JNLP should use a specific Java version but error results

Question

I'm facing a problem here. I want to use a special version to run our java webstart application but just for one jnlp. ("It was tested, ... blabla we can't use a new version... blabla" by random windbag)

So I tried to configure our JNLP like this:

<resources>
    <j2se version="1.6.0_29" href="http://java.oracle.com/products/autodl/j2se"/>
    ...
</resources>

When I start this jnlp now I get following Error even if the right Java is installed:

Error: The application has requested a version of the JRE (version 1.6.0_29) that currently is not locally installed. Java Web Start is unable to automatically download and install the requested version. This JRE must be installed manually.

Update

In the JNLP File Syntax it's allowed to use a specific Java version like 1.6.0_29. I even tried it with 1.6.0_29-b11 - still the same error.

Exact product versions (implementation versions) may also be specified. by including the href attribute. For example, 1.3.1_07, 1.4.2, or 1.5.0-beta2 by Sun Microsystems, Inc. For example,

<j2se version="1.4.2" href="http://java.sun.com/products/autodl/j2se"/>

or

<j2se version="1.4.2_04" href="http://java.sun.com/products/autodl/j2se"/>

Edit

The given answer is not helping and not the right answer.

Answer 1

This is quite common. Make sure that each client machine has enabled 1.6.0_29 for JNLP/Webstart.

Installing 1.6.0_29 is not necessarily enough to tell webstart that it's available. See this post for more information

Answer 2

I had installed Java 1.6.0_21 and it was enabled at the Java Control Panel. However I got the same error message that it's stated in the question: "The application has requested a version of the JRE (version 1.6.0_29) that currently is not locally installed"

I got this message even if I tried with different lines in the JNLP, such as:

<j2se version="1.6.0_29"/>

or

<j2se version="1.6.0_29-b06"/>

I solved this by editing the JNLP file with the following line:

<j2se version="1.6"/>

So the documentation line "Exact product versions (implementation versions) may also be specified" seems to be false.

Answer 3

Do you use :

jnlp spec="1.0+"

If so you should try with :

jnlp spec="6.0+"

I found this link, maybe there is something wrong in the configuration of your browser/JRE, or are you under a proxy?
