Ye Olde Java Communickation API

You're not seriously telling me that the JCA is written in pre-Collection Java? Enumerations... I remember those... snarl

Compatibility with previous versions...I don't have a problem with that, but surely they could provide methods that use the current API?

MQSeries 5.2 still support old Java API 1.1.8 ?

We are using MQseries 5.1 and java 1.1.8. now we are upgrading to MQseries 5.2, do we need java 1.2 or 1.3.
does the MQSeries 5.2 still support old Java API 1.1.8 ?
thanks
Rupinder

Not according to the documentation which says MQSeries 5.2 has a dependency on JDK1.2.2 or later.
Having said that, I have managed to get some JMS functions to work under JDK1.1.8.
I have had a problem when using JMS to GET a message from our mainframe QMgr but not from our Unix QMgr. This runs ok when using JDK1.2.2,

How to convert old Java Servlets to OSGi "Servlet" Bundles

Hello I'm looking for some help/insight on the best way to convert some of our old Java Servlet code into new OSGi Bundles that can be accessed as servlets. I'd like to be able to install the new bundles then access them on one of our CQ instance using something like "/servlet/servlet_name".
So far I've been able to create a new bundle, and install it into CQ but I haven't been able to access the bundle at the servlet mapping URL that I would expect. So far what I've found online has lead me to believe that I need to use the Felix Annotations to describe my servlet.
@Component(immediate = true, metatype = true, label = "Servlet Name")
@Service
@Properties({
    @Property(name = Constants.SERVICE_DESCRIPTION, value = "Servlet Name"),
    @Property(name = "sling.servlet.methods", value={"GET"}),
    @Property(name = "sling.servlet.paths", value = "/servlet/my_servlet_mapping"),
    @Property(name = Constants.SERVICE_VENDOR, value = "VendorName")
public class TellAFriend extends HttpServlet {...
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException
Once I have this installed, and running without an error in the logs for CQ I tried to go on my local instance to http://localhost:4502/servlet/my_servlet_mapping but I only get 404 Resource Not Found errors. I've even gone to the Sling Resource Resolver and it doesn't resolve to anything either.
Is there more than the Servlet Information need into the Annotations to convert "old" code into a new OSGi Servlet Mapped Bundle?

I must be missing something else configuration wise since I created a new Servlet basically using the code you provided above. I deployed it as part of the bundle that I'm trying to create.
The bundle installs and stars fine but I still can't access the servlet. Are there CRXDE based configurations that are requried too to configure Servlets.
Here's my test servlet file. I tried going to http://localhost:4502/servlet/TestCQServlet and just get the same 404 error I'm getting for the other 2 Servlets Java classes in my Bundle.
import java.io.IOException;
import javax.servlet.ServletException;
import org.apache.felix.scr.annotations.sling.SlingServlet;

P.S: CHECKING !!
STEP 1.
First compile and execute the PROGRAM 1 with your USERNAME & PASSWORD. This will send a mail to your own account.
STEP 2.
Now compile both PART 1 & PART 2 of PROGRAM 2. Then, execute PART 1 - Main.java. This will retrive the mail sent in step 1. njoy! :)
In future, I hope this is added to the demo programs of the Java Mail API download package.
This is for 3 main reasons...
1. To prevent a lot of silly questions being posted on this forum [like the ones I did :(].
2. To give the first time Java Mail user with a real time working example without code modification [code has to use command line args like the demo programs - for instant results].
3. Also, this is what google has to say..
"The Gmail Team is committed to making sure you always can access your mail. That's why we're offering POP access and auto-forwarding. Both features are free for all Gmail users and we have no plans to charge for them in the future."
http://mail.google.com/support/bin/answer.py?answer=13295
I guess bshannon & Java Mail team is hearing this....
Again, Hurray and thanks for helping me make it!! cheers & no more frowned faces!!

Performance issue with Business Objects Java JRC API in CRXI R2 version

A report is developed using java JRC API in CR XI release 2. When I generate the report in the designer, it took less than 5 seconds to display the results in crystal report viewer inside the designer. But in the QA environment, when I generate the same report from the application, it takes almost 1 to 1.5 minutes to display the same results in PDF. I also noticed that if the dataset contains bigger volume of data, then the reports are taking even longer almost 15 to 20 minutes.
While generating the report from the application, I noticed that most of time is taken during the execution of the com.crystaldecisions.report.web.viewer.ReportExportControl Object method as shown in following line of code
exportControl.processHttpRequest(request, response, context, null)
We thought the delay in exporting the report to PDF might be the layout of the report and data conversion to PDF for such a bigger volume of data.
Then we investigated the issue and experimented quickly to generate the same report with same result set data from the application using XML, XSL and converted the output XSL-FO to PDF using Apache FOP (Formatting Objects Processor) implementation. The time taken to export the report to PDF is less than 6 seconds. By doing this experiment, it is proved that the issue is not with conversion of data to PDF but it is the performance problem with Business Objects Java JRC API in CR XI R2.
In this regard, I searched for the above issue in the SAP community Network Forums -> Crystal Reports and Xcelsius -> Java Development -> Crystal Reports. But I did not find any answers or solutions for this kind of issue in the forums.
Any suggestion, hint in this matter is very much appreciated.

