This is a new problem with jdk1.4 when compiling with tomcat.
The solution is to ensure that any classes in WEB-INF/classes are in a package structure and the relevant jsp calls the same using the package name.

Help: OJSPC can not compile the JSP with struts tag

Hi,
I am trying to precompile the JSP page with EAR package but OJSPC can not parse the Struts tags.
I always get oracle.jsp.parse.JspParseException:
Error: org.apache.struts.taglib.html.MessgesTei while reading TLD /WEB-INF/tld/struts-html.tld
My OC4J version is 10.1.3.2 and I did tried putting the struts-taglib.jar to /opt/oracle/product/app10g/j2ee/home/jsp/lib or /lib/taglib
but still do not work.
Can anyone tell me how to configure the OJSPC and let it support customerized taglibs?
Thanks a lot!

Why my JSP can not recogonize the JSTL tag??

My hello.jsp code is like follows:
<%@ include file="/WEB-INF/jsp/include.jsp" %>

<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>

</html>
When I start the tomcat server and run my application ,the tomcat shows the error message:
org.apache.jasper.JasperException: /WEB-INF/jsp/hello.jsp(5,17) No tag "" defined in tag library imported with prefix "fmt"
But I do import the tag library, why it still show the error that No tag "" defined in tag library ???

Ok, now I have specify the <taglib> in my web.xml file and I have paste the fmt.ltd under WEB-INF/ like this:
<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/fmt.tld</taglib-location>
</taglib>
<taglib>
     <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
     <taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
When I re-deploy my application and start the tomcat server, the error message now is still :
jsp/hello.jsp(6,17) No tag "" defined in tag library imported with prefix "fmt"
My include.jsp is used to import all the libraries that needed,like follows:
<%@ page session="false"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>
My hello.jsp is like follows:
<%@ include file="/WEB-INF/jsp/include.jsp" %>
<html>
<head>
<title><fmt:message key="title"/></title>
</head>
<body>
<h1><fmt:message key="heading"/></h1>
<p><fmt:message key="greeting"/> <c:out value="${model.now}"/></p>
     <h3>Products</h3>
<c:forEach items="${model.products}" var="prod">
<c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>
</c:forEach>
</body>
</html>
Why? I just import the fmt.ltd, everything seems correct, why this error? It seems that tomcat can not find the "fmt" prefix in tag library.
Please Help:(

Strange scenario,Oracle can not display the data in mysql correctly

I use Heterogeneous Service+ODBC to achieve "oracle access mysql"(any other method?),and now i find Oracle can not display the data in mysql correctly:
-------mysql------------
mysql> create table tst(id int,name varchar(10));
Query OK, 0 rows affected (0.00 sec)
mysql> insert into tst values(1,'a');
Query OK, 1 row affected (0.00 sec)
mysql> select * from tst;
------------+
| id | name |
------------+
| 1 | a |
------------+
1 row in set (0.00 sec)
mysql> show create table tst\G
*************************** 1. row ***************************
Table: tst
Create Table: CREATE TABLE `tst` (
`id` int(11) DEFAULT NULL,
`name` varchar(10) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
-------------oracle ------------------
SQL> select count(*) from "tst"@mysql;
COUNT(*)
49
SQL> select * from "tst"@mysql;
id
1
SQL> desc "tst"@mysql;
Name Null? Type
id NUMBER(10)

You can make the following query on the result page:
"select * from the_table where movietitle = ? and cinema = ?"
then you set movietitle and cinema to those which the user selected. If the resultset contains more than 0 rows, that means the movie is available.
Below is the sample code, it assumes you have a connection to the database:
PreparedStatement stat = myConnection.prepareStatement("select * from the_table where movietitle = ? and cinema = ?");
stat.setString(1, usersMovieTitleSelection);
stat.setString(2, usersCinemaSelection);
ResultSet res = stat.executeQuery();
if (res.next()) {
out.print("The movie is available");
} else {
out.print("The movie is not available");
}Now just add that to your JSP page. Enjoy ! =)

