When I package my stand-alone-java-application, that compiles, renders and prints Jasper-Reports, in a fat jar with all dependencies, I get the error that the function TEXT – a function used in the report and defined in the net.sf.jasperreports-functions-library is not found.
The method TEXT(Integer, String) is undefined for the type [...]
value = IF(LEN(TEXT(((java.lang.Integer)parameter_X.getValue()),"#"))==2,"***",REPT("*",6-LEN(TEXT(((java.lang.Integer)parameter_X.getValue()),"#")))) //$JR_EXPR_ID=58$
Other functions from the same library work. When I run the application with gradle run, the function is found and the report can be printed. The library is on my classpath.
There are several similar questions on this site and Stackoverflow, but neither provided answers, that worked for me. In the following, I will explain what I tried:
In my build.gradle-File I defined dependencies to the following libraries:
implementation('net.sf.jasperreports:jasperreports:6.18.1')
implementation('net.sf.jasperreports:jasperreports-functions:6.18.1')
In my java-Files, I created a DesignFile and statically imported the functions into it. I tried two methods:
Method 1 as given in an answer in this thread: Unresolved symbols when compiling jasper report
/*…*/
designFile = JRXmlLoader.load(sourceFile.getAbsolutePath());
designFile.addImport("static net.sf.jasperreports.functions.standard.TextFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.MathFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.DateTimeFunctions.*");
designFile.addImport("static net.sf.jasperreports.functions.standard.LogicalFunctions.*");
JasperReport compiledReport = JasperCompileManager.getInstance(ctx).compile(designFile);
/*…*/
Method 2: importing each function on its own
public static String[] textFunctions(){
return new String[]{"BASE", "CHAR", "CLEAN", "CODE", "CONCATENATE", "DOUBLE_VALUE",
"EXACT", "FIND", /*"FIXED", */"FLOAT_VALUE", "INTEGER_VALUE", "LEFT", "LEN", "LONG_VALUE",
"LOWER", "LTRIM", "MID", "PROPER", "REPLACE", "REPT", "RIGHT", "RTRIM", "SEARCH", "SUBSTITUTE",
"T", /*"TEXT",*/ "TRIM", "UPPER"};
}}
/*…*/
designFile = JRXmlLoader.load(sourceFile.getAbsolutePath());
for (String textFunction : textFunctions()){
designFile.addImport("static net.sf.jasperreports.functions.standard.TextFunctions." + textFunction);
}/* similarly for logical functions, numeric functions and datetime functions*/
}
JasperReport compiledReport = JasperCompileManager.getInstance(ctx).compile(designFile);
/*…*/
As you can see, the function TEXT is commented out. That’s because the program fails at runtime when run with “gradle run”, when I comment it in:
net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:
1. The import net.sf.jasperreports.functions.standard.TextFunctions.TEXT cannot be resolved
import static net.sf.jasperreports.functions.standard.TextFunctions.TEXT;
The same thing is true with most datetime-functions, in fact, only TIME can be imported to the DesignObject without error at runtime
In addition to that, when I type net.sf.jasperreports.functions.standard.TextFunctions. in my IDE, the content-assist shows a list of available functions, yet TEXT is missing.
I suspected, that the function is simply missing in the library, but it is there. In the .gradle/cache/modules-2/files-2.1/… directory, there is the jar with the TextFunctions.java, that contains the function TEXT:
When building the FatJar with dependencies, I have a TextFunctions.class-File in it, that contains the TEXT-Function as well.
In my jar, there are two jasperreports_extension.properties on the root level:
with the smaller one (from the jasperreport-functions-dependency) containing the following lines:
net.sf.jasperreports.extension.registry.factory.functions=net.sf.jasperreports.functions.FunctionsRegistryFactory
net.sf.jasperreports.extension.functions.datetime=net.sf.jasperreports.functions.standard.DateTimeFunctions
net.sf.jasperreports.extension.functions.math=net.sf.jasperreports.functions.standard.MathFunctions, net.sf.jasperreports.functions.standard.LogicalFunctions
net.sf.jasperreports.extension.functions.text=net.sf.jasperreports.functions.standard.TextFunctions
net.sf.jasperreports.extension.functions.report=net.sf.jasperreports.functions.standard.ReportFunctions
Funnily enough, commenting out TEXT, running it locally with gradle run, it works without problems. But packaging it and running it with java -jar it fails to find this function. And statically importing this function leads to gradle run failing as well.
