Re: Persistent Connection
Thanks A lot Andrew and Mike for providing useful information. But Just for my knowledge I would like to know, What IIS or Apache doing specially so the connection closes with them and not with Tomcat. Any special protocols they are following or what? I have to compulsory use only tomcat and not apache. And mine is a networking application so these sockets are concerend for client. IS there any solution for it, when using only with tomcat or I have to accept this as a fact and work with it. Thanks Again.

What happens (as I understand it) is that once your app has closed the connection (page is done or whatever), the stack will hold the connection in a TIME_WAIT state to prevent the other end, the client, from reconnecting to the same port. So the problem isn't really tomcat, its the TCP/IP stack. However I've also found that under unix if you're using apache+tomcat you don't have a ton of TIME_WAIT sockets on the webserver. Apache apparently sets a parameter to eliminate the TIME_WAIT sockets, either on close or on open of the socket (I don't know which). So what you might want to do is run IIS or Apache in front of tomcat. I don't know that IIS does the same thing as Apache in regards to the sockets, but if it does then it'll work nearly as well in front of tomcat. But there is a slight problem here as well, you need to be sure that you're using APJ13 not APJ12 as APJ12 will open a new connection for each web access that tomcat handles. And in that casey you'd get more TIME_WAIT sockets. APJ13 multiplexes the requests over one persistent socket, so you don't have the extra overhead of opening the socket on each request, or the TIME_WAIT socket lingering there for some time period. Also, just as a FYI, under unix you can change the TIME_WAIT time period but it's not recommended that you do so. The default time period is about 4 minutes as I recall. You can probably also change it under windows, but I wouldn't have a clue how to do that. --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: Taral Shah [mailto:[EMAIL PROTECTED]] Sent: Friday, August 16, 2002 2:40 AM To: Tomcat Users List Subject: Persistent Connection I am using tomcat 3.3 Now I am calling one jsp which loads an applet, internally that applet uses url connection to fetch data.

Re: retrieving HttpSession in Filter? ServletResponse.setContentLength()?
hi craig. thanks for your reply. after digging deeper, i now know what's happening. it's quite strange. i'm calling tomcat from a (mobile) java client (not a web browser) and the client needs to know exactly how many bytes are being sent back to it by the server. when i call HttpServletResponse.setContentLength(##) in the servlet, the client receives the data without problem. however, my filter is doing post-processing on what the servlet wrote before sending the response back to the client. as such, i change my servlet code to *not* set the content length, and instead, the filter calls ServletResponse.setContentLength(##) before returning the response to the client. however, the client hangs for about a minute b/c it can't determine the length of the data being sent back from the server. so it seems that the problem lies in the filter when it calls ServletResponse.setContentLength(##). the problem doesn't happen with a normal web browser, as (i believe that) web browsers are able to somehow determine the size of the data being returned from the server (whereas the mobile java client that i'm working with isn't able to determine the size; thus the requirement to set the content length). do you have an idea of why this would be happening? thank you.

