Jasper without JDK(P0)

[suppala]

Dear,

Can you please confirm can we use jasper reports without JDK. We are getting below error while opening the report when we remove the JDK.

com.jaspersoft.jasperserver.api.JSExceptionWrapper: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=0$ <--------------> 2. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=1$ <--------------> 3. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=0$ <--------------> 4. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=1$ <--------------> 5. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=0$ <--------------> 6. java.util.Arrays cannot be resolved to a type value = java.util.Arrays.asList(new java.lang.String[] {}); //$JR_EXPR_ID=1$ <--------------> 6 errors at net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:204) at

I'm using Jasper reports with version: 4.7.0

To answer you question, JasperReports jar is a Java library. You need Java to use JasperReports jar.

However, you're using JasperReports Server and you're just getting an error because you're not using it correctly - the error has nothing to do with missing JDK.

Just to confrim from the looks of the question and the error it looks like you are using the JasperReports Library.

If you check the documentation you will see (page 2) that the JR library Requires a JDK for report compilation, which based on your error is what you are trying to do. On page 11 of the same manual you will see the different compilers available depending on the java compiler available (JDK,JDT,Jikes, etc.) 

Unless your reports are dynamically generated there is no need for the App to compile the reports, you can have your reports already compiled (as .jasper files instead of .jrxml). If you do not use report compilation the library does not need to use a JDK.

Look in the document linked above in Page 33 "API Overview" the report lifecycle chart.
