Precompilation of JSPs

Hi all....
          we have a problem regarding the precompilation of the JSP pages. In
          development mode we don't want the jsps top get precompiled when the
          Server is restarted or app is redeployed as it takes a lot of time to
          see a minor change working.
          For this we have modified our weblogic.xml file in the WAR
          descriptors as:
          <jsp-descriptor>
          <jsp-param>
          <param-name>precompile</param-name>
          <param-value>false</param-value>
          </jsp-param>
          </jsp-descriptor>
          but for some reason it does not seem to work..
          any pointers to correct it...????
          thanx
          aseem

I never found a fix for this.
          In the end I just wrote an ant script using basic ant tasks i.e. no weblogic ant tasks - and used the weblogic.xml file to get the server to precompile jsps at deploy time.
          My experience with the weblogic ant tasks has been less than satisfactory.
          Good luck - and let me know if you have any major breakthroughs.

Ramesh,
          We experienced this sympton as well. In our JSPs, we converted
          <%@ include file="xyz.jsp"%> (static include, source time) to
          <jsp:include page="licensedQuote.jsp"/> (dynamic include, run time)
          and the problem went away.
          We still use static includes at the very start of the JSPs. It seems the problem only occurs when the static include is inside of a tag whose body does JSP evaluation.

          POR FAVOR, LEIA COM BASTANTE ATENÃ‡ÃƒO, VALE A PENA!
          COMO TRANSFORMAR 6 (SEIS) REAIS EM NO MINIMO 6.000(SEIS MIL REAIS) !! : VOCÃŠ Ã‰ CAPAZ, APENAS FAÃ‡A FUNCIONAR.!
          Eu achei uma mensagem sobre esse assunto e nÃ£o dei muita atenÃ§Ã£o por ser um texto muito longo e parecer ser presente de papai Noel, mÃ¡s resolvi arriscar e deu certo. Vou tentar resumir para que vc tbm nÃ£o ache esse texto cansativo e se quiser mais informÃ§Ãµes mande-me um e-mail â€“ [email protected].
          Funciona assim:
          PASSO 1: Separe 6 meias folhas de papel e escreva em cada uma, o seguinte bilhete: " POR FAVOR, PONHA-ME EM SUA LISTA DE REMETENTES" colocando seu nome e endereÃ§o logo abaixo. Agora adquira 6 notas de R$ 1,00 e envolva cada uma em um dos bilhetes que vocÃª acabou de escrever. Em seguida, envolva cada um deles novamente com um papel escuro, para evitar que alguÃ©m veja a nota e viole o envelope, roubando o dinheiro. EntÃ£o coloque cada um dentro de um envelope e lacre. A lista abaixo contÃ©m 6 nomes com endereÃ§os e vocÃª tem 6 envelopes lacrados. VocÃª deve REMETER PELO CORREIO, um envelope para cada um dos nomes da lista. FaÃ§a isto, anotando corretamente o nome e o endereÃ§o nos envelopes, depositando em seguida no correio. A lista se encontra no final desse texto : PASSO 2: Elimine o primeiro nome da lista (#1). Reordene a lista de 1 a 5, ou seja (2 torna-se 1), (3 torna-se 2), etc.. Coloque o SEU nome e endereÃ§o como o 6Âº(sexto) da lista. :
          PASSO 3: ApÃ³s feitas as alteraÃ§Ãµes acima, coloque este artigo em pelo menos 200 fÃ³runs e newsgroups.VocÃª pode modificar o texto deste artigo, mas por favor, mantenha a integridade da mensagem. Isto Ã© importante. LEMBRE-SE, quanto mais mensagens nos fÃ³runs, newsgroups e livros de visitas vocÃª colocar, mais dinheiro vocÃª ganharÃ¡!
          O retorno serÃ¡ melhor se vocÃª colocar um bom tÃtulo ( ou esse mesmo), que fique visÃvel para todos.
          Agora, coloque o artigo modificado (ou esse mesmo).Existem milhares de fÃ³runs e newsgroups. VocÃª sÃ³ precisa de 200. EntÃ£o mÃ£os Ã obra, LEMBRE-SE Toda vez que alguÃ©m agir como vocÃª, salvando esta mensagem, seguindo e executando corretamente todas as instruÃ§Ãµes, 6 pessoas estÃ£o sendo beneficiadas com R$ 1,00 cada e seu nome subirÃ¡ na lista. Assim as listas multiplicam-se rapidamente e seu nome vai subindo atÃ© atingir a primeira posiÃ§Ã£o. Desta forma quando seu nome alcanÃ§ar a #1 posiÃ§Ã£o, vocÃª jÃ¡ terÃ¡ recebido milhares de reais em DINHEIRO VIVO! Lembre-se que vocÃª sÃ³ investiu R$6.00. Envie agora os envelopes, suba o nome dos participantes da lista e adicione seu prÃ³prio nome na sexta posiÃ§Ã£o da lista, poste-a nos fÃ³runs e vocÃª estÃ¡ no negÃ³cio!
