Not able to compile servlet

Hello
I would like some one to help me.

Could you please guide me about what more has to be done so that The servlet can compile.
Thanking you

Not able to compile wrapped package bodies.

Hi All
Can anybody pls help me finding me the reason why I m not able to compile .plb (wrapped package body). There are no compilation errors. But when I run the .plb file (as @xyz.plb), sqlplus window hangs. No error shown. Everytime I had to close the window after waiting for 8-10 minutes.
This is happening only with 11 files out of 200.Rest were compiled.
Any ideas? Do we have any other way to wrap than using pl/sql wrap utility or pl/sql plug-in for wrapping(which is actually the same as former)??
ThanksInAdvance!!
Keep striking the iron until it's hot!

yes, I did check for locks from pl/sql developer only. No Locks.
I waited for 10 minutes for a 6 kb .plb file to get compiled. But had to close the session after that.
I am using oracle 10g, pl/sql developer 7.1.0.1337
sql*plus Release 10.2.0.2.0

Not Able to Compile Java code

Hi Java Gurus
I am not able to compile this code Pl help
class For {
public static void main (String [] args) {
int I = 0;
show:
     if (I < 2) {
System.out.print("I is " + I);
I++;
continue show;
}

class For {
public static void main (String [] args) {
      for(int i = 0; i < 2; i++){
              System.out.print("I is " + i);
}this does the same as your program: the for loop is the best for this, but i agree with the others read some tutorials on loops in java. As posted before java has no concept of the GoTo syntax, loops or recursion are your only options

I am not able to compile forms and my form application is close

Hi All,
There is strange problem arising in my system. I am not able compile the forms from my machine.MY machine is having Vista as OS and I have installed the latest 10g release of forms (the vista compaitable version). Also I am not able to open any of the existing and developed forms for one One Oracle Retail product. The existing forms were build on 10g version 2. (10.0.2). But when I am trying to open the forms, the application hangs immediately and then its says explorer is closing, the program has some problems. The same error comes in both the cases.
Thanks & Regards,
Debabrata

Debabrata,
First You must read this topic from Steve Cosner:
Forms 10g installed and running on Windows Vista
After You must to install Forms 10g under Window Vista following the instruction in the topic.
At this time Form Builder work fine; but the Compiler called from Framework return errors and the program hang.
I have tried to run frmcmp.exe outside the Form Builder and the program newly abort.
I have sended my Form to Steve Cosner and I attend a reply.
Bye

OCI demos-not able to compile on red hat Linux

Can anyone narrate how can I get the OCI routines (demo) working.
I feel that they are failing to run. what are the check points needed
that I should verify that an OCI program executes.
Does this needs any special settings or running any script files
before hand?.
I am running on Red hat 6.1 and Oracle 8.1.6 based on Linux.
when I detected the installations, following program folders are
missing
1. plsql/public
2. lib/libextp.a
I used one of the porgrams in the sample oci13.c and changed the user
account and password. I then compiled as follows
gcc -I(include files) -c oci13new.c
But after this it gave me successfully the object file. But I could not
able to link this to produce any a.out file!.
Can anyone suggest how can I do this?
Nat

Step 1) is needed, you cannot got directly from 8.1.5 to 10g.
When you are on level 8.1.7.4 (Step 2)) there are alternatives to export/import, for example DBUA. But first, you are right, you have to build up a 8.1.7.4 database on Linux, because this release does not allow other methods of transportation across different platforms. Or you import directly into a new built database on Linux.
For database upgrade see
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14238/preup.htm#sthref52
Step 3) is described step-by-step here:

Hello
I would suggest using an IDE for writing the code (like eclipse maybe) and testing it on Sun's Wireless Toolkit which comes already with all the needed libraries.
Of course you can find all this information by searching google..

Hi,
I have tried it, by inserting it before the form compilation code the echo command works , but then while compilation it gives me an error as file not found . This file XXIB_I10_BA_BALEVEL.fmb is existing in the given path . Is it a problem with the userid being given so. As i am able to compile the file individually(During individual compilation i have hard coded the username and password), not through a installlation file . Have even checked the FORMS_PATH even thats right .
Command used in installation file :
# +======================================================================+
echo "------------------------------- " | tee -a $LOG_FILE
echo "Generating Forms in English ... " | tee -a $LOG_FILE
echo "------------------------------- \n" | tee -a $LOG_FILE

i have one folder "C:\Program Files\Apache Tomcat 4.0\org\apache\commons\logging" containing some LogFactory calsses but i dont know where to put this folder so that tomcat can find them.
please help me..
i know i may not be clear to u but plz give me some way out i m totally stucked.
manish

hi,
thanx for your reply.
ya i have "commons-logging-1.0.2.jar" file but when i tried to put it with other jar files and set the class path and run the application thru tomcat then it automatically stops the tomact.and when i removed this perticular logging jar file then tomcat works normally but gives the error which i mentioned before.
i have also tried the second option u suggested, by putting the LogFactory class files in "C:\Program Files\Apache Tomcat 4.0\webapps\examples\WEB-INF\classes\org\apache\commons\logging" but that was not working.shud i set some classpath for them? or shud i have to import these packages........ but when i copied this folder "org" to C:\Program Files\Apache Tomcat 4.0\webapps\examples\WEB-INF\classes and in program wrote import org.* then copilation error occured "no such package found.
what to do now.

J2EE app server not able to compile JSP

Hi,
I have just installed J2EE app server and am trying to deploy a JSP. The following error is generated. can anyone help me please.
Thank you,
Deepika.
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.

This is a known issue.
Here's an explanation of the behaviour you are seeing:
The misleading error message is printed only in the case where a javac
compilation error line number cannot be mapped back to a line number
in the JSP source code.
The internal representation of a JSP element ("JSP node") in the JSP compiler
contains the following info:
- The begin line number of the JSP element in the JSP page
- The begin and end line numbers ("range") of the Java code that was
generated for the JSP element
When attempting to map a javac error line number back to the JSP
source line, we determine the range into which the javac error line
number falls, and retrieve the JSP source number of the JSP element
associated with that range.
However, in some cases, it is impossible to trace a javac error line
number back to the JSP element that caused the error. For example,
consider the following scriptlet:
<%
String query = request.getParameter("query");
if(query != null) {
out.println(query);
} else {
out.println("(null)");
// } // <-- !Missing brace syntax error
%>
Since the JSP compiler wraps the generated code into a
try-catch-finally block, the above syntax error in the scriptlet
causes havoc with that try-catch-finally block, and results in 3 javac
errors:
<file>jsp.java:<line1>: 'catch' without 'try'
} catch (Throwable t) {
^
<file>jsp.java:<line2>: 'try' without 'catch' or 'finally'
try {
^
<file>jsp.java:<line3>: '}' expected
Notice that all of the above javac error numbers are outside the range
of the java line numbers corresponding to the scriptlet that caused the
error, and therefore cannot be mapped back to any line numbers in the
JSP page source.
AS 8.0 PE does not handle this case correctly, and prints out the
misleading error message (though the real error message can be found
in the server log).
Notice that this problem is going to be fixed in AS 8.1, so that if a
javac error line number cannot be mapped back to a JSP page line
number, the javac error is still returned to the client.
In AS 8.0 PE, you need to check your server log to find out why the compilation failed.
If you still have any problems, send me your JSP, and I will take a look at it.
Thanks,
Jan
