Please I am an Idiot HELP

2006-04-16 20:22

I wrote an applet several months ago to handle the entry of our companies quotes. I am now trying to create reports based on that system. I have created a report using IReport named delivery.jrxml. This report runs fine from IReport but I am having huge trouble loading it from my applet. The applet resides in a jar file located at the base of the website. the .jrxml file is located in the same directory as the jar (I have also tried putting the file in the jar).

Any advice on how to do this would be very helpful.


Let me start by stating what I have tried so far.

I have added a button to my form that when pressed run this code:

InputStream is = new FileInputStream(new File("delivery.jrxml"));

JRXmlLoader jlo = new JRXmlLoader(JRXmlDigesterFactory.createDigester());

JasperDesign jd = jlo.loadXML(is);

and I get this error:

java.io.FileNotFoundException: delivery.jrxml (The system cannot find the path specified)


I have Also tried InputStream is = new FileInputStream(new File("./delivery.jrxml"));


InputStream is = new FileInputStream(new File("/delivery.jrxml"));

Along with others with no avail.


I have looked at the applet examples jasperreports-1.2.1-projectjasperreports-1.2.1demosampleswebappapplets

but I don't understand what

<PARAM NAME = "REPORT_URL" VALUE ="../servlets/jasperprint">

is pointing to I could not find that file.


But I am ranting I have been working on this for 24 hours straight so I am a little deleterious. If none of this make since please let me know and I will clear it up first thing in the morning.


Thanks for any help in advance.

Theoretically, you have to include your file in the applet jar, so it gets downloaded and present within your final user´s applet java environment.


Once there, your applet should be able to access to it by using the following:


InputStream theStream = this.getClass().getResourceAsStream("/myPathIntoTheJar/myReport.jrxml");


Please let me know if this solution works. I have not tested it.

Sorry, I have not experience with setting applets, although it seems like for some reason, your applet is not having the proper access to the JRE libraries in the client side. java.lang.Object belongs to the core of the Java language. I would not be able to be more concrete.
