Problems with InstallAnywhere 2.5
Dear folks, I recently downloaded the evaluation version of InstallAnywhere 2.5 from www.zerog.com. It's a nice pure-Java product for building installers. I plan to use it under Linux, with the Blackdown JDK. I could create a simple installer with it and all went fine, except that now I am not able to reopen and edit the project I created with it. I can select the project to open, but when I click on the "Next" button, a small blank window appears and then the program just sits there doing nothing, not even consuming CPU time. The previous version (2.0) did not have this problem. I am running JDK 1.1.7v1a under Redhat Linux 5.2 (Intel), and tried using green as well as native threads. Also tried 1.1.6 with the same result. If you haven't already done it, I suggest that you take a look at this product, which looks very good, even though a bit pricey.

Signed applets
Does anybody have any experience with signing applets? I can't seem to make it work. Here is more detailed information: Environment: Linux RH 5.2 (2.0.36) Blackdown JDK 1.1.7v1a Netscape Communicator 4.5 Problem description: I have written an applet, compiled it and created a jar file. Since the applet needs to read a file on the client system it must be signed. I have followed the steps outlined in http://java.sun.com/security/usingJavakey.html in order to sign the applet. However, when I load the applet in Navigator, the Java Console displays the following: # Error: Invalid Hash of this JAR entry (-7882) # jar file: /tmp/jzip36F28FDB0001BB9 # path: FileSenderApplet$ButtonHandler.class # Error: Strange PKCS7 or RSA failure (-7881) # jar file: /tmp/jzip36F28FDB0001BB9 # path: /tmp/jzip36F28FDB0001BB9 # Error: loading of signatures has failed (-1) # jar file: /tmp/jzip36F28FDB0001BB9 # path: /home/ugo/work/CBIM/prqa/ and of course the applet throws a SecurityException whenever it tries to open a local file. I have seen signed applets work in Navigator, so it must be a problem with my understanding of javakey, but where?

For me it stops while showing the splash screen, throwing an exception that says that it can't find some file that is right there. Oh well, not that I care much, I would rather prefer that Sun make up its mind about releasing the HotJava Browser Bean under the SCSL as it announced many months ago. I regret not having a good pure-Java browser component to add to my apps. I've tried Ice (http://www.icesoft.no) but the current release candidate is still to buggy, beside costing $5k for a source license. Also I would like to know if Sun intend to make a Swing-compatible version of the Browser Bean, since it looks like the current version uses a heavyweight component which we all know is a big no-no when doing a Swing-based application. -- Ugo Cei - [EMAIL PROTECTED] Fuori Orario Srl - Galleria Manzoni 15, 27100 Pavia - Italy Tel: +39.382.22651, Fax: +39.382.539467 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I did it just yesterday, but I downloaded and installed JRE 1.1.6v5 as
suggested by Oracle in its installation instructions. The only problem I
had was with a message form dbassist telling me I had no support for
national languages. I Ignored it and it created the database. Since then
I just had the time to test that the instance is up and running.
This is on a RH 6.0 system with 256MB RAM + 256MB of swap.

This is curious. At first I tried using the IBM JDK and the runInstaller script died complaining that the jre did non support the "-green" option (IBM does not support it indeed). Then I downloaded and installed blackdown's 1.1.6v5 and run it successfully and I am positively certain that I did NOT install the native thread package. Infact, as the installer ran I was watching it using "top" and there was only one java process. > HOWEVER, we are unable to configure Net8.

Don't know what is going on here, but I did not run netasst, I just ran "lsnrctl start" and now have a listener running and listening on port 1521/tcp. I also created a tablespace and a user and used "sqlplus user/password" to create a few tables. But frankly I don't know if this is a symptom that I have Net8 correctly installed and configured. I will try to run netasst later to see how it goes. -- Ugo Cei - [EMAIL PROTECTED] Fuori Orario Srl - Galleria Manzoni 15, 27100 Pavia - Italy Tel: +39.382.22651, Fax: +39.382.539467 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
