Using ActiveX from JSP or alternative to using Excel

Hi, I'm newbie in Java, and I have one problem I want
to generate Excel Charts from Java, and I don't know
if I can call an ActiveX control or COM component from
Java, and if it isn't possible I want to know some
modules that I can use to generate charts for using it
in an HTML web page, thanks a lot. There are 2 possibilities:
1) Use Java <-> Com bridges - there are 2 of them Sun's COM->EJB and IBM's EJB->COM (probably visa-versa). Look at:
http://www.theserverside.com/home/thread.jsp?thread_id=7588
and
http://www-3.ibm.com/software/webservers/appserv/doc/v40/aee/wasee_content/xjb/concepts/cxjbovw.htm
There are also (I heard) other implementations of ActiveX<->EJB bridges
2) You could use POI - it's open source http://jakarta.apache.org/poi/
POI means Poor Obfuscation Implementation - it's really poor... and I'm not sure that it supports charts - though with common sheets it works well.

That's the code that you need to execute but you should
probably encapsulate that code in Custom Action.
Orion has a EJB Tag Library that is free to distribute that
does all that stuff you just set some attributes.
Go to their site and look at their Tag Libraries.

How to connect oracle database using DSN from jsp

hello, can any know how can i connect to[b] oracle database using DSN name from jsp .I am using oracle 9i and Tomcat 5
Using odbc tool i have created the dsn name but ithe connection does not make .here is the code that i have tried
Connection connection = null;
     try
          Class.forName("oracle.jdbc.driver.OracleDriver");
     catch(ClassNotFoundException Exception)
          out.println("error occoured during loading the driver ");
     try
          out.println("getting the connection");
          connection = DriverManager.getConnection("jdbc:oracle:deepak","scott","tiger");
          out.println("connection getted");
     catch(Exception exception1)
          out.println("error occoured ");
pls help as soon as possible
Sorry, for my english

you are actually using JDBC so the DSN entry does not matter.
2 things.
Make sure that your oracle database driver is in your classpath on your tomcat server.
I.E. copy the file classes12.jar into your common/lib folder of tomcat, or into your WEB-INF/lib folder of your application. and RESTART your server. classes12.jar can be found on the internet or more easily somewhere within your oracle installation. just search for it.
Make sure your jdbc url is correct. I believe it goes like this.... fill in the blacks
connection conn = DriverManager.getConnection("jdbc:oracle:thin:scott/tiger@MyOracleHost:1521:MyDB");Note how the username are passed in the first string there fore there is no need to pass additional parameters. This method may be depriciated, but if so, just take out the user and pass from the string and continue to pass them as 3 seperate strings.
connection conn = DriverManager.getConnection("jdbc:oracle:thin:MyOracleHost:1521:MyDB","scott","tiger");That should get your connection. if not, post your errors.

Using JSObject from jsp..

Hello there,
I am trying to use the netscape.javascript.JSObject from a jsp page. However, it looks like, JSObject is only to be used from an applet. Is it true? If it's not possible to use JSObject from the jsp page, is there a way that I can evaluate a Javascript expression in my Java code and assign its value to a Java variable?
Thanks a lot in advance!

The Java code in the jsp file is executed on the server side, whereas the javascript stuff is executed on the client. So it's wonky to figure out what the heck you're trying to do.

Using SQLJ from JSP in JDeveloper

Hello,
Has anyone succeeded in creating a JSP file by using SQLJ in JDeveloper 3.1 (Build 681)?
In the whitepaper http://technet.oracle.com/docs/tech/java/servlets/jsp/whitepapers/jsp-oow99-paper.pdf
it is stated that you can create an SQLJ-JSP by giving the JSP file the .sqljsp extension. This results in an "Fatal error: compiler internal error." in JDeveloper.
In the same whitepaper, it is stated that you can also use the following JSP page directive to create an SQLJ-JSP page:
"<%@ page language="sqlj" %>"
This results in an "Error: (16) illegal character." error in JDeveloper at the mere sight of "#sql".
Any help would be appreciated.

Using ActiveX controls in GUI application, which uses TestStand API

When using ActiveX controls in TestStand Operator Interface GUI,
CVI reports User Interface Library error no.-143:
"ActiveX control Error" on attempt to load panel, which contains ActiveX controls.
The same code, which takes care of user interface, but not references
TestStand ActiveX API (i.e. not creates TS Engine), works properly.
What's wrong?

Hello again Misha,
Sorry about my previous answer, I overlooked the fact that you were saying this error was caused by placing ActiveX controls in your Operator Interface (OI) GUI (as my example shows I thought the problem was with GUIs displayed from step code modules).
Nevertheless, the problem is still being caused by the same issue, and is solved in a similar fashion. The source for the CVI OI initializes the TestStand engine before it loads/displays the UI panels. The calls to initialize the engine seem to be CoInitializing the main GUI thread as multithreaded apartment (MTA) mode whereas you will need it to be single threaded apartment (STA) mode in order for the ActiveX control container to work properly. The TestStand engine is compatible with either modes, but only one can be in place at a given time. If we CoInitialize the OI's main GUI thread as STA this will solve the problem (the subsequent attempts of setting it to MTA will fail, but again this is ok since the engine is compatible with STA).
In order to perform this functionality you will need to put a call to CoInitializeEx in the main function of the CVI OI source (this will also require that you #include the "windows.h" file at the top of the source also). Here is what the main function in your main.c file for the CVI OI will look like once you have done this:
int main(int argc, char **argv)
int retval = -1;
sArgc = argc;
sArgv = argv;
if(InitCVIRTE(0, argv, 0) == 0) /* Initialize CVI libraries */
goto Done; /* out of memory */
// Intialize main GUI thread as STA to prevent other attempt to make it
// MTA, which will not allow ActiveX controls to be used.
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);
/* initialize the test engine */
if(!InitEngine())
goto Done;
if(!InitErrorDialogStrings())
goto Done;
if(!InStandaloneExecutable() && !DisplayRunningInEnvironmentWarning())
goto Done; // get out now
if(!ProcessPreLoginCmdlineArgs())
goto Done;
if(!CfgFile_Load())
goto Done;
if(!CfgFile_RestoreOptionSettings())
goto Done;
if(LoadGUIPanels() < 0)
goto Done;
if(!InitFileQuickList())
goto Done;
/* set initial gui state */
if(!InitGUI())
goto Done;
RunUserInterface();
retval = 0; /* normal exist status */
Done:
/* cleanup */
SeqFileList_DeleteAllSequenceFileRecords();
ExeList_DeleteAllRecords();
IconList_DeleteIconList();
SaveAndCleanupFileQuickList();
CfgFile_SaveOptionSettings();
CfgFile_WriteAndCleanupForExit();
AdaptList_DeleteAdapterList();
DestroyToolMenus();
CloseEngine();
FreeErrorDialogStrings();
return retval;
Note: Remember to #include "windows.h" at the very top of the main.c file and to include ole32.lib in your project file list in order to link in the definition for CoInitializeEx.

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

How do i use activeX to open and display a MS Excel workbook using LabVIEW?

I have created the attached vi to try to display the excel file ODSHelp.xls however when it is run nothing seems to happen, if you run it again you get a message saying that it is already open.
Attachments:
activeX_for_excel.vi ‏27 KB

You can use the activeX container to do that and one more thing is if you want to open an excel file in a front panel, try to put your data in table and I think this is more easier. Open your excel file and get the data and put it into the array and from there you can easily connect to the table. Hope this will help.

Use USERID from DB and increment it using position() to create new USERID's?

I'm trying to do the following in XSQL:
<?xml version="1.0"?>

</xsql:query>
<xsql:insert-request table="LKUP_USER" transform="/dvd/xsl/admin/createusertransform.xsl"/>
</database>and XSL:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<ROWSET>
<xsl:choose>

</xsql-error>
</database>You can see what I'm trying to do, but I can't figure out exactly how to implement it. I want to avoid the problem of conflicting USER_ID values in the Oracle DB, so I figured, pull out the max USER_ID before submission and use that when 'row-ifying' the data to create new USER_ID which are incremented based on the position() function.
Help? Is this even possible?
p.s.: I realize that I might not be able to do this because the query is not a "request". Is there another way of accomplishing this task?
p.p.s.: I don't have my XSLT book yet..
Malik Graves-Pryor

