I'm running into a problem with Jaspersoft Studio. I had a working project with a library defining custom conversion functions. Lately my .jrxml views don't find my functions anymore.
When clicking on preview of *file1.jrxml* in folder *[PROJ_ROOT]/set1*, following error message is thrown:
"The method AUTO_CONVERT(String) is undefined for the type file1_1434540912649_515329"
AUTO_CONVERT is located in *[PROJ_ROOT]/src/de/companyname/packagename/MyClass.java*,
all variables passed to it are of type String.
Sample from MyClass.java:
package de.companyname.packagename;
..
@FunctionCategories({ de.companyname.packagename.MyClass.class })
public class MyClass {
..
@Function("AUTO_CONVERT")
@FunctionParameters({ @FunctionParameter("aString") })
public static String AUTO_CONVERT(String aString) {
...
The jasperreports_messages.properties file is in [PROJ_ROOT]/src with content (also tried moving it to same dir as Myclass):
de.companyname.packagename.MyClass.name = MyClass
de.companyname.packagename.MyClass.description=Custom Functions
de.companyname.packagename.MyClass.AUTO_CONVERT.name = Auto Convert
de.companyname.packagename.MyClass.AUTO_CONVERT.description= Descr
jasperreports_extension.properties, also in [PROJ_ROOT]/src:
net.sf.jasperreports.extension.registry.factory.functions=net.sf.jasperreports.functions.FunctionsRegistryFactory
net.sf.jasperreports.extension.functions.test=test
Previously I managed to fix these kind of problems by modifying the build path settings and simply adding the project root ( which doesn't change anything now ). My functions don't appear in the expression editor.
JasperSoft also seems to have some kind of problem "acknowleding" my src folder. Instead of displaying a folder like src directory in the Project Explorer and *de/companyname/packagename* as subelement, it now displays *src/de/companyname/packagename* as one single element. My classes packagenames are marked red and expect src as a prefix (*src.de.companyname.packagename* instead of *de.companyname.packagename*)
I can trick JasperSoft into "acknowleding" the src folder by chosing New->SourceFolder in the project root, but this gets changed back by some JasperSoft magic after a while.
Moving to de/companyname/packagename and working without src fixes the packagename issues, but still my views don't recognize my custom classes.
My class path looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path=""/>
<classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry exported="true" kind="con" path="net.sf.jasperreports.JR_CONTAINER"/>
<classpathentry exported="true" kind="con" path="com.jaspersoft.server.JRS_CONTAINER"/>
<classpathentry kind="output" path="bin"/>
</classpath>
Anyone have an idea what may be going wrong and how to fix this? I'm pretty sure it must be something with the project setup. Simply creating a new one didn't help either.
Strangely when I chose the FunctionsLibrary wizard and have JSoft create example methods + a sample report, the expected hello world function fails with a JRExpressionEvalException for the Hello World message. If relevant - sloppy example or my mistake?
Thanks
Update:
I fixed the strange src folder behaviour by doing this:
.classpath:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry excluding="src/" kind="src" path=""/>
<classpathentry exported="true" kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry exported="true" kind="con" path="net.sf.jasperreports.JR_CONTAINER"/>
<classpathentry exported="true" kind="con" path="com.jaspersoft.server.JRS_CONTAINER"/>
<classpathentry kind="output" path="bin"/>
</classpath>