          COMO POSTAR NOS NEWSGROUPS --------
          Etapa 1) Copie e salve este artigo em seu editor de texto. (selecione o texto, clique em Editar e Copiar, abra seu editor de texto e clique em Editar e Colar, depois clique em Arquivo e Salvar como .txt) Etapa 2) FaÃ§a as devidas alteraÃ§Ãµes neste artigo, incluindo seu nome na sexta posiÃ§Ã£o da lista. Etapa 3) Salve novamente o arquivo. Clique em Editar e Selecionar tudo. Clique novamente em Editar e Copiar. Etapa 4) Abra seu navegador, Netscape, Internet Explorer ou algum outro qualquer e procure vÃ¡rios newsgroups (fÃ³runs on-line, cadernos de mensagens, locais de conversa, discussÃµes) e poste uma mensagem nova em cada MURAL ou ÃREA, ou algo similar. Etapa 5) Para postar entre nesses newsgroups. No campo destinado para digitar o texto ou mensagem a ser enviada para o newsgroups, clique com o botÃ£o direito do mouse. Em seguida clique em Colar. Como Assunto ou tÃtulo, digite um nome que chame a atenÃ§Ã£o, como o meu, ou invente algo parecido. Clique em enviar e pronto, vocÃª acabou de enviar sua primeira mensagem! ParabÃ©ns...Etapa 6) Selecione outro newsgroups e repita o passo 5. FaÃ§a isso no mÃnimo para 200 newsgroups. **QUANTO MAIS MENSAGENS VOCÃŠ ENVIAR AOS NEWSGROUPS MAIS CHANCES VOCÃŠ TERÃ DE GANHAR MAIS DINHEIRO ** Pronto! VocÃª logo comeÃ§arÃ¡ a receber dinheiro pelo correio. Se vocÃª deseja ficar anÃ´nimo, vocÃª pode inventar um nome para usar na lista, contanto que o endereÃ§o esteja certo para que vocÃª receba o dinheiro. **CONFIRA SEU ENDEREÃ‡O!!!.
          ------- PORQUE RENDE TANTO DINHEIRO --------
          Agora vamos ver POR QUE rende tanto dinheiro: Fazendo uma anÃ¡lise bastante pessimista, vamos supor que de cada 200 mensagens, apenas 5 dÃªem retorno. Assim das minhas 200 mensagens, receberei apenas R$5,00 referentes ao meu nome na #6 posiÃ§Ã£o. Agora, cada uma das 5 pessoas que me enviaram R$1.00 postaram mais 200 mensagens cada uma. Se apenas 5 de cada 200 retornarem, receberei R$ 25,00 referentes ao meu nome na #5 posiÃ§Ã£o. Agora, cada uma das 25 pessoas que me enviaram R$1.00 postaram mais 200 mensagens cada uma. Se apenas 5 de cada 200 retornarem, receberei R$ 125,00 referentes ao meu nome na #4 posiÃ§Ã£o. LEMBRE-SE ! Estamos considerando um exemplo extremamente fraco. Agora, cada uma das 125 pessoas que me enviaram R$1.00 postaram mais 200 mensagens cada uma. Se apenas 5 de cada 200 retornarem, receberei R$ 625,00 referentes ao meu nome na #3 posiÃ§Ã£o. Agora, cada uma das 625 pessoas que me enviaram R$1.00 postaram mais 200 mensagens cada uma. Se apenas 5 de cada 200 retornarem, receberei entÃ£o R$ 3.125,00 referentes ao meu nome na #2 posiÃ§Ã£o. Agora, cada uma das pessoas que me enviaram R$1.00 postaram mais 200 mensagens cada uma. Se apenas 5 de cada 200 retornarem, receberei nesta Ãºltima fase R$ 15.625,00 referentes ao meu nome na #1 posiÃ§Ã£o. INCRÃVEL! Com um investimento original de apenas R$6,00, cria-se uma oportunidade gigantesca. Estima-se que entre 20.000 e 50.000 novas pessoas se juntem Ã Internet todos os dias e vÃ£o para os chats e fÃ³runs. "O que sÃ£o seis reais para tentar uma chance milionÃ¡ria que pode dar certo?" As chances sÃ£o grandes quando milhÃµes de pessoas honestas como vocÃª estÃ£o se juntando a esse grupo?? Lembre-se, a HONESTIDADE faz parte deste jogo. MANDE UM DÃ“LAR AO INVÃ‰S DE UM REAL PARA OS ESTRANGEIROS .
          IMPORTANTE: O envio das cartas contendo o bilhete e R$1,00, Ã© que torna honesto e prospero o sistema, assim o sistema sobrevive, pois tudo que Ã© desonesto, mais cedo ou mais tarde, fracassa certamente.

Filename case issue in precompilation of JSPs for Windows

Hello,
          I have determined why my JSP pages have been recompiling
          despite including the corresponding compiled class files in
          my application package.
          It seems as though on Windows, any jsp files that have
          filenames that have upper
          case letters are being recompiled, even if their precompiled pages
          are included in the .war file. JSP files that have filenames that are all
          lower case
          are not recompiled, which is expected behavior.
          The UNIX version of BEA does not seem to have this bug
          related to the case of JSP filenames.
          Could someone from BEA please give us more information
          on this issue and when we can see it fixed?
          Thank you very much,
          Peter Kim
          p.s. I am using Weblogic Server version 7.0.1.0.


I'm seeing something slightly different here.
          I'm including __MyJsp.class (with the proper case) in my
          packaged .war file, but when a request is made for MyJsp.jsp,
          BEA looks for __myjsp.class instead of __MyJsp.class--
          therefore it recompiles MyJsp.jsp.

Precompilation of JSPs for default web application

Hello,
Once in a while I need to redeploy my "Default" web application. I would like to have its all JSPs precompiled, so that it was immediatly available after redeployment.
However, if I try to redeploy my web application (.war file) under, let's say, "DefaultWebApp" root context, using the administration console, with the "Precompile JSPs" option enabled, it does compile all JSPs, but ONLY those deployed under the "DefaultWebApp" root context.
However, If I access a url like "http://somehost/SomeResource.jsp" (a file that belongs to that default web application"), I can see (due to a pause) that my JSPs have not been compiled under the root context.
Is there any way to precompile JSPs for my default web applications?
Sincerely,
Sergei Batiuk.

Weblogic Precompilation of Jsps

Hi there,
          I'm deploying a project to Weblogic 8.1.2 and I'm trying to use Ant - in conjunction with Weblogic tasks - wldeploy and wlappc - to build and deploy my project for me. And I'm noticing some bizarre behaviour with the weblogic precompilation.
          As part of the build process - all jsps are precompile when assembling into an ear file. However when I deploy the ear - Weblogic Server goes ahead and recompiles the jsps all over again - which the defeats the purpose of compiling them at assembly time.
          The message I get from the server is
                    16-Aug-2004 10:45:53 o'clock BST> <Info> <HTTP> <BEA-

          WebLogic Server.JSP build version: 8.1.2.0WLS build

                                        Does anyone know how I can stop this second precompilation?
          Thanks in advance

Precompiling a JSP that uses a bean

Hi,
          I am facing a problem when I startup Weblogic with precompiling ON.
          I have a JSP that uses a bean. When the JSP is being compiled, Weblogic is
          actually trying to instantiate the bean and is executing code in the
          constructor of the bean !
          When I use the weblogic.jspc compiler to compile the JSP, no such thing
          happens.
          So this happens only when I precompile such a JSP when starting up Weblogic
          server.
          - Why does weblogic attempt to instantiat the bean ?
          - Is there any way to tell weblogic "dont instantiate this bean now" ?
          Also, the compiler is unable to find a class that is required by the bean. However, this class is there in the /applications/..../WEB-INF/lib in a JAR file. So why is the class not being found ?
          Thanks,
          Jay


Do a stack trace from the constructor to determine who is calling it, and
          maybe why ...

Precompile the JSP file

I try to use the weblogic.jspc to precompile all the jsp file to :
          DefaultWebApp_myserver\WEB-INF\_tmp_war_myserver_myserver_DefaultWebApp_myse
          rver\jsp_servlet
          But when I visit the JSP page from browser, it seem like the weblogic
          compile it again
          Any help??

Hi, David:
Since this is 9.0.4, I would suggest you that you try the following,
. create directories build, build/ear, build/ear/app
. extract the ear to build/ear so that you have build/ear/app.war
. cd build/ear/app and extract you app.war to build/ear/app
. mkdir -p WEB-INF/classes
. ojspc -srcdir WEB-INF/classes -dir WEB-INF/classes yourOtherOptions <list_of_your_jsp_files>
. now you can repackage ear. As long as the jsp page implementation classes are in WEB-INF/classes or packaged in a jar under WEB-INF/lib, jsp engine will be able to use them if the main_mode is set to justrun in web.xml of the war file or the global-web-application.xml of oc4j installation.
The main point here is to use the expanded structure to see if that will solve your problem. Other options includes upgrading to 9.0.4.2 (is 9.0.4.3 out?) or even 10.1.3, filing an oracle support ticket. Lastly, you may contact me directly.

Precompilation of jsp

          When I set my web application to have its jsp's precompiled when the server starts,
          the web application does not deploy because a jsp failed to compile. What do I
          need to do to tell the compiler to keep going, so that the web app can still be
          deployed? I am using the JSP Descriptor GUI from the WL Console.


          Set the -k option on the jsp compiler.
          -k
          When compiling multiple JSPs with with a single command, the compiler continues
          compiling even if one or more of the JSPs failed to compile.

JSP precompilation and my .java files compilation issues / building WAR file using ANT

Hello.
I am new to working with WAR files and the whole process of it. A little
background on what we are using. We are using, WLS 6.1 SP3. I am using the
ant.bat that is supplied in the bin directory of the WLS install.
I am trying to work with ANT and getting it to build the file. I am making
progress, but at a point where I am having trouble getting my java code
files to compile using ant. I am having one issue and looking to do one
other item.
1) I would like to precompile the JSPs if possible prior to putting into the
WAR file. Not sure if this is done or not, but there was a utility when I
was working with ibm's app server that gave us the ability to do a batch
complile. Was thinking that maybe a similair concept is possibly here.
2) Having issue getting ant to compile code properly. In the compile
section of the build.xml file for ant, I tell it where the source files are,
and the destionation folder for the compiled class files. I then try to set
the classpath so that it finds the .jar files that are necessary for my
source files to complile. But, it won't find them. And not sure how come.
I may be going about this all wrong, but dont know. Here is the compile
section of the build.xml I am using:
<target name="compile" depends="prepare">
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
classpath="$(lib.home)"
debug="on" optimize="on" deprecation="off"/>
</target>
One note, I've tried many different items in the classpath line, which
don't work. if I do *.jar it fails at complie time, invalid argument. As
well as if I use *.* and so on. if I list the explicit file names, it still
doesn't seem to find them.
I was wondering if anyone could help, if you need anymore information let me
know, I can send the entire build.xml if necessary. I may be missing
items, seeing that this is my first try at using ANT.
Any help is appreciated and thanks in advance. Hopefully not sounding too
off the wall. Hopefully get some clarification and understanding.
Thank you.
Kevin.

http://e-docs.bea.com/wls/docs70/jsp/reference.html#57794
or just set the precompile flag in weblogic.xml
You can configure WebLogic Server to precompile your JSPs when a Web
Application is deployed or re-deployed or when WebLogic Server starts up
by setting the precompile parameter to true in the <jsp-descriptor>
element of the weblogic.xml deployment descriptor.

maybe because you are not using curly braces there on lib.home??
if you do it the way above, you would have to list all your jars
classpath="$(lib.home)\lib1.jar:$(lib.home)\lib2.jar"
or you can nest
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
debug="on" optimize="on" deprecation="off">
     <classpath>
          <fileset dir="${lib.home}" includes="*.jar" />

Precompiled JSP Compatibility Problem

I am a developer in the Cross Applications Unlimited group. We are experiencing a problem with precompiled jsps in a ADF web application that we have developed. Any help that you can provide with this problem would be much appreciated. Neither Oracle forums nor the internet have yielded any leads to us so far. Here are the specifics of our problem.
In our application, we precompile our JSPs when the EAR is built. The application was initially developed in JDeveloper 10.1.3.2 and worked without problems when deployed to OAS 10.1.3.2. However, our application server MTR recently shifted to OAS 10.1.3.3. We migrated our workspace and projects to JDeveloper 10.1.3.3 and rebuilt our EAR file in JDeveloper 10.1.3.3. We are getting "500 Internal Server Errors" when this new ear file is deployed to OAS 10.1.3.3. The error does not always manifest when running the application. We can login and navigate to JSPs linked directly from our navigation menu (our first level pages). However, in these first level pages are buttons that navigate to second level pages. The error is being seen whenever we try to access one of these second level pages. Everything else about the application works fine. When we don't precompile our JSPs and deploy, the application works fine.
This is the error we find reported in our application logs...