My book, Building Oracle XML Applications, has lots of XSLT material and examples :-)
You should use:
<xsql:set-stylesheet-param>
to accomplish this. Remember again that the XML that the <xsql:insert-request> sees is not the XML of your data page, but the POSTED XML. The posted XML document will not have the maxid value in it. So, instead just use a top-level stylesheet parameter in your stylesheet:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:param name="maxid"/>
<xsl:template match="/">
Rest of template here.
Refer to value of maxid in any XPath expression
in the stylesheet with $maxid
</xsl:stylesheet>then in your XSQL page, you use <xsql:set-stylesheet-param> instead of <xsql:query> like this:
<xsql:set-stylesheet-param name="maxid">
select max(user_id) from lkup_user
</xsl:set-stylesheet-param>However -- and this is not an XSQL issue, but a general database thing -- you need to be careful about concurrency issues using the SELECT MAX() trick. If two requests come in simultaneously, they will both SELECT MAX() and get the same current maximum number, then both try to insert a new user. One will (presumably) violate your primary key constraint.
It's better to use database SEQUENCES instead, so the numbers are guaranteed to be unique. To use a sequence you would just change your SQL statement above to be:
SELECT yoursequencename.NEXTVAL FROM DUAL
instead of the SELECT MAX() query.

How can I add excel pictures using activex

I would like to be able to use activex to insert an image into an excel spreadsheet. I know how to read and write data, but the chart feature is too cunmbersome and when I updated excel to 2007 most of the calls stopped working. I see that there is a pictures property/method that lets me specify an image file, but I don't know which property/method(s) to call it from.

2007 does take more time to draw the data on the chart. I am not having any problems with errors on the active X for 2007. I is much slower than 2003 I would agree. My IT group moved us to 2007 so I am stuck with it no matter how slow it is. I am trying to figure out how to get the help file back. I had these in 2003 myself. I know it has nothing to do with LabVIEW. It is an add in or some switch that you need to throw in excel to allow for this connection.

Recent loss of embedded QT movies on many page for IE7 using ActiveX object

I have many pages that allow you to select from 4 video formats including QT .mov. An example is at http://www.cwdjr.net/video4/cancanL.php . The QT object uses ActiveX when on IE only(I use Windows conditional comments) and an ordinary object for most other browsers. Until sometime very recently all of these pages worked when you select the QT file. Now QT works on none of them. I suspected the problem might be due to a very recent Windows XP update which is a large one including .NET updates and other things(K8951847) X 86. I was able to restore to a day before this update, but this did not solve the problem. Of course some portions of some updates can not be removed be restoring to an earlier time, so the result does not prove the update was not at fault.
The involved pages are mostly written in php on the server, so you will not be able to see very much by viewing the source code. To make the problem more simple to view, I made a test page for QT only and with the ActiveX object only. Thus this test page can not be viewed on most browsers that do not support ActiveX. The test page is at http://www.cwdjr.info/broadbandMedia/formatsAX/qtmovtest2.php . Since I serve pages as valid xhtml 1.1 using the correct mime type application xhtml+xml, no IE browser can view the page, since no IE browser can support xhtml served properly. Thus I have a php include at the very top for header exchange between the browser and server. If this says the page does not support the mime type for xhtml, then php using regular expressions, etc is used to rewrite the page as html 4.01 strict for the outmoded browser. Thus don't be surprised if you find some pages in xhtml and others in html when you check properties.
The ActiveX object used for QT on the test page is below:
QT MOV
(CLICK ABOVE LINK IF NO PLAYER)
<object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" width="400" height="295" codebase="http://www.apple.com/qtactivex/qtplugin.cab">
<param name="autoplay" value="true" />
<param name="controller" value="true" />
<param name="kioskmode" value="true" />
<param name="src" value="http://www.cwdjr.info/movie/cancan.mov" />
</object>
Once the page comes up on IE7, it is rather slow to respond. Then it gives:
"Web site wants to install the following ActiveX control: 'Quick Time' from 'Apple Inc'".
If you do try to install, nothing happens. In contrast to my regular pages, I added the code show above just before the start of the object. Clicking this on will bring up the QT video, but of course it is not embedded on the desired page. This may work as a temporary fix for IE. I likely can hide it from other browsers by enclosing it in Microsoft conditional comments.
I would be interested if anyone else has had such a problem recently or any ideas concerning this strange response on IE7. I am talking about viewing the page on the server. Since this is a php page it can be viewed locally only if you have a server installed on your computer and I do not. The pages with the first url example given above have operated well on IE7, Firefox, Opera, Safari for Windows, Flock, K-Meleon, Google Chrome and SeaMonkey. There are a few players that have some issues with some of the formats, but this and the fact that some players may not be installed is the reason for offering the video in 4 formats. I sometimes offer high broadband versions as well as low broadband versions.
It seems I spend more time correcting IE issues than for all of the other mentioned browsers combined.

