I have written a code in java that help me to generate a pdf . I have used Itext libraries to generate it. This code also consists of database connectivity with postgres. I have used two jar files itextpdf-5.4.5.jar and postgresql-9.0-901.jar. But as i have mentioned that this code is in java. Now i want this code to work as service in my grails project. As i have read some documentaion of grails that grails service do not contain any database connectivity code.So kindly help me though i 'm new to grails. I don't need any plugins of grails.

You can put your existing java file to src/java in Grails Application and create a new service in service directory and call your method like :
FrameworkPDF.createPdf(FILE,FrameworkPDF.getFrameworkData(FRAMEWORK_ID),FRAMEWORK_ID,3);
from any method of service. And also add the jar dependency to your BuildConfig.groovy file like :
compile :"postgresql:postgresql:9.1-901.jdbc3"
compile :"com.itextpdf:itext-pdfa:5.4.5"
It should work.
If you want to use Grails DataSource then you can follow following step:
Remove the PostgresqlConnection class and you can enter your database connection details in DataSource.groovy. Once you have done with that, do following :
in your service and can code like below :
def dataSource
def sql = Sql.newInstance(dataSource)
def row = sql.firstRow("select fname, lname, email from person where id = ${personId}")
if (row) {
return [firstName: row.fname, lastName: row.lname, email: row.email]
}
I hope it should resolve you problem.
If you want to actually treat your java class as a bean (service), you could wire it up as such in the resources.groovy file.
beans = {
frameworkPdfService(your.package.FrameworkPDF){}
}
and then inject it into another service or controller in your app
public class MyService {
def frameworkPdfService
...
}

This is my java code. Before, it calls BatchGenerateResult sequentially which is a lengthy process, but I want to try some multithreading and have each one of them run at the same time. However when I test it, the new time is the same as the old time. I expected the new time to be faster. Does anyone know whats wrong?

}
}
It looks like, for all practical purposes the following code should be the only one which can improve performance by using multithreading.
BufferedImage warpedimage = Exporter.GenerateWarpedLogo(logoPath, maskPath,
mapping, metadata.getInt("width"), metadata.getInt("height"));
// ImageIO.write(warpedimage, "png", new FileOutputStream(classDir +
// "warpedlogo.png"));
Exporter.StampLogo(templatePath, resultPath, x, y, w, h, warpedimage,
filterobj);
The rest of it major IO - I doubt how much performance improvement you can achieve there.
Do a profile and check how long each one of the methods is executing. Depending on that you should be able to understand.
Hi sorry not able add to comment part as just joined..
would suggest to first go for dummy method any check whether it works at your end then add your business logic...
if the sample works then you might need to check your "template" class
here's the sample.. check the timestamp
package example;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class ExecutorStaticExample {
public static void main(String[] args){
ExecutorService ex = Executors.newCachedThreadPool();
for (int i=0;i<10;i++){
ex.execute(new Runnable(){
#Override
public void run() {
helloStatic();
System.out.println(System.currentTimeMillis());
}
});
}
}
static void helloStatic(){
System.out.println("hello form static");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

