java - Updating the pom.xml with Eclipse -


using eclipse m2eclipse plug-in, how update pom.xml, “maven->update project” won’t reset project configuration java 1.5? using eclipse kepler 4.3, java 7, , m2eclipse plug-in. create new maven project “create simple project (skip archetype selection)” checked , artifactid “test”. following warning.

description resource path location type build path specifies execution environment j2se-1.5. there no jres installed in workspace strictly compatible environment. test build path jre system library problem

i use following steps change compiler 1.5 1.7. 1. on project, right-click “properties” , select “java build path”. 2. go “libraries” tab. 3. remove old jre system library [javase-1.5]. 4. click “add library…”, select “jre system library”, , click “next>”. 5. check “execution environment” radio button , select “javase 1.7 …” adjoining menu. 6. click “finish” 7. click “ok”.

the warning disappears.

i right-click project , select “maven->update project”. click “ok”.

the warning message returns.

my understanding plugin uses pom.xml update eclipse’s current settings. how update pom.xml, “maven->update project” won’t reset project configuration java 1.5?

i looked @ these pages, think answers obsolete. warning - build path specifies execution environment j2se-1.4 what causes new maven project in eclipse use java 1.5 instead of java 1.6 default , how can ensure doesn't? maven not compile in java 1.6

for example, adding …

<configuration> <source>1.7</source> <target>1.7</target> </configuration>

… after version section in pom doesn’t fix problem.

you need use maven compiler plugin.

<build>     <plugins>         <!-- tell maven compile using java 1.7 -->         <plugin>             <groupid>org.apache.maven.plugins</groupid>             <artifactid>maven-compiler-plugin</artifactid>             <version>3.0</version>             <configuration>                 <source>1.7</source>                 <target>1.7</target>             </configuration>         </plugin>     </plugins> </build>

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
