figure the JDBCRealm will use the driver approach (since the only JNDI lookup supported by TC is currently LDAP), and then I can just have my initialization servlet bind a reference to the appropriate POOLING datasource (I liked that part =) provided by Firebird into JNDI and have the rest of my app get it from there. I wish the TC guys would let you configure a pool for the JDBCRealm. I know ... I know ... it's in the works. That'll be really nice!

We are using Jason's MultiPart classes to upload files. They tested out
fine on our NT development platform using Sun JDK 1.3. Our production
environment is Sun Solaris on Sparc, using Sun JDK 1.3. On Sun, upload of
text files work fine, but trying to upload a Microsoft Word document results
in a null pointer exception. I haven't debugged this yet, but I notice a
file of zero size with the correct name in the upload directory, so the file

We have a different app on a different Sparc box using JDK 1.2.2, and it
appears to work okay. Are there any known issues with the Multipart classes
on JDK 1.3 on Sparc?
