PL/SQL vs JSP vs Servlets

We are in the stage of deciding which language to develop portlets. I lean towards JSP or servlets for the wide array of Java libraries we can use. I think the only advantage of PL/SQL is speed. Thanks.

It depends. If your developers are mainly Java developers, you'll probably prefer building web portlets. But if you have a strong PL/SQL skill set you could choose the latter. Additionally, if you're developing content that is database intensive you may want to build PL/SQL portlets since they transact with the database faster. If you're going to aggregate content from various web sites, using web providers is preferable. It's a matter of choice based on your requirements and preferences.

SQL in JSP - do I use JAVA code in % ... % or SQL Tag Library ??

I have a small web app that makes needs to make about 12 SQL queries in a JSP and am trying to figure out what is the best way to do this
I had initially coded this using plain JAVA code in the JSP as follows :-
<%
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try {
st = conn.createStatement();
rs = st.executeQuery("select .........");
%>
But then I came across the SQL Tag Library in an article and wonder if this is more efficient code?
If so does anyone have a pointer to a good intro to these tags as they look complicated (I only am doing queries on the SQL database, no inserts or updates)

Sometimes you've gotta do what you've gotta do.
My rule is "no scriptlets".
If you MUST access a database from a JSP, the only right way to do it is to use JSTL <sql> tags.

Integration of PL/SQL and JSP (Java Server Pages)

I need to match a web application developed with PL/SQL with another developed in JSP (Java Server Pages) the problem is that the two apps interact with the same databese, an share de same users, I need to know how to get the user and password loged into pl/sql when the user want to use same of de .jsp pages running on another application server?

Hi Michael Vstling,
Did you try the java classes library (SDOAPI) that can be downloaded from OTN?
It may provide you with a better alternative when manipulating geometries in the Java space. There is an adapter in SDOAPI which can convert a JDBC STRUCT object into Java Geometry object defined in SDOAPI, and vice versa.
There are at least two ways in mixing PL/SQL and Java. The first one, as you mentioned, is to define your custom function in terms of PL/SQL and call it from within your Java program. With SDOAPI, you have the second option, which is to define your own functions in Java using SDOAPI and deploy them as Java stored procedures in db. You can then call them from within your PL/SQL code. In either way performance depends on a lot of things and generally it requires a "try and improve" approach.
About JPublisher and sdo_ordinate_array it may not be a spatial related problem. Did you try search the Java-related forums first?

SQL from JSP

Hi everybody,
i started to program in JSP only from yesterday and i'd like to execute a statement SQL from my JSP page....
My code is
<%Class.forName("oracle.jdbc.driver.OracleDriver");%>
<%java.sql.Connection c = java.sql.DriverManager.getConnection("ora817", "protocs", "protocs");%>
<% try {
Statement dbst = c.createStatement();
ResultSet rs;
rs = dbst.executeQuery("update upload_status set stato= 4;");
c.close ();
catch (SQLException e) {
out.println("Non riesco a fare l'update "+e);
return;
%>
So when i use use JDeveloper and i run the project i obtain the following error

I hope that some one can help me

Let's see.
You don't have the Oracle JDBC driver JAR in the CLASSPATH. Put it in WEB-INF/lib in your Web app's WAR file.
Your Oracle database URL is totally wrong. It should look something like this:
jdbc:oracle:thin:@host:1521:database
You should separate out that JDBC code and test it in a separate object on the command line before you try sticking it into a JSP. At least make sure that you know how to connect to the database.
Sounds like you need these:

Anybody using Hypersonic SQL in JSP?

Hello,
Does anybody use Hypersonic SQL?
I implement a guestbook system with JSP that
saves data in Hypersonic SQL. This system
runs on www.mycgiserver.com. My JSP program
has thread safe option set to false to make
sure one thread is reading and writing the database
at a time. However, every once in a while, the
database will be wiped out mysteriously.
So I am just wondering that this happens to
anyone else? Is this a Hypersonic SQL's bug
or it's the server that goofs up or I did something
wrong with the JSP setting? Any ideas or
comments please? Thanks !!!

Hi there!
I use Hypersonic locally and on mycgiserver.com. Luckilly, I haven't encountered your problems so far. I use a similar approach, I have a bean that handles a singleton-connection to the DB, and that will queue up all requests. But so far , I haven't had that much load on the app, so maybe I'll get back in this matter, with the same problem... Anyone att mycgiserver that had an id�a?
regards
Markus

Need an information using java.sql in jsp

I found that there is a 'dataset' like architecture in .NET, is there any 'dataset' like substance in our java, if it is means can you give me some ideas for using it in jsp, give me some example for saving a record in the mysql database. very urgent please,

Shouldn't be doing database stuff in JSPs. Use JSTL and its <sql> tags if you must.
RowSet might be close. I don't write .NET.

