dynaTrace WebStart client

Mike

What kind of issue are u seeing? We have seen one instance where the Java Webstart was trying to look for some update from internet and the proxy would stop it. We had to disable proxy to make it work. There is an patch with disables this lookup. 

Thanks

I think this refers to the Tech Alert at Technical Alerts dynaTrace DATM, we are working on a FixPack for this problem but the changed security settings require us to do a larger set of changes which requires proper testing, so I cannot give an defined date yet, stay tuned for an update...

Hi Rajesh,

first, I would be interested if your Web Start Client starts without any issues. If so, I would assume that you run a Java version lower than Java 7 update 45.  In that case you are not affected of the Web Start Client Issue listed at Technical Alerts dynaTrace DATM.

Thanks Anita/Dominik for the replies.

The problem stems from the technical alert. Once notified that there was a problem with java 7 update 45 the message went out to the customer base via me emailing them. Unfortunately not everyone reads emails or is subscribed to this watch list, or for that matter has an account on the community portal. There are over 300 users of dynaTrace at this customer. Then inevitably some users automatically runs the Java 7 update 45 (which it prompts you to do) and then the dynaTrace web start client does not work. That was the reason for this post to understand when a fix will be available for dynaTrace web start client that supports java 7 update 45.

Thanks

Mike

Hi all,

As Oracle is very good at hiding archived downloads, I thought I'd share the link to Java 7 update 40 here:

• Main download page (all OS's): http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jre-7u40-oth-JPR
• Direct link to 32-bit offline plugin installer: http://download.oracle.com/otn/java/jdk/7u40-b43/jre-7u40-windows-i586.exe

Note that you need to create an account to access these downloads.

Regards,

The WebStart issue has also been reported with a 1.6 JVM - 1.6.0_65.

This is a non-public 1.6 JVM that can be obtained if you have purchased Java support from Oracle. It is not widely used currently. The existing fix also works for 1.6.0_65.

The JRE 1.6u45 on Windows XP is still reporting a missing signature in the jnlp file. Is there a possible solution to fix this problem?

Our customers, can not upgrade or downgrade their installed JRE.

FYI, we also verified that the latest Java Update 1.7.0_51 behaves the same way as Java 1.7.0_45 and no new hurdles were put in by Oracle. After installing the FixPack in dynaTrace 5.5 or upgrading to dynaTrace 5.6, Webstart Client should work fine!

I have upgraded the Java version to 1.7.0_51 and if I use Java Web start I still the error same error

Does the 5.6 client work with Java 1.7_51?  It sounds like things are still broken.  Our security deparatment will be pushing Java 1.7_51 very soon. I need to know if the webstart client works with this release.

Please advise.

Thanks,

Jim
