Just turn off the security manager if you are going to allow all 
privilieges.


Having it enabled without any enforcement means you get zero security 
controls and performance penalties all over the place.

Hi,

I am unable to reproduce this with a clean build of the current 9.0.x source.

I built the sample application without configuring the connection to Azure.

Once deployed, it failed with a security permissions error. This has fixed by 
adding the following to the web application permissions:

permission java.util.PropertyPermission "com.ctc.wstx.returnNullForDefaultNamespace", 
"read";

No other changes were made compared to the default.

The index page then showed correctly.

Re: Intermittent ServletException - Unable to compile class for JSP for a struts-1.3.10 web-app with Tomcat 7.0.26/7.0.27

[Konstantin Kolinko]

2012/4/12 Ashima Sharma ashpr...@gmail.com:
 Most of the jsps have this issue...but it happens randomly. For e.g., i wd
 be able to access the registration page 5 times w/o any issue, and the 6th
 time I'd get this error.
 Its bizarre that tomcat tries to recompile the already compiled jsp at some
 random point even though the page hasn't changed, and throws the cannot
 compile error. All the jsps with this issue have the .java and .class files
 under the work directory.

 The compilation issue is
 in org.apache.jasper.runtime.JspSourceDependent.getDependants method for
 every jsp
 in regstration_jsp.java -
 line 49-  public java.util.Mapjava.lang.String,java.lang.Long
 getDependants() {
 line 50-    return _jspx_dependants;
 line 51-  }


 *An error occurred at line: 49 in the generated java file*
 *This method must return a result of type MapString,Long*

What is the type and value of  _jspx_dependants field?

It seems that it complaints that that field returned by the method is
not MapString,Long.

 Can you confirm that after you try to access the .jsp from the
 browser, the timestamp on the .java file changes?

Timestamp does not matter, because in latest Tomcat 7 it is set to
match the original file.

There is a comment at the top of generated java file that mentions
this fact and the actual time of generation.

You can look at creation time of the file as provided by NTFS. That
is because a new file is created and then its modification time is set
to the past.


1. Can you cite with what parameters JspServlet in your web.xml is
configured, exactly?


 This error happens when the original .class file can't be deleted
 before re-naming an SMAP-loaded copy of the .class file. Can you
 confirm that you have files called, for example,
 userProfileBodyTile_jsp.java, userProfileBodyTile_jsp.class, and
 userProfileBodyTile_jsp.javatmp ?

2. It is possible to suppress SMAP generation by setting
suppressSmap parameter in JspServlet to true.

3. Deletion of recently created files on Windows can be impeded by
antivirus scanners. (Subversion client users on Windows are sometimes
complaining about that. It depends on a/v product being used.).

Maybe Tomcat can rename the old file before deleting it.
IIRC Windows allows renaming files that are open for reading, but has
problems with deleting them.


 I read that you have performed a clean install of Tomcat, which is a
good step to take because this looks like a mismatched Jasper problem
or something.

On Windows the actual setting the Service starts with are stored in
the registry. I hope those are correct.  I also hope that you do not
have any strange JARs (e.g. a copy of Jasper) in your webapp.

Best regards,
Konstantin Kolinko

[Ashima Sharma]

Christopher, response to your questions:

[Can you confirm that after you try to access the .jsp from the
browser, the timestamp on the .java file changes?] -* It does not change.
ALL the .java and .class files have the same timestamp as the .jsp files
which is the same as when the war was deployed.*

[Are you deploying from a WAR file or exploded directory? Also, are any
of your JSPs in a .jar file (whether this is in a WAR file or not)?] - *From
a war file. Jsps are not is a jar file. *

*This is a legacy app and has spring + struts...spring is being used for
dependency-injection only, and struts as the web-framework. I should have
mentioned this earlier, but we have other spring based apps (without
struts) on tomcat 7.0.26, and we don't see this issue with those apps. *

[Can you
confirm that you have files called, for example,
userProfileBodyTile_jsp.java, userProfileBodyTile_jsp.class, and
userProfileBodyTile_jsp.javatmp ?]
*The only files that I see under the work directory are .java and .class, I
have not seen any .javatmp files in that directory

*I'll send you registration.jsp and .java files separately. thanks.

