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

[aiye4686]

Heh, just in case anyone is ever as stupid as me in teh future:

I realised that I had put catalina-ant.jar into my TOMCAT_HOME\common\lib
directory, as well as my WEB-INF\lib directory... I have no idea why I did
that, but blame youthful stupidity.

Somehow, having catalina-ant.jar in the common\lib directory really messes
with tool.jar - why I don't know.

Anyway, removing the catalina-ant.jar from the conf\lib dir solves
everything!

Cheers
Andrew


Quoting [EMAIL PROTECTED]:

 Hi, and thanks for reading this query - it isn't (at least to me)
 anything
 to do with putting tools.jar into web-inf/lib, or anywhere else, for that
 matter.

 Here is the problem:

  2004-05-22 02:25:00 StandardWrapperValve[jsp]: Servlet.service() for
 servlet jsp threw exception
 org.apache.jasper.JasperException: Unable to compile class for JSP

 No Java compiler was found to compile the generated source for the JSP.
 This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar
 from the JDK
 to the common/lib directory of the Tomcat server, followed by a Tomcat
 restart.
 If using an alternate Java compiler, please check its installation and
 access path.

 I am doing a thesis involving using tomcat+hibernate+mysql to create a
 web-site that auto-marks web applications.

 Using Tomcat ver. 5.

 Until yesterday I could fire up tomcat, run my code, make changes to .jsp
 and .java files and, without restarting tomcat, see the changes. Yes,
 tools.jar, and in fact ALL the necessary jar files for rinning my app are
 in the right place. The application has been running smoothly for about 2
 months now.

 Today I began to use ant (in a java file - by importing

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

[Derek Mahar]

Did you put your class in package?  Unless you put your classes (even
those in a jar file) in a package, Tomcat assumes a default package of
"org.apache.jsp".  If you did not put your class in that package, Tomcat
won't find it.  See
http://marc.theaimsgroup.com/?l=tomcat-user&m=102997632829655&w=2.

Re: "org.apache.jasper.JasperException: Unable to compile class for JSP" errorsafter switching from Tomcat 4.1.18LE to 4.1.27

[Joe_Rattz]

Ok, I tried jdk1.4.2_01, but it does not fix the problem.  So, I backed up 
to jdk1.4.1_03 which does not have an issue like the one below.

Thanks everyone.

Ooops, ok I had one other 'significant' change that I failed to mention. I 

had also upgraded to jdk1.4.2 from 1.4.1_03.  I thought in my testing I 
had eliminated that possibility, but I was wrong.  It looks like there is 
a bug in jdk1.4.2 that is causing my problem.  I am basing that on the 
following message:

http://forum.java.sun.com/thread.jsp?forum=136&thread=429766&tstart=0&trange=15


His usage is different than mine, but it looks like the ultimate problem 
and cause were the same, the compiler could not compile classes containing 

inner classes in some circumstances.  So, I uninstalled Tomcat 4.1.27, 
changed my JAVA_HOME back to jdk 1.4.1_03 and reinstalled Tomcat 4.1.27 
and everything is working fine again.

Tuesday I am going to try the new jdk1.4.2_01 and see if the bug still 
exists in it.  I'll post back afterwards with an update.

Thanks.

Open up the generated Java file, but I believe that you will see
some extra stuff before the imports from something at the top of your JSP
file that shouldn't be there.

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

[guyr]

Since you didn't provide a fully qualified class name, Tomcat defaulted to
looking in the current directory, relative to /examples.  So it was looking
for jsp/dates/DbWriter.class.  Where are you keeping your class?  Is it in
the classpath?

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


Hi,

 I have a simple server-side java class named DBWriter (with no package
name)
I am using it in a jsp file like this

 <%DBWriter dbwrt = new DBWriter()%>

 I get following exception on browser page while browsing the above jsp



 _
 Error: 500
 Location: /examples/jsp/dates/mydate.jsp
 Internal Servlet Error:

 as I told earlier the class I am using is not residing in any package,
while
 tomcat is trying to find it in jsp.dates package.

 How do I get around this problem ? Is this a bug since I see similar kinds
 of problems reported on the mailing list archieve

 your help is appriciated,
 Mandar
