JSP pre-compilation issues

Hi,
I'm trying to pre-compile one of our web applications using Jasper2 and i'm getting build failures. Our setup is like this,
In A.jsp
-- defines a use bean 'test'
--- includes B.jsp
In B.jsp
-- uses the bean 'test' to perform some operations
The pre-compilation steps fails effectively because b.jsp doesnt know about the use bean 'test'. Is this approach fundamentally wrong or is there any flag in the compiler settings we can use to solve this case. This is a third-party web apps which i'm trying to integrate into our solutions. Any help is appreciated.
Thanks
Mustafa

Help with JSP pre-compiling

We have a web application using Jboss4.0.5, jdk 1.6 and And 1.6.5, and now we try to do a pre-compiling as part of our build procedure.
That is the first time I am going to do a pre-comp of a major application, which includes about 1700 jsp files.
The directory tree of the application is as follows:
/project
    |--- > /web_pre-comp/pages/jsp ( it contains all the jsp files )
    |----> /web_pre-comp/WEB-INF ( it contains the web.xml file.)
    |----> /web_pre-comp/WEB-INF/tld ( it contains the tld files)
    |----> /web_pre-comp/WEB-INF/src ( it coutains the generated src file from jsp )
    |---->/web_pre-comp/WEB-INF/classes ( it contains the compiled classes once the jsp java files are generated.   )
    |----> build.xml ( the ant script )And there is my build.xml file looks like:
<project>
      <target name="pro.jsp.generate" depens="init">
       <java classname="org.apache.jasper.JspC" fork="yes">
          <classpath refid="tomcat.jsp.classpath"/>

          <arg line="-webapp"/>
          <arg value="${jsp.src.dir}"/>
       </java>
   </target>
</project>When I was running the ant script, I received such message:
[java] org.apache.jasper.JasperException: The absolute uri: http://www.prounlimited.com/wandappconfig.tld cannot be resolved in either web.xml or the jar files deployed with this application

Another side questions is when some java file are created from JSP, I see some "005f" included in the java file name, such as "inc_sup_princing_view.jsp" creats a
"inc_005fsup_005fpricing_005fview_jsp.java" file. Does someone know why this happen ?
Thanks a lot !

We have a web application using Jboss4.0.5, jdk 1.6
and And 1.6.5, and now we try to do a pre-compiling
as part of our build procedure. Hi Charlie,
According to your ant build script you're using Jasper compiler, but your web container is JBoss.
I know that Tomcat uses the Jasper compiler --- but I don't know if JBoss supports Jasper or not. Please check with JBoss if they support Jasper, if not they my support a different pre-compiler.
That is the first time I am going to do a pre-comp of
a major application, which includes about 1700 jsp

The 005f is expected, it is for internal reference for the pre-compiler, nothing to worry about.

"Java file" & "Jsp file" compilation issues in Eclipse

Hi,
Eclipse
Question 1:
I have set the value for preference->java->Installed JREs as : j2re1.4.2_07 not to jdk
When I write a java file, its compiling, how? From where its using "javac" exe file for compilation.
Question 2:
Whereas in prefrence->Tomcat->JVMSettings -> JRE(drop down box) set value as j2re.1.4.2_07
When I write a jsp file as follows
index.jsp
<html>
<body>
<%java.util.Date d = new java.util.Date();%>
Todays date is <%= d.getDate()%> and this jsp page worked!
</body>
</html>
when i try to save this file & strat tomcat I got exception as follows:
Exception:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null
Generated servlet error:
[javac] Compiling 1 source file
Please clear my doubts.
Thanks,
Hari

Try going into your TOMCAT_HOME/conf/web.xml and look for this section:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>logVerbosityLevel</param-name>
<param-value>WARNING</param-value>
</init-param>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
Change the <param-value> for fork from false to true and see if that helps.
Otherwise it's a problem with your JSP.

Any way to pre-compile .jsps in batch?