SQL and JSP compatablility

This part of code is not working properly as the JSP code has not been encorporated properly in the sql statement after LIKE.
java.sql.ResultSet RS = statement.executeQuery("SELECT BookID, Ebook.AuthorID, Surname, BookTitle, FileSize, Description, Price, Image FROM Author INNER JOIN Ebook ON Author.AuthorID = Ebook.AuthorID WHERE BookTitle LIKE '*" + bookTitle2 + "*' AND Surname LIKE '*" + surname2 + "*'");
It doesn't display the shopping cart but if I change the sql code to:
WHERE BookTitle LIKE '* queen *' AND Surname LIKE '**'
It works so I know its not the SQL code. I have included the code for the entire page below in case you spot any glaring mistakes.

David,
I want to change the where clause dynamically.Our objective is to make the map in a generic way so that if there is a change in where clause (i.e. adding more conditions in where clause) i dont have to change the map.I can change the values(if used, say emp_no=20) however i'm facing problem changing the whole condition i.e. even the column name.

Sql in jsp - decrease fines by amount

hi everyone, thx for looking at my problem, well can u pls help me to sort out this problem. the situation is when someone pays his/her fines by certain amount , i need to update the fines in the database.
here is a a section of the program:
String mem_ID= request.getParameter("mem_ID");
String fines = request.getParameter("fines");
String amount = request.getParameter("amount");
int rowsAffected = SQLStatement.executeUpdate("update member set fines = (fines-'"+amount+"') where mem_ID ="+mem_ID);
thanking u in advance

hi dear,
final solution.........
String mem_ID= request.getParameter("mem_ID");
String fines = request.getParameter("fines");
String amount = request.getParameter("amount");
float newFines = Float.parseFloat(fines) - Float.parseFloat(amount);
int rowsAffected = SQLStatement.executeUpdate("update member set fines = '" + newFines + "' where mem_ID =" + mem_ID);
// unless required very high precision, avoid usage of double - u may face unpredictable results
bye for now...

For this, you need to check the docs related to MSSQL. That quite depends upopn the database one is using.

Can someone help me correct this sql statement in a jsp page?

ive been getting the java.sql.SQLException: Incorrect syntax error for one of my sql nested statements. i cant seem to find similar egs online, so reckon if anyone here could help, really appreciate it.
as im putting the nested sql in jsp page, it has to be with lots of " " n crap. very confusing if there are nested.
heres the sql statement without those "" that i want to use:
select top 5 * from(
select top+"'"+offset+"'"+" * from prod where cat=" +"'" cat "'"+"
)order by prodID desc
when i put this in my jsp pg, i had to add "" to become:
String sql = "select top 5 * from("+"select top"+"'"+offset+"'"+" * from prod where cat=" +"'" +cat+ "'"+")order by prodID desc";cat=" +"'" cat "'"+")order by prodID desc";
all those "" are confusing me to no end, so i cant figure out what should be the correct syntax. the error says the syntax error is near the offset.

If offset is, say, 10, and cat is, say, "new", then it looks like you're going to produce the SQL:
select top 5 * from(
select top '10' * from prod where cat='new'
)order by prodID descThat looks exactly like incorrect syntax to me... top almost certainly can't handle a string literal as its operand... you almost certainly would want "top 10" instead of "top '10'"...
If you use PreparedStatement, you don't have to remember what you quote and what you don't and you can have your SQL in a single static final string to boot...

Pass jstl sql query result to jsp

Hi I have the following code which works perfectly
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" sql="SELECT * FROM homepagesubscriptions">
</sql:query>
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
</table>   Now what I want is to perform the query in one page and then display the data in another, as such
index.jsp
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" sql="SELECT * FROM homepagesubscriptions">
</sql:query>

    test.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="items" value="${resultBean}" />
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
</table>   I know in index.jsp I can use jsp forward and usebean but am not sure how to? What type is the result from the query? thanks

Take a look at the "scope" attribute of the <sql:query> tag.
query.jsp:
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" scope="request" sql="SELECT * FROM homepagesubscriptions"/>
<jsp:forward page="test.jsp" />and then test.jsp:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
</table>