Can not access the Instance Data of a Singleton class from MBean

I am working against the deadline and i am sweating now. From past few days i have been working on a problem and now its the time to shout out.
I have an application (let's call it "APP") and i have a "PerformanceStatistics" MBean written for APP. I also have a Singleton Data class (let's call it "SDATA") which provides some data for the MBean to access and calculate some application runtime stuff. Thus during the application startup and then in the application lifecysle, i will be adding data to the SDATA instance.So, this SDATA instance always has the data.
Now, the problem is that i am not able to access any of the data or data structures from the PerformanceStatistics MBean. if i check the data structures when i am adding the data, all the structures contains data. But when i call this singleton instance from the MBean, am kind of having the empty data.
Can anyone explain or have hints on what's happening ? Any help will be appreciated.
I tried all sorts of DATA class being final and all methods being synchronized, static, ect.,, just to make sure. But no luck till now.
Another unfortunate thing is that, i some times get different "ServicePerformanceData " instances (i.e. when i print the ServicePerformanceData.getInstance() they are different at different times). Not sure whats happening. I am running this application in WebLogic server and using the JConsole.
Please see the detailed problem at @ http://stackoverflow.com/questions/1151117/can-not-access-the-instance-data-of-a-singleton-class-from-mbean
I see related problems but no real solutions. Appreciate if anyone can throw in ideas.

Help! pagecentent.setAttributes, IE can not open the site

Hi there,
I have some scriplets in my jsp file.
I the scriplets I used pagecontent.setAttribute("varname", varvalue) so that i can use varname in my jstl code.
My jsp file is about getting some image file and print its string format.
I run the url and it works at first, but after load the page several times, I got the error messge:
Internet Explore can not open the site http://....
I click refresh, sometime it works, some time not. The more times I load the page, the more often the error shows up.
Does anybody have any ideas about this error?
Does mix scriplet var with jstl var often cause problem?
Thanks a lot.

i think you might have to give a bit more detail...its easy to mark this as a IE configuration problem the way you have it....caching? does it behave differently if you 'click refresh' or hit F5? seems stupid but F5 always does a true page refresh. links and the refresh button seem to grab from cache even when they're not supposed to. i've also dealt with annoying proxy servers that ignore the response.setDateHeader ("Expires", 0); directive.
i apologize if i'm on the wrong track, but any sort of java errors would usually show up in a log or something...see if you can find that to debug any syntax problems.

My Mac G-4 OS X will not image an icon of the zip disk with I inserted into my computer's built-in Zip Drive, therefore I can not remove the zip disk from my computer. What can I do?

My Mac G-4 OS X will not image an icon of the zip disk with I inserted into my computer's built-in Zip Drive, therefore I can not remove the zip disk from my computer. What can I do?

Thanks Old Comm Guy, BD Aquam and Texas Mac Man for youradvice and reply to my question
and problem with my Zip Drive. However:
    1. Depressing mouse buttonon start up did not eject the zip disk.
    2. To examine front of zipdrive, I had to remove many screws and several plastic case
         coverings. Upon doing thatI discovered that, unfortunately, there is no whole in front
          of mybuilt-in zip hardware drive for me to insert a paper clip to manually eject zipdisk.
      3. I went to the Utilities folder in myMac OS X Application folder, but I could not find
           theiomega zip drive in there.
Also, I did go into my "9" System folder and thento the Extensions folder within it and did find an icon of an
Iomega Driver. When double clicking on it a window came upstating I was opening the application
"ColorSync Extension" for thefirst time, and asking if I was sure I wanted to open this application.
Uponclicking open nothing happened - nothing opened.
I also went into the "System X" folder>Libraryfolder>Extension folder>IomegaSAM.ket icon and double
clicked on it and asmall window opened stating "Compiling file List", however nothingopened it just
continued to compile, so I closed it.
Within my Mac OS X HD> Applications>Iomega folder>Iomega Tools.app a smallwindow opened up
with several options (Erase, Protect, Disk Info and DriveInfo). Clicking on the Drive Info a message says:
"No Iomega Drives or noIomega Driver found. Therefore, Ihave gone to Mac, Iomega and other websites
trying to find a Driver for thebuilt-in Zip Drive in my Mac G-4 OS X 10.4.11, but have not really found anythat work.
CAN ANYONE TELL ME IF THERE IS A WEBSITE WHERE I CANDOWNLOAD A NEW DRIVER FOR MY ZIP DRIVE?

Can not get the parameter?