When I start my application and first hit a page, I notice that some .jsps that have changed take a while to compile. Is there way to pre-compile all of my .jsp files after I start my app so customers won't notice any slowdown when they first hit a page? I am currently deploying on Weblogic 6.1 service pack 3. Many thanks!

JSPs are only compiled once per page, at the time the first user executes it. This means that any time a page is changed, it is recompiled the first time the page is loaded, but any subsequent access to that page does not require a recompilation... note that once one person has accessed the page, the compiled class is stored on the server and is accessed directly until a change is made. As such, the slowdown of recompilation is never really a huge issue, since changes to the JSPs are generally infrequent enough, and even when changes are made, only the first person to access that page after changes have been made would notice any difference at all.
If you were particularly concerned, you could perhaps create some sort of script that would attempt to access each page once, thus forcing a compile and updating the classes on the server, but this would generally be considered unnecessary.

Pre-Compiling JSPs while deploying a .war file in OC4J instance

Hi,
Is there any way to inform the OC4J instance to pre-compile the jsps in a .war file, while deploying..
Thanks for your responses,
Eshwar

Click on the project.
Open the context menu (right mouse button).
Expand the General item in the left list.
Select the Deployment Profiles item.
Select the deployment profile you need from the right.
Follow the wizard.

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.

What is the Advantage and Disadvantage of Pre-Compiled JSP

Hi All,
What is the advantage and disadvantage of using pre-compiled JSP

Pro:
By pre-compiling your JSPs you don't need a java compiler on the server - just a jre.
The result? No java compiler on the server means a potential security hole patched - people can't just write and deploy jsp's willy nilly on the server.
You KNOW that all your JSPs compile before you visit them - because you have compiled them all :-). It won't fail because of a stupid spelling miskate that prevents compilation. That doesn't mean they will run without error of course...
Con:
Compiling the JSPs ties them to a particular server - unless you take the runtime along with them.

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.

Problem with pre-compiling jsp's

          hi,
          we have an .ear running on wls 6.0 sp2.
          Our app has a web component(part of the .ear) as well which has tld's & jsp.We
          are following the struts framework.
          We configured the <jsp-descriptor> element in the weblogic.xml file to pre-compile
          the jsp's..but the server complains of the following
          any suggestions would be appreciated

          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/

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-Compiled JSPs.

Hi Gurus,
          The weblogic compiles the JSP pages, the package names of the servlets
          generated contains the directory structure along with the package prefix.
          i.e . if the jsp file calles myfile.jsp is in
          public_html/cm/log/myfile.jsp
          the servlet class generated with package
          <package_prefix>._cm._log.myfile.class in
          public_html/<package_prefix>/_cm/_log/ directory.
          If the JSPs are compiled from command line , using "java weblogic.jspc
          ... " it does not generate the "_cm._log..." package prefix.
          Right now I want to write a script to pre-compile all the JSPs after
          deployement.
          Thanks in Advance and Regards
          Arun


Hi,
          Try to use the -package option with weblogic.jspc.
          Best Regards

Pre compiling of jsp

HI,I am using weblogic5.1 and I am unable to pre compile the jsp file. I used java weblgoic.jsc command to compile the files, but I am unable to complie some of the jsp files. Can you suggest me a better way to pre comile files and directories.Thanks,Prakash Appani


If you can compile some, but not others, then it is more than likely that
          you have problems
          with your JSP's. You may want to use the regular javac to compile them.
          # WEBLOGIC JSP PROPERTIES
          # Sets up automatic page compilation for JSP. Adjust init args for
          # directory locations and uncomment to use.
          weblogic.httpd.register.*.jsp=\
          weblogic.servlet.JSPServlet
          weblogic.httpd.initArgs.*.jsp=\
          pageCheckSeconds=1,\
          compileCommand=c:/jdk1.2.2/bin/javac.exe,\
          workingDir=C:/weblogic/myserver/classfiles,\
