My Pivotal tc Server not Start

Until a few days ago, my STS worked perfectly, but of a sudden, the Pivotal server does not start, throws me the following error message when you run an application:
SEVERE: Class loader creation threw exception
java.io.IOException: The filename, directory name, or volume label syntax is incorrect

They could help me with this problem?
From already, thank you very much for your attention and time.

I had the same error on Tomcat 6 (Pivotal 3.0, STS) and my problem was in catalina.properties. The "common.loader" property was incorrectly using Tomcat 8 style and it was as follows:
common.loader = \
\"${catalina.base}/lib\",\
\"${catalina.base}/lib/*.jar\",\
\"${catalina.home}/lib\",\
\"${catalina.home}/lib/*.jar\"
I have removed the double quotes and that fixed the problem. Correct definition:
common.loader = \
${catalina.base}/lib,\
${catalina.base}/lib/*.jar,\
${catalina.home}/lib,\
${catalina.home}/lib/*.jar
Also, STS has quietly added Tomcat 8 JARs (bootstrap.jar, etc) to my Tomcat 6 launch configuration. While I had these JARs on the classpath, everything worked fine. But once I discovered and removed them, Tomcat 6 started breaking with the error in the original post.

I started to have the same issue out of nothing as well. We are using Java 1.7 in our project, but I also have Java 8 installed on my machine for experimenting. Even though everything is still configured to use 1.7 (I never changed the configuration and it was working fine), I think after some Java 8 update I started to get this issue.
After trying several things, I decided to uninstall all Java 8 related updates and installations; and made a fresh installation of Spring STS 3.6.2 with a new workspace. It seems to be working fine right now. You can try this if you also have a similar environment.

Sqlite java.lang.UnsatisfiedLinkError in linux

I have a program that uses Sqlite database. It works fine on Windows (exported jar or directly in Eclipse) but when I move it to linux server (plan is to use run it at certain intervals, cron job). I'm exporting it to jar from Eclipse and packing the sqlite-jdbc4-3.8.2-SNAPSHOT.jar with it. Error is this:
/$ /usr/bin/java -jar /home/username/Software.jar /home/username/
java.lang.UnsatisfiedLinkError: /tmp/sqlite-3.8.2-amd64-libsqlitejdbc.so: /tmp/sqlite-3.8.2-amd64-libsqlitejdbc.so: failed to map segment from shared object: Operation not permitted

....
So before you ask, I've made sure that sqlite-3.8.2-amd64-libsqlitejdbc.so in /tmp/ has all permissions (rwxrwxrwx). Still that native library is causing problems. It does get copied in /tmp/ folder though. That being said I totally suck in Linux... and for that reason I'm pretty much clueless what to try next.
What should I do? Switch connector?
EDIT:
Solved the problem by using System.setProperty("java.io.tmpdir", "/home/username/"); Apparently it for some reason couldn't execute the native library from tmp folder... Probably because it was created by root. Also I had to revert back to sqlite-jdbc-3.7.2.jar because the new one crashes on linux.

I had same problem, and I found the solution in this GitHub issue:
JAVA_OPTS=-Djava.io.tmpdir=/path/to/some/other/tmpdir bin/cerebro
Also look at this other SO answer.

how can I use jpcap library in my project?

I am using Netbeans 7, and I have 32 bit JDK version 1.7.0.40. I want to use jpcap library to analyze incoming packets.
I do following to be able to use jpcap.
I added "jpcap.jar" into my project's library.
I copied "jpcap.dll" into my JRE/bin
I copied "jpcap.jar" into my JDK/jre/lib/ext
I copied "jpcap.jar" into my JRE/lib/ext
However, I get the exception below:
Exception in thread "main" java.lang.UnsatisfiedLinkError: jpcap.JpcapCaptor.getDeviceList()[Ljpcap/NetworkInterface;
at jpcap.JpcapCaptor.getDeviceList(Native Method)
at src.JpcapAnalyzer.<init>(JpcapAnalyzer.java:19)
at src.Main.main(Main.java:31)
Java Result: 1
I appreciate for any recommendations.
Edit :
After 2 weeks posting this question, I received no answers. Then I want to share my experience with the community.
I tried another library,jnetpcap, which can be downloaded at https://sourceforge.net/projects/jnetpcap/. I easily implemented it. You can use this library both in 32 bit and 64 bit OS and JDK.

What is libmuxer library ? If I run my server or application then I find these

If I run my program or server then I find alsways this error message. Can anyone tell me and help me please.. I will be very thankfull to you.

"...this indicates that the Native Libraries are not properly being picked up the Weblogic server. This happens when the weblogic installed as 32 Bit on a 64 Bit Operating System or vice versa. In such scenario we need to explicitly specify the path to the Native Library."
Add the following to the setDomainEnv.sh
-Djava.library.path=/opt/bea/wlserver_10.3/server/native/solaris/sparc64/
Enable "Native IO" check box under each servers Tuning Tab.
Restart the servers.

I have the some problem, and thanks to sᴜʀᴇsʜ-ᴀᴛᴛᴀ for the hint! It looks like a 32bit/64bit issue. By the way, I'm using WebLogic 12 on a 64bit Centos5.
Note that the libmuxer.so is provided with weblogic for many archs, in fact
$ find $MW_HOME -name *muxer*
/application/weblogic/wlserver/server/native/macosx/libmuxer.jnilib
/application/weblogic/wlserver/server/native/linux/s390/libmuxer.so
/application/weblogic/wlserver/server/native/linux/ia64/libmuxer.so
/application/weblogic/wlserver/server/native/linux/x86_64/libmuxer.so
/application/weblogic/wlserver/server/native/linux/i686/libmuxer.so
/application/weblogic/wlserver/server/native/linux/s390x/libmuxer.so
I edited the file $MW_HOME/wlserver/common/bin/commEnv.sh, where I found
#JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT=false
and updated with
#JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT=true
This worked for me, the Error you reported is gone.
Good luck!

Jacob (Java / COM / ActiveX) Throws ComFailException

I am using Jacob a Java-COM bridge and I have placed the required dll to -C:\WINDOWS\system32\jacob-1.14.3-x86.dll. I have also added the required jar file to -
C:\Program Files\Java\jdk1.6.0_18\jre\lib\ext\jacob-1.14.3.jar.
Until yesterday I was able to use it, today I uninstalled some unrequired .Net softwares on my machine and suddenly it stopped working and throws following error -
com.jacob.com.ComFailException: Can't co-create object
at com.jacob.com.Dispatch.createInstanceNative(Native Method)
at com.jacob.com.Dispatch.<init>(Dispatch.java:101)
at com.jacob.activeX.ActiveXComponent.<init>(ActiveXComponent.java:58)
My machine belongs to "x86 Family 15 Model 4 Stepping 3". I have tried to de-register/register the dll using regsvr32.exe but to no luck. I have no idea how to bring it to work again..other wise I will have to format my machine..geeks pls hlp me out !

I wonder if anyone faced similar problem by any chance..
Anyways I had no other option than to restore my machine to last working date.
I guess some JAVA-COM class entries would have been accidently deleted from the registry.
Had no idea which was it exactly..
Finally "System Restore" was my solution :)
