Jsp newbie, please help about @include

I am new to JSP.
I have two jsp files, say , jsp1 and jsp2.
JSP2 is perfectly working. I want to display the result of jsp2 with the result of jsp1.
But I additionally want to supply a value from jsp1 to a variable in jsp2 before calling jsp2.
The result of jsp2 depends on the value supplied.
I couldn't figure out how to do this. A simple @include directive like
<%@ include file="jsp2.jsp" %> doesn't seem to be suitable here.
What options are available here? Please help.
Thank you.

Thank you friends for the suggestion. I have yet to try your suggestions.
Before that I came across another problem. Would someone help please?
Why the jsp fails when I include the same JSP page twice in another jsp page?
Of the following two jsp files, the upper one is OK, but the lower one complains that it cannot compile (org.apache.jasper.JasperException).
test1.jsp:
<html><head><title></title></head>
<body>
<table>
<tr><td><%@ include file="single.jsp" %></td></tr>
</table>
</body>
</html>
test2.jsp:
<html><head><title></title></head>
<body>
<table>
<tr>
<td><%@ include file="single.jsp" %></td>
<td><%@ include file="single.jsp" %></td>
</tr>
</table>
</body>
</html>
I want to populate the cells of an HTML table with the results from the same jsp file, by supplying different values to a variable in the jsp file so that its results will be different for each cell. Am I being to foolish here?
Thanks.

Issue about jsp taglib,please help

Hello all,
I want to use jsp tag like following:
<c:import url="xxx.jsp">
<c:param name="xxxAction" value="<portlet:renderURL/>"/>
</c:import>
and the value of the c:param can not accept the value generated by the <portlet:renderURL/> tag.
I can resolve the issue by writing java code in the jsp(like ...java code...<c:param name="xxxAction" value="%=...%"/> ),much java code occur in the jsp,I do not like this solution.
anybody has good solution please help me.
thanks and rgds.

Ram is correct. You can't nest custom tags as attributes to other custom tags.
In this case the <c:param> tag offers the option of specifying the value as the body of the tag though, so the following should work:
<c:import url="xxx.jsp">
<c:param name="xxxAction"><portlet:renderURL/></c:param>
</c:import>

Please help about encode password idm !!!!

Hello All,
I'm a newbie in IDM and in my work I have to encode password with CBC Algorithm before insert password in database (SQL server 2005).
So I have already coding CBC Algorithm but I don't know where I put my CBC encoding Algorithm for when users change password on IDM.
Please help me.
Thank you for advance.

I'm assuming you're not talking about storing the password that way in the IDM repository but rather a separate database resource.
I had a similar requirement with a different encryption algorithm and an Oracle database. I made my life a lot easier by having the database resource do the encryption. IDM will insert the password into the resource as plain text and, in my case, a trigger will catch it, call a stored procedure to change it from plain text to encrypted and then insert it. Since IDM never reads passwords from resources anyway the password was fully encrypted as stored in the resource and IDM never knows any better.
Technically speaking you could have created a rule or custom form to do the password encryption before IDM sends it over the wire but if you've got an encrypted channel to the database then you might take my approach and skip having IDM do it altogether.

Junk characters like" � � "displayed in the jsp page please help.

Hi,
I am getting junk characters like � � displayed in the jsp page.
In the JSP page i used javascript "& nbsp" for appending spaces to a string "CCR" to get "CCR " .
Now the Resultant string "CCR " has three spaces appended to its right.
This String is set in session in that JSP page.
In the next JSP page i am getting that string from session.
After getting the string the "substring" function is performed to get only the first 5 charcters of the string. Now the result is displayed as " CCR� � " with has last 2 characters as junk values � � insteed of displaying as "CCR ". Please help me in solving this issue.
Please note that initially the sting "CCR" is got from the Oracle database in Solaris Machine.
Regards,
Vijay

have you tried:
strenuously inspecting the string that is coming from the db? do an actual loop over the string, character by character, dumping to System.out to make sure the characters are EXACT coming out of the db.
note you have to append " " not just "& nbsp"
post the code that is doing the output. the relevant bean code, the jsp, everything relevant - WITH COMMENTS discussing where things are happening.
Also, is it "weird characters" in the browser only? have you done a view source on the actual html source that the browser is rendering (right click in IE and click view source). browsers can act odd if you don't feed then exactly what they want, and it looks like you're feeding it escaped characters that it is rendering as something else.

Please help about Report Printer and PS tables-objects . ..

Hi everybody
I'm in trouble. I have a requirement in PS módule related with reports created by the Report Printer tool. I don't have any idea about these topics.
My requirement is to create a report (not with Report Printer) with the structure for projects, with all the structure Project-WBS-Network-Activity and with some values like Budget, Commit, Actual, Paid, etc.
The functional consultant only tells me about some reports created with Report Printer wich have the columns required, some report has the Budget, other one has the Commit, etc. For example, one report is the tcode S_ALR_87013532; i don't know if this transaction exists in all the SAP implementations or if it was created only for my company.
These reports only show two levels (Project-Network) so i i have to investigate:
1. How to get all the structure levels (project-WBS-network-activity)
2. How to 'translate' in code some value showed in a report created with Report Printer, i guess these values are created with formules and objects.
3. How to get the same values showed in these reports, but for the Networks and Activities.
I do not know anything about PS module and Report Printer and i really don't have any idea about how to make my development.
4. I think the functional consultant could be able to create the report himself with the Report Printer, but he tells me he does not manage this tool so good and he wants to send SAP mails with the reports, and he say the reports created with Report Printer can not send mails. Is this true ? and then, would be easier for me to learn Report Printer and create the report myself instead to develop it ?
Does somebody can help me ? Any idea ?
Please help !! I don't know even how to start with this.
Thanks in advance ..

