precompile question
Hi All - When pre-compiling using an ant task, is there a way to exclude certain files from being precompiled? I tried using an exclude tag on the jasper2 task, but it tells me that it does not support that. It looks like the deprecated jspc task that used to come with apache support include/exclude filters... If I put the exclude on the javac part of the precompile, then the file does not get compiled, but it is still included in the generated web.xml file, and makes it so tomcat throws an error, so that doesn't help. If there is a way to implicitly include all the files that need compiling, I would be willing to settle for that as well.

Re: precompile question
Thanks for the info. I'll just have ant move the files to a temporary extension before the jasper2 task, then back to .jsp when it is done. Thanks, Matt Tim Funk wrote: No, there are no way to exclude files. If you have a file which has an extension of jsp, then consider it to be a jsp. If its not a jsp - it should be a different file extension. (For example .jspf for a jsp fragment - files with an extention of .jspf are excluded) -Tim Matt Bathje wrote: Hi All - When pre-compiling using an ant task, is there a way to exclude certain files from being precompiled?

Does tomcat cache compiled JSPs?
Hey everybody - I am trying to get Tomcat to dynamically compile JSPs that are uploaded through a web interface. I am using the org.apache.jasper.JspC ant task trough code to do it. After a bit of work, I am able to get the file parsed and compiled into the proper directory, which as far as I know is: TOMCAT_HOME/work/Catalina/mysite/org/apache/jsp/WEB_INF/tiles/public/layouts/ (I got this based on the fact that if I update the .jsp file by hand and wait for the scheduled jasper compile, the file in this directory gets updated.) Both the .class and the .java files are updated with a time stamp of right around when the upload occurred, and if I view source on the .java file, it contains whatever change I uploaded into the .jsp file, so everything seems like it should work. When browsing the site though, the updated version of the file is not used. If I restart the site (either through manager stop/start or reload, or through restarting tomcat) the new file is then used. Waiting for the scheduled jasper compile does NOT recompile the file (as would be expected I think...) If I change the .jsp file by hand after my upload/compile process, and wait for the scheduled jasper compile, the hand-updated version of the file is used. It seems as though I am missing something when I do my compile. I looked through the JspC (and related) code, and it seems as though if any files were changed, it reloads the JSPServlet, and this somehow makes the updated files be used. So - I guess the questions I have are: - Does tomcat cache the compiled JSPs somewhere? - If so, how to reload that cache? - Does that fact that the newly-compiled file is always called from a jsp:include page=xxx.jsp / make a difference? - Is there a way to use the running jsp compiler instead of using the JspC ant task - I think using the JSPServlet would solve all my problems actually, but I see no way to call it from my code. Thanks, Matt PS - I am 99.% sure that this is not a browser/proxy caching issue. It happens on multiple browsers/computers, and I see no other caching issues on the site when changes are made, this is the only time/place. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Does tomcat cache compiled JSPs?
is the jsp doing the %@ include being jsp:include-ed itself into
another jsp?
It isn't being included, but it is being called as part of a
struts/tiles definition.
also, are you using tomcat 5? if you are i believe you can use EL to
do something like:
%@ include file=${your_object.dynamic_file_name} %
Doesn't seem to work:
2005-01-13 12:22:56 StandardContext[]Background compile failed
org.apache.jasper.JasperException:
/WEB-INF/tiles/public/layouts/index.jsp(54,0) File
/WEB-INF/tiles/public/layouts/${pathToInclude} not found
I didn't see anything in the JSP documentation that would indicate you
can use EL in the include directive myself.

