Jar file corrupt error in JNLP
Hello there,
I am developing a java swing application which i wanted to make it available on our corporate network for demo purpose.
The java application uses oracle 10g database which i made it to run with web start i.e converted to jnlp.now the jnlp works fine on my computer i mean using
<jnlp spec="1.0+" codebase="file:///C:/Project/jnlp/">
but when i try to run it from my apache server
<jnlp spec="1.0+" codebase="http://192.168.205.81" href="testJdbc.jnlp">
,i get jar corrupt error.i also tried to open the jar file from my apache webroot.but i get the same error.but when i tested a simple jnlp application from apache it works fine.but the difference between the two test is the simple jnlp has only jar fine which is the application.the other apllication has two jar files one for the application and another for oracle jdbc driver.please help. one thing to mention is
when i clcik on the jnlp file in the browser,i get to see the java web start which shows the progress bar and mentioning downloading ojdbc14.jar which starts loading,then it says reading ojdbc14.jar which goes to 100 % and then it displays a box requested http://123.122.22.11/ojdbc14.jar and error saying corrupted ojdbc14.jar(which is the name of the jdbc jar file) .
please help i have been stuck on this for the past one week.

Hi! Maybe the jar file is really corrupted. Try deleting that jar and creating a new one. You can also check if the jar is corrupted by trying to open it with a zip program like winzip.
i can open the jar file with winzip.but cannot open the jar file from the browser.please help.i have reached a dead end with this problem.

Can you try these..1. Try opening the webpage in Firefox instead of IE. 2. Check your jnlp file. By chance you might have specified a wrong file instead of the actual file.If you don't mind can you show the contents of the jnlp file itself?

Try1. Clearing the webstart cache http://www.elluminate.com/support/faqs/jws_clear_cache.jsp2. Look at the last entry in this link. I am sure that might be the problem. Hope this helps. http://discussion.forum.nokia.com/forum/archive/index.php/t-37603.html

<Directory "C:/Project/jnlp">
Options Indexes FollowSymLinks
AllowOverride All
Order allow,deny
