Java API for webcams and Electrical Engineering

Hi,
Does anyone know of and API's that allow access to:
- Webcams, so that you are able to monitor a webcam and access the images etc etc
- Electronic circuit boards, e.g. monitor hardware, such as a processing plant whereby you can monitor output, input etc
Basically a java interface to hardware, i looked at the javacomm api, but this only allows basic functionality as far as i am aware.
Essentially, i need to monitor production faciltiies interfacing to a java environment so that hardware can be controlled and monitored.
Any suggestions people ?
Thanks

The Java Twain API from http://www.gnome.sk is designed to connect to a camera (or scanner) directly from the java application. You can comunicate with the camera, snap images, save them, ...
If you just want to see how Java Twain works:
- java (1.2 or higher) has to be installed on your computer
- a scanner or camera has to be installed on your computer
- download the trial package from http://www.gnome.sk
- unzipp it
- go to the examples directory of the unzipped package
- doubleclick the runExampleShow.bat (for Windows) or runExampleShow.sh (for MacOS) file
This will pop up the Twain Source Selection user interface. There, all your scanners and cameras which do have a twain driver should be listed. Select one of them. The user interface of the selected scanner (camera) will appear. Confirm the scanning (you can set the scanning parameters first). The scanned image will be displayed in a separate window. To end the application, close that window.
Running different examples, you can test scanning with hidden UI, saving the scanned image, using ADF, ...
If there are any problems, inquire at the technical support [email protected], I am a member :)

Java API for Adobe Flex(AIR and Browser)

Hello Community,
Sometime ago i started the project located at: : http://code.google.com/p/gwt4air/ , wich primary goal was to bring another approach on writing AIR application by providing a Java API for the AIR API. On top of that i added support for PDF and Excel generation using Java.
I m glad to announce that the project will now add support for the Flex Framework
I wrote a post about it on the main page.
The Idea behind it is to give Java Developers a more simple way to write Flex Application by leaveraing a swing like API.
I hope this project will be a good alternative to the MXML+ ActionScript approach and looking for people willing to join the project.

Alain

Good question, I'd like to know this myself. 4.5 has a huge number of changes since 4.0.

Java API for running entire ".sql" files on a remote DB ( mySQL or Oracle)?

Hi,
Would anyone happen to know if there's a java API for executing entire ".sql" files (containing several different SQL commands), on a remote database server ?
It's enough if the API works with MySQL and/or Oracle.
Just to demonstrate what i'm looking for:
Suppose you've created sql file "c:/test.sql" with several script lines:
-- test.sql:
insert into TABLE1 values(3,3);
insert into TABLE1 values(5,5);
create table TABLE2 (name VARCHER) ENGINE innoDB; -- MYSQL specific
Then the java API should look something like:
// Dummy java code:
String driver="com.mysql.jdbc.Driver";
String url= "jdbc:mysql://localhost:3306/myDb";
SomeAPI.executeScriptFile( "c:/test.sql", driver, url);
Thanks.

No such a API, but it's easy to parse all sqls in a file, then run those command:
For instance:
import java.sql.*;
import java.util.Properties;
/* A demo show how to load some sql statements. */
public class testSQL {
private final static Object[] getSQLStatements(java.util.Vector v) {
Object[] statements = new Object[v.size()];

Image not displayed in pdf generated using Java API for Forms service

Hi,
I am creating a pdf document using Java API for Forms Service.
I am able to generate the pdf but the images are not visible in the generated pdf.
The image relative path is coming in the xml as defined below. The images are stored dynamically in the Livecycle repository each time a request is fired with unique name before the xml is generated.
<imageURI xfa:contentType="image/png" href="../Images/logo.png"></imageURI>
Not sure if I need to specify specify specific URI values that are required to render a form with image.
The same thing is working when I generate pdf document using Java API for Output Service.
As, I need to generate interactive form, I have to use Forms service to generate pdfs.
Any help will be highly appreciated.
Thanks.

Below is the code snippet:
            //Create a FormsServiceClient object
            FormsServiceClient formsClient = new FormsServiceClient(myFactory);
            //Specify URI values that are required to render a form
            URLSpec uriValues = new URLSpec();
                              // Template location contains the whole rpository path for the form
            uriValues.setContentRootURI(templateLocation);
           // The base URL where form resources such as images and scripts are located. Whole Image path is passed in BaseUrl in the http format.
                  String baseLocation = repositoryPath.concat(serviceName).concat(imagesPath);
                              uriValues.setBaseURL(baseLocation);
            // Set run-time options using a PDFFormRenderSpec instance
            PDFFormRenderSpec pdfFormRenderSpec = new PDFFormRenderSpec();
            pdfFormRenderSpec.setCacheEnabled(new Boolean(true));
            pdfFormRenderSpec.setAcrobatVersion(com.adobe.livecycle.formsservice.client.AcrobatVersio n.Acrobat_8);
                              //Invoke the renderPDFForm method and write the
            //results to a client web browser
            String tempTemplateName =templateName;
            FormsResult formOut = formsClient.renderPDFForm(tempTemplateName,
                                          inXMDataTransformed,pdfFormRenderSpec,uriValues,null);
            //Create a Document object that stores form data
            Document outputDocument = formOut.getOutputContent();
            InputStream inputStream = outputDocument.getInputStream();

Java API for Error Handling

There are some common error tables storing error IDs information ( IDs like error type, project id, interface id, message id etc.) in Operational Database (is not on source or target system) which we have to update using java API. We need to call java API (java code) whenever error occurs. We have to provide all the IDs to this function and then API will take care of DB updating. We can call java API in mapping program by creating user-defined java function, this will trap all the errors which are in source file as well as in mapping and mapping lookup. Query is:
A- A- Do we have any other place after the mapping to call this java API and trap the errors through it?
B- Can we call Java API using BPM and pass error IDs to it.

