Scriptlet path.

2004-11-29 18:53

Hi. Is it possible to indicate the path to a scriptlet class? I placed it right where the compiled xml (the jasper file) is in a web app, but it can't load it... I have to place the class somewhere in the claspath, which makes sence but i would rather have the scriptlet together with the report. Any clues?

yes, the scriplet class must be in the classpath,

and in the xml template, the full qualified scriplet class:

scriptletClass="com.lectra.common.reporting.engine.data.Scriptlet"

So i guess i need to write a classloader if the scriptlets are outside of the classpath in my servlet container...

 

Thanks!

Maybe this is too obvious, but just drop the compiled scriplet into the WEB-INF/classes directory and all should be well.

I wanted to avoid that since i was allowing users to upload reports, i wanted to place the scriptlets and subreports in the same folder where i'm storing the uploaded reports.

 

Right now i'm toying with the idea of keeping all the stuff in database. I don't have time for implementing it right now, but i may give it a try soon....

maybe somebody will read this..

this means that you must also store images in db you use in your report, i dont know if this is a good idea. i wrote this already with storing reports as blob in db, but it seems to be a bit difficult with images/scriptlets etc. So i put it in a directory where my tomcat/jboss is running. now i have the same problem like you, i cant use scriptlets because the classpath dont work.

 

i tried this but it only works the first time i call the servlet:

 

private void setScriptletLoader(){

try {

URLClassLoader parentLoader = null, scriptletLoader = null;

 

Object currentloader = Thread.currentThread().getContextClassLoader();

if (currentloader instanceof URLClassLoader) parentLoader = (URLClassLoader)currentloader;

scriptletLoader = new URLClassLoader(new URL[]{ new URL(new File(homeDir + System.getProperty("file.separator")).toURL().toString())}, parentLoader);

Thread.currentThread().setContextClassLoader(scriptletLoader);

} catch (IOException e) {

e.printStackTrace();

}

}

 

 

a second time i call the servlet, i get a classnotfoundexception for the scriptlet.