What is happening and how can I fix this? I want to distribute my FatJar on a server and run it, but this problems makes it impossible for me.
I am moving my code from JDK 8 to Open JDK 12. While doing so, I am facing following issue :
java.lang.NoSuchFieldException: scl
while trying to call ClassLoader.class.getDeclaredField("scl"). This was working fine in Java 8 but no longer works in newer Java versions.
I did some findings and believe it has got to do with the way working of reflection and use of internal Java packages have changed since Java 8.
Set<URL> classLoaderUrls = computeClassLoaderUrls();
ClassLoader bootstrapClassLoader = ClassLoader.getSystemClassLoader().getParent();
this.classLoader = new URLClassLoader(classLoaderUrls.toArray(new URL[classLoaderUrls.size()]), bootstrapClassLoader);
Field systemClassLoaderField = ClassLoader.class.getDeclaredField("scl");
systemClassLoaderField.setAccessible(true);
this.initialSystemClassLoader = (ClassLoader) systemClassLoaderField.get(null);
systemClassLoaderField.set(null, this.classLoader);
I want to know , if the way to access these classloader and its fields has changed or should I use some other field instead of scl. Thanks
I've updated my intellij to 2017.2.5 and imported all the projects. For some reason, declaration and constructors show some error with Strings. e.g. private String type = "abc"; and name = " xyz"; Error asks me to change it to java.lang.string as a solution.
Jdk is up to date. libraries are up to date, so what is the problem? Project structure looks ok. How do I fix this?
Just delete the line:
import org.apache.xpath.operations.String
This is causing a type conflict between java.lang.String (what you want) and an Apache class (which you probably don't want).
I am using Eclipse Juno and Java.
I was trying to create a new list:
List myList = new ArrayList();
This had an error and the resolution on it was along the lines of change compiler to 1.7 which I accepted. The errror on this list creation line was corrected however I now have many errors thoughout the whole project on lines that were previously working. Some examples are:
class GetAccountAndCubsHandler<T> implements AsyncCallback<List<AccountAndCubs>>
Multiple markers at this line
- The hierarchy of the type GetAccountAndCubsHandler is inconsistent
- List cannot he resolved to a type
public class AccountCreationView extends Composite {
Multiple markers at this line
- The hierarchy of the type AccountCreationView is inconsistent
- Breakpoint:AccountCreationView
#SuppressWarnings("unused")
private String accountId;
First line - Multiple markers at this line
- SuppressWarnings cannot be resolved to a type
- The attribute valie is undefined for the annotation type SuppressWarnings
Second line - String cannot be resolved to a type
As you can imagine having my whole project adversely affected in this way is very disconcerting so any advice on how to recover would be greatly appreciated.

"String cannot be resolved to a type"
Ensure that a valid JRE or JDK is specified in your build-path.
Since you're using Eclipse, right-click on your project, then Properties → Java Build Path.
Perhaps you don't have a Java 7 JRE configured in the Installed JREs preference panel.
I have a problem while transforming the xslt to pdf in java, i am following the same process posted in this link

Please let me know what could be the problem.
As described in the documentation
Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.
Here's how this can happen. Imagine you built some code that used a library with a method called foo(). You compiled your project and then later decided to upgrade the library. You do this by overwriting the old jar file with the new one. You don't recompile your code.
But what you didn't know is the new library removed the foo() method. Now if you run your code, it will throw this exception because your compile code calls this method and it's no longer there.
In your specific case, this isn't necessarily your code with the problem. It could be that you have one library that uses another library and the problem is there (for example, Library X uses version 2 of Library Y, but you only have Library Y version 1 in your classpath). If this is happening, you need to make sure the libraries are using the version they expect.
For your specific problem, you need to find the version of the jar that has org.apache.xmlgraphics.java2d.GraphicContext in it and it needs to have a constructor that takes a... list of org/apache/xmlgraphics/java2d/GraphicContext... maybe. I forget what (L...;)V means.
