err class(scriptlet) not found in namespace?

2004-10-01 09:16

Class: AccLib not found in namespace.

I created a scriptlet also create a jar file of that class too.

then call

((AccLib)$P{REPORT_SCRIPTLET}).hello() in my xml.

when I compile it I get the error

"AccLib not found in namespace."

Any suggestion?

I am so new in scriptlet and jasper.

 

Thanks,

the jar needs to be on the classpath and the class name should be fully qualified (com.xyz.AccLib)

Thanks,

But the class is like you said(white.Id.AccLib)

and I created a jar file and and it's in the classpath,

AI compilked is okay,when i run it I get error:

"Error loading scriptlet class : AccLib"

nested by

ClassNotFoundException: AccLib

 

What else should i check?

Can you cjeck the java file and theat part of the xml file please?

/**

* File: AccLib.java

* Created on Oct 1, 2004

* Description: TODO

*/

package xxx.yyy;

import dori.jasper.engine.*;

 

 

public class AccLib extends JRDefaultScriptlet{

 

public void beforeGroupInit(String s){}

public void beforePageInit(){}

public void beforeColumnInit(){}

public void afterColumnInit(){}

public void afterGroupInit(String s){}

public void beforeReportInit(){}

public void afterReportInit(){}

public void beforeDetailEval(){}

public void afterDetailEval(){}

public void afterPageInit(){}

 

public String hello() throws JRScriptletException

{

return "I'm the report's scriptlet object.";

}

 

 

}

 

then in xml put :

scriptletClass="AccLib"

<textFieldExpression class="java.lang.String">((AccLib)$P{REPORT_SCRIPTLET}).hello()</textFieldExpression>

What I meant was that where ever you use you class, it needs to be fully qualified.

 

When you typecast the REPORT_SCRIPTLET in the <jasperReport> tag where you identify it...everywhere.

 

((xxx.yyy.AccLib)$P{REPORT_SCRIPTLET}).hello()

I added

scriptletClass="xxx.yyy.AccLib" in <jasperReort>

and also

((xxx.yyy.AccLib)$P{REPORT_SCRIPTLET}).hello()

 

Now I get

java.lang.ClassNotFoundException: xxx.yyy.AccLib

nested BY :

dori.jasper.engine.JRException: Error loading scriptlet class : xxx.yyy.AccLib

 

what else should i change to make it work?

Even if I remove the calling hello() method,and just put the complete name of the class in the <jasperReport>

I get same error that couldn't find the class,But I

think I add the jar file to the shared_library in my

project and also lib directory under web-inf.

and defined in the project classpath.

where else should I add.

I think it needs to be in the same place as your jasperreports.jar.

 

But, it definitely sounds like a classpath error.
