How to pre-compile JSP?

Does anyone know how to pre-compile JSP so as to get faster browsing response?

I know little about JSPs but from what I can remember, JSPs are compiled first time when they are being asked to be executed .Unless changes are made to those programs they would not be compiled, as a result of that, it would run faster. Correct me if I am wrong though

Pre-Compiled JSP

Hi All,
Can anyone tell me, how to pre-compile jsp and deploy it in Tomcat and Websphere and also how stop the app server recompiling the JSP at runtime. Searched the net for but was not really that successful.

Read the documentation that come along the application server. For Tomcat it's for example this: [http://tomcat.apache.org/tomcat-6.0-doc/jasper-howto.html].

How to pre-compile a JSP

Hi all,
I struckup with a doubt as fallows
How to pre-compile a JSP to Servlet(.class file) bfore the first request ,so that the first response takes same time as later responses.

Thanx Ram for ur response,
I know Tomcat is assembled with Jasper compiler.My actual doubt is I want to precompile the Jsp bfore the first request. Actually the compilation occurs at the time of first request.U said it is server specific ,can u plz s let me know the pre-compile option for WEBLOGIC Server.

Pre-compiled JSPs getting re-compiled by the server

For our project we are using wlappc to pre-compile JSPs and generate EJB classes. We are using the split directory format, so this is what the task looks like -
<target name="appCompile" depends="init" >
<delete dir="${ear.dist}" />
<mkdir dir="${ear.dist}" />
<wlpackage srcdir="${ear.src}" destdir="${ear.build}"
toDir="${ear.dist}" />
     <wlappc source="${ear.dist}" verbose="true" classpath="${classpath}" />
</target>
After this, we are using wldeploy to deploy the application to another server.
This is how the task looks like -
     <target name="beadeploy" depends="init" >
     <wldeploy action="deploy"
          source="${src.dir}/dist/myapp.ear"
          name="myApplication" remote="true"
          user="${deploy.username}" password="${deploy.password}"
          verbose="true" adminurl="t3://${deploy.host}:${deploy.port}"
          upload="true"
          debug="true" targets="${deploy.target}"/>
     </target>
The problem that I am facing is that, even after re-compiling the JSPs, they get compiled again by the server when accessed for the first time !
We using Weblogic 8.1.2.0. Can you please provide a soplution for this ?

Hi,
The following steps help you troubleshoot why you may be having problems with JSPs recompiling:
1. When invoking jspc, your classpath must contain the same release, service-pack, and any temporary patches as the servers you wish to deploy on. Otherwise, the Server will read the JSPs as being compiled on a different version of the WebLogic, and will recompile them all.
2. You should invoke jspc from the root directory of your open-directory exploded) WebApp or specify -webapp) and use the -d option to deploy the generated classes to the WEB-INF/classes directory. You can then archive these JSP classes into a JAR if you wish from the WEB-INF/classes directory.
3. The JSPs should then be deployed either individually to the WEB-INF/classes/jsp_servlet directory or in a JAR file under the WEB-INF/lib directory.
4. One other thing that could cause JSPs to be recompiled is if the timestamp of the class is different from that of the source.
Also, if your ant classpath is different from whatever WLS-related classpath entries you use to run WLS, this may cause problems, too.

How to pre-compile JSF pages?

Hi,
I am new to JSF and would appriciate if any one can help me find out how to pre-compile JSF pages?
Thanks in advance
satsdn

The same way you pre-compile JSP pages: Set it up in your faces-config.xml file.
Here's how I do it:
     <servlet>
          <servlet-name>AcctID</servlet-name>
          <display-name>AcctID</display-name>
          <jsp-file>/AcctID.jsp</jsp-file>
          <load-on-startup>-1</load-on-startup>
     </servlet>Put one of these tags for each JSP you want to pre-compile. The -1 load-on-startup value is important.

Pre-compile jsp in Weblogic

Hello all,
          I have been trying to add following tags in weblogic.xml to precompile my all jsps at Deployment time, but it gives me error as follows. [I am pasting messages from the console....]
          I am using WL express 7.0 and jdk1.3 that comes along with the server.
          Here is my tag:
          <jsp-descriptor>
               <jsp-param>
                    <param-name>precompile</param-name>
          <param-value>true</param-value>
               </jsp-param>
          </jsp-descriptor>
          What is the wrong here ? Is there any special configuration in weblogic server that I am ignoring here ?

          And make sure you don't have any other patches installed!
          The generated servlet specifically checks to make sure that the servlet is running
          on the same EXACT setup (service pack, patches, etc.) that was used to generate
          it from the original JSP.

Pre-compiled JSPs when deploying an EAR under WebLogic 6.1 SP4

Hello,
We have sucessfully pre-compiled JSP pages when working with and
deploying WAR files (WebLogic 6.1 SP4, Windows).
However, we can't seem to make it work when deploying EAR files.
Examing the "secret" unpacked directories after deployment doesn't
seem to help.
If we extract the WAR from the EAR and deploy it, everything is perfect.
Any ideas? Anyone able to make this work? If so, could you share the
output of
jar -tf yourCoolEarFileThatWorks.ear
as well as the same for the embedded WAR file?
Thank you,
Mike Leo

Some followup information.
We've changed the place where it looks for JSP classes using the
"workingDir" parameter in weblogic.xml.
And we also set "pageCheckSeconds" (also in weblogic.xml) to "-1".
Now, everything in the base directory comes up without being recompiled.
However, nothing in subfolders of the base directory is "picked up". Those
pages are still being compiled when they are accessed.
Any ideas welcome.