RE: RMI and TC4.x (Really classloader stuff)
Thanks for your comments Greg. Now at least I know what's going on. I'm going to attach these comments to the bug log. Thanks. Dave. -Original Message- From: Greg Trasuk [mailto:[EMAIL PROTECTED]] Sent: 10 August 2002 04:54 To: 'Tomcat Users List' Subject: RE: RMI and TC4.x (Really classloader stuff) Hi David: I'm in the same boat trying to use RMI and/or Jini from Tomcat. This isn't a complete answer to your question, as I'm still investigating the issue, but I'm posting what I know so far in the hope that it might help in your own solution, and also generate discussion that will guide my exploration. When all is said and done, if there's interest, I can post a Catalina-RMI HOWTO sort of document. Although I didn't try to run the test case that you attached to your bug report, I did take a look at it, and I think I know what's going on. Here's what I know so far (most of which you probably know already, but I'm summarizing for other folks on the list): When you pass an instance of some Serializable class as an argument to an RMI call (e.g. passing a command object, as in your test case), the RMI subsystem will serialize the object with an additional annotation indicating the locations from which the class's bytecode can be downloaded. When you pass an exported object (e.g. a server object or an object that will receive callbacks from remote objects), the RMI subsystem creates and serializes a proxy object (otherwise known as the RMI stub object) in place of the actual object. In either case, the remote RMI subsystem has to load the class that is called out in the serialized instance. It does this by calling the RMIClassLoader. The RMIClassLoader object first tries to find the class locally (i.e. in the default classloader). If it can't find it locally, it searches in the list of locations contained in the annotation mentioned above. If the required class is available locally, no further headaches are caused, which may be why some people have had no problems using RMI under Tomcat - they probably had the serialized classes and/or proxy classes in the standard classpath/classloader setup. And there we find our problem. (At this point you might want to have a look at the JSP snippet below) The annotation is determined by RMIClassLoader. According to the RMI and Object Serialization FAQ in the JDK1.31 API docs, If the _Stub class was loaded by an RMIClassLoader, then RMI already knows which codebase to use for its annotation. If the _Stub class was loaded from the CLASSPATH, then there is no obvious codebase, and RMI consults the java.rmi.server.codebase system property to find the codebase. If the system property is not set, then the stub is marshalled with a null codebase, which means that it cannot be used unless the client has a matching copy of the _Stub classfile in the client's CLASSPATH. If we're running a standalone application (and I believe also in Tomcat 3.x), we're using the system class loader, which has no obvious codebase, so the java.rmi.server.codebase property gets used. But what's the class loader used in Tomcat 4.x? I looked at the source code for Tomcat 4.0.1 (happens to be what I have on hand), and o.a.c.loader.WebAppClassLoader extends from o.a.c.loader.StandardClassLoader, which extends from java.net.URLClassLoader, which has a method called getURLs(). The WebAppClassLoader.getURLs() method returns a list of all the repositories it will search when trying to load a class on behalf of the web app. This list calls out all the jar's in WEB-INF/lib, common/lib, etc. Having not seen the source for RMIClassLoader, I suspect that the getClassAnnotation(..) method checks to see if the classloader for the supplied class is a URLClassLoader, and if so, uses the results of the getURLs() method call as an obvious codebase. This suspicion is supported by the last part of the JSP, where I create a classloader that extends from URLClassLoader but overrides getURLs() to return a phony url. The phony url shows up as the class's annotation. So the exact error you quoted in the bug report shows something about a protocol missing MalformedURL exception, which is caused by the fact that the urls to the repositories contain spaces, since the RMI annotation is supposed to be a space-separated list of URL's. Thus the annotation doesn't get parsed properly. This may be a bug in Catalina's class loader (i.e. should the returned urls have the spaces encoded to '%20'?) or possibly in the way RMIClassLoader uses the results of getURLs(). But it's not the problem. The problem is how to get our codebase into the annotation. Clearly the java.rmi.server.codebase property is not used, since the class loader has a codebase. But setting a system property doesn't feel right to me anyway, since in a webapp scenario,
Precompilation
Hi,
I currently recompile all my jsp's using jspc and update the entries in
web.xml as created by jspc.
This is fine but not quite what I want. One of the problems is that my
default welcome page is index.jsp which, of course, is
no longer there when the file is precompiled. I have got around this by
having a index.html that redirects after 0 secs to index.jsp.
Any solution to this?
I would like to be precompile so that all jsp go into
localhost/work/applicationfred$jsp.{java,class} as tomcat does. Any easy
way to do this?

Re: java-compiler for Mac?
Yes, there are a few! What version of the OS are you talking about? OS X comes with a complete JDK 1.3.1 installed. OS 9 and before had a downloadable Java runtime, called Mac Runtime for Java, or MRJ, that could be installed. (The current incarnation is also called MRJ, btw, but since it's not a separate install, it's transparent to the user.) The OS 9 JVM is only JDK 1.1.8, though. You can download it here: http://developer.apple.com/java/download.html. OS X is the way to go if your friend has any reasonably modern Mac. You can also run Jikes on OS X, if you don't want to use the Sun+Apple javac. Incidentally, Tomcat runs great on OS X. For a howto, please see my website: www.javaosx.com.

RE: Too many threads
Hi, The threading implementation of the JVM depends on the OS to some extent. Linux uses native threads as opposed to green or p threads, so you see more processes at the OS-level. You can google search for any of the above terms and you'll find a ton of references. For the tomcat configuration reference regarding acceptCount, minProcessors, and maxProcessors, all of which affect the number of threads used by tomcat, see: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/http11.html Yoav Shapira Millennium ChemInformatics -Original Message- From: Ronaldo [mailto:[EMAIL PROTECTED]] Sent: Saturday, August 17, 2002 10:17 AM To: Tomcat Users List Subject: Too many threads Hi, I'm developing a web aplication with jsp and servlets, and I'm beging to use tomcat.