But I'll retry that and let you know the outcome.

- We have excluded the tomcat folder from anti-virus scans.

definitely no copy of jasper.

 Timestamp does not matter, because in latest Tomcat 7 it is set to

 this fact and the actual time of generation.

 3. Deletion of recently created files on Windows can be impeded by 
 antivirus scanners. (Subversion client users on Windows are

It's weird that the .classtmp file does not appear to exist, either.

 Maybe Tomcat can rename the old file before deleting it. IIRC
 Windows allows renaming files that are open for reading, but has 
 problems with deleting them.

The code definitely creates the new file, then deletes, then renames.
Since the delete fails, the rename can't occur. Strange thing is that
the file that should be re-named (.classtmp) does not exist according
to OP.

Also, there isn't much in the way of directives in the original JSP.
First, some declarations:

%@ page trimDirectiveWhitespaces=true %
%@ include file=/WEB-INF/pages/taglibs.jsp %

Then after that, it's just using standard JSTL tags. The page looks
fairly clean to me.

If there is A/V in the mix, there might be a problem writing, then
reading, then deleting, then re-naming, etc. all in a short period of
time... it might just be an I/O problem.

Intermittent ServletException - Unable to compile class for JSP for a struts-1.3.10 web-app with Tomcat 7.0.26/7.0.27

[Ashima Sharma]

We just did a tomcat upgrade (from 6.0.36 to 7.0.26) for a legacy
struts-1.3.10 app on Windows 2008 R2 (64-bit).
Ever since, there's been an intermittent occurence of the following 2
exceptions (for random jsps) -

*2012-04-10 18:27:45,751 ERROR [org.apache.struts.tiles.taglib.InsertTag] -
ServletException in '/WEB-INF/pages/registration/registration.jsp': Unable

org.apache.jasper.JasperException: Unable to compile class for JSP
*
*
*
*
*
We don't precompile the jsps. The related jsps already have the
corresponding .java and .class files in the work folder.

Have researched and found a ton of solution for similar issues with earlier
versions of tomcat. Have tried the following plausible solutions:
1. Made sure that the tomcat install was clean, the work folder was deleted
2. Made sure tomcat has full permissions to the appropriate File/Folders
3. Made sure tomcat is running with development=false
4. Tried with JspServlet setting of fork=true and fork=false
5. Made sure that there's no search/indexing services trying to access
tomcat folders creating access conflict
6. Tried going to the latest version of tomcat 7.0.27

The error still persists. Any thoughts/ideas ...
thanks.

So, what's on line 49 in regstration_jsp.java?

The JSP compiler is fairly good at reporting information about the
original JSP source, too. Did it give you any clue what the problem was?

When you say intermittent, do you mean that sometimes the JSP
compiles without a problem and other times it fails? Or, are you
saying that only some of these JSPs have the problem, but it's consistent?

Full stack trace?

Have you tried tracking-down the problem on line 49 of that file?
Maybe your underlying code changed and the JSP needs to be updated?

Are you deploying from a WAR file or exploded directory? Also, are any
of your JSPs in a .jar file (whether this is in a WAR file or not)?

There have been some recent reports of constant recompilation when
JSPs are in ZIP archives (and both .jar and .war are just .zip files
with certain expected entries within them).

 The compilation issue is in
 org.apache.jasper.runtime.JspSourceDependent.getDependants method

Hmm, that looks like Tomcat is not generating good Java code. Would
you be able to post the entire .java file and the original .jsp? I
understand if that's not something you want to post publicly, so you
could email it directly to me if you feel better about that.

I read that you have performed a clean install of Tomcat, which is a

This error happens when the original .class file can't be deleted
before re-naming an SMAP-loaded copy of the .class file. Can you
confirm that you have files called, for example,
userProfileBodyTile_jsp.java, userProfileBodyTile_jsp.class, and
userProfileBodyTile_jsp.javatmp ?

 I did not import any classes.
 
