 Posted: Tue Oct 14, 2008 4:11 pm Post subject: [SOLVED] solution for JAVA support in Opera on PPC, please? |
 |
|
Hello there!
As reported many times, Opera (9.60 in my case) tends to simply crash with a huge memory dump (>300MB!) with the latest ibm-jdk or imb-jre as JVMs.
Some users reported that ibm-jdk-1.4.2.x seems to work with Opera, but...
1)IBM has ibm-jdk-1.4.2.12 in theit download page (this package needs manual fetching...go figure)
2)There's no ebuild for 1.4.2.12 in the actual portage three!! Synced days ago.
AND
1)There is ebuild for 1.4.11 in the portage three
2)There is NO 1.4.11 download in the IBM page! (1.4.12 pseries, only)
HOW am I supposed to use JAVA JVM with OPERA now? It looks like a dead end. Every version I tried (1.5, 1.6, etc...) just CRASH Opera...
And Firefox is not an option on this light system of mine 
I am on Opera 9.60, and gentoo-sources 2.26-r1 as kernel.
If it wasn't enough, this is what I get trying to emerge the blackdown jre:
>>> Emerging (1 of 1) dev-java/blackdown-jre-1.4.2.03-r14 to /
* checking ebuild checksums  ... [ ok ]
* checking auxfile checksums ... [ ok ]

>>> Unpacking source...

* ERROR: dev-java/blackdown-jre-1.4.2.03-r14 failed.
* Call stack:

* environment, line 2606: Called die
* The specific snippet of code:
* die "Failed to get offset of tarball!";
* The die message:
* Failed to get offset of tarball!
*
* If you need support, post the topmost build error, and the call stack if relevant.
* A complete build log is located at '/var/tmp/portage/dev-java/blackdown-jre-1.4.2.03-r14/temp/build.log'.
* The ebuild environment file is located at '/var/tmp/portage/dev-java/blackdown-jre-1.4.2.03-r14/temp/environment'.
*
Thanks!

1.4.2.12 was marked stable today. Please sync and try again. |

Still NOT working...
Tried ibm-jdk-1.42.11, ibm-jre-1.42.11, ibm-jdk-1.42.12 and ibm-jre-1.42.12. No problems emerging them after downloading the corresponding tgzs, etc.. but OPERA 9.60 keeps crashing on JAVA tests and any java applet.
Have you JAVA working in OPERA on PowerPC? Or any other browser not being the heavy Firefox 2.x-3-x??
Thanks |

No, it seems nobody is very interested with Java and Opera though, sorry. The PowerPC team has historically never been very active with Java related topics.

OK, Jose... I'm developing with Java on Linux so I need a Java-capable browser: can you give me any ideas, please?
I am starting to consider Firefox, but before I face several compilation hours in my (nice) G4, I'd like to know if that browser allows java on powerpc.
Thanks! |

Just emerge mozilla-firefox with the java USE flag enabled and you should be fine. |

Between one hour and a half and two hours. It shouldn't take longer than that. |

Allright, I have an update on this issue and a fix/workaround.
Opera crashes with the following error:

It seems to me that Opera can't find the real Java path. Check the path in the error log:
/opt/ibm-jdk-bin-1.6.0.2/jre/lib/lib/jars.cfg
The real path should be:
/opt/ibm-jdk-bin-1.6.0.2/jre/lib/jars.cfg
It seems to me that Opera is trying to find the file in "$JAVA_PATH_PROVIDED_BY_THE_USER/../lib". Since my Java path contains the "ppc" at the end, it doesn't work and duplicates "lib".
If I create a symlink "lib" in "/opt/ibm-jdk-bin-1.6.0.2/jre/lib", Java applets work fine in Opera because the path "/opt/ibm-jdk-bin-1.6.0.2/jre/lib/lib/" is now valid.
None the less, Opera should not crash when the Java path is not valid. I submitted a bug report to the Opera guys. |

| This seems to be fixed in Opera 9.62, now in Portage. Can anyone confirm this? |

It does NOT work here: with opera 9.62, after pointing Opera to /opt/ibm-jdk-bin-1.6.0.2/jre/lib/ppc/ , opera still CRASHES miserably on any page containing java applets.
Emerging firefox with the USE="java" flag did NOT work, either: it emerges ibm-jdk-bin-1.6.0.2 along with Firefox, but it doesn't create the symlink in /usr/lib/mozilla/plugins, so I went and did:
ln -s /opt/ibm-jdk-bin-1.6.0.2/jre/plugin/ppc/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins/
ln -s /opt/ibm-jdk-bin-1.6.0.2/jre/plugin/ppc/ns7/libjavaplugin_oji.so /usr/lib/mozilla-firefox/plugins/
NOW Firefox supports java applets! WELL, SOLVED (partially) since Opera wob't work but firefox does!! |

Have you tried the solution I posted here?

NOW Firefox supports java applets! |
My /usr/lib/mozilla/plugins is empty too and I have Java support in Firefox. I believe the correct folder is /usr/lib/nsbrowser/plugins. Please check if you have that. |