RE: retrieving HttpSession in Filter? ServletResponse.setContentLength()?
if you are using a response wrapper, are you overriding setContentLength() and never calling super.setContentLength()? Charlie -Original Message- From: tek1 [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 5:16 AM To: Tomcat Users List Subject: Re: retrieving HttpSession in Filter? ServletResponse.setContentLength()? hi craig. thanks for your reply. after digging deeper, i now know what's happening. it's quite strange. i'm calling tomcat from a (mobile) java client (not a web browser) and the client needs to know exactly how many bytes are being sent back to it by the server. when i call HttpServletResponse.setContentLength(##) in the servlet, the client receives the data without problem. however, my filter is doing post-processing on what the servlet wrote before sending the response back to the client. as such, i change my servlet code to *not* set the content length, and instead, the filter calls ServletResponse.setContentLength(##) before returning the response to the client. however, the client hangs for about a minute b/c it can't determine the length of the data being sent back from the server. so it seems that the problem lies in the filter when it calls ServletResponse.setContentLength(##). the problem doesn't happen with a normal web browser, as (i believe that) web browsers are able to somehow determine the size of the data being returned from the server (whereas the mobile java client that i'm working with isn't able to determine the size; thus the requirement to set the content length). do you have an idea of why this would be happening? thank you.

Re: Tomcat 4.0.4: Unnecessary $TOMCAT/temp/ directory?
It is done for security reasons so that the JVM instance for Tomcat isn't using the same temp directory as other applicaitons on the system. Also so that there is a common temp directory path that is system neutral. This is more secure when you lock down Tomcat with the SecurityManager and a strict catalina.policy. Regards, Glenn Eddie Ruvinsky wrote: Thanks Glenn. The following Java API link has a quick blurb about the java.io.tmpdir system property: http://java.sun.com/j2se/1.3/docs/api/java/io/File.html#createTempFile(java.lang.String, java.lang.String, java.io.File) The JDK sets the default value for this property to be /tmp on Unix and c:\temp on Windows. So, it does not seem necessary to override the default value of java.io.tmpdir when starting Tomcat. My follow-up question then is, why is this done? Is it to be able to create a separate namespace for temp files generated by the Tomcat JVM process versus the other temp files on the file system?

Re: tomcat/unix security manager questions
Richard Smith wrote: Hi All, Just wondering if you could help me clarify a few questions I have about tomcat and catalina.policy. Im running tomcat 4.0.4 (w/ security manager) with mod_jk on solaris with about 300+ users, all of whom can deploy jsp/servlets from their public_html directory. I have never setup Tomcat to do this, but from reading the docs it looks like Tomcat instantiates a separate web application context for each user. A user requirement is that they must is to be able to read/write files in their home directory. This is what im a little confused about. I understand I can put an entry like: permission java.io.FilePermission /home/-, read,write,delete,execute; I would never grant the execute permission, this allows Tomcat to use Runtime.exec() to execute shell scripts, etc.! The above permission w/o execute should be fine. in catalina.policy, but how does this enable tomcat to write to other user's home directories (when tomcat is running as a user with minimal privledges)? Or must I change permissions on the file to allow the user that is running tomcat to write to it (is this the normal practice?). Yes, if you want to allow the user web applications to write and delete files in their own home directory Tomcat would need r/w file permissions. This can be done by adding the tomcat user tomcat to the group(s) which your users are members of. Then setup permissions on the public_html directory of mode 2775. Also, this is probably more a java question, but do standard unix permissions always take precedence over what is set in catalina.policy? (In my understanding the unix permissions take precedence, but I just wanted to make sure(please excuse my java ignorance)) Yes, unix file/dir ownership and permissions take precedence.

I currently recompile all my jsp's using jspc and update the

This is fine but not quite what I want. One of the problems is that my

no longer there when the file is precompiled. I have got
around this by
having a index.html that redirects after 0 secs to index.jsp.
Any solution to this?
I would like to be precompile so that all jsp go into

Common sense should tell you that posting snotty subject-lines will not help persuade list users to answer you. You seem to think that someone has an *obligation* to jump and answer you as soon as possible, but this is not the case. Be patient and polite and I'll bet someone responds.

Re: retrieving HttpSession in Filter? ServletResponse.setContentLength()?

ServletResponse.setContentLength()? hi craig. thanks for your reply. after digging deeper, i now know what's happening. it's quite strange. i'm calling tomcat from a (mobile) java client (not a web browser) and the client needs to know exactly how many bytes are being sent back to it by the server. when i call HttpServletResponse.setContentLength(##) in the servlet, the client receives the data without problem. however, my filter is doing post-processing on what the servlet wrote before sending the response back to the client. as such, i change my servlet code to *not* set the content length, and instead, the filter calls ServletResponse.setContentLength(##) before returning the response to the client. however, the client hangs for about a minute b/c it can't determine the length of the data being sent back from the server. so it seems that the problem lies in the filter when it calls ServletResponse.setContentLength(##). the problem doesn't happen with a normal web browser, as (i believe that) web browsers are able to somehow determine the size of the data being returned from the server (whereas the mobile java client that i'm working with isn't able to determine the size; thus the requirement to set the content length). do you have an idea of why this would be happening? If your filter is calling response.setContentLength() -- or any other header setting method, such as trying to add a cookie -- after the response has been committed, then this attempt to set the header will get ignored just like it would if your original servlet had done so. If you have a post-processing filter that can change the content length of the response, you are going to need to write a response wrapper that: * Buffers up the output from the servlet into either memory or a temporary file * After the real servlet completes, do whatever modifications are needed, calls setContentLength() on the real response, and then copies the modified output data to the real response. There was an example filter that did post-processing XSLT transformations on Java Developer Connection (at java.sun.com) a while back, which illustrated exactly this kind of processing. In fact, the original version of the code in the article had exactly this sort of bug, and had to be corrected later :-). thank you.