 You must have at least one import to resolve the class Part. Since 
 I'm pretty sure a class with that name was added in servlet 3, 
 wildcard imports are very likely the problem.
 
 I downgraded the Tomcat to Version 6.0.35 and looks to be working 
 correctly now.
 Maybe Serena Dimensions cannot work with that higher version of Tomcat 
 (version 7.0.23)? 
 
 The only files I copied over from the 6.0 version to the 6.0.35 version 
 were the webapps directory the web.xml file and the server.xml file.
 The only difference in the server.xml file between the 2 versions is this:
 
 Listener className=org.apache.catalina.mbeans.ServerLifecycleListener 
 /
  Listener className=org.apache.catalina.core.AprLifecycleListener 
 SSLEngine=on /

So what Mark  are both saying is this: in the JSP there is some code
which imports, via a wildcard, two packages that both contains a Part class.

We are not talking about importing things on the file system.  We are
talking about a specific Java command which is part of the code.  E.g.

If both of the packages below contain a class called Part, then the
compiler can't tell which one you are trying to use.

 import com.examples.stuff.*
 import com.examples.other.*


You can use an editor to look in the the JSP file in question for the
word import somewhere near the top of the file and the '*' character.

If there is more than one '*', you can report the error to Serena
Dimensions or try to fix it yourself.

Error: Unable to compile class for JSP

[Justin Larose]

Well now that I got the certificate setup and users login to the 
application they are not seeing all content...
When they login to the application (Tomcat version 7.0.23) they get the 
error below in the initial splash window. (there should be a menu instead)

If I switch back to the Tomcat 6.0 version it runs fine. I checked the 
.jps files and are identical between the version 6 and version 7 
application.

The error message says you have a bug in the JSP.

The bug appears to be that the Part.class reference is ambiguous.

This means that more than one Part.class reference is visible in the
scope of the JSP, possibly via an import statement inside the JSP.

Can you examine the JSP code?

1. If you are using precompiled jsp or tag files, you should compile
them with exact the same x.y.z version of Tomcat where you deploy
them.

2. Stop Tomcat and clear everything from the /work subdirectory of
CATALINA_BASE. That is, there might be *.class files compiled with
some other version of Tomcat.

It's a known bug, which has beend discussed on the developers list only 
very recently. See

Your workaround (using ant 1.5) seems fine. The final solution is still

4.1.38. This still needs some clarification though.

Unable to compile class for JSP

[Gaurav Kushwaha]

Hi,
I am getting Unable to compile class for JSP error in one of my JSPs
which was working perfectly until 2 days back. It says:

An error occurred at line: 10 in the jsp file: /WEB-INF/jsps/Listing.jsp
String perspective = null;
  ^
   This jsp is being included in another JSP and that is the one i am
trying to access. The strange part is that I have Listing.jsp included in
few other JSPs as well but those are working fine.

Any help would be appreciated.

I am using Idea. Even that has an option to compile the jsps though. I will
try that. What exactly do you mean by including libraries ? Are you
referring to class imports ?

Re: Unable to compile class for JSP

[org]

Hi Peter,
I probably got the wrong end of the stick, missed the thread etc, but its 
seems like you going through a whole lot of pain so I was wondering.


If you have a servlet and a bunch of JSP pages, did you know that the JSP's 
will not compile when you Clean and Build in Netbeans.
If you right click on the project name and under the compile section ask it 
to--- then it will. Or if you compile each JSP file then it will to.
So its possible that its just an error in the JSP that goes undetected until 
the browser hit it.


Try set it up so that it compiles all the JSP's and I have a feeeling you 
will see it at design time.

Dont think its a bug in tomcat good luck.

Hi everybody,
thanks for your help, which I really appreciate!
I still don't know exactly what it was, but I fixed it by doing the
following:

- uninstall tomcat
- reinstall it, not having it run as a windows service
- installing it in a directory tomcat_4_1 rather then the suggested
tomcat 4.1 because I hade problems with spaces in path before. Now it
works!

Bye
Peter

Hi,

This might be a silly question, but it seems to be quite a common
problem (lots or links in google). But none of the offered solutions so
far worked.

