JSP compilation 65535 bytes limit

Vidyadhar-2
Hello Team,

Recently we did a upgrade existing tomcat from 7.0.42 to 7.0.76 on windows
box. Post the up gradation we are seeing following error in couple of JSPs

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: [231] in the generated java file: [C:\Program
Files\Apache\Tomcat\work\Catalina\localhost\app\org\apache\jsp\jsp\applicationChange\applicationChangeMain_jsp.java]
The code of method _jspService(HttpServletRequest, HttpServletResponse) is
exceeding the 65535 bytes limit

Stacktrace:
org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:103)
org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:366)
org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:490)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:379)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:354)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:341)
I have checked the various threads on tomcat support archive and did try
following solution which did not work on 7.0.76 as well as on 7.0.77.

1. Following changes in conf/web.xml
<init-param>
    <param-name>mappedfile</param-name>
    <param-value>false</param-value>
</init-param>
<init-param>
    <param-name>compiler</param-name>
    <param-value>modern</param-value>
</init-param>
2. Increased the buffer size.

Can some one suggest some ways to resolve this error, without downgrading
to 7.0.42

Try adding following init parameter in <tomcat_home>/conf/web.xml

<init-param>
     <param-name>mappedfile</param-name>
     <param-value>false</param-value>
</init-param>

Have you restarted service post adding parameter ?

Re: JSP compilation 65535 bytes limit

In reply to this post by Vidyadhar-2
I have two things which you might want to try out:

1) You will lose your JSP debugging capability - but if that's not your
concern, then in your CATALINA_HOME\conf folder append this for "JspServlet"

        <init-param>
            <param-name>mappedfile</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>suppressSmap</param-name>
            <param-value>true</param-value>
        </init-param>

     This will stop generating JSR45 debug info and Symbol Maps for JSP
pages ( I think I have said technical things right here, otherwise please
correct me!).

2) I sincerely recommend moving scriptlet code out of your JSP and remove
all unwanted/commented code, newline/carriages from your JSP. Even with the
config above, this might fail since the code is genuinely too large for
__jspService().

3) If possible, try to use Ant and precompile your JSP and iterate through
the .class files to check which method size is larger or close to 90% or
the 64k footprint. You can write a short program by leveraging java.io and
Apache commons BCEL library. Ant has a strange behaviour which doesn't
throw any exceptions if the Jsp method size exceeds the limit. But the
compilation occurs anyway. So you can go through those compiled files using
your custom tool and print the size of the methods.


I hope this helps you.

We already tried this option. We included these lines in tomcat's web.xml
file and restarted the services, but still it is giving the same error.

Re: JSP compilation 65535 bytes limit

Hi Vidyadhar,

Some points to note here:

1) Setting those parameters in Web.xml file (CATALINA_HOME/conf) doesn't
guarantee that it won't happen. Tomcat 8.0.43 onwards have got this relaxed
out by using a more efficient error handling code. But you will have this
error if the code is truly hitting near the limit.
2) The issue occurs with Tomcat 8.0.39 onwards. Try to see if the issue
happens for tomcat 8.0.29. I can vouch for 8.0.29 where it didn't happen.
3) Did you try and follow my suggestion on point 3 (last email) about
checking the method sizes of the precompiled JSPs using apache commons BCEL
(bcel-5.4.1.jar) library? If yes, what did you find?


You also haven't mentioned what sort of JSPs you have that yields into such
error. Are you having legacy scriptlets which are quite heavy and uses lots
of custom tags? Try to use the following too:

<init-param>
<param-name>trimSpaces</param-name>
<param-value>true</param-value>
</init-param>

The above is having some inconsistency reported in a different email
thread, but I assume it should be fine in most of the cases. Try to see if
you can provide some results on the above points.

I already tried to precompile the JSPs using ANT but it is giving following
error:
C:\apache-ant-1.9.4\tomcat.xml:11: org.apache.jasper.JasperException:
java.lang.IllegalArgumentException: Page directive: invalid value for import
        at org.apache.jasper.JspC.processFile(JspC.java:1296)
        at org.apache.jasper.JspC.execute(JspC.java:1415)
        at
org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:292)
        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
I guess I am hitting the bug # 57099 and there are multiple JSPs wherein we
need to do these changes.

Your ant Build File seems to be incorrect. Could you provide the snippet of
the Jspc Task and Javac task for this?

Re: JSP compilation 65535 bytes limit

Mohammed Manna
You cannot blindly execute the snippet by copying it from Tomcat website.
You have to adapt it to your project first. Try and remove the <import
file> line and try to build it. You probably need to set up your project
for Ant build first if not done already.

Project is already setup and same set of build file is working fine with
different version of Tomcat. If we remove the import task for this
particular project we are seeing some different error which is regarding to
ANT and not related with Tomcat or JSP compilation.
Snippet of catalina-tasks.xml is as follows ( and this is the only file
included in import):

<project name="catalina-tasks">
  <description>Catalina Ant Manager, JMX and JSPC Tasks</description>
  <!-- set catalina.home if it's not already set -->
  <dirname property="catalina.home.bin.dir"
file="${ant.file.catalina-tasks}"/>
  <property name="catalina.home" value="${catalina.home.bin.dir}/.."/>
  <typedef resource="org/apache/catalina/ant/catalina.tasks">
    <classpath>
      <fileset file="${catalina.home}/bin/tomcat-juli.jar"/>
      <fileset dir="${catalina.home}/lib" includes="*.jar"/>
    </classpath>
  </typedef>
  <typedef resource="org/apache/catalina/ant/jmx/jmxaccessor.tasks">
    <classpath>
      <fileset file="${catalina.home}/lib/catalina-ant.jar"/>
    </classpath>
