JSP'S and Packages!!!!

I'm developing a Web application using Java and Oracle. The system administrator has set up a development instance on Websphere (I don't have admin rights to this server) called MEDS for my projecct. The directory where my jsp files are is: MEDS/MEDS.war/jsp/...jsp files. My Servlet files are in the following directory: MEDS/MEDS.war/WEB-INF/classes. I want to put my database connection string into 1 servlet file, create a package, and then include my servlets and jsp's into that package.
How can I create a package, let's say MEDSPACKAGE, and include my jsp files and servlets in that package? After I've created that package, what statement do I use in each of my jsp pages to include them in that package that I create?
Thank you in advance!!!!

There are also tools that will make this easier for you (such as your IDE or Ant, but each will have a learning curve associated with them. Please, PLEASE take the time to read about the basics in the previous link I posted. You (and your admin) will thank you. :o)

Java-JSP working with packages and classes

Hi everybody,
I'm bearly new on Java-JSP developping and I wanted to know how Tomcat (for example) manage the imported packages and classes.
The fact is I'm working on a project ('/bob') which use some packages that I don't see in the '/bob' directory. So, is that possible that '/bob' is downloading packages and classes from Internet to '/bob/download' virtual repertory and use it? If it is true, is it possible to override this download by making '/bob' project using local packages or classes (example : com.boblibrary.classes.util in '/bob/WEB-INF/classes/com/boblibrary/classes/util') instead of downloading it?
Therefore, the '/bob' project is using bugged classes (that I think it downloads from Internet) which I can't correct.
Thanks for your help.

Thank you for your answer, but I can't imagine where is physicaly the class that my project use and show me as http://localhost:8080/atlassian-jira-3.13.2/download/ressources/br.com.ecore.jira.plugin.projectViewPlugin:ProjectViewTabPanel/js/projectviewtabpanel.js. Where is that Javascript file suppose to be on my hard drive? Or where is that class 'br.com.ecore.jira.plugin.projectViewPlugin' suppose to be on my hard drive? If it is not dowloaded from the Internet.
I have no trace of that class on 'atlassian-jira-3.13.2/', neither on 'jdk1.6.0_18/', 'jre6/' or 'apache-tomcat-5.5.28/common/classes/'.
Thanks.

Jsp:plugin and codebase

I have a JSP with the following jsp:plugin code:
<jsp:plugin type="applet"
code="com.package.Applet.class"
codebase="/application1/applets/" width="50"
height="50">
</jsp:plugin>
Web applications, which run this applet, specify different codebase, such as /application2/applets/,
/application3/applets/ and so on.
Unfortunatelly JSP specification doesn't allow dynamic codebase in jsp:plugin and we create a new JSP for
each new web domain to specify another hardcoded codebase attribute.
Could you please advice a trick to generate codebase attribute at run-time, to deploy the same JSP in all
applications.

Well, then I would just put in the object/embed tags yourself. You can get whatever the plugin tag writes by just using the tag once with static values and view the source in the browser and copy it out, then replace whatever values with scriptlets (or other taglib tags) to fill in the correct values.

From JSP- Japplet and Back.

I know it's possible from JSP -> Japplet by the use of throwing parameters .
but how can the Japplet throw back data out for JSP to catch?

Ron
Here's what i wanted to do. I'm writing a Cinema ticket online booking system for my Group Project. I want to write an applet that can access the Oracle database indirectly thru JSP. (this is bcs I've tried JDBC and it's kind of slow and you need the user to install the JDBC package) . So the only way I came up with is thru Applet -> JSP -> ORACLE and back. Is this possible? or is there any way where i can decrease the d/l part for the JDBC package? (takes too long for 56k users).

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

How to copy procedures and packages from one server to another?

Hi,
I have 439 packages and 178 procedures located in one server called MAXWELL.
I need to copy these objects to another server called TITAN.
The schema names is SPCBR in both servers.
So both servers have an instance running with this schema SPCBR.
SPCBR in TITAN server has their tables with table data which was generated by an export/import process from MAXWELL server.
However, procedures and packages were not copied by the export/import because I used the clause 'tables'.
Now, what can I do in order to equalize procedures and packages in both databases? I can't risk in damaging or duplicating data in my database located in TITAN server, ok?
Thanks,

spool off
set heading on
set feedback on
set linesize 130
set termout on
@xtmpx.sql

You can see how to filter on that one by adding to the where clause if you want.
Just run @getallcode_INSTALL to run all of the scripts...

