Java-FX failed to load resource exception

Question

I am running my Java-FX application via webstart by tomcat server. After signing and versioning of jars I having this problem when am accessing it through web browser. I am using jnlp and version protocol to start the application through tomcat server.

ExitException[ 3]com.sun.deploy.net.FailedDownloadException: Unable to load resource: 
  (httP://127.0.0.1:8080/gyms/lib/commons-collections-3.2.1.jar?version-id=1.0.1, 1.0.1)

This seems to have ***nothing*** to do with Swing! – Andrew Thompson Mar 30 '15 at 05:50 — Andrew Thompson, Mar 30 '15 at 05:50
Uh, it's missing commons-collections apparently? – nablex Mar 30 '15 at 05:59 — nablex, Mar 30 '15 at 05:59

You didn't provide enough information to work with. – Roland Mar 30 '15 at 06:35 — Roland, Mar 30 '15 at 06:35

It seems you are using a jnlp-file with a line like this:

    <jar href="commons-collections-3.2.1.jar" version="1.0.1" />

So you are using the version-based download protocol. This will result in the server looking for a file called commons-collections-3.2.1__V1.0.1.jar which apparently is not there.

Bottom line: do not specify two conflicting version-numbers in your jnlp. Decide wether you want to use versioned download and omit the version-number in the href-attribute or use simple download and omit the version-attribute.

i m using version based protocol, The version i defined is there after signing of jar , wen i trying access this via webstart it is showing Application error. – anuj mathur Mar 30 '15 at 06:43
so you got a file called `commons-collections-3.2.1__V1.0.1.jar`? – piet.t Mar 30 '15 at 06:54
yes in the lib folder and that path is in jnlp file also with version. – anuj mathur Mar 30 '15 at 07:10
have you tried it without versioning to see if it works? – Saeid Nourian Mar 30 '15 at 14:53

Problem is solved because I am using Java 1.7.51 update and also i am usin third api which is not supported in java 8 which is also installed in my desktop. The program(x86) should not have any version of java greater than java 7 as the application is taking java/bin from x86 only. that is why that failed download exception is coming at run time.