I'm looking for a solution to create reports using JasperReports for my application. I found some examples but still could not make it work. I'm using Vaadin7
I'm trying this
public class Report {
public Report(){
createShowReport();
}
private void createShowReport(){
final Map map = new HashMap();
StreamResource.StreamSource source = new StreamResource.StreamSource() {
public InputStream getStream() {
byte[] b = null;
try {
b = JasperRunManager.runReportToPdf(getClass().getClassLoader().getResourceAsStream("br/ind/ibg/reports/report3.jasper"), map, new JREmptyDataSource());
} catch (JRException ex) {
ex.printStackTrace();
}
return new ByteArrayInputStream(b);
}
};
StreamResource resource = new StreamResource(source, "report3.pdf");
resource.setMIMEType("application/pdf");
VerticalLayout v = new VerticalLayout();
Embedded e = new Embedded("", resource);
e.setSizeFull();
e.setType(Embedded.TYPE_BROWSER);
v.addComponent(e);
Window w = getWindow();
w.setContent(v);
UI.getCurrent().addWindow(w);
}
private Window getWindow(){
Window w = new Window();
w.setSizeFull();
w.center();
return w;
}
}
Any idea ?
Problem seems to be on the JasperPrint printer = JasperFillManager.fillReport(file, parametros,dados); line.
Make sure that your report is found (file is not null).
In order to show the report, what I usually do is put the resulted pdf in a stream, then create a streamResource with mimeType='application\pdf' and use window.open(resource) to show it.
Example:
StreamResource.StreamSource source = new StreamResource.StreamSource() {
public InputStream getStream() {
byte[] b = null;
try {
b = JasperRunManager.runReportToPdf(getClass().getClassLoader().getResourceAsStream("reports/report3.jasper"), map, con);
} catch (JRException ex) {
ex.printStackTrace();
}
return new ByteArrayInputStream(b);
}
};
StreamResource resource = new StreamResource(source, "report3.pdf", getApplication());
resource.setMIMEType("application/pdf");
getApplication().getMainWindow().open(resource, "_new");
I want to test MessageProcessor1.listAllKeyword method, which in turn
calls HbaseUtil1.getAllKeyword method. Initialy, I had to deal with a problem associated with the static initializer and the constructor. The problem was to initialize a HBASE DB connection. I used powerMock to suppress static and constructor calls and it worked fine.
Even though I mocked HbaseUtil1.getAllKeyword method, actual method is being called and executes all HBase code leading to an exception, in which HBASE server is not up.
EasyMock.expect(hbaseUtil.getAllKeyword("msg", "u1")).andReturn(expectedList);
Please give me any idea on how to avoid an actual method call. I tried many ways but none of them worked.

e.printStackTrace();
}
}
}
The HbaseUtil1 is instantiated within the listAllKeyword method
public String listAllKeyword(String userId) throws IOException {
HbaseUtil1 util = new HbaseUtil1();
...
So the mock one you create in your test isn't being used at all.
If possible, make the HbaseUtil1 object passable, or settable on the MessageProcessor1 class and then set it in the test class.
Also, and note I'm not 100% familiar with PowerMock, you could include HbaseUtil1 in the prepare for test annotation. I think that will make PowerMock instantiate mocks instead of real objects and then use the expectations you provide in you test.

controller.start(MyCrawler.class, 20);
controller.setPolitenessDelay(200);
controller.setMaximumCrawlDepth(2);
}
}
Any suggestions will be appreciated..
How about adding a property to tell which urls you want to exclude.
Add to your exclusions list all the pages that you don't want them to get crawled.
Here is an example:
public class MyCrawler extends WebCrawler {
List<Pattern> exclusionsPatterns;
public MyCrawler() {
exclusionsPatterns = new ArrayList<Pattern>();
//Add here all your exclusions using Regular Expresssions
exclusionsPatterns.add(Pattern.compile("http://investor\\.somehost\\.com.*"));
}
/*
* You should implement this function to specify
* whether the given URL should be visited or not.
*/
public boolean shouldVisit(WebURL url) {
String href = url.getURL().toLowerCase();
//Iterate the patterns to find if the url is excluded.
for (Pattern exclusionPattern : exclusionsPatterns) {
Matcher matcher = exclusionPattern.matcher(href);
if (matcher.matches()) {
return false;
}
}
if (href.startsWith("http://www.ics.uci.edu/")) {
return true;
}
return false;
}
}
In this example we are telling that all urls that start with http://investor.somehost.com should not be crawled.
So these wont be crawled:
http://investor.somehost.com/index.html
http://investor.somehost.com/something/else
I recommend you reading about regular expresions.
I am trying to learn something about JAVA and the best way to do this is creating something I would actually use and know what the purpose of it is.
I am trying to communicate with HyperV (WMI Library).
For example I found the following, my question is: how to use it? I am using Netbeans to create the GUI.
http://www.paulneve.com/wlab/javadoc/org/paulneve/wlab/virtualisation/VirtualisationAccessHyperVImpl.html
Also, how to load jInterop into my project so I can use it?
Thank you.
You can use JInterop for managing all operations of HyperV.
Download JInterop from here.
Add all JInterop jar files to your project build path.