JSP frameset (Please help)

What in the world happen? I have to surrender myself to the simple HTML. Ok, I have a a.jsp that contains the following code:
<html>
<head>
<title>JSP Page</title>
</head>
<body>
<h1>JSP Page</h1>
<FRAMESET ROWS="80,20" NORESIZE>
<FRAME SRC="main.jsp" NAME=upframe SCROLLING=NO>
<FRAME SRC="transfer.jsp" NAME=downframe SCROLLING=NO>
</FRAMESET>
</body>
</html>
As you can see, it's fairly straightforward and simple. But, the problem is I can't view the content of main.jsp and transfer.jsp which contains some text inside them! Please help.It's not even starting my work, i am stucked with this HTML problem. Unbelievable.

<FRAMESET ROWS="80,20" NORESIZE>
<FRAMESET ROWS="80%,20%" NORESIZE>Try this.
And also you should not use <BODY> tag when you use <FRAMESET>. So remove this and also remove <h1> tag and line from the page.

The sun's site provides a detailed introduction to JDBC. or
have to google for JDBC and once you've understood the JDBC concept, then you could progress from there. There is no simple way of doing what you asked.
You will need a database, though you could use MS Access. But you still need the JDBC.

Someone please help about my bubble pointer

so when im randomly searching through text online(mostly using firefox), fast or slow, the pointer goes from looking normal, to zooming into a big ugly bold/bubbly fat looking pointer. its bizarre cause at first i really didnt noticed, but as i used mozilla more often, the problem occurred more frequently. honestly, its getting distracting to the point that i've stopped using firefox, and am using safari, which isnt bad, except for im used to firefox, and i like it.
I've come to another similar discussion posted her on apple discussions, and no helpful solutions, just alot of complaints. PLEASE HELP!!! does anyone evem know what im talking about?

What do i check? I downloaded Firefox, everything went fine and the settings are normal.

Problems with Servlet to JSP communication please help!!!

Hello All ,
we have different web applications running
e.g.
We have 2 webApp named A and B are running and there URL are
http://localhost:8080/A and
http://localhost:8080/B
and we have one common WebApp running at
http://localhost:8080/common
Our problem is that whenever a user log in to the system he/she will first call the
common URL and then enter his user name and password
and depending on his username we have redirect user to either A or B with his pasword and username as parameter to the request.
i.e. in common module whenever i get userName and password we call a Servlet to authenticate the user and to detemine which webapp to forward to..
i have to call jsp accordingly from servlet in common webApp to JSP in different webapp.
I m wonderning how it is possilble.
As
i don't know how to call another webApp using
RequestDispatcher.forward () method and
also
i am not able to set paramters with the request whenever i user response.sendRedirect() method
I am wondering what could be the way to pass paramer to the request from servlet in one webApp to JSP in another webApp
Please help its urgent!!!
thankx in advance

forward() can't call another webapp.
There are several ways you could do this.
1) Share the session object across both webapps and set something as an attribute of the session.
2) Use a database or file storage to record the transaction, then go to the second webapp, which picks up that info.

Please help about HttpConnection

Hi all,
I am facing a typical problem about HttpConnection() for BlackBerry.But it is working fine in all other devices except BlackBerry.Bellow is the code:
public synchronized String getResponse(String sRequest)
String sReturn = null;
HttpConnection c = null;
java.io.InputStream is = null;
StringBuffer sb = new StringBuffer();
int ch;
int rc;
try {
sRequest=sRequest.trim();
c = (HttpConnection) Connector.open(sRequest);
c.setRequestProperty("User-Agent", System.getProperty("microedition.profiles"));
c.setRequestProperty("Content-Type", "application/octet-stream");
rc = c.getResponseCode();
if (rc != HttpConnection.HTTP_OK) {
return null;
is = c.openInputStream();
while ((ch = is.read()) != -1) {
sb.append((char)ch);
is.close();
c.close();
sReturn = sb.toString();
} catch(Exception e) {
System.out.println("URLCatch : "+sRequest);
sReturn = null;
return sReturn ;
}*"sRequest" is a simple URL String without any WAPGatewayIP & WAPGatewayAPN.*
Please tell me what is the wrong inside this connection method? Why this is not establishing the connection in BlackBerry? Should i have to change anything in this method for BlackBerry?I tried a lot but colud not solve.
Please help.
Thanks in advance

Newbie needs help about Data Encryption

bought a Wireless G router Saturday, followed the instruction on the cd and hooked up the router to the Desktop (ME) and the cable modem. I am happy that my new laptop (XP) can surf the Internet anywhere in the house.
Can anyone see what I can doing when I surf the net via the laptop (wireless)? Can they see for example what I am typing in a Word document?
Since the desktop is connected to the router, can anyone see what's in my desktop computer?
On the laptop, I click on properties of Linksys router, it says: Data Encryptiopn No.
Do I need to set the laptop up for data encrytion? What is it encryting? stuff I type in my e-mail? stuff I type using Word? Does it only encrypt stuff that I send through the Internet?
What's WAP, WEP? Do I need it?
I called Linksys Tech Support, gave up after waiting for 30 minutes.
Please help.

No, no one can see what you type on your WORD document or whatever you are doing on your computers. It says NO ENCRYPTION because you have'nt enabled any security on your router. What the encryption does, is that it prevents other people that has a wireless PC to connect in your wireless network and get internet access. Once the encryption is enabled, if a PC tries to connect, it will be asked for a password, so if they input the incorrect password, they will not be able to connect and use your internet access. Did I make it clear?
WPA and WEP are types of encryption. WPA is more secured but it is not compatible with all wireless cards or laptop PC (if they are wireless ready). So i do suggest you use WEP on your router.