HttpServletRequest.getSession(false) works, but HttpServletRequest.getSession() *before* committing the response, resulted in a hang... is that behavior correct? There shouldn't ever be a hang, obviously. Are you sure you don't have any infinite loop in your wrappers somewhere (it's pretty easy to get that messed up)? There aren't any hangs in the standard Tomcat code for getSession().

Sorry, but you haven't included enough information for anyone to formulate an answer. Based on the information all I can say is that you have a null pointer exception.

servlet-jdbc-SQL server
Just taking some stumbling first steps talking to SQL server from a servlet using the Microsoft JDBC driver. Servlet container is tomcat 4.0.4. Quick question if I may: I need to insert a row into an SQL Server table and have the servlet generate a page that includes an automatically generated IDENTITY from the newly created row. How after the insert can I find the generated ID without conducting a subsequent query (which would have no guarantee of returning uniquely the newly inserted record)? // 'con' is a connection to MS-SQLserver with SelectMethod=cursor Statement state = con.createStatement( ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); // Generate an empty result set ResultSet content = state.executeQuery(sqlQuery); content.moveToInsertRow(); // Column 1 is id int IDENTITY NOT NULL PRIMARY KEY // Column 2 is name VARCHAR(20) content.updateString (2, something); content.insertRow(); // If I then query the inserted row, to find the newly generated // IDENTITY value I get MIN_INT instead of '1' (the default first // identity generated by SQL server if no seed is given) int id = content.getInt (1); Is this some peculiarity of the servlet interface to the driver, to the driver itself or just my bad undestanding of the insert process? Is it possible to configure the Statement so that the Insert row in the Result Set gets updated when the insert takes place and the 'id' gets generated? Please excuse the fact that this query starts to look more like a JDBC query than a tomcat query - not quite sure where the problem lies - tomcat+driver? driver? my understanding (most likely!). I am hoping that other servlet developers have crossed this bridge before. matt -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: servlet-jdbc-SQL server
With oracle there's a way to specify that a insert does a return, it's something like insert into tablea ( a ) values ( 'a' ) returning id. I know this isn't oracle that you're asking about, but you might try using that syntax on ms sql and see what happens. Or it might help to find it in their documentation (there's a guide oracle vs ms sql in the documentation). --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: Matt Brennan [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 8:36 AM To: [EMAIL PROTECTED] Subject: servlet-jdbc-SQL server Just taking some stumbling first steps talking to SQL server from a servlet using the Microsoft JDBC driver.

RE: more pool problems
Well, if it's not there than it has to be called from somewhere else. Hsql is apache's Java database I think and usually if you are using examples from Apache's site, they can tend to you HSQL in the examples. Try looking in your page, any pages that your page calls, web.xml and server.xml. I'd imagine it must be in there somewhere. -Original Message- From: Felipe Schnack [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 11:37 AM To: Tomcat Users List Subject: RE: more pool problems It's not there, i checked.

You might want to close your database connection, or at least return it to
the pool (I don't see you doing that, it ought to be after you close the
prepared statement).

RE: It would be great IF somebody answered me, ONCE, for change :(
Actually now that I think about it more that might be the cause of the null
pointer (but
probably not). In your poolman.xml file have you set the connection limit
to be a hard
limit? If you timeout on connections (user timeout) is fairly high you
could run out of
connections, and it might return a null instead of a connection.
But that's just a guess. Also, you might was to also turn on logging (debug
level) in
poolman as well so that you can watch the connections getting checked out
and in.

RE: servlet-jdbc-SQL server
As long as you run a second query to retrieve the @@IDENTITY value using the same connection handle, then you are guaranteed to receive the correct value. If you would like to verify that you are using the same connection handle, run the profiler application, and watch your app run. driver itself or just my bad undestanding of the insert process? Is it possible to configure the Statement so that the Insert row in the Result Set gets updated when the insert takes place and the 'id' gets generated? There are two ways of doing this. The first one is to use a stored procedure to do the insert/update and have it return the value. The second , and I haven't tried this would be to pass a compound statement insert into ...; select @@IDENTITY. I will give you one final warning about @@IDENTITY. If your statement invokes another statement (trigger, etc) that performs an insert into a table that contains an identity, you will receive the value of the last created identity, which probably is not the one you expect.