Re: dynamically compile JSPs
So it looks like I need to send in classpath and destination directory configuration stuff to the JspC task (using setClassPath and setOutputDir on antTask I think) Where do I get the proper information from though? (The proper information to me means the same classpath and output directory that tomcats jasper servlet uses) Is there a way to read the jasper servlets configuration variables in my serlvet? Of can I figure it out from the JspC(and related) source code? I haven't seen anything helpful there yet. Hey all - replying to myself yet again. I got this working now, it parses and compiles the JSP file to the proper directory under TOMCAT_HOME/work/ Now - I have another problem - there are 2 types of files that I do this with. They both wind up being Struts/Tiles layout files, just in different directories basically. When I upload/compile to one of the directories, it works perfectly for me - the JSP file is parsed and compiled, and when I view the pages the changes are properly reflected. In the other directory, it parses/compiles the uploaded JSP page, but for some reason Tomcat never displays the updated JSP page until I restart the server. There is nothing special about this directory that I know of, it is just the parent directory of the one that is actually working. Any idea how to fix that little problem? I was looking through the JspC code, and it looks like it reloads the JSP Servlet after a compile is done -but I'm not sure that would fix my problem (and as far as I know, there is no way to set JSPServletWrapper.reload to true from my serlvet.) Any ideas on this last problem would be greatly appreciated. Thanks, Matt - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: dynamically compile JSPs
I was messing around with the code a little bit, and tried this:
JspC antTask = new JspC();
antTask.setArgs(new String[] { -compile, uploadTileFilePath });
antTask.execute();
but this always gave me an error that javax.servlet package could not be
found.
Replying to myself here - but I got a bit further with this and need
more support if anybody has any ideas.
I thought at first that this code would parse/compile the uploaded JSP
page using the same paths/classpath/etc. that the Jasper servlet setup
in web.xml uses.
It turns out I am wrong and it seems like it is using some sort of
default for the classpath and output directory.
The classpath just has the classes from the jars for my local site
(hence no tomcat jars and there error being seen above.
It is outputting the jsp file to a .java file under
TOMCAT_HOME\org\apache\jsp\WEB_INF\tiles\public_\file_jsp.java (and
presumably if I could get compilation to work it would compile to that
directory as well.)
So it looks like I need to send in classpath and destination directory
configuration stuff to the JspC task (using setClassPath and
setOutputDir on antTask I think)
Where do I get the proper information from though? (The proper
information to me means the same classpath and output directory that
tomcats jasper servlet uses) Is there a way to read the jasper servlets
configuration variables in my serlvet? Of can I figure it out from the
JspC(and related) source code? I haven't seen anything helpful there yet.

Usage of the JspC class. This should be what you want.
I work in Windows 95% of the time, and I'm a simplicity freak, so I tend do do
things, most of the time, with batch files called from UltraEdit. Anyway, this
is relevant because one of the steps in my typical build process is a
compilation of all JSP's. I use this class to do that. I can give you the two
lines from my batch file that does this if it would be helpful, but I tend to
think the javadocs will get you where you want to go.
This is kind of an old thread I'm replying to - but I implemented what I
thought would work for this, and haven't been able to get anything
working reliably. As a refresher, the scenario is this:
- a Tomcat 5.0.x server with Jasper setup in development=false mode
- I upload a jsp page through a web interface, and want it to be
compiled/usable immediately, instead of waiting for the scheduled jasper
compilation
- putting ?jsp_compile=true on the page doesn't seem to work
- making development=true isn't an option
After looking through the JspC documentation a little bit, I tried this
code in my class after the JSP file is uploaded:
JspC antTask = new JspC();
antTask.setArgs(new String[] { uploadTileFilePath });
antTask.execute();
And this does not seem to compile the file reliably. It does seem like
something is happening, because the upload/compile action takes about
25-30 seconds longer to load when the jsp compilation code is included.
In my work directory, the .java and .class files are never updated (new
time stamp) right away.
Sometimes if I wait a bit (5-10 minutes) the files are updated properly,
but this seems to be the normal scheduled compilation.
Sometimes if I load the page up in a browser after it has been
uploaded/compiled, it seems to be compiled on access, but this does
not always happen.
I was messing around with the code a little bit, and tried this:
JspC antTask = new JspC();
antTask.setArgs(new String[] { -compile, uploadTileFilePath });
antTask.execute();
but this always gave me an error that javax.servlet package could not be
found.
I then tried:
JspC antTask = new JspC();
antTask.setArgs(new String[] { uploadTileFilePath });
antTask.execute();
antTask.setArgs(new String[] { -compile, uploadTileFilePath });
antTask.execute();
and this seemed to make it (so far) that the JSP page always gets
compiled the next time it is loaded in a browser.
This is passable if it must be the solution, but what I would really
like is that the file gets completely compiled during the upload/compile
action. The reason for this is that I want the person uploading to have
to deal with the extra processing time, and not the person loading the page.
Any help with solving this problem would be greatly appreciated.
Thanks,
Matt

dynamically compile JSPs
Hi all - If you have your tomcat servers setup with development=false (compiling every 5 minutes) - is there a way to dynamically compile certain JSP pages from inside your servlet code?

