I am getting a javax.servlet.jsp.JspException
in one of the jsp files that my website is trying to render (survey.jsp
). However, the stack trace does not give me the the specific line in jsp where it fails but rather the line number where it fails in (survey_jsp.java:787
), which seems to be the compiled JSP file. Where do I find such files, so that I know what line is throwing this exception?
Thanks
EDIT: These files live in the /work
directory if you are using tomcat as Will suggested in the comment below.
In order to deploy Java Server Pages (JSP) files, you must place them in the root (or in a subdirectory below the root) of a Web application.
If WebLogic is compiling JSP (i.e. if you are not precompiling them), they should be located under domain_name/servers/server-name-1/tmp/_WL_user .
When you deploy a web app with a JSP, the whole translation and compilation step happens only once in the JSP's life. Once it's been translated and compiled, it's just like any other servlet.
The class files are compiled into the web module's WEB-INF/classes directory. The class files are compiled into the web module's WEB-INF/classes directory.
The compiled JSP files are by default available in the /work
folder of the Tomcat environment. There should be a subfolder Catalina
which in turn has a subfolder representing the domain name which defaults to localhost
. There in turn should be the project folder which in turn contains package hierarchy org.apache.jsp
with therein the compiled JSP files.
Tomcat |-- backup |-- bin |-- conf |-- lib |-- logs |-- temp |-- webapps `-- work `-- Catalina `-- localhost `-- projectname `-- org `-- apache `-- jsp |-- survey_jsp.class `-- survey_jsp.java <--- here
Unrelated to the concrete problem, there should be a root cause part in the stacktrace of the JspException
which usually contains more detail about the real root cause of the problem. Read a bit further in the stacktrace. By the way, do you know that putting raw Java code in JSP files is considered a bad practice? It makes problems harder to debug as you encounter now.
I am using Intellij
to learn JavaEE and in order to view some features when jsp translating into servlet, I also have to find the file.
I didn't find it below <tomcat_home>/work/*
. I finally find that the file is under the ~/.IntelliJIdea15/system/tomcat/
folder( tree structure showing from ~/.IntelliJIdea15/system/tomcat/
)!
Name related to project name |-- conf |-- logs `-- work `-- Catalina `-- localhost `-- projectname and type `-- org `-- apache `-- jsp |-- survey_jsp.class `-- survey_jsp.java <--- here
If you still can't find it under Intellij's home folder, you may have to try using
find . | grep 'nameOfYourJsp_jsp.java'
in suitable parent folder.
