Problem in compiling packages

I am new to Java. I am currently using Java in developing a simple system. However, my system need to import other external classes.
The main problem is i dont know how to compile this file when they are in separate folder (i am using windows). Let say the main .java is in one folder and other external .java in other folders. I knew this can be done with the use of package. the problem is when i try to compile, there is a problem.
I used to refer from the below link for many times, but still cannot get it.
http://java.sun.com/j2se/1.3/docs/tooldocs/win32/javac.html
can anyone provide me the most simple way of:
1. import from external classes into my main system
e.g: import com.jrefinery.report.Element;
2. how to compile all .java from different directory
3. after i compile, i need the .class files place in other directory
advanced thanks to those who able to provide help.

Here's what I would do.
1. Create a directory to hold my packaged classes. For example c:\myjava\classes.
2. Create another directory to hold my source code. For example c:\myjava\source\project1. If you want to divide up the source code into multiple directories, that's ok.
3. Before compiling, "cd c:\myjava\source"
4. Compile with "javac -classpath c:\myjava\classes -d c:\myjava\classes project1\*.java project1\dir1\*.java" (This command assumes some of your .java files are in the dir1 directory.)
The -d options means put the packaged classes into this directory. It will create directories as needed in the classes directory. For example com\jrefinery.

Compiling packages

Hi all,
I have problem on compiling packages.
Here is the structure of the directory
1:path is c:\java
2:Created a directory inside java folder called test1 as parent directory,then I created a new folder calledd test2 inside the test1.(c:\java\test1\test2).
3. I have created java class called House.java in which I have declared a package
package test1.test2;4.I have created the main class HouseMain.java with
code]package test1.test2;
5.I have copied all the java class in the folder test2.
I cant get it compiled even after setting the classpath.
Can anyone help me please how to compile ?.
Thank you

Thank youTry this:
Navigate to c:\java and type exactly this:
javac -classpath . -d . test1\test2\*.javaNote the "dot" after both -classpath and -d. Read the javac docs to make sure you understand what those mean.
You should see all the .class files in the same directory as your .java files. (Not the best idea, but easy for now.)
To run, type this:
java -classpath . test1.test2.HouseMain%

That's strange... it wasn't installed.. although I had never,ever faced a problem while compiling packages via AUR.. maybe, I should be careful when uninstalling orphans.. thanks for the help..

Having problem with javax packages

i had problem with compiling my program which is java servlet, and it is complaining that it does exist javax servlet * package , how can i solve this problem?

I don't think servlets come with the standard packages. You have to find it somewhere else. I think you can try J2EE API. There in beta version for 1.3. Should be ok though. Hopefully it will fit right into 1.4.

Execution of Immediate SQL in compiled package in two versions of SQL*PLUS

A peculiar problem has risen in our database.
Execution of Immediate SQL in compiled package in two versions of SQLPLUS gives different results
We have a compiled package with two procedures that contain immediate SQL statements, and these are:
+PROC_DELETE_ROWS+
+     -- This immediate sql deletes unreferenced Document Types from the DOC_REF_TYPE table+
+     delete from doc_ref_type t where exists (select 1 from PROARC_DOC_REF_TYPE_VW d where d.doc_ref_type = t.doc_ref_type)+
   +     and not exists (select 1 from doc_ref d where d.doc_ref_type = t.doc_ref_type)+
   +     and doc_ref_type not in (select doc_ref_type from eis_doc_ref_type)+
   +     and doc_ref_type not in (select eis_doc_ref_type from eis_doc_ref_type)+
+PROC_ADD_NEW_ROWS+
+     -- Drop the temporary table+
+     drop table TMP_PROARC_DOC_REF_TYPE+
+     -- Create a temporary table+
+     create table tmp_PROARC_DOC_REF_TYPE as+
+     select DOC_REF_TYPE, substr(DOC_REF_TYPE_DESC,1,100) as DOC_REF_TYPE_DESC+
+     from PROARC_DOC_REF_TYPE_VW+
+     -- Insert document types that do not exist in the DOC_REF_TYPE table+
+     insert into doc_ref_type t (DOC_REF_TYPE, DOC_REF_TYPE_DESC)+
        +     select distinct DOC_REF_TYPE, DOC_REF_TYPE_DESC from tmp_PROARC_DOC_REF_TYPE s+
        +     where not exists (select 1 from doc_ref_type t where t.doc_ref_type = s.doc_ref_type)+
I am using the following test script:
+Exec mypackage.proc_delete_rows;+
+Commit;+
+Select count(*) from DOC_REF_TYPES;+
+Exec mypackage.proc_add_new_rows;+
+Commit;+
+Select count(*) from DOC_REF_TYPES;+We have a Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit
I am using SQL*Plus: Release 8.1.7.0.0
The test script is working as expected.
Count after delete =155
Count after insert = 511
but when I use another computer with SQL*Plus: Release 10.x
The Test script returns the following
Count after delete =155
Count after insert =155
The same is happening when I am running the scripts as a scheduled job.
QUESTION:
I believe I have found a fix for the problem though. By changing tmp_PROARC_DOC_REF_TYPE in the insert statement to all upper case, the script is running in both environments apparently. But how is this possible? I am executing a compiled package in the database. The session shell should have no impact on the behaveour of the procedure I am calling. What causes this?
Edited by: Reon on Jun 16, 2011 4:44 AM

