PHP vs ASP vs JSP for using privileges

I want to use logins on a dynamic website.
I was tell that I'd rather use jsp with ejb to do so, as ejb would communicate with the database layer and jsp with the presentation layer. In that way I have to use a very complicated business logic (4 layers).
Would you know an other way to do so, perhaps simpler but as much secure ?
God Bless, Olivier.

Its not really mandatory to use EJBs in your project. EJB's provide alot of useful stuff when you are dealing with databases, and one of those features is security. But it sounds has if you want to restrict who can access anything under a certain folder level or maybe certain file types?
If you are looking to apply this kind of security for example then you should look into Filters and apply your custom filter to /auth/*. You might want to look into using JAAS to handle user grouping and login access. Only problem I found when dealing with JAAS is if you would like to set some session attributes during their login that jaas does not do that. It handles authentication but does not give you events to signal (Hey the user logged in, now lets set this attribute)
I hope this helps.

From PHP to JSP for a search-responder.php

I have been asked to use the "search-as-you-type" solution offered up by Google at [http://code.google.com/p/search-as-you-type/|http://code.google.com/p/search-as-you-type/]. The documentation offered by Google is pretty much straight forward but of course the actual piece of code that gets the data is built in PHP and my client needs this to be used on a page serving up JSP.
I am learning JSP and moving from PHP and ASP and learning quickly but not quick enough to finish the project.
Would anyone be able and willing to help me convert the functions in the following PHP code into JSP?
Thanks in advance to anyone who takes the time to help me.

Thanks for your comment Gimbal2.
I have already been thoroughly surprised at how different JSP is from PHP. I am finding quite hard to wrap my head around the whole process to be honest.
I am beginning to see that JSP and PHP work in a totally different way than each other.
I am not technically trying to translate or convert the PHP file as much as I am trying to build a file in JSP that does the same functions. The main functions of the PHP script are commented by Google and should be easily enough re-written in JSP in order to produce similar results.
Since the output needs to be in a JSON format when passed to the .js file you'd think this would be better suited as a .jsp file as well or even a JAVA Applet, Servlet or even a bean. Since the whole site is already built in JSP for a multitude of other functions it seems likely that adding on more to read data from a source file and send it back to the .JS would be straight forward, but I could be wrong. But again I am not familiar enough with JAVA or JSP (yet) to make heads or tails of this.

How can I use 1 JSP for edit/create functionality?

Hi All,
Does anybody have an example of using one JSP for both editing and creating an object? I am pretty sure I can handle most of it, but am not sure about how I can specify different messages from the resource bundle (i.e. modifying the screen title for the different uses, "New Campaign" vs. "Edit Campaign").
My background is in PHP and DHTML (i.e. more front-end) and I'm just starting with Java and JSF. As such, I want to be sure that I'm using appropriate patterns for my programming.
Thank you in advance for any help,
Matt

I make the difference between modifying an existing object and a new one by the ID in the object. Each object has a unique ID in my app assigned by the database. So if the ID is 0, the user is creating a new object, not stored in the DB yet. I store the object to be edited/modified in the session before displaying the page:
For the title:
<h:outputText value="Edit Material" rendered="#{sessionScope.selectedMaterial.materialId != 0}"/>
<h:outputText value="New Material" rendered="#{sessionScope.selectedMaterial.materialId == 0}"/>For the action buttons:
<h:commandButton value="Update Material" action="#{MaterialControllerBean.updateMaterial}" rendered="#{sessionScope.selectedMaterial.materialId != 0}"/>
<h:commandButton value="Create Material" action="#{MaterialControllerBean.createMaterial}" rendered="#{sessionScope.selectedMaterial.materialId == 0}"/>

Use PHP or ASP to grab part of another site

Hello all,
I have permission to grab certain contents of pages of a site
that is a
static site. The static pages are updated fairly frequently,
otherwise,
I would just copy and paste.
I'd like to grab all code that is within a standard div tag
with an id
and insert it into my pages.
Is it possible to do this with script? I'm a beginner at both
PHP and
ASP, so any pointers would be great.
PS: to David Powers--great PHP for DW8 book.