Re: Tomcat, Apache connected in interesting way
Joshua Szmajda wrote: Hi all, I run a pretty high traffic site using Tomcat. We've gone through a number of configurations in the past, and I wanted to share with you the newest setup that we're using. It's a bit unorthodox perhaps, and I was wondering if anyone could think of possible problems? It does seem to be the fastest and most stable setup we've had yet. Previously we've used Apache and Tomcat connected through jk1 and jk2. Also we've run direct to tomcat's http connector. JK1 was ok, but very slow. JK2 was fast (using unixSocket communication), but very buggy and crash prone. Tomcat alone was good, but it lacked some advanced apache stuff we wanted (Mostly URL Rewriting and good SSL handling). After reading about the upcoming mod_proxy ajp connector for apache 2.2, I had the idea to use stuff that's in the current RHEL apache 2.0 release to accomplish what I feel to be a similar effect. We've set up apache to reverse proxy requests for .jsp and .do (we're using struts) to tomcat's standard http connector. From the httpd.conf: Proxy * Order deny,allow Allow from all /Proxy ProxyRequests off RewriteEngine on RewriteRule ^/$ http://128.121.26.205/index.jsp [P,NC] RewriteRule ^/(.*.jsp.*)$ http://128.121.26.205/$1 [P,NC] RewriteRule ^/(.*.do.*)$ http://128.121.26.205/$1 [P,NC] This allows apache to process additional rewriting things (I left them out) and also to serve images and other static content. I felt that apache would be better at handling static content than tomcat in general, so this will be an overall speed improvement. Anyway, any flaws here I should be aware of? Comments? Thanks! Joshua - Are tomcat and apache running on the same server? If so, it appears from what you have here that they are on the same port...so...what am I missing?

ROOT context using admin webapp
I sent this a wihle back and didn't get a response, so I'm going to try again. This applies to both Tomcat 5.0.25 and 5.0.27. Is it possible to add a ROOT context to a host using the administrative webapp? I know how to do it by editing the server.xml (or Catalina/host/context.xml) file, but with the admin webapp I can't get a valid ROOT context added. If I try to add the ROOT context with a blank path (). I get an error that the path must start with a slash (/). If I try to add the ROOT context with a single slash (/), all links and stylesheet/javascript includes contain a slash at the front of them, which causes many problems. When I look at the context.xml file, it seems as though the path gets written to the file as / instead of as as it should be for a ROOT context. I looked through bugzilla, and found this issue: http://issues.apache.org/bugzilla/show_bug.cgi?id=26399 The closing comment is very confusing to me though. It says that management tools will refer to ROOT contexts as /. It also says that internally (and the xml config files count as internal) ROOT contexts will be referred to as . He concludes by saying this is not a bug anyway Now to me this seems like a bug - I am attempting to add a ROOT context using /, and it gets added in server.xml as / instead of as . I'm hoping that I am just doing something wrong and there is no bug - so, does anybody know how to add a ROOT context to a host using the administrative webapp?

java server mode vs. client mode
I posted this on the struts list this morning, but it might get better answers here. I was reading the stories here: http://www.sys-con.com/story/?storyid=45250 http://www.kano.net/javabench/ Summary: Java in server mode is faster than C++ in the benchmarks run. Java in client mode is much more iffy, sometimes faster, sometimes slower, and sometimes the same. So my question becomes - does anybody have any experience running their Tomcat jvm using the -server option instead of letting it default to client? Based on what the tester says, the only downside of running the jvm in server mode is a longer startup time, but the Java code still beat C++ even with the longer times, so it can't be too bad. So anybody have any experience/thoughts on this? Thanks, Matt Bathje - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I was sure it was something that has been mentioned on the list before, but I wasn't able to find a way to search for it that yielded good results. Thanks again for the info!

Java in client mode is much more iffy, sometimes faster, sometimes slower, and sometimes the same. So my question becomes - does anybody have any experience running their Tomcat jvm using the -server option instead of letting it default to client? Based on what the tester says, the only downside of running the jvm in server mode is a longer startup time, but the Java code still beat C++ even with the longer times, so it can't be too bad.

[OT] Re: java server mode vs. client mode
Yes, I understand that it may not be completley accurate, but I was less interested in the Java/C++ comparison than the client/server mode comparison.

I haven't been through the benchmark code throroughly, but there's definitely a bias somewhere. --- Eric VERGNAUD - JLynx Software Cutting-edge technologies and services for software companies web: http://www.jlynx.com --- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
