Table of Contents
System properties are configured with the -D option for the JVM. Since JEUS uses Launch JVM to start the server JVM, system properties must be set in each server configuration of domain.xml.
The following is an example of a system property configuration.
<domain>
<servers>
<server>
<name>server1</name>
<jvm-config>
<jvm-option>-Xmx512m -XX:MaxPermSize=250m</jvm-option>
</jvm-config>
...
1. The properties set in the domain admin server or server script are only applicable when using Launch JVM.
2. System properties must be carefully set because they affect the overall operation of JEUS and all applications. It is recommended to use the XML settings instead of the system properties.
This chapter describes the server system properties.

| Default | 100 |
jeus.managedserver.deploy.socket
| Description | Maximum number of boot time deploy connections used when applications are deployed in parallel to an MS from DAS. Note, if too many connections are configured for an MS, other MSs can be affected because the number of connections to DAS is limited. When application deployment is complete, the connection is released and the number of available connections in DAS increments. Even if the specified number is big, the actual number of connections is automatically reduced to the number of applications. |
| Default | 5 |

jeus.net.nio.write.repeat.count
| Description | Number of write attempts allowed for a single message. This is useful when a message in a socket is so large that the selector thread cannot write messages in other sockets.

All properties provided by Web engines apply not only to the JVM system but also to virtual hosts and web applications. For more information, refer to JEUS Web Engine Guide. "5.4. Configuring Virtual Hosts", JEUS Web Engine Guide. "5.4. Configuring Virtual Hosts", JEUS Web Engine Guide. "3.3.1. jeus-web-dd.xml Configurations".
TmaxSoft recommends applying web engine properties at the virtual host or Web application level rather than at the JVM system or web engine level.
This section describes the properties set at the web engine level, which can be set in domain.xml. The values set in these properties override those of jeus-web-dd.xml.
jeus.servlet.prevent-forcibly-threadlocal-memoryleak
| Description | If a web application uses the ThreadLocal variable and does not release it, a memory leak can occur. In this case, a web engine can forcibly reset the ThreadLocal variable when the web application is reloaded, redeployed, or undeployed to prevent a memory leak. Note, if this option is used, the ThreadLocal variable, which is set by another application, is also reset. |

This section describes the web application level properties, which can be set in jeus-web-dd.xml. These properties can be used as web engine or virtual host level properties.
The following is a list of properties that apply to each servlet or JSP engine.
jeus.servlet.response.cookie.version0Style

| Description | Like Tomcat, does not change information, such as Request URI and path, which are set in Original Request. |
| Default | false |
jeus.servlet.keep-original-query-string-on-forward
| Description | Option to preserve the existing string in the Request object or to overwrite it with the query string when forwarding. |
| Default | false |
jeus.servlet.keep-original-query-string-on-include
| Description | Option to preserve the existing string in the Request object or to overwrite it with the query string when including. |
| Default | false |
jeus.webcontainer.j2ee.compatible.forward

| Description | Sets the encoding to be used in response headers. |
| Default | null |
jeus.servlet.scan-servlet-container-initializers
| Description | Option to use ServletContainerInitializer, which was added in Servlet 3.0. In order to conform to the servlet standard, the scan job is executed by default, but the deployment time can increase. |
| Default | true |
The following is a list of properties that apply only to JSP engines.
jeus.servlet.jsp.reload
| Description | Option to support JSP reloading. |
| Default | true |
jeus.servlet.jsp.precompile
| Description | Option to support the JSP precompile function (a function that only compiles when calling JSP according to the precompile request parameters.) |
| Default | true |
jeus.servlet.jsp.print.null.as.emptystring
| Description | Option to use empty strings when displaying null. |
| Default | false |

jeus.servlet.jsp.jspParam.urlEncode
| Description | Option to encode URL parameters. |
| Default | true |
jeus.servlet.jsp.helpReloadNativeLibrariesByCallingSystemGC
| Description | Handles the JVMs whose native libraries are not properly cleaned while reloading JSPs. The native libraries are cleaned up when GC (Garbage Collection) is performed on the JSP class loader, so JEUS can only call System.gc() and cannot guarantee 100% GC. Therefore, reload can fail if System.loadLibrary() is used within the JSP. |
| Default | false |
This property value calls System.gc() and System.runFinalization(), which can degrade performance. TmaxSoft recommends not modifying JSPs that use native libraries while operating the system. The recommended method is to create a web application that uses the native library and dispatches it to the application. The web application, however, must not Context Auto Reload or redeploy.
jeus.servlet.jsp.ignore-filename-case
| Description | Option to use upper case and lower case letters for the JSP file name. This is applicable only in Windows. |
| Default | false |
jeus.servlet.jsp.assure-utf8-file-encoding-detection
| Description | Treats JSP file encodings as UTP-8 even if Jasper does not recognizes it as UTP-8. |
| Default | false |
It is recommended to define the pageEncoding tag included JSP files.
JEUS conforms to servlet and JSP standards by default. However, API operations can change due to a standard interpretation error, incorrect implementation of requirements, standard document errors, such as unclear descriptions, and unmatched description between standard documents and the API document.
jeus.servlet.jsp.modern
| Description | Option to use JSP engine, which is compatible with JEUS 4. Only JSP 1.2 version is supported. The JSP engine is deprecated, so its use is not recommended. |
| Default | true |
jeus.servlet.request.url.allowNonStandardPercentCharacterUsage
| Description | Allows use of a single '%' in a URL. According to RFC 2396, 2.4.3. Excluded US-ASCII Characters, a single '%' is a reserved word for URL escape, so it must be used in a defined format. Therefore, clients have to send it as '%25'. |
| Default | false |
jeus.servlet.request.6CompatibleSetCharacterEncoding
| Description | The ServletRequest.setCharacterEncoding() encoding set must only apply to Request Body. In JEUS 6, a bug was found that allows the use of the encoding when reading Request Headers such as Query String and Cookie. Use this option when supporting applications written based on the JEUS 6 bug to avoid modifications to the application. |
| Default | false |
jeus.servlet.response.defaultContentType
| Description | Default value of Content-Type response headers. If this value is not NULL, response headers are set in the following cases: when calling ServletResponse.setCharacterEncoding() or ServletResponse.setLocale() and servlet did not call ServletResponse.setContentType() explicitly. However, this operation does not conform to the servlet standard for Content-Type response headers. |
| Default | null |
According to servlet standards, Content-Type Header cannot be included in response headers unless servlet explicitly calls ServletResponse.setContentType(). Also, when calling ServletResponse.getContentType(), null must be returned. Although these items are defined in Servlet 2.3, JEUS does not follow these rules.
In JEUS v7.0 Fix#1 and later, the default value was changed to null to conform to the standard. If applications operate based on the previous option, change this property value appropriately.
jeus.servlet.response.applyContentLanguageProperlyWithSetLocaleAPI
| Description | When ServletResponse.setLocale() is called after ServletResponse.getWriter() is called, Content-Language response headers must be set. Character encoding is not changed. If Content-Language is specified incorrectly and must be invalidated, set this option to false. |
| Default | true |
