Accessing excel from java code

Hello
our system uses reportNet to generate reports. When reports are generated in CSV format we have a problem:
Report consists of people (can be more than one) so under name column we have same name in more than one row. BUT if more than one name is suppose to be in the CSV report then the header (column names row) is again printed.
so for example if i requested rpeort for two names A and B (reportNet uses same template which is executed twice) then report will look like this
Name (header - column name)
A
A
A
A
A
Name (header - column name)
B
B
B
B
I want to be able to remove the second header that comes before B starts.
so i was thinking i would be able to access this excel sheet from java. and keep record of every row. If the row changes from A to B...i delete the previous row (which would end up being the second header).
Can this be done thru java. I havnt before accessed excel sheets from java so any pointers would be greatly appreciated.

Hi, well CSV is not currently an Excel file, it is a Comma Separated Values
file which can be read through Excel.
Now, if you wish to remove the header, I would purpose that you develop an
application that reads the CSV file, as it is mere text, and that it also reads
another file (lets call it confirguration.txt) in which you determine the pattern
you want to remove, then you just read your report and if a string line
matches the pattern you defined in the configuration.txt file, then you simply
erase it.
And if you keep interested in reading real Excel files (xls), I would
recommend you use POI-HSSF API from Apache.org
http://jakarta.apache.org/poi/hssf/index.html
Hope this helps, cya around.

Access ViewObject from Java code in ADF

Hello everyone,
I've got one problem with ADF, which I can't deal with on my own.
I've created web application that consists of two UI components:
- table that displays data from database (i've created entity object/view object/application module and drag onto JSF page)
- button that can refresh table / change data in it (i've got java bean method, that do some logic on view object, which is added as a action to a button)
My problem is, that i've got SQL query, for example: "select * from dept" and I want to my view object (which I've created before) displays result of this query. How can I do it?
I don't know how from a java code (in my java bean method) access a view object and execute a sql query on it? I've got some code:
ViewObject dynamicVO = this.findViewObject("VO1");
dynamicVO.remove();
dynamicVO = this.createViewObjectFromQueryStmt("VO1", "SELECT * FROM dept");
dynamicVO.executeQuery();
but the dynamicVO is always null.
Thanks for any help.

Accessing XI Tables (ABAP Stack) from Java code

Hi,
IS it possible to access tables like SXMSPMAST, SXMSPEMAS directly from Java code without the use of any RFC or BAPI in between?
Cheers,
Earlence

I think it is technically possible, as you can get access to the JDBC Connector service using J2EE's JNDI feature ... Then you can use the internal DB datasource to read data from tables (read ONLY, cuz I'm not sure it is a good idea to update data "outside" the box, and reading can also have potiential perf or stability issue) ... Some (better) methods can also exist !

Can u access Oracle9i Reports objects from Java Code?

Hi,
How can you access Oracle9i Reports (Rel 2) objects like Body, DataSource, Groups etc from Java Code?
What are the available APIs?
I went thru the APIs at http://otn.oracle.com/products/reports/htdocs/getstart/docs/Javadocs/oracle/reports/plugin/definition/package-summary.html
However various constructors stated in these APIs are using classes from "oracle.reports.definition" package which are difficult for me to locate.
For eg. Report constructor is using oracle.reports.definition.RWReport and there is no API documentation available for RWReport class.
Please suggest me the site for the above APIs or the method to get a reference to "Report" instance.
Thanks
Rakesh.

Thanks Tugdual for your quick reply.
Thats exactly what I am trying to do. I want to develop a utility which can have a subset of Report Developer's functionality.
Currently using Reports Developer & Report Wizard, I can create a report by providing SQL statement and few parameters (like Report Style, Calculated Fields, Template file etc). I want to put all these parameters in a XML file and run my java utility (based on the APIs which I am looking for) which will use these XML parameter file and generate a '.rdf' file.
Also, could you please suggest me the site for oracle.reports.definition package API or the way to get a reference to oracle.reports.plugin.definition.Report instance.
Thanks,
Rakesh

Clear the Filter Criteria from java code programmatically

Hi All,
I am using jdev version 11.1.1.6.0.
I do have ADF table for which I have added filter to each column .
I created table using java class data control.
Filter is working Fine .
My use case is-
When I click on search button data is populated in table.
When anybody enters filter value in column suppose product and hit enter ,it filters data.
if he clears and do not hit enter key and search again then it does not show all data it only show filtered data.
So how can I programmatically clear all filters so on click of search it will show all the values not filtered values.
I have not used default Filter Behavior.
Please check below code for reference
<af:table value="#{bindings.AfMyAccOrderStatusHistorySearchVO.rangeSet}"

Jintegra problem - accessing Matlab from Java??

Hi:
Sorry if this post doesn't belong here!!
I am accessing Matlab from JAVA using JIntegra for COM. I tried running the example in their website.
(http://j-integra.intrinsyc.com/support/com/doc/other_examples/Matlab.htm)
I have also posted the example below. I am using their trial version and have included all the jars as said. I get the an unexpected output (all zero's) for reading a variable in the matlab workspace. I don't understand why I get this. Can anyone let me know if this runs for you??
Thanks
Pavan
Example code from Jintegra website:
public class MatlabExample {
public static void main(java.lang.String[] args) throws Exception {
try {
// DCOM authentication: Make sure NT Domain, NT User, NT Password are valid credentials.
// Uncomment this line if MatlabExample.java remotely accesses MATLAB :
// com.linar.jintegra.AuthInfo.setDefault("NT DOMAIN", "NT USER", "NT PASSWORD");
// Create the MATLAB object
// Specify host name or IP address of MATLAB machine as parameter if
// MatlabExample.java remotely accesses MATLAB.
// mlapp.MLApp mlApp = new mlapp.MLApp("123.456.789.0");
mlapp.MLApp mlApp = new mlapp.MLApp();
String result = mlApp.execute("a = [1 2 3 4; 5 6 7 8;]");
System.out.println("Execute result is " + result);
double mreal[][] = new double[2][4];
double mimage[] = new double[0];
mlApp.getFullMatrix("a", "base", new Object[]{mreal}, new Object[]{mimage});
for (int i = 0; i < 2; i++) {
for (int j = 0; j < 4; j++) {
System.out.println(mreal[i][j]);
} finally {

[JDBC][ODBC] How to compact access database from Java ?

Hello,
I'm developping a java applcation wich is connected to an MS Access file database.
For now, I don'y compact it but it would be better.
So How can I compact an access database from Java ?

Hi ypiel,
Try this:
1) Download JETCOMP.exe (freeware from Microsoft);
2) Put the following code in your app (assuming your database file name is: "DB.mdb"):
try {
File current = new File("DB.mdb");
File backup = new File("BACKUP.mdb");
if (current.renameTo(backup)) {
Runtime.getRuntime().exec("jetcomp -src:BACKUP.mdb -dest:DB.mdb");
} catch (Exception e) {
System.out.println(e.getMessage());

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file