Mike,
Yes I am returning the connection to the pool after
closing the ps. As you can see in the jsp code that I
have attached earlier to Craig, I am closing the
preparedstatement then returning the instance. Here
again the snippet.

ps.close();
thisManager.returnConnection(myConn);

Re: get blank pages when using precompiled JSPs (jspc problem?)

I've traced my precompiled JSPs not responding problem down to the following
statement returning null:
_jspxFactory = JspFactory.getDefaultFactory();
Since this a boiler plate jsp statement that does work when the JSPs are
dynamically
compiled, it seems to me that there is a problem in my runtime environment
that is
preventing the default factory from being set when the JSPs are statically
compiled.
Any suggestions as to what could be causing this problem would be greatly
appreciated.

Hello Tomcaters:
can anyone tell me why a JSP that works when dynamically compiled

the jsp class file is generated via the ant task listed below and packaged
into a .war file. everything appears to build okay and yet when i hit the
page nothing is returned. i know that the class file is hit because the
return status is 200 and i see my debug statements

the only differences between the statically and dynamically generated files
are the packages, e.g. org.apache.jsp vs. com.secretseal and the class
name, e.g. foobar vs foobar$jsp. i suspect that the problem has to do with
different runtime support for the two versions, e.g. for some reason the text
generated by the statically compiled version is being directed to the bit
bucket.
suggestions as to how to resolve this problem are greatly appreciated.

OFF-TOPIC: Pointers to CallableStatement docs?
Hello - I think there is a java-user list, or even a jdbc-interest list, but I'd rather not subscribe when all I need is one quick pointer, so I am hoping someone on this list can get me started. I'm having quite a bit of difficulty working with stored procedures in my classes and servlets. The database is MS SQL Server 2000. I've read every single doc I can find, both at Sun, through Google, and even through the driver vendor's documentation. I even scammed some code from a JDBC 3.0 book (the only one I could find) at Border's, with still no luck. Can anyone point me to a resource that explains how to setup stored procedures in a CallableStatement correctly? I understand about registering the output parameters and setting the input types, and I understand that the parameters in a CallableStatement are numbered from left to right starting at 1. I've seen the examples at Sun, etc. but they're not much help. The problem is that all of the examples I can find deal with very simple, very rudimentary stored procedures, like finding the average of two numbers, or whatever. Our stored procedures are more involved than that. Example: a stored procedure used to validate logins. It has 5 input parameters, and 5 output parameters. It returns a status. According to the docs I have read so far, that means I should have a CallableStatement with 11 question marks (?) in it (5 + 5 + 1 = 11). but that doesn't work, and I have tried every combination of inputs, outputs, input/outputs, etc. that I can think of, to no avail. Any help or pointers to resources that explain stored procedures and CallableStatements in more in-depth fashion would be greatly appreciated. - John John Turner [EMAIL PROTECTED] | 248-488-3466 Advertising Audit Service http://www.aas.com -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: retrieving HttpSession in Filter? ServletResponse.setContentLength()?
hi charlies and craig. thanks for your replies. At 08:21 02/08/19 -0700, you wrote: If your filter is calling response.setContentLength() -- or any other header setting method, such as trying to add a cookie -- after the response has been committed, then this attempt to set the header will get ignored just like it would if your original servlet had done so. If you have a post-processing filter that can change the content length of the response, you are going to need to write a response wrapper that: * Buffers up the output from the servlet into either memory or a temporary file * After the real servlet completes, do whatever modifications are needed, calls setContentLength() on the real response, and then copies the modified output data to the real response. the latter (ResponseWrapper) is exactly what i am using. basically, the same thing as the CharResponseWrapper described in: http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Servlets8.html#82361 i tried calling response.setContentLength() on the *real* response in my filter *before* the response is sent to the (mobile) java client, but the client isn't detecting that the content length has been set and hangs waiting. however, when i set the content length in the servlet and not the filter, the client detects the content length (although the length doesn't account for the extra data needed to be added in the filter)... right after calling setContentLength on the real response in my filter, is there any way to call something like getContentLength() on the response to confirm that it's being set? There was an example filter that did post-processing XSLT transformations on Java Developer Connection (at java.sun.com) a while back, which illustrated exactly this kind of processing. In fact, the original version of the code in the article had exactly this sort of bug, and had to be corrected later :-). do you happen to have the link to the article? i followed sun's example filter using a CharResponseWrapper and my filter's not working... :| thanks again for helping. i appreciate it. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: OFF-TOPIC: Pointers to CallableStatement docs?
When you say it returns a status, do you mean it is a function (I work
primarily with Oracle, so if this does not apply to MS I apologize)?
If so, you need to make the call something like:
CallableStatement stmt = conn.prepareCall({call ? = proc(?,?, ... )});