It's certainly doable with PHP. Do a Google search for screen
scraping
with PHP or page scraping with PHP. You'll find quite a few
tutorials.
The theory isn't all that difficult, but a lot depends on
your PHP
setup. You may need to use cURL or a socket connection if
your host has
disabled allow_url_fopen. It would also be a lot easier if
the target
page is valid XHTML and you have PHP 5. You could then use
SimpleXML to
loop through the page nodes to find the ID you want.
Rather than try to scrape the page every time somebody
accesses your
site, I would suggest scraping on a regular basis, say once
an hour, and
storing the content in a text file or a database. Of course,
that means
you need the ability to run PHP files as scheduled events.
It would be much simpler if the other site used a text file
as an
include. You could then grab the include yourself. Much
simpler, much
less hassle.

Best Practice for using JSP in OBPM 10gr3

Hi Guys,
We are using JSP for UI in our project. We are new to the OBPM. wants to clarify some things.
1. is it good to have jsp in screenflows or if we can manage it outside BPM also with same effect
2. How is the BPM database structured. Is the PAPI API's avaialble to get all the desired information from it.
3. Is notes/attachments/audits managed in BPM database or if we can manage it in external db also.. how to access these from java if it can be managed in BPM db.
4. What are the pro's and cons of PAPI vs JMS
Thanks in Advance!!!!

1. is it good to have jsp in screenflows or if we can manage it outside BPM also with same effectOthers will probably disagree, but I always say to use Screenflows and to use the out of the box Workspace. They are built in as part of the product and you'll be facing a ton of work trying to duplicate this functionality outside.
2. How is the BPM database structured. Is the PAPI API's avaialble to get all the desired information from it.Unless it's a project variable or a variable that is marked as "Separated", the instance variables are stored in a single blob in a row in the Engine's database. PAPI can retrieve the instance variable information (I posted something on how to do this a while back on this forum and can find it if you need it).
3. Is notes/attachments/audits managed in BPM database or if we can manage it in external db also.. how to access these from java if it can be managed in BPM db.The out of the box notes and attachments are also stored as part of the blob. On the project I'm currently on, the customer wanted the attachments stored separately in an external database so we did not use the out of the box attachments. They wanted what they call "tasks" stored in a separate database. These tasks were for ad hoc queries to send a question to any department / user and then store the history of responses and routing.
4. What are the pro's and cons of PAPI vs JMSSorry - you lost me here. Sure someone else will pick up on the comparison between the API Oracle BPM uses and JMS, but I'm not getting it.

Need a good charting library (for use in a servlet/jsp environment)

Anyone know of a good charting library for use in a servlet/jsp environment.

Use JFreechart combined with cewolf.
www.object-refinery.com/jfreechart/
To use charts in a jsp page you can use cewolf ( a taglib) based on jfreechart.
http://cewolf.sourceforge.net/
Both are free.

Session-scope variable for JSP page used in a frame

Hi,
I don't know if there's a way to do this at the same time:
(1)- assign session scope to a variable (in order to be able to retrieve recurrently the previous value each time the JSP is called);
(2)- set its visibility in a way that it could be accessed only by the page that defines it. The JSP is used in a frameset along with an other JSP that can potentially define identical session-scoped variable (You understand why I want to keep them separate)
session.setAttribute():
seems not to be the thing I need
pageContext.setAttribute():
with SESSION_SCOPE, it behaves the same way as session.setAttribute(). with PAGE_SCOPE, condition (1) can't be satisfied.
Does anybody have an idea ?
Thanx in advance.

I can see that you will not want to maintain two different files for every possible page on the site!
It may be possible to do something like <frameset rows="*" cols="50%,*">
<frame name="content1" src="file.jsp?frame=one" >
<frame name="content2" src="file.jsp?frame=two" >
</frameset>and then in the jsp<%
String frame=request.getParameter("frame");
session.setAttribute(frame+"AttributeName",attributeValue);
%>This will set up two session attributes - "oneAttributeName" and "twoAttributeName". Depending on how many variables you have, this may prove just as difficult to maintain.
You may end up having to simply pass url parameters between pages to maintain state within the individual frames, which is far from elegant also.
I am interested in how you end up solving this one.

Why not use Jsp for control in MVC2 ?

hi
i am rajendra , i am preparing interview FAQ, so please give me my Que. Ans.
1) we are using servlet for control in MVC2 Module,then why we can not use
Jsp for control in mvc2
2) if we used jsp for control in mvc2 then what is disadvantage compare to if using servlet for control in mvc2
Please give me ans. as soon as..
Thanks.