Ted, The setReportAppServer problem is resolved. Now I could able to generate the report with hardcoded values in the SQLs in just 6 seconds where as the same report was generated in CRXI R2 in 1 minute 15 seconds as mentioned in the earlier message.
But, our exisiting application passes the parameter values to the SQLs embedded in the report. For some reason the parameters are not being passed to the report and the report displays only the labels without data.
As per the crj 12 samples codes, the code is written as shown below.
1. Created ReportClient Document
2. SetReportAppServer
3. Open the report
4. Getting DatabaseController and switching the database connection at runtime
5. Then setting the parameters as detailed below
ParameteFields parameterFieldController = reportClientDoc.getDataDefController().getParameterFieldController();
parameterFieldController.setCurrentValue("", "paramname",paramvalue);
parameterFieldController.setCurrentValue("", "paramname",paramavalue);
byteArrayInputStream = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
6. Streaming the report to the browser
Why the parematers are not being passed to the report? Do I need to follow the order of setting these parameters? Did I miss any line of code for setting Params using crj 12?
Any help in this regard would be greatly appreciated.

How to print a document in reverse order using Java Print API ?

Which method implementation of Pageable interface should return the page number ?w.r.t. your first question: don't return that number but return page n-1-i when page i is requested; your document will be printed in reverse order. Your class should implement the entire interface and wrap the original Pageable. (for that number n your class can consult the wrapped interface; read the API for the Pageable interface).

Error while sending mail when using Java Mail API

Hi Experts,
I am trying to execute a webdynpro application which uses the Java Mail API to send emails. The exception that I get on executing the application is :
Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
Can anybody please help me sort out the issue.
Regards
Abdullah

Hi,
Usually one get this error if the SMTP server is configured not to relay mails (a security measure) or the SMTP server need the mail to be sent from a trusted IP or with proper authentication. Some SMTP servers are configured to block junk mails.
Pls check with your mail server administrator.

Java Persistence API and creation of databases

Hi All
I have designed a small address book application which uses a database to store the information. I have used the new Java Persistence API to take care of my transactions and querrys with the database. This works great for one set database which is generated the first time the application runs and is used all the time.
However I would like to make it so that the user can create a new address book (database) with a different name, I am not sure how I would do this using the Java Persistence API. I know the persistence.xml file must be placed in the META-INF directory of the source, so how would I be able manipulate the file or could I place the file somewhere else.
David

I am using the Derby database. I can create a database by passing the create command when I create the entity Manager like so:
Connection c = DriverManager.getConnection("jdbc:derby:AddressBook;create=true", "app", "app");My problem is that as I understand it the persistence.xml file must know the name of the database. Unless there is another way of setting this. The line in the persistence file I am referring to is:
<property name="toplink.jdbc.url" value="jdbc:derby:AddressBook"/>I wonder if I can progamatically set this value so that I have a default database in the persistence.xml and others can then create there own.

Read Attachments using Java Mapping API

Hello,
after investigating the Java Mapping API a little deeper I found some very interesting Interfaces "InputAttachments" and "Attachments" which could do exactly what is required:
Reading attachments and convert them into base64 code.
As I am not an experienced Java Programmer howeve, I am note sure how to use those interfaces.
For example there is a method defined in interface "InputAttachments":
Attachment getAttachment(String contentID)
How do I use it? If I use it in a way like "InputAttachments.getAttachment("abc");" then I get the error that it is not a static method. However how do I instantiate "InputAttachments".? As it is an interface I am not sure how to do this.
Any idea how to handle these methods?

Hi,
I am working on the similar. I am able to attach txt files and csv files but have trouble attaching xcel and pdf's. Any input is appreciated. Thanks

(Java Base API / JNI ) in tomcat

Hi All,
(this is a question I asked on the 'C-API' forum but I got no answer. I hope I'll have more success here )
I'm trying to access a database built with the C-API from a tomcat/glassfish server using the Java native API. (I need to read data produced with the C API)
I put the Environment in the application context so all user will share the same instance of the database.
first question: is it a good idea ? What would be the best practice ? can I safely use this application in a multithreaded environment ?
The problem was that the 'System.loadLibrary' method is called each time my application is re-deployed: so an exception was thrown !! (library already loaded) because the server has already loaded the db library in a previous deployment. To solve the problem I put a silent 'try... catch...' around this System.loadLibrary in the source code of com/sleepycat/db/internal/db_javaJNI.java
2nd question: is there a way to avoid this hack ?
Thank you for any answer
Pierre

The JE team does not know the answer to your question, but will see if we can find redirect it to someone who might know.

Issue with JAVA Mail API

Hi
We have a requirement to create a custom e mail. For the same I am trying to use Java Mail API.I am facing an issue with the following code:
session session1 = session.getInstance(properties, null);
System gives an error Sourced file: inline evaluation of: ``Properties props = new Properties(); session session1 = session.getInstance(prop . . . '' : Typed variable declaration : Class: session not found in namespace
Is there some specific API i need to import for session class. Kindly suggest.
Regards
Shobha

Hi Shobha,
I was also facing the same issue from last couple of weeks and just now i have achieved the working functionality.