Auto deploy pre-compiled JSP

Hello
In the post of gadegaard in november 2002, there was a problem to au deploy pre-compiled JSP. Is this problem has been fix in the 9.0.4 OC4J version ?
If yes, is it sufficient to create a "_pages" directory in the war (the war is contained in an ear) and auto deploy it ? Because my pre-compiled JSP are not deployed.
Tanks in advance for your answer
Emmanuelle

Emmanuelle:
There are two ways to use the precomiled JSP files.
Method one: You can just copy the generated JSP page implementation classes to the directory application-deployments/yourApp/yourWebApp/persistence/_pages. If the init-param "main_mode" of jsp servlet of your web app is reload, then these classes will be used without stopping the server. This is the fastest way in development.
Method two: You can packaged the generated JSP page implementation classes into a jar just like any other java class libraries. Then create your war with that jar inside WEB-INF/lib. Make sure the init-param "main_mode" of jsp servlet in your web.xml is justrun. Now you have a deployable war file. You can deploy the war file (within an ear file) to oc4j and access the JSP page.
Please tell me if either of thse methods works for you
Please note since oc4j 10.1.3, ojspc will package the generated classes into a jar under WEB-INF/lib if given an war or ear file.

Pre compiling JSPs?

Is there anywayto pre-compile JSPs for a web project outside of Workshop, for example
using the wlwBuild.sh tool, or some existing bea ant task?
Thanks,
Byron

Byron,
Building the project/application will cause the jsp's to be compiled into
the .workshop directory. Currently there is no mechanism by which the build
process can determine if the JSP has been modified, hence the JSP will be
rebuilt , during the next build.
Is there a reason why you would like to precompile the JSP outside Workshop

Pre-compiled JSPs not being recognized (WLS 8.1 SP2)

          We're running into a strange problem here, where our pre-compiled JSPs (precompiled
          via an ant target) are being recognized as "stale" and recompiled by Weblogic,
          as the following log message indicates. The strange thing is, on one hand it says
          they were precompiled by a "different" version of Weblogic server, and then right
          after that, immediately contradicts itself by logging the SAME version for the
          JSP and WLS builds:
          ####<Jan 31, 2004 11:24:40 AM PST> <Info> <HTTP> <ladybug> <fwmharris-ms01> <ExecuteThread:
          '11' for
          queue: 'default'> <dhecking> <> <BEA-101295> <Recompiling JSP
          [ServletContext(id=20425572,name=fwmhis-www,context-path=)], resource
          [tiles/table/td_twisty_group_tile.jsp], because it is stale. It was previously
          compiled using a
          different version of WebLogic Server.
          JSP build version: 8.1.2.0
          WLS build version: 8.1.2.0.>
          As can be seen, the two build versions are identical (8.1.2.0) which is the correct
          version (Weblogic 8.1 SP2). Has anyone else run into this problem? If so, is there
          a fix?
          The platform is Solaris btw.
          Thank you.

          Your guess is correct. Unfortunately a the message logged is wrong. A
          patch for CR133453 fixes that. Basically its failing (2) and logging the
          same message as (1).

Pre-compiling JSP's

I am using build.cmd to create an ear and war of my application. I am
          having problems with the code below:
          @REM Create WAR file
          COPY src\dd\war\WEB-INF\* stage\WEB-INF
          COPY src\dd\war\WEB-INF\tlds\* stage\WEB-INF\tlds
          java -classpath %CLASSPATH%;./stage/WEB-INF/classes;./src/jsp;./stage
          weblogic.jspc -docroot src/jsp -d stage/WEB-INF/classes src/jsp/*/*.jsp
          jar cv0f stage/edeploy2WAR.war -C stage WEB-INF -C src/jsp .
          On the third line (the one that starts with java) - I get the following
          error:
          [jspc] warning: expected file C:\edeploy2\src\jsp\WEB-INF\web.xml not found,
          tag
          libraries cannot be resolved.
          [jspc] parsing /*/*.jsp:

          Error: [jspc]: 1 file(s) failed:
          /*/*.jsp
          I am trying to pre-compile all the jsp's that are located in 10
          subdirectories under src/jsp/.. subdir
          I shouldn't need a web.xml file should I?
          Thanks,
          Matt


I am now using the following command, which seems to work:
          java weblogic.jspc -compileAll -webapp src\jsp -d stage/WEB-INF/classes
          However, when it begins, it looks for WEB-INF in src\jsp - is there anyway
          to make it look in src\dd for WEB-INF?
          Secondly, I added src/WEB-INF/web.xml for my tag libraries, but now I get
          the following:
          [jspc] resolved taglib uri 'RDBMS' to taglib-location
          ../../src/dd/WEB-INF/tlds/

          Any ideas?
