Jsp syntax for avoiding caching of pages at client

how can we avoid a jsp page from caching
which is so in ASP
response.expires
what is that in jsp

If you are using Apache as your WebServer look at
http://httpd.apache.org/docs/mod/mod_expires.html
You can solve the caching problem by adding
ExpiresActive On
ExpiresDefault "access plus 1 second"
to the Apache httpd.conf file
null

API for clearing cache of page items

Is there an API for clearing the cache of page items? I see there is a procedure called CLEAR_PAGE_CACHE in APEX_UTIL package to clear the cache of all the items on a page, but wanted the equivalent for an item. Maybe I'm making this harder than needed. No idea.
I realize there is the option of creating a page process called "Clear Cache for Items (ITEM,ITEM,ITEM)" on a page, but I am trying to do this in an application-level process.
Shane.

FYI... I found that using [ apex_util.set_session_state ( 'item name', '' ); ] worked for me.

JSP Syntax for binding JSF components

I am trying to bind to a map with session scope and the key into the map is
a string value. It seems that this binding does not work as the key is not found
before rendering.
<f:selectItems id="listbox1SelectItems" value="#{idGeneratorBean.myIds['key']}"/>
The key is a hidden field on the page, and if hard-coded in the above, it will find that data.
I've seen other postings where the binding is done in the component's initialization code.
If it is done that way, what should the jsp binding look like?

Please don't crosspost topics over all places. Stick to one topic.

WLS 9.2.2: JSP recompile for every page load with JAR'ed tag files

I have a small custom tag library of three tag files. With the server running in development mode and the tag files in a JAR (included in WEB-INF/lib), the server appears to be doing a JSP recompile on every page load. However, it only compiles on the first page load if the tag files are included in WEB-INF/tags (no JAR). Also, running the server in production mode with the JAR'ed tag files avoids the recompile for every page load.
          Is that how the server should behave?
          For whatever it's worth, I'm also using Eclipse 3.3.2 with WTP and WebLogic Server Tools 1.1.2. The server is running the Sun JVM (1.5_10).

Vikram,

Hi,
I'm trying to call html page (stored on server) in my pl/sql package!
I have already create html page in pl/sql package code and it's works fine.
Now create better html page (interface design) and stored on server. I would like to call that stored html page in my pl/sql package.
What is syntax for calling html page in PL/SQL or could you suggest me some literature.
In first option I had created ces and stored it on server. Then I call it in pl/sql package like htp.p('<link rel="stylesheet" href="\download\table_style.css" type="text/css">');
I try someting like that for calling html page but it doesn't works.
htp.p('<link rel="form" href="\download\interface.htm" type="text/html">');
Does anyone know syntax for calling html page in pl/sql?!?
Thanks!

it works

Syntax for page level process to invoke an on-demand app level process?

I want to use a page level process (if that's the right thing to do) to run an application process on-demand each time certain pages load. What is the proper syntax for the page level process?
I tried many variations of the following but it does not pass syntax checking.
1.
APPLICATION_PROCESS=GLOBAL_UPDATE;
2.
begin
APPLICATION_PROCESS=GLOBAL_UPDATE;
end;
What is the proper syntax?
Thanks,
Linda

Linda - If you want to run an application process when certain pages load, just create an application process (PL/SQL type) with the desired firing point, e.g., On Load: Before Header and in the process condition use a condition type like "Current Page Is Contained Within Expression 1 (comma delimited list of pages)". No need to create either a page process or an on-demand application process to do this.

Why does people use JSP Tag for their JSP page? (Urgent)

I don't know what benifit if I am using JSP Tag.
If anyone knows, pls give me an idea and the advantage of using JSP Tag in JSP Page!
Thanks in advance!

