Re: jsp and tomcat 4
You need to make changes to a jsp file, not java file. Tomcat will detect changes automatically and will translate jsps into java files and then compile them. --- Oskar Marco Magistrali wrote: Hi, I have a question: if I modify a JSP under tomcat4 i don't see any change in browser because tomcat4 get the .class of JSP in cache (directory work) How can I say to recompile the jsp if there are changes in java?? tanks Marco
Re: Precompiled JSPs
Hi Uri, You have to compile your JSPs with -webxml and -webapp options. This option will create a web.xml file with all the required servlet mapping and everything will work fine. I ran such command: jspc.sh -p package name -dd directory there to output translate java files -webxml path where to store a web.xml file (i.e. /temp/web.xml) -webapp directory of your webapp where all the JSPs reside After the web.xml file is produced you have incorporate it with your tomcat original web.xml file. Or you could create a servlet mapping for your jsps manually. In the following way: servlet servlet-namecom.somecompany.pacakge.SomeJsp/servlet-name servlet-classcom.somecompany.pacakge.SomeJsp/servlet-class servlet . . you need to put all servlet tags first (for each jsp) . then servlet-mapping tags go (for each jsp) . servlet-mapping servlet-namecom.somecompany.pacakge.SomeJsp/servlet-name url-pattern/SomeJsp.jsp/url-pattern /servlet-mapping This way you do not need to change urls in your original JSPs to class names, you can just use the same urls in your JSPs and pre-compiled JSPs. Hope this helps, Oskar Uri Cohen wrote: I precompiled all my JSPs in the application, using jspc. Most pages work OK, but there are some pages which don't. For some reason, when loading these pages the session is lost, causing many errors. I solved the problem by sending the request parameter JSESSIONID when calling these pages. These pages worked fine as regular JSPs, and this symptom only occures when I use them as servlets. Has anyone encountered such a problem?
Re: jspc and deployment
Thanks. I got it to work. Oskar Sophie wrote: Hi Oskar, I am using the options: -uriroot /$TOMCAT_HOME/webapps/AppName -d /$TOMCAT_HOME/webapps/AppName/WEB-INF/classes to set the directory where the results of jspc should be placed -webxml/OWN_DIR/webAppName.xml -webapp/$TOMCAT_HOME/webapps/AppName to specify the directory that contains the jsp's I remove the jsp's after running jspc from /$TOMCAT_HOME/webapps/AppName. After running jspc, you should run javac to compile the generated java-files to class files. I update my own web.xml with the results of /$OWN_DIR/webAppName.xml, and then everything runs fine.

get/setAttribute and getParameter...
Hi,
What is more time consuming?
JSP1:
% request.setAttribute(FLAG, new Boolean(true)); %
jsp:include page=JSP2.jsp flush=true/
JSP2:
% boolean FLAG = ((Boolean)
request.getAttribute(FLAG)).booleanValue();
if (FLAG) {
..
...
}
%
OR?:
JSP1:
jsp:include page=JSP2.jsp?FLAG=true flush=true/
JSP2:
% String FLAG = request.getParameter(FLAG);
if (FLAG.equals('true)) {
..
..
}
%
OR?:
JSP1:
jsp:include page=JSP2.jsp?FLAG=true flush=true/
JSP2:
% boolean FLAG = (new
Boolean(request.getParameter(FLAG))).booleanValue();
if (FLAG) {
..
..
}
%
AND, which way is it best practiced.
Thankss for any help!

jsp:include page=%=servletPath% flush=true|false/ errors
Hey, guys,
I am new to tomcat... using Tomcat v4.0-b3/b5.
I am trying to include other jsps output in one main jsp and getting an
IllegalStateException: with error message:
Cannot forward after response has been committed.
This is what I am doing:
% for(int i = 0; i typeNames.length; i++) {
url = my url is constructed here; %
jsp:include page=%=url% flush=true // if I set the
flush to false I see the first iterated page of the servlet that I am
including, if I am setting it to true then I get exception right on the
first iteration of the loop.
% } %
I am writing JSPs then I am compiling them into servlets by using
jspc.sh script that uses JspC.java in jasper's package. So when I go
into the browser I am accessing not JSPs but converted jsps to Servlets
which were generated by this script. (jspc.sh).
I have tried many different things already, setting isThreadSafe to
FALSE, setting buffer to a very big size, setting autoFlush to TRUE and
FALSE, nothing seems to work.
Has anyone ever encountered such problems?
Thanks for your help,
Oskar