How can I stop the execution on a JSP page and start it again

Hi
I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
When a user does an update the transaction commits and releases its locks when the program executes
<%stmt.executeUpdate("commit!"); %>
I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
I have tried using the java.swing JOptionPane boxes but this didn?t work either
I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
Mette

I already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
But the problem is how to get the code above to stop to illustrate I have set this lock.
I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
While (i < 2)
if( i==1)
%>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
else
stmt.executeUpdate(�commit�);
I am not using threads so I cannot use the sleep function.
I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
Thanks for your help

Unicode export:Table-splitting and package splitting

Hi SAP experts,
I know there are lot of forums related to this topic, but I have some new questions and hence posting a new thread.
We are in the process of doing unicode conversion in our landscape(CRM 7.0 system based on NW 7.01) and we are running on AIX 6.1 and DB2 9.5. The database size is around 1.5 TB and hence, we want to go in for optimization for export and import in order to reduce the downtime.As a part of the process, we have tried to do table-splitting and parallel export-import to reduce the downtime.
However, we are having some doubts whether this table-splitting has actually worked in our scenario,as the export has exeucted for nearly 28 hours.
The steps followed by us :
1.) Doing the export preparation using SAPINST
2.) Doing table splitting preparation, by creating a table input file having entries in the format <tablename>%<No.of splits>.Also, we have used the latest R3ta file and the dbdb6slib.o(belonging to version 7.20 even though our system is on 7.01) using SAPINST.
3.) Starting with the export using SAPINST.
some observations and questions:
1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
2.) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th split. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
3.) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
4.) Also, what exactly is the difference between table-splitting and package-splitting? Are they both effective together?
If you have any questions and or need any clarifications and further inputs, please let me know.
It would be great, if we could get any insights on this whole procedure, as we know a lot of things are taken care by SAPINST itself in the background, but we just want to be certain that we have done the right thing and this is the way it should work.

Santosh Bhat

Hi,
First of all please ignore my very first response ... i have accidentally posted a response to some other thread...sorry for that
Now coming you your questions...
> 1.) Can package splitting and table-splitting be used together? If yes or no, what exactly is the procedure to be followed. As I observed that, the packages also have entries of the tables that we decided to split. So, does package splitting or table-splitting override the other, and only one of the two can be effective at a time?
Package splitting and table splitting works together, because both serve a different purpose
My way of doing is ...
When i do package split i choose packageLimit 1000 and also split out the tables (which i selected for table split) into seperate package (one package per table). I do it because that helps me to track those table.
Once the above is done i follow it up with the R3ta and wheresplitter for those tables.
Followed by manual migration monitor to do export/import , as mentioned in the previous reply above you need to ensure you sequenced you package properly ... large tables are exported first , use sections in the package list file , etc
> 2.) If you are well versed with table splitting procedure, could you describe maybe in brief the exact procedure?
Well i would say run R3ta (it will create multiple select queries) followed by wheresplitter (which will just split each of the select into multiple WHR files) ...
Best would go thought some document on table spliting and let me know if you have specific query. Dont miss the role of hints file.
> 3.) Also, I have mentioned about the version of R3ta and library file in my original post. Is this likely to be an issue?Also, is there a thumb rule to decide on the no.of splits for a table.
Rule is use executable of the kernel version supported by your system version. I am not well versed with 7.01 and 7.2 support ... to give you an example i should not use 700 R3ta on 640 system , although it works.
>1.) After completion of tablesplitting preparation, there were .WHR files that were generated for each of the tables in DATA directory of export location. However, how many .WHR files should be created and on what basis are they created?
If you ask for 10 split .... you will get 10 splits or in some case 11 also, the reason might be the field it is using to split the table (the where clause). But not 100% sure about it.
> 2) I will take an example of a table PRCD_CLUST(cluster table) in our environment, which we had split. We had 29 *.WHR files that were created for this particular table. The number of splits given for this table was 36 and the table size is around 72 GB.Also, we noticed that the first 28 .WHR files for this table, had lots of records but the last 29th .WHR file, had only 1 record. But we also noticed that, the packages/splits for the 1st 28 splits were created quite fast but the last one,29th one took a long time(serveral hours) to get completed.Also,lots of packages were generated(around 56) of size 1 GB each for this 29th plit. Also, there was only one R3load which was running for this 29th split, and was generating packages one by one.
Not sure why you got 29 split when you asked for 36, one reason might be the field (key) used for split didn't have more than 28 unique records. I dont know how is PRCD_CLUST split , you need to check the hints file for "key". One example can be suppose my table is split using company code, i have 10 company codes so even if i ask for 20 splits i will get only 10 splits (WHR's).
Yes the 29th file will always have less records, if you open the 29th WHR you will see that it has the "greater than clause". The 1st and the last WHR file has the "less than" and "greater than" clause , kind of a safety which allows you to prepare for the split even before you have downtime has started. This 2 WHR's ensures that no record gets missed, though you might have prepared your WHR files week before the actual migration.
> 3) Also,Our question here is that is there any thumb rule for deciding on the number of splits for a table.Also, during the export, are there any things that need to be specified, while giving the inputs when we use table splitting,in the screen?
Not aware any thumb rule. First iteration you might choose something like 10 for 50 GB , 20 for 100 GB. If any of the tables overshoots the window. They you can give a try by increase or decrease the number of splits for the table. For me couple of times the total export/import time have improved by reducing the splits of some tables (i suppose i was oversplitting those tables).

