Error in jsp execution: exceeding the 65535 bytes limit

[14年前 に Sam Wan によって更新されました。]

Hi,

I dont' kown whether this is memory issue or my jsp file is too large to be delt with by the java compiler.
Here is the error I got when the jsp pages executed:

23:13:07,401 ERROR [IncludeTag:79] Current URL /web/guest generates exception: Unable to compile class for JSP: 

An error occurred at line: 417 in the generated java file
The code of method _jspService(HttpServletRequest, HttpServletResponse) is exceeding the 65535 bytes limit

Stacktrace:

My server has only not enough 1GB memory. Is this the problem?

Thanks
Sam

Hi Guys,

This looks like a bug that was fixed here:

http://issues.liferay.com/browse/LPS-7003

The fix is to change the .jspf file to a .jsp file (and changing some variables).

Thanks Amos, will try this...

Even without the fix - keep in mind, that a jsp is compiled into a java servlet class that outputs all the HTML code that you had in your jsp and also contains all the code that you wrote in the scriptlets on that jsp.

This servlet class will be compiled by javac to bytecode, loaded by the classloader and executed as if you wrote a servlet with loads of

pageContext.getOut().write("<div>some HTML stuff</div>");

There's a java limit for a single method to contain only 2^16 bytes. So if you hit this limit you almost always have too a very complicated jsp and can work around this by externalizing parts of it to proper java classes and just call them from the jsp, shrinking your jsp dramatically. I've seen this more with generated jsps than hand written ones, as writing (and maintaining) such a beast will be a lot of pain...

Now that you understand the root cause, you might be able to work around it without applying a patch. Note: I've not taken a deeper look at the linked (fixed) issue - might be that you need the patch nevertheless, but you'll figure that out...

Hi Tarun and Sam,


Hope content size of jsp file is exceeded. just split that jsp file and include one inside another.

Hi sam,

Hope you have got solution for this. If you still haven't got any answer for this then please find below solution. It works fine.
Go to Tomcat path then config folder where you will find web.xml file . Find Servlet name with jsp. add
<init-param>
<param-name>mappedfile</param-name>
<param-value>false</param-value>
</init-param>
Because tomcat can not handle without this.
final jsp servlet tag:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>mappedfile</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
Hope this solution will work for your crucial problem.

Thanks & regards,

I got it resolved  by adding a parameter  in web.xml in tomcat/conf/web.xml

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

 

And final attribute looks like

<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value> 
</init-param>
<init-param> 
<param-name>mappedfile</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