Hi Anand,
You Have to write Module For that(if you wanna call Java API after Mapping)at the receiver.
To write Module Here is a link which will help you in.....

EWS JAVA API for availability is giving only 10 suggested times in a particular day

I'm using EWS JAVA API for seeing the availability of contacts who had shared their calender with me. Here in the suggested timings, I can able to see only 10 suggested timings even though there can be more than 10 suggested slots.
I would like to check is there any limit on suggested times ?
API is also giving quality of timing like "Good", "Excellent" on what basis this is decided ?

You can specify the maximum number of suggestions per day using the MaximumResultsByDay parameter (http://msdn.microsoft.com/en-us/library/office/aa565641(v=exchg.150).aspx).
The quality is determined based on how many attendees are available and is influenced by the GoodThreshold:

7) Open "SAPSHRJAVxx_x-xxxxxxxx.SCA" file by "WINRAR" and unzip on your local laptop.
8) After unzip you will get several zip files under folder "BUILDARCHIVES"
9) Find "crmshrjavadoc" file inside folder "BUILDARCHIVES"
10) Unzip "crmshrjavadoc" file and you will get "javadoc.ppa" file
11) Rename "Javadoc.ppa" file to "Javadoc.zip"
12) Unzip "Javadoc.zip" file which we just rename in step 11.
13) you will get folder "Docs". This folder contain actual "javadoc.zip" file
14) Unzip above file and you will get Java API Documents for ISA 5.0 or ISA 6.0 or ISA 7.0 depends on "SAPSHRJAVxx_x-xxxxxxxx.SCA" version and SP level.
I just got ISA Java Doc by following above steps. It looks 14 step but once you download SCA file it will take only 2-3 minutes.
I am sure you will get Standard Java API for ISA just like ISA 4.0
Please let me know if you face any problem.

Question about Java API for XML schema?

Hello, everyone!
I am looking for a java api for XML schema. I hope the API is capable for parsing the structure of element
or complextype declarations in XML schema. So for example, if I specify a name of an element or
complextype defined in a schema, the name, dataype and other constraints of contained child elements can be returned.
Does anyone know if there exists such a paser?
Thanks very much!

Essbase Java Api for Filters

Hi all,I am using Java Apis for Essbase 7.1. I am using following Api for Database Filters to get the "Access Level". IEssCube.IEssSecurityFilter.getAccess()Gets the default filter access level. However the doumentation does not provide any information about the value returned by this Api and its meaning.Please can you tell what each integer value returned by this Api represents..Thanks.

I believe the values are documented in IEssCube.EEssCubeAccess.Be aware the security filter class is marked 'for future use' in the docs:The IEssSecurityFilter is cube security filter. (FOR FUTURE USE). That may mean it is not fully tested or perhaps not even fully implemented.Tim TowApplied OLAP, Inc

Java mapping for Remove and Add of DOCTYPE Tag

Hi Mahesh,
I understand, you are using extended Receiver Determination using Operational Mapping (which has Java Mapping). And, there is an error message u201CError while determining root tag of XMLu201D, when you are doing configuration test.
Can you please test, the Operational Mapping (which has Java Mapping) separately in ESR, with payload which is coming now. It should produce a XML something like this [Link1|http://help.sap.com/saphelp_nwpi711/helpdata/en/48/ce53aea0d7154ee10000000a421937/frameset.htm]

If it is not (I Think it will not), then there is some problem in Java Mapping coding. Please correct it. Last option, if your Java code is small in length; you may paste it here, so that we can have a look at the cause of issue.

InterMedia Java Classes for Servlets and JSPs and Netscape

I am using the interMedia Java Classes for Servlets and JSPs to upload and retrieve multimedia data. I have found that it is much more performant in Internet Explorer (5.5) than in Netscape Communicator (4.7). In fact, I cannot upload images larger than 10K at all using netscape. However, the same image can be uploaded into the same application using IE. Is this a known issue?
Thanks in advance.

Hi,
We have successfully uploaded multimedia data in the giga-byte range (Quicktime and AVI files) at the same speed with both the Netscape (4.7n) and MS IE (4.n and 5.n) browsers. One thing we have noticed is that its very important to set the manual proxy settings correctly if you have an environment with a proxy server. If you don't, then uploads can go via the proxy server and, for some reason, that seems to take considerably longer. For example, suppose you are in the www.xyzco.com domain and are connecting to a host named webserver.www.xyzco.com, then specify webserver and webserver.www.xyzco.com (to cover both cases) in the "Do not use proxy servers for..." box in the manual proxy server configuration screen. Also, if you're using a tool such as JDeveloper that uses the host IP address in the debugger environment, then you also need to add the numeric-based (nnn.nnn.nnn.nnn) IP address to this list.
Hope this helps.
In order to better understand the variety of ways in which our customers are using interMedia, we'd be very interested in knowing a little more about your application, the interMedia functionality that you are using, and how you are developing and deploying your application. If you are able to help us, please send a short email message with some information about your application, together with any comments you may have, to the Oracle interMedia Product Manager, Joe Mauro, at [email protected] Thank you!

Hi Satosh Sutar,
Based on the description, you got the error message when you update the apps from version 1.0 to 1.1.
From the error message, it seems the menifest include some settings no allowed in the new version. Would you mind sharing more detail about how you update the project?
And here is an article about updating apps for Office and menifest schema files in the project for your reference:
