Invoking MS Excel from Java

HI,
I'm trying to create a standalone application that would need to logon in a database.If the user is a valid one, the user can then choose which table he wanted to update. All the rows of the column will be shown in an excel format. (the program will invoke Excel to show all the records in that table). From that, the user can edit the content and after saving it, data in the databse will also be updated.
Is there any Java API that I can use to make this application possible?
Thanks,

Invoke beanshell methods from java

Hello
I'm learning beanshell and using it to write scripts that are ran in JDK 6.
My question is how to invok beanshell methods from java source codes.
My codes is:
import javax.script.*;
public class InvokeFunctions {
public static void main (String[] args)throws ScriptException, NoSuchMethodException
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine bshEngine = sem.getEngineByName("beanshell");
String script = "public void sayHello()"+"{print (\"sayHello() is a method in bsh script\");}";
bshEngine.eval(script);
Invocable inbshEngine = (Invocable)bshEngine;
inbshEngine.invokeFunction("sayHello");
I defined a method "sayHello()" using beanshell, but i just can't invoke it in Java.
I got an error msg said:
Exception in thread "main" java.lang.IllegalAccessError: tried to access method bsh.NameSpace.getThis(Lbsh/Interpreter;)Lbsh/This; from class bsh.engine.BshScriptEngine
Any one has any idea about it?
Thanks

Look at the Javadoc documentation of IllegalAccessError. It says:
Thrown if an application attempts to access or modify a field, or to call a method that it does not have access to.
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
Maybe recompiling all your sources (make sure you delete all existing *.class files) will help?

Invoking C# WS from java axis proxy generated from the same WSDL

I am trying to transparently use the same java interface for invoking a java axis WS and a C# WS generated from the same WSDL interface.
I believe the problem may be that the .NET web service which is generated from the WSDL file, is dynamically exposing a WSDL file which is not exactly the same as the original WSDL used to generate the abstract C# class with "wsdl.exe"
When I try to invoke the C# web service with the java axis client I get the error message:
"Server did not recognize the value of HTTP Header SOAPAction: ."
Any suggestions about how to be able to use the same client interface from java, to invoke a C# web service and a java axis web service supporting (i.e. generated from) the same WSDL ?

The JNI method name in the .h file is different to that in the .c file.

Invoking bpel process from java in oracle soa/bpm 11g

Hi,
We have some java code to invoke bpel process in oracle BPM 10g following the instructions in http://download-east.oracle.com/docs/cd/B14099_19/integrate.1012/b14448/invoke.htm.
Basically the steps are:
1) get a Locator (com.oracle.bpel.client.Locator)
2) get IDeliveryService (com.oracle.bpel.client.delivery.IDeliveryService) reference from locator
3) call IDeliveryService method request or post with input message and get the response back.
Recently we want to migrated from oracle bpm 10g to oracle soa/bpm 11g. But I can not find the similar API in 11g. It seems now some adapter/binding need to be added in exposed service lane in soa composite view, for example, ADF-BC, direct binding etc, in order to allow java to invoke a bpel process. Here are two very useful links from Edwin about the detail how this is implemented.
http://biemond.blogspot.com/2009/11/invoking-soa-suite-11g-service-from.html
http://biemond.blogspot.com/2009/11/calling-soa-suite-direct-binding.html?showComment=1285198033913#comment-c1055322845511794252
My question is:
1) what are the choices and the official/best way to invoke a bpel process in oracle soa/bpm 11g from java?
2) does user need to add an adapter/binding in exposed service lane in order to let the bpel service be called in java?
3) what is the real difference between a bpm application and soa application in 11g?
I will really appreciate any expert's opinion.
Thanks,
Bin

Thanks for your reply and confirmation, really appreciate it.
Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.

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.

Excel from JAVA or C++ -- Urgent -- help

Hi
I know it might not be possible, but i want to use couple of Financial Functions which excel provides within itself.
Is there anyway i can use them from my JAVA or C++ code ?
In short, would it be possible to call excel functions from JAVA or C++ code
TIA
Vikram

Actually you can... In quite a few different ways. You can access any COM or OLE object in windows from within java by using the Java/COm bridge, or purchasing shrink wrapped products... The links are below:
These people provide some very cool solutions for java. This link is specifically for excel.

Invoking command prompt from Java

I would like to invoke dos prompt from my java application. The above code is not working. What could be the problem? I am using Windows XP m/c with netbeans.You didn't give it hands and feet, i.e. you can't expect the cmd.exe process to fire up a terminal for its input and output; you have to do that yourself. Read all about the Input- and OutputStreams of those sub-processes in the API documentation of the Processs class.