1) I am using the same user (PANDORA)
2) (PANDORA) for both
3) I am actually not handling any errors. Just skipping any error altogether. I'll check to see what exceptions are raised, and come back.
I have also noticed that SQL/PLUS is not the culprit here. If I use SQLTools 1.5 to run the script, the same thing happens. So it has to do something with the connection or session environment that is inheritet to both clients.

New programmer- how do i compile package members?

im learning java using sams teach yourself java in 21 days. its really good compared to other ive tried but i was having a problem on day 6. i couldnt compile package members successfully. i didnt undestand the book instruction so instead of compiling this way:
C:\noam\java> c:\java\jdk1.5.0_06\bin\javac classname.java
i did it this way:
C:\java\noam\org\cadenhead\ecommerce> c:\java\jdk1.5.0_06\bin\javac classname.java
this worked but other classes inside the package could not recognize this class, though classes outside the package could.
how do i compile package members?
thnx!

I solved the problem...! I have no idea how but it worked this time!
thnx anyway for everybody who tried to help!

Silly problem when compiling main class

hi there,
i have a problem when compiling the main class.
the classes used by the main class are not recognized. the compiler can't locate the children classes.
i've already set the path and classpath environment variables, but there's still something missing.
how should i organize my folders in order to be able to compile the main class successfully, please?
thanks.

It would be good to have a precise problem description: the actual command used, folder structure and environment variable settings. Even if you have to construct a simple test case with a couple of classes that illustrates the problem.
In the absence of that some generic remarks:
The PATH variable typically points at all the folders that contain executable files that you use often. You can always access other executable files by specifying there full names.
The CLASSPATH variable is typically left unset.
When you use the java tools (like the javac compiler or the java runtime) you can specify the classpath that you want to use with -cp. This will override any CLASSPATH value. So in the simple case of two classes (Main and MyClass), you can put them in anywhere you like (for example C:\MyJavaStuff) and compile and run with:
{noformat}
C:\MyJavaStuff> javac -cp . *.java
C:\MyJavaStuff> java -cp . Main
{noformat}(Mind the dot after -cp))
By a "main" class I guess you mean a class with a static void main(String args[]) method, but I am suspicious of your "child" classes. Perhaps packages are involved. A precise description of the problem would help.

30EA1: PLS-00172 when compiling package body

Hi there,
I'm having a strange bug when compiling a package body in SQL Developer 3.0 EA1, while the same package body compiles well in production version (2.1).
The error code returned is Error: ORA-06550: line 1, column 64: PLS-00172: string literal too long
Does anyone have the same problems?

yes: SQL*Developer 3EA1 - Not Compiling package Body

PLS-00801: Internal Error - Compiling Package in JDeveloper

I am trying to compile a package in JDeveloper so that I will be able to debug it. The issue is that the whenever I compile it I get a back an PLS-00801: Internal Error.
What is really strange is that when I compile it using sqlplus - the package comes back fine without any problems.
The package is approximately 5400 lines, contains UTF8 characters (I turned on UTF8 encoding in order to get the package to show correctly [found that one on this site - thank you]). It contains approx 15 methods, lost of cursors, ...
I am using the following version of JDeveloper.
Version 9.0.4.0 (Build 1419)
Oracle IDE: 9.0.4.13.2
UML Modelers Vers: 9.0.4.12.69
JMIG Framework: 9.0.4.3.75
SCM Support Version: 9.0.4.12.69
Business Components: 9.0.4.13.79
Java Version: 1.4.2_03
Java Home: c:\Programs\JDev9i\jdk\jre
Any help would be greatly appreciated - even pointing me in the direction of the logs to see if I can track down why I am getting this error.
Thank you
Marc Padberg

Okay -
I broke down the PL/SQL package and figured out what was causing the internal error - it was a parameter that was based on ROWTYPE of a cursor.
Whenever I have a CURSOR%ROWTYPE as a parameter I get an internal error in JDeveloper.
Any help to resolve this would be greatly appreciated.
I wrote a small sample package using dual that simulates this.
CREATE OR REPLACE PACKAGE sample_problem IS
PROCEDURE call_internal_method;
END sample_problem;
CREATE OR REPLACE PACKAGE BODY sample_problem IS
CURSOR get_data IS
SELECT 'Test' as NAME FROM dual;
-- I have to comment this method out
-- in order to compile in JDeveloper
PROCEDURE internal_method_with(p_rec get_data%ROWTYPE)
IS
BEGIN
DBMS_OUTPUT.put_line(p_rec.NAME);
END internal_method_with;
PROCEDURE internal_method_without
IS
BEGIN
DBMS_OUTPUT.put_line('No Rowtype Passed');
END internal_method_without;

try saving your fla and the published files to a new directory and see if the error resolves.

Problem Running SSIS Package with a SQL Server Agent

SQL Server: SQL Server 2012
VS: Visual Studio 2012
Hello,
      I have been having a problem running SSIS packages by using a SQL Server Agent job. I first created these SSIS packages in a separate IS project in Visual Studio. I imported the packages to the Integration Services (Package
Store) instance on my SQL Server and tried to create a job that would run them from there.
      At first I read around about needing a proxy account to allow the agent/packages to access the file system since these packages are importing data from a flat file in the SQL database. So I created a temporary admin user to
use as the user for the agent. I did this by going to Services.msc on the server and linked the account the agent's "logon as". Then arose another issue where I am getting an error about using the incorrect type for my connection managers.
The connection manager "TestFile" is an incorrect type. The type required is "OLEDB". The type available to the component is "FLATFILE". Source: Data Flow Task Flat File Destination [2]     Description:
Cannot open the datafile "O:\*****\Success.txt"
I am not sure what this even means as I am getting this error even with a test package that doesn't do anything with the database. I have just two flat file connection managers in this test project one for grabbing the source file and one for
creating the new test file.
I am not sure what to do.
Thanks in advance,
Matt

then it will covert into "aman.class" file but it creates one more file like "aman1$.class" ..plz help me to get out of this problem..coz its increase my j2me file size..
thanks

That is an inner class in aman.java that you are seeing there.
If you use inner anonymous classes, for example;
public class MyMIDlet extends MIDlet {
   // code for the MIDlet
   // Anonymous inner class
   setCommandListener(new CommandListener() {
      public void commandAction(Command c, Displayable d) {
        // implementation;
        // may access MyMIDlet's private fields
}then the command listener you create will become another class named MyMIDlet$1.class.
In this example you can get rid of the inner class by making one of the existing classes implement that CommandListener interface:
public class MyMIDlet extends MIDlet implmements CommandListener {
   public void commandAction(Command c, Displayable d) {
     // implementation;
     // may access MyMIDlet's private fields
   // code for the MIDlet
   // Instead of the anonymous inner class, we can now use MyMIDlet since it
   // implements CommandListener
   setCommandListener(this);
   // etc. etc. etc.
}shmoove

Problem in importing package

i am new to java and facing problems in importing package which are self made.
secondly does JDK 1.1.3 can support swing

Hi,
I had some problems myself. I will add few lines, maybe it helps:
OK, let's assume that you work in a directory. In this case, set classpath to this hierarchy as well as to "." ('this' hierarchy - like in DOS).
Now, assume that you want to use packages MyPack1 and MyPack2. The source files of classes belonging to MyPack1 must:
- start with command
package MyPack1;
- be located all in the directory MyPack1
(and the same for MyPack2, of course)
If you want to use MyPack1 within MyPack2, you have to include:
import MyPack1.*;
even though MyPack1 is, in fact, located on path: ../MyPack1/*
(trust the classpath is important here)