I use a form to upload files,
like this:
<form name="gdform10" action="upload.jsp" ENCTYPE="multipart/form-data" method="post">
<input type="hidden" name="picName" value="wxds.jpg">
<input type="file" name="file">
<input type="submit" name="savePic" value="modify">
</form>
but I can not get the parameter picName in the upload.jsp,
like :
String pname = request.getParameter("picName");
but pname is null.

Hello,
In Jsp, if you want to upload file, you can't directly use "request.getParameter()".
There're two company provide components for you and it's free.
First is jspsmart company, it offer jspsmartUpload component and link is
http://www.jspsmart.com
Second is o'reilly, it offer MultipartRequest component and links is http://www.servlets.com/cos/javadoc/com/oreilly/servlet/MultipartRequest.html
for example, you use oreilly component.
<%@ page import="com.oreilly.servlet.MultipartRequest" %>
String saveDirectory = "c:\\Upload\\";
int maxPostSize = 5 * 1024*1024;
MultipartRequest multi= new MultipartRequest(request,saveDirectory,maxPostSize );
Enumeration filesname = multi.getFileNames();
while(filesname.hasMoreElements()){
String name = (String)filesname.nextElement();
FileName = multi.getFilesystemName(name);
File f = multi.getFile(name);
String ContentType = multi.getContentType(name);
ps. above codes is from book named "java server pages tech reference"

Why MS JVM can not fine the classpath

I have a applet and it's working fine with Sun JRE,but when I use MS JVM I always get error like can not fine the classpath,I alreday have created jar for all the applet class file and I have defined codebase and code ,using applet tag. I want to use Java1.1.
I use NetBeans 3.6 compile the whole applet. and Can you tell me how to do?

The applet probably includes code that is not supported by, or compatible with, the MS jvm. That error is a typical response to this cause.
Try using the compiler option "-target 1.1". If that doesn't work, you could download an old jvm from Sun's archive page and recompile with it.
If that doesn't work, then you have to rewrite the applet to use only code that can be run by the MS jvm.
Be aware that there are differences between MS and Sun jvm's, so it may have to be rewritten no matter what.

Can not change the field property - 10gR2 reports crashing on Linux :(

All I want to do, is to change one field's property from NUMBER to DATE in the property palette. It does not allow me to do it (not east like forms). I can not change the field property - 10gR2 reports keep crashing on Linux :(
I don't know if this is a Linux specific iDS issue, or a generic one.
What are the proper steps to change one field (in my query, the field name is ptime, it was defined as a number field originally, and now I need to change it to DATE and apply the proper format mask). The matching database field definition was modified from number to date.
very frustrating...
Any input is appreciated.

nop, did not change anything in the select statement at all. Just selected the related query under the data model (in the navigator), then selected the related query from within the property panel, connected to the db, then from the related navigor menu selected compile all, when the related query was highlighted (selected). Then I saved it, checked the groups, and bingo - the datatype was changed from number to date. Then I went to the related object under the page layout and applied the format mask (that was another funny story). And it worked. It is not as flexible as the forms for sure - pain in the a.. And I still don't know why Reports Builder keeps crashing on Linux - have no problems with Forms Developer on Linux at all. It is a certified RH platform with all the required libs, rpms, etc installed. I am certain it is not an installation issue. Maybe I should check Metalink and apply if an iDS 10gR2 patch exists for reports.

I have a compaq 6200 pro i can not find the driver for SM bus controller.

I down graded the 6200 pro with the i3 chip to winXP and now I can not find the driver for the SM bus controller does this system have a sm bus controller?

Hi: Please click on the device in the device manager. Then click on the details tab. Post the top string of characters you see. Those will identify the type and model of the missing device and I can send you the link to the drivers. It is either your AMT driver, TPM driver or IMEI driver. In the meantime, install the chipset driver and reboot if you have not done so already. http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=5037900&prodNameId=5037902&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=vc-88640-1 Paul

Data blocks in forms 6i, can not see the data

i have built an application in forms with some data blocks. the blocks a connect to some tables in the db. i have built them connectd as "system". but when i run the applicatio as user x i can do select, insert, update, delete, but i can not se the records in the datablocks (they are empty), but i can do all transactios. why?

First of all, developing from the System schema is not a good idea.
Who owns the tables your form is connecting to? The table owner should create a public synonym for each table name, and also needs to grant user x access to the table.