Subject: OFF-TOPIC: Pointers to CallableStatement docs?
Hello -
I think there is a java-user list, or even a jdbc-interest list, but I'd
rather not subscribe when all I need is one quick pointer, so I am hoping
someone on this list can get me started.
I'm having quite a bit of difficulty working with stored procedures in my
classes and servlets. The database is MS SQL Server 2000. I've read every
single doc I can find, both at Sun, through Google, and even through the
driver vendor's documentation. I even scammed some code from a JDBC 3.0
book (the only one I could find) at Border's, with still no luck.
Can anyone point me to a resource that explains how to setup stored
procedures in a CallableStatement correctly? I understand about registering
the output parameters and setting the input types, and I understand that the
parameters in a CallableStatement are numbered from left to right starting
at 1. I've seen the examples at Sun, etc. but they're not much help.
The problem is that all of the examples I can find deal with very simple,
very rudimentary stored procedures, like finding the average of two numbers,
or whatever. Our stored procedures are more involved than that.
Example: a stored procedure used to validate logins. It has 5 input
parameters, and 5 output parameters. It returns a status. According to the
docs I have read so far, that means I should have a CallableStatement with
11 question marks (?) in it (5 + 5 + 1 = 11). but that doesn't work, and
I have tried every combination of inputs, outputs, input/outputs, etc. that
I can think of, to no avail.
Any help or pointers to resources that explain stored procedures and
CallableStatements in more in-depth fashion would be greatly appreciated.

Re: Using Tomcat as a proxy?
Why would you want to use a Java Servlet Container to do proxying? It's like using a Space Shuttle to do door-to-door delivery. If you need proxying, use Squid or Apache. The reason I have to do this is to make the best of a rather brain dead product deployment. This is not a long term fix but it is only a temporary fix to keep customers happy for two months until we can change everything. I got thrown into the whole mix after the fact. Unfortunately installing Apache or Squid (my first suggestion) on the clients site is not an option. If you want to have pieces of other sites inside your webapp, the it is a whole new ball game. Ultimately this is the idea. Basically we need to use our webapp to get a page from another server and pass it back to the user but make it appear that it came from our webapp. It is an ugly thing to do but I need to find a quick fix before I can work on a real fix. If you have any ideas, suggestions or links I would appreciate it. __ Do You Yahoo!?

Tomcat 3.3 does not find jndi.properties
Hi, my Tomcat 3.3a does not find the jndi.properties file regardless of where I put it inside the web application tree. That is, I tried the web app root as well as WEB-INF/lib and WEB-INF/classes. Only if I place it directly into jre/lib the file is found, which of course is not really an option for a modular application. Does anyone know any help or maybe a workaround? A little research yielded only that this symptom was encoutered with Tomcat 3.2.x, being a bug in the AdaptiveClassLoader -- which does not seem to exist any more as of Tomcat 3.3 it seems.

RE: OFF-TOPIC: Pointers to CallableStatement docs?
Right. My setup looks like this:
cstmt = sConn.prepareCall({? = call
sp_validate_pwd(?,?,?,?,?,?,?,?,?,?)});
Basically, there are 5 inputs (username, password, IP address, browser type,
and referer) and I'm supposed to get a return status back (bad or good) and
5 outputs: 3 booleans and 2 strings (isValid, isExceeded, isEnabled, name,
and title).
I've tried everything I can think of...only having 6 question marks, having
all 11, only using 5, etc. to no avail. I enabled debug logging on the
driver, and I get messages that say parameter my_parameter not registers as
output or not registered as input, even when they are, and regardless of
how I use the set*() and registerOutParameter() methods. Very confusing.
I'd love to find a complete stored procedures How-To somewhere that
addresses complex stored procedures instead of the basic tutorials that do
simple math or just insert a row.
Thanks for the reply.

When you say it returns a status, do you mean it is a function (I work
primarily with Oracle, so if this does not apply to MS I apologize)?
If so, you need to make the call something like:
CallableStatement stmt = conn.prepareCall({call ? = proc(?,?, ... )});

Subject: OFF-TOPIC: Pointers to CallableStatement docs?
Hello -
I think there is a java-user list, or even a jdbc-interest list, but I'd
rather not subscribe when all I need is one quick pointer, so I am hoping
someone on this list can get me started.
I'm having quite a bit of difficulty working with stored procedures in my
classes and servlets. The database is MS SQL Server 2000. I've read every
single doc I can find, both at Sun, through Google, and even through the
driver vendor's documentation. I even scammed some code from a JDBC 3.0
book (the only one I could find) at Border's, with still no luck.
Can anyone point me to a resource that explains how to setup stored
procedures in a CallableStatement correctly? I understand about registering
the output parameters and setting the input types, and I understand that the
parameters in a CallableStatement are numbered from left to right starting
at 1. I've seen the examples at Sun, etc. but they're not much help.
The problem is that all of the examples I can find deal with very simple,
very rudimentary stored procedures, like finding the average of two numbers,
or whatever. Our stored procedures are more involved than that.
Example: a stored procedure used to validate logins. It has 5 input
parameters, and 5 output parameters. It returns a status. According to the
docs I have read so far, that means I should have a CallableStatement with
11 question marks (?) in it (5 + 5 + 1 = 11). but that doesn't work, and
I have tried every combination of inputs, outputs, input/outputs, etc. that
I can think of, to no avail.
Any help or pointers to resources that explain stored procedures and
CallableStatements in more in-depth fashion would be greatly appreciated.

Craig, PoolMan, latest version WAS the problem.
Ok. I reverted to an older version of PoolMan, where we use pool.prop instead of pool.xml. That version works fine. I have not hit the exception although I tested it for sometime.

Realm Authentication Across Multiple Servers
The application we are working on is laid out on the network like so (* means many): Apache2 jk2_mod Tomcat4 Web Site Servers* internal network mapping Tomcat4 File Servers* Basically the application acts much like sourceforge or another download site, but I would like to carry authentication from the Web site server to the request made to the File Servers. Is this possible? I did think about a way of creating a timed/digested certificate that could be passed in the request string, but it would be ideal to have the Principal be used on all servers. The user roles for the Web site servers are pulled from a DB, but I have heard that these servers can share a JNDI context, so couldn't information be put in there? Any advice would be appreciated as I'm working in rational rose this afternoon trying to lay things out :-) -Jacob --- Outgoing mail is certified Virus Free.

Design question
Greetings everybody, I am doing some research on possibility of using Tomcat to do a project. General requirements as follows 1. A user will login to the web application and upload a file to a remote server. He or she can only access his or her WIN2K/NT domain to upload this file. 2. User will download a file or a number of files from the remote server - again from his or her domain. I was told that I can do this job using Java Servlet and IBM Websphere or BEA Weblogic. I am not sure if this is possible in Tomcat. Has anybody done similar work using Tomcat. Can you share your experiences please?

Re: AW: got javax.servlet.UnavailableException when setting unpackWar to false
Hello Juri, Well, don't use File io in a servlet application unless you are reading/writing to a place guaranteed to be read/writable such as each context's temp dir made available by any server implementing the Servlet 2.3 spec. To read a config file in a servlet portable way, do the following: InputStream is = getServletContext().getResourceAsStream(/WEB-INF/testApp.properties); That will read the testApp.properties file in the current context's WEB-INF directory whether the context is being served out of a directory on the filesystem or out of a .war archive. You can also try this, if your testApp.properties is in the path of one of the available classloaders: InputStream stream = Thread.currentThread().getContextClassLoader().getResourceAsStream(myApp.pr operties); Or use the following if your properties file is in the same relative location as the class that is loading it. InputStream propsStream = this.getClass().getResourceAsStream(testApp.properties); or like this if you put the testApp.properties in the root of the current classloader (meaning WEB-INF/classes): InputStream propsStream = this.getClass().getResourceAsStream(/testApp.properties); There you go. Lots of possibilities. Jake Monday, August 19, 2002, 6:41:07 AM, you wrote: JF solved it by myself...

Hello - I think there is a java-user list, or even a jdbc-interest list, but I'd rather not subscribe when all I need is one quick pointer, so I am hoping someone on this list can get me started. I'm having quite a bit of difficulty working with stored procedures in my classes and servlets. The database is MS SQL Server 2000. I've read every single doc I can find, both at Sun, through Google, and even through the driver vendor's documentation. I even scammed some code from a JDBC 3.0 book (the only one I could find) at Border's, with still no luck. Can anyone point me to a resource that explains how to setup stored procedures in a CallableStatement correctly? I understand about registering the output parameters and setting the input types, and I understand that the parameters in a CallableStatement are numbered from left to right starting at 1. I've seen the examples at Sun, etc. but they're not much help. The problem is that all of the examples I can find deal with very simple, very rudimentary stored procedures, like finding the average of two numbers, or whatever. Our stored procedures are more involved than that. Example: a stored procedure used to validate logins. It has 5 input parameters, and 5 output parameters. It returns a status. According to the docs I have read so far, that means I should have a CallableStatement with 11 question marks (?) in it (5 + 5 + 1 = 11). but that doesn't work, and I have tried every combination of inputs, outputs, input/outputs, etc. that I can think of, to no avail. Any help or pointers to resources that explain stored procedures and CallableStatements in more in-depth fashion would be greatly appreciated. - John John Turner [EMAIL PROTECTED] | 248-488-3466 Advertising Audit Service http://www.aas.com -- 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] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Craig, PoolMan, latest version WAS the problem.
Did you try using a soft limit? That combined with a larger scavenge count and a shorter time limit on the connections (not the user time limit) should allow you to scale decently. Also you really should check the connection to be sure that it's not a null connection prior to using it. That should also elminate the problem, but you'd have to add some code to handle when it's not there (retry acquiring a connection most likely). --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: Luminous Heart [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 9:54 AM To: Tomcat Users List Subject: Craig, PoolMan, latest version WAS the problem.

RE: It would be great IF somebody answered me, ONCE, for change :(
It can, and then you'd have other problems. I use oracle here and
even though I'm licensed for x connections the database hasn't
yet failed to give me a connection at high load times. I've got
my scavenge count fairly high with only a 2 minute timeout on the
connections in the pool (user timeout is more). Seems to work
pretty well for me. Much better than that connection pool that I
wrote.

I will test with this, although I tried to

hey, can i get a copy of the debugger? or do others have any debugger suggestions? tomcat error messages are pretty cryptic to me still, though for the simple JSP work i do i get around it most of the time. but perhaps a debugger will save me some hair pulling. -- carrie s.

Re: Tomcat 4.0.4: Unnecessary $TOMCAT/temp/ directory?
Thanks for your feedback, Craig and Glenn. Craig, I think you're confusing $CATALINA_BASE/temp/ with $CATALINA_BASE/work/. StandardContext implements the temporary working directory for each context (per the servlet spec) in postWorkDirectory(). It creates a separate temp space per context within the work subdirectory. That said, how does $CATALINA_BASE/temp/ fit into the picture? I can understand the benefit of overriding the java.io.tmpdir system property is to forcing a separate temp path for the Tomcat JVM process as a whole (note: not the per-context work/ directory), which would isolate the temporary files generated/accessed in the process from the rest of the temp files in the file system. Is there any other reason specific to Tomcat? (As an aside, if you are truly concerned about security and run Tomcat with a Java2 security policy, you probably wouldn't want to give any file permissions to webapps outside their respective docbase root and work directory anyway.)

Thanks Glenn. The following Java API link has a quick blurb about the java.io.tmpdir system property: http://java.sun.com/j2se/1.3/docs/api/java/io/File.html#createTempFile(java.lang.String, java.lang.String, java.io.File) The JDK sets the default value for this property to be /tmp on Unix and c:\temp on Windows. So, it does not seem necessary to override the default value of java.io.tmpdir when starting Tomcat. My follow-up question then is, why is this done? Is it to be able to create a separate namespace for temp files generated by the Tomcat JVM process versus the other temp files on the file system? The servlet spec requires that each web application receive a servlet context attribute named javax.servlet.context.tempdir that is a java.io.File object to a temporary storage directory. It is therefore not reasonable to use the value specified by the java.io.tmpdir system property, because that is global to the entire JVM. See section 3.7.1 of the Servlet 2.3 spec: http://java.sun.com/products/servlet/download.html The $CATALINA_HOME/temp directory hierarchy is how Tomcat implements this spec requirement. And you should be glad -- otherwise the servlet generated for your index.jsp page (which is put in the per-context temporary directory under a name specified by the JSP apge compiler) would be stomped on by the servlet for some other webapp's index.jsp page. Thanks in advance, Eddie Craig --- Glenn Nielsen [EMAIL PROTECTED] wrote: Do not remove this temp directory. This is the temporary directory configured in the Tomcat startup with -Djava.io.tmpdir.

According to the source, if the workDir attribute of StandardHost is null (default case), the temp dir will be generated inside $CATALINA_BASE/work/.

RE: Design question
The token is the validation. It's a way of passing around that the user has been validated. Consider it to be a relay race, there's a baton that you're passing around. If you have the baton than you're a valid runner in the race. A security token is like the baton, if your user can present the token, and it's valid then they're ok to deal with. This of course has some issues, but it's one way of doing it. --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: Louis Voo [mailto:[EMAIL PROTECTED]] Sent: Monday, August 19, 2002 10:26 AM To: Tomcat Users List Subject: Re: Design question Can you tell me after validate how you redirect to another site?

RE: Design question
Hi, For this problem I would say it would be best to use IIS and Tomcat combo Because IIS can authenticate users by using NTLM authentication scheme. 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.
