javatomcattomcat7jasperserver
Failed starting jasperserver: org.springframework.beans.factory.BeanCreationException
I'm trying to start for the very first time Jasperserver and as you probably thinking at this point it didn't end up very well.
What I've done:
- Install Tomcat v7.0.32
- Install Jasperreport v7.1.0
Note:
- When i was installing jasperreport server i've choose to use an external source. I've linked that to the tomcat.
- During jasperreport installation i've also installed postgreSQL.
- When i was installing the tomcat i've choose to use a different port 8000 -> 9000.
- I'm using Windows 10
What I'm doing:
- Staring the tomcat manager (as administrator).
- Opening in a browser localhost:9000/manager/html
The Error:
- If i try to access to localhost:9000/jasperserver:
- So I've checked the log file and there is an error in more than one file:

Conclusion:
I've really no idea what to do! I've tryed to google it but everything is old and not relevant for the error i got. Hopefully you can help me!

Solution
It seems that even though you have JRE 1.7 installed to which Tomcat is pointing to, your system has JRE 1.8 which is actually running. Also, you do not have JDK installed. It is needed to compile Java classes.
Try the following:
Download JDK 1.8 for Windows from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html. You have to accept the license agreement first.
Run the installer. There should not be many options for you to configure, except the install path. Remember this path for later use
When the installer has finished, search for "environment variables". When there, look for
PATHvariable andCLASSPATH. If they are not there, you can create them by adding a new variable.Edit
PATHvariable, add ";path\in\step\2\bin\". In case you do not remember, it is usuallyC:\Program Files\Java\jdk1.8.0_131\bin\. ThePATHvariable gives the location of executables like javac, java etc...Create
JAVA_HOMEvariable and set it to "path/to/jdk". It should be likeC:\Program Files\Java\jdk1.6.0_25Create
JRE_HOMEvariable and set it to "path/to/jre". It should look likeJRE_HOME=C:\Program Files\Java\jdk1.6.0_32\jreCreate
CATALINA_HOMEvariable and set it to the path of the directory into which you have installed Tomcat 4.1. It should lookC:\Program Files\Apache\tomcat\bin\startupCreate
CLASSPATHvariable and set it to "path\common\lib\servlet-api.jar". It should look something likeC:\apache-tomcat-6.0.14\lib\servlet-api.jar.Check if these have been set properly by echoing them on cmd. Simply type
%PATH%,%JAVA_HOME%,%JRE_HOME%etc. into cmd. They should produce the same values as that set in earlier steps.Finally, check if Java has been installed correctly by typing in
javacand hitting enter on cmd. If you get an output like "Usage: javac ....", then it has been installed correctly.Run your project.
PATH is an environment variable used by the operating system (Windows, Mac OS X, Linux) where it will look for native executable programs to run. JAVA_HOME,JRE_HOME are not used by Java itself. Apache Tomcat expects one of these environment variables to be set to the installation directory of the JDK or JRE. CLASSPATH is used by 3rd party apps like tomcat to inject whatever is set in CLASSPATH to every java application you make.CATALINA_HOME points to the installation of tomcat, which may be needed at startup.
.
