anybody can please help me with this error?
Thanks

Your stack trace indicates classes that are not part of Sun ONE Web Server 6.1 (e.g. com.iplanet.server.http.servlet.NSServletEntity) but are classes in earlier releases of the web server. It looks like your web application contains classes or .jar files that contain an older implementation of the JSP engine from a previous web server release. Remove these and give it another try.

hi,
when i use the code
if(st != null)st.close();
if(con != null ) con.close();
that works good ,the old error has been corrected.
but it's now throwing an SQLException[b] "datasource name not found and default driver not specified" why this occurs and also can u give me the explanation for the old error????
I am sure that i have created an user DSN, i am 100% sure about it .even though there is an error.

What is your jsp doing at this point?
Can you debug it?
Put a few System.out.println() statements through so you can see at which line it breaks.
At a guess, seeing as you have mentioned databases, it will probably be related to some database configuration you have done on your local system but not on the server. JNDI setup? Permissions?

Org.apache.jasper.JasperException: Error: Attempt to clear a buffer that's

Hi,
All I am trying to do is execute a <jsp:forward page=""/> commend. The page I am refering to does exists and three other pages that have the same commend are able to forward to the said page with little issue. All the pages are in the same directory and the path indicator to them is correct. Any help in this matter will be highly appreciated.

jsp:forward always flushes the buffer before proceeding.
Do you have a statement in your jsp like out.flush() before your use jsp:forward? If you do, try removing it

Error on Import Roles Tab (org.apache.jasper.jasperexception)

Hi all,
We have installed Edge Standard with SAP IK and create systems for SAP. When I switch over to Import Roles tab, following error is fired:
org.apache.jasper.jasperexception
We have copied the relevant JCo sapJCo 2.1.8 files in relevant directories, still the error persist.
Please advise.
Regards.

Hi Ingo,
Yes, it's tomcat running on Oracle.
However, the issue is now resolved after installing oracle patch. However, it took us re-installation of oracle since previous oracle installation didn't support the (x86) path, subsequently BOE was also reinstalled along with SAP IK. The issue disappeared this time.
Regards.
Mohammad

Org.apache.jasper.JasperException error

Ok here is the problem. I have this war file that works great on my development environment, but when I move it to our QA environment I get the following error:

Is there a difference in environment between the machines?
Version of java?
Version of Tomcat?
Operating System?
This error is normally generated when
1 - the class file is invalid
2 - the bean does not have a PUBLIC no-args constructor
Are there any libraries that this class would depend on that are on your machine, and not on the the QA machine?

Org.apache.jasper.JasperException Ambigous Class Error

I included two classes:
<% @page import = "com.myco.ejb.ThisBean" %>
<% @page import = "com.myco.ejb.session.ThisBean" %>
and received an org.apache.jasper.JasperException Ambigous Class Error on the second import. One is a cmp bean, the other is a session bean. I thought Sun wanted us to name our packages like this to aid in the prevention of duplicate class names (i.e., Windoz DLLitus). Shouldn't these classes be unique by the package name?

No, that's not redundancy. Are you using the fully qualified class name in your jsp:usebean tags?
like:
classname="com.mypackage.mybeans.MyBean"
And are you using the package statement properly in your source?
In the case that you are using two classes of the same name in one file the compiler has to have a means of distinguishing between the two. The only way for it to do so is to use the fully qualified name of the class in each case in which it is referenced. This means either in the jsp:usebean tag as shown above, or in such a case as:
com.mypackage.myclasses.MyClass theOb=new com.mypackage.myclasses.MyClass();
Awkward yes, but ambiguous No.
In the case where you are using only one class of a given name the import statement will be sufficient for the compiler to know that it is that which you fully qualify in the import statement.
Remember, all that the import statement does is provide the convenience of pre-clarifying exactly which class you'll be referring to when using the abbreviated class name only. Importing two classes of the same name defeats the purpose.
Good luck,
Brad

Error org.apache.jasper.JasperException: null

Hello,
I am working with an application trying to execute something in a JSP (or servlet too, getting the same error) and at the time the JSP finish all the work and try to redirect the response, I got the error below.
Please any idea would be very, very, helpful.
The code executed is:
request.getRequestDispatcher("/ThresholdsTransactions.jsp").forward(request,response);The page ThresholdsTransactions.jsp exist, is the source where I call the page that give me the error.
The error is:

java.lang.Integer.parseInt(Integer.java:436)It certainly appears that you're using Integer.parseInt somewhere, if you're not, then maybe a call you're making is. Maybe use some SOP's to try and trace the line at which this is occuring?

Its like this.. after you dispatch the request by the method call [callWeb...], the dispatcher would dispatch the request to that page and after the page is dispatched and response has been sent, the execution continues on this JSP, ie from the line after the call to the [callWeb..] function.. All you need to do to avoid this exception is,
a) put a return; statement after the call to the function.
Or
b) structure your code in such a way that after the call to the [callWeb..] function, the execution would not continue;
I would prefer the first condition though along with structuring the code in such a way that you need not have that many calls to the function. Instead have a String dest variable, which would change and make a call in the end

I got org.apache.jasper.JasperException:quote symbol expected error

Hi Proffesionals
iam new working with spring

org.apache.jasper.JasperException:/WEB-INF/showjsps/showmsg.jsp(3,28)quote symbol expected error
how can i handle this error
any one can help me please

Hi dvohra,
Thanks for ur reply.
I guess my problem has got to do more with the oracle error-
ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], [], [], [], [], []
I believe jasper is just throwing the exception caught from oracle error. Please let me know if u think otherwise.
Can you help me in handling this ORA-0600 with the above mentioned arguments.
I basically, would like to know in which directory the JDBC driver go, if i use tomcat4 server and do I have to set the system classpathand PATH for the driver location.
Also which driver should I use to connect to remote DB- Oracle 9.2.0.5.0 (I have Ora 8i in my local machine) when using JDK1.4. (SHOULD I ALSO HAVE THE OTHER JAR files LIKE THE "CHARSET" IN THE LOCATION WHERE THE MAIN DRIVER FILE IS STORED.)
Thanks,
Karthik.

Org.apache.jasper.JasperException; JCO error when Importing SAP Roles in C

Hello experts,
I have installed BOXI 3.1 SP3, Integration kit SP2, BW/BI 7.0 and ECC 6.0 on Windows 2008/64bit.
My goal is to import the roles into CMS from SAP BW/BI but getting the follwoing errors:
JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc
C:\Windows\SysWOW64\sapjcorfc.dll: Can't load AMD 64-bit .dll on a IA 32-bit platform.
java.library.path [C:\Windows\SysWOW64\;D:\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\]
org.apache.jasper.JasperException
I followed the note 1292144 - JCO error when Importing SAP Roles in CMC,but unfortunately without success.
I installed SAP JCo Release 2.1.9 (64bit)
Best regards
Lutz

Install the 32bit version of the Java connector. BOBJ is 32bit so even on 64bit Windows you need the 32bit version of the Java Connector.