You have to read a little about JSP, JSP stands for JavaServer Pages, you can use jsp tags and you can use java code. If you dont want to use jsp tags then you should just write html file, if you just want to use java, then write java class or a servlet.
The need for jsp arised because people were inserting html code inside a servlet class..a big no no..and a headache. JSP separate model from the view...read a little about MVC-2 model view controller pattern.
Also read some tutorial on this website...good luck

The syntax for accessing MS SQL db from JSP

Can anybody help me with the syntax for accessing MS SQL db from JSP???
This is what I do when I use MySQL:
Class.forName( "org.gjt.mm.mysql.Driver" );
Connection conn = DriverManager.getConnection(
"jdbc:mysql:://um" ,
What do I write when it is MS SQL and where do I install the driver

One way of doing this is to use ODBC. Here's an example:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:<odbc name>", "<login>", "<password>");

Avoid caching in the client

I'm using servlets + jsp technology.
I have a form that inserts a person in the database.
When you post the form the servlet attends the request in the doPost method, calls a DAO object that inserts this data in the database, asigning an id number for this person and giving it back. to the servlet.
Then the servlet sends back a page that informs that the person has been inserted.
At this point (with the result page in the browser), the user click the back button. This shows the form again with all the data the he has completed before. If he click the OK button the form is posted again to the servlet, and a new person is inserted in the database with a new id. But this person is the same.
How can I avoid this?
I don't know if I'm clear enough. Please help
Thanks

For even more aggressive "don't cache this page", especially to fight various Microsoft IE versions' caching "features":
    public static void disableCaching(HttpServletResponse response)
        response.addDateHeader("Expires", 791589600000L); // Wed Feb 01 00:00:00 EET 1995
        response.addHeader("Cache-Control", "no-store,no-cache,must-revalidate,post-check=0,pre-check=0");
        response.addHeader("Pragma", "no-cache");
    }For more info: http://www.google.com/search?q=no-cache+pre-check+post-check+pragma

How to find JSP syntax Errors

Dear All.
I develop JSP in EP environment by NW Studio, I fond it is difficult to find JSP syntax Errors when I wrote the JSP, I ever view EP log, but the information is so general, it only told me "Error occurs during the compilation of java generated from the jsp" and so so, I can't find more detail information , could you tell me how can I find the syntax Errors quickly?

Hi,
The error should be somewhere in the log or trace file.
Try default.trc in Visual Administrator (Log viewer) to look for more detail.
Another possibility is to look for plugins that are compatible with NWDS and that can (pre)compile JSP's. Anyone....?
In general is it is wise to keep your JSP's small, so use jsp:include (or page include) where possible. Also to avoid duplication of code. Indentation also helps to keep code readable.
Good luck,
Roelof

Mixing XML syntax w/JSP syntax

As I understand it, you can use either the JSP-specific syntax or an XML-based syntax for code in a JSP page. For instance you can use either
<%= expresssion %>(JSP-specific syntax)
or
<jsp:expression>
expression
</jsp:expression>(XML-based syntax)
to do much the same thing. But I think once I heard somewhere that the two syntaxes cannot be mixed on the same JSP page. Two questions about that:
(1) Is it true?
(2) If it is true, what about a page of one syntax that includes (using include directive) a page of the other syntax -- there will be inconsistency here.
Thanks if you can answer this.

A jsp source file(.jsp) should be in either Xml syntax or Jsp syntax.

How can we add a control on our .jsp webpage for uploading several image fi

How can we add a control on our .jsp webpage for uploading several image files as done in gmail attachment, Where a Remove button also appears if we wanna remove the particular attachment.

The SCOM Management Server is in Domain A. I've tried it already and it has failed.
So just to clarify the method I used was to go to Administration>Security>User Roles. Then New User Role>Read-Only Operator. In the Create User Role Wizard I then gave the User Role a name, Clicked "Add" under User Role Members.
Then the Select Users or Groups window pops up and I changed the Locations from Domain A to Domain B and searched for the user, which it's able to find, then clicked "OK" to add it to the User Role members which it does just fine. On
the next page which is Group Scope I checked the one group I want this account to have access to and then click next. This brings me to Dashboards and Views where I click the radio button for "Only the dashboards and views selected in each tab are
approved" and chose the folder of dashboards I want this account to access and then click next. This brings me to the Summary and I click "Create". At this point it thinks for a moment then closes out the wizard but the new Read-Only
Operator does not appear. I then look in Event Viewer and see the Event I pasted above.
Am I doing something wrong here? Any guidance on how to get around this issue would be much appreciated.
Thanks,
Jake