Neel

How can I compile all functions, procedures and packages with a script?

I need to compile all functions, procedures and packages of 5 schemas (users) with a script.
How can I do it?
Thanks!

you can create a script to select all invalid objects in those schemas Since Oracle 8 introduced NDS this approach has struck me as a trifle old fashioned. It's much simpler to loop round the query in PL/SQL and use EXECUTE IMMEDIATE to fire off the DDL statements. No scripts, no muss, no fuss.
Having said that, the problem with this approach and also with using DBMS_UTILITY.COMPILE_SCHEMA is that they do not compile all the invalid objects in dependency order. This may result in programs being invalidated by the subsequent compilation of dependencies. This is due to the introduction of Java into the database.
The UTLRP script is much better, because it (usually) avoids cyclic references. But you still may need to run it more than once.
In general it is better to avoid sledgehammer recompilations (like DBMS_UTILITY.COMPILE_SCHEMA, which starts by invalidating all the objects). If we have twenty invalid objects, nineteen of which are dependencies of the twentieth, we actually only need to recompile the master object, as recompiling it will trigger the recompilation of all the others.

Can a servlet read a jsp file and display its contents?

Hi,
I would like to know if Servlets can read a Jsp file and display its contents.. Right now for our website, I am using a html file to be displayed after a successful post operation through the Servlets...
-Thanks!

I posted this in another thread.
Here's some code that reads using a URL. This doesn't work with JSPs as the server executes JSP when it connects but it's useful for other file types. Note that the filename is a URI</h1>This is <code>show.jsp</code></h1>
<hr>
<%! String file = null; %>
<%! java.io.InputStream is = null; %>
<%
file = request.getParameterValues("filename")[0];
try {
is = (new java.net.URL(file)).openStream();
} catch (java.io.IOException ioe) { out.write(file + " not found!<br>"); }
java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(is));
String line = "";

Jsp include and jsp param

Hi All,
I have the following:
<jsp:include page="anotherPage.jsp">
<jsp:param name="testing" value="sdfasdfsd"/>
</jsp:include> And in anotherPage.jsp I have:
<%@ taglib uri="/WEB-INF/tld/commons-log.tld" prefix="log" %>
<log:dump scope="request"/>
<log:dump scope="session"/>
<log:dump scope="page"/>
<log:dump scope="application"/>
<h3>
Test: <%= request.getParameter("testing") %>
</h3>Not only does this output:
Test: null
but I don't see 'testing' anywhere in the dumps! What is going wrong?
Have I badly misunderstood parameter sending? :-/
Actually, my assumption was that the include code puts the "testing" variable
into the request.. 1) where does jsp:param put the data items it
passes through and 2) if the data item didn't previously exist as a
request parameter, does it ignore it?
Any assistance would be most appreciated!
Rob

Depends on the server version you are using. If you are using a JSP 2.0 server like Tomcat 5, then you should be able to do that, as long as you set up the container correctly (to use servlet 2.4 and JSP 2.0 specs rather than 2.3 and 1.2...)
Is you are using a JSP 1.2 container (less then TC5) then you will not be able to use EL anyware except in JSTL tags. The fix is to use the JSTL tags to do the include:
<c:import url="thepage.jsp">
<c:param name="param1" value="${attr}"/>
</c:import>

This is how i used to create an XML file in a JSP page only without JSP/SERVLET concept:
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
// Identify a carriage return character for each output line
int iLf = 10;
char cLf = (*char*)iLf;
// Create a new empty binary file, which will content XML output
File outputFile = *new* File("C:\\Users\\user\\workspace1\\demo\\WebContent\\YourFileName.xml");
//outputFile.createNewFile();
FileWriter outfile = *new* FileWriter(outputFile);
// the header for XML file
outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);
try {
// Define connection string and make a connection to database
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/SAMPLE","app","app");
Statement stat = conn.createStatement();
// Create a recordset
ResultSet rset = stat.executeQuery("Select * From posts");
// Expecting at least one record
*if*( !rset.next() ) {
*throw* *new* IllegalArgumentException("No data found for the posts table");
outfile.write("<Table>"+cLf);
// Parse our recordset
// Parse our recordset
*while*(rset.next()) {
outfile.write("<posts>"+cLf);
outfile.write("<postname>" + rset.getString("postname") +"</postname>"+cLf);
outfile.write("<comments>" + rset.getString("comments") +"</comments>"+cLf);
outfile.write("</posts>"+cLf);
outfile.write("</Table>"+cLf);
// Everything must be closed
rset.close();
stat.close();
conn.close();
outfile.close();
catch( Exception er ) {
%>

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.