Are you preparing a FAQ for others or are you just cramming before an upcoming interview and someone gave you a set of questions? It looks more like the latter to me.
If you haven't actually written any MVC based code, you won't be able to snow the interviewer. It's better to just relax, get a good night's sleep and impress them with your willingness to learn, your fit with the team and whatever real accomplishments you have to show.
If you really want an answer to this I suggest that you try writing an MVC2 system using JSP for the controller, which is possible, and then try doing the same in a servlet, or better yet using a framework like Spring MVC or Struts to provide the servlet for you and let you concentrate on your application.

OC4J 9.0.4 migrate to 10.1.3.1 JSP fails using abstract class for ResultSet

Consider the following JSP code snipet:
<%
com.class.SQLDataSource detail = ((com.class.SQLDataSource)request.getAttribute("AcctList"));
%>
<%while detail.next()) {detail.getRow();%>
<tr ...>
<td ...><%= detail.getString("ACCT") %></td>
</tr>
<%}%>
blah, blah, blah
class snipet looks like this:
public abstarct class SQLDataSource extends serializable {
private ResultSet resultSet = null;
private PreparesStatement stmt = null;
public boolean next() throws SQLException {
boolean result = getResultSet().next();
return (result);
public String getString(String columnName) throws SQLExcpetion {
return getResultSet().getString(columnName);
public void execute() throws SQLException {
-- checks stmt
-- if null generates resultSet from "AcctList.sql" query
-- if not null, re-executes as-is stmt for a query only
protected ResultSet getResultSet() throws SQLException {
execute(); // see above
return resultSet;
The problem:
<%= detail.getString("ACCT") %> generates a NullPointerException
Yet, if I add debug statements in the SQLDataSouce class, they conclusively show that resultSet has 1902 rows and I can diplay the contents on these rows (on the console, of course, the JSP still generates a NullPointerException).
If I "hardcode" the creation of a ResultSet in the JSP, the pages displays properly (not the desired method).
PLEASE TAKE NOTE: This JSP/Class combination works PERFECTLY in OC4J 9.0.4 using JDeveloper 9.0.5.2. When I deploy the **EXACT SAME** JSP/Class combination in JDeveloper/OC4J 10.1.3.1, I receive the NullPointerException.
So what this feels like to me (and my VERY limited J2EE experinece) is that the abstract class SQLDataSource has somehow lost/closed/dropped/corrupted resultSet when "returning" to the JSP for display of the contents of resultSet. This is, of course, a laymans explanation of the experienced effect of running this code.
It makes me wonder if under 10.1.3.1 "something more" must be done so that the (abstract) SQLDataSource class can operate in the same way it did under 9.0.4.
Last note: this NullPointerException happens whether I deploy to standalone OC4J 10.1.3.1 or if I execute my application withing JDevloper's Embedded OC4J instance.
Any Assistance on this MOST aggrivating problem would be greatly appreciated.
Others have yet to solve it in similar posts of mine. Hopefully this more definitive description will help YOU be my personal HERO.

Plugin for eclipse for using log4j in jsp ?

Hello all,
Plz tell me is there any plugin (eclipse) for using log4j in jsp pages similar to log4e. As log4e is not working with jsp in Myeclipse
Thanx

Hello Prasad,
I used log4e plugin to use log4j in eclipse. Its also working fine with servlets in eclipse. For working with web applications i installed MyEclipse. In this when i right click on the servlet editor log4e item is shown for automatic adding of log4j instructions(like adding logger etc) but when i try to use it by opening the jsp page log4e option is not in menu when right clicked. So i think for jsp seperate plugin is needed.
What do u think.

Master-detail jsp for bc4j using JBO tags

PHP to ASP?

Hi!
We are looking into upgrading our intranet files at my company. Right now, although they are effectively "plain vanilla" html, for some reason we have been using the asp format.
Our next evolution may involve using FMStudio to allow the intranet users to interact with our Filemaker database. These pages would be output in the php format.
I am wondering if I can convert these to asp without losing significant functionality. Thanks!

Xynoplas wrote:
...whether a page with an .asp extension can be used to call PHP functions, and how this would be done.
In case you´re running an Apache server, this is possible by adding one of the following lines to a .htaccess file which should be placed in the "public_html" user directory to affect all .asp files
a) AddType application/x-httpd-php .asp
b) AddHandler application/x-httpd-php .asp
Version a) applies when PHP is installed as module in Apache, the second version is suitable when PHP is installed as CGI binary.
The result is, that your .asp pages will be parsed by PHP and hence can contain PHP stuff.
