no swt-mozilla-gtk-4332 in java.library.path

问题

(See update at bottom for new information.)

I have a Java SWT application that includes an integrated browser.

Everything works fine on Windows and on CENTOS 6.5. I was asked to get the application to work on a new computer to which I installed CENTOS 7.

I keep receiving the no swt-mozilla-gtk-4332 in java.library.path error message.

I am aware of the various pages that talk on this issue. For instance:

StackOverflow 10165693, 6518568, 7130980

Jazz.net, Eclipse.org

I am using Firefox 24.8.0. That came with CENTOS 7. I just updated all the software too.

The references indicated that I should have OpenJDK, which I do. That is the only version that can execute Java.

I installed per another recommendation xulrunner (yum install xulrunner).

I set: MOZILLA_FIVE_HOME=/usr/lib/mozilla (Some say to use that others say not to. I tried both. Also, one issue said to point to that to "/usr/lib64/xulrunner" less the double quotes, but that did not work. Yes, this folder exists.)

587 people and counting gave thumbs up to the Ubuntu solution of:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

There is no jni folder, and any ways that option did not work.

As I mentioned there is only one a program, so

sudo update-alternatives --config java

was of no use.

What could the problem be and how to solve it? Since the CENTOS 6.5 machine works (maybe because of a missing software package?) and 7 does not, it cannot be just that I need to add something to my jar file, as it worked before.

Note: here is my /etc/profile.d/java.sh file content:

export MOZILLA_FIVE_HOME=/usr/lib/mozilla
export LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH}

Here is the actual error output.

Update

The error text showed the problem, namely that the system could not find libxpcom.so. Mozilla (xulruntime) in version 22.0 replaced the files, libxpcom.so and mozsqlite3.so, with libxul.so. The file, libsmozsqlite3.so stayed for a few more versions than disappeared as well. All other files are the same as version 28.x, which is the current version as of today (2014.09.18).

The integrated SWT browser for some reason wants the older version, even though it is not there. The questions are:

What is the mechanism that SWT determines which version of the Gecko GTK+ / xulrunner to use?
Would a newer version of SWT, although I thought that my version with Eclipse Kepler was current, solve the problem?
How do I get SWT to target the new version?
Is the problem Firefox or Chrome or what related?

I understand most of the problem now, but not all of it.

I see that Eclipse is at Luna now, so that may solve the problem, have to check. That usually means an updated SWT library. I really thought that Java was version independent, but I guess not entirely.

回答1:

i just had this same error on Ubuntu 14.04 and solved it by installing an older version:

sudo apt-get install libwebkitgtk-1.0-0

libwebkitgtk-3.0-0 was already installed

回答2:

For Linux Mint 19 it worked with this (same as marengaz' answer)

sudo apt-get install libwebkitgtk-1.0-0

回答3:

I was on SWT/GTK+ v4.3 and needed to download and update to SWT/GTK+ v4.4 (or the beta of v4.5), which supports the new GTK+ introduced in GTK version v22.* and present in CENTOS 7. See comment from Baz and myself.

回答4:

sudo apt-get install libwebkitgtk-1.0-0

I tested many java versions, think that it was java. But what really makes sense was to install libwebkitgtk for versions 7.1 and 8.0 of pentaho data integration.

回答5:

I tried something like

sudo yum install libwebkitgtk-1.0-0

on fedora 28 and I got this message

" Last metadata expiration check: 0:33:01 ago on Wed 02 Jan 2019 06:38:13 PM -02. No match for argument: libwebkitgtk-1.0-0 Error: Unable to find a match "

As a read in this post

https://community.hitachivantara.com/thread/13998-problems-with-libwebkitgtk-10-0

There is no suport for version 1 of libwebkitgtk on fedora