So I am asking the people who probably know!

RE: Unable to compile class for JSP

doesn't seem like much to go onwhich example did you use and did you look 
in the work folder to see what the compiled servlets were referring to?

Hi Peter,
did you check that the JAVA_HOME enviroment variable is properly setted?
Since JSP are compiled in java classe the first time if Tomcat cannot
compile it is maybe coz it dosen't find the JDK.

Re: Unable to compile class for JSP

[Martin Gainty]

Peter

jasper errors means your (index.)jsp is incorrectly compiled or your 
jspcompiler is incorrect or does not have permissions to compile

If you look at $TOMCAT_HOME/conf/catalina.properties you should see these 
grants to the jasper compiler package 

package.access=sun.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.,sun.beans.
package.definition=sun.,java.,org.apache.catalina.,org.apache.coyote.,org.apache.tomcat.,org.apache.jasper.

Note the trailing . at the end of the package

and in $TOMCAT_HOME/conf/catalina.policy you should see these grants
try
{
// Precompiled JSPs need access to this package.
permission java.lang.RuntimePermission 
accessClassInPackage.org.apache.jasper.runtime;
permission java.lang.RuntimePermission 
accessClassInPackage.org.apache.jasper.runtime.*;

};

The error report implies that it's trying to compile a jsp it can't read 
(line -1 and jsp file: null).  Can you check for a root cause in the 
logs relating to the stack trace below?  Also check the usual suspects 
-- file permissions, security manager, etc.

RE: Unable to compile class for JSP

[Abdelmonaam Kallali]

Hi 
I'm not that professional
But what I did and it worked is:
Let's say we have jsp file called myJsp.jsp in ROOT and a java program
myProgram.java 
1-Compile myProgram.java in a package named myPackage In WEB-INF/classes.
2-import that package in myJsp.jsp like this %@ page import=myPackage.*%
(put it in the first line of the file)
3-somewhere in myJsp.jsp create an instance of myProgram 
myProgram prog =new myProgram ();
then use it as in java

Have you taken a look at the full stack trace of the root cause in the 
logs?  It would also be helpful if we could see the relevant jsp source 
and know which version of tomcat you are working with.

Unable to compile class for JSP

[edward]

Hi,

I'm having a newbie type of problem with getting a JSP to compile.  Seems it 
can't find my class.

Rest of error messages:
Generated servlet error:
The import FOO cannot be resolved


Following files are located in Tomcat/webapps/VIP
Code:
Home.jsp
%@ page import=java.util.* %

html
body
br
h2 align=centerHome Page/h2
pnbsp;/p
jsp:include page=DisplBar.jsp flush=true/
pinput type=submit value=submit/p
/body
/html

DisplBar.jsp
jsp:directive.page import=java.util.*/
jsp:directive.page import=FOO/   // have also tried FOO.*
.
.
.
foo.bar();
.
.
.

I have copies of the complied class foo.class in Tomcat/webapps/VIP, in 
Tomcat/webapps/VIP/WEB-INF, and in Tomcat/webapps/VIP/WEB-INF/classes.

Class foo is in the default package.

Beside using the default package, what am I doing wrong?  Thanks.

Ed

Since you seem to be aware the using the default package is not allowed,
why haven't you fixed that first?

Well, umm, actually I wasn't aware that the default package isn't allowed.  I 
just considered it poor practice to use.  Let me go fix that.  Thanks.

Quoting from section 11.2 of the JSP spec:

However, as of JDK 1.4, importing classes from the unnamed package is
not valid (see http://java.sun.com/j2se/1.4/compatibility.html#source
for details).

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

Hi all!
I used to work with Tomcat 3.3 but recently I decided to change to Tomcat
5.5
Unfortunately it appears that I cannot run most of my .jsp files on this
version of the server because I encouter this problem:
When the server tries to compile the jsp`s, it shows me an error with this
stack trace :

However, when I convert the same files to applets, this problem doesn`t
exist anymore.

I use Java 1.5 and my OS is Windows XP

Does anybody have any idea of what might that mean?

Thanx in advance!