Hi Ian,
Add this jar file to classpath...use either web interface or directly edit jvm12.conf to modify classpath..

Precompile JSP's in Weblogic 5.1/SP6

          Hello,
          How do you get the precomplilation of JSP's to work in 5.1? I have
          seen some emails on this mailing list about how to precompile the
          JSP's in 6.0 but I would like to know how to do it in 5.1. looking
          at the documentation here: http://www.weblogic.com/docs51/classdocs/API_jsp.html#register
          In the weblogic properties file we have them set as follows:
          weblogic.httpd.documentRoot=htdocs/
          # WEBLOGIC JSP PROPERTIES
          # Sets up automatic page compilation for JSP. Adjust init argsfor
          # directory locations and uncomment to use.
          weblogic.httpd.register.*.jsp=weblogic.servlet.JSPServlet
          weblogic.httpd.initArgs.*.jsp=\
          pageCheckSeconds=1,\
          keepgenerated=true,\
          compileCommand=d:/jdk1.2.2/bin/javac.exe,\
          workingDir=D:/Mediaprise/mpsite/WebLogicServer,\
          verbose=true
          that should be picking up any JSP's underneath the document root
          folder (htdocs, in this case) and precompile them to the working
          dir. now we have JSP's in the htdocs folder and a whole stucture
          of JSP's underneath the htdocs folder in a folder called JSP with
          it's own file and directory structure. The weblogic.log file shows
          that the above properties are being set correctly on startup but
          no precompilation seems to be happening to the working dir. any
          ideas on how to make this work in 5.1??
          I am working on Weblogic 5.1 with SP6.
          Thanks,
          Gagan


In WebLogic 6.0 register each jsp in the web.xml with a <servlet-name>, <jsp-file>
          and <load-on-startup>. For example:
          <web-app>
          <servlet>
          <servlet-name></servlet-name>
          <jsp-file></jsp-file>
          <load-on-startup></load-on-startup>
          </servlet>
          <servlet-mapping>
          <servlet-name></servlet-name>
          <url-pattern></url-pattern>
          </servlet-mapping>
          </web-app>
          The optional value of load-on-startup element must be a positive integer indicating
          the order in which the servlet should be loaded.
          In WebLogic 6.1 set the precompile parameter in weblogic.xml.
          <jsp-descriptor>
          <jsp-param>
          <param-name>
          precompile
          </param-name>
          <param-value>
          true
          </param-value>
          </jsp-param>
          </jsp-descriptor>

Precompiling jsp's in weblogic

Hi ,
I want to precompile my jsp's when I start the server. I don't want wait for long time when the page start's loading. Can we do this in weblogic.
Any help will be appreciated.
Thanks
Anitha

hi anitha,
yes you can do that in Weblogic by setting up the precompile parameter for <jsp-descriptor> element to be true in weblogic.xml descriptor file when the web application gets deployed or re-deployed !!

JSP Precompilation Issue:

I'm trying to precompile my JSPs so that the .class files can be included along with the WAR.
For this pre-compilation , i'm using the jspc ANT task.
I have the following issues:
1) A number of JSPs have HTML pages included in them.
     Say my JSPs are in a folder : jsp
     and HTMLs in a folder :html
     The JSPs include the HTML with this TAG :
          <%@ include file="//html/myHtml.html" %>
     When i try to run the jspc task for the first time, I get an exception indicating that //html/myHtml.html has not been found.
     I do not make any changes, but run the ant task again, The JSPs are convered to Java files.
     I'm not able to figure out what happens the first time i run the ant task
2) Once i run the jspc task, i run the javac task to compile the JSP converted JAVA files.
Since a lot my JSPs have other JSPs included in them, i get several compilation errors caused by the included JSPs
Should the JSPs be compiled in the order that they are included in the JSPs?
3) I'm using Tomcat 4.1. to host the web appln. What are the modifications i need to make to use pre-compiled JSPs in the WAR file?

Simply change the file extent on the JSPs that are only included. The extent ".jspf" (JSP fragment) is a reasonable convention.