Thanks for the reference. I use nearly no JS anymore, since it often causes problems with true xhtml served properly even when you use external script files. Often one can use php script on the server and avoid these problems. When one serves as true xhtml using the correct mime type of application/xhtml+xml, the page is parsed with a very strict xml parser rather than a loose-as-a-goose html parser. (If one serves a page written in xhtml code as mime text/html, as is incorrectly done perhaps 99% of the time, you are using only html, not xhtml, and are fooling only yourself. The page is parsed as html instead of xhtml.) The xml parser has to be very strict to account for any possible xml content. Even a single, or even several, errors often will not prevent a html page from showing, but even a single error on an xhtml page served properly will often get an error report from the xml parser rather than a view of the page. One of the most laughable examples of misunderstanding of this issue is the home page of Microsoft. It claims to be xhtml. However it is served as text/html and thus would be better written in html 4.01 in the first place. Moreover, if you validate the page as xhtml at w3c, you find hundreds of xhtml errors. If Microsoft served their home page properly as application/xhtml+xml it of course would not work on any IE browser, at least through IE7, since none of these IE browsers can handle true xhtml. In addition the page likely would not show up on any browser if served as true xhtml until all of the hundreds of xml and other errors on the page were corrected. Instead, one likely would get a very long error report rather than a view of the page.
Back to JS, document.write will not work in properly served xhtml, because it easily could produce code with XML errors. For instance it might produce code that contains an unclosed tag, which is a major xml error that can cause an xml device to malfunction. The xml parser thus rightly finds document.write as an error and prevents viewing of the page. However one often can generate the same code as document.write would produce on a browser with php on the server. The finished code is what gets downloaded to the browser, so the xml parser can check everything in the finished code rather than quess what a JS document.write might produce. And don't think you can sweep document.write under the rug by using an external JS file. The very strict xml parser finds it.
Of course embed has never been a w3c tag, but rather is a bad hangover from the browser war era, a gift of Netscape. No page that includes embed can validate as w3c xhtml or xml of any flavor, at least through xhtml 1.1. However the page may work, despite the error, if server as text/html.
All I know is that something has happened recently that has caused my problem to surface. It likely has to do with some change in the XP OS or IE browser. I have tried viewing several pages written by others that use many types of code for .mov, and all of them I have viewed that use an ActiveX embed for the benefit of IE now have the problem I mentioned. If anyone else with XP and nearly all updates, including the very recent one I mentioned, and the most recent version of QT has had this problem, I could be more confident that the problem comes from an external source. If not, it is still possible the sudden change could be something concerning a specific issue that has developed in my computer.
Again, thanks for the JS reference. Some of this likely can translate into php so I can compare how the JS and php server script I am using relate.

How to generate Word document from JSP ?

Hi,
I want to generate Word documnet from JSP. I am using Neva objects to generate Word document. Now my problem is Word doc generation code works alright as a Java application but when I place that piece of code in a JSP bean it throws an exception. The reason seems to be unavailibility of DLLs and other files of Neva in Tomcat environment. I do not want to use other complex packages like JIntegra, I would prefer any freeware solution. There is not much info. about Word document generation on POI project in Jakarta site.
Could anyone suggest way out ? Any Java examples doing the same would be of great help.
Thanks,
Akash

Hi Saurabh,
Thanks for the reply.
I have tried that too. Problem with that solution is that if you have used CSS in your JSP code MS word does not understand it and generates word doc which is not the same as HTML which JSP otherwise would have generated.

Help: sending email from JSP or MSB problem

Hi Everyone,
I have an J2EE application which sends email to a user when a user submit a form. The email is send from Jsp page and MSD using sun.net.smtp.SmtpClient class. The codes for sending email are:
String to = "[email protected]";
String from="[email protected]";
String smtpHost="the mail smtp host";
SmtpClient client = new SmtpClient(smtpHost);
client.from(from);
client.to(to);
PrintStream message = client.startMessage();
message.println("To: " + to);
message.println("Subject: a subject");
message.println("email body");
It sends email to internal email account user without a problem. However, when the email reciever's email address is a outside email account such as yahoo, I got the following error message:
Error 500: 550 not local host yahoo.com, not a gateway
This email sending system worked ok before for outsider email address in our old email server. We recerently switched to a new email server. The jsp page and MDB can no longer send email to outside account.
Any help is appreciated.
thanks

Please see this section in The J2EE 1.4 Tutorial for an example of sending email from an enterprise bean:
